And it also have limited effect on deepwater treatment. Because of the shortcomings of the traditional floating island, the \"Combined Artificial floating island\" device, which combines the ecological floating island, activated carbon fiber and aeration, is proposed to study its purification effect on black-odorous water. After 22 days of experiment, the removal rates of COD, TN and TP reached 83.9%, 50.2% and 26.4% respectively for the \"Combined Artificial floating island\" combined treatment unit, while it reached 70.5%,39.2%and 17.5% respectively for the traditional ecological floating island. The experimental results show that the removal rates of COD, TN and TP in water body are increased by 13.4%, 11% and 8.9% respectively for the treatment of \"Combined Artificial floating island\" combined treatment unit, and the purification effect is greatly improved compared with the traditional ecological floating island. The “Combined Artificial floating island” uses synergistic effect of particle sedimentation, plant absorption, microbial degradation and activated carbon fiber adsorption to purify water. Therefore, it can adapt to water bodies with different water quality and water depth, and has wider application range and stronger adaptability. Introduction Artificial floating island (AFI) technology is a water surface planting technology using the principle of soilless cultivation, which achieves the purpose of purifying water quality through the absorption and degradation of nitrogen, phosphorus, COD and other pollutants by plant roots and microorganisms. As AFI has many functions, including reducing the dispersion of pollutants, water purification, ecological protection, and landscape effect, it has become a potential candidate for black-odorous water treatment [1-4] . However, due to the limited root area of the plant, only a small amount of biofilm attachment space can be provided. And because of the limited root length, there are limitations to the treatment of deeper water. At the same time, the low concentration of DO in black odorous water is not suitable for the growth of plants and microorganisms. Some materials have been discussed in previous studies for AFI concentration. Activated carbon has a large specific surface area and adsorption capacity, which is very suitable for water treatment [5-8] . Oxygen aeration has the effect of purifying water by forcing water through aeration; it provides oxygen for microbial oxidative decomposition of organic matter [9] . Based on previous research, we have produced Combined Artificial floating island (CAFI) , which link together with floating islands, activated carbon fibers and aeration. Its purification effect on black and odorous water was studied. More specifically, CAFI removes suspended solids (SS) from water by physical manipulation, and through the biosynthesis of pollutant","PeriodicalId":11324,"journal":{"name":"DEStech Transactions on Environment, Energy and Earth Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83323779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

And the mechanism of fiber reinforcement is revealed by experimental studies and numerical simulations. Firstly, by using the single fiber pull-out test, the results show that the maximum tensile force of single fiber under different embedding lengths increases with the development of age. Then based on a cohesive model, a three-dimensional finite element model is established to simulate the interaction between single fiber and cement-stabilized soil. The comparisons of numerical results and experimental results reflect that viscous interface parameters have vital effects on the interaction between single fiber and cement-stabilized matrix. Introducing the proper cohesive model, numerical results agree well with the experimental results better. Introduction The fibers can inhibit the expansion of cement-stabilized soil, also can improve crack resistance and long-term strength. In recent years, a large number of researchers studies the cement-stabilized soil reinforcement formula [1,2,3] by means of experiments in order to get better effects. According to the experiments, the reinforcement effects mainly depends on six factors: fiber volume fraction, fiber orientation, fiber shape, fiber material properties, matrix material properties, and surface contact characteristics of fiber and matrix [4]. And the understanding of the mechanism of fiber and matrix interaction relies on the single fiber pull-out test, which is a critical problem to decide the role of fiber and its reinforcement effects, and it is also the key point that researchers and engineers have been concerning about. For the accurate measurement of single fiber pull-out curves, many researchers have developed a variety of advanced precision apparatus for single fiber pull-out tests [5,6]. For further insight of fiber and matrix interactions, Cox introduced the shear lag model to established the mathematical model of fiber and matrix interaction [7], which solving stress field and strain field of the composite. Based on the shear lag model or more rigorous three-dimensional model of interaction between fiber and matrix, a large number of research results are obtained by the following researchers [8,9,10]. It is well known that the interfacial viscous effects is very important for the interaction analysis between fiber and matrix. Hsueh [11] considered viscous effects in the interface and the radial shrinkage in fiber pull-out process caused by the Poisson effect. These theoretical analyses are only applicable to simple shapes and boundary conditions, they are inconvenient for application in more complicated conditions. Morrison used the method of preset debonding length to establish the two-dimensional finite element model to calculate the results of fiber debonding and pull-out force, and he found that the effects of fracture energy relea","PeriodicalId":11324,"journal":{"name":"DEStech Transactions on Environment, Energy and Earth Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91315599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As one of the main consumers of resources, enterprises should be aware of the importance of environmental responsibility to society and itself. Based on this background, this paper analyzes the status quo of textile and garment enterprises fulfilling their environmental responsibilities, and selects twenty domestic listed textile and garment enterprises, which disclose the net assets return rate, environmental protection investment, operating income, number of technicians, R&D invested in five data sources and collected, and analyzed that the environmental responsibility of the company has a positive impact on the competitiveness of the company. Enterprises should strengthen their emphasis on the natural environment and assume their own environmental responsibilities. Introduction With the rapid development of the economy, people's quality of life has greatly improved. Along with the ever-increasing level of industrial development, the environmental problems brought about by production have become more apparent. This paper takes textile and garment enterprises as the research object, analyzes the relationship between corporate environmental responsibility and enterprise competitiveness through case and data, and explores the importance of enterprises to assume their own environmental responsibility for their development, which causes enterprises to pay attention to environmental responsibility. In the study of corporate environmental responsibility and corporate competitiveness, some scholars start to derive competitiveness from environmental responsibility and corporate performance. Zhang Shiyuan and Liu Li (2001) believe that the company is not responsible for environmental responsibility and profit. Contradictory, the two are mutually influential relationships. Feng Simiao (2014) concludes that the company actively fulfills its social responsibilities while operating, and its performance will be relatively improved, thus improving the competitiveness of the company. Some scholars include environmental responsibility in social responsibility and analyze the relationship between corporate social responsibility and corporate competitiveness. Huang Man (2018) believes that there is a close relationship between the fulfillment of corporate social responsibility and the core competitiveness of enterprises. Enterprises can take social responsibility while gaining benefits, and they can be better recognized by the society.

Based on that, the failure modes and stability of deformed bodies are studied in detail. According to the regional topographic map of deformed body, a two-dimensional limit equilibrium model is established. The three-dimensional model is established by using 3DEC discrete element software. The stress, strain and displacement under natural and rainstorm conditions are calculated and analyzed respectively, and the accuracy of the calculated results is determined by comparing with the monitoring data, so as to predict the deformation direction and rate of the deformed body. The longest movement distance of the deformed body along the shear outlet of different elevations is simulated separately to determine the affected area, which provides a reliable basis for making preventive measures for the construction site. Introduction The research on the stability of deformed slope is one of the key topics of Engineering geology, so many scholars at home and abroad have carried out in-depth studies [1-6]. The engineering geological conditions of the deformed body are complex, such as fissures, weak interbeds, faults and intersections of various structural planes distributed in the deformed body. At present, the stability evaluation of deformed body includes qualitative evaluation method, quantitative evaluation method and analysis and judgment method based on slope deformation material [8]. A deformed body is located above the slope of the material yard. The excavation at the foot of the slope has caused many tension cracks at upper part of slope and local collapse, which has a further slide tendency. Slope instability not only affects the normal operation of material yard construction, but also poses a serious threat to the safety of personnel, buildings and equipment at the foot of the slope. Therefore, it is urgent to reasonably evaluate the stability of the deformed body and accurately predict its possible degree of damage. Meanwhile, the research has far-reaching significance to ensure the smooth progress of the project construction. Taking the deformed body caused by excavation of a material yard as an example, this paper systematically evaluates the stability of the deformed body and the influence range of its failure by analyzing its deformation characteristics and utilizing the limit equilibrium theory and three-dimensional numerical simulation method, which provides a theoretical basis for the safe operation of the project.

Method for In-situ Remediation of Chlorinated Hydrocarbon Pollution The treatment of chlorinated hydrocarbon pollution represented by TCE and PCE in groundwater has been studied abroad for decades. The treatment methods include ectopic remediation and in situ remediation. Ectopic remediation requires turning over and excavating the soil, so that the soil structure is damaged and the cost is high, which is suitable for the treatment of areas with small contaminated areas[5].In-situ remediation USES a variety of techniques to degrade or remove contaminants in the source area (aerated zone, groundwater).At present, existing in situ remediation technologies are mainly permeable reactive barrier (PRB) and other technologies that integrate biology, chemistry and physics[7].In situ chemical oxidation (ISCO) is a method of feeding chemical oxidants into the contaminated in-situ regions to remove pollutants. This method relies on the strong oxidation of oxidants to break the chemical bonds of organic compounds such as chlorinated hydrocarbons and make them into harmless substances such as chloride ions, carbon dioxide and water. The chemical oxidants used must have little harm to the environment and be able to effectively destroy pollutants and make the generated oxidation products harmless[8].

This methodology could help engineers to raise a mathematical model to represent the behavior of system as a convincing function of process parameters. Many experiments in research and development in the paint preparation involve mixture components. These are experiments with mixtures in which the experimental factors are the components of a mixture and the response variable depends on the relative proportion of each components, but not on the absolute amount of the mixture. Thus the mixture components cannot be varied independently.

Goal of this paper is to encourage greater utilization of information technology in paint preparation research and development. Introduction The use of fire-resistant coatings is one of the most efficient ways to protect materials against fire[1]. Intumescent fire-resistant systems are chemical compounds which, when heated, melt, bubble and form a foamed char which acts as insulation for underlying steel structures[2]. Intumescent fire-retardant coatings composition usually contain three fundamental active ingredients: a carbon source (such as pentaerythritol-PER), a blowing agent (most often melamine-MEL), an acid source (generally ammonium polyphosphate-APP), and they are linked together by a binder such as polymer materials. Optimizing the formulations for a preparation of intumescent fire-resistant coating(IFRC) requires the fire resistant usefulness of several fire retardants collaboration to be confirmed. Three fire retardants were tested in this study: ammonium polyphosphate, pentaerythritol and melamine. Their fire resistant effects were evaluated using the fire-resistance tests of the International Organization for Standardization (ISO) [3]. From a limited number of experiments, a D-optimal mixture design was used to give a maximum of information.
