Abstract According to the data of the Central Statistical Office for 2017, the average amount of municipal waste generated per capita is 486 kg. Poland ranks last but one in terms of the amount of municipal waste generated. About 56% of municipal waste is processed, but still about 40% is landfilled. They may contain chlorides, especially those from the winter period, resulting from the use of deicing agents. Chlorides cause salinity of surface and ground waters and soil salinity, which in turn leads to deterioration of water purity and a decrease in biodiversity of aquatic organisms, changes in the microbiological structure and increased toxicity of metals. Chlorides also damage road surfaces and bridges, corrosion of plumbing pipes. Once the chlorine-containing sweepers are deposited in a landfill, this waste may contribute to an increase in chemical aggressiveness, which is important in the design of anti-filtration barriers, and in the rehabilitation of contaminated land and soil. The level of water and soil salinity has a significant impact on the critical infrastructure, especially in terms of water supply – the risk of corrosion of pipes and their decline in species biodiversity. An important role in the critical infrastructure is played by the storage of dustmuds – the risk of failure of security measures in storage yards. Therefore, it is very important to determine the salinity level in this stored waste. The salinity level of street sweeping waste from different street locations is not commonly studied. Therefore, such a study was conducted for a midsized city. The study shows that the highest chloride concentrations in street and sidewalk sweeping waste are found around manholes and the lowest concentrations are found on sidewalks. The aim of the research is to determine the amount of chlorides in sweepings in the annual cycle to determine the potential risk associated with their impact on selected aspects of the environment.
根据中央统计局2017年的数据,人均城市垃圾产生量为486公斤。波兰在城市垃圾产生量方面排名倒数第二。大约56%的城市垃圾经过处理,但仍有大约40%被填埋。它们可能含有氯化物,特别是冬季使用除冰剂产生的氯化物。氯化物引起地表水和地下水的含盐量以及土壤的含盐量,从而导致水的纯度下降和水生生物的生物多样性减少,微生物结构发生变化,金属的毒性增加。氯化物还会破坏路面和桥梁,腐蚀水管。一旦含氯的清扫机被放置在垃圾填埋场,这些废物可能会增加化学侵蚀性,这对于设计反过滤屏障和修复受污染的土地和土壤是很重要的。水和土壤盐度水平对关键基础设施产生重大影响,特别是在供水方面-管道腐蚀的风险及其物种生物多样性的下降。在关键的基础设施中,灰尘的储存起着重要的作用——储存场安全措施失效的风险。因此,确定这种贮存废物的盐度水平是非常重要的。不同街道清扫垃圾的含盐量一般没有研究。因此,这样的研究是针对一个中等城市进行的。研究表明,街道和人行道清扫垃圾中氯化物浓度最高的地方是沙井周围,最低的地方是人行道。这项研究的目的是确定每年循环中清扫中氯化物的数量,以确定其对环境某些方面的影响所带来的潜在风险。

Abstract Contemporary requirements on the quality of swimming pool water necessitate the improvement of the classical technology of its treatment. It is associated with the need to modernize installations or implement a new technology. The purpose of the analysis is to compare the effects of using classical and modified technologies for the treatment of swimming pool water in sports and recreational pools with similar characteristics. The research was carried out for ten pools, which were divided into two groups – pools with a classical water treatment system and a modified one. The conducted tests showed significant differences in water quality in terms of: pH, redox, permanganate index (CODMn), total organic carbon (TOC), free chlorine, combined chlorine, chloroform and trihalomethanes (THMs), and no differences in terms of: temperature, turbidity, nitrates and ammonium ion. It was found that the modified swimming pool water treatment technologies made it possible to obtain water of better quality with regard to physical, chemical and bacteriological properties.

Abstract The popularization of multimedia technologies and their active implementation into the process of the object-spatial environment organization is a pressing issue in scientific researches in the field of interior design. It was defined that the application of multimedia technologies, such as sensory touch objects, are fundamental in the process of the creation of an interactive interior for public use. The paper is devoted to revelation of the compositional location techniques of the interactive sensory objects in the interiors of public buildings. The complex of theoretical methods of scientific research has contributed to the analysis of the design of interactive public interiors through the prism of formal composition. The results of the study revealed the compositional techniques for interactive multimedia objects placed in the interior. We conclude that the location of sensory objects in the interior more often carried out by the use of composite grids: a rectangular mesh scheme and a radial scheme. Interactive multimedia objects add an adaptability and attractiveness to the interior, which is an important factor in the formation of public space.
多媒体技术的普及及其在对象-空间环境组织过程中的积极应用,是室内设计领域科学研究中亟待解决的问题。它被定义为多媒体技术的应用,如感官触摸物体,是为公众使用的交互式室内设计过程中的基础。本文旨在揭示公共建筑内部互动感官物体的构图定位技术。科学研究的理论方法的复杂性有助于通过形式构成的棱镜分析互动公共室内设计。研究结果揭示了放置在室内的交互式多媒体对象的构图技术。我们得出的结论是,感官对象在内部的位置更经常通过使用复合网格来实现:矩形网格方案和径向网格方案。交互式多媒体物品为室内增添了适应性和吸引力,是形成公共空间的重要因素。

Abstract This paper is a study on the problem of sludge formation in water treatment processes. Various physical and chemical processes used in technological systems of water treatment were described and those which are the source of sludge were indicated. The chemical composition of the sludge was presented, with particular emphasis on hazardous organic and inorganic pollutants. An essential part of the work was to consider the possibilities and ways of valorizing sludge. It was determined that the type of generated sludge depends on the applied process and its pollution degree depends on the type and quality of the water taken. Most of the sludge is formed during the coagulation process of surface waters, which may be contaminated with various heavy metals. Among the possibilities and methods of sludge valorization, an interesting way to use it is in construction, as an admixture to various building materials. It is also possible to use sludge as an unconventional adsorbent or reaction catalyst in the oxidation of organic pollutants present in wastewater.
摘要本文对水处理过程中污泥的形成问题进行了研究。描述了水处理技术系统中使用的各种物理和化学过程,并指出了污泥的来源。介绍了污泥的化学成分,重点介绍了有害的有机和无机污染物。这项工作的一个重要部分是考虑污泥增值的可能性和方法。结果表明,污泥的类型取决于所采用的工艺,污泥的污染程度取决于所采水的类型和水质。大部分污泥是在地表水混凝过程中形成的,可能受到各种重金属的污染。在污泥增值的可能性和方法中,一个有趣的使用方法是在建筑中,作为各种建筑材料的混合物。也可以使用污泥作为废水中有机污染物氧化的非常规吸附剂或反应催化剂。

Abstract Concrete is the most essential and demanding construction material that is mainly used to develop structural and nonstructural elements. Along with the better engineering properties, concrete has its drawbacks like the presence of pores and micro cracks, and this affects its properties like permeability and water absorption which tend to reduce its durability and strength. Carbon black dust (CBD) is one of the industrial byproducts that can be effectively used as an additive in concrete. It is a necessity for us to reduce environmental pollution arising due to CBD. This research paper attempted an investigation to assess the effect of CBD as an additive material into the concrete. The chemical properties of raw materials were determined by X-ray fluorescence (XRF) spectroscopy analysis and the mechanical properties of hardened concrete were carried out followed by destructive and non-destructive testing. Compressive strength of 150 mm concrete cubes was determined at 7th, 14th and 28th day of curing that contains various percentages (2.5%, 5%, 7.5% and 10%) of CBD. Concrete with 0% CBD served as the control specimen. On the basis of experimental investigations, the maximum compressive strength reported for concrete specimens containing 7.5% CBD as 17.23% was more than that of control specimen. At 10% CBD, strength got decreased but significant improvement with respect to control specimen was also noted. As per the chemical analysis, CBD contains substantial amount of fluxing and strengthening agents that improve the performance of concrete and it can be used as an additive admixture.
混凝土是最基本、要求最高的建筑材料,主要用于发展结构和非结构构件。随着更好的工程性能,混凝土有其缺点,如孔隙和微裂缝的存在,这影响了它的性能,如渗透性和吸水性,往往会降低其耐久性和强度。炭黑粉尘(CBD)是一种工业副产品,可以有效地作为混凝土添加剂使用。减少CBD对环境造成的污染对我们来说是必要的。本文试图对CBD作为混凝土掺加材料的效果进行研究。通过x射线荧光(XRF)光谱分析确定了原材料的化学性质,并对硬化混凝土进行了力学性能测试,然后进行了破坏性和非破坏性测试。采用不同配比(2.5%、5%、7.5%、10%)的CBD,在养护第7天、第14天、第28天测定150mm混凝土立方体的抗压强度。0% CBD混凝土作为对照试件。试验研究表明,含7.5% CBD的混凝土试件的最大抗压强度为17.23%,高于对照试件。当CBD含量为10%时,强度有所下降,但与对照相比也有显著提高。经化学分析,CBD中含有大量改善混凝土性能的助熔剂和增强剂,可作为添加剂外加剂使用。

Abstract Fire is one of the most common risks to the environment and human health. Fire, depending on the conditions of combustion and the type of fuel, can emit many toxic products. The paper presents numerical analyzes of the conditions that can occur in a building during a fire. The conditions were analyzed in terms of the safety of the occupants and possible emissions of pollutants into the atmosphere. The temperature, propagation of smoke, and emission of pollutants were analyzed. A numerical model was created using Fire Dynamics Simulator (FDS) software. The model represents a staircase and a corridor in a real building located at the Silesian University of Technology in Poland.

Abstract Eco-neighborhoods are constructed to answer the call to protect our planet, our common home. They were first initiated as a grassroots initiative by eco-enthusiast, and gradually adopted as national or regional strategies. Various methods for certification and labeling were created by international institutions and national governments which evaluate ecological, economical, and societal aspects of their design and functioning. The recognized gap in knowledge concerns the development of health-promoting places within eco-neighborhoods. In this paper, a comparative study of two small certified eco-neighborhoods in Paris – ZAC Boucicaut and ZAC Frequel-Fontarabe is presented. These neighborhoods were assessed with the universal standard for health-promoting places. The results suggest that within eco-neighborhoods it is possible to care for ecological aspects without compromising on health-promoting places.
生态社区的建设是为了响应保护我们共同的家园——地球的号召。它们最初是由生态爱好者发起的草根倡议,逐渐被采纳为国家或地区战略。国际机构和国家政府制定了各种认证和标签方法,以评估其设计和功能的生态,经济和社会方面。公认的知识差距涉及生态社区内促进健康场所的发展。本文对巴黎两个小型认证生态社区ZAC Boucicaut和ZAC Frequel-Fontarabe进行了比较研究。这些社区按照促进健康场所的通用标准进行评估。结果表明,在生态社区内,可以在不影响健康促进场所的情况下照顾生态方面。

Abstract The paper describes the problems of intentions of the rapid introduction of BIM technologies in the construction industry of Ukraine. The research methodology involves analysis of national building standards, BIM technologies that have already been partially tested and a new logical structure of design processes in the logic of BIM technology in Ukraine. It is proposed to introduce into the design practice a number of actions aimed at harmonizing the key stages of BIM-technologies development with the regulatory framework. The European LOD stages and Ukrainian stages of designing are compared; it is proposed to introduce and gradation enshrine it in state building standards. The correctness problem of competitive tender documentation form for the development of project documentation in Ukraine is highlighted. The issue of the need for a detailed review of European Union standards in terms of national specifics and their gradual implementation in the Ukrainian legal framework was raised. It is proved that the proposed measures will improve the quality of design solutions in terms of economic feasibility and environmental friendliness, and government agencies will be able to qualitatively control all design and construction processes.
摘要:本文描述了乌克兰建筑业快速引入BIM技术的意图问题。研究方法包括对国家建筑标准的分析,已经经过部分测试的BIM技术,以及乌克兰BIM技术逻辑中设计过程的新逻辑结构。建议在设计实践中引入一些旨在协调bim技术开发的关键阶段与监管框架的行动。对欧洲LOD阶段和乌克兰设计阶段进行了比较;建议在国家建筑标准中引入并逐步纳入。强调了乌克兰项目文件编制中竞争性招标文件格式的正确性问题。有人提出,需要根据国家具体情况详细审查欧洲联盟的标准,并在乌克兰法律框架内逐步执行这些标准。事实证明,拟议的措施将在经济可行性和环境友好性方面提高设计解决方案的质量,政府机构将能够对所有设计和施工过程进行质量控制。
