Three-dimensional fluorescence spectrometry is a rapid analyzing method and is widely used in dissolved organic matter (DOM) characterizing and fingerprinting. In this present work, three-dimensional emission and excitation matrix (3DEEM) fluorescence spectrum was applied to characterize the fluorescence properties of dissolved organic matter in farmer household tourism wastewater and municipal wastewater. The results show that DOM fluorescence properties from various farmer household tourisms are characterized by protein-like, and high-excitation wavelength tryptophan-like peak is the strongest among all protein-like fluorescence peaks. Municipal wastewater also has same typical fluorescence peaks, while their fluorescence intensities are very relatively. Many protein-like fluorescence intensities of weir water are still close to it of municipal wastewater, though the wastewater is diluted and purified by the receiving water body. The polluting of wastewater from farmer household tourism to receiving water body shouldn¡¯t be ignored.

The concentrated leach ate of the Chengdu Leach ate Treatment Plant was collected as a subject of case study. It was a very dark coloured liquid possessing high COD, very low BOD5 and low ammonia nitrogen concentration. The combination of coagulation and fly ash absorption was used to treat the concentrated leach ate in this study. The effects of pH, coagulant dosage and settling time on COD removal in coagulation process were investigated by single-factor and orthogonal experiments. Results showed that the optimum value was approximately pH 5, aluminium sulfate dosage 1.5g and settling time 50min. The influence of operating factors followed the order: coagulant dosage£¾pH£¾ settling time. Fly ash absorption experiments were performed after finishing the surface modification of fly ash in acid condition. The effects of pH, fly ash dosage and stirring time on COD removal were also studied by single factor. Results showed that the optimum value was about pH5, fly ash dosage 2.5g and stirring time 2.5h. After finishing the final step of fly ash absorption, the overall remova1 rate of COD was above 80%.

The sellable pre-cross linking particle gel is a kind of surface cross linking pre-polymer, of which the effects of several important factors like temperature, salinity and the pH values on its swellable performance, visco-elasticity, thermal stability and enhanced oil recovery ratio were firstly evaluated. Then the NMR, an advanced visible technology, was used to represent the oil and water distribution laws in different core displacement processes by water, polymer and the swellable particle gel. The results show that the depth profile control agent used in this study has great strength, excellent salt resistance and thermal stability, and controllable particle radius, swelling rate and ratio. It can deviate the water flow direction at the high permeability formation to displace much of the remaining oil at the low permeability reservoirs.

Aimed at wet and dry paving types of floor heating, the temperature distribution of the floor structure and surface at the steady condition were discussed by numerical simulation, the analysis shown that the temperature distribution in wet and dry laying methods of floor heating has same influence, That is the floor surface temperature can increase with decreasing layer thickness, with the increase of the average supply and return water temperature, with increasing thermal conductivity of materials and reduce the supply and return pipe spacing, etc. Dry and wet of floor heating methods have each advantages and disadvantages. As a larger the layer thickness of the wet of floor heating, the thermal resistance larger, so surface temperature distribution more uniform, while the dry system is simple and easy to maintain pipeline, especially suitable to existing buildings converted heating into floor heating.

The adsorption of reactants over the commerciallized SCR catalyst suface was investigated by EPR, as well as the influence of H2O and SO2. The results showed that the V4+ over the catalyst could be oxidized under NO + O2 atmosphere, andNH3 was adsorbed on Brönsted acid sites. The amounts of V4+and super oxide ions were promoted at the presence of H2O andSO2 after adsorption. However, the intensity of Fe3+ decreased when H2O and SO2 were present, indicating the favorable effect of Fe3+ for anti-poisoning.

Develop and use renewable energy is importance for building energy efficiency and many countries made clear renewable energy development goals in the world. China is actively promoting Integrative Solar Architecture, solar heating and solar hot water systems are important part. In China, solar radiation is large in summer and only solar water heating needed, solar collector area need small. In winter, both solar hot water and solar heating needed, but the solar radiation is smaller, so the solar collector areas have multiplied. The relevant norms and the manual give the methods for calculation solar collector areas for solar heating and solar water heating used alone. But they did not give the method of how to calculation the solar collector areas when the solar hot water and solar heating used at the same time.

However, the current design of fire protection code is unable to stipulate them. Although it really resolved many difficulties in the engineering practice using the performance of fire protection design, it has also brought many problems like circumventing the standard requirement, derating fire load by choosing fire scenes at will, reducing safety standards due to depending on the management excessively, choosing technical parameter randomly, losing contact with reality in the evaluation analysis and so on. So people need to put forward the control of performance design application scope after analyzing some performance-based design cases of some large-scale commercial complexes, to determine the security goal combining the condition of our country and the safety management, to select the fire scenes objectively and actually and to formulate and improve the current standards after summarizing the performance design measures of the indoor commercial pedestrian streets and the large and middle-scale atriums even the common architectural shapes.

Uaing wastewater as irrigation water presents arising tendency in China, however, little is known about the potential ecological impacts of the practice. Samples, such assoil and plants, were collected from the Panjin Shuangtaiestuarine wetland and used in the experiments to assess the effects of the soil microbial community added nitrogen. Supplemental nitrogen was added as NH4Cl to three treatments at nominal concentrations of 7, 15 and 20 mg/L(representing the hypothetical concentrations found in potential wastewater). In order to compare, a control (no added nitrogen)was added. Soil samples were collected on several days during the tests to assess soil microbial community composition (bacteria, actinomycetes and fungi). Results showed that while irrigation of the wetland soil with water containing progressively higher levels of NH4+ appears to promote some changes in the relative abundance of bacteria and actinomycetes, the differences are not substantial. Based on these data, meeting irrigation needs with certain types of wastewater is unlikely to cause severe environmental stress to the soil microbial balance although, since effluents vary in composition, pre-irrigation data collection and review may be appropriate to ensure the wastewater will not cause undue stress to receptor species.
