In the paper, the biosorption of Pb(II)and Cu(II) ions from contaminated water using a bacterial strain was studied in a batch system. The bacterial strain isolated from heavy metals-contaminated soil was identified as Bacillus sp. The optimum conditions of biosorption were determined. Lead and copper were removed effectively at the concentration that was lower than 100 mg/L. And the concentration of bacteria was also an important factor in removal of heavy metals. The results indicated that the strain Bacillus sp. is a suitablebiosorbent for the removal of Pb(II) and Cu(II) ions from contaminated water.

Using strain JM-1 producing biodemulsifier isolated from cold rolling plant emulsion wastewater as the starting strain, the optimum preparation conditions of the biodemulsifier were obtained by the experiment of carbon source, nitrogen source, trace element, and ratio of carbon to nitrogen. The concentration of the lip peptide reached 1.62 g/L, which was 22.73% higher than un-optimized. The biodemulsifier preparation kinetics were investigated. The kinetic models of strains growth and lipopeptide formation were established by Matlab, providing a good description of temporal variations of biomass, and product in JM-1fermentation. These models were applied to guide the industrial production of the biodemulsifier.

This paper presents coal consumption of electricity generation in China under different energy scenarios of the given long-term energy policies. Long Range Energy Alternatives Planning 2008(LEAP 2008) software is used to develop a simple model of electricity demand and to estimate gross coal consumption of electricity generation in China until2030 under these scenarios. And, time-serial emission inventory of As is also built in the method of emission factors based on fuel consumptions. The results show that the coal consumption will increase by 4 times, amounting to 5.92 billiontces under BAU scenario. The total emission of As is 20.7Mtces with an average annual growth rate of 6.6%. UnderENR scenario, the total reduction of coal consumption and Asemission may reach 25.89% and 26.82% respectively compared to that in BAU scenario.

The removal of CODMn, NH4+-N from micro-polluted raw water were investigated by zeolite biological aerated filter process. Several selected test factors such as media height ofBAF£¬hydraulic retention time(HRT)£¬the air/water ratio and concentration of NH4+-N in raw water were studied in the article. The test Results showed that the removal rate of pollutants from the micro-polluted raw water would improve with the increase of media height at the hydraulic retention time of 30min and the air/water ratio of 1:1. CODMn¡¢UV254¡¢turbidity were removed mostly at the foremost height of440mm, and NH4+-N was removed mostly at the height of220~440mm. The average removal rates of CODMn were36.81%, 33.17% and 26.29% respectively at the hydraulic retention time of 15min, 30min and 60min respectively, air/water ratio of 1:1. When the hydraulic retention time is30min, 28.24% of CODMn and 90.57% of NH4+-N were removed at the air/water ratio of 0.5:1, and 31.20% of CODMn and 93.22% of NH4+-N were removed at the air/water ratio of1:1. When the air/water ratio was 2:1, the average removal rates of CODMn and NH4+-N were hardly improved. The appropriate hydraulic retention time and air/water ratio of ZBAF to treat micro-polluted raw Water were 30min and 1:1respectively.

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.

This paper is devoted to study wind environment in a dense urban areas from the ventilation perspective. In order to take the stochastic characteristics of city wind into consideration, the exceedance probability analysis method was applied using air change rate as the index. The air change rate in the target domain was first obtained using CFD simulation for 16 wind directions and each building pattern. The CFD results demonstrated that airflow fields in the target domain were complicated and the air change rates depends greatly on wind direction. However, there is no direct correlation between street width and air change rate. The exceedance probability distributions were further calculated using the wind statistical data in Tokyo and used to analysis the influences of model orientation and street width. The results indicated that both factors affects the ventilation performance in the target domain significantly. The proposed evaluating approach is useful and effective for the urban ventilation design.

Energy Efficiency is the indispensable investment factor in the social economic growth. As a macroscopic direction to evaluate the energy effect, the energy efficiency mechanism is integrating into the actual operation of our urban development gradually from strategic perspective. As complementarities for Large-scale newly built, the construction of Public Rental Housing, which is at the exploration stage now, has to seek for more new mentalities based on the energy efficiency mechanism from advanced efficiency. This paper puts forward a new mode that we can build the Public Rental Housing by the way of existed residential renewal, which is aimed to solve the matching problem of energy efficiency and effectiveness, thereby making the social energy efficiency, economic energy efficiency and environmental energy efficiency harmony.

This paper presented the research results on the feasibility of the engineering application of high-efficient using straw technologies in the north rural areas of China. The biochemical conversion, the thermo-chemical conversion and the straw briquette process are all high efficiently straw stem using technology. The long wintertime and the cold climate limit the effect of biochemical conversion. The straw pyrolysis oil production technology still needs further research to promote engineering application. The straw gasification is a better technology for the high efficiently using straw stem, but the tar problem is a tough barrier. The direct combustion technology is simple and practical, but the burning efficiency should be further improved. The straw briquette technology is nearly mature for engineering application. Further more, the straw briquette has a good transport and storage properties. It can be a fuel pretreatment technology.
