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 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.

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.

Eight measures of soil and water conservation(SWC) have successfully carried out for developing sustainable agriculture systems in hilly red soil region in southeast China since 2000. Economical, ecological and social benefits are assessed in this study to determine efficiency of these measures. All measures have shown a positive net present value of direct benefits in the computing period when an interest rate 10% used. And an evaluation system for comparing efficiencies of these measures have been built, indictors such us economical effects, payback period time, changes in soil erosion rates, nutrient content, microclimate, and social benefits are recommended. Forest enclosure, embankments, and biomass pools are the most economically measures with a short payback period while low efficiency forest reform, fruit trees planting and shifting slope to terrace measures had remarkable effects on reducing soil erosion and protecting soil and water resource, pear trees can be replaced by other cash crops to avoid long payback period.

A new type of inorganic flocculant, poly silicon boron ferric zinc sulfate (PSBFZ), was synthesized from sodium silicate, ferric sulfate, zinc sulfate and sodium tetra borate by co-polymerization. Comparative flocculation behaviors among poly-aluminium chloride (PAC), poly-ferric sulfate (PFS), poly silicate ferric (PSF) and PSBFZ were explored. The influences of pH, temperature, storage time and dosage on flocculation were studied. The results demonstrate that PSBFZ exhibits the best flocculation performance. Under the optimum conditions, the removal rate of turbidity and chromaticity were up to 99.6%, 99.4%, respectively.

Among the slightly alkaline mediums, the precipitating agent of sodium tetra phenyl boron(15g/l) precipitates the potassium ion among solutions, produce white potassium tetra phenyl boron precipitate, judge K+ content in solutions. Use sodium tetraphenyl boron as indicator to control BAF to extract potassium from Molasses Alcohol Wastewater. When K+ density is lower than 0.003 (mol/l), the bottom of colorimeter tube to be getting white pulverescent precipitate very thin, a small quantity of suspended particle in water. The result is obviously to control BAF absorbed-regenerated course.

Compression factor of natural gas must betaking account of when doing hydraulic calculations in super high pressure network. Several calculation methods and features of compression factor of natural gas were discussed. The compression factor of natural gas in a super high pressure and multiple source network was calculated separately by fitting S-K nomogram and state equations, then weighted average according to the quantity of gas supply of each source. Results indicate that hydraulic calculation of super high pressure and multiple source network, chosing calculation methods of compression factor of natural gas resonably is critical.
