Fruitful resources of solar energy in China have a huge prospect to development and utilization. In this paper, an elementary school classroom located in alpine region has been studied to estimate the potential benefits of solar energy used in house heating. The effectiveness of Warming in classroom with attached sunspace has been analyzed based on solar radiation received at unit area. Results show that attached sunspace is possible to receive the effective solar radiation of average 41.6 MJ/M2¡¤Day and achieve indoor warming of daily average 13¡æ in a heating period (from September of this year to April of next year). They are consistent with the actual results of survey. Therefore there will be a widespread prospect of utilization of solar energy in house heating, if attached sunspace is constructed by inexpensive material.

Different ethanol concentration of gasoline components have a significant influence on the permeability of aquifer medium. Because the different of pollutant concentrations will change the environment of aquifer medium, bring on jamming the pore space of medium and influence the hydraulic conductivity and bioremediation of pollutants in aquifer. This study focuses the environmental influencing factors of permeability on contaminated porous medium via four sand columns experiments. Results show that environmental influencing factors of permeability are dissolved oxygen, temperature, PH value and conductivity, and the dissolved oxygen is the main influencing factor of permeability.

Biogas yields and methane productivity were studied at different temperatures (15¡æ, 20¡æ, 25¡æ, 30¡æ and 35¡æ) by the way of anaerobic fermentation experiment which takes wine manure as biogas fermentation raw material, and take the sediment from rural methane fermentation as inoculate matter. The results indicated that temperature affected the material consumption time, the higher temperature, the faster material consumption, and then, fermentation period was become shorter too. However, more gaseous impurities were produced when anaerobic fermentation temperature increased relatively. Temperature of anaerobic fermentation had a great influence on methane production. Low temperature goes against the production of methane. Biogas yield and methane yield can ascend to the peak quickly at high anaerobic fermentation temperature. Taking into account production efficiency and the quality of digestion, temperature condition of 30 and fermentation period of 31d ¡æ in swine manure anaerobic fermentation are suitable for large scale farms.

In this work, the advanced treatment of the biologically treated wastewater of a textile plant using combination of ozonation and two-stage biological aerated filter (BAF) was studied. Comparing different ozone dosing methods, it was found that the integrated device including ozonation and BAF, allowed a higher COD (chemical oxygen demand) and color reduction. Comparing different treatment processes, it was found the combination of the integrated device and up-flow biological aerated filter allowed a higher pollutant reduction. After the ozonation and two-stage biological treatment, an effluent was obtained with the average COD of 26.7 mg/L, turbidity of 4.2 NTU, SS(suspended solid) of 2.0 mg/L, ammonia nitrogen of 0.6 mg/L and color of 2 degree.

It had been U.S. Environmental Protection Agency(EPA) suggested the 16 polycyclic aromatic hydrocarbons(PAHs) must take priority of control due to potential harm to people's health. The extensive amount of data show the part of PAHs source from the utilization of the coal. During the coal conversion process, PAHs released may be divided into two categories according to their formation pathways. One category is derived from complex chemical reactions and the other is free PAHs transferred from the original coals. The main idea of this study is to quantitatively analyze the total PAHs amount in the raw coal and get the relationship between PAHs and the coal properties. The results indicated that the amount of the PAHs of coal achieve to the maximum in the carbon content at 80.41%, the volatile yields at 37.19%, the O/C ratio as 0.1 and the H/C ratio as 0.8. The results also show that the rapid Soxh let extraction technique used in PAH extraction is more efficiency and environmentally friendly than the conventional Soxh let extraction technique.

This paper uses co-integration theory and time series cross-section data model to empirically study cointegration relationship between China¡¯s coal consumption and economic growth in eastern, middle and western regions of China firstly. The research results show that there is a stable long-term equilibrium relationship between coal consumption and economic growth in the eastern region, this is a unidirectional relationship from economic growth to coal consumption. In middle region of China the obvious bidirectional long-term causal relationship and the bidirectional short-term causal relationship co-exist. However, there is a long-term co-integration relation in western region and the short-term causality is not tenable. And then combined the data of economic growth, energy and coal consumption in China, we conclude that relationship between coal consumption and economic growth is significantly different among various regions because of the level of economic development and its operation mechanism. Finally, some policy suggestions are put forward to promote the coordination development of energy and economy in various regions of China.
