AnGMBR处理低浓度废水的运行特性

采用厌氧颗粒污泥床膜生物反应器（AnGMBR）对模拟生活污水进行处理,并对其运行特性进行研究.结果表明,在室温、进水COD 260mg/L的条件下,AnGMBR的出水COD能稳定维持在30mg/L以下,即使HRT降至5h,系统的出水COD仍满足一级A排放标准.AnGMBR的总甲烷转化量在0.234~0.271L/g COD_去除之间,其进水COD约有61%~70%转化为甲烷.AnGMBR在运行过程中颗粒污泥的粒径、机械强度没有较大的差异,颗粒污泥具有较好的稳定性.经过一段时间的连续运行,AnGMBR的TMP稳定维持在35kPa左右,膜丝在经过清洗后,其性能能够得到有效的恢复.AnGMBR中用于颗粒污泥流化所需的能耗较低,膜滤出水为主要的需能部位,系统各阶段的产能均能满足能耗需求.AnGMBR高效稳定的运行表明,AnGMBR作为一个低耗高效的废水处理系统,具有良好应用潜力.     

城镇化进程中经济、社会和环境效益相关性探析--以山东省昌乐县为例

经济、环境和社会三效益共同提高是实现一个地区可持续发展的前提。通过定性分析，对山东省昌乐县近年来的经济增长、环境变化、能源消耗以及人民生活和社会进步等方面建立指标体系。通过定量分析，从相关分析的结果中发现经济的发展、城镇化水平的提高与能源的消耗、环境的污染“同步”，而与人民生活和社会进步却是“非同步”，说明昌乐县农村城镇化的质和量之间有很大的差距。

FACTUAL INPUTS FOR ALLOCATION DECISIONS CONCERNING SCARCE WATER RESOURCES1

ABSTRACT: Factual inputs which may be useful for completing first-order assessments to aid decision-making on the allocation of scarce water resources are compiled. Water needs of major manufacturing industry groups and of minerals industries show wide variations in several measures of water use intensity. The chemicals and allied products and primary metals industries dominate the total water intake and consumptive water use by manufacturing industries. Consumptive use per employee for the petroleum and coal products industry group is nearly 2.5 times higher than that for any other industry group. Estimates of the water requirements per unit energy output for energy-processing systems vary by as much as an order of magnitude. Agricultural water use is larger than that of any other industry but water use for irrigation is not expected to increase significantly by the year 2020. In California, the production of crop calories and proteins per unit of irrigation water applied may vary by more than an order of magnitude. Crops which offer larger monetary returns per acre are irrigated most frequently.     

Resources consumption and wastes emission analysis for two manufacture processes of siliconit

Silicon carbide (SiC) heating elements (siliconits) are widely used at high-temperature fields. The raw materials, manufacture process and application fields of siliconits are all related to heavy energy consumption and pollutions, and bring high environmental loads. The resources consumption and pollution emissions in siliconit manufacture process were quantificationally estimated by input/output method. Difference between two traditional techniques to produce siliconits in China was also compared and analyzed. The results show that siliconit manufacture processes consume large quantities of resources because the furnace is open to environment and too much thermal-protection materials are used. For the thick-end technique is more complicated and the thick-end siliconits have a bigger size and mass, there are more resources and energy consumptions and pollution emissions for thick-end process than that for equal-diameter process. Some suggestions were introduced to improve the traditional techniques and a new process was designed. It is the most important that the open furnace should be replaced by close vacuum furnace. Sintering and siliconizing process can be combined into one high-temperature process. As results of process simplification and vacuum sintering, resources and energy consumption and wastes emission can be decreased remarkably.

Analysis of Influences between the Energy Structure Change and Energy Intensity in China

In this article, based on the data of the energy statistics from 1980 to 2004, we analyze the relationship between the primary energy structures, technique, management, and the energy use per unit of GDP based on the path analysis approach and present the degree of the direct, indirect, and the overall influences of the primary energy structures on the energy use per unit of GDP. The results show that the technical change and management level play a decisive role in the energy use per unit of GDP, and the ratio of oil consumption was the major limiting factor to energy use per unit of GDP. We then found the model of the energy use per unit of GDP and the structures of the primary energy consumption, eliminated the multicollinearity in the model with the path analysis result, and finally, analyzed the influence of the primary energy structure on the energy conservation.
