关于上海市闵行区新农村生活污水处理试点工程的技术探讨

随着上海城市水环境污染治理力度的不断加大,市郊农村生活污水的处理将是改善水环境质量重要环节之一,为研究适合农村生活污水处理的方法.对农村生活污水的排放特征和处理技术进行了探索,建立了土壤渗滤+地表湿地处理结合的组合技术,并进行了示范工程研究,水质监测结果表明土壤渗滤+地表湿地相结合的生活污水处理技术具有除磷脱氮效率较高,投资和运行费用低,维护管理方便等特点.同时农村污水处理工程必须根据当地排放特征和生态环境,提高污水处理效率.     

Application of biochemical products as a bioremediation technique for domestic sewage treatment plants.

Biochemical products have been widely used for treatment of various types of wastewater. The treatment processes with the addition of biochemical products are quite attractive because of their simplicity, minimal use of equipment, they are environmentally friendly and are suitable for the removal of organic pollutants. The purpose of these products is to enhance the activities of beneficial microbes in order to improve treatment performance. This study was carried out to determine the potential of applying biochemical products in assisting and improving the performance of sewage treatment plants. In this study, four biochemical products, namely: Zeolite, Bio-C, Eco-B and Was-D, were applied to the sewage treatment plant. Analyses were carried out on several water quality parameters such as biochemical oxygen demand (BOD), chemical oxygen demand (COD), suspended solids (SS), oil & grease (O&G), phosphorus (P), ammoniacal nitrogen (AN) and sludge thickness (ST). From the results obtained, it can be seen that the overall performance of the treatment plant improved with most of the parameters studied were found to fulfill the DOE Standard B requirements. The performance of Bio-C was found to give better results than other products.     

絮凝剂在延庆县污水处理厂深度净化处理中的选择性研究

以微砂、硅藻土及S试剂作为絮凝剂,对延庆县污水处理厂原水进行絮凝试验,系统考察了3种絮凝剂进行处理时的最优条件。试验发现,硅藻土对原水有很强的絮凝和脱色效果,原水的CODCr、TN、TP去除率可分别达到37.9%、58.6%及98.08%,处理后水样上清液清澈,无悬浮物质。对比试验结果表明,微砂对原水的处理无效果,硅藻土处理原水的综合性能明显优于S试剂。     

Evaluation of virological quality of sewage from four biological treatment plants by a nested-PCR technique.

In order to determine the virological quality of sewage from four biological treatment plants in Greece (two in the city of Athens and two in the city of Patras), 92 raw sewage samples were analysed for the presence of enteroviruses and adenoviruses during the period from October 2000 to February 2003. A nested-PCR method was used in order to increase the sensitivity of virus detection. Enteroviruses were detected in 43 samples (47%) and adenoviruses in 75 samples (81.5%) of raw sewage by nested PCR. The more frequent isolation of adenoviruses in raw sewage indicated their stability as virological indicators of the pollution of the environment and their increased persistence in sewage.     

延庆县新农村澄清回流污水处理工艺典型设计

延庆县地表水主要来源于三库一闸、39座塘坝和河流,可利用水量为1.57亿m3;全县有机井1 330眼,可供水量为0.86亿m3。根据延庆县国民经济和社会发展远景目标纲要及总体规划,对全县生活、工业、农业和城市河湖环境需要进行预测,到2010年需水量为3.23亿m3,可供水量为2.30亿m3,缺水0.93亿m3。因此,水资源短缺是延庆县经济建设和发展的突出制约因素。
