典型污水处理技术在北京市农村的应用分析

Application of typical wastewater treatment technology in rural areas of Beijing

为研究典型污水处理技术在北京市农村的应用情况,对膜生物反应器、人工湿地、生物接触氧化、缺氧/好氧等污水处理技术在北京地区的应用现状及处理效果进行了调研。6种典型污水处理技术在北京市均有应用,且不同的处理技术可满足不同的出水要求。处理技术的选择受到原水水质、污水排放量、出水应满足的标准要求、自然条件等因素的影响;在选择污水处理技术时,需要综合考虑各个影响因素及污水处理技术的特征。研究结果为实现北京市农村污水处理的可持续发展提供参考。

In order to study the application of rural sewage treatment technology in Beijing,six typical sewage treatment technologies,such as membrane bioreactor,constructed wetland,contact oxidation,and multistage anoxic/aerobic,were selected for investigation in Beijing area.The results showed that the selection of rural sewage treatment technology was affected by raw water quality,sewage discharge,effluent standard requirements,natural conditions and other factors.It is necessary to comprehensively consider each influencing factor and the characteristics of wastewater treatment technology before making a selection.This would provide a basis on realizing the sustainable development of rural sewage treatment in Beijing.
