农村生活污水处理现状及工艺研究

Discussion on Status and Technology of Rural Domestic Sewage Treatment

日渐增大的农村生活污水无序排放,已经逐渐成为中国环境管理面临的新问题。文章分析了农村生活污水的排放特点、存在的问题以及处理的必要性,介绍了处理农村生活污水的生态系统技术和生物处理技术两大类处理方法的特点和主要原理。文章通过对CWT-M膜处理、SW一体化+人工湿地生活污水处理、ASPS生态湿地处理、AAO等四类处理设施实际运行监测结果的对比分析,指出污水处理设施及工艺的选择要因地制宜、科学设计,使相关设施达到应有的处理效果。

The disorderly discharge of rural domestic sewage is becoming a new problem of environmental management in Chi- na. This paper analyzed the discharge performance, problems and the necessity for treatment of rural domestic sewage. It intro- duced two main treatment methods for rural domestic sewage, ecological system technology and biological treatment technology. According to the practical running results of four facilities such as CWT - M, SW integration ＆ artificial wetland, ASPS wetland and AAO. The paper proposed that to achieve the treatment effect, the characteristics of local conditions must be taken into con- sideration in choosing the facilities and technology.
