农村污水治理技术综述

Summary of Rural Sewage Treatment Technology

针对农村目前水环境污染的实际情况,寻求高效低耗的治理技术具有实际的意义。介绍了目前国内农村主要生活污水的收集模式、处理工艺以及受污染水体生态恢复技术,分析了国内农村水环境污染治理技术的研究和应用现状。污水收集方面,根据南北地形和气候差异介绍了多种不同的收集模式;污水治理方面,从生物技术、生态技术和组合工艺三个方面介绍了相关的处理技术;污染水体生态修复方面,着重介绍了水体清淤和水体调活的相关技术。根据不同处理工艺的原理和适用条件,归纳总结了适合当前我国农村生活污水的处理工艺。

Aiming at the actual situation of water environment pollution in rural areas,it is of practical significance to seek efficient and low-consumption treatment technologies.The current collection mode,treatment technology and ecological restoration technology of polluted water in rural areas were introduced,and the research and application status of domestic rural water environment pollution treatment technologies were analyzed.In terms of sewage collection,a variety of different collection modes are introduced based on the topographical and climatic differences between North and South.In terms of sewage treatment,relevant treatment technologies were introduced from three aspects:biotechnology,ecological technology,and combined processes.With regard to the ecological restoration of polluted water bodies,the related technologies of water body dredging and water body activation were introduced.According to the principles and applicable conditions of different treatment processes,the treatment processes suitable for the current domestic sewage in rural China are summarized.
