摘要
随着我国“乡村振兴”“厕所革命”等国家战略的实施,我国农村生活污水的治理也越来越受到重视,但是农村生活污水不同于城市生活污水,它的治理在标准、模式、技术、运维等方面存在诸多问题。本文详细介绍了我国农村污水治理现状,针对全国不同地区农村生活污水处理工艺和典型案例,从处理技术、排放标准以及运维管理等方面进行了系统分析,重点论述了处理技术的优缺点,并结合农村自然的自净能力和面源污染的根本原因,提出了建立排放标准的合理前提,同时也介绍了智慧运维在农村生活污水处理中的积极作用。另外,根据农村居住分散、地势差异大的特点,强调了分散式处理的重要性,旨在从根本上解决农村生活污水收集难、处理复杂的难题,以生态处理模式实现美丽乡村建设。
With the implementation of national strategies, such as“rural revitalization strategy”and“toilet revolution”, the treatment of rural domestic sewage has also received increasing attention in China. However, rural domestic sewage differs from urban domestic sewage,and there are many problems in the standard, mode, technology, operation, and maintenance of rural domestic sewage treatment. This paper provides a detailed introduction of the current situation of China′s rural sewage;analysis of the treatment cases of rural domestic sewage in different regions of the country;and systematic analysis of the treatment technology, discharge standards, and operation and maintenance management. Focused on the advantages and disadvantages of the treatment technology, this paper puts forward the reasonable premise for the establishment of the discharge standard combining with the self-purification ability of rural nature and the root cause of non-point source pollution, and also discusses the positive role of intelligent operation and maintenance in the treatment of agricultural sewage.According to the characteristics of scattered rural residents and large differences in terrain, the importance of decentralized treatment is emphasized, so as to fundamentally solve the difficult problems of sewage collection and treatment, and realize the construction of beautiful countryside with ecological treatment mode.
