摘要
随着环保意识的不断提高,人们越来越关注于农村污水的治理状况。文章介绍了农村分散式污水的特点、来源、现状和问题,主要阐述了厌氧沼气池、人工湿地、净化槽、蚯蚓生态滤池、地下土壤渗滤技术、MBR工艺和不同的组合工艺技术等常用的分散式农村污水处理技术的研究状况,通过分析其优缺点来探讨其适用性,在其基础上优选将经济效益、社会效益与环境效益相结合的小型污水处理技术。最后,针对现今农村污水处理中出现的问题,从法律、道德意识、资金投入、技术创新的层面,对农村污水处理领域的发展趋势作出展望,以促进其发展。
With the continuous improvement of environmental protection awareness,people are paying more and more attention to the treatment of rural sewage.The article introduces the characteristics,sources,current situation and problems of rural decentralized sewage,mainly expounds anaerobic biogas digesters,constructed wetlands,johkasou,earthworm ecological filters,underground soil infiltration technology,MBR technology,different combined process technologies,etc.The research status of commonly used decentralized rural sewage treatment technology is to explore its applicability by analyzing its advantages and disadvantages.On its basis,small-scale sewage treatment technology that combines economic,social and environmental benefits is selected.Finally,in view of the current problems in rural sewage treatment,from the aspects of law,moral awareness,capital investment,and technological innovation,the development trend of the rural sewage treatment field is forecasted to promote its development.
