农村生活污水生态处理技术研究进展

Research Progress of Ecological Technology for Rural Domestic Sewage Treatment

生态型处理技术是农村生活污水处理常用工艺,可依据农村地区的水质、地理特征和社会经济条件选择最佳的生态型技术,是农村水环境治理的迫切需求。文章归纳了近年来广泛应用于我国农村生活污水处理的各类生态型技术,介绍了多种生态技术组合工艺,以及生物强化生态处理工艺的研究进展,阐述了各种工艺类型的适用水质条件和对污染物的去除效果。中国的农村地区普遍存在经济薄弱问题,通过对比各种生态工艺的实际工程效能,以及其建设成本、技术特点、运维管理等指标,为我国广大农村地区选择适用于当地生活污水处理的生态处理技术时提供经验和指导。

Eco-type treatment technology is a common process for rural domestic sewage treatment.The best eco-type technology can be selected according to the water quality,geographical characteristics and social and economic conditions in rural areas,which is an urgent need of rural water environment treatment.This paper summarizes various ecological technologies widely used in rural domestic sewage treatment in recent years,and introduces a variety of ecological technology combination processes,as well as the research progress of enhanced biotechnology ecological treatment processes,and expounds the applicable water quality conditions of each process type and the removal effect of pollutants.Economic weakness is common in rural areas of China.By comparing the actual engineering efficiency of various ecological processes,their construction costs,technical characteristics,operation and maintenance management and other indices,it can provide experience and guidance in the selection of ecological treatment technologies suitable for local domestic sewage treatment in rural areas of China.
