人居环境综合整治背景下农村生活污水处理工艺的选择

Selection of Rural Domestic Sewage Treatment Process under the Background of Comprehensive Improvement of Human Settlements Environment

农村生活污水就是农村居民在日常生活中产生的污水,不包括为日常生活提供服务的工业活动产生的污水,《农村人居环境整治三年行动方案》提出了农村生活污水治理的目标和要求。农村生活污水具有污水量小、比较分散、水量变化大、污水浓度低且变化大、可生化性好等特点。根据地区的经济发展水平、人口密度、水环境污染程度及环境容量要求,人们要做好农村污水处理规模分类,选择适宜的污水处理技术。

Rural domestic sewage is the sewage generated by rural residents in their daily lives, and does not include sewage generated by industrial activities that provide services for daily life. The "Three-Year Action Plan for Rural Residential Environment Improvement" puts forward the goals and requirements for rural domestic sewage treatment. Rural domestic sewage has the characteristics of small amount of sewage, relatively scattered, large changes in water volume, low concentration of sewage, large change, and good biodegradability. According to the regional economic development level, population density, water pollution degree and environmental capacity requirements, people should do a good job in the classification of rural sewage treatment and choose appropriate sewage treatment technology.
