农村现有污水收集系统的污染净化效能与成因解析
Analysis of pollution purification efficiency and causes of existing rural sewage collection systems
摘要
Abstract
Rural sewage collection systems have the capacity of pollution purification,and it is of great significance to analyze their purifying capacity to the effective treatment of rural sewage.This study constructed the existing rural sewage collection system including soil open ditch,concrete open ditch,concrete sewer and plastic sewer,and studied the pollution purification capacity and the causes of differences.The results showed that different types of existing sewage collection systems in rural areas generally had the purification capacity of chemical oxygen demand(COD),ammonia nitrogen(AN)and total phosphorus(TP).The purification effect of open ditches on COD,AN and TP was better than that of sewers,and the purification effect of soil or concrete collection systems was better than that of plastic collection systems.There were significant differences in bacterial communities in different types of rural sewage collection systems.The difference in functional bacterial distribution was the direct cause of the difference in purification capacity,and the difference in collection system type and material was the fundamental cause of the difference in purification capacity.This study puts forward some suggestions,such as using the existing open ditch system,avoiding blind hardening of open ditch and rationally promoting plastic sewer,which can provide support for the design optimization and scientific decision-making of existing rural sewage collection systems.关键词
