北京市农村生活污水排放现状调研与分析

Investigation and Analysis of Rural Domestic Sewage Discharge Situation in Beijing Suburbs

随着农村地区经济的发展,水环境污染问题日益严重,进行北京市农村排水现状调查和分析、研究不同类型村庄污水排放特点及分布规律、计算不同区域污染负荷,为确定农村治污范围和优先顺序提供可靠依据已成为北京市新农村治污规划工作的迫切需求。通过污水排放的实地调研和对典型村庄的水质监测,进行农村生活污水排放时空变化规律的分析和污水排放量、排放系数的确定,以此为工程规划和设计提供基础参数。

With the economic development of rural areas, water environment pollution is increas- ingly serious. The rural sewage discharge situation in Beijing was investigated and analyzed, the sewage discharge characteristics and distribution regularity in different types of villages were studied, and the dif- ferent regional pollution loads were calculated to provide reliable basis to determinate the pollution control range and priority order. All these have already become the urgent demands for planning new rural pollu- tion control in Beijing City. Based on the spot investigation and water quality monitoring of typical villa- ges, the space-time change rules of rural domestic sewage discharge was analyzed, and the discharge quantity, discharge coefficient were determined to provide basic parameters for project planning and design.
