摘　　要：以天津市纪庄子污水处理厂及其服务区域为研究对象,通过ArcGIS平台,联合遥感技术与InfoWorks CS软件,建立了纪庄子合流制排水管网模型。不同降雨重现期下的模拟结果表明,当重现期≤20年时,如果只对合流雨污水进行一级处理,纪庄子污水厂完全可以接纳合流制来水;与采用正常的二级处理相比,当遇到暴雨时污水厂适当采取强化一级处理,可有效减少污染物排放总量,保护受纳水体。The combined sewer system model for Jizhuangzi WWTP in Tianjin and its service area was established using the ArcGIS platform, remote sensing technology and InfoWorks CS software. The simulation results in different return periods showed that if relying only on the primary treatment, Jizhuangzi WWTP had enough capacity to receive combined wastewater when return period was less than or equal to 20 years. When heavy rain occurred, total pollutants in the outflow could be reduced effectively and the receiving water could be protected using the enhanced primary treatment rather than the conventional secondary treatment.
