摘　　要：城市污水管网清污混流问题影响污水收集处理设施的安全稳定运行,有必要采取便捷有效、成本较低的方法对混流的权重比例进行诊断评估。以化学质量平衡模型为基础,构建了以常规水质指标为特征因子的污水管道清污混流权重定量测算方法,并设置3种水源类型、11个水质指标对形成的测算方法进行了模拟验证。结果表明,通过该方法能够获得相对准确的污水水量占比范围,可为实际污水管网清污混流定量诊断提供依据。Inflow and infiltration of extraneous water of urban sewage systems poses serious challenges for the operation of sewage collection and treatment facilities.It is necessary to diagnose and evaluate the ratio of sewage and extraneous water by a convenient and low-cost method.Based on the chemical mass balance model,construct a quantitative measurement to calculate the ratio of sewage and extraneous water using conventional water quality index as the characteristic factor,and set 3 types of source water and 1l water quality indexes to simulate and verity its feasibility.The results show that the measurement can get relatively accurate proportion range of sewage water and can provide technical reference for the onsite extraneous water inflow and infiltration diagnose.
