摘　　要：城市污水集中收集率是城市污水系统运行效率的关键指标,城市污水污染物排放量是计算城市污水集中收集率的必需参数,但城市污水系统较高溢流量和缺乏溢流监测带来计算城市污水排污量的困扰。为此,应用城市污水系统模型和用水、污水处理、常住人口数等常规市政数据,首次提出了根据污水处理厂进水流量和负荷计算城市污水污染物排放量和污水集中收集率的2种方法。以面积约110 km^(2)、常住居民近100×10^(4)人口的城区污水系统为例,展示了应用2种方法的所需数据、具体步骤和计算结果,分析了2种方法各自的适用性。对流动人口、工商业活动和人日排污量等因素对城市污水污染物排污量的影响和估算进行了讨论。2种方法对当下国内和国外一些国家的城市污水排污量、污水集中收集率的计算和城市污水系统运行效率的评估,具有现实意义。The centralized collection rate of urban sewage is a key indicator of the operational efficiency of urban sewage systems,urban sewage pollutant loading is an essential parameter for calculating the sewage collection ratio.The high overflow of urban sewage systems and lack of monitoring data pose difficulties in calculating sewage collection ratio.By using the urban sewage system model and regular domestic water consumption and sewage treatment information,this study first time proposed two methods,which were based on the influent flow and pollutant loadings of the sewage treatment plant to calculate the urban sewage pollutant loadings and sewage collection ratio.The applicability of two methods was demonstrated including the required data,specific steps,and calculation results by a case of an urban area with almost 110 km^(2) square meters and nearly 100×10^(4) inhabitants in a city in the Yangtze Delta area.The applicability of each method was discussed.Furthermore,the effects of the commuters,industry and commercial activities,personal discharge load on the estimation of sewage collection ratio in the cities at different levels of economic development are discussed and analyzed.The methods introduced in this study had practical significance for calculating the sewage collection ratio and evaluating the operation efficiency of urban sewage systems in China and part of the other countries.
