摘　　要：以南方某发达省份G为对象,对城市污水收集处理情况进行了计算和分析,讨论得到地区差异会导致居民源头污染物的不同,进而提出基于居民生活污水污染测定的能辅助城镇生活污水集中收集率的评价方法,且分别选取不同特征的A、B、C、D区域测定不同类型的源头污染物浓度,得到综合源头污染物浓度分别为116.5、128.3、138.3、128.3 mg/L,计算得运输削减率分别为14.10%、19.80%、32.10%、46.10%。研究结果表明:建筑红线内排水体制、化粪池、生活用水规律与降雨对源头污染物产生量有明显影响,通过计算运输消减率能反应污染物在管网运输过程中的损失情况,对辅助城镇生活污水集中收集率直观的表征不同区域污水收集效能具有一定参考意义。Taking a developed province G in south China as the object,the urban sewage collection and treatment situation is calculated and analyzed,it is concluded that the regional difference will lead to the difference of source pollutants of residents.Meanwhile,the evaluation method of urban sewage collection efficiency based on the measurement of domestic sewage pollution was proposed,and the concentration of different types of source pollutants was measured in A,B,C and D regions with different characteristics,and the comprehensive concentration of source pollutants was 116.5,128.3,138.3 and 128.3 mg/L,respectively.The calculated transport reduction rates are 14.10%,19.80%,32.10% and 46.10%,respectively.The results show that the drainage system、septic tank、domestic water law and rainfall in the red line of the building have significant influence on the amount of pollutants produced at the source,the transportation reduction rate can directly reflect the loss level of pollutants in the pipeline transportation process,it has certain reference significance for the direct characterization of sewage collection efficiency in different regions by the central collection rate of auxiliary municipal sewage treatment.

关 键 词：污水集中收集率 污水运输消减率 生活污水源头污染物产生量
