摘　　要：污水处理厂进水水质是城市污水处理工艺选择的关键环节,影响污水厂进水水质的因素众多,污染物在管渠输送过程中不断降解是因素之一。根据对选定管段上下游的水质水量监测结果,推求得到在管渠输送过程中污染物的降解常数;以南太子湖污水处理厂为例,运用指标分析法预测主干管起端的污水中各污染物指标初始值,根据各指标在干管中的降解规律,预测南太子湖污水处理厂进水水质指标。The quality of the influent water is a decisive factor determining the technical process of WTP,which is influenced by many factors,one of which is the degradation of contaminants in the pipeline.Based on the monitoring results of water quality and quantity in the selected pipe sections upstream and downstream,this paper calculates the degradation constant of contaminants in the pipeline.Taking the Nantaizihu WTP for example,the paper predicts the wastewater quality at the beginning of the main sewers,and the influent water quality of Nantaizihu WTP based on an analysis of the regularity of the degradation of contaminants in the pipeline.
