摘　　要：以高教博园小区为例,研究了排水管网整治工程(污水零直排工程)的排查和设计过程。采用QV和CCTV排查高教博园小区的排水管道缺陷,污水管道的缺陷占比为64.79%,雨水管道的缺陷占比为74.57%。通过将合流立管改为污水立管和雨水立管以及对53处错混接点的改造,实现了雨水和污水分流。对施工后的效果进行了分析,对于化粪池的改造,既能防止管道堵塞,又为后续污水处理提供了合理的COD浓度,改造施工前晴天平均COD浓度252.5mg/L,改造半年后,雨天平均COD浓度达368.25mg/L,排查和设计相结合的模式对排水管网整治类工程项目具有促进效果。Taking the Gaojiaoboyuan Community as an example,this study investigated the inspection and design process of the drainage network remediation project(Zero direct discharge of sewage project).QV and CCTV methods were used to inspect the drainage pipe defects in the Gaojiaoboyuan Community,with defects in the sewage pipeline accounting for 64.79%.The defect rate for the rainwater pipeline was 74.57%.By converting the combined vertical pipes into separate sewage and rainwater vertical pipes,as well as renovating 53 misconnected junctions,the separation of rainwater and sewage was achieved.Regarding the renovation of the septic tank,it can both prevent pipeline blockages and provide a reasonable COD concentration for subsequent sewage treatment.The average COD concentration on sunny days before the renovation was 252.5 mg/L;six months after the renovation,the average COD concentration during rainy days was 368.25 mg/L.This indicates that the combined model of inspection and design has a positive effect on drainage network remediation projects.
