摘要
近年来,合流制管道雨天溢流污染和分流制雨水管道初期雨水污染日益严重,给城市的受纳水体带来了严重的污染和破坏.基于平均浓度法,提出了按照流域进行雨水径流污染总量计算的公式.经计算,Z市全年的雨水径流污染总量为TSS 2.54×107 kg,NH3-N 1.75×105 kg,TP 4.03×104 kg,COD 5.72×106 kg,BOD52.06×106 kg,TOC 5.92×105 kg.同时确定了Z市主要的雨水径流污染控制对象并提出有针对性的管理控制建议.
In recent years, massive discharge of pollutants from combined and rainwater sewer has posed severe damage to the aquatic environment in many cities. Based on the average concentration method, a new method for total pollution load calculation was proposed through dividing the urban areas by watersheds. Through this method, the total pollution load in City Z was calculated as: 25 396, 175.0, 40.3, 5 718, 2 064 and 591.6 tons, respectively for TSS, NH3-N, TP, COD, BOD3 and TOC. Meanwhile, the main pollution discharge source was discovered and some suggestions were put forward accordingly.
