摘要
本文介绍了江苏省宜兴市某小学以低影响开发理念建设雨灰水综合利用系统,该系统包括雨水收集系统、雨水处理系统及灰水处理系统。并基于该地区雨灰水污染特性,对该系统中雨水和灰水处理系统进行了调试。其中雨水主要污染物为SS和TP,进水平均水质分别为135.14mg/L、0.54mg/L,调试后出水水质为27mg/L、0.18mg/L,SS和TP的平均处理率为74.1%、54.3%;灰水主要污染物为COD、SS和TP,进水平均水质分别为198.8mg/L、92.2mg/L、0.71mg/L,调试后出水水质为92.0mg/L、17mg/L、0.27mg/L,COD、SS和TP平均处理率为53.8%、81.9%、61.9%。本文可为宜兴市小区雨水收集与回用提供参考。
This paper introduces the rainwater and gray water comprehensive utilization system of a primary school in Yixing City, Jiangsu Province. The system includes rainwater collection system, rainwater treatment system and waste water treatment system. Based on the characteristics of rain and water pollution in the region, the rainwater and waste water treatment system of the system was debugged. The major pollutants of rainwater are SS and TP. The influent water quality of SS is 135mg/L, the effluent quality is 27mg/L. SS removal rate is 74.1%. The influent water quality of TP is 0.54mg/L, the effluent quality is 0.18mg/L. TP removal rate was 54.3%%. Waste water main pollutants are COD, SS and TP. The influent water quality of COD, SS and TP are 198.8mg/L、92.2mg/L、0.71mg/L, respectively. The effluent quality of COD, SS and TP are 92.0mg/L、17mg/L、0.27mg/L. This paper can provide reference for rainwater collection and reuse in Yixing district.
