摘要
针对老旧小区的排水现状,将建筑墙体边沿传统排水沟进行海绵化改造,采用多种过滤和吸附技术,构建从上至下的雨水净化系统.现场试验结果表明:初期雨水COD、SS、TP和NH3-N含量均降低 80%以上,SS去除率可达到 97.8%,出水水质优于市政杂用水及景观用水水质标准,单位使用和维护成本降低 10%—14%.
Abstract
Regarding the current drainage situation of the old community,the traditional drainage ditch along the edge of the building wall is sponge transformed,and a rainwater purification system from top to bottom is constructed by adopting a variety of filtration and adsorption technologies.The field test results showed that the COD,SS,TP and NH3-N contents of the initial rainwater were reduced by more than 80%,especially the SS removal rate could reach 97.8%.The effluent quality was better than the municipal miscellaneous water and landscape water quality standards,and the unit use and maintenance cost was reduced by 10%—14%.
