摘要
试验研究了陶粒、花生壳、核桃壳三种滤料对雨污混接系统的初期雨水过滤处理的效果。试验结果表明,三种滤料对雨水中的SS去除率均达到55%以上,对CODCr的去除率为40%。其中核桃壳滤料对初期雨水过滤处理效果最好。
This experiment researched on the effect of ceramsite, peanut shell, walnut shell filtering material' s disposal ability to the initial rainwater of combined sewer systerr~ The experiment results showed that the three kinds of filter media on rain water in the SS removal rate reached more than 55 % and the removal rate of CODcr is 40%. The filtering effect of walnut shell filter for initial rainwater is the best.
