摘要
以上海市静安区走马塘河道为研究对象,通过比较常规混凝土护坡与生态护坡对河水中COD、TN与TP的去除效率考察两种材料对水质的净化效果。研究表明:常规混凝土护坡与生态混凝土护坡的COD、TN与TP去除率分别为26.41%、46.42%、37.22%和64.26%、73.50%、48.99%;生态混凝土护坡较高的去除效率主要是通过空隙内微生物降解与材料吸附协同实现的。
Taking Zhoumatang River in Jingan District of Shanghai as the study object, the removal efficiencies of COD, TN and TP in river water by the conventional concrete revetment and the ecological revetment are compared to inspect the purification effects of two materials on water quality. The results show that the removal rates of COD, TN and TP by the conventional concrete revetment and the ecological concrete revetment are 26.41%, 46.42%, 37.22%, and 64.26%, 73.50%, 48.99%, respectively. The higher removal efficiency of the ecologic concrete revetment is mainly achieved through the cooperation of micro-biological degradation and the material adsorption in the void.
