摘要
地沟式土地处理污水净化机理主要是土壤的毛细管作用、吸附、过滤 ,沉淀作用、微生物降解作用和生物摄取作用。该方法处理污水效率高 ,BOD5、COD、SS、NH3-N、TP的去除率分别为 84%、80 .95 %、90 .1%、79.5 3 %、87.5 2 % ,且投资低 ,管理运行方便 ,是一种适用于中小城镇 ,以及旅游。
The mechanism of underground-ditch-pattern soil treatment technique for purifying polluted water mainly refers to soil capillary effect, adsorption, filtration, precipitation, microorganism degradation and organism assimilation, The practical technique is highly efficient, the removal rates of BOD 5 , COD, SS, NH 3-N, TP are 84%, 80.95%, 90.1%, 79.53%, 87.52%, respectively. Thanks to its low cost,easy operation and management, the technique is suitable for medium or small-sized cities and towns.
