| Abstract: | 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. |
