%X In order to control rural non-point pollution in Taihu basin, the permeable dam (PD)technique which combines constructed wetlands principles and rapid filtration mechanics was designed. The PD technique can bear shock load of water quality and quantity of rural non-point pollution by utilizing riverway cubage. Through the manipulative seepage of dam, water head is afforded for latter treatment units. The results of four months' running experiments showed that the seepage calculation of permeable dam was adapted to be calculated by the trapezoidal seepage, and the PD met the prospective requirement of holding a 14000m~3 runoff which occurred once per five days. The TN and TP removal rate of PD were 15.59% and 23.44%, respectively.
