In order to improve the hydraulic permeability of wastewater infiltration system, two installations were designed with two with layers of red soil and cinder. At the load of 10 cm3/(cm2·d), the average removal efficiency of COD, TP, NH+4-N were different fillers for treating domestic wastewater at laboratory.1 installation was filled with layers of red soil and sand, while 2 obtained 91.1%, 97.6%, 48.7% and 80.1%,respectively by 1 installation; and 94.9%,98.3% and 89.0%,respectively by 2. The average effluent concentrations of nitric and nitrite were 54.7mg/L and 0.09mg/L by 1 installation; and 60.3mg/L and 0.15mg/L by 2. It was found that the removal efficiency of COD,TP and NH4+-N by 2 installation were better than those of 1, whilst 1 installation was more favourable for the removal of nitric and nitrite. The results further implied that layeredfilling can make good use of its filling performance. The hydraulic permeability of wastewater infiltration system and the removal of pollutants can also be effectively improved.
