摘要

为提高土地渗滤系统水力渗透性能，构建了2套不同填料的渗滤系统，1装置由红壤与砂分层装填，2装置由红壤与煤渣分层装填，并将二者分别用于处理生活污水。在水力负荷10 cm3/(cm2·d)运行下，1装置对COD、总磷、氨氮的去除率分别为91.1%、97.6%、80.1%，2装置为94.9%、98.3%、89.0%；1装置出水硝氮和亚硝氮的平均浓度分别为54.7 mg/L和0.09 mg/L，2装置为60.3 mg/L和0.15 mg/L。试验结果表明，2装置对COD、总磷和氨氮的去除效果稍优于1装置，但1装置更利于硝氮和亚硝氮的脱除，进一步说明分层装填能充分利用填料性能，有效地提高了土地渗滤系统的水力渗透性能且保持了良好的去除污染物的能力。

Abstract

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

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.
