植物滤器降解杭嘉湖区域农村生活污水效应研究

Effects of Plant Filter on Degradation of Rural Domestic Sewage in Hangjia Lake Regions

在营养液膜技术基础上构建以盘培多花黑麦草为主要内容的植物滤器系统,来降解浙江省杭嘉湖区域农村—农户的生活污水。结果表明,植物滤器降解生活污水效果明显,在系统运行30天后,生活污水的COD,TN,NH4-N,TP,SS分别降解了89.3%,58.9%,86.4%,68.6%,85.7%。同时,过程表现出在运行前期降解幅度较大,而运行后期降解幅度相对较小。

Based on nutrient film technique,we have built up plant filter system to degradate the rural domestic sewage in Hangjiahu regions,which is mainly composed of Lolium multiflorum L strips.The results showed that most water quality parameters of rural domestic sewage including chemical COD,TN,NH4-N,TP,SS were removed significantly by 89.3%,58.9%,86.4%,68.6%,85.7%.In the earlier periods of system running,the water quality parameters aboved mentioned decreasing greatly,while in the later periods of system running,the water quality parameters decreasing slowly relatively.
