土壤过滤系统处理农村生活污水过程中污染物的变化规律
Variation rule of pollutant in treatment process of rural domestic sewage by soil filter system
摘要
Abstract
By using a soil filter system to treat rural domestic sewage .The paper analyzed the change rules of space and time of COD Cr , BOD5 , NH3-N, TN and TP in the process of treatment .The result shows that removal efficiency from high to low is summer >autumn>spring>winter .The highest removal efficiencies of CODCr, BOD5, NH3-N, TN and TP in the process were 87.3%, 88.2%, 75.9%, 59.3%and 74.1%respectively .Within the soil filter system , the removal efficiency every substance increase with water flow direction.The concentrations of TN and TP in treated water are higher .These treated water that is used as irrigation can reduce the amount of fertilizer and save freshwater resources .关键词
