中文摘要:

采用一种土壤过滤系统处理农村生活污水，分析了该工艺处理过程中COD_Cr、BOD₅、NH₃-N、全氮(TN)和全磷(TP)的时空变化规律。实验结果表明：去除季节效果由高到低依次为：夏季>秋季>春季>冬季。土壤过滤系统对COD_Cr、BOD₅、NH₃-N、TN和TP的最高去除率分别达到87.3%、88.2%、75.9%、59.3%和74.1%；在土壤过滤系统内，沿着水流的水平方向，各物质去除率逐渐增大。采用该技术处理后，排水中TN、TP的浓度较高，用于灌溉可减少化肥使用量和节省淡水资源。

英文摘要:

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 COD_Cr, 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.
