摘要
本文介绍了土壤毛管渗滤（毛管浸润）污水净化—绿地利用系统的主要工艺，讨论了系统的污水净化效果。经过１６个月的试验运行，结果说明：该系统对生活污水中的有机物和氮、磷等具有很高和稳定的去除率，ＣＯＤ＞８０％，ＢＯＤ＞９５％，ＮＨ４Ｎ＞９０％，ＴＰ＞９５％，显示出很好的生物学净化效果。该系统特别适用于城市污水管网不完备的地区，是一项处理分散排放生活污水的实用技术。由于将主要构筑物设置在地下，且将污水处理与绿地植物的利用相结合，因此可以取得净化污水、美化绿化环境和节约水资源的综合效果。
This paper portrays the main technical processes of the integrated system for sewage purification and greenland utilization based on soil capillary percolation process.16month trial operation has proved that this system has an outstanding ability to purify waster water with stable and high removal rate of organic substances,nitrogen and phosphate.In addition,it shows a good purification efficiency for biological pollution.Thus,this system is a practical and efficient way to treat distributed drainage,and especially suitable for those areas without complete civil drainage network.The whole system is constructed under the ground,and it combines wastewater treatment with greenland utilization with comprehensive effect of sewage cleaning,landscaping and water conserving.
