研究目的:随着社会的深人发展，环境保护问题已成为我国在发展中日益突出的社会问题，关系到人民 的健康和社会经济的可持续性发展。本课题拟解决铁路沿线中小车站生活污水处理难的问题。
研究方法:根据铁路沿线各中小车站既有条件，利用土壤毛细管渗滤原理，选取壤土配比，参照中科院沈 阳应用生态所实验数据，设计土壤毛细管渗滤系统。
研究结果:采用本土壤毛细管渗滤工艺处理的污水满足GB8978-96(一级)排放要求。
研究结论:该工艺基建、维护运行等费用较低，净化生活废水效率较高，净水出水符合排放标准，有效地保 护了地下水。适用于铁路沿线中小车站的生活污水处理。
Research methods: According to the existing conditions of the stations along railway lines , the soil capillary percolation system was designed with the principle of soil capillary percolation, based on the selection of soil matching and the experimental data made by Shenyang Ecology Utilization Institute of China Academy of Science.
Research results: The wastewater treated with technique of soil capillary percolation meets the drainage requirements of Standard GB8978-96.
Research conclusions : This technique has the features of low costs for construction and maintenance and high efficiency for treating sanitary wastewater with meeting requirements of drainage and effective protection of underground water, which is suitable for treating the sanitary wastewater for the stations along railway lines.
