摘要
建设地下土壤渗滤系统处理农村生活污水试验工程.通过取样检测,数据进行分析,系统对COD、BOD5、NH3-N、TP的平均去除率分别达到了89.78%7、8.9%、97.13%和95.03%,效果理想.系统的出水方式对BOD5、NH3-N的去除有一定的影响,而上部作物的种类对处理效果略有影响.系统造价低,管理简单,卫生条件好,是污水资源利用的较好方法.特别适用于零星分散排放污水的治理,在广大农村具有较大的应用价值.
A test project of the subsurface soil infiltration system for rural domestic sewage treatment is built. Through some sample inspections and data analysis of the system, the average removal rates of COD, BOD5, NH3 - N and TP can respectively reach 89.78% ,78.9% ,97.13% and 95.03%, which have ideal effects. The effluent discharging modes of the system has some influence on the removal rates of BOD5 and NH3 - N, while the species of the crops on the upper part has a little effect on the treatment efficiency. This system has the advantages of low investment, convenient operation management, and good sanitation conditions. It is a better method to use sewage resource and a more suitable system for dispersed domestic sewage which has a great value in application in the vast rural areas.
