多介质地下渗滤乡村污水处理系统的装置
摘要：
本实用新型涉及多介质地下渗滤乡村污水处理系统的装置。它是由透气层、毛管浸润层、透水层、多介质模块层、布水槽、集水层、防渗层和聚氨酯滤网组成，详细结构见说明书。本实用新型的优点是：用毛细管布水方式，增强了色谱分离效应；将多介质生态滤层引入重力过滤段，减少占地面积和提高水力负荷的同时，解决了易于堵塞问题。在微动力和水力负荷为15－25cm/m2d情况下，多介质地下渗滤系统对COD的去除率为85－95％，NH3－N为90－98％，TP为90－99％，能够实现乡村生活污水的深度处理和资源化。
摘要（英）：

The utility model relates to a device of a multi-media subsurface infiltration village sewage treatment system, which consists of a breathable layer, a capillary wetting layer, a permeable layer, a multi-media module layer, a water distribution groove, a water collecting layer, an impermeable layer and a polyurethane filter screen, and an instruction book shows a detailed structure of the device. The device of a multi-media subsurface infiltration village sewage treatment system has the advantages of utilizing a capillary pipe water distribution form to strengthen chromatogram separation effect, leading a multi-media ecological filter layer into a gravity filter section, and reducing occupied area and increasing water load while resolving the problem of easy block at the same time. Under a condition that microkinetic and water load is 15-25cm/m(2)d, removal rate of COD of the multi-media subsurface infiltration system is 85-95%, NH(3)-N is 90-98%, and TP is 90-99%, thereby the device of the multi-media subsurface infiltration village sewage treatment system can realize depth treatment and resourcezation of village domestic sewage.
