小型人工潜流湿地装置在农村生活污水处理中的应用

Application of Small Artificial Subsurface Flow Wetland Device in Rural Domestic Wewage Treatment

我国农村生活污水的主要特征是排放总量大且分散,实现集中处理较困难,因此选择一种实用性强、经济性好、处理效率高、易运行维护与管理的农村生活污水处理技术和设备极其重要。为此,设计了一种人工潜流湿地污水处理一体化装置,该装置可事先批量生产、种好植物、驯化好微生物,便能实现即刻安装,即刻使用。并通过模拟生活污水对该装置的单池处理效果进行了测定,实验结果表明:该系统运行稳定,COD_(cr)去除效率在85%~91%,氨氮的去除效率在70%~79%,总磷的去除效率在68%~75%。

The main characteristic of rural domestic sewage in China is that the total discharge is large and dispersed,so it is difficult to realize centralized treatment.Therefore,it is very important to choose a kind of rural domestic sewage treatment technology and equipment with strong practicability,good economy,high treatment efficiency and easy operation and maintenance.In this paper,an integrated device for sewage treatment in subsurface flow wetland is designed.The device can be mass-produced in advance,plant plants,and domesticate microorganisms,which can be installed and used immediately.The experimental results show that the system runs stably and the removal efficiency of CODCR is between 85%and 91%.The removal efficiencies of ammonia nitrogen and total phosphorus were 70%~79%and 68%~75%respectively.
