南安市某农村集中式A^(2)/O-MBR工艺污水处理模式分析与应用

Analysis and application of centralized sewage treatment mode in a rural area of Nan’an City

当前,乡镇农村区域环保基础设施较为薄弱。农村污水无序排放、垃圾随意堆放,不仅造成农村生态环境的破坏,而且还直接威胁农村地表水、饮用地下水的水质安全。本文分析了现有农村污水收集处理模式及厌氧-缺氧-好氧膜生物反应器(A^(2)/O-MBR)的原理及适用,并以南安市某农村污水排放现状为例,详细介绍了农村集中式A^(2)/OMBR污水处理站的工艺设计,为农村污水处理提供新的思路与借鉴。

At present,the infrastructure of environmental protection in rural areas is relatively weak.The disorderly discharge of rural sewage and random stacking of garbage result in the damage to the rural ecological environment,and directly threaten the water quality safety of rural surface water and drinking groundwater.The existing rural sewage collection mode and the principle and application of anaerobic-anoxic-aerobic are analyzed in this paper.The current situation of rural sewage discharge in Nan’an City is taken as an example,the design of the bioreactor based on the anaerobic-anoxic-aerobic for rural centralized sewage treatment station is introduced as well,which provides new ideas and reference for rural sewage treatment.
