MABR技术在农村生活污水处理上的应用

The Application Research on Rural Domestic Wastewater by MABR

以浙江省首个MABR农村污水治理示范项目为例,介绍了浙江农村生活污水排放特征,分析了该项目的工艺流程和系统布置,较为系统地探讨了COD、NH_4^+-N、TN、SS的降解规律及影响因素。结果表明,MABR系统启动速度快,运行稳定,有较高的抗冲击性能,对生活污水中各项污染物有迅速的去除能力和显著的去除效果,出水水质达到城镇污水处理厂污染物排放标准GB 18918-2012一级A标准。

Based on the first demonstration project of MABR domestic wastewater treatment in Zhejiang, this paper introduces rural wastewater discharge characteristic in Zhejiang, analyzes on the process flow and system layout of zhe project, and probes into the degradation low and influencing factors of COD、NH4^+-N、TN and SS.The results show that the MABR system has the characteristic of fast startup、stable operation.In addition, the system has a certain impact resistance and the results show that the removal ofthe pollutants from domestic wastewater were very effective, The effluent quality is up to GB 18918-2012 level A standard for "Discharge standard of pollutants for municipal wastewater treatment plant". MABR technology has wide application prospects in rural domestic wastewater treatment.
