A^(2)O-MBBR工艺应用于污水处理厂提标改造的案例分析

Case Analysis of A^(2)O-MBBR Process Applied to Upgrading and Reconstruction of Wastewater Treatment Plant

以广东省某污水处理厂为例,建立“厌氧-缺氧-好氧(Anaerobic-Anoxic-Oxic,A^(2)O)-移动床生物膜反应器(Moving Bed Biofilm Reactor,MBBR)+高效沉淀池+纤维转盘滤池”工艺系统,成功解决了城市污水处理厂中氧化沟池容不足和池型设计缺陷等问题,同时实现了污水处理出水的提标,使出水水质稳定达标。改造后,每吨水每天的运营成本约为0.52元。

Taking a sewage treatment plant in Guangdong province as an example,the process system of“Anaerobic-Anoxic-Oxic(A^(2)O)-Moving Bed Biofilm Reactor(MBBR)+high efficiency sedimentation tank+fiber rotary disk filter”is established,which successfully solved the problems of insufficient oxidation ditch tank capacity and tank type design defects in urban sewage treatment plants.At the same time,the standard of sewage treatment effluent is improved,so that the effluent water quality is stable and up to standard.After the renovation,the daily operating cost of each ton of water is about 0.52 yuan.
