A^(2)O和MBR组合工艺在寒冷地区污水处理中的应用分析

Application of A^(2)O and MBR Combined Process in Sewage Treatment in Cold Regions

为进一步探究寒冷地区污水处理效果的提升路径,以一污水处理厂冬季出水水质不达标为研究对象,确定采用A^(2)O (Anaerobic-Anoxic-Oxic,厌氧-缺氧-好氧)工艺与MBR (Membrane Bio-Reactor,膜生物反应器)工艺相结合的方式进行污水处理,在设计整体方案的基础上,对具体的工艺流程及参数等内容进行全面优化设计,以完成工艺设计。从实际运行效果来看,设计的A^(2)O和MBR组合工艺在寒冷地区污水处理中取得相对较优的效果,证明其具有一定的实际应用价值。

In order to further explore the improvement path of sewage treatment effect in cold regions,the effluent quality of a sewage treatment plant in winter was not up to standard as the research object,and the combination of A^(2)O(Anaerobic-Anoxic-Oxic)process and MBR(Membrane Bio-Reactor)process was determined to carry out sewage treatment.Based on the design of the overall scheme,the specific process flow and parameters were comprehensively optimized design to complete the process design.From the actual operating results,the designed A^(2)O and MBR combined process has achieved relatively good results in the sewage treatment in cold regions,proving its practical application value.
