MBBR+臭氧电磁催化氧化用于污水处理厂提标扩建

MBBR + Ozonation together with Electromagnetic Catalytic Oxidation for Upgrading Project of Wastewater Treatment Plant

焦作市工业集聚区万方污水处理厂总规模为5×10~4m^3/d,分两期建设。一期于2009年7月建成投产,处理量为2.5×10~4m^3/d,进水以生物制药废水为主,采用水解酸化+A^2O工艺,设计出水水质执行《城镇污水处理厂污染物排放标准》(18918—2002)一级B标准。目前实施二期提标扩建工程,总规模达到5×10~4m^3/d,出水执行一级A标准,提标扩建工程采用生化池投加悬浮填料工艺(MBBR)、增加精密过滤和臭氧电磁催化氧化等措施,改造后出水水质达标。

The total treatment capacity of Wanfang wastewater treatment plant （WWTP） in Jiaozuo industrial area is 5×10^4m^3/d. The Wanfang WWTP would be constructed in two phases. The construction of the first-phase project with the capacity 2.5×10^4m^3/d was finished in the July of 2009. Most of the influent was pharmaceutical wastewater. The effluent quality met the first level B criteria in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918 -2002） via combi- nation processes of hydrolytic acidification and A^2O. At present, the second-phase upgrading project with capacity of 5×10^4m^3/d has been finished construction and put into wastewater treatment. After treatment via moving bed biofilm reactor （MBBR）, precise filtration, ozonation together with electromagnetic catalytic oxidation, the effluent of the second-phase project could meet the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （ GB 18918 - 2002）.
