摘要
某经济开发区污水处理厂针对进水B/C比偏低、二级出水中难降解COD指标较高的问题,在升级改造工程中采用上向流炭吸附澄清池作为深度处理的主体工艺。实际运行效果表明,该工艺处理效果优异,对难降解COD的去除率达60%以上,出水各项指标优于《城镇污水处理厂污染物排放标准》(GB 18918—2002)中的一级A标准。
The wastewater discharged by industrial development zone is characteristics by low val- ue of B/C and high content of refractory COD. In order to resolve this problem, upflow carbon-adsorption clarifier was used as the main advanced treatment process in upgrading project. Actual operation results showed that the process performance was excellent. The COD removal was more than 60%. Effluent quality was better than the first level A criteria specified in the Discharge Standard of Pollutants for Mu- nicipal Wastewater Treatment Plant ( GB 18918 - 2002).
