摘要
针对设计规模105 m3/d的某污水处理厂需升级改造至GB 18918-2002一级A排放标准的工程,分析了面临的难题,认为主要是COD的达标。通过中试,验证了电磁(EM)催化臭氧氧化工艺对难降解有机废水深度处理的可行性。并在此基础上,进行了升级改造,实际运行结果表明,在进水COD平均为66.68 mg/L、O3投加量为20 mg/L时,EM催化臭氧氧化工艺可将COD降至平均为41.92 mg/L,平均去除率为36.4%。出水COD稳定达到GB 18918-2002一级A排放标准。
A WWTP with scale of 105 m3/d need to upgrade and reconstruct to meet the 1A discharge standard GB 18918--2002, the difficult problems were analyzed in this paper, the major problem is the concentration of COD can meet the standard. The feasibility of EM catalytic oxidation technology for refractory wastewater advanced treatment was proved through pilot. The project was upgraded and reconstructed based on the preVious project, and the results showed that, when the average concentration of COD in influent was 66.68 mg/L and O3 dosage was 20 mg/L, the average of COD could be reduced to 41.92 mg/L, the average removal rate was 36.4% through EM catalytic oxidation technology, and the COD of effluent could reach the 1A discharge standard GB 18918--2002.
