摘要:
为解决传统处理工艺难以将石化废水化学需氧量(COD)降至60 mg/L以下的问题,在生化处理装置后,增加了臭氧氧化—生物滤池耦合工艺,对某石化工业园区内废水进行深度处理,考察了该工艺对COD去除率和臭氧氧化效率的影响。结果表明:臭氧氧化—生物滤池耦合工艺提高了废水中大分子有机物被臭氧氧化降解的机率,平均COD去除率为63%,最高可达75%;出水COD稳定在30 mg/L以下,达到地方超净排放标准;臭氧氧化效率均值为1.1,远高于单独使用臭氧氧化工艺的。
Abstract:
In order to solve the problem that the chemical oxygen demand(COD) of petrochemical wastewater was difficult to be reduced below 60 mg/L by the traditional treatment process, the coupling process of ozone oxidation and biological filter was added to the biochemical treatment unit, and the wastewater in a petrochemical industrial park was further treated. The effects of the process on the COD removal rate and ozone oxidation efficiency were investigated. The results showed that ozone oxidation- biological filter coupling process improved the chance of oxidative degradation of macromolecular organic matter in wastewater by ozone, with an average COD removal rate of 63% and a maximum removal rate up to 75%. The effluent COD was stable below 30 mg/L, meeting the local ultra-clean discharge standard. The mean ozone oxidation efficiency was 1.1, which was much higher than that of the ozone oxidation process alone.
