摘要
乙烯裂解过程中排放的碱渣废水,含有较高浓度的硫化物和有机物,本研究针对大庆石化总厂排放的乙烯裂解碱渣,采用缓和湿式氧化工艺,使处理后的废水硫化物小于2 mg/L,并使COD去除率达到35%以上。
The ethylene decomposition process discharges the alkali dregs waste water, includes the high density sulfide and the organic matter. This research in view of Daqing Petrochemical works emissions ethylene decomposition alkali dregs, uses relaxes the wet oxidized craft, after causes processing the waste water sulfide to be smaller than 2 mg/L, and causes COD to remove rate achieves above 35%.
