摘要
采用活性污泥法和接触氧化两段工艺对高含盐的环氧丙烷生产废水进行处理,同时研究了不同水力停留时间的处理效果和不同的盐度对处理效果的影响。试验结果表明CODCr的去除率可以达84 38%,出水CODCr<160mg/L,pH<8。
A method of treating epoxy propane saponification wastewater with high salt content by activated sludge process followed (biological) contact oxidation process is introduced in this paper. It also researched the result of the experiment under different HRT and the influence of the change of salt concentration on the treatment.The result shows that total COD_(Cr) removal rate can reach 84.38%.The COD_(Cr) of effluent is below 160 mg/L and pH value is below 8.
