利用ABR-A-O组合工艺对洁霉素处理后的出水进行深度处理,对工程设计参数进行探索。结果表明,ABR、A、O停留时间分别为8、6、20 h,经混凝脱色后出水色度、悬浮物等指标均能达到发酵类制药工业水污染物排放标准(GB 21903-2008),COD、NH3-N达到当地环保部门补充要求,且运行效果稳定,费用较低。
The ABR-A-O combination process was applied to the in-depth treatment of inulin treated effluent to explore the engineering design parameters. The results showed that the residence time of ABR, A and O were 8, 6 and 20 h, respectively. The effluent chromaticity and suspended solids after coagulation decolorization could meet the discharge standards of water pollutants in the fermenting pharmaceutical industry (GB 21903-2008) , COD, NH3-N reach the supplementary requirements of local environmental protection departments, and the operation effect is stable and the cost is lower.
