序批式生物膜反应器处理味精废水运行参数优化

Research on parameter optimization of treatment for gourmet powder wastewater with sequencing batch biofilm reactor

采用悬浮填料序批式生物膜反应器,分析了填料填充率、曝气量、曝气时间等运行参数对污染物处理效果的影响,试验结果表明:悬浮填料的最优填充率为30%,最佳曝气量为0.75 m3/h,为保证出水CODCr达到排放标准,必须保证足够长的曝气时间。

The paper adopts the sequencing batch biofilm reactor of the floating media, and analyzes the influence of the operation parameter, in- cluding the filler filling rates, the aeration rate, and the aeration time, on the treatment effect of pollutants, proves by the test result that the opti- mal filling rate for the floating filler is 30% and its optimal aeration rate is 0.75 m3/h, so the aeration time should be guarantee in order to ensure the CODcr of the effluent meet the discharge standard.
