【摘要】 在高浓度硫酸盐制药废水的厌氧处理中,硫酸盐还原菌通过竞争性与非竞争性抑制影响产甲烷菌的活性和生长率。采用两段ABR-A/O组合工艺处理含高浓度硫酸盐制药废水。结果表明:系统稳定运行后,进水CODCr为10500～15000mg/L,SO42-为1000～1500mg/L时,CODCr、SO42-去除率分别达到98%和92%,出水各项指标均达到《污水综合排放标准》(GB8978—1996)二级标准。更多还原

【Abstract】 SRB (Sulfate Reducing Bacteria) affects the activity and growth rate of MPB (Methane Producing Bacteria) by rivalry and non-rivalry when pharmacy wastewater with high concentration sulfate was treated by anaerobic process. The combination of two-stage anaerobic baffled reactor and A/O were used to treat pharmacy wastewater with high concentration sulfate. When the system ran steady,the results showed that:the consistency of CODCr was 10 500 to 15 000 mg/L and SO2-4 was between 1 000 and 1 500 mg/L in the influent wastewater,the removal rate of CODCr and SO2-4 were 98% and 92%,and the effluent reach the second class of Integrated wastewater discharge standard (GB 8978—1996).更多还原
