摘　　要：味精废水经吹脱、稀释预处理 ,CODCr32 0 0mg/L、氨氮 170mg/L、总氮 40 0mg/L ,在CODCr负荷 0 6kg/m3 ·d下 ,接触氧化法和活性污泥法都能达到GB8978 96的排放标准。当负荷为 0 8kg/m3 ·d时 ,低浓度进水方式可以使出水CODCr接近处理目标 ,但出水CODCr排放总量增加。由于味精废水含有高浓度的硫酸盐 ,缺氧状态下 ,硫酸盐还原反应影响了反映硝化反应。味精废水自身碱度不足 ,必须投加充足的碱量 ,以避免硝化时 pH的下降。This paper described a research on treatment of monosodium glutamate wastewater with anoxic aerobic SBR.Two processes were applied here——contact oxidation and activated sludge.Under the load rate of 0.6kg COD Cr /m 3·d,both effluents met the national discharge standard (GB8978 96).Under load of 0.8kg COD Cr /m 3·d,the treatment goal could only be obtained by influent of lower concentration.Due to high concentration of SO 2- 4 and negative influence of sulfate reduction,denitrification is insufficient.It was also showed that monosodium glutamate wastewater lacked of alkalinity,so enough alkali should be added in order to prevent pH from falling down.
