| 摘 要： | 用吸附混凝-两段SBR法处理味精废水。吸附混凝试验先加入吸附剂（硅藻土或膨润土）吸附处理后投加聚丙烯酸钠（PAS）作为絮凝剂进行混凝处理，在温度40℃、pH3.0、吸附剂投加量为1.6g/L、PAS投加量为80～100mg/kg的条件下能取得较佳的效果，CODcr去除率在55%～65%，SS去除率在85%～94%之间。稳定运行的结果表明，两段SBR法CODcr去除率为94%～96%，NH4+-N去除率为82%～93%。

| Abstract: | A pilot study on Monosodium Glutamate (MG) wastewater treatmentwas conducted using adsorption and flocculation followed by two-stage Sequencing Batch Reactor (SBR). In pretreatment of MG wastewater, best removal efficiency was reached by adding bentonite (1.6 g/L) as adsorbent and sodium polyacrylate (100 mg/kg) as coagulant. the removal rates were 55%-65% for CODcr and 85%-94% for SS under the condition of 40 ℃,pH 3.0. The removal efficiency of CODcr and SS were 94%-96% and 82%-93% respectively by using two-stage SBR in steady stage. |
