摘要
选择聚合硫酸铁作为絮凝剂 ,羧甲基纤维素钠和壳聚糖作为助凝剂 ,进行了味精生产废水絮凝实验研究 ,确定了影响其工艺条件的主要因素。研究表明 :采用聚合硫酸铁作为处理味精离交尾液的絮凝剂 ,以羧甲基纤维素钠作为助凝剂 ,pH值的适应范围广 ( pH值5— 10 ) ,在适宜的条件下 ,COD去除率达 45 4%。采用聚合硫酸铁作为絮凝剂 。
The treatment of waste water of monosodium glutamate has been researched for years .It proved the waste water is very difficult to treat . To the proposed technology process, the paper choose the appropriate coagulant to experiment and experiment their influence factor. The research prove: To utilize Poly-Fe (PFS) as a coagulant to treat waste liquid of monosodium glutamate is very safety. When using sodium carboxymethylcellulose (CMC) as aid-coagulant, pH value may change from 5 to 10,under fit condition, COD can be removed 45.5% ..To utilize PFS as coagulant and use CMC as aid-coagulant to get rid of COD is a practical plan.
