摘　　要：用氯化三甲基壳聚糖季铵盐作絮凝剂处理味精废水。壳聚糖季铵盐适宜的 p H值为 9～ 1 3,CODCr去除率 80 %以上 ,高浓度壳聚糖季铵盐絮凝效果优于低浓度 ,延长振荡时间能提高絮凝效果 。Trimethyl chitosan chloride quatemary ammonium as flocculant is used for waste water treatment in monosodium glutamate production. The suitable pH of chitosan quatemary ammonium is 9～13, and the COD Cr removal rate is over 80%; higher concentration of chitosan quarter ammonium is better than lower one in flocculent effect; flocculent effect can be raised by prolonging vibration time and flocculent effect can not raised obviously by adding flocculant aids.
