| 摘 要： | 在有机溶剂中合成了壳聚糖羟丙基三甲基季铵盐（HTAC），探索了最佳反应条件，得到了转化率较高、水溶性好的产品。该产品6mg／L与60mg／L的聚合铝复配，使孤一、孤五污水站污水浊度分别由90．4mg／L、64．0mg／L降到3．6mg／L、4．2mg／L。加入该产品40mg／L和聚合铝50mg／L，使孤二联污水油质量浓度由2706．8mg／L降到18．5mg／L．浊度由960mg／L降到4．4mg／L，絮凝净水效果十分显著。

| Abstract: | The most preferable synthesis process for hydroxypropyl-t rimethylammonium of chitosan(HTAC)in heterogeneous system is discussed.The obta ined quaternary ammonium salt of chitosan is soluble in water and characterized by IR.With 6 mg/L HTAC and 60 mg/L polyaluminium chloride(PAC) added together, the turbidity of wastewater of the 1st Gudao Water Treatment Plant decreases fro m 90.4 mg/L to 3.6 mg/L and that of the 5th Gudao Water Treatment Plant 64.0 mg/ L to 4.2 mg/L.With 40 mg/L HTAC and 50 mg/L PAC added togetheer,the oil content of wastewater of the 2nd Gudao Plant decreases from 2 706.8 mg/L to 18.5 mg/L a nd the turbidity of the wastewater from 960 mg/L to 4.4 mg/L. |
