复合型氨基葡聚糖絮凝剂的研制

STUDY OF COMPOSITION CHITOSAN FLOCCULANT

报道了一种复合型氨基葡聚糖絮凝剂的研究和制作过程，并将复合产品用来处理含Zn2＋15mg／L废水和含Cu2+30mg／L、Zn2＋15mg／L的混合废水，处理后水样中含Zn2＋、Cu2+浓度均低于GB8978－88中所规定的排放标准，其中Cu2+的去除率大于98％，Zn2+去除率大于95％，处理费用约0．2元／吨水．

The process of researding the composition chitosan flocculant and the method of making it are described in the article. When it is used to treat two kinds of contaminated water which contained either C= 15 mg/L Zn2+or C= 30 mg/L Cu2+and C= 15 mg/L ZnZ+. The conclusion of these experiments prove to be both at PH> 7. Cu2+and Zn2+in the water after treating are lowered to the drain levels accepted by GB8978 - 88 china. The expenses for treating is about zero point two yuan every a ton of the water.
