摘要
研究了混凝法处理二次废水的效果。利用正交实验确定混凝剂种类、混凝剂投加量、助凝剂投加量、pH四因素的影响;结果表明,混凝剂种类、投药量、助凝剂均为影响脱墨废水混凝效果的关键因素,PAC去除效果最好,混凝剂PAC投加量200mg/L,助凝剂PAM投加量3mg/L。
We researched result of coagulation treatment of secondary fiber papermaking wastewater. We De-termined influence of coagulant type, coagulant dosage, coagulant aid dosage and pH wtih the orthogonal exper-iment. The result showed that the key factors affecting deinking wastewater coagulation effect included coagu-lant type, coagulant dosage and coagulant aid. PAC had the best removal rate, coagulant dosage of PAC was 200mg/L and coagulant aid dosage of PAM was 3mg/L.
