【摘要】 通过分散和活性染料染色废水絮凝处理实验,探讨聚合硫酸铁(PFS)的盐基度与其絮凝性能之间的关系.结果表明,在适宜的pH值和投加量条件下,聚合硫酸铁的盐基度在10%~16%时,絮凝效果较好,色度去除率为80%以上.当PFS盐基度为13.43%时,处理效果最好,色度去除率达95%.更多还原

【Abstract】 Through flocculation treatment of wastwater dyeing by dispersed and reactive dyestuff, the authors inquired into the relation between alkalinity of polymerized ferri sulfate (PFS) and flocculation performance. The results showed that, a good flocculation effect with more than 80% decoloration was obtained under the condition of appropriate pH value and input dosage and also 10%~16% alkalinity of PFS; the best effect with 95% decoloration was obtained wnder 13.43% alkalinity of PFS.更多还原
