| 摘 要： | 研究了无机絮凝剂ＰＡＣ，ＰＳＡ，ＰＥＳ，ＭｇＣｌ２，ＣａＯ及其与有机高分子絮凝剂ＣＧＡ复全使用对两种不同工艺漂白废水的混凝处理特性，结果表明，水质１ＣＯＤｃｒ，ＡＯＸ去除率分别为６３．２％，４５．３％，水质２ＣＯＤｃｒ，ＡＯＸ去除率达７３．１￥％，５３．４％。化钙与碳酸钠具有相同的降解ＡＯＸ能力，硫离子在中性ｐＨ条件下可显著提高ＡＯＸ的去除率。

| Abstract: | This study examined the effects of flocculents PAC, PSA, PFS, MgCl2, CaO, CGA and their complex on removal of CODCr and AOX from two kinds of different pulp bleaching effluents. The result showed that removal rate of COD, AOX were 63.2%, 45.3% and 73.1%, 53.4%respectively. Sodium carbonate was as effective as CaO for reducing AOX, AOX reduction was considerably more remarkable in the presence of sulphide. The effect were supper when flocculents were used with combination, the way of flocculation pH dosing orders and stirring did effect on the result except temperature. The sludge with high thermal value could be recovered. |
