硼泥复合混凝剂处理印染废水的研究

采用自制的硼泥复合混凝剂对所选择的若干水溶性染料水样和实际印染废水进行脱色试验，结果表明，混凝效果与染料种类，投药量，ｐＨ值，温度等因素有关，其中投药量范围在０．３￣０．６ｇ／Ｌ，ｐＨ适用范围为４．０￣１１．５，脱色率均可达９２％以上，在处理实际印染废水样时，仅投加０．３ｇ／Ｌ混凝剂时，其ＣＯＤ去除率达６７％以上，脱色率和ＳＳ去除率均达９８％以上，ｐＨ值也处于６￣９范围之内，并且比聚铝的处理效果好

Treatment of Dyeing Wastewater with Boron Sludge Composite Coagulant

?Some kinds of water samples containing water-soluble dyestuff and actual dyeing wastewater were treated with boron sludge composite coagulant (BSCC-I)- The results showed that the efficiency of coagulation was affected by some factors, such as dyestuff structure, coagulant charge amount, pH, temperature and so on. When coagulant charge amount is 0. 3~0. 6 mg/L and pH range is 4. 0~11. 5, decolorizational ratio of dyeing wastewater will be more than 92%.
