摘要/Abstract

摘要： 利用自主研制的粒化复合膨润土协同表面活性剂十六烷基三甲基氯化铵对模拟酸性靛蓝废水进行脱色处理，主要考察了粒化复合膨润土及表面活性剂投加量、振荡时间、pH值、温度、溶液初始浓度等对脱色效果的影响及粒化复合膨润土的再生利用效果，并根据试验现象分析了粒化复合膨润土在脱色过程中所起的作用。结果表明：溶液的初始浓度和pH值对脱色效果的影响不大而温度的影响较大；在合适的条件下，模拟废水的脱色率可达100%；粒化复合膨润土在脱色过程中的作用主要是使十六烷基三甲基氯化铵在原有脱色能力基础上又形成对酸性靛蓝较强的絮凝能力，从而显著改善脱色效果；粒化复合膨润土易于再生，反复使用次数可达4次。根据试验结果可知，采用粒化复合膨润土协同表面活性剂对印染废水进行脱色处理，不仅可获得优良的处理效果，还具有固液分离容易、表面活性剂用量少、二次污染风险低、粒化复合膨润土再生性能好等特点。

Abstract: A self-developed granular complex bentonite were cooperated with surfactant cetyltrimethylammonium chloride (CTAC) to decolorize indigo carmine simulated wastewater.The effect of dosage of granular complex bentonite and surfactant,length of time for oscillating,pH,temperature,initial concentration of indigo carmine simulated wastewater,etc.on decolorization rate was investigated,as well as recycling effect of granular complex bentonite,the function of which during decolorization was researched according to experimental phenomenon.The results showed that initial concentration and pH of indigo carmine solution had little effect on the decolorization rate while temperature can greatly affect decolorization.The decolorization rate of indigo carmine wastewater could be up to 100% under right conditions.Granular complex bentonite could enhance the flocculation of acid indigo carmine,which could significantly improve the decolorization effect.Granular complex bentonite could easily regenerate and be used for four times.Not only well treatment effect could be achieved,but also it owns the excellent characteristics of easy separation of solid and liquid,less dosage of surfactant,low risk of secondary pollution,easily regeneration for granular complex bentonite,etc.excellent characteristics could be achieved when granular complex bentonite is cooperated with surfactant CTAC for decolorization treatment.
