Abstract:

Using the wastewater discharged from a stone machining plant in Pingdingshan as the target,the treatment effect of traditional coagulants and KMnO₄/FeSO₄ cooperating enhanced coagulation process has been contrasted and researched. The results indicate that using KMnO₄/FeSO₄ cooperating enhanced coagulation process for treating the wastewater,under optimum conditions,the treated wastewater turbidity is 6 NTU,turbidity removing rate 99%,and interface settling velocity reaches 1.55 cm/min. The water quality of treated effluent and settling efficiency are both higher than those of traditional coagulants. This shows that high turbidity wastewater could be treated by KMnO₄/FeSO₄ cooperating enhanced coagulation technique rapidly and effectively.

Key words: KMnO₄/FeSO₄, turbidity, enhanced coagulation

摘要：

以平顶山某石材加工厂排放的废水为研究对象，对比研究了传统混凝剂与KMnO₄/FeSO₄协同强化混凝的处理效果。结果表明，利用KMnO₄/FeSO₄协同强化混凝处理该废水，在最佳条件下，处理后废水浊度为6 NTU，浊度去除率达到99%，浑液面沉速可达1.55 cm/min，处理出水水质及沉淀效率均高于传统的混凝药剂。KMnO₄/FeSO₄协同强化混凝技术能快速有效地处理高浊度废水。
