摘　　要：针对炼油污水厂浮选池浮渣的性质和特点,在传统方法的基础上进行了改进,分别采用投加氧化剂、电解质和调节pH值的方法强化浮渣的脱水性能.试验结果表明:强化絮凝更适合浮渣脱水,浮渣含水率分别比传统方法降低了2.81%、2.32%和3.90%,实现了浮渣减量化.Considering the characteristics of scum in petrol-chemical wastewater treatment plant, the methods were improved based on traditional approach. The methods of adding oxidant, joining electrolyte and adjusting pH value were used separately. The results show that strengthened flocculation is more appropriate. The moisture content of the scum was reduced by 2.81%,2.32% and 3.90%, respectively. The reduction of scum was achieved.
