Abstract:

Co ntrast of the flocculating effects of ordinar y flocculants used by oil refiner ies in China was made to treat wastewater containing oil and sulphur and developed mult i- function 931-type flocculant. Through ex periments, the relationship between the optimum adding doze of flocculant and its removal rate, with differ ent pH, the optimum circumstance treating wastewater containing oil and sulphur ar e so defined and necessary technolog y parameters for its industrial application are offer ed.

Key words: treatment of w astewater containing oil and sulphur, flocculation, flocculant, remo val rate

摘要：

通过实验室试验，对国内目前处理炼油厂含油、含硫废水常用混凝剂的混凝效果进行了对比，研制开发了931型多功能混凝剂，通过试验，探讨其在不同pH值时，药剂的最佳投量与去除率的关系，从而确定了处理含油含硫废水的最佳条件，为其工业应用提供了必要的技术参数。
