混凝沉淀-臭氧氧化深度处理皂素废水的实验研究

用混凝沉淀-臭氧氧化组合工艺对皂素生物处理出水的净化效果进行了研究。结果表明,YJD/PAM对皂素废水有较好的絮凝效果,臭氧氧化处理效果受废水pH、臭氧投加量、反应时间等因素的影响,实验的最佳反应条件为:废水pH值为11,臭氧投加量为1 500 mg/L,反应时间为20 min左右,此时出水COD和色度均达到国家排放标准。

Study on coagulation and ozonation in advanced treatment of diosgenin wastewater

Study on process of using coagulation sedimentation and ozonation to treat advanced treatment wastewater of diosgenin.The results indicate that YJD/PAM are efficient in coagulation of diosgenin wastewater,and pH,O3 dose and reaction time are important factors in ozonation of diosgenin wastewater.The optimal reaction conditions are as follows:pH of wastewater is 11,amount added of O3 1 500 mg/L,reaction time is 20 min,under this condition,COD and colourity of the effluent are lower than the national emission standard requirements.
