| Abstract: | An inorganic and organic floccnlating agent is used to settle the white earth catalyst in washing workshops. The results show that the new compound agent has a good effect in the settlement. Its PH value is 7-11 ,the temperature is 30-70 ℃,and the settling time is 5 min,the best amount of the floccnlent is 6.03 g/L,the average mass concentration reduces from 5 460 mg/L to 180.4 rag/L, the removal rate of white earth is 96.6% and the water turbidity decreases from 1023FTU to 24. 1 FTU. |
