外文摘要：0.5g/L of kaolin suspension was took as the sample for coagulation. The jar test was adopted to examine the effects of the Compound Bioflocculant (CBF) dosage, hydrogen ion concentration (pH) and the CaCl2 dosage as coagulation aid on the removal efficiency of turbidity. The experimental results showed that CBF had an effective performance with dosage of 4-5mg/L in the alkalescence environment. The optimal conditions for the removal efficiency of turbidity by CBF were the dosage of 4ml/L and pH of 7.5. CBF added coagulation aid(CaCl2) could play effect of flocculation. Adding 1.0ml/L of 10% concentration solution of CaCl2 could achieve the best flocculation effect. Temperature had minimal impact on the removal efficiency of turbidity, it indicated that the removal rate of turbidity at low temperatures was not obviously influenced.
