Abstract: The influences of demulsifier dosage (A), coagulant dosage (B), pH (C), and reflux ratio (D) on the removal rate of suspended solids in mine water was investigated using the Response Surface Methodology (RSM). The results indicated that A, B, and D were significant main effects affecting the removal rate of suspended solids, while the interactions of AB, AD, BD, and CD were significant interactive effects. When the demulsifier dosage ranged from 600 mg·L -1 to 1 400 mg·L -1, the coagulant dosage ranged from 20 mg·L -1 to 100 mg·L -1, the pH ranged from 3 to 7, and the reflux ratio ranged from 20% to 100%, the removal rate of suspended solids varied between 81.14% and 98.65%. A multivariate linear regression was employed to establish the relationship between the various effects of the experimental factors and the removal rate of suspended solids, and the experiment was optimized. The optimal experimental conditions were found to be: demulsifier dosage of 1 199.92 mg·L -1, coagulant dosage of 40.47 mg·L -1, pH=4.19, and reflux ratio of 45.94%. Under above conditions, the theoretical removal rate of suspended solids reached 98.87%, which closely matched the experimental value of 98.46%.
