【摘要】 研究了用超滤膜去除二级出水中的 COD、浊度、色度的性能。实验结果表明 :超滤膜对COD的去除率为 5 3 %以上 ,对浊度的去除率为 1 0 0 % ,对色度的去除率为 92 %以上。通过对不同操作压力下超滤膜的运行性能的比较 ,选择△P=0 .1 2 MPa作为最佳工作压力。并且建立了用超滤膜处理污水的凝胶层模型。对污染的超滤膜提出了有效、可行的清洗方法。更多还原

【Abstract】 Ultrafiltration membrane is employed for removal of COD ,turbidity and color in the secondary effluent The experimental results indicate that the mean removal rate of COD is over 53 %,the turbidity can be removed 100 %, and the color removal rate is over 92 % Compare with membrane operation functions of vary work pressure, the best operation pressure is selected(ΔP=0 12 MPa) The gel layer model which describe the removal of COD and the effective cleaning method for polluted membrane was presented更多还原
