摘　　要：采用静态搅拌试验,研究了污泥回流比对污泥回流强化混凝工艺处理模拟低浊微污染水源水的影响。试验结果表明,在低、中、高三种腐殖酸质量浓度即3.75,8.75和13.75 mg/L下,污泥回流强化混凝工艺对浊度、UV254和CODMn的去除率均随回流比的增加呈现先升高后降低的趋势,这三个指标的去除率分别在50%,300%和300%回流比时达到最大值。The influence of sludge return ratio on sludge return enhance coagulation process was studied adopting static stirring test in order to treat source water with low turbidity and microcontamination. The test results indicated that the removal rates of turbidity,UV254 and CODMnwere increased at first and then decreased with the increase of return ratio when the low,medium and high concentration of humic acid were 3. 75,8. 75 and 13. 75 mg / L respectively. The maximum removal rates of these three indexes could be obtained when the return ratios were 50%,300% and 300%.
