| 摘 要： | 采用K2FeO4预氧化复合高岭土和聚合氯化铝(PAC)混凝处理含藻和腐殖酸的混合水.结果表明,当藻浓度不变时,在一定范围内,随着腐殖酸浓度的升高,浊度、腐殖酸及藻去除率均逐渐下降.当腐殖酸浓度固定时,随着藻液浓度的升高,腐殖酸和藻去除率逐渐上升,而浊度去除率基本不变.同时考察了矿物高岭土投加量及目数、K2FeO4预氧化时间、不同污染物浓度比例对K2FeO4预氧化处理混合水效果的影响,当高岭土投加量为8 mg/L、粒径为140目时,浊度和腐殖酸、藻类的去除率分别为91.0%,80.9%和88.2%,投加量过大或目数过大,沉降性能变差,起不到良好的助凝作用.

| Abstract: | The water containing humic acid(HA) and algae was disposed by kaolin and poly aluminum chloride(PAC) pre-oxidized by K2FeO4.The results showed that the removal rate of turbidity,algae and HA decreased along with the increase of HA density to a certain extent when the density of humic acid remained constant.Under the constant HA concentration,the removal rate of HA and algae gradually increased and the removal rate of turbidity remained essentially constant with the increase of algae concentration.At the sam... |
