摘要
采用电气浮工艺对富营养化水体进行处理,利用正交试验考察了极板间距、电流强度、反应时间和pH对电气浮去除富营养化水体中CODMn和Chl-a效果的影响。试验结果表明,电流强度是一个重要的影响因素。在电流强度为1.2A,极板间距为0.6cm,反应30min,对富营养化水体中CODMn和Chl-a的平均去除率分别为79.57%和88.4%。
Electro-flotation process was employed to treat the eutrophication water. The effects of opera- tional parameters including plate spacing, current intensity, electrolysis time and pH on CODMn and Chl-a removal efficiency were investigated by orthogonal test. The experimental results showed that the current strength is an important factor. The eutrophication water of CODun and Chl-a average removal efficiency were 79. 57% and 88.4% respectively at current strength 1.2A, space between the electrodes 0. 6cm and reaction time 30min.
