摘要
研究了4种聚铁絮凝剂去除铜绿微囊藻的效果,发现絮凝除藻效果最好的是HPFCS02;考察了水体pH的影响,同时研究了3种粘土矿物(滑石、海泡石和高岭土)的助凝作用,发现水体pH对HPFCS02的絮凝效果有明显的影响,产生最佳絮凝效果的pH是7.5～8.5。3种粘土矿物助凝效果最佳的是海泡石,当HPFCS02的初始投加量只能去除60%左右时,加载50 mg·L-1的海泡石能将其去除率提高到90%以上。
The effect of 4 kinds of HPFCs for the flocculation of the microcystis aeruginosa（MA） was investigated,in which HPFCS02 was found to be a best flocculation for the sedimentation of cyanobacterial cells.The pH effect was discussed,as well as three clay mineral（Talc,Kaolin and Sepiolite） promoting the coagulating process.It was shown that the flocculation efficiency of MA by HPFCS02 reached the maximum value at initial pH 7.5～8.5.Sepiolite showed a best promotion of coagulation process.When the quantity of MA was removed about 60% at initial HPFCS02 dosage,its removal rate can be raised to over 90% by adding 0.05 mg·L-1 sepiolite.
