| 摘 要： | 以原水中常见的微藻铜绿微囊藻(Microcysis aeruginosa)为目标物, 研究了聚合氯化铝(PAC)混凝除藻的效果及水中共存阴离子对混凝除藻的影响. 结果表明, pH为7~8时, 投加20 mg/L PAC剩余浊度降至0.80 NTU, 除藻率可达84.0%. 共存阴离子对混凝去除铜绿微囊藻的影响表现为: Cl－和H2PO4－对混凝除藻的抑制作用随着离子浓度的增加而增强, 最大可使除藻率分别降低47.6%和23.6%; SO2－4和HCO－3对混凝除藻的抑制作用随离子浓度的增加先增加后降低, 最大可使除藻率分别降低31.7%和50.2%; NO3－和F－对混凝除藻的影响较小.

| Abstract: | Microcysis aeruginosa,a general microalgae in source water,was selected to investigate the removal of algae by coagulation with PAC and the effects of co-existing anions in this process.Results showed that the residual turbidity was less than 0.80 NTU and the algal removal efficiency reached 84.0% with 20 mg/L coagulant dosage when the pH ranging from 7 to 8.The effects of co-existing anions on coagulation removal of Microcysis aeruginosa were as follows: The inhibition of Cl-and H2PO-4 on algal removal was... |
