摘　　要：研究了酸改性粉煤灰对铜绿微囊藻及藻液中的溶解性有机物(DOC)的去除效果、影响因素及其对藻类生长的长期影响。结果表明,改性粉煤灰投加量为56 mg/L时,藻去除率达到92.4%;投加量为100 mg/L时,DOC去除率达到91.7%。藻液接近中性时去除效果最好,最小有效投加量与藻液初始藻含量呈正比例关系。同时研究了它对藻类活性的影响,投加量大于160 mg/L时,藻活性大幅下降。Removal of microcystis aeruginosa and dissolved organic carbon （DOC） with modified fly ash and its influencing factors were studied. The effect of modified fly ash on algae activity and algal growth over a long period of time was also tested. The removal rate of microcystis aeruginosa and DOC reached 92.4% and 91.7% when the dosage of modified fly ash was 56 mg/L and 100 mg/L respectively. The best removal rate could be obtained when pH of algae solution was near neutral. The minimum effective dosage was in proportion to the amount of initial algae cells in the algae solution. Meanwhile, the effect of the dosage of modified fly ash on algae activity was researched, and algae activity considerably decreased when the dosage was above 160 mg/L.
