摘　　要：研究了一种新型赤泥复合剂对太湖夏季水华原水、实验室培养海洋赤潮藻及模拟海水的絮凝除藻降浊性能。结果表明,赤泥复合剂具有良好的除藻降浊效果,对太湖水华藻去除率为97.3%,原水浊度去除率为95%;对海洋小球藻和三角褐指藻2种赤潮藻去除率分别高达99.1%和98.9%;对2种模拟海水的最高除浊率分别为96.3%和95.3%,其剩余浊度均低于4 NTU,从而为治理淡水水华与海洋赤潮提供一种新技术,同时为赤泥综合利用提供一种新途径。The removal of algal cells and turbidity from the raw water of Taihu Lake,the laboratory culture of marine algae and synthetic seawater using a novel red mud amelioration were studied.The results showed that excellent effects on algae and turbidity removal were achieved.For the raw water of Taihu Lake,97.3% of freshwater algae and 95% of turbidity were removed.The removal efficiency of marine Chlorella sp.and Phaeodactylum tricornutum Bohlin from the laboratory culture was 99.1% and 98.9%,respectively.The 96.3% and 95.3% the of turbidity was removed from the two kinds of synthetic seawater and the residual turbidity was less than 4 NTU.Therefore,the red mud amelioration supplies a new method for freshwater algal bloom and seawater red tide mitigation and a new way for the multipurpose utilization of red mud.
