摘　　要：针对富营养化水源水含藻量高的特点,分别采用生物过滤、臭氧预氧化-生物过滤、高锰酸钾预氧化-混凝沉淀和混凝-气浮四种不同处理工艺,研究了各工艺对高藻水源水的除藻效果。结果表明：生物过滤预处理对原水中藻类的去除率介于58.55%~75.89%,平均去除率为69.04%;当臭氧投加量为1.5mg/L时,臭氧预氧化-生物过滤工艺对原水中藻类的平均去除率可达85%以上;在PAC投加量为15mg/L、高锰酸钾投加量为0.8mg/L时,高锰酸钾预氧化-混凝沉淀工艺可以取得90%以上的除藻率;混凝-气浮工艺的除藻率介于87.86%~94.18%,平均去除率可达90.68%。As there are high algae content in the eutrophic source water,the bio-filtration process,ozone pre-oxidation/bio-filtration process,potassium permanganate pre-oxidation/coagulation process and coagulation-flotation process are adopted to compare the algae removal.The results show that the algae removal rate by bio-filtration pretreatment process is ranging from 58.55% to 75.89%,and the average removal rate is 69.04%.With an ozone dosage of 1.5mg/L,the algae removal rate by pre-ozonation/bio-filtration process is over 85%.With a PAC dosage of 15mg/L and a potassium permanganate dosage of 0.8mg/L,the algae removal rate by potassium permanganate pre-oxidation/ coagulation-sedimentation process is more than 90%.The algae removal rate by coagulation/flotation process is between 87.86% and 94.18%,with an average removal rate of 90.68%.
