摘　　要：在以引滦水为原水的饮用水常规处理工艺中,针对高藻原水采取了生物控制、预氯化、强化混凝、对过滤单元进行适当调整等几项措施。两年多的实际生产运行表明,这几项措施有效控制了高藻原水对生产工艺的影响,显著降低了藻类数量,使出水浊度保持在较低范围内(<0.3NTU),保证了良好的出厂水水质。Countermeasures such as biological control, prechlorination, enhanced coagulation, and proper adjustment of filtration unit were suggested in a conventional water treatment process by the Luan River water as source water. The practical operation for two years showed that these countermeasures could control efficiently the influence of high algae on the process, reduce the quantity of algae significantly and keep turbidity stably at low range （ 〈 0.3 NTU） , so that satisfied treated water quality could be reached.
