It is concluded by the research that: it is viable to achieve the proposed treatmentobjectives to the alga concentrated feeding water during the peaking summer season,such as, lower turbidity, control of residual aluminum and pH, equivalent performanceof pre-chlorination, only if dosing chlorine dioxide as pre-oxidation algaecide,ploy-aluminum as coagulant, HCA as flocculant, without the needs of modification toexisting water treatment facilities.

研究结果表明：在不改变现有给水处理设施的情况下，以二氧化氯作预氧化除藻剂，聚合氯化铝作混凝剂，高分子HCA作助凝剂，既可以有效降低水的浊度、控制水中余铝，又可以合理调节水的pH值，同时水中余氯还可以达到滤前加氯的效果，是处理夏季高藻期原水比较理想的工艺路线。

The method comprises the following steps: according to the raw water quality, the change of the number of bacteria inside the sedimentation tank and the water quality of the backflush yielding water, the backflush yielding water in the sedimentation tank is collected and deposited in a backflush phase of a working period; supernatant fluid containing mass active bacteria and soluble nutrient elements reflow to the sedimentation tank; total or partial sediment containing soluble nutrient elements in an underlayer reflow to the sedimentation tank and is reutilized by mass microorganisms in the sedimentation tank, thereby replenishing the nutrient substrate needed for microorganism growth, proliferation and metabolism under the condition of the low nutrition substrate, and maintaining the ecological stability in the sedimentation tank.

该方法根据原水水质和生物滤池内部细菌数量的变化以及反冲洗出水的水质，将生物滤池工作周期中反冲洗阶段的反冲洗出水收集并沉淀，将其含有大量活性细菌和溶解性营养元素的上清液回流至生物滤池，下层含有不溶性营养物质的沉淀全部或部分回流至生物滤池，被生物滤池当中的大量存在的微生物重新利用，从而补充在低营养基质条件下，微生物生长、增殖和新陈代谢所必需的营养基质，维持生物滤池当中的生态稳定。
