摘要
宁波市梅林水厂日产水量４万ｍ３的生化池预处理姚江污染原水的生产实践表明：常温条件下氨氮去除率７０～９５％，有机物去除率达２０～３０％，浊度去除率５０～８０％，藻类去除率７８％以上。生化工艺比传统的混凝沉淀工艺对后续过滤工艺除污染效果具有强化作用，并可节省硫酸铝３０～５０％、液氯８０～８５％，具有显著的经济效益，同时提高了饮用水的安全性，降低了致癌的可能性。
Removals of ammonia-nitrogen,COD,turbidity and algae by a biochemical pond with a capacity of 4000m 3/d in Meining water plant,Ningbo City,for pretreating Yao River polluted raw water can reach over 70～95%,20～30%,60～80% and 78%,respectively,under the ordinary temperatures.As compared with the convntional coagulation sedimention one,the biological pretreatment process can save 30～50%,Al 2(SO 4) 3 and 80～85% liquid chlorine,and is favourable to the intensification of the following filter units work.It brings forth remarkable economical benefits,and can improve the safety of drinking water by reducing carcinogenic possibility.
