摘要
在我国广大东北地区的水源大约3～4个月处于冰封期,这时水体处于低温低浊的状态,加之冬天这些地区补给水量小,引起水体中较高有机物含量,出现了东北冬季的低温低浊高有机物原水水质的特征。在水处理工艺中,低温低浊高有机物水仍旧是个难以解决的问题。利用膨润土的物理、化学性能,向水中投加膨润土,通过大量实验,确定最佳混凝剂、助凝剂及膨润土的投加量。有效解决了低温低浊高有机物水处理的难题。
In most regions of northeast China, water source is always kept in ice raying for about 3 --4 months when water remains in the state of low temperature and low turbidity, combined with the small amount of water supply in these regions which results in higher organic content in water in winter, so low temperature, low tur- bidity and high organic content, which is a difficult problem in the water treatment, has become characteristic of water in northeast China in winter. In this paper,by a large number of experiments, the optimum dosage of co- agulant, coagulant agent and bentonite poured into water is determined according to bentonite＇ s physical and chemical properties. So the problem of low temperature and low turbidity water treatment can be effectively solved.
