处理低温低浊水的高效助凝剂——改性活化硅酸在实验室研制成功。为了进一步验证其净水效能,笔者在烧杯搅拌试验的基础上,先后在哈尔滨供水三厂和宾县水厂冬季低温低浊时期进行了生产性试验,并对其助凝效果进行了探讨。 Low-temperature, low-turbid water treatment of high-efficient coagulant-modified activated silicic acid was successfully developed in the laboratory. In order to further verify the efficiency of its water purification, the author conducted a productive test on the basis of the beaker agitation test in the low-temperature and low-turbidity winter conditions of the Harbin No. 3 Water Supply Plant and the Binxian Water Plant in winter, and discussed the coagulation effect.
