摘要
我国寒冷地区的低温、低浊水难以处理,在对该地区某供水厂现有工艺进行分析的基础上,采用了强化处理技术,并比较了采用高锰酸盐复合药剂(PPC)作为助凝剂或活化硅酸作为助凝剂的优劣。结果表明,在浊度、锰、有机物的去除方面,助凝剂在各自的优化剂量下,PPC都较活化硅酸有明显的优势,可以明显降低生产成本,且PPC还可起到较好的强化过滤作用。
Low temperature and low turbidity water in the cold areas of China is difficult to treat. Enhanced treatment technology based on the analysis of the traditional treatment system of a water treat- ment plant in northern China was employed. A comparison between potassium permanganate composite （ PPC ） and activated silicate was made. The results showed that PPC was better than activated silicate in removing turbidity, manganese and organic compounds under optimized dose. The utilization of PPC can save production cost, and PPC plays the role of enhanced filtration.
