摘要
我国北方地区地表水大多数为夏季高藻、冬季低温低浊的微污染水源水,常规工艺对高藻、低浊的微污染水源水处理效果较差,而集气浮和过滤技术一体化的浮滤池工艺很好地解决了这个难题。该文分析了浮滤池工艺的原理,论述了浮滤池的演变过程及国内外应用实例,并总结了浮滤池的工艺优势及运行过程中的影响因素,最后展望了浮滤池工艺的应用前景。
Most of the surface water in northern China is micro-polluted with high algae in summer,low temperature and low turbidity in winter.Conventional process is less effective in the micro-polluted raw water of high algae and low turbidity treatment,while the problem was solved fairly by flotation-filter with both function of flotation and filtration.The theory of flotation-filter process,discussing the evolution and applications of flotation-filter,was introduced.It summarized the characteristics and influencing factors of the process.Finally,the future applications of flotation-filter process were prospected.
