If ultra-fine coal dust inorganic solid particles can not be effectively removed in the coal-bearing sewage, it is not able to achieve the " zero discharge " in a true sense. Such sewage inevitably leads to serious pollution of the local water system. Electrical flocculation treatment technology for ultra-fine dust of inorganic solid particles is mainly used for coal pollution emission in large and medium-sized power plants and coal mines.lt solves the problems that it is difficult to separate the inorganic solid particles form ultra-fine coal dust and achieves the aim of zero emissions, energy conservation and cyclic utilization.%含煤污水如果对超细煤尘无机固体颗粒不能有效去除,就无法实现真正意义上的“零排放”,对当地水系造成污染.电化絮凝法用于超细煤尘无机固体颗粒的处理技术,主要应用在大中型发电厂、煤矿等煤水污染排放中,解决了超细煤尘无机固体颗粒难以分离问题,实现真正意义上的零排放,达到节能减排、循环利用的目的.
