Treatment method of acid drainage and acidic waste water treatment material

摘要

This invention regards the manner which treats acidic guttation and the especially pit guttation which contain the sulfate ion and the iron ion and the solid effluent treatment material which is used for that. This effluent treatment material can, the rock fiber and the alkaline earths metal or the alkaline metal the silicate, solidifying the blend of the inorganic binder which designates one or more of hydroxide or oxide as the main component, it is something where percentage of void is 50% or more. When this effluent treatment material and the acidic guttation which contains the iron ion and the sulfate ion are made to contact, not only neutralization of guttation, harmfulness of the iron content and arsenic etc the heavy metal can be removed. In addition, also treatment of the effluent treatment material after the using is easy.
