摘要: This invention relates to a method for treating acidic waste water, particularly mine effluent, and solid water material useful the method. is obtained by solidifying mixture of rock wool an inorganic binder mainly containing at least one kind selected from silicates, hydroxides oxides alkaline earth metals alkali has porosity 50% or more. When brought into contact with iron ions sulfate ions, this can not only neutralize but also remove harmful heavy such as arsenic. Furthermore, it easy dispose spent material.
