The four process--neutralization/iron chipping micro-electrolysis/oxidation/coagulation were used to treat acidizing waste fluid. A new method of treating acidizing waste fluid with the neutralization/iron chipping micro-electrolysis/oxidation/coagulation was put forward. The optimal conditions of the treatment of single reaction are given.

Acid mine drainage, (AMD) typically has low pH and a large iron load along with other metals. The current approach to ,treatment, is an initial anoxic limestone ,treatment, for pH ,neutralization, with minimized iron armoring of the limestone, followed by aeration to precipitate iron (oxy)(hydroxide), which also tends to coprecipitate other metals.
