Neutralization | Scientific.Net

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.

Wastewater treatment sludge from a primary lead-zinc smelter is characterized as hazardous waste and requires treatment prior to disposal due to its significant arsenic and heavy metals contents. This study presents a method for the stabilization of arsenic sludge that uses a slag based curing agent composed of smelting slag, cement clinker and limestone.
