Advance in enhanced patterns and improvement measures of iron inner electrolysis

Iron inner electrolysis technology, based on iron scraps as anodic sacrificial materials and activated carbon as cathodic catalysis, can reduce many refractory contaminants in industrial wastewater including halogenated compounds, nitro-aromatic compounds, azo dyes and high-valence toxic metals. It has promising application prospect. The reaction process and mechanism of this technology are introduced. The reinforcement patterns of iron inner electrolysis, as well as their application situation in current industrial wastewater treatment are analyzed. The improvement measures for iron inner electrolytic reactors and packing are summarized to provide guidance for the settlement of some common technical problems during the operation of iron inner electrolysis such as clogging, short circuit and blind corner of the reactor, iron scaling, packing lost, etc. Finally, it is pointed out that the concrete reaction mechanism, kinetics and the ways of practical application should be further investigated.
