Background
The iron-carbon micro-electrolysis technology is a good process for treating wastewater by using a metal corrosion principle to form a galvanic cell, and is also called an internal electrolysis method, an iron scrap filtration method and the like. The micro-electrolysis technology is an ideal process for treating high-concentration organic wastewater at present, and is also called as an internal electrolysis method. Under the condition of no power supply, the micro-electrolysis material filled in the wastewater generates a 1.2V potential difference to carry out electrolysis treatment on the wastewater so as to achieve the purpose of degrading organic pollutants, and iron is corroded to become bivalent iron ions to enter a solution as a result of reaction. Because of the coagulation effect of iron ions, the iron ions attract particles with weak negative charges in pollutants in an opposite way, and form stable flocs (also called iron sludge) for removal. Wherein iron with low potential is used as anode, carbon with high potential is used as cathode, and electrochemical reaction is carried out under acidic oxygenation condition.
