With the development of Chinese industry, various types of chemical waste, and more and difficult to handle, and the high concentration of refractory organic wastewater treatment in recent years has been a hot topic in the field of wastewater treatment and difficulty, Pu Yan Wal Yun Environmental Through physical and chemical wastewater treatment technologies comprehensive research trials that set redox, electrochemistry, flocculation and physical adsorption on a new micro-electrolysis technology that can effectively deal with high concentration organic wastewater. The new iron-carbon fillers are formed by two high-temperature smelting technology into the hole made. Firstly, the high temperature smelting iron with carbon wrapped up as a shape, then use a secondary smelting temperature gap materials do gap, thus forming a new model of high porosity iron-carbon micro-electrolysis filler. The new iron-carbon fillers features: Micro-electrolysis - iron-carbon inner electrolysis packing characteristics: (1) the formation of the anode and cathode catalyst and high temperature smelting of iron and carbon integration, ensure that "galvanic" effect sustained effect. Not as physically mixed group with iron and carbon that is prone to separate the anode and cathode, the impact of the original cell reaction. (2) packing microporous structure formation by high temperature alloy smelting, large surface area, strong activity, not passive, not compacted, the ratio of the anode and cathode were different wastewater, wastewater treatment provides a higher current density and more good effect micro-electrolysis reaction, the reaction rate, the general pharmaceutical wastewater takes only 30-60 minutes, long-term stable and effective. (3) After the micro-electrolysis treatment of wastewater in water to form the original ecology of ferrous or ferric ions, better than conventional coagulation coagulant, such as ferric coagulant without plus, COD removal efficiency, and will not cause secondary pollution of water; (4) the role of a wide range of organic contaminants, such as: dual fluorine containing carbon double bond, nitro, halo structure in addition to the degradation of organic matter is difficult to have a very good degradation effects;
