The invention discloses a double-effect electrolysis waste water treatment device. The double-effect electrolysis waste water treatment device comprises a direct-current power source, a water inflow pipe double-effect electrolysis reactor and an electrolysis catalytic oxidation reactor. The electrolysis catalytic oxidation reactor is connected with the cathode of a sodium hypochlorite catalytic oxidation reactor. The water inflow pipe double-effect electrolysis reactor is arranged on the cathode of the sodium hypochlorite catalytic oxidation reactor. The water inflow pipe double-effect electrolysis reactor is at least internally provided with one set of anodes and two sets of cathodes, the portion between the two adjacent sets of cathodes is filled with a sodium hypochlorite catalyst, the anodes are electrically connected with the negative electrode of the direct-current power source, and the cathodes are electrically connected with the negative electrode of the direct-current power source. Waste water to be treated enters the double-effect electrolysis reactor and then is subjected to electrolysis catalytic oxidation firstly, a certain amount of hypochlorous acid is generated while part of organic matter is removed, hypochlorous acid enters a hypochlorous acid catalytic oxidation bed layer along with the waste water, the organic matter prone to oxidation in the waste water is decomposed through hypochlorous acid under the effect of the catalyst, the burden on follow-up treatment is relieved, and stage treatment on the organic matter is achieved.
Description
technical field [0001] The invention relates to the technical field of electrolytic wastewater treatment, in particular to a double-effect electrolytic wastewater treatment device. Background technique [0002] With the rapid development of modern industry, the industrial wastewater produced not only increases in water volume, but also develops towards the trend of complex composition and high content of inorganic salts. At present, most of the industrial wastewater treatment processes at home and abroad adopt economical biological methods for treatment. However, with the increasingly stringent discharge standards in various places, it is difficult to meet the discharge standards only by biochemical treatment, especially high-salt and refractory wastewater. . [0003] Patent CN103539225A discloses an internal circulating fluidized bed electrocatalytic reactor and operating conditions for treating chemical organic wastewater. Ag-doped MnO loaded with stainless steel cathode...
