Abstract

The invention discloses a method for degrading water pollutant by electrochemistry cathode motivated permanganate and a device thereof, wherein the method includes steps of filling to-be-treated sewage to an electrode reactor, and feeding electrolyte to make that the concentration of the electrolyte is 0.05M; feeding permanganate to make that the concentration of the permanganate is 1-100 miu m; then treating under the conditions that the permanganate concentration is 1-100 miu m and the charging current is 50-200 mA, and processing for 30-60 min, and then completing the degradation of the pollutant in the sewage. The method and the device apply electrochemistry cathode motivated permanganate, thus the permanganate generates middle rate manganese ion with strong oxidizing property, and can effectively oxidize and absorb organic matters and heavy metals in the water; the device is plated at the inner wall of a reaction wall and the plate wall of an overflow plate in the form of plating, the contact area between the sewage and the cathode electrode is increased, thereby improving the motivation activating rate of the permanganate, decreasing the metal usage and reducing cost.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a method and a device for stimulating permanganate to degrade pollutants in water by an electrochemical cathode. Background technique [0002] In recent years, more and more pollutants have entered the water body, and the types have become more and more complex, which has caused serious pollution to the water environment on which people live and has brought a great threat to the sanitation and safety of drinking water. The traditional water treatment process still has some problems in solving micro-pollution of water body, eutrophication of water body, persistent organic pollutants, high-concentration organic wastewater and removal of heavy metals. The characteristics of selective and thorough oxidation of pollutants in the environment have advantages in degrading organic pollutants in water, and the removal of heavy metals mostly depends on different adsorption. As a...
