Industrial wastewater treatment catalytic oxidation complete equipment

Abstract

The invention discloses industrial wastewater treatment catalytic oxidation complete equipment which comprises a catalytic oxidation reactor, wherein the catalytic oxidation reactor is internally provided with a catalyst reaction rack and a water distributor; a reactor sludge outlet is formed in the lower end of the catalytic oxidation reactor; the water distributor is connected with the outlet of a micro-filtering membrane purification device; a water inlet tube and a backwash water outlet tube are connected with the inlet of the micro-filtering membrane purification device; a water storage tank at the upper end of the catalytic oxidation reactor is connected with a settling pond dosing zone of a settling pond; a settling pond sludge outlet is connected with the bottom of the settling pond; a water generation tank at the upper end of the settling pond is communicated with a settling water generation tank; a backflow water tank and an effluent tank are arranged inside the settling water generation tank; the backflow water tank is connected with the outlets of the water distributor and the micro-filtering membrane purification device respectively; a generated water outlet tube is connected with the effluent tank. The equipment has the advantages that the structure is reasonable, catalytic oxidation is combined with the settling pond, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of industrial wastewater treatment, in particular to a complete set of catalytic oxidation equipment for industrial wastewater treatment. Background technique [0002] Catalytic oxidation technology is widely used in industrial wastewater treatment because it can efficiently degrade substances that are difficult to degrade by biological methods and can be applied to scenarios where microorganisms cannot be applied. [0003] At present, there is a common shortcoming in the catalytic oxidation reaction, that is, the surface activity of the catalyst cannot be effectively maintained for a long time during use. If it is desired to keep the catalyst surface active for a long time, it is necessary to increase the cleaning cycle of the reaction tank and the regeneration or replacement cycle of the catalyst, which brings about the problems of worker workload and wastewater treatment cost increase.
