Abstract

The invention discloses an industrial wastewater circulating fluid bed automatic treatment device which comprises a wastewater Fenton oxidation reaction tank body, wherein the inside of the tank body is sequentially divided into a circulating water distribution region, a FeOOH crystallization region and a gas-water separation region from bottom to top. The device is characterized in that the tank body is a four-layer structure, the tank body is respectively provided with an internal anticorrosive layer, a thermal insulation layer, a heating layer and an external anticorrosive layer from inside to outside; a heater is arranged in the heating layer around the tank body; the tank body can be heated and insulated to ensure the oxidation reaction in the tank body to be performed at proper temperature; and a pH value automatic control system can automatically detect the pH value of the mixed solution in the circulating water distribution region and control the on-off state and dosing amount of a sulfuric acid dosing pump, thereby ensuring the oxidation reaction in the tank body to be always performed under proper pH value condition, and further ensuring the sufficient degree of the oxidation reaction.

Description

technical field [0001] The application relates to waste water treatment equipment, in particular to a circulating fluidized bed automatic treatment equipment for industrial waste water, which belongs to the technical field of engineering machinery. Background technique [0002] In industrial wastewater treatment projects in some special industries, it is difficult to achieve the expected treatment effect only by using traditional physical, chemical and biochemical methods. There is still a certain amount of refractory organic matter remaining in the wastewater, which cannot meet the requirements of environmental protection discharge. For this reason, it is necessary to further use strong oxidants to react with high-molecular organic matter in wastewater, and oxidize high-molecular refractory organic matter into small molecular substances, so as to improve their biochemical properties and facilitate the subsequent biological treatment technology to play a role.
