Method for treating wastewater by cooperation of choking cavitation and H2O2

Abstract

The invention discloses a method for treating wastewater by cooperation of choking cavitation and H2O2. The method is characterized by being realized by adopting a process of treating the wastewater by cooperation of the cavitation effect generated by a choking cavitation unit consisting of a hydrogen peroxide storage box, a centrifugal pump and a choking cavitation device and strong oxidizing property of H2O2. The method comprises the following steps: feeding a solution of H2O2 into the centrifugal pump and the choking cavitation device while pumping the solution into the wastewater, generating the cavitation effect in the choking cavitation device, and forming strong shearing disturbance through micro jet flow and shock waves generated in a cavitation region, so that the area of contact between H2O2 and the wastewater is enlarged, the action time of H2O2 in the wastewater is prolonged, the probability of collision between H2O2 and organic molecules in the wastewater is increased, the degradation of the organic molecules in the wastewater is accelerated, the cooperative treatment effect of the choking cavitation and H2O2 is improved, and the purpose of degrading difficultly degraded components in the wastewater is achieved. Compared with the prior art, the technology has the advantages of simple process, convenience in operation, high energy utilization rate, strong adaptability, high efficiency, large treatment capacity, no secondary pollution, low cost and the like.

Description

technical field [0001] The present invention relates to a choked cavitation and Method for co-processing sewage. The method utilizes the cavitation effect produced by the sewage passing through the clogged cavitator and the coupling and synergistic effect of the mixed hydrogen peroxide to degrade the organic matter in the sewage and achieve the purpose of reducing the concentration index of the sewage. [0002] Background technique [0003] The composition of medical expenses is relatively complex. At present, there are about 2,000 commonly used drugs produced in our country. Different types of drugs use different types and quantities of raw materials, and the production processes and synthetic routes are also quite different. The quality and characteristics of wastewater produced by different types of drug production processes are also quite different. difference. Medical wastewater contains a variety of organic pollutants. These pollutants are generally toxic and diff...
