Embodiment 1

[0040]A device for continuously treating high-concentration organic wastewater with multi-stage runners, comprising: a wastewater processor with a cavity structure; a runner 7, which is vertically arranged inside the wastewater processor, and the inside of the runner 7 is filled with A wave-absorbing medium, the wave-absorbing medium is an activated carbon composite material loaded with metal oxides, and the metal oxides are Ni 2 o 3 , MnO 2 or Co 2 o 3 A mixture of one or more of them; the microwave generator 6 is respectively arranged at the top and bottom of the waste water processor.

[0041] The runner 7 is connected with the drive motor 5 to make the runner 7 rotate. The microwave generator is connected to the waveguide 8, and the waveguide 8 is connected to the waste water processor. The microwave energy is generated by the microwave generating device and transmitted to the waste water oxidation treatment equipment through the waveguide 8. It is used for the oxidati...

Embodiment 2

[0050] 1. Wastewater pretreatment: use a high-efficiency filter to filter out impurities and suspended particles in the wastewater, and adjust the pH value between 5-8, and add an appropriate amount of 30% hydrogen peroxide according to the initial measurement of wastewater COD and other indicators;

[0051] 2. Activated carbon pretreatment: configure a certain concentration of Ni 2 o 3 or MnO 2 or Co 2 o 3 Metal oxide solution, under the condition of stirring, add a certain weight of fruit shell activated carbon according to the proportion of the solution volume for impregnation, and then roast, the treated activated carbon is bundled with wire mesh, and the whole is put into the runner of the wastewater treatment equipment ;

[0052] After completing the assembly of the runner and the pretreatment of wastewater, it officially enters the microwave-induced catalytic oxidation process of wastewater

[0053] 3. Turn on the wastewater feed pump 1, inject it into the oxidatio...

Embodiment 3

[0062] The specific process of step 2 is: configure a certain concentration of Ni 2 o 3 , MnO 2 、Co 2 o 3 Metal oxide solution, under the condition of stirring, add a certain weight of fruit shell activated carbon according to the proportion of the solution volume for impregnation, and then roast, the treated activated carbon is bundled with wire mesh, and the whole is put into the runner of the wastewater treatment equipment .

[0063] Wherein, in step 6, the rotating speed of the runner is 25 r / d.

[0064] In step 9, the concentration of organic gas in the tail gas is 5PPM.

Abstract

The invention relates to a method and a device for continuously treating high-concentration organic wastewater through a multi-stage rotating wheel. The device comprises a wastewater treatment device with a cavity structure; the rotating wheel which is vertically arranged in the wastewater treatment device, wherein the rotating wheel is filled with a wave-absorbing medium, the wave-absorbing medium is an activated carbon composite material loaded with a metal oxide, and the metal oxide is one or a mixture of more of Ni2O3, MnO2 or Co2O3; and microwave generators which are respectively arranged at the top and the bottom of the wastewater treatment device. Continuous treatment of wastewater is realized through cooperation of the rotating wheel and the activated carbon composite material. The rotating wheel continuously performs the adsorption oxidation-desorption process of the wastewater so that the activated carbon composite material in the rotating wheel can be repeatedly used.
