Description

Technical Field

[0001] The utility model relates to the technical field of sewage organic matter degradation, in particular to a device for removing refractory organic matter in sewage by an ozone catalytic oxidation process. Background Technique

[0002] Ozone catalytic oxidation is an effective method for removing organic matter in sewage. This method utilizes the strong oxidation ability of ozone. By reacting with the organic matter in sewage, organic acids, carboxylic acids and other intermediates are formed, and the organic matter is oxidized into inorganic substances for easy removal. The ozone catalytic oxidation method is applicable to the treatment of high-concentration organic wastewater.

[0003] In view of this, Chinese Patent No. CN208485658U proposes a device for removing refractory organic matter in sewage by an ozone catalytic oxidation process. An iron-manganese compound catalyst, a microporous water distribution pipe and a water outlet pipe extending to the outside of the main reactor are sequentially arranged inside the main reactor. The water inlet tank is connected to the microporous water distribution pipe inside the main reactor through a dissolved air inlet pipe on one side, and a pressure pump, a hydrogen peroxide water injector and an ozone water injector are sequentially arranged on the dissolved air inlet pipe, which has the positive effect of improving the sewage treatment efficiency;

[0004] When the above technical solution is implemented, since hydrogen peroxide and ozone are directly mixed and then introduced into the water tank and then the sewage organic matter is degraded by the catalysis of the catalyst during the process, in this process, hydrogen peroxide may not be completely mixed with ozone and then be introduced into the sewage, so that ozone is not completely strongly oxidized and then degrades the sewage under the catalysis of the iron-manganese compound, resulting in weak oxidation strength and reduced degradation efficiency. At the same time, the iron-manganese compound is generally a metal oxide, and when used as a catalyst and placed in sewage, it is easily covered by impurities therein, affecting its catalytic effect, and further reducing the effect of the device on degrading sewage organic matter. In view of this, this design scheme proposes a device for removing refractory organic matter in sewage by an ozone catalytic oxidation process. Content of the Utility Model

Detailed implementation mode

[0025] In order to more clearly illustrate the overall concept of the present invention, the following will be described in detail by way of example in conjunction with the specification drawings.

[0026] The embodiments are as follows:

[0027] The present invention provides a device for removing refractory organic matter in sewage by the ozone catalytic oxidation process as Figure 1-6 shown, which includes a sewage tank 1, a mounting frame 2, and a mixing mechanism 3 and a cleaning mechanism 4 respectively installed outside and inside the sewage tank 1, and the mounting frame 2 is fixed on one side of the sewage tank 1;

[0028] The mixing mechanism 3 includes a connecting frame 301, and one end of the connecting frame 301 is fixedly connected to one end of the mounting frame 2. An oxidant tank 302 is installed at one end of the connecting frame 301, and an ozone tank 303 is installed at the other end of the connecting frame 301. A first connecting pipe 304 is inserted through the bottom of the ozone tank 303, and one end of the first connecting pipe 304 is inserted and connected to the bottom of the oxidant tank 302. A second connecting pipe 305 is inserted through one side of the first connecting pipe 304, and a water pump 306 is installed at the upper end of the second connecting pipe 305. A mixing cylinder 307 is installed at the lower end of one side of the sewage tank 1, and one end of the second connecting pipe 305 is inserted and connected to the inner wall of the mixing cylinder 307. A stirring blade 308 is rotatably installed on the inner wall of the mixing cylinder 307, and the mixing mechanism 3 is connected and installed through the mounting frame 2 and the connecting frame 301, so that it can be relatively stable on the side of the sewage tank 1. At the same time, liquid injection ports that can be sealed and closed are provided on both the oxidant tank 302 and the ozone tank 303 to facilitate the injection of ozone water and hydrogen peroxide.

[0029] A motor 309 is installed at the top of the mixing cylinder 307, and one end of the stirring blade 308 passes through the top of the mixing cylinder 307 and is fixedly connected to the output end of the motor 309. A liquid inlet pipe 310 is inserted through the bottom of the mixing cylinder 307, and one end of the liquid inlet pipe 310 is inserted and connected to the inner wall of the sewage tank 1. A first sealing valve 311 is installed at the middle position on one side of the first connecting pipe 304, and a second sealing valve 312 is installed on one side of the liquid inlet pipe 310. Through the pumping of the water pump 306, ozone and oxidant can be quickly pumped into the mixing cylinder 307 for mixing reaction;

[0030] Further, the cleaning mechanism 4 includes a sealing plate 401 installed on the top of the sewage tank 1. A support plate 402 is installed at the middle position of the bottom of the sealing plate 401. A first sliding groove 403 is opened at the lower end on one side of the support plate 402, and second sliding grooves 404 are opened on both sides of the support plate 402. Both the first sliding groove 403 and the second sliding grooves 404 have a limiting effect, so that the movable handle 411 and the movable clamping plate 405 will not fall off;

[0031] Further, a movable clamping plate 405 is slidably arranged on the inner wall of the first sliding groove 403. A first spring 406 is fixedly arranged at the upper end of the inner wall of the first sliding groove 403, and one end of the first spring 406 is fixedly connected to the top of the movable clamping plate 405. A movable frame 407 is slidably arranged between the inner walls of the two second sliding grooves 404.

[0032] A fixing ring 408 is fixedly arranged at one end of the movable frame 407. Second springs 409 are fixedly arranged on both sides of the inner wall of the fixing ring 408. Scraping rings 410 are fixedly arranged at one ends of the two second springs 409. Both sides of the top of the movable frame 407 pass through the inner walls of the two second sliding grooves 404 and the top of the sealing plate 401 and are connected to a movable handle 411. Since the metal oxide will be consumed during the degradation process as a catalyst, the first spring 406 is used to squeeze the movable clamping plate 405, and at the same time the second spring 409 is used to squeeze the scraping ring 410 so that the movable clamping plate 405 and the scraping ring 410 are always in contact with the metal oxide, preventing it from falling off and the phenomenon that it cannot be cleaned because it cannot be touched during cleaning;

[0033] Further, a filter box 5 is installed below one side of the outer wall of the sewage tank 1, and the inner wall of the filter box 5 is communicated with the inner wall of the sewage tank 1. A filter plate 6 is inserted through the inner wall of the filter box 5. A drain pipe 7 is inserted through one side of the filter box 5. The filter box 5 is provided to further filter impurities through the filter plate 6 inside it, improve the degradation effect, and at the same time the filter plate 6 can be pulled out for cleaning and replacement.

[0034] A third sealing valve 8 is installed on one side of the drain pipe 7. A sealing box cover 9 is hinged on one side of the top of the filter box 5.

[0035] Working principle: When using the device for removing refractory organic matter in sewage by the ozone catalytic oxidation process in this design solution, hydrogen peroxide can be injected into the oxidant tank 302 and mixed with ozone to stimulate strong oxidizing property. Since the ratio of hydrogen peroxide to ozone is 1:1, when they are mixed, only a first sealing valve 311 is needed to control the opening and closing of its switch. Start the water pump 306 to extract and introduce hydrogen peroxide and ozone into the mixing cylinder 307 through the first connecting pipe 304 and the second connecting pipe 305. Then start the motor 309 at its upper end to rotate the stirring blade 308 to make hydrogen peroxide and ozone fully mixed and oxidized. Then open the second sealing valve 312 and enter the sewage tank 1 through the liquid inlet pipe 310, and catalyze and oxidize the organic matter in the sewage with the metal oxide therein as a catalyst to convert it into inorganic matter. Then, after filtering through the filter plate 6 in the filter tank 5, open the third sealing valve 8 and discharge it from the drain pipe 7. During this process, the movable handle 411 can be pulled regularly to make the movable frame 407 slide in the second chute 404, so that the fixed ring 408 drives the scraping ring 410 therein to lift and lower. And the metal oxide is placed at the bottom of the support plate 402 for support, and under the action of the first spring 406, it presses the movable clamping plate 405 to squeeze at its top, thereby fixing the metal oxide on the support plate 402. At the same time, the fixed ring 408 is outside it, and the scraping ring 410 always contacts the surface of the metal oxide under the action of the second spring 409. Pull the movable handle 411 to make the scraping ring 410 scrape on the surface, scrape off the impurities on its surface, so that after ozone and the like enter the sewage, the metal oxide can always play a good catalytic role and will not affect the overall effect of the device on the degradation of sewage organic matter, thereby improving the quality of catalytic oxidation of the device.
