Description

Technical Field

[0002] Industrial wastewater includes production wastewater, production sewage and cooling water, which refers to wastewater and waste liquid generated in the industrial production process, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water. There are many types of industrial wastewater with complex components. For example, electrolytic salt industrial wastewater contains mercury, heavy metal smelting industrial wastewater contains lead, cadmium and other metals, electroplating industrial wastewater contains cyanide and chromium and other heavy metals, petroleum refining industrial wastewater contains phenol, pesticide manufacturing industrial wastewater contains various pesticides, etc.

[0003] Since industrial wastewater often contains a variety of toxic substances, it pollutes the environment and has great harm to human health. Therefore, it is necessary to develop comprehensive utilization, turn harm into benefit, and take appropriate purification measures according to the composition and concentration of pollutants in the wastewater before it can be discharged.

[0004] The redox method refers to the redox reaction of pollutants in wastewater during the treatment process, which causes the pollutants to be oxidized or reduced, thereby converting them into new non-toxic and harmless substances to achieve the purpose of treatment.

[0005] Existing sewage is mostly oxidized by ozone during redox treatment. However, after the ozone is introduced into the redox chamber, the bubbles it produces will gradually float up. Therefore, the ozone has a poor contact effect with the sewage at the bottom during oxidation, resulting in the pollutants in the bottom sewage cannot be effectively oxidized, which is not conducive to subsequent reduction operations, resulting in poor sewage treatment effects.

[0048] The oxidation-reduction method for treating high-concentration toxic and harmful industrial wastewater uses the oxidation-reduction device for treating high-concentration toxic and harmful industrial wastewater as described above, and comprises the following steps:

[0049] Step 1: The sewage is transported to the inside of the redox tank 6 through the water inlet pipe 10, and the ozone is transported to the inside of the delivery pipe 7 and the ozone pipe 8 through the ozone generator 3. At this time, the one-way valve 9 is opened to allow the ozone to enter the redox tank 6 for oxidation. During oxidation, the delivery pump 1414 is started. The delivery pump 1414 extracts the sewage through the connecting pipe 1413 and the water pipe seat 1412, and transports it to the inside of the lifting tank 1427 through the connecting hose 1416 and the connecting seat 1417. As the sewage is extracted, the sewage is Water enters the output pipe bin 1428 and is discharged through the drain port 1420. During this process, the universal motor 1422 is simultaneously operated, so that the universal motor 1422 drives the receiving wheel to rotate, and then the connecting cable 1424 is reeled up through the reeling wheel 1423, so that the connecting cable 1424 pulls the rotating rod seat 1425 to rise, and then the rotating rod seat 1425 drives the lifting water bin 1427 to rise. As the lifting water bin 1427 rises, the outer limit ring frame 1419 thereof moves along with the spiral plate frame 1424. The spiral guide port 1418 on 405 rotates, thereby rotating the lifting water tank 1427, so that the sewage is discharged in a spiral shape while being lifted and discharged. When it rises to a certain position, the universal motor 1422 reverses, so that the connecting cable 1424 is relaxed, so that the reset spring 1426 pulls the connecting seat 1417 and the lifting water tank 1427 to reset, so that the lifting height changes back and forth to increase the internal sewage fluidity, and when the rotating rod seat 1425 drives the lifting water tank 1427 to rise, the connecting rope 1429 will be relaxed accordingly At this time, the torsion spring 1431 can drive the cleaning roller 1407 to rotate, so that the cleaning roller 1407 drives the cleaning soft plate 1408 to clean the surface of the filter baffle 1411, and when the rotating rod seat 1425 descends, it will pull the connecting rope 1429, so that the connecting rope 1429 drives the cleaning roller 1407 to rotate in the opposite direction, and the torsion spring 1431 is deformed, and at the same time, the cleaning roller 1407 drives the cleaning soft plate 1408 to clean the surface of the filter baffle 1411, ensuring the cleaning state until the oxidation is completed;

[0050] Step 2, after oxidation, start the electric telescopic rod 503, and drive the blanking disc 513 to rise through the electric telescopic rod 503, so that the blanking disc 513 compresses the pressure spring 511, so that the bellows 509 is compressed, and then the amount of reducing agent placed is adjusted. After adjustment, the reducing agent is placed inside the bellows 509, and then the driving motor 505 is started. The driving motor 505 can drive the rotating disk 507 to rotate, and then the rotating disk 507 drives the upper circular plate 508 to rotate. The upper circular plate 508 cooperates with the pressure spring 511 and the lower circular plate 510 to rotate the bellows 509 until it rotates to the blanking port. At this time, the reducing agent falls into the inside of the communicating bellows 512, and is then transported to the inside of the redox bin 6 through the adding pipe 501;

[0051] Step 3: When adding the reducing agent, the reducing agent enters the redox chamber 6 and falls on the annular plate frame 1301. At this time, the electric rod 1305 is started, and the power motor 1303 and the driving gear 1302 are driven by the electric rod 1305 to adjust the height until the driving gear 1302 is meshed with the gear 1. At this time, the driving motor 505 is started, and the driving motor 505 drives the driving gear 1302 to rotate, thereby driving the gear ring 1306 to rotate, and the gear ring 1106 is rotated, so that the gear ring 1106 is rotated. 306 drives multiple equalizing scrapers 1307 to scrape and evenly distribute the reducing agent, so that the reducing agent is evenly distributed, and then the electric rod 1305 is started again, and the driving gear 1302 is driven by the electric rod 1305 to engage with the gear ring 2 1310, so that the gear ring 2 1310 rotates, and then drives the connecting ring frame 1311 and the shielding plate 1309 to rotate, so that the reducing agent falls evenly into the sewage through the reduction port 1308 for reduction. After treatment, the sewage is discharged through the drain pipe 12.
