[0038] A process for processing durene waste liquid comprises the following steps:

[0039] S1. Collect the durene waste liquid to avoid mixing with other wastewater to prevent the reaction from generating more complex pollutants. Use acid and alkali to adjust the pH of the waste liquid to 6-9 to reduce the corrosive and toxic effects in subsequent treatment. If the waste liquid contains oil or suspended matter, use flotation and sedimentation methods to remove it;

[0040] S2, under acidic conditions of pH 3, add Fe 2+ and H2O2, generating strong oxidizing hydroxyl radicals, decomposing durene into small molecular organic matter and H2O, Fe 2+ The concentration is 0.1-1.0 g / L, the amount of H2O2 added is adjusted according to the COD value, and the reaction time is 1-2 hours;

[0041] S3. Utilize the strong oxidizing property of ozone to directly decompose durene, improve efficiency through catalytic oxidation, control ozone dosage, use 10-50 g / m³ waste liquid and 30-60 minutes contact time;

[0042] S4. Under high temperature and high pressure greater than 374°C and greater than 22.1 MPa, the organic matter in the waste liquid is completely reacted with oxygen to generate CO2 and H2O, and the waste liquid after advanced oxidation is introduced into an anaerobic reactor, where anaerobic microorganisms are used to degrade small molecular organic matter to produce biogas. The temperature is 35-40°C, the pH is 6.8-7.2, and the residence time is 24-48 hours;

[0043] S5. Use activated sludge or biofilm methods to further degrade remaining organic matter. Use nanofiltration membranes to remove dissolved organic matter and salts from the wastewater. Use activated carbon to adsorb residual trace organic matter to ensure that the effluent meets the standards. Use ultraviolet light and sodium hypochlorite for disinfection to kill pathogenic microorganisms in the wastewater.

[0044] The working principle of Example 1 is as follows: first, pour the durene waste liquid into the cleaning tank 8 and let it stand for a specified time. At this time, the oil in the waste liquid floats on the top of the waste liquid. Then, start the first electric push rod 10 to make the movable adjustment frame 11 slide along the track plate 9, so that each suction pipe 14 moves to the liquid surface. Then, start the second electric push rod 17 to make the suction pipe 14 move downward and insert it into the liquid surface at a specified height. Through the extraction hose 15, it is connected to the external extraction pump so that each suction pipe 14 can slowly extract the oil layer floating on the liquid surface and discharge it. After the liquid is discharged, the third electric push rod 23 is started to lift the support bracket 22, thereby driving the motor 21, the lifting plate 19 and the screening and filtering frame 24 to rise, so that the screening and filtering frame 24 is lifted and discharged from the inside of the cleaning tank 8, and then the motor 21 is started to drive the lifting plate 19 to rotate a specified angle, so that the screening and filtering frame 24 is tilted, so that the larger impurities and debris intercepted and filtered inside the screening and filtering frame 24 slide from the inside of the screening and filtering frame 24 and are discharged into the inside of the discharge hopper 6, and are conveniently collected and processed after being guided by the discharge hopper 6;

[0045] After the pretreatment of the tetramethylbenzene waste liquid, the solenoid valve 12 is started to slowly discharge the tetramethylbenzene waste liquid from the inside of the discharge pipe 13 to the inside of the adsorption filter cartridge 28, so that the waste liquid flows slowly inside the adsorption filter cartridge 28 and stays inside the adsorption filter cartridge 28 for a sufficient time. The activated carbon particles 29 inside the adsorption filter cartridge 28 can fully adsorb and treat the waste liquid, and then the adsorbed liquid is discharged from the limit frame 30 to the inside of the reaction tank 5, and the pH of the waste liquid is adjusted to 6-9 using acid and alkali. When it is necessary to replace the activated carbon particles 29 inside the adsorption filter cartridge 28, the fourth electric push rod 25 is started to drive the movable fixed plate 27 to move along the adsorption filter cartridge 28, so that each adsorption filter cartridge 28 moves from the top to the outside of the reaction tank 5, and then the baffle plate 33 is pulled and discharged from the inside of the limit frame 30, so that the activated carbon particles 29 inside the adsorption filter cartridge 28 are discharged from the limit frame 30, making it easy to replace the activated carbon particles 29.

[0046] Example 2, based on Example 1, Figure 1 、 Figure 7 and Figure 8 As shown, an auxiliary discharge part 3 is provided inside the fixed support base 4 on the side facing away from the reaction tank 5. The auxiliary discharge part 3 includes a side panel 34, a discharge plate 35, a baffle adjustment plate 36, a second pull-out handle 37 and an auxiliary discharge groove 38. The side panels 34 are fixedly connected to both sides of the discharge plate 35. The auxiliary discharge groove 38 is opened through the top of the discharge plate 35. The baffle adjustment plate 36 is slidably engaged inside the bottom end of the discharge plate 35, and the baffle adjustment plate 36 is slidably engaged inside the auxiliary discharge groove 38. The second pull-out handle 37 is fixedly connected to the middle of the outer end of the baffle adjustment plate 36.

[0047] When implementing this embodiment, the side plates 34 and discharge plates 35 are provided to guide the activated carbon particles 29 discharged from the bottom of the limit frame 30 for centralized transportation and processing, so that the activated carbon particles 29 inside the adsorption filter cartridge 28 can be cleaned and replaced conveniently, and the discharged activated carbon particles 29 can be easily cleaned and centrally collected. Moreover, after the baffle adjustment plate 36 is pulled out by the second pull-out handle 37, the activated carbon particles 29 can fall from the inside of the auxiliary discharge trough 38, so that the collection frame provided below the auxiliary discharge trough 38 can facilitate the collection and processing of the activated carbon particles 29.

Use activated sludge or biofilm methods to further degrade remaining organic matter. Use nanofiltration membranes to remove dissolved organic matter and salts from the wastewater. Use activated carbon to adsorb residual trace organic matter to ensure that the effluent meets the standards. Use ultraviolet light and sodium hypochlorite for disinfection to kill pathogenic microorganisms in the wastewater.
