Description

Technical Field

[0001] This invention relates to wastewater treatment technology, specifically to a fluorescent scanning coupled electrodialysis optimized electro-Fenton wastewater treatment combination device. Background Technology

[0002] High-salt organic wastewater, such as pharmaceutical wastewater, saline-alkali land remediation wastewater, and landfill leachate, not only contains a large amount of salt (Cl... - SO4 2- Ca 2+ Na + High-salinity organic wastewater contains a variety of pollutants, including plasma and various organic pollutants, some of which even contain oils and toxic heavy metal ions. Direct discharge without treatment can cause serious pollution to soil, surface water, and groundwater. Recalcitrant organic matter is the main pollutant in high-salinity organic wastewater. Treatment methods such as flotation, evaporation, solidification, and coagulation only transfer recalcitrant organic matter, not remove the pollutants. In contrast, electrochemical oxidation utilizes the highly oxidizing active components in the solution to degrade organic matter into small-molecule intermediates or directly mineralize it. It offers advantages such as short reaction time, thorough oxidation, and ease of automation, making it a promising candidate for high-salinity organic wastewater treatment.

[0003] Electro-Fenton reactors efficiently degrade organic matter by generating highly oxidizing free radicals (•OH), making them a highly efficient method for treating organic wastewater. Continuous O2 exposure is both a necessary condition for the operation of an electro-Fenton reactor and a major source of operating costs. 2+ The HClO-based electro-Fenton method utilizes Cl- in high-salt wastewater to oxidize Cl- at the anolyse into the substrate HClO, which is then reduced at the cathode to produce Fe. 2+ The reaction produces oxide species Fe IV O 2+ It degrades organic pollutants, avoids exposure to O2, and has significant cost advantages.

[0037] Based on Example 1, please refer to Figures 1 to 5 As shown, a connecting frame 21 is fixedly connected to the outer surface of the feed pipe 13, and a scraper 22 is fixedly connected to the outer surface of the connecting frame 21.

The second drain pipe 35 is connected to the connecting mechanism, which is used to supply the filtered water blocked on the purification plate 33 into the second drain pipe 35. One end of the second drain pipe 35 is fixedly connected to a second treatment box 36 fixedly connected to the mounting plate 1. One side of the second treatment box 36 is connected to the Cl⁻ treatment tank 8 through a pipe and a water pump.

[0039] A first filter plate 41 is fixedly connected inside the second processing box 36. A second filter plate 42, which is fixedly connected to the second processing box 36, is provided below the first filter plate 41. A third filter plate 43, which is fixedly connected to the second processing box 36, is provided below the second filter plate 42.

[0040] The connecting mechanism includes a water inlet trough 51 opened on the purification plate 33, a third drain pipe 52 slidably connected in the water inlet trough 51, a spring 53 fixedly connected to the water inlet trough 51 via a connecting block on the outer surface of the third drain pipe 52, a connecting iron ring 54 fixedly connected to one side of the third drain pipe 52, an electromagnet block 55 fixedly connected to the outer surface of the first treatment box 31, and a water baffle plate 56 fixedly connected to the surface of the purification plate 33.

[0041] A cleaning plate 61 is slidably connected to one side of the first processing box 31. A cleaning brush 62 is fixedly connected to one side of the cleaning plate 61. A drive mechanism connected to the first processing box 31 is fixedly connected to one side of the cleaning plate 61. The drive mechanism is used to drive the cleaning plate 61 to reciprocate.

[0042] The drive mechanism includes a transmission column 63 fixedly connected to the cleaning plate 61, the transmission column 63 being slidably connected to the first processing box 31, and one end of the transmission column 63 being fixedly connected to a telescopic drive member 64 fixedly connected to the first processing box 31 via a connecting plate.

[0043] The transmission mechanism includes a second rotation drive 71 fixedly connected to the organic matter processing tank 9. The second rotation drive 71 is a servo motor, which is controlled by a PLC programming program. The servo motor can be controlled to rotate forward and backward and rotate at different angles.

[0044] A cleaning door is rotatably connected to the bottom of the first processing box 31.

[0045] When Fe in organic matter treatment tank 9 2+ When precipitates form in the wastewater treated by the HClO-type electro-Fenton reactor 15, the solenoid valve on the feed pipe 10 is closed, and the solenoid valve on the first discharge pipe 23 is opened. Water then enters the first treatment tank 31 through the first discharge pipe 23. The first discharge pipe 23 evenly distributes water onto the purification plate 33 through a horizontal pipe and its drainage holes. During drainage, the transmission mechanism simultaneously rotates the feed pipe 13, which in turn rotates the connecting frame 21. The connecting frame 21 then rotates the scraper 22, which cleans the precipitates adhering to the inner wall of the organic matter treatment tank 9 and lowers the tank, facilitating discharge from the feed pipe 13. Simultaneously, the electromagnet block 55 on the first treatment tank 31 is activated. The electromagnet block 55 generates magnetic force that attracts the connecting iron ring 54 on the third drain pipe 52, thus fixing the third drain pipe 52 to the second drain pipe 35. The water then enters the purification tank. Wastewater on plate 33 is blocked by multiple baffles 34 on the purification plate 33. At this time, the baffles 34 block larger sediments in the wastewater, achieving sufficient filtration of larger sediments. Then, the filtered water enters the third drain pipe 52 through the water inlet 51 on the purification plate 33. Then, the third drain pipe 52 enters the second treatment tank 36 through the second drain pipe 35. Then, the first filter plate 41, the second filter plate 42, and the third filter plate 43 in the second treatment tank 36 filter the wastewater layer by layer, achieving the filtration of smaller sediments in the wastewater. This achieves sufficient filtration and cleaning of sediments in the treated wastewater. At the same time, the multiple baffles 34 on the purification plate 33 filter larger sediments, effectively preventing rapid clogging of subsequent filter plates, improving the service life and stability of the filtration device. Finally, the filtered and cleaned wastewater is pumped into the Cl⁻ treatment tank 8 through pipes and a water pump for further treatment.

[0046] During the filtration process of the purification plate 33, after a period of filtration, when there are many impurities filtered on the baffle plate 34, the first rotating drive 32 drives the purification plate 33 to rotate counterclockwise. Before rotation, the electromagnet block 55 is de-energized, causing the third drain pipe 52 to retract under the force of the spring 53, preventing obstruction of the rotation of the purification plate 33. Then, the filter surface of the purification plate 33 that was just filtered rotates to the bottom. At this time, the electromagnet block 55 is energized again, attracting and connecting the other third drain pipe 52. At the same time, the purification plate 33 continues to purify and filter through the baffle plate 34 on the other side. Then, the telescopic drive 64 drives the connecting plate and the transmission column 63 to move back and forth. The transmission column 63 drives the cleaning plate 61 and the cleaning brush 62 to move back and forth. The cleaning brush 62 automatically cleans the sediment on the purification plate 33 and the baffle plate 34, thereby realizing the automated cleaning of the purification plate 33 and improving the purification effect and service life of the purification device.
