This is not appropriate for the actual use of phenol-containing wastewater and thus greatly affects the quality of wastewater purification, which is related to the pollution effect on the environment after discharge. In order to solve the above problems, the inventors have proposed a high-concentration coal chemical phenol-containing wastewater treatment device. Utility Model Content

One end of each bolt 26 is threaded on the inner side of the movable block 23.

[0021] By adopting the above technical solution, the movable block 23 is inserted into the slide groove 24 and then fixed with bolts 26, thereby completing the installation of the card plate 19. After removing the bolts 26, the movable block 23 is removed from the slide groove 24, which facilitates the disassembly of the card plate 19 and makes it easier to maintain and repair the components on the card plate 19 in the future.

[0022] An electric heating ring 29 is fixedly installed inside the secondary chamber 18.

[0023] By adopting the above technical solution, the temperature inside the secondary tank 18 is increased by setting an electric heating ring 29, which effectively enhances the activity of wastewater purification.

[0030] Working principle: First, wastewater is poured into the primary tank 1 through the inlet pipe 27. The filter plate 11 filters the wastewater for oil and impurities. The filtered wastewater enters the lower part of the primary tank 1. Then, the first motor 14 is started to rotate the shaft 12, which drives the cross plate 13 to rotate. Simultaneously, the extractant is manually poured into the primary tank 1 through the L-shaped pipe 15 at regular intervals, allowing the extractant to fully circulate with the wastewater and extract phenolic substances. After the cross plate 13 stops rotating, the upper layer is the extract phase, and the lower layer is the raffinate phase. Then, the booster pump 17 is started to send the raffinate phase into the secondary tank 18. Activated carbon material is then manually added. The second motor 22 is started to rotate the rotating column 20, which drives the stirring paddle 21 to rotate, so that the raffinate phase and activated carbon are mixed again to adsorb phenolic substances. This achieves the treatment effect of extraction and adsorption of phenolic wastewater, and the wastewater is treated in a dual manner, resulting in higher quality wastewater purification and significantly reduced emission pollution. The movable block 23 is locked in the slide groove 24 and then fixed with bolts 26, thus completing the installation of the card plate 19. After removing the bolts 26, the movable block 23 is removed from the slide groove 24, which makes it easier to disassemble the card plate 19 and facilitates the maintenance and repair of the components on the card plate 19 in the future.
