The existing cleaning methods are often cumbersome and time-consuming. In order to improve the mixing effect of sewage, large particle impurities in sewage need to be intercepted. Although the existing filtering methods can play a filtering role, it is not convenient to remove and clean the filter block. The problems existing in the above technology are that it is time-consuming to clean the inner wall of the aeration tank, the cleaning efficiency cannot be improved and the labor force cannot be reduced, and it is not convenient to remove and clean the filter block.

After the sewage enters the interior of the filtering box 601 through the filtering component 6, it will pass through the filtering block 602, and the filtering block 602 filters and treats the sewage, intercepting the large-particle impurities in the sewage, thereby reducing the large-particle impurities in the sewage and improving the mixing effect.

[0027] The working principle of the present utility model:

[0028] When sewage needs to be treated, the sewage is passed through the filter block 602 so that the filter block 602 intercepts and filters the large particles of impurities in the sewage. The large particles of impurities will flow obliquely in the front and rear directions due to the shape of the filter block 602, and then the sewage will enter the interior of the tank body 101.

[0029] The motor 201 is operated to drive the first gear 203 to rotate. The first gear 203 will move the belt 205 when rotating. The movement of the belt 205 will rotate the two second gears 204. The two second gears 204 will rotate the two stirring columns 206 and the multiple stirring rods 207. By injecting air into the two aeration pipes 3, the two aeration pipes 3 will inject air into the inside of the two stirring columns 206, and then the air will enter the inside of the sewage through the multiple air outlets 7, so that the multiple stirring rods 207 can inject gas into the sewage during the stirring process.

[0030] After the stirring is completed, the valve of the sewage outlet 102 is opened to discharge the liquid inside the pool body 101. After the liquid is discharged, the two lifting columns 802 are operated so that the output ends of the two lifting columns 802 drive the two lifting blocks 803 and move the support plate 804 upward, so that the support plate 804 drives the stirring device 2, the scraping component 5 and the fixed block 103 to move upward. After moving to the top, the two handles 503 can be pulled to drive the baffle plate 502, the two scrapers 501, the connecting piece 10 and the two cleaning cottons 11 to move to the right. The two scrapers 501 will move the pool body 10 1 The impurities adsorbed on the inner wall are scraped off, and the two cleaning cottons 11 will absorb the remaining impurities and move to the far right, so that it is convenient for the staff to clean the inside of the pool body 101. After removing the bolts fixing the connecting piece 10 and the baffle 502, the connecting piece 10 can drive the two cleaning cottons 11 to be removed and replaced. By removing the bolts fixing the connecting plate 605 and the filter box 601, the two clamping blocks 603 can be pulled to drive the connecting plate 605 and the filter block 602 to move upward and move out of the inside of the filter box 601, so that the filter block 602 can be cleaned.
