A sludge inlet pipe 8 for inputting sludge into the sludge storage chamber 6, a sludge discharge pipe 7 for discharging sludge in the sludge storage chamber 6, an air inlet pipe 9 for inputting gas in the sludge storage chamber 6 into the odor removal chamber 5, and an exhaust pipe 10 for discharging gas in the odor removal chamber 5 are provided on the sludge tank 2. A first valve 11 is provided on the sludge discharge pipe 7; a liquid adding pipe 27 for adding spraying liquid into the odor removal chamber 5 and a liquid discharge pipe 28 for discharging the spraying liquid in the odor removal chamber 5 are provided on the sludge tank 2. A second valve 29 is provided on the liquid adding pipe 27, and a third valve 30 is provided on the liquid discharge pipe 28; a liquid level sensor 26 for monitoring the height of the spraying liquid in the odor removal chamber 5 is arranged in the odor removal chamber 5; an operation port for replacing the biological deodorization filler 13 is provided on the sludge tank 2, and a sealing door 31 is hinged at the operation port.
[0025] The deodorization mechanism 3 includes a filter plate 12, a biological deodorization filler 13, and a spraying assembly 14. The filter plate 12 is arranged in the odor removal chamber 5, and the filter plate 12 is located between the air inlet pipe 9 and the exhaust pipe 10. The biological deodorization filler 13 is placed above the filter plate 12. The spraying assembly 14 includes a circulation pump 15, a water suction pipe 16, a shunt pipe 17, and a spraying pipe 18.

The spraying pipe 18 is arranged on the shunt pipe 17, and a spray head 19 is provided on the spraying pipe 18.
[0026] The stirring mechanism 4 includes a stirring shaft 20, stirring blades 21, and a motor 22. The motor 22 is arranged on the sludge discharge pipe 7. The stirring shaft 20 is arranged on the output shaft of the motor 22 and extends upward and rotates into the sludge storage chamber 6. The stirring blades 21 are arranged on the stirring shaft 20; a connecting rod 23 is arranged on the stirring shaft 20, a scraping plate 24 is arranged on the connecting rod 23, and the scraping plate 24 is in contact with the inner wall of the sludge storage chamber 6; a stirring rod 25 is arranged on the stirring shaft 20, and the stirring rod 25 is located in the sludge discharge pipe 7.
[0027] During specific use, sludge is added into the sludge storage chamber 6 through the sludge delivery pipe 8 for storage. Spraying liquid is added into the deodorization chamber 5 through the liquid adding pipe 27. The height of the spraying liquid in the deodorization chamber 5 can be monitored by the liquid level sensor 26 to ensure that the height of the spraying liquid is below the gas delivery pipe 9. The circulating pump 15 can pump out the spraying liquid in the deodorization chamber 5 and send it into the spraying pipe 18. Finally, the spraying liquid is sprayed onto the biological deodorization filler 13 by the nozzle 19. Spraying the spraying liquid onto the biological deodorization filler 13 can optimize the growth environment of microorganisms in the biological deodorization filler 13, improve the deodorization efficiency, and extend the service life of the filler.

The odor generated by the sludge enters the deodorization chamber 5 through the gas delivery pipe 9, then the odor passes through the filter plate 12 and enters the biological deodorization filler 13. After being deodorized and purified by the biological deodorization filler 13, the purified gas is finally discharged through the exhaust pipe 10, which is beneficial to reducing the environmental pollution caused by the odor emitted into the external environment along with the sludge discharge, thereby improving the environmental protection performance of the sludge storage tank.
[0029] In summary, this solution is provided with a deodorization mechanism 3. Through the deodorization mechanism 3, it is convenient to purify the odor generated during the sludge storage process and prevent the odor from being discharged from the sludge tank 2, resulting in environmental pollution. This solution is provided with a stirring mechanism 4. Through the stirring mechanism 4, it is convenient to stir the sludge to enhance the activity of internal molecules of the sludge, and thus can reduce the phenomenon of sludge precipitation.
