[0003] Publication No. CN215855834U discloses a sludge fermentation device for sludge composting treatment. The designed stirring assembly drives the stirring paddle to rotate through a driving motor, so that the stirring paddle stirs the sludge in the circular placement tray. The area stirred by the stirring paddle at one time covers the entire inner cavity surface of the circular placement tray, so that the sludge can be turned over and stirred at one time, thereby improving the turning efficiency and facilitating fermentation; the designed elastic plate helps to protect the inner wall of the circular placement tray and extend the service life of the circular placement tray.

[0004] However, the above-mentioned fermentation device for sludge composting treatment still has the following problems during actual use: although the sludge is assisted in fermentation by the stirring paddle inside the fermentation device, during actual operation, the compost liquid contained in the sludge evaporates during the stirring process, making it difficult to achieve the effect of compost reflux fermentation. Similarly, such fermentation devices are difficult to operate in a fully enclosed manner, and the odor in the sludge can easily cause pollution, affecting the treatment environment and the efficiency of sludge drying and fermentation.
