[0024] Specifically, during operation, the sludge scraper motor 6 and the conveyor motor 10 are turned on. Wastewater enters from the inlet 1 and passes through the screen 2. Larger waste is intercepted, and the preliminarily filtered wastewater enters the storage chamber 3. The sludge scraper motor 6 drives the sludge scraper drive wheel 4 to rotate. The sludge scraper 5 rotates with the sludge scraper drive wheel 4. Under the rotation of the sludge scraper 5, the water flow slows down, and some of the heavier sludge settles at the bottom of the storage chamber 3. The other part of the impurities is filtered by the filter plate 7. The sludge scraper 5 scrapes the sludge at the bottom of the storage chamber 3 and on the filter plate 7 toward the conveyor belt 9. The conveyor motor 10 drives the conveyor drive wheel 8 to rotate, and the conveyor belt 9 rotates with the conveyor drive wheel 8. The sludge moves with the conveyor belt 9 toward the sludge discharge port 11, and the filtrate flows from the wastewater pipe to the incinerator 21 to meet the needs of wastewater treatment.

[0026] Specifically, sludge falls into the sludge fermentation tank 12 through the sludge discharge port 11. The stirring motor 14 is turned on, and the stirring motor 14 drives the stirring plate to rotate via the stirring transmission box 13. When the sludge fermentation tank 12 is full, the rotating motor 17 is turned on, and the rotating motor 17 drives the tank frame 15 to rotate, replacing the sludge fermentation tank 12. While the sludge is fermenting in the sludge fermentation tank 12, the flue gas treatment system treats the exhaust gas generated from sludge fermentation and incineration of wastewater filtrate. After the sludge has fermented into fertilizer, the sludge fermentation tank 12 is rotated above the drying conveyor belt 18, the tank lid buckle is opened, the tank lid is pulled open, and the fertilizer falls onto the drying conveyor belt 18. The drying motor 19 drives the drying conveyor belt 18 to rotate, and the fertilizer moves forward with the drying conveyor belt 18, passes through the drying chamber for drying, and then enters the next process with the drying conveyor belt 18 to meet the needs of environmentally friendly sludge treatment.

[0027] Working principle: During use, turn on the sludge scraper motor 6 and the transport motor 10. Sewage enters from the inlet 1 and passes through the screen 2. Larger waste is intercepted, and the preliminarily filtered sewage enters the storage chamber 3. Under the rotation of the sludge scraper drive wheel 4 and the sludge scraper 5, the water flow slows down. Some of the heavier sludge settles at the bottom of the storage chamber 3, while the other part of the impurities is filtered by the filter plate 7. The filtrate flows from the sewage pipe to the incinerator 21. The sludge scraper 5 scrapes the sludge at the bottom of the storage chamber 3 and on the filter plate 7 onto the transport conveyor belt 9. The sludge moves with the transport conveyor belt 9 to the sludge discharge port 11 and falls into the sludge fermentation tank 12. Turn on the stirring motor 14, and the stirring plate starts to rotate. When the sludge fermentation tank 12 is full, turn on the rotating motor 17, rotate the tank frame 15, and replace the sludge fermentation tank 12. After the sludge is fermented into fertilizer, rotate the sludge fermentation tank 12 above the drying conveyor belt 18, open the tank lid, and the fertilizer is dried in the drying chamber and enters the next process with the drying conveyor belt 18.
