[0045] The working principle and usage process of this utility model are as follows: The raw water is controlled to enter the flocculation reaction zone 1 from the inlet 22 by the PLC integrated control module 14. In the flocculation reaction zone 1, the flocculation stirring system 2 is started to add chemicals to the raw water to produce flocs. At the same time, the return pump 12 recycles the clean water in the clear water zone 19 and sends it to the dissolved air tank 13. The air compressor 7 controls the air intake through the solenoid valve and reacts with the water in the dissolved air tank 13 to produce dissolved air water. The dissolved air water and the water effluent from the flocculation reaction zone 1 are evenly distributed into the tank through the lower water distribution pipe 8. The mixed water enters the separation zone through the U-shaped inclined plate 10. The U-shaped inclined plate 10 is distributed at a staggered angle of 60 degrees. When the particles in the liquid come into contact with the inclined plate, they sink along the inclined plate.

[0046] In the separation zone, if complex water quality is encountered, some flocs float to the surface through dissolved air water. The horizontal reducer in the sludge scraping system module 11 drives the gears at both ends through shaft transmission and sprocket transmission. The sludge scraper fixed on the customized chain scrapes the flocs that have passed through flotation into the sludge collection tank module 18, and then discharges them to the sludge tank through the end sludge discharge flange. At the same time, the flocs that do not float to the surface in the raw water mixed with dissolved air water in the separation zone are settled by the U-shaped inclined plate 10 and enter the sludge hopper device. The sludge is collected by the sludge hopper device and then discharged through the sludge discharge pipe 23, so as to achieve no dead corners and no accumulation.

[0047] The generated exhaust gas rises to the integrated gas collection hood 9, which has a gas collection hood outlet 15 at the top. The exhaust gas is discharged through the gas collection hood outlet 15. An observation hole is set on the hood to facilitate observation of the internal situation, ensuring safety, no hidden dangers, and no odor. The raw water, after passing through the separation zone, is collected from bottom to top through the end water collection pipe and enters the clear water zone 19 to ensure that there is no water residue. The clear water is controlled by the liquid level regulation system 16 to control the water level of the whole machine and discharge the clear water. The float in the liquid level regulation system 16 senses the water level change, and the liquid level controller controls the discharge of clear water according to the float signal to ensure the stability of the pool water level.
