[0021] Working Principle: Open the relevant valves to inject the wastewater to be treated into the main treatment tank 1 through appropriate pipes until the appropriate treatment level is reached. Additive tanks 9 are symmetrically fixed near both ends of the top surface of the fixed top plate 8. Based on the wastewater composition and treatment requirements, the corresponding wastewater treatment additives are injected vertically downwards from the output pipe of the additive tanks 9 into the main treatment tank 1. Start the stirring motor 10 fixed at the center of the top surface of the fixed top plate 8. Its output end drives the stirring shaft 11 to rotate vertically downwards within the main treatment tank 1, thoroughly mixing the wastewater and additives. This ensures the additives are evenly dispersed in the wastewater, reacting chemically with pollutants and initially decomposing some of them. Then, activate the aeration device 14, whose generated gas enters the connecting pipe 15 through its output end. Multiple parallel connecting pipes 15 transport the gas to the bottom end, which is connected to the aeration pipe 21. The aeration pipe 21 is evenly arranged inside the movable inner frame 20, with aeration head structures on its outer side. Gas escapes from the aeration head structure, forming numerous tiny bubbles in the wastewater. This increases the dissolved oxygen content, providing ample oxygen for aerobic microorganisms and promoting their decomposition and metabolism of organic matter, further purifying the wastewater. Impurities and microbial metabolites gradually precipitate, forming sludge. When the sludge accumulates to a certain level, the cylinder 17 at one end of the start-up side assembly box 16 extends horizontally to push the sealing plate 19. The sealing plate 19 is then pulled out from the discharge port 18, opening the discharge channel. The sludge is discharged from the main treatment tank 1 through the discharge port 18. Simultaneously, the movable inner frame 20 can be removed from the horizontal snap-fit ​​point on the inner side of the main treatment tank 1 to clean and maintain the aeration pipe 21, preventing blockage and ensuring aeration efficiency. The discharge valve 4 near the bottom corner on the side of the main treatment tank 1 is then opened, allowing the treated wastewater to be discharged through the discharge pipe 5 for recycling or discharge to a designated area.
