[0050] Working Principle: When using a farmland water utilization wastewater treatment device, the sewage pipe is first installed above the mixing chamber 1. Then, under the continuous stirring of the first mixing blade 101 and the second mixing blade 102, impurities in the sewage are agitated and suspended. As the liquid level baffle 308 enters the sedimentation chamber 2, the water flow rate decreases due to the liquid level difference. Heavier sludge continuously sinks into the first sludge tank 204 and the second sludge tank 205. The aeration pipe frame 8 installed at the bottom of the sedimentation chamber 2 introduces a large amount of air, and foam is continuously generated in the water. Aerobic bacteria begin to decompose some of the impurities in the water. The foam scraper 201 above the sedimentation chamber 2 continuously scrapes the floating impurities into the collection tank 305. The sludge in the collection tank 305 is continuously sucked into the fifth discharge pipe 302 by the auger 301 and falls into the sedimentation chamber. The water falls into the drainage trough 303, while the clearer water is discharged from the outlet 307 and enters the secondary sedimentation chamber 3 for further sedimentation. An external suction pipe is inserted on the right side of the secondary sedimentation chamber 3 to pump out the settled water, while the silt accumulated at the bottom enters the fourth silt pipe 306. At the same time, the silt in the first silt trough 204 and the second silt trough 205 is drawn into the silt collection chamber 7 through the first silt pipe 202 and the second silt pipe 203. In the silt collection chamber 7, the first piston 701 and the second piston 704 are pulled out at a constant speed under the drive of the transmission rod 403, continuously pulling out the silt in the first silt pipe 202 and the second silt pipe 203. Under the action of the belt connection, the universal joint 404 at the bottom of the silt collection chamber 7 drives the anti-silt frame 405 to rotate in a rectangle, continuously agitating the silt from the bottom and discharging it through the third silt pipe 304.
