[0002] In recent years, my country's large-scale poultry farming industry has developed rapidly and its scale has continued to expand. For a long time, poultry farming enterprises have only pursued economic benefits, with weak environmental awareness and outdated methods for treating manure and sewage. This has resulted in a large amount of high-concentration organic wastewater being discharged into rivers and lakes, causing continuous deterioration of water quality. Among these issues, the high concentrations of nitrogen and phosphorus in the wastewater are the main causes of eutrophication.

[0035] Reference Figure 1 The outer surface of the second treatment chamber 2 is provided with a drain valve pipe 26. There are three drain valve pipes 26 in total. The three drain valve pipes 26 are respectively connected to the inside of the biological filtration chamber 10 and the microbial aeration and decomposition chamber 11.

[0036] Working Principle: During operation, wastewater requiring treatment is introduced into filter cartridge 6 through wastewater inlet pipe 9 for initial filtration and slag removal via solid-liquid separation. The treated wastewater is then pumped to the microbial aeration and decomposition chamber 11 via the first liquid pump 12. Oxygen is supplied to the aeration plates 14 within the chamber via aeration generator 13 and air supply pipe 15. Mechanical stirring by the stirrer 18, driven by the stirring motor 17, dissolves oxygen from the air into the water, efficiently promoting microbial reproduction and activity. Aerobic microorganisms decompose organic matter in the wastewater. The wastewater quality in the microbial aeration and decomposition chamber 11 is monitored in real-time by the first water quality sensor 19 until it reaches compliant values. Then, the water is pumped to the biological filtration chamber 10 via the second liquid pump 20, where the biological filter 21 separates ammonia nitrogen and nitrite from the water. After the wastewater quality in the biological filtration chamber 10 is monitored in real time by the second water quality sensor 22 and reaches the compliant value, the treated water is transported to the disinfection chamber 3 by the third liquid pump 23. The ultraviolet sterilizer 24 in the disinfection chamber 3 uses ultraviolet radiation to kill bacteria and viruses in the wastewater, and then discharges it through the drain valve pipe 25. When the equipment needs to be cleaned, the slag scraper on one side of the conveying pipe can scrape the intercepted material on the inner wall of the filter cartridge driven by the transmission mechanism to clean it. The material accumulates and enters the conveying pipe through the slag inlet. The screw lifter driven by the conveying motor lifts the cleaned material of the filter cartridge to the slag discharge pipe for discharge, realizing the automatic cleaning and slag discharge of the filter cartridge. Liquid is passed through the auxiliary agent addition pipe 16 and the slotted opening of the disassembled biological filter 21 to flush the microbial aeration decomposition chamber 11 and the biological filtration chamber 10. The flushing waste liquid is discharged through the sewage valve pipe 26.
