Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a high-efficiency backwashing nitrification filter device. Background Technology

[0002] In the field of wastewater treatment, nitrification filters are key equipment for achieving wastewater purification, playing a vital role in converting ammonia nitrogen into nitrate nitrogen. With increasingly stringent environmental protection requirements, higher standards are being set for the filtration efficiency and stability of nitrification filters.

[0003] However, during long-term operation, traditional nitrification filters gradually accumulate a large amount of impurities and microbial metabolic products on the surface of the filter media, leading to filter layer blockage and affecting filtration efficiency and treatment capacity. Existing backwashing methods mostly use simple water flushing, which has limited scouring force on the filter media and is insufficient to effectively remove stubborn impurities. Therefore, there is an urgent need to design a highly efficient backwashing nitrification filter device to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a highly efficient backwashing nitrification filter device to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency backwashing nitrification filter device includes a tank body. A flushing mechanism is provided on one side of the tank body. The flushing mechanism includes a water pump. A second pipe is provided on the top of the water pump. A gas-liquid mixer is provided at one end of the second pipe. An air pump is provided on one side of the second water pump. A third pipe is provided on the outer wall of the gas-liquid mixer. The gas-liquid mixer is connected to the air pump through the third pipe. A connecting pipe is provided at one end of the gas-liquid mixer. A flushing assembly is provided on one side of the connecting pipe. The flushing assembly includes a shell disposed inside the tank body. A plurality of branch pipes are disposed inside the shell. A plurality of nozzles are disposed on the outer wall of the branch pipes. A plurality of outlet pipes are provided on one side of the shell.

[0007] Preferably, the pool body includes a filtration pool, and a water storage pool and a storage pool are respectively provided on one side of the filtration pool, with the storage pool located at the bottom of the water storage pool.

[0008] Preferably, the filter tank is provided with a pipe, and the filter tank is connected to the water storage tank through the pipe.

[0009] Preferably, a water inlet assembly is provided on one side of the water storage tank. The water inlet assembly includes a water inlet pipe that connects to the water storage tank, and a valve is sleeved on the outer wall of the water inlet pipe.

[0010] Preferably, a water outlet assembly is provided on one side of the storage tank. The water outlet assembly includes a water outlet pipe that connects to the storage tank, and a water pump is provided at one end of the water outlet pipe.

[0011] Preferably, a filter assembly is provided on the top of the rinsing assembly, the filter assembly including a coarse filter layer, a fine filter layer and an adsorption layer.

[0012] In the above technical solution, the present invention provides a high-efficiency backwashing nitrification filter device, which has the following advantages:

[0013] (1) The water pump and air pump in the flushing mechanism work together with the gas-liquid mixer to fully mix the gas and liquid and then transport them to the flushing component through the connecting pipe. This makes the gas-liquid mixture sprayed from the nozzle form a strong and uniform flushing force on the filter material. Compared with single water flushing or air flushing, it significantly improves the backwashing effect and can thoroughly remove impurities and microbial metabolites from the surface and pores of the filter material, effectively prevent filter layer blockage, and ensure filtration efficiency.

[0014] (2) The filter assembly adopts a multi-layer composite structure. Through the cooperation of each layer, it not only ensures the effective interception of the backwashed material, but also avoids the excessive water flow resistance caused by too many filter layers, which affects the backwash efficiency. It achieves a balance between filtration effect and water flow smoothness, ensuring the stable operation of the entire filtration system while effectively protecting the quality of the effluent.
