[0002] Existing biological methods for denitrification of wastewater are often traditional nitrification and denitrification process technology and anaerobic. Nitrification is the conversion of ammonia nitrogen in wastewater into nitrite nitrogen or nitrate nitrogen by nitrifying bacteria, and then the conversion of nitrate nitrogen in wastewater into nitrogen gas by denitrification. The nitrification process requires oxygen and energy to oxidize ammonia nitrogen, and the denitrification process consumes carbon sources, alkalinity and energy. However, there are some difficult-to-solve problems in the traditional nitrification and denitrification process technology in our lives: 1. The technical energy consumption of ordinary nitrification and denitrification process technology equipment is high, and the sludge concentration of the pool operation cannot be increased, resulting in unstable system operation; 2. The drainage device of ordinary nitrification and denitrification process technology equipment is easily blocked, which causes the system to be unable to operate normally. Utility Model Content

DETAILED DESCRIPTION

[0013] The utility model is further described below in conjunction with the accompanying drawings and some implementation methods.

[0014] exist Figure 1Among them, an efficient integrated treatment device for NR includes a device main body, and the device main body is a box body 1 with a hollow interior. It includes a pipeline layer 2 through which nitrogen-containing wastewater passes and a biological reaction layer 3 that directly converts ammonia nitrogen in the wastewater into nitrogen. The pipeline layer 2 and the biological reaction layer 3 are separated by a partition plate 103. The partition plate 103 is integrally formed with the box body 1. The partition plate 103 divides the box body 1 into upper and lower layers. The upper layer is the biological reaction layer 3, and the lower layer is the pipeline layer 2. The pipeline layer 2 is located at the bottom end of the box body 1. It includes an inlet pipeline 201 for nitrogen wastewater to enter and a water distribution pipeline 202 formed by multiple pipelines intersecting and communicating with each other in a "field" shape distribution. The "field" - shaped water distribution pipeline 202 can solve the problem of water distribution blockage causing the system to malfunction. The outlet end of the inlet pipeline 201 is fixedly connected to the inlet end of the water distribution pipeline 202. The outlet end of the water distribution pipeline 202 passes through the partition plate 103 and extends into the biological reaction layer 3. The wastewater enters the pipeline layer 2 through the inlet pipeline 201 and then is discharged into the biological reaction layer 3 through the water distribution pipeline 202. When the wastewater is in the biological reaction layer 3, the sealing ring 305 effectively prevents the wastewater from penetrating into the pipeline layer 2; The biological reaction layer 3 is located above the partition plate 103. It includes a biological filler layer 301 that improves the adhesion of microorganisms, an effluent weir 302 for discharging the degraded wastewater, and a reflux pipeline 303 for preventing wastewater from overflowing. The effluent weir 302 and the reflux pipeline 303 are respectively located on both sides of the box body 1. The inlet of the reflux pipeline 303 is communicated with the biological reaction layer 3, and the outlet of the reflux pipeline 303 is connected to the inlet pipeline 201. The degraded wastewater overflows to the next - level process structure through the effluent weir 302. When the valve 102 of the effluent weir 302 is not opened in time, the degraded wastewater is discharged into the inlet pipeline 201 through the reflux pipeline 303 for re - degradation after reaching the height of the reflux pipeline 303, and this cycle is carried out. A circular hole 101 for discharging nitrogen is provided on the upper end surface of the box body 1. The nitrogen generated during the reaction can directly overflow from the water surface and be released into the atmosphere through the circular hole 101.

[0015] In this embodiment, a pipeline opening 304 for the outlet of the water distribution pipeline 202 to pass through is provided on the partition plate 103. An inner side of the pipeline opening 304 is provided with a sealing ring 305 that wraps the water distribution pipeline 202 to prevent wastewater from penetrating from the biological reaction layer 3 into the pipeline layer 2. The wastewater is discharged into the biological reaction layer 3 through the water distribution pipeline 202, and the sealing by the sealing ring 305 can effectively prevent the wastewater from penetrating from the biological reaction layer 3 into the pipeline layer 2.

[0016] In this embodiment, valves 102 are provided on the outside of the water inlet pipe 201, the return pipe 303 and the water outlet weir 302. The water inlet pipe 201, the return pipe 303 and the water outlet weir 302 can be closed or opened by the valve 102. Generally, the valve 102 of the return pipe 303 is in a normally open state to prevent the treated wastewater from overflowing. When the treated wastewater reaches a certain height, the valve 102 of the water outlet weir 302 can be opened to allow the degraded wastewater to overflow to the next-level process structure through the water outlet weir 302.

[0017] In this embodiment, the biological filler layer 301 is a polyurethane filler with many micropores. Selecting a polyurethane filler with many micropores as a microbial carrier and increasing the sludge concentration in the equipment or pool can effectively increase the adhesion of microorganisms, thereby increasing the microbial concentration and thus improving the treatment efficiency of the sewage treatment equipment.

[0018] In this embodiment, the height of the return pipe 303 is higher than the height of the outlet weir 302 . The height of the return pipe 303 is the highest height at which the box 1 can store wastewater. When the height of the return pipe 303 is exceeded, the wastewater is discharged to the water inlet pipe 201 through the return pipe 303 .

[0019] In this embodiment, the box body 1 and the partition 103 are made of anti-corrosion materials, such as organic and inorganic coatings, fiberglass, rubber products, inorganic plates, etc., to prevent chemical substances from corroding the box body 1, the partition 103 and the pipeline.

[0020] In this embodiment, the control circuit of the utility model is a common circuit in the circuit field. The device of the utility model can be connected to an external power supply or a built-in battery through a power cord to provide power for the device. Technicians in the relevant technical field can implement it and will not be elaborated here.

[0021] During the specific implementation of the utility model: during use, wastewater enters the pipeline layer 2 through the water inlet pipeline 201, and then is discharged into the biological reaction layer 3 through the water distribution pipeline 202. When the wastewater is in the biological reaction layer 3, the sealing ring 305 effectively prevents the wastewater from penetrating into the pipeline layer 2. The polyurethane filler is used as a microbial growth filler, which can effectively improve the adhesion of microorganisms, thereby increasing the concentration of microorganisms, thereby improving the treatment efficiency of the sewage treatment equipment. The nitrogen generated during the reaction of the wastewater in the biological reaction layer 3 can directly overflow the water surface and be released into the atmosphere through the circular hole 101. The degraded wastewater overflows to the next-level process structure through the outlet weir 302. When the valve 102 of the outlet weir 302 is not opened in time, the degraded wastewater reaches the height of the reflux pipeline 303 and is discharged into the water inlet pipeline 201 through the reflux pipeline 303 for further degradation, thereby performing a cycle.
