Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a device for treating ammonia nitrogen wastewater. Background Art

[0002] With the rapid development and expansion of industries such as fertilizers and chemicals, the resulting high ammonia nitrogen wastewater has become one of the constraints on industry development. Modern society places great emphasis on environmental protection, and my country is gradually strengthening its efforts in water pollution prevention and control. In this process, the treatment of ammonia nitrogen pollutants has become increasingly urgent. Ammonia nitrogen pollution of water bodies is extremely serious; its discharge into water bodies leads to eutrophication and has toxic effects on aquatic organisms.

[0003] Currently, the treatment of ammonia nitrogen content in industrial ammonia nitrogen wastewater mostly involves water exchange or chemical spraying. However, water exchange consumes a large amount of water resources, and the discharged wastewater also pollutes the environment. Chemical spraying requires manual spraying on the water surface using sprayers, which is not only slow but also makes it difficult for the chemicals to contact the lower water layer, resulting in poor treatment quality. In view of the above, we will carry out technological innovation based on the existing ammonia nitrogen wastewater treatment devices. Utility Model Content

[0004] The purpose of this invention is to provide a device for treating ammonia nitrogen wastewater to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for treating ammonia nitrogen wastewater, comprising:

[0006] A treatment box, with a reagent tank placed on top of it, and a second electrically controlled valve connected to the bottom of the reagent tank. The bottom of the second electrically controlled valve is connected to a spray plate. Wherein:

[0007] An aerator is placed on the front side of the treatment box, and an aeration disc is installed at the bottom of the inner side wall of the treatment box. An air supply pipe connects the aerator and the aeration disc.

[0008] Preferably, the top of the processing box is uniformly provided with support columns, and the medicine box is located on top of the support columns.

[0009] Preferably, a water pump is placed on the left side of the treatment tank, and the outlet of the water pump is connected to a water supply pipe, the outlet of the water supply pipe being connected to the treatment tank.

[0010] Preferably, the inlet of the water pump is connected to a pumping pipe, and the inlet of the pumping pipe is connected to a filter bottom valve.

[0011] Preferably, a first electrically controlled valve is connected to the right side of the processing box, and a drain pipe is connected to the right side of the first electrically controlled valve.

[0012] Preferably, a water level sensor is provided on the rear side of the inner wall of the treatment tank, and a main controller is provided on the front side of the treatment tank. The main controller is electrically connected to the water pump, the aerator, the first electrically controlled valve, the water level sensor, and the second electrically controlled valve.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] This invention uses a water pump to input wastewater from the pool into the treatment tank. When the second electrically controlled valve is opened, the diluted nitrosamine solution in the reagent tank will flow evenly into the water in the treatment tank through the spray plate, thereby degrading the ammonia nitrogen in the water. At the same time, the aerator aerates the water through the aeration plate, which can quickly bring the diluted nitrosamine solution into contact with the water phase, thereby improving the ammonia nitrogen degradation efficiency. It can also increase the dissolved oxygen in the water, promoting the dissipation of ammonia nitrogen and other harmful substances from the water body, thus effectively improving the quality of ammonia nitrogen removal from the water.

[0015] This invention enables automated removal of ammonia nitrogen from ammonia nitrogen wastewater, effectively reducing the labor pressure on workers. Attached Figure Description

Detailed Implementation

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Please see Figure 1-Figure 3A treatment device for ammonia nitrogen wastewater includes a treatment tank 3, a reagent tank 1 is placed on top of the treatment tank 3, a second electrically controlled valve 431 is connected to the bottom of the reagent tank 1, a spray plate 43 is connected to the bottom of the second electrically controlled valve 431, an aerator 4 is placed on the front side of the treatment tank 3, an aeration plate 51 is fixedly installed on the bottom of the inner side wall of the treatment tank 3, and an air supply pipe 5 connects the aerator 4 and the aeration plate 51.

[0022] Support columns 2 are evenly fixedly installed on the top of the treatment box 3, and the medicine box 1 is fixedly installed on the top of the support columns 2.

[0023] A water pump 33 is placed on the left side of the treatment tank 3. The outlet of the water pump 33 is connected to a water supply pipe 34. The outlet of the water supply pipe 34 is connected to the treatment tank 3. The inlet of the water pump 33 is connected to a water suction pipe 35. The inlet of the water suction pipe 35 is connected to a filter bottom valve 36. The right side of the treatment tank 3 is connected to a first electrically controlled valve 31. The right side of the first electrically controlled valve 31 is connected to a drain pipe 32. The inlet of the water suction pipe 35 and the outlet of the drain pipe 32 are placed in the bottom of the water on both sides of the tank. The water entering the water suction pipe 35 can be filtered through the filter bottom valve 36. The water in the tank is pumped into the treatment tank 3 by the water pump 33 through the water suction pipe 35 and the water supply pipe 34.

[0024] A water level sensor 42 is fixedly installed on the rear inner wall of the treatment tank 3, and a main controller 41 is installed on the front of the treatment tank 3. The main controller 41 is electrically connected to the water pump 33, the aerator 4, the first electrically controlled valve 31, the water level sensor 42, and the second electrically controlled valve 431. The water level sensor 42 detects the water volume in the treatment tank 3. When the water in the treatment tank 3 reaches the maximum upper limit, the main controller 41 can stop the water pump 33 and control the second electrically controlled valve 431 and the aerator 4 to start working. The effect of quantitative chemical dosing is achieved by controlling the opening time of the second electrically controlled valve 431. When the system is opened, the diluted nitrosamine solution in the reagent tank 1 will flow evenly into the water in the treatment tank 3 through the spray plate 43 to degrade the ammonia nitrogen in the water. At the same time, the aerator 4 aerates the water through the aeration plate 51, which can quickly bring the diluted nitrosamine solution into contact with the water phase, thereby improving the ammonia nitrogen degradation efficiency. It can also increase the dissolved oxygen in the water, promoting the dissipation of ammonia nitrogen and other harmful substances from the water body. After the wastewater is treated, the first electrically controlled valve 31 is opened by the main controller 41, so that the treated wastewater is discharged back into the tank through the drain pipe 32. This process can effectively improve the water quality in the wastewater tank.

[0025] Working principle: The inlet of the pumping pipe 35 and the outlet of the drain pipe 32 are placed in the water on both sides of the pool. The water entering the pumping pipe 35 is filtered through the bottom filter valve 36. The water in the pool is pumped into the treatment tank 3 by the pump 33 through the pumping pipe 35 and the water supply pipe 34. The water level sensor 42 detects the water level in the treatment tank 3. When the water level in the treatment tank 3 reaches the maximum limit, the main controller 41 stops the pump 33 and controls the second electrically controlled valve 431 and the aerator 4 to start working. The quantitative dosing of the agent is achieved by controlling the opening time of the second electrically controlled valve 431. When the electrically controlled valve 431 is opened, the diluted nitrosamine solution in the reagent tank 1 will flow evenly into the water in the treatment tank 3 through the spray plate 43, thereby degrading the ammonia nitrogen in the water. At the same time, the aerator 4 aerates the water through the aeration plate 51, which can quickly bring the diluted nitrosamine solution into contact with the water phase, thereby improving the ammonia nitrogen degradation efficiency. It can also increase the dissolved oxygen in the water, promoting the dissipation of ammonia nitrogen and other harmful substances from the water body. After the wastewater is treated, the main controller 41 controls the first electrically controlled valve 31 to open, thereby discharging the treated wastewater back into the tank through the drain pipe 32. This cycle can effectively improve the water quality in the tank.
