Description

Technical Field

[0001] This utility model relates to the technical field of denitrification devices, and in particular to a composite wastewater denitrification device. Background Technology

[0002] Nitrogen pollutants in wastewater, especially ammonia nitrogen and nitrate nitrogen, are one of the main causes of eutrophication. Eutrophication leads to excessive nutrients in the water, causing excessive algal blooms, which in turn affect water quality. The purpose of wastewater denitrification devices is to remove nitrogen compounds, mainly ammonia nitrogen and nitrate nitrogen, from wastewater to reduce eutrophication, protect the water environment, prevent water pollution, and meet discharge standards. Therefore, denitrification devices are a necessary part of compliant discharge from wastewater treatment plants.

[0003] Traditional denitrification devices are directly exposed to the external environment, so they do not have protective structures on both sides. Denitrification devices are often designed for high-pressure gas and liquid transportation. If workers accidentally touch the high-pressure pipes, it may cause spraying and leakage, which poses certain safety hazards. The efficiency of wastewater denitrification is poor and needs to be improved. Therefore, it is particularly important to design a composite wastewater denitrification device. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite wastewater denitrification device, comprising a base, a biological denitrification tank at the top of the base, an adsorption cylinder at the top of the base, a sedimentation tank at the top of the base, two arc-shaped blocks on each side of the base, a support shaft between the inner walls of two adjacent arc-shaped blocks, a support plate sleeved at one end of each of the two support shafts, an anti-contact plate at the top of each of the two support plates, and a reverse osmosis treatment cylinder at the top of the base.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a composite wastewater denitrification device:

[0022] Example 1:

[0023] like Figure 1-3 As shown, a composite wastewater denitrification device includes a base 1, a biological denitrification tank 2 on top of the base 1, an adsorption cylinder 3 on top of the base 1, a sedimentation tank 5 on top of the base 1, two arc-shaped blocks 6 on each side of the base 1, a support shaft 7 between the inner walls of two adjacent arc-shaped blocks 6, a support plate 8 sleeved at one end of each support shaft 7, and an anti-collision plate 9 on top of each support plate 8. A reverse osmosis treatment cylinder 4 is located on top of the base 1. The two anti-collision plates 9 are distributed on both sides of the base 1, which can shield and cover both sides of the base 1, enhancing the resistance of the base 1 to external forces. The structure set on top of the base 1 can be seen through the transparent cover 10, which also prevents the surrounding staff from accidentally bumping into the biological denitrification tank 2 and the sedimentation tank 5 and getting injured.

[0024] Example 2:

[0025] Based on Example 1, such as Figure 1 and Figure 4As shown, transparent covers 10 are fixedly installed inside the two anti-contact plates 9. Two locking holes 11 are opened on both sides of the base 1. A protrusion 12 is provided on one side of each of the four arc-shaped blocks 6. The two support plates 8 are fixedly sleeved to one end of the two support shafts 7 respectively. The bottom of the two anti-contact plates 9 is fixedly connected to the top of the two support plates 8 respectively. This utility model is a composite wastewater denitrification device. By setting up an adsorption cylinder 3, a reverse osmosis treatment cylinder 4, a sedimentation tank 5 and a support shaft 7, the support plates 8 are pulled outward, and the two protrusions 12 are gradually pulled out from the inside of the corresponding locking holes 11. Thus, the anti-contact plates 9 can be separated from one side of the base 1. The wastewater undergoes nitrification inside the biological denitrification tank 2. The ammonia nitrogen in the wastewater is converted into nitrate nitrogen. At this time, the biological denitrification tank 2 is supplied with sufficient oxygen.

[0026] Working Principle: Nitrogen pollutants in wastewater, especially ammonia nitrogen and nitrate nitrogen, are one of the main causes of eutrophication. Eutrophication leads to excessive nutrients in the water, causing excessive algal blooms, which in turn affect water quality. The purpose of wastewater denitrification devices is to remove nitrogen compounds, mainly ammonia nitrogen and nitrate nitrogen, from wastewater to reduce eutrophication, protect the water environment, prevent water pollution, and meet discharge standards. Therefore, denitrification devices are a necessary step for compliant discharge in wastewater treatment plants. Traditional denitrification devices are directly exposed to the external environment, so they do not have protective structures on both sides. Denitrification devices are often designed for high-pressure gas and liquid transport. If workers accidentally touch the high-pressure pipes, it may cause spraying and leakage, posing a certain safety hazard. The efficiency of wastewater denitrification is relatively poor and needs improvement. Therefore, it is particularly important to design a composite wastewater denitrification device. One end of each of the two protrusions 12 is sequentially embedded into the interior of the two locking holes 11, and the two are locked together, so that the base 1 and the support plate 8 can be installed. Two anti-contact plates 9 are distributed on both sides of the base 1. The base 1 is shielded and wrapped on both sides, which enhances its resistance to external forces and solves the problem of potential spraying and leakage caused by workers accidentally touching high-pressure pipes. The structure set on the top of the base 1 can be seen through the transparent cover 10, which also prevents workers from accidentally bumping into the biological denitrification tank 2 and sedimentation tank 5 and getting injured. Pulling outwards the support plate 8, the two protrusions 12 are gradually pulled out from the inside of the corresponding clip holes 11, so that the anti-contact plate 9 can be separated from one side of the base 1. The wastewater undergoes nitrification inside the biological denitrification tank 2, and the ammonia nitrogen in the wastewater is converted into nitrate nitrogen. At this time, the biological denitrification tank 2 is supplied with sufficient oxygen. The adsorption cylinder 3 is filled with activated carbon, which can adsorb nitrogen compounds in the water. The reverse osmosis treatment cylinder 4 can separate the nitrate nitrogen in the water through the permeability of the membrane. The sedimentation tank 5 is used to remove the precipitates produced in the reaction. The biological denitrification tank 2, adsorption cylinder 3, reverse osmosis treatment cylinder 4 and sedimentation tank 5 are all interconnected by pipes. When used together, they can realize composite wastewater denitrification and improve the wastewater denitrification efficiency of the device.
