Description

Technical Field

[0001] This utility model relates to the field of water purification technology, specifically a nitrogen and phosphorus recovery tank for water purification. Background Technology

[0002] Nitrogen and phosphorus recovery tanks are facilities used to treat wastewater containing nitrogen and phosphorus compounds. Their main function is to remove nitrogen and phosphorus from water through physical, chemical, or biological methods, thereby preventing eutrophication and secondary pollution. Currently, nitrogen and phosphorus recovery technologies mainly employ chemical precipitation and activated sludge processes. Chemical precipitation involves adding chemical agents to precipitate dissolved phosphorus from the water. Activated sludge processes utilize microbial metabolism to remove ammonia and nitrate nitrogen. However, chemical precipitation is only effective for dissolved phosphorus and causes significant pollution, while activated sludge processes achieve less than 60% total nitrogen removal, leaving large amounts of nitrogen and phosphorus still discharged into the environment through drainage systems.

[0003] Therefore, it is necessary to propose a nitrogen and phosphorus recovery pond for water purification to solve the above problems. Utility Model Content

[0004] Technical problem to be solved: The purpose of this utility model is to provide a nitrogen and phosphorus recovery tank for water purification, so as to solve the problems of low efficiency and high pollution of existing nitrogen and phosphorus recovery as mentioned in the background art.

[0005] Technical Solution: To achieve the above objectives, this utility model is implemented through the following technical solution: A water resource purification nitrogen and phosphorus recovery tank includes a water tank. A partition I is fixedly installed inside the water tank, dividing the water tank into front and rear chambers. Partitions II and III are fixedly installed in the front chamber of the water tank, arranged in a cross shape, dividing the front chamber of the water tank into four treatment chambers: left front, left rear, right front, and right rear. Purification materials are provided in the rear chamber of the water tank and in the four treatment chambers. Two overflow ports are opened on the upper part of partition III, and the two overflow ports are symmetrically arranged on both sides of partition II. Water outlets are opened on the lower right of partition II and the lower left of partition I. A water inlet pipe is fixedly installed at the bottom of the left front treatment chamber, and a drain pipe is fixedly installed on the upper part of the rear chamber of the water tank.

[0006] Preferably, the inlet pipe is fixedly installed on the side wall of the treatment chamber away from the overflow port, and the drain pipe is fixedly installed on the right side of the rear side wall of the water tank.

[0007] Preferably, the purification material includes solidified carrier microorganisms, calcium peroxide, polyaluminum chloride, and polyacrylamide.

[0008] Preferably, the top of the pool is bolted to a cover plate, and an exhaust port is fixedly installed on the cover plate.

[0009] Beneficial Effects: Compared with existing technologies, this utility model provides a nitrogen and phosphorus recovery tank for water purification. This tank has a unique structure and is easy to use. Wastewater enters the left front treatment chamber through the inlet pipe. When the water level rises to a preset value, the water flows into the second treatment chamber through the overflow port on the upper part of partition III. Then, it flows through the four treatment chambers and the rear chamber in sequence, forming a circulating water flow path. Finally, it flows into the next treatment stage through the drain pipe on the upper part of the rear chamber. In this process, the purification materials—solidified carrier microorganisms, calcium peroxide, PAC, and PAM—participate in the reaction throughout. The solidified carrier microorganisms can maintain their activity even when not in operation, laying a solid microbial foundation for water purification. Calcium peroxide continuously supplies oxygen to the microorganisms and is non-toxic and harmless. PAC and PAM enhance the flocculation effect, improving the purification speed and quality.

[0010] This solution, through the ingenious arrangement of baffles, overflow outlets, and water outlets, extends the water residence time, allowing it to fully contact the purification materials, greatly improving the nitrogen and phosphorus removal rate, and significantly enhancing the water purification efficiency.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] Example 1: This Example 1 provides a water purification nitrogen and phosphorus recovery tank, which is a direct improvement on the existing nitrogen and phosphorus recovery tank. It has a unique structure. Please refer to [link / reference]. Figure 1-2 As shown, the system includes a water tank 1. A partition I2 is fixedly installed inside the water tank 1, which divides the water tank 1 into two chambers, front and back. A partition II3 and a partition III4 are fixedly installed in the chamber on the front side of the water tank 1. The partition II3 and the partition III4 are arranged in a cross shape, dividing the chamber on the front side of the water tank 1 into four processing chambers: left front, left rear, right front, and right rear.

[0016] Purification materials are provided in the chamber behind pool 1 and in the four treatment chambers. Two overflow ports 5 are opened on the upper part of partition III 4, and the two overflow ports 5 are symmetrically arranged on both sides of partition II 3. Water outlets 6 are opened on the lower right side of partition II 3 and the lower left side of partition I 2. The purification materials include solidified carrier microorganisms, calcium peroxide, PAC polyaluminum chloride and PAM polyacrylamide. The solidified carrier microorganisms can maintain microbial activity in the non-working state. Calcium peroxide is used as an oxygen supply agent. It is non-toxic and pollution-free and can slowly release oxygen to provide oxygen for specific microorganisms. PAC polyaluminum chloride and PAM polyacrylamide are inorganic flocculants to increase purification efficiency. A water inlet pipe 7 is fixedly installed at the bottom of the treatment chamber on the left front side, and a drain pipe 8 is fixedly installed on the upper part of the chamber behind pool 1. The water inlet pipe 7 is fixedly installed on the side wall of the treatment chamber away from the overflow port 5, and the drain pipe 8 is fixedly installed on the right side of the rear side wall of pool 1 to further increase the residence time of water in the chamber.

[0017] Working principle: When using this nitrogen and phosphorus recovery tank, water is first introduced into the first treatment chamber through the inlet pipe 7. When the water level reaches the preset height, it flows into the second treatment chamber through the overflow port 5 at the top of the first treatment chamber, and then into the third treatment chamber through the outlet 6 at the bottom of the second treatment chamber. Then, it flows into the fourth treatment chamber through the overflow port 5 at the top of the third treatment chamber, and then into the rear chamber through the outlet 6 at the bottom of the fourth treatment chamber. Finally, it flows into the next stage through the drain pipe 8 at the top of the rear chamber. The nitrogen and phosphorus recovery tank forms a porous structure through three partitions, and the overflow port 5 and outlet 6 make the water flow in a clockwise direction, increasing the residence time of the water in each chamber and improving the purification efficiency.

[0018] Example 2: The difference between Example 2 and Example 1 is as follows: Figure 2 As shown, a cover plate 9 is bolted to the top of the water tank 1, and an exhaust port 10 is fixedly installed on the cover plate 9. Through the design of the cover plate 9 and the exhaust port 10, the nitrogen gas generated by water purification can be discharged into the collection equipment through the exhaust port 10, thereby improving the utilization rate of resources.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
