Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment equipment, and specifically relates to a synthetic ammonia wastewater reuse treatment system. Background Technology

[0002] Ammonia synthesis wastewater reuse treatment systems are specialized treatment systems designed for wastewater generated during ammonia synthesis production. Currently, these systems still face some challenges in energy consumption and cost control, particularly in the treatment of high-ammonia-nitrogen wastewater, where common processes like stripping and ammonia stripping exhibit significant energy consumption issues. Stripping requires maintaining a high gas-liquid ratio to ensure efficient ammonia removal, leading to high power consumption for the blowers. Furthermore, steam heating is often necessary in winter to address the impact of water temperature on treatment effectiveness, further increasing energy costs. While ammonia stripping is highly efficient at removing ammonia-nitrogen, its high steam consumption per ton of water typically accounts for a large portion of the treated water volume, resulting in low heat utilization and persistently high energy consumption. In contrast, biological treatment processes offer greater advantages in energy consumption control. For example, short-cut nitrification and denitrification technologies achieve ammonia-nitrogen conversion through microbial action, eliminating the need for large amounts of steam or electricity to maintain reaction conditions, resulting in significantly lower operating costs compared to stripping and ammonia stripping processes. Although the energy consumption of stripping and ammonia stripping can be reduced by optimizing operating parameters, excessive adjustment can easily lead to incomplete ammonia nitrogen removal, making it difficult to achieve an ideal balance between energy consumption control and treatment effect. Therefore, a new structure is needed to solve the above-mentioned technical problems. Utility Model Content

[0018] 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.

[0019] Please see Figures 1 to 3As the first embodiment of this utility model: a synthetic ammonia wastewater reuse treatment system, including: a tank assembly and a treatment assembly. The tank assembly is equipped with a treatment assembly for treating wastewater. The tank assembly includes a tank body 100 and a tank cover 110. The tank cover 110 is sealed on the upper surface of the tank body 100. Pipes for water inlet and outlet are installed on the outer surface of the tank body. The treatment assembly includes a partition 200 for separating space and a treatment tank 240 for nitrification wastewater.

[0020] The tank body 100 has a cylindrical structure. The upper surface of the tank body 100 has an open design. A tank cover 110 is installed on the upper surface of the tank body 100. The pipe fittings include an inlet pipe 120, an outlet pipe 130, and an outlet pipe 140. The inlet pipe 120 is installed on the upper edge of the outer surface of the tank body 100. The outlet pipe 130 is installed below the inlet pipe 120 through the tank body 100.

[0021] On the other side of the tank body 100 away from the outlet pipe 130, an outlet pipe 2 140 is installed. The inlet pipe 120, outlet pipe 130 and outlet pipe 2 140 have the same structure. The inlet pipe 120 is connected to the external wastewater supply equipment. An oxygen generator 150 with a corrosion-resistant and waterproof structure is installed on the inner wall of the tank body 100. The generating end of the oxygen generator 150 is located at the bottom inside the tank body 100.

[0022] The oxygen generator 150 is connected to an external gas supply device through a pipeline. A baffle 200 is installed on the inner wall of the tank body 100. A gap is provided between the rear surface of the baffle 200 and the inner wall of the tank body 100. A processing tank 240 is installed in front of the baffle 200 through the tank body 100.

[0023] In use, the user first pumps wastewater into the tank body 100 through the inlet pipe 120 using external equipment. After the wastewater is pumped into the tank body 100 (the volume of the wastewater does not exceed the upper edge of the partition 200), the pumping is stopped, and the wastewater is then treated. After the wastewater enters the cavity formed by the inner wall of the tank body 100 and the rear surface of the partition 200, it can be allowed to stand for a period of time. Then, the user can open the valve on the outer surface of the outlet pipe 130 using an external pump to remove the sediment that has settled at the bottom of the tank body 100, thus preventing it from affecting subsequent treatments. After treating the wastewater and removing the sediment, the outlet pipe 130 is closed, and then the oxygen generator 150 is started to fill the settled wastewater with oxygen (0.5-1.5 mg / L), facilitating subsequent microbial treatment. The user can then activate the pump inside the cavity on the rear surface of the baffle 200 to pump the settled wastewater to the front surface of the baffle 200 (both the rear and front surfaces of the baffle 200 are equipped with waterproof pumps, along with pipes, to facilitate the extraction of wastewater to different areas for treatment. The installation location, working structure, and operating principle of the waterproof pumps and oxygen generator 150 need to be determined by the user based on actual conditions). (The specific selection process will not be elaborated here.) At this point, some wastewater will enter the containment cavity formed on the front surface of the baffle 200. Then, the wastewater will be treated by the microbial sludge at the bottom of the baffle 200. Since oxygen was introduced into the wastewater beforehand, the aerobic bacteria inside the microbial sludge will convert the ammonia nitrogen in the wastewater into nitrite. Then, the aerobic bacteria (ammonia oxidizing bacteria) inside the microbial sludge will adjust the pH in this environment to maintain the free ammonia in the water at a suitable concentration (0.6-1.0 mg / L). This inhibits nitrite oxidizing bacteria without affecting the work of ammonia oxidizing bacteria. At the same time, the sludge stays in the tank for 3 to 5 days. Then, the tank lid 110 can be opened to replace it, eliminating the slow-growing nitrite-oxidizing bacteria. The wastewater treatment time is 2-4 hours to prevent the reaction from over-processing. At this time, the proportion of nitrite generated should reach at least 90%, and more than 80% of ammonia nitrogen should be removed. (The above principle and steps are chemical reaction steps, and the specific working details and principles are common knowledge in the chemical field, so they will not be elaborated here.) During use, the external inlet and outlet water pipes facilitate the orderly control of water flow, ensuring the stability of the wastewater treatment process. At the same time, the oxygen generator 150 installed on the inner wall can efficiently supply oxygen to the aerobic biological reaction (nitrification process) inside the tank, promoting the degradation efficiency of pollutants such as ammonia nitrogen.

[0024] Please see Figures 1 to 3As a second embodiment of the present invention: based on the description in the above embodiments, a gap is further provided between the rear surface of the processing tank 240 and the front surface of the partition 200, a baffle 210 is installed on the rear edge of the upper surface of the processing tank 240, the height of the upper edge of the baffle 210 is lower than the height of the partition 200, and a storage box 220 is installed on the front surface of the baffle 210.

[0025] The upper surface of the storage box 220 is open, and the lower surface of the storage box 220 and the upper surface of the treatment tank 240 are provided with a perforated plate 230. Microbial sludge is provided at the bottom of the cavity between the partition 200 and the treatment tank 240, and a carbon source is provided inside the storage box 220.

[0026] During use, after the wastewater undergoes nitrification by microbial sludge to remove ammonia nitrogen, the user can use the principle of the first embodiment to pump the wastewater from the front of the baffle 200 (without pumping out the sludge; the installation height of the waterproof pump depends on the actual situation) into the treatment tank 240. The wastewater then passes above the storage box 220, through the carbon source (solid), and finally reacts inside the treatment tank 240 before being discharged through the outlet pipe 140. Because the wastewater first contacts the sludge (during the nitrification stage of biochemical treatment, the microorganisms in the sludge decompose pollutants such as ammonia nitrogen in the wastewater), and then the carbon source is added before entering the treatment tank 240, this process is denitrification. The microorganisms in the sludge first convert ammonia nitrogen into nitrate and nitrite, which then enter the treatment tank. During the treatment of tank 240, the added carbon source provides energy for the denitrifying bacteria, which reduce nitrates and nitrites to nitrogen gas (released into the air; at this point, the user can connect a pipeline to the treatment tank 240, allowing the nitrogen gas to be discharged through the pipeline, and then the user can treat the nitrogen gas). The final product discharged from the treatment tank 240 is wastewater that has been denitrified and purified, with a significantly reduced concentration of pollutants (especially nitrogen). At this point, the wastewater can be reused or discharged. During use, the dedicated treatment tank 240 provides a stable and controllable environment for the nitrification reaction, which is conducive to the enrichment and activity maintenance of functional microorganisms such as ammonia-oxidizing bacteria, improving the ammonia nitrogen degradation efficiency. At the same time, the overall structure makes the system more integrated, facilitating precise control of reaction parameters, and ultimately enhancing the treatment effect and reuse reliability of synthetic ammonia wastewater.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
