Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a device for purifying and reusing aquaculture wastewater. Background Technology

[0002] With the rapid development of aquaculture towards intensification and large-scale operations, the amount of wastewater discharged during the aquaculture process has increased significantly. This wastewater not only contains a large amount of suspended particulate matter, but also accumulates pollutants such as ammonia nitrogen, nitrite, and phosphate. If it is directly discharged into natural water bodies, it can easily cause environmental problems such as eutrophication and ecological imbalance, and also cause serious waste of water resources. Therefore, efficient aquaculture wastewater purification and reuse technology has become a key requirement for the sustainable development of the industry.

[0003] Currently, existing aquaculture wastewater treatment devices still have some areas for improvement in practical applications:

[0004] Firstly, in the filtration stage, traditional devices mostly adopt a single filtration channel design. When the filter media needs to be replaced or maintained due to excessive adsorption of impurities, the operation of the entire wastewater treatment system must be stopped, resulting in the inability to treat aquaculture wastewater in a timely manner, which will affect aquaculture efficiency.

[0005] Secondly, in the chemical purification stage, traditional devices use a rather crude method for adding and mixing purification agents, directly injecting the agents into the purification tank. This can easily lead to uneven distribution of the agents within the tank, resulting in excessively high local concentrations that waste the agents and may even have a secondary impact on the subsequent reclaimed water. At the same time, there is also the problem of insufficient mixing between the agents and the effluent, resulting in low efficiency of pollutant degradation reaction and affecting the final effluent purification effect. Utility Model Content

[0006] This utility model relates to an aquaculture wastewater purification and reuse treatment device, which solves the problems of traditional devices that mostly adopt a single filtration channel design, making it impossible to replace the purification medium without stopping the machine, and the problem that workers can directly inject the agent into the purification tank, which easily leads to uneven distribution of the agent in the tank and insufficient mixing of the agent with the wastewater.

[0007] This utility model provides a device for purifying and reusing aquaculture wastewater, specifically including: a purification tank;

[0008] The lower end face of the purification tank is equipped with three support legs, and a water outlet pipe is fixedly installed at the lower position of the outer end face of the purification tank. A monitoring mechanism is installed on the surface of the water outlet pipe. A connecting pipe is fixedly installed at the upper position of the outer end face of the purification tank.

[0009] The water inlet pipe has a T-shaped structure, and two outlets are provided on the lower end face of the water inlet pipe. Flanges are installed on the surfaces of the two outlets at the lower end of the water inlet pipe.

[0010] The filter tube has a flange installed on its upper and lower end surfaces, and the upper and lower ends of the filter tube are divided into frustum-shaped structures.

[0011] A drive motor is fixedly installed at the middle position of the lower end face of the purification tank. A drive shaft is connected to the upper end face of the drive motor. A mixing tooth is installed on the outer end face of the drive shaft. The mixing tooth is located in the inner bottom part of the purification tank.

[0012] The placement plate is a long strip structure with uniform through holes on its surface, and a storage tube is inserted into the inside of the through holes.

[0013] Furthermore, the monitoring mechanism includes: an electrically controlled valve installed on the surface of the outlet pipe; a controller fixedly installed on the surface of the outlet pipe, and electrically connected to the electrically controlled valve; and a probe fixedly installed on the surface of the controller, with the end of the probe located inside the purification tank.

[0014] Furthermore, the storage tube has a funnel-shaped structure, with the lower end of the storage tube being engaged in a through hole on the surface of the placement plate, and the outer end face of the storage tube fitting against the inner end face of the through hole.

[0015] Furthermore, the upper part of the connecting pipe has two water inlets, and each of the two water inlets at the upper end of the connecting pipe has a connecting flange. The upper end of the filter pipe is connected to the water outlet of the water inlet pipe through the flange, and the lower end of the filter pipe is connected to the water inlet of the connecting pipe through the flange.

[0016] Furthermore, a control valve is installed on the surface of each water inlet pipe, and the control valve is located on the outlet side of the water inlet pipe.

[0017] Furthermore, the filter tube is equipped with three filter screens, and the interior of the filter tube is filled with quartz sand.

[0018] This utility model provides a device for purifying and reusing aquaculture wastewater, which has the following beneficial effects:

[0019] 1. The dual-outlet design of the inlet pipe enables tailwater diversion. The filter pipe is equipped with three filter screens and is also filled with quartz sand. When the diverted tailwater enters the filter pipe, the quartz sand acts as the primary filter medium, adsorbing large-diameter impurities such as suspended particles, uneaten food, and feces in the tailwater, thus initially reducing the turbidity of the tailwater. The three-layer filter screen further refines the filtration of the tailwater, intercepting smaller-diameter impurities, colloidal substances, and some microorganisms in sequence.

[0020] 2. The filter tube is equipped with two sets of filters, which allows the control valve on the left side of the inlet pipe to be closed and the bolts on the flange surface to be removed when maintaining the left filter tube. At this time, the tailwater can enter the right filter tube through the drain port on the right side of the inlet pipe, thus realizing the replacement and maintenance of the filter tube without interrupting the water supply.

[0021] 3. The storage pipe is inserted into the through hole on the surface of the placement plate. The chemical agent inside the storage pipe will be evenly sprinkled into the purification tank, avoiding waste of the agent or excessive local concentration. The rotating mixing tooth can play a stirring role, so that the effluent and the purification agent are fully mixed, accelerating the reaction process of the agent with pollutants such as ammonia nitrogen, nitrite, and phosphate in the effluent, improving the degradation efficiency of pollutants, and achieving deep purification of effluent.

[0022] 4. The probe extends into the purification tank, directly contacting the effluent to collect real-time water quality parameters such as ammonia nitrogen concentration, pH value, and dissolved oxygen. The data is then transmitted to the connected controller. The controller analyzes and judges the collected water quality data. If the effluent meets the standards, the controller sends a command to the electrically controlled valve to open it. The qualified effluent is then discharged through the outlet pipe and can be directly reused in aquaculture, realizing the recycling of water resources. Attached Figure Description

[0035] Example 1: Please refer to Figures 1 to 6 :

[0036] This utility model proposes a device for purifying and reusing aquaculture wastewater, including: a purification tank 1;

[0037] Three support legs 101 are installed on the lower end face of the purification tank 1. A water outlet pipe 102 is fixedly installed at the lower position of the outer end face of the purification tank 1. A monitoring mechanism is installed on the surface of the water outlet pipe 102. A connecting pipe 103 is fixedly installed at the upper position of the outer end face of the purification tank 1.

[0038] Water inlet pipe 2 has a T-shaped structure. The lower end of water inlet pipe 2 has two outlets, and flanges are installed on the surfaces of the two outlets at the lower end of water inlet pipe 2.

[0039] The filter tube 3 has a flange installed on its upper and lower end surfaces respectively. The upper and lower ends of the filter tube 3 are divided into frustum-shaped structures.

[0040] The drive motor 4 is fixedly installed at the middle position of the lower end face of the purification tank 1. The upper end face of the drive motor 4 is connected to the drive shaft 401. The outer end face of the drive shaft 401 is equipped with a mixing tooth 4011, which is located at the bottom part of the inner side of the purification tank 1.

[0041] The placement plate 5 is a long strip structure. The surface of the placement plate 5 is evenly provided with through holes 501, and the storage tube 6 is snapped into the inside of the through holes 501.

[0042] The monitoring system includes: an electrically controlled valve 7, installed on the surface of the outlet pipe 102; a controller 8, fixedly installed on the surface of the outlet pipe 102, electrically connected to the electrically controlled valve 7; and a detection rod 801, fixedly installed on the surface of the controller 8, with its end located inside the purification tank 1. During use, the end of the detection rod 801 extends into the purification tank 1, directly contacting the effluent to collect real-time water quality parameters such as ammonia nitrogen concentration, pH value, and dissolved oxygen, and transmits the data to the connected controller 8.

[0043] The controller 8 analyzes and judges the collected water quality data. If the effluent water quality meets the standards, the controller 8 will send a command to the electrically controlled valve 7 to open the valve. The qualified effluent will be discharged through the outlet pipe 102 and can be directly reused in the aquaculture process to realize the recycling of water resources.

[0044] The storage tube 6 has a funnel-shaped structure. The lower end of the storage tube 6 is engaged in the through hole 501 on the surface of the placement plate 5. The outer end face of the storage tube 6 is in contact with the inner end face of the through hole 501. During use, the inside of the storage tube 6 is filled with chemical agents. When the placement plate 5 rotates with the drive shaft 401, the agents inside the storage tube 6 can be evenly sprinkled into the purification tank 1.

[0045] The upper part of the connecting pipe 103 has two water inlets, and each of the two water inlets at the upper end of the connecting pipe 103 has a connecting flange. The upper end of the filter pipe 3 is connected to the water outlet of the water inlet pipe 2 through the flange, and the lower end of the filter pipe 3 is connected to the water inlet of the connecting pipe 103 through the flange, which facilitates the replacement of the filter pipe 3 by the workers.

[0046] Each of the water inlet pipes 2 has a control valve installed on its surface. The control valve is located on the outlet side of the water inlet pipe 2. When replacing the filter pipe 3, the control valve on the corresponding side can be closed to ensure that the filter pipe 3 can be replaced without interrupting the water supply.

[0047] The filter tube 3 is equipped with three filter screens 301. The filter tube 3 is filled with quartz sand. In use, the quartz sand serves as the primary filter medium, which can adsorb large-diameter impurities such as suspended particles, uneaten food, and feces in the effluent, thus initially reducing the turbidity of the effluent. The three-layer filter screens 301 further refine the effluent, intercepting smaller-diameter impurities, colloidal substances, and some microorganisms in sequence.

[0048] The working principle of this embodiment:

[0049] In this invention, the inlet pipe 2, filter pipe 3, and connecting pipe 103 are connected and fixed by flanges. The wastewater generated during aquaculture first enters the T-shaped inlet pipe 2. The dual-outlet design of the inlet pipe 2 allows for wastewater diversion. The filter pipe 3 contains three filter screens 301 and is also filled with quartz sand. When the diverted wastewater enters the filter pipe 3, the quartz sand acts as a primary filter medium, adsorbing suspended particles, uneaten feed, feces, and other large-diameter impurities, initially reducing the turbidity of the wastewater. The three-layer filter screens 301 further refine the filtration, intercepting smaller-diameter impurities and colloids in sequence. After filtration, the wastewater, containing certain microorganisms, flows through the connecting pipe 103 below the filter pipe 3 and into the purification tank 1. The quartz sand inside the filter pipe 3 needs replacement and maintenance after a period of use. The filter pipe 3 has two sets of valves, allowing maintenance of the left filter pipe 3 to be performed by closing the control valve on the left side of the inlet pipe 2 and removing the bolts from the flange. The wastewater can then enter the right filter pipe 3 through the drain port on the right side of the inlet pipe 2, enabling replacement and maintenance of the filter pipe 3 without interrupting the water supply. At this point, the drive motor 4 is started, which rotates the drive shaft 401. During rotation, the mixing teeth 4011 and the placement plate 5 rotate, while the storage pipe 6 is engaged in the through hole 501 on the surface of the placement plate 5. The chemical agent inside the storage pipe 6 is evenly distributed inside the purification tank 1, avoiding waste or excessively high local concentrations. The rotating mixing teeth 4011 act as a stirrer, ensuring thorough mixing of the effluent and the purification agent. This accelerates the reaction process between the agent and pollutants such as ammonia nitrogen, nitrite, and phosphate in the effluent, improving the degradation efficiency of pollutants and achieving deep purification of the effluent. The three support legs 101 on the lower end of the purification tank 1 provide stable support for the entire device, preventing vibrations generated during the operation of the drive motor 4 from affecting the system. To ensure device stability, the probe 801 extends into the purification tank 1, directly contacting the effluent to collect real-time water quality parameters such as ammonia nitrogen concentration, pH value, and dissolved oxygen. This data is then transmitted to the connected controller 8. The controller 8 analyzes and judges the collected water quality data. If the effluent quality meets the standards, the controller 8 sends a command to the electrically controlled valve 7 to open it. The qualified effluent is then discharged through the outlet pipe 102 and can be directly reused in aquaculture, achieving water resource recycling. If the effluent quality does not meet the standards, the controller 8 closes the electrically controlled valve 7. In this case, it is necessary to continue adding chemicals to purify the effluent until the effluent quality meets the standards.
