Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, and in particular to a water purification device for shrimp farming. Background Technology

[0002] In the shrimp farming industry, with the continuous increase in stocking density and the advancement of the farming cycle, a large amount of pollutants such as shrimp excrement, uneaten feed, and microbial metabolic products accumulate in the farming water. These pollutants lead to an increase in the content of harmful substances such as ammonia nitrogen and nitrite in the water, a decrease in dissolved oxygen content, and water quality deterioration. This not only affects the growth and health of shrimp but also easily triggers diseases, resulting in a decrease in farming yield and economic losses.

[0003] Existing purification devices cannot filter solid impurities of different particle sizes in aquaculture water in a graded manner, which increases the burden on subsequent purification stages. At the same time, biological purification tanks cannot aerate evenly and do not create a good living and metabolic environment for microorganisms. Therefore, a purification device for shrimp aquaculture water is proposed to address the above problems. Utility Model Content

A first control valve 12 is installed at the connection between the inlet pipe 11 and the sedimentation filter box 1. The inlet end of the inlet pipe 11 is connected to the outlet pipe of the aquaculture pond. The sedimentation filter box 1 is equipped with a first filter screen 13 and a second filter screen 14. The first filter screen 13 is located to the left of the second filter screen 14. The right end of the sedimentation filter box 1 is connected to the left end of the biological purification box 2 through a connecting pipe. A valve is installed on the connecting pipe. The right end of the sedimentation filter box 1 is equipped with a cleaning inlet pipe 15 for cleaning. The bottom outlet of the left end of the sedimentation filter box 1 is equipped with a second control valve 16. A sewage discharge pipe 17 is installed at the outlet of the second control valve 16 and is connected to a sewage collection tank. The internal filter opening of the first filter screen 13 is larger than the internal filter opening of the second filter screen 14.

[0021] The biological purification box 2 is filled with biological packing material. An aeration mechanism is set at the bottom of the biological purification box 2. The aeration mechanism includes an aeration pipe 23 and an air pump 21. The aeration pipe 23 is evenly distributed at the bottom of the biological purification box 2. The air pump 21 is connected to the aeration pipe 23 through the adapter block 22 to deliver air into the biological purification box 2, providing sufficient oxygen for the aerobic metabolism of microorganisms.

[0022] The biological purification box 2 is connected to the adsorption box 3 through a connecting pipe. The connecting pipe is equipped with valves, which can adjust the flow rate and residence time of each water flow according to the actual treatment needs. An activated carbon purification layer 31 is provided below the water inlet of the adsorption box 3.

[0023] The front end of the adsorption box 3 is connected to the rear end of the disinfection box 4 through a connecting pipe. The top of the adsorption box 3 is equipped with a fixing frame 41. The bottom of the top plate of the fixing frame 41 is equipped with an ultraviolet sterilizer 42. An ultraviolet lamp is installed inside the ultraviolet sterilizer 42.

[0024] When using this shrimp farming water purification device, first open the first control valve 12 on the inlet pipe 11. The water in the farming pond flows into the sedimentation filter box 1 through the inlet pipe 11. Inside the sedimentation filter box 1, the water passes sequentially through the first filter screen 13 and the second filter screen 14.

The impurities are discharged with the water through the sewage pipe 17 to the sewage collection tank.

[0025] After pretreatment, open the valve on the connecting pipe between sedimentation filter tank 1 and biological purification tank 2, allowing the filtered water to flow into biological purification tank 2. Start air pump 21; air enters aeration pipe 23 via adapter block 22, aerating the biological purification tank 2 and providing sufficient oxygen for the microorganisms attached to the biological packing material. The microorganisms decompose organic matter and harmful substances in the water. Adjust the valve on the connecting pipe between biological purification tank 2 and adsorption tank 3 according to actual treatment needs to control water flow and residence time for more thorough purification.

[0026] Water flowing from biological purification tank 2 enters adsorption tank 3, where residual organic matter, pigments, and odors are adsorbed and removed by the activated carbon purification layer 31. Subsequently, the water flows through a connecting pipe into disinfection tank 4, where the ultraviolet disinfector 42 is activated. The ultraviolet light emitted by the lamps irradiates the water, killing harmful bacteria, viruses, parasites, and other microorganisms. Finally, the purified water flows back to the aquaculture pond through outlet pipe 43, completing the entire purification cycle.
