[0002] Aquaculture wastewater contains a large amount of high ammonia nitrogen. The ammonia nitrogen in the wastewater not only pollutes the environment but also restricts the sustainable development of the aquaculture industry.
[0003] In traditional aquaculture, aquaculture wastewater is usually simply treated by physical, chemical or biological methods and then discharged. However, these methods often have defects such as unstable treatment effects and high operating costs. The feeding of bait mostly relies on compound feed input from the outside, which not only increases the aquaculture cost but also may have a certain impact on water quality. Content of the Utility Model
[0004] The purpose of the utility model is to propose a purification device for fish pond aquaculture wastewater in view of the problems in the background art that the compound feed input from the outside increases the aquaculture cost and affects the water quality.
[0005] The technical solution of the utility model: A purification device for fish pond aquaculture wastewater includes a culture pond for raising fish. The head and tail ends of the culture pond are respectively communicated with a water inlet pipe and a water outlet pipe, and ammonia nitrogen wastewater flows inside the culture pond;
[0006] A flow guiding member, the flow guiding member includes a baffle, a flow guiding exchange plate and a water discharge. A baffle is fixedly installed inside the culture pond at the water surface of the ammonia nitrogen wastewater, a flow guiding exchange plate is fixedly installed inside the culture pond below the baffle, and a water discharge is rotatably connected inside the culture pond at the extension line of the flow guiding exchange plate;
[0007] Microalgae and plankton are arranged at the water surface inside the culture pond.
[0008] Optionally, the flow guiding exchange plate is inclined, multiple flow guiding exchange plates are provided, and they are linearly and equidistantly distributed inside the culture pond.
[0009] Optionally, the number of baffles is the same as the number of flow guiding exchange plates. The water surface of the ammonia nitrogen wastewater inside the culture pond is higher than the ground height of the baffle, and adjacent two baffles intercept the microalgae on the water surface of the ammonia nitrogen wastewater.
[0010] Optionally, a hollow protective cover covering the water discharge is fixedly installed inside the culture pond, and the height of the hollow protective cover is lower than the water surface height of the ammonia nitrogen wastewater.
[0011] Optionally, a flow guiding heightening plate is fixedly installed inside the culture pond at a position close to the water inlet pipe, and a shielding net is fixedly installed at the top of the flow guiding heightening plate.
[0012] Optionally, a water velocity control member is provided on the side of the aquaculture pond. The water velocity control member includes an ammonia nitrogen detector and a detection probe. The ammonia nitrogen detector is fixedly installed on the side of the aquaculture pond. The ammonia nitrogen detector is electrically connected to the detection probe. The detection probe is fixedly installed between the two baffles near the tail end of the aquaculture pond.
[0013] Optionally, a water pump is fixedly installed on the water inlet pipe. The ammonia nitrogen detector is electrically connected to the water pump through a controller.
[0014] Optionally, the water inlet pipe is fixedly installed at the end of the aquaculture pond and near the bottom, and the water outlet pipe is fixedly installed at the other end of the aquaculture pond and at a position lower than the water surface of the ammonia nitrogen wastewater.

[0016] In the present utility model, microalgae absorb ammonia nitrogen in the ammonia nitrogen wastewater. The microalgae and plankton reproduce in the ammonia nitrogen environment, purifying the ammonia nitrogen wastewater. Moreover, the microalgae and plankton serve as live bait for fish, achieving self-sufficiency in green bait, reducing costs, and purifying water quality.
[0017] Furthermore, the ammonia nitrogen wastewater is diverted by the diversion exchange plate, causing the ammonia nitrogen wastewater located in the lower layer to flow to the upper layer so that the microalgae can absorb the ammonia nitrogen in the ammonia nitrogen wastewater. The ammonia nitrogen wastewater diverted by the diversion exchange plate impacts the water discharge, causing the water discharge to rotate, further mixing the ammonia nitrogen wastewater in the upper and lower layers, and increasing the absorption ratio of ammonia nitrogen in the ammonia nitrogen wastewater.
[0018] Furthermore, the detection probe is fixedly installed between the two baffles near the tail end of the aquaculture pond. Therefore, the ammonia nitrogen wastewater here is at a certain distance from the tail end of the aquaculture pond, and this distance is the remaining space, preventing the wastewater still containing a large amount of ammonia nitrogen from being discharged from the water outlet pipe.
[0019] Furthermore, the ammonia nitrogen content in the ammonia nitrogen wastewater between the two baffles near the tail end of the aquaculture pond is detected by the ammonia nitrogen detector. When the ammonia nitrogen content detected by the detection probe is high, the flow rate of the ammonia nitrogen wastewater inside the aquaculture pond is reduced, enabling the microalgae to completely absorb the ammonia nitrogen in the ammonia nitrogen wastewater; when the ammonia nitrogen content detected by the detection probe is low, the flow rate of the ammonia nitrogen wastewater inside the aquaculture pond is increased, thereby improving the purification efficiency.

[0030] Example 1
[0031] This example presents a purification device for fishpond aquaculture wastewater. As Figure 1 shown, it includes a culture pond 1 for fish farming. Microalgae and plankton are set at the water surface inside the culture pond 1. An inlet pipe 2 and an outlet pipe 4 are respectively connected to the head and tail ends of the culture pond 1. Ammonia-nitrogen wastewater flows inside the culture pond 1. The inlet pipe 2 is fixedly installed at the end of the culture pond 1 and near the bottom position, and the outlet pipe 4 is fixedly installed at the other end of the culture pond 1 and at a position lower than the water surface of the ammonia-nitrogen wastewater, so as to prevent the microalgae at the water surface from being discharged through the outlet pipe 4.
[0032] As Figure 2 and Figure 3 shown, a flow guide member 5 is arranged inside the culture pond 1. The flow guide member 5 includes a baffle 51, a flow guide exchange plate 54, and a water drain 55. The baffle 51 is fixedly installed at the water surface of the ammonia-nitrogen wastewater inside the culture pond 1. The water surface of the ammonia-nitrogen wastewater inside the culture pond 1 is higher than the ground height of the baffle 51. Two adjacent baffles 51 intercept the microalgae on the water surface of the ammonia-nitrogen wastewater to prevent the microalgae from being discharged through the outlet pipe 4.
[0033] The flow guide exchange plate 54 is fixedly installed below the baffle 51 inside the culture pond 1. The flow guide exchange plate 54 is inclined. A plurality of flow guide exchange plates 54 are provided and are linearly and equidistantly distributed inside the culture pond 1. The number of baffles 51 is the same as the number of flow guide exchange plates 54.
[0034] The ammonia-nitrogen wastewater is guided by the flow guide exchange plate 54. Since the microalgae float on the water surface of the ammonia-nitrogen wastewater, its absorption effect on the ammonia nitrogen in the wastewater at the bottom of the ammonia-nitrogen wastewater is poor. Therefore, the ammonia-nitrogen wastewater is guided by the flow guide exchange plate 54 to make the ammonia-nitrogen wastewater at the bottom flow to the water surface, so that the microalgae can completely absorb the ammonia nitrogen in the ammonia-nitrogen wastewater.
[0035] As Figure 2 and Figure 4 shown, a water drain 55 is rotatably connected at the extension line of the flow guide exchange plate 54 inside the culture pond 1. The ammonia-nitrogen wastewater guided by the flow guide exchange plate 54 impacts the water drain 55, causing the water drain 55 to rotate, further mixing the upper and lower layers of ammonia-nitrogen wastewater and increasing the absorption ratio of ammonia nitrogen in the ammonia-nitrogen wastewater.
[0036] A hollow protective cover 56 covering the water drain 55 is fixedly installed inside the culture pond 1. The height of the hollow protective cover 56 is lower than the water surface height of the ammonia-nitrogen wastewater. The hollow protective cover 56 isolates the fish and the water drain 55 to prevent the fish cultured inside the culture pond 1 from swimming to the water drain 55 and causing the fish to be hit by the water drain 55.
[0037] Inside the aquaculture pond 1 and near the water inlet pipe 2, a flow guiding and height increasing plate 52 is fixedly installed, and a shielding net 53 is fixedly installed on the top of the flow guiding and height increasing plate 52. The water entering from the water inlet pipe 2 is intercepted by the flow guiding and height increasing plate 52, and the ammonia nitrogen wastewater flows over the top of the flow guiding and height increasing plate 52, that is, towards the microalgae, and the shielding net 53 blocks the fish.
[0038] In this embodiment, the ammonia nitrogen wastewater is diverted by the flow guiding and exchanging plate 54, so that the ammonia nitrogen wastewater located in the lower layer flows to the upper layer, so that the microalgae can absorb the ammonia nitrogen in the ammonia nitrogen wastewater. The ammonia nitrogen wastewater diverted by the flow guiding and exchanging plate 54 impacts the water discharge 55, causing the water discharge 55 to rotate, further mixing the ammonia nitrogen wastewater in the upper and lower layers, and increasing the absorption ratio of ammonia nitrogen in the ammonia nitrogen wastewater.
[0039] Embodiment 2
[0040] Based on Embodiment 1, this embodiment proposes an aquaculture wastewater purification device for fish ponds, as Figure 1 shown. A water speed control member 6 is provided on the side of the aquaculture pond 1. The water speed control member 6 includes an ammonia nitrogen detector 61 and a detection probe 62. The ammonia nitrogen detector 61 is fixedly installed on the side of the aquaculture pond 1, and the ammonia nitrogen detector 61 is electrically connected to the detection probe 62. The detection probe 62 is fixedly installed between two baffles 51 near the tail end of the aquaculture pond 1. The ammonia nitrogen detector 61 detects the ammonia nitrogen content in the ammonia nitrogen wastewater inside the aquaculture pond 1 through the detection probe 62.
[0041] Since the detection probe 62 is fixedly installed between two baffles 51 near the tail end of the aquaculture pond 1, the ammonia nitrogen wastewater here has a certain distance from the tail end of the aquaculture pond 1, and this distance is the remaining space, avoiding the wastewater still having a large amount of ammonia nitrogen from being discharged from the water outlet pipe 4.
[0042] A water pump 3 is fixedly installed on the water inlet pipe 2. The ammonia nitrogen detector 61 is electrically connected to the water pump 3 through a controller. When the ammonia nitrogen content detected by the detection probe 62 is high, at this time, the ammonia nitrogen detector 61 reduces the pumping speed of the water pump 3 through the controller, thereby reducing the flow rate of the ammonia nitrogen wastewater inside the aquaculture pond 1, so that the microalgae can completely absorb the ammonia nitrogen in the ammonia nitrogen wastewater; when the ammonia nitrogen content detected by the detection probe 62 is low, at this time, the ammonia nitrogen detector 61 increases the pumping speed of the water pump 3 through the controller, thereby increasing the flow rate of the ammonia nitrogen wastewater inside the aquaculture pond 1, and thus improving the purification efficiency.
[0043] In this embodiment, the ammonia nitrogen content in the ammonia nitrogen wastewater between two baffles 51 near the tail end of the aquaculture pond 1 is detected by the ammonia nitrogen detector 61. When the ammonia nitrogen content detected by the detection probe 62 is high, the flow rate of the ammonia nitrogen wastewater inside the aquaculture pond 1 is reduced, so that the microalgae can completely absorb the ammonia nitrogen in the ammonia nitrogen wastewater; when the ammonia nitrogen content detected by the detection probe 62 is low, the flow rate of the ammonia nitrogen wastewater inside the aquaculture pond 1 is increased, thereby improving the purification efficiency.
[0044] The above specific embodiments are merely several alternative embodiments of the present utility model. Based on the technical solution of the present utility model and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
