[0024] Figure 1 The structure schematic diagram of the land-based aquaculture pond circulating automatic drainage system provided by the present application is shown in Figure 1 The land-based aquaculture pond circulating automatic drainage system comprises an aquaculture pond, a liquid level detector is arranged on the aquaculture pond, a top water inlet mechanism, a middle drainage mechanism and a bottom sewage mechanism are arranged on the aquaculture pond, the middle drainage mechanism and the bottom sewage mechanism are connected to an aquatic plant purification pond, the aquatic plant purification pond is connected to a sedimentation pond, the sedimentation pond is connected to an adsorption pond, the adsorption pond is connected to a sterilization mechanism, the sterilization mechanism is connected to a water storage pond, and the water storage pond is connected to the top water inlet mechanism.
[0025] An aeration mechanism is connected to the aquatic plant purification pond and the water storage pond.
[0026] The liquid level detector is used to detect the water level in the aquaculture pond, the aquatic plant purification pond in the land-based aquaculture pond circulating automatic drainage system is used as the first-stage purification pond of circulating water, the sedimentation pond is used as the second-stage purification pond, the adsorption pond is used as the third-stage purification pond, and the sterilization mechanism is used as the fourth-stage purification of circulating water. The water storage pond is used for storing the treated circulating water.
[0027] The land-based aquaculture pond circulating automatic drainage system has the following drainage modes:
[0028] The first mode is that the middle drainage mechanism drains water, and the top water inlet mechanism returns water at the same time, so that water can flow in the aquaculture pond, and the water quality in the aquaculture pond meets the breeding requirements when no sewage is needed, so that the water level in the aquaculture pond is in a relatively unchanged state when the water in the aquaculture pond is replaced.
[0029] The second mode is that the bottom sewage mechanism discharges sewage, and the top water inlet mechanism returns water at the same time, so that the aquaculture pond can still discharge the required circulating water under the condition of sewage, so that the water level in the aquaculture pond is in a relatively unchanged state when the aquaculture pond discharges sewage.
[0030] The third mode is that the middle drainage mechanism and the bottom sewage drainage mechanism work simultaneously, and the water flow of the middle drainage mechanism and the backwater amount of the top water inlet mechanism are controlled. The use scenario of this mode is that a large amount of fecal sludge is accumulated in the aquaculture pond, and the aquaculture pond needs to be quickly drained.
[0031] In actual aquaculture, the first and second drainage modes are frequently used, and the third mode is avoided by timely sewage drainage.
[0032] In the first mode, the liquid level detector detects the water level in the aquaculture pond, and controls the automatic drainage amount of the middle drainage mechanism to be consistent with the automatic backwater amount of the top water inlet mechanism, so that the aquaculture pond can automatically drain and automatically backwater.
[0033] In the second mode, the liquid level detector detects the water level in the aquaculture pond, and controls the automatic sewage drainage amount of the bottom sewage drainage mechanism to be consistent with the automatic backwater amount of the top water inlet mechanism, so that the aquaculture pond can automatically drain and automatically backwater under the condition of sewage drainage.
[0034] The water quality detection mechanism is provided on the aquaculture pond and the water storage tank. The water quality detection mechanism is a prior art, and the water quality detected by the water quality detection mechanism is used to switch the first mode and the second mode according to the actual situation in the actual aquaculture process, so that the land-based aquaculture pond can be circularly drained, and the circulating water backflowing into the aquaculture pond meets the aquaculture requirements through four-stage purification.
[0035] Referring to Figure 1 , the middle drainage mechanism includes a first middle drainage pipe 1 and a second middle drainage pipe 2. The first middle drainage pipe 1 is connected to the middle position of the aquaculture pond, and the second middle drainage pipe 2 is connected to the aquatic plant purification tank. The first middle drainage pipe 1 is connected with a middle drainage valve 3.
[0036] The middle drainage valve is an electromagnetic valve.
[0037] Referring to Figure 1 , the bottom sewage drainage mechanism includes a sewage pipe 4, and the sewage pipe 4 is connected with a bottom sewage drainage valve 5. The sewage pipe 4 is connected to a fecal sludge sewage tank, and the fecal sludge sewage tank is connected with a fecal pipe 6 and a sewage discharge pipe 7. The fecal pipe 6 is connected to a fecal sludge tank, and the sewage discharge pipe 7 is connected to the aquatic plant purification tank. The sewage discharge pipe 7 is connected with a first water pump 8. The bottom sewage drainage valve 5 is an electromagnetic valve.
[0038] Wherein, at the bottom of the breeding pond, through the sewage pipe 4 and the bottom sewage valve 5, the residual feed and feces at the bottom of the breeding pond can be discharged into the fecal sludge sewage tank, and the sewage pipe 4 discharges the sewage mixed with residual feed and feces. In the fecal sludge sewage tank, through the gravity sedimentation effect, the solid suspended matter such as residual feed and feces with larger particles can be precipitated at the bottom of the fecal sludge sewage tank, and then the fecal sludge at the bottom of the fecal sludge sewage tank is discharged to the fecal sludge tank through the fecal sludge discharge pipe 6 for secondary utilization. At the same time, the first water pump 8 extracts the sewage at the upper layer of the fecal sludge sewage tank through the sewage discharge pipe 7, so that the extracted sewage enters the aquatic plant purification tank for the first stage purification.
[0039] The aquatic plant purification tank is provided with emergent plants, floating plants and microorganisms, which can purify the organic pollutants and part of the heavy metal pollutants in the sewage. The aeration mechanism can provide oxygen for the aquatic plant purification tank, and the released oxygen can be dissolved in the water body to increase the dissolved oxygen content in the water body, thereby providing oxygen support for the aerobic microorganisms, aquatic animals and the like in the water body, and promoting the natural degradation and transformation of the pollutants in the sewage.
[0040] Referring to Figure 1 , a first purified water discharge pipe 9 is connected between the sedimentation tank and the aquatic plant purification tank, a first purified water discharge valve 10 is connected on the first purified water discharge pipe 9, a discharge pipe 11 is connected at the bottom of the sedimentation tank, a mud pumping pump 12 is connected on the discharge pipe 11, and the discharge pipe 11 is connected to the aquatic plant purification tank. The first purified water discharge valve 10 is an electromagnetic valve.
[0041] After the aquatic plant purification tank completes the first purification, the first purified water is discharged to the sedimentation tank through the first purified water discharge pipe 9. In the sedimentation tank, the suspended particles in the first purified water are separated from the water under the condition of relative stillness or slow flow due to the density difference between the suspended particles and the water, and the suspended particles naturally settle to the bottom of the tank under the action of gravity. The common mud particles and larger organic debris in the first purified water will gradually sink due to their density greater than water, and the relatively clear water can be pumped out from the upper part of the sedimentation tank to achieve the purpose of second-stage purification of circulating water. The sediment at the bottom of the sedimentation tank can be pumped back to the aquatic plant purification tank by the mud pumping pump 12 for decomposition again.
[0042] The first purified water discharge valve 10 can control the water flow between the aquatic plant purification tank and the sedimentation tank, so that the discharge of circulating water is more flexible.
[0043] Referring to Figure 1The adsorption tank is connected with the second purified water discharge pipe 13 between the settling tank, the second purified water discharge pipe 13 is connected with the second purified water pump 14, the adsorption tank is divided into a plurality of adsorption areas by the partition plate structure, and each adsorption area is provided with the activated carbon adsorbent.
[0044] The second purified water pump 14 draws the second purified water in the upper part of the settling tank to the adsorption tank through the second purified water discharge pipe 13.
[0045] In the adsorption tank, the activated carbon adsorbent can physically adsorb the organic matter and odor substances in the water by virtue of the rich microporous structure, adsorb these substances in the pores on the surface, thereby reducing the concentration of the substances in the fluid, and achieving the purpose of third-stage purification of the circulating water.
[0046] The partition plate structure includes a plurality of partition plates, in this embodiment, two partition plates 15 are arranged to form three adsorption areas in the adsorption tank, and the activated carbon adsorbent is arranged on the two partition plates 15.
[0047] Referring to Figure 1 The adsorption tank is connected with the third purified water discharge pipe 16 between the sterilization mechanism, and the third purified water discharge pipe 16 is connected with the third purified water discharge valve 17. The sterilization mechanism adopts the ultraviolet sterilizer, in order to make the sterilization effect of the ultraviolet sterilizer better, the third purified water discharge valve 17 is configured to control the amount of the third purified water discharged from the adsorption tank to the ultraviolet sterilizer, so that the fourth purified water flowing out of the ultraviolet sterilizer has good sterilization effect.
[0048] Referring to Figure 1 The aeration mechanism includes the nano aeration pipe and the Roots blower, and the nano aeration pipe is arranged in the water storage tank and the aquatic plant purification tank. The aeration mechanism introduces air into the water storage tank and the aquatic plant purification tank through the nano aeration pipe by the Roots blower, so as to provide oxygen for the aquatic plants and microorganisms in the aquatic plant purification tank, and improve the decomposition and conversion efficiency of the aquatic plants and microorganisms on the pollutants. In the water storage tank, the sterilized circulating water enters the water storage tank for storage, and the nano aeration pipe is used to introduce air into the water storage tank, so that oxygen is dissolved in the circulating water in the water storage tank, and the circulating water in the water storage tank is increased in dissolved oxygen, which meets the breeding requirements.
[0049] Referring to Figure 1 The top water inlet mechanism includes the top water inlet pipe 18, both ends of the top water inlet pipe 18 are connected to the top of the breeding tank and the water storage tank respectively, the top water inlet pipe 18 is provided with the top water inlet valve 19, and the top water inlet pipe 18 is connected with the water pump. The top water inlet valve 19 is an electromagnetic valve.

The stirring members 24 are fixedly connected to the support rod 23.
[0051] The rotating rod 22 includes a horizontal rod 221 at the top, one vertical rod 222 is connected to each end of the horizontal rod 221, the support rod 23 is connected to the vertical rod 222, and the plurality of stirring members 24 are connected to the support rod 23. When the pollution is discharged, the stirring members 24 can assist in discharging the pollution. The cooperation of the second mode in assisting the pollution discharge is to use the above-mentioned stirring members 24 at intervals, that is, when the pollution is discharged for ten times in succession, the rotating motor 21 is rotated to drive the rotating rod 22, the support rod 23 and the stirring members 24 to rotate, and the stirring members 24 can stir the residual feed and feces at the bottom of the culture pond to a certain extent, so that a large amount of residual feed and feces are discharged. Even if the pollution of the culture pond is often discharged, but as the culture time goes on, the bottom of the culture pond will still accumulate residual feed and feces, and this method can assist in discharging the pollution.
