The water outlet end of the power pump 10 is fixedly installed with a water outlet pipe 12 penetrating through the breeding pond 1 and in communication with the annular pipe 5.
[0022] The number of the connecting pipes 6 is multiple, the multiple connecting pipes 6 are uniformly distributed on the inner side surface of the annular pipe 5, the connecting pipe 6 is attached to the lower surface of the inner cavity of the breeding tank 1, the number of the first flushing pipe 7 and the second flushing pipe 8 on the surface of the connecting pipe 6 is two, the two first flushing pipes 7 and the second flushing pipes 8 are symmetrically distributed on the surface of the connecting pipe 6, the length of the first flushing pipe 7 is greater than the length of the second flushing pipe 8, and the first flushing pipe 7 and the second flushing pipe 8 are annularly distributed on the bottom of the breeding tank 1.
[0023] The residue collection assembly is arranged between the breeding tank 1 and the sedimentation tank 2, and the residue collection assembly comprises a circulating pump 13 fixedly installed on the bottom of the breeding tank 1 and a drain outlet 14, one end of the drain outlet 14 is in communication with the water inlet of the circulating pump 13, the top of the drain outlet 14 is in communication with the breeding tank 1 and is located at the lowest position of the bottom of the inner cavity of the breeding tank 1, the water outlet of the circulating pump 13 is fixedly installed with a drain pipe 15 in communication with the sedimentation tank 2, the inside of the sedimentation tank 2 is fixedly installed with an overflow pipe 16 and a partition plate 17, the surface of the overflow pipe 16 is sleeved with a connecting barrel 18, and the surface of the connecting barrel 18 is fixedly installed with a grid collection frame 19.
[0024] It should be noted that the top of the overflow pipe 16 is fixedly installed with a sponge filter ring 20, the grid collection frame 19 is matched with the sedimentation tank 2, and the overflow pipe 16 penetrates through the partition plate 17.
[0025] The surface of the sedimentation tank 2 is fixedly installed with a water pump 21, the water inlet end of the water pump 21 is fixedly installed with a first water suction pipe 22 penetrating into the inside of the sedimentation tank 2 and in communication with the overflow pipe 16, the water outlet end of the water pump 21 is fixedly installed with a second water suction pipe 23 in communication with the microfilter 3, the microfilter 3 is in communication with the protein separator 4, the top of the protein separator 4 is fixedly installed with a backwater pipe 24, and the water outlet of the backwater pipe 24 is located directly above the breeding tank 1.
[0026] It should be noted that the working principle of the microfilter 3 in the embodiment is mainly to filter the breeding water by using a microporous membrane. When the breeding water to be treated enters the microfilter 3, the breeding water will pass through the microporous membrane under the action of the pressure difference, and the impurities in the breeding water will be intercepted on the membrane. In order to maintain the normal operation of the microfilter 3, it is usually necessary to clean or replace the filter membrane regularly.
[0027] The microfilter 3 mainly comprises the following structures:
[0028] The drum is generally horizontally placed in a cylindrical shape and is composed of a metal frame, and the outside is wrapped with a support net and a working net woven by stainless steel wires.
[0029] The driving device is composed of a motor and gears, and the motor drives the drum to rotate through the gears.
[0030] Water inlet system: including water inlet pipeline and overflow weir water distributor, etc. The water inlet pipeline introduces the aquaculture wastewater to be filtered into the microfilter. After the wastewater enters the overflow weir water distributor, it is stably flowed for a short time and can be evenly distributed on the filter screen of the counter-rotating filter cartridge, so that the filtering effect is better.
[0031] Water outlet system: mainly the water outlet pipeline. The clean water filtered by the filter screen is discharged from the microfilter through the water outlet pipeline and enters the next water treatment link.
[0032] Sewage discharge system: composed of a sewage collecting tank and a sewage discharge pipeline. When the filter screen is blocked to a certain extent, the water level controller senses the change in water level and starts the backwash pump. High-pressure water is sprayed onto the filter screen through the spray head, and the dirt attached to the filter screen is washed into the sewage collecting tank, thereby realizing automatic cleaning of the filter screen and ensuring the filtering effect.
[0033] Backwashing system: including a backwash pump, a backwashing pressure spray head, a liquid level sensor, a backwash pipeline, etc. When the filter screen needs to be cleaned, the backwashing system will automatically start to clean the filter screen, ensuring the normal operation of the microfilter.
[0034] Control cabinet: responsible for monitoring and controlling the operating state of the microfilter.
[0035] It should be noted that the protein separator 4 in the embodiment mainly works based on the principle of foam separation. By utilizing the characteristics that the surface of the bubbles in water can adsorb various particulate dirt mixed in the water and soluble organic matter, a large number of bubbles are generated by an oxygenation device or a vortex pump. These bubbles rise in the water and adsorb proteins, fats, sugars, etc. in the water, and form a foam layer on the water surface. The foam layer has a small density and is easy to separate from the water body, thereby removing the organic matter in the water.
[0036] The protein separator 4 mainly includes a contact chamber and a sewage collecting chamber. The water to be treated enters the upper part of the contact chamber, and the water body moves downward along the outlet. At the same time, a large number of micro-bubbles generated by the jet gas injection device enter the contact chamber, and these bubbles move upward in the contact chamber. In the moving process, the suspended and dissolved protein particles in the water body are accumulated on the surface of the micro-bubbles and pushed upward to separate from the water body, and finally enter the sewage collecting chamber at the top. In the sewage collecting chamber, as the foam slowly breaks, the organic dirt forms a sediment here, and then is discharged from the sewage outlet. The treated water flows out along the backwater pipe 24.
[0037] The working principle of the above embodiment is as follows:
[0038] The power pump 10 draws water from the culture pond 1 through the water inlet pipe 11, and then injects the water into the annular pipe 5 through the water outlet pipe 12, the water in the annular pipe 5 enters the first flushing pipe 7 and the second flushing pipe 8 through the connecting pipe 6, the water in the first flushing pipe 7 and the second flushing pipe 8 is sprayed out through the strip-shaped flushing holes 9 to form flushing to the bottom of the culture pond 1, since the bottom of the culture pond 1 is designed as an inclined surface, and the length of the first flushing pipe 7 is greater than that of the second flushing pipe 8, the flushing water flow can more effectively cover the bottom of the culture pond 1, and the food residues and feces are flushed to the lowest part of the bottom of the culture pond 1, the circulating pump 13 draws the residues and sewage at the bottom of the culture pond 1 into the drain pipe 15 through the drain port 14, and then discharges into the sedimentation tank 2, when the water level in the sedimentation tank 2 rises to a certain height, the water flows out through the overflow pipe 16, and the residues are deposited in the grid collection frame 19, the sponge filter ring 20 at the top of the overflow pipe 16 can further filter and intercept small residue particles, the water pump 21 sends the water in the overflow pipe 16 into the microfilter 3 through the first water suction pipe 22 and the second water suction pipe 23, the microfilter 3 can remove suspended solids and larger organic particles in the water, the water treated by the microfilter 3 enters the protein separator 4 for deep purification, the protein separator 4 can remove protein and other pollutants in the water, and the purified water flows back to the culture pond 1 through the backwater pipe 24.
