Description

Circulating water fishery system based on combined natural ecological purification

Technical Field

The invention relates to the technical field of fishery aquaculture sewage treatment, and in particular to a circulating water fishery system based on combined natural ecological purification.

Background technique

Fishery is a social industry sector in which humans utilize the material transformation function of organisms in water bodies to obtain aquatic products through fishing, breeding and processing. Fishery breeding is an important part of agricultural production and provides people with abundant aquatic products. However, with the expansion of fishery breeding scale and the improvement of breeding technology, the water pollution problem caused by fishery breeding is becoming increasingly serious. In order to solve the sewage problem in fishery breeding ponds, the existing technology is to purify the sewage in fishery breeding ponds through a circulating water fishery system. The existing circulating water fishery system usually includes fishery breeding ponds, sedimentation tanks, aeration tanks and microfiltration machines.

However, in the process of treating fishery wastewater in the existing circulating water fishery system, although aquatic plants are planted in some sedimentation tanks or fishery breeding ponds to improve the purification effect of the water in the breeding ponds, when some aquatic plants die, when replacing the aquatic plants, it is necessary to equip a hand-rowed boat to carry the staff to the vicinity of the aquatic plant planting tank, and then manually replace the dead aquatic plants, which is not only labor-intensive, but also easily causes a safety hazard of falling into the water during the process of replacing aquatic plants on the water; moreover, although the existing circulating water fishery system has a filter net structure that can filter out debris in the water through the filter net, the surface of the filter net is easily covered by these debris, affecting the filtering effect, and when cleaning, the staff needs to go into the water to clean, so it is extremely inconvenient.

Working principle of this embodiment: When the circulating water fishery system is in operation, the water flow inside the fishery breeding pond 1 is transported to the primary sedimentation tank 101 through the water pipe fittings. The suspended matter in the water is precipitated by the sedimentation effect of the primary sedimentation tank 101. Then, the water flow in the primary sedimentation tank 101 is transported to the aeration tank 102 through the water pipe fittings. The aeration treatment is carried out by the aeration tank 102. The aerated water is then transported to the secondary sedimentation tank 103 through the water pipe fittings. The suspended matter in the water is further precipitated by the secondary sedimentation tank 103. Then, the water inside the secondary sedimentation tank 103 is purified by the aquatic plants planted in the aquatic plant planting tank 501. The aquatic plants can absorb nutrients and pollutants in the water. , such as nitrogen, phosphorus, organic matter, etc., so as to purify water quality and reduce water pollution. The purified water is then transported to the inside of the hydraulic box 603 through the water pump 601, and then the water is discharged to the inside of the coarse filter box 104 through the water outlet of the hydraulic box 603. The debris in the water is filtered through the filter screen on the filter screen frame 1042 inside the coarse filter box 104. The filtered water is then transported to the microfilter 105 through the water pipe fittings, and microfiltered through the microfilter 105. The water after microfiltration is then transported to the nitrification tank 106 through the water pipe fittings, and the ammonia nitrogen in the sewage is converted into nitrate nitrogen, so as to achieve the purpose of removing ammonia nitrogen. Finally, the purified water is transported back to the inside of the fishery breeding pond 1 through the water pipe fittings to achieve circulating purification.

During the process of treating fishery sewage, when some aquatic plants die and need to be replaced, the staff only needs to control the rotation of the shaft of the lifting motor 507 to rotate the active pulley, the driven pulley and the transmission shaft 506, and then rotate the two rotating nuts 505 through the two second bevel gears. At this time, the two lifting screws 508 will move the horizontal fixed plate 502, the debris collection net box 503, and the aquatic plant planting trough 501 upward under the action of the thread. When the height of the bottom end face of the summary net box 5011 is higher than the height of the upper end face of the secondary sedimentation tank 103, the shaft of the driving motor 403 is controlled to rotate, thereby rotating the driving screw 404, and then the driving nut 407 moves the sliding frame 401 and the aquatic plant planting trough 501 forward under the action of the thread, thereby removing the aquatic plants from the water, and then the staff can replace the dead aquatic plants.

When the bottom end surface of the debris collection net box 503 moves upward to be flush with the upper end surface of the secondary sedimentation tank 103, the driving gear 706 will engage with the rack 406, and then when the debris collection net box 503 continues to move upward with the cleaning mechanism 7, the driving gear 706 will drive the outer ring of the one-way bearing 705, the inner ring of the one-way bearing 705, the supporting shaft 701, and the two sprockets 702 on the left to rotate counterclockwise, thereby driving the two chains 703 and the sweeping brushes 704 outside the two chains 703 to rotate counterclockwise, and the debris (such as aquatic plant roots) deposited on the bottom end surface of the debris collection net box 503 is cleaned into the inside of the summary net box 5011 through the counterclockwise rotating sweeping brush 704.

When the water flows through the hydraulic box 603, it will drive the rotating impeller 606, the rotating shaft 604, the first synchronous pulley 605, the second synchronous pulley 806, the transmission shaft 804 and the transmission disk 805 to rotate, and then the transmission disk 805 drives the toggle column 807 to rotate, and the toggle column 807 drives the vertical fixed plate 803 and the three anti-blocking brushes 802 to move up and down, so as to automatically remove the debris covering the surface of the filter screen to avoid affecting the filtering effect.
