Biofiltration water treatment equipment for recirculating aquaculture system

Abstract

The invention discloses biofiltration water treatment equipment for a recirculating aquaculture system, which structurally comprises a support frame, a storage tank, a turntable, a protective cover and an access pipeline, wherein the support frame is in welded connection with two sides of the storage tank, the access pipeline is in nested connection with the left side of the storage tank, the topend of the support frame is in welded connection with the bottom of the protective cover, and the turntable is in clearance fit with the inner side of the protective cover. The turntable is in clearance fit with the inner side of the storage tank and comprises a filter plate, a clearance cavity, a reverse osmosis plate, a transmission machine and a motor, the filter plate is movably matched with the inner side of the clearance cavity, the transmission machine is movably matched with the central position of the filter plate, and the inner wall of the clearance cavity is in welded connection with the top end of the reverse osmosis plate; the motor is movably matched with the inner part of thetransmission machine, and thetransmission machine is in bolt fixing with the outer wall of thereverseosmosis plate. According to the equipment, sewage is treated in advance before entering the equipment, what is avoided is that dirt directly enters the equipment and influences the purification effect of the equipment, thedirt is effectively smashed, and the phenomenon that a honeycomb filter screen is blocked due to the fact that the green algae directly enters the equipment is avoided.

Description

technical field [0001] The invention relates to the field of biological filtering equipment, in particular to a biological filtering water treatment equipment used in a circulating aquaculture system. Background technique [0002] The biological turntable process is a kind of biological water treatment technology. This treatment method allows bacteria and fungi to grow and breed on the turntable disc to form a film-like biological activated sludge, that is, to form a biofilm. After the sewage passes through the inside of the turntable and The biofilm formed inside is in contact, so that the microorganisms on the biofilm absorb the organic pollutants in the sewage as nutrients, so that the sewage can be further filtered; [0003] However, there are the following deficiencies in the prior art: the current biological filtration water treatment equipment used in circulating aquaculture systems refers to biological turntables, and the equipment is placed near the aquaculture pond...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a biological filtration water treatment equipment for a circulating aquaculture system, to solve the current problem of a biological filtration water treatment equipment for a circulating aquaculture system in the prior art. Biological turntable, the equipment is placed near the breeding pond to filter the water source inside the breeding pond. During the use process, the turntable adopts a briquette-shaped disc, because the briquette-shaped disc has a strong bearing capacity and can disperse the external forces from all sides, so that The resistance of the honeycomb structure to the extrusion force can provide a growth environment for the biofilm to form a biofilm in a short period of time. When the culture tank contains green algae plants and sewage enter the equipment together, the green algae will be rolled into the disc with the sewage for filtration , which in turn causes green algae to block the honeycomb holes in the honeycomb disc, resulting in the problem that the filtration effect and production capacity are gradually reduced
