Recently, the "algal symbiotic biological filter for shrimp tail water treatment" researched and invented by Cui Hongwu of the Yellow Sea Fisheries Research Institute of the Chinese Academy of Fishery Sciences has been authorized by the national invention patent, patent number: ZL 2021109829655
.
.
The present invention relates to the technical field of
aquaculture equipment.
After the two ends of the active shaft are fixed through the active gears on both sides, they are screwed together with the walls of the front and rear sides of the storage tank; Fixed connection of the drive motor to the rear end of the active shaft; After the two ends of the driven shaft are fixed through the driven gears on both sides, they are screwed together with the walls of the front and rear sides of the storage tank; The rotating shafts at both ends of the coral velvet roller are inserted in the clamping seat; The front and rear sides of the baffle are fixed to the inner walls of the support plates on the front and rear sides, and the baffle is embedded on one side wall of the baffle; The resistance spring is embedded in the baffles on both sides, and the drive mechanism is set between the two support plates; The shunt pipe is connected with the outlet end of the No.
2 pumping pump, the shunt pipe is provided with a through hole, and the coral fleece roller filters and collects the microalgae in the shrimp tail water, and then forms a stable algal symbiotic biofilm system under light conditions, which can be used for nitrogen removal and phosphorus removal of shrimp tail water, and reduces COD to a certain extent
