Title:
APPARATUS AND METHOD FOR MICROALGAE-MICROORGANISM SYNERGISTIC TREATMENT OF AQUACULTURE EFFLUENT
Document Type and Number:
WIPO Patent Application WO/2024/077858
Kind Code:
A1
Abstract:
The present invention relates to the technical field of aquaculture effluent treatment, in particular to an apparatus for microalgae-microorganism synergistic treatment of aquaculture effluent. The apparatus comprises an aquaculture part; the aquaculture part is in communication with an effluent discharge part; the effluent discharge part is in communication with an effluent treatment part; and the effluent treatment part is in communication with the aquaculture part. The effluent discharge part comprises an effluent discharge pipe in communication with the aquaculture part; the end of the effluent discharge pipe away from the aquaculture part is in communication with the effluent treatment part; and an effluent discharge pump is arranged on the effluent discharge pipe. The effluent treatment part comprises a second housing; the bottom end of the second housing is in communication with the effluent discharge pipe; the top end of a side wall of the second housing is in communication with the aquaculture part; the interior of the second housing is provided with a plurality of flow guide plates; and microalgae are inoculated on outer side walls of the flow guide plates. In the present invention, microalgae and original microorganisms in aquaculture effluent form microalgae-microorganism symbionts, which can reduce carbon, reduce nitrogen and remove phosphorus synchronously and have few effects on aquaculture organisms, so that the quality of discharged water can be greatly improved without the need of subsequent precipitation devices.
