System for purifying aquatic water by using photosynthetic bacteria

Abstract

The invention discloses a system for purifying aquatic water by using photosynthetic bacteria. The system comprises a base and a photoreactor main body, guide rails are vertically arranged at the two ends of the base, each guide rail comprises a pair of vertically-arranged first rails, and arched second rails are arranged at the upper ends of the pair of first rails; the base is arranged in a hollow shape, a driving shaft is horizontally arranged on one side in the base, a main curtain piece is wound on the driving shaft, a first through hole is formed in the base in a penetrating mode, and the main curtain piece penetrates through the first through hole and then is in sliding connection with the first track and the second track. Driven shafts are horizontally arranged at the two ends in the base, side curtain pieces are wound on the driven shafts, a pair of second through holes are formed in the base in a penetrating mode, and each side curtain piece penetrates through the corresponding second through hole, then is connected with the corresponding pair of first rails in a sliding mode and covers the first rails and the second rails. The corrosion of rainwater to the tubular photobioreactor is reduced, so that the service life of the tubular photobioreactor is ensured.

Description

technical field [0001] The invention relates to the technical field of aquaculture water purification devices, in particular to a system for purifying aquaculture water by using photosynthetic bacteria. Background technique [0002] Photosynthetic bacteria are a type of microorganisms that use light as energy and can use organic matter, sulfide, ammonia, etc. in nature as hydrogen donors and carbon sources for photosynthesis under anaerobic light conditions. Different from green plants, their Photosynthesis does not produce oxygen. [0003] In aquaculture, it can degrade toxic substances such as nitrite and sulfide in water, and realize functions such as serving as bait, purifying water quality, preventing diseases, and serving as feed additives. Photosynthetic bacteria have strong adaptability, can tolerate high-concentration organic wastewater, have a certain ability to tolerate and decompose poisons such as phenol and cyanide, and have strong decomposition and transforma...

AI Technical Summary

Problems solved by technology

[0006] However, when it rains, since the tubular photobioreactor is exposed outdoors for a long time, it is easy to be eroded by rainwater, which will affect the service life of the tubular photobioreactor, and needs to be improved.
