Device for promoting photosynthesis of photosynthetic bacteria in artificial culture pool

Abstract

The invention discloses a device for promoting photosynthesis of photosynthetic bacteria in an artificial culture pool. The method comprises the following steps: putting at least one photosynthetic bacterium into a black mud layer of partial regions on the bottom of the artificial culture pool, conducting light energy into the black mud layer of partial regions with the photosynthetic bacteria by using an optical conducting device, and providing light energy for the photosynthetic bacteria, thereby promoting the photosynthesis and reproduction of the photosynthetic bacteria. The optical conducting part of the device is provided with an optical conductor and a light ray scattering head device, wherein the light ray scattering head device is arranged at the bottom end of the optical conductor; an air layer structure is arranged around the optical conductor and coated on the optical conductor, so that the optical conductor is isolated from the surrounding water body; and the air layer structure has air interstice into which dry air is filled, thereby forming an air layer coating on the optical conductor.

Description

technical field [0001] The invention relates to aquaculture technology, in particular to a method and a device for improving water quality in artificial culture ponds by using photosynthetic bacteria. Background technique [0002] Aquaculture is an important production enterprise. The technology of using photosynthetic bacteria to improve water quality and improve the efficiency of aquaculture has gradually received attention in recent years. [0003] Bacteria that can use light energy as an energy source are collectively referred to as Photosynthetic bacteria (PSB for short). Photosynthetic bacteria are widely distributed in rivers, lakes, oceans and other water environments, and are also distributed in some mud and soil that can use sunlight for photosynthesis Among them, especially in the ponds polluted by organic matter, the amount is relatively large. In nature, fresh water and sea water usually contain 103-104 photosynthetic bacteria per milliliter. [0004] Accordin...

Problems solved by technology

[0016] However, aquaculture is generally carried out on a large scale in order to have economic benefits. Therefore, the cost price and ease of use of aquaculture facilities are also the key to technical feasibility and overall economic benefits.

[0017] The current devices for enhancing light to promote photosynthesis are still too complicated, for example: US Patent No. US 5716442 "Light pipe with solar bulb energy conversion system", which uses a complex light guide mechanism to introduce sunlight and artificial light into the bioreactor , and U.S. Patent No. US 6603069B1 "Adaptive, full-spectrum solar energy system", using optical fiber to introduce sunlight into the bioreactor, the cost price of the facility itself is too high, and its economic benefits cannot meet the needs of aquaculture
