Abstract

The invention relates to an optical bio-reactor for organic wastewater treatment, which is a device for treating organic wastewater by using photosynthetic bacteria, and can solve the problems that the growth conditions of photosynthetic bacteria are poorer, the treatment cost is higher and the efficiency for solar energy utilization is lower in the traditional photosynthetic bacterium wastewater treatment technology. The optical bio-reactor comprises a main fluidized bed reactor body and a light source arranged at the outer side of the reactor. The light shines directly through a front transparent wall and directly radiates a biofilm in a filler, and the remaining light shines through a reaction region and reflects back into the reaction region through a reflective wall and a reflective baffle. The fluidization of the biological filler in the reactor plays a wall scraping role in the inner wall of the reactor, so that the formation of the optical biofilm on the inner wall of the reactor is prevented, the light is favorably transferred to the inside of the reactor, and the light shadow problem is solved. With the structure, the higher efficiency for solar energy utilization can be obtained, the energy consumption is reduced, and meanwhile, the structure of treatment process is simple, and the operation is convenient.

Description

technical field [0001] The invention relates to a waste water treatment device, in particular to a device for treating organic waste water by using photosynthetic bacteria. Background technique [0002] The use of photosynthetic bacteria to purify high-concentration organic wastewater is a new development in wastewater biological treatment. It has the advantages of high organic matter load, small footprint, less investment and waste, low power consumption, good nitrogen removal effect and strong salt tolerance, and the bacteria produced may be used as important raw materials for comprehensive utilization, so the more are getting more and more attention. Photosynthetic bacteria refers to a general term for a large group of bacteria that perform photosynthesis without oxygen release under anaerobic conditions. At present, the photosynthetic bacteria used for organic wastewater purification are mainly Rhodopseudomonas in the family Rhodospiraceae, and have been used in High e...
