Problems solved by technology

Its disadvantages are firstly that it occupies a large area, and it is not suitable to be promoted in areas where land is scarce (such as the Pearl River Delta region); secondly, this treatment method uses natural light as the light source and is subject to seasonal, regional, and diurnal restrictions.
Most of the photobioreactors developed are in the laboratory scale, and there are common problems such as low utilization rate of light energy, difficult monitoring and control of flow behavior, poor mass transfer, difficulty in control and amplification, etc.

Abstract

The present invention discloses an algae-bacteria symbiotic fluidized bed processing system for highly-concentrated organic wastewater, which is composed of a fluidized-bed device, a water inlet device, a gas inlet device, an illumination device, a monitoring device and a filtering device. Then invention combines the fluidization technology with the algae-bacteria symbiotic water treatment technology to realize the high-efficient treatment of highly concentrated organic wastewater. The invention can effectively treat the highly concentrated organic wastewater, such as food waste water, brewing wastewater and sugar-making wastewater, and is high in mass-transfer efficiency and easy to realize large-scale treatment and continuous operation. Moreover, the invention can better realize sufficient contact among wastewater, carrier and air to enhance utilization efficiency of light energy.

Description

technical field [0001] The invention relates to a wastewater treatment system, in particular to an algae-bacteria symbiotic fluidized bed treatment system for treating high-concentration organic wastewater. Background technique [0002] After the 1980s, a large number of laboratory and experimental studies have been carried out on the production of algae and the treatment of sewage at home and abroad, involving the selection of algae species, the structure of microalgae treatment reactors, and the removal of organic matter and nitrogen and phosphorus nutrients by algae-bacteria. mechanism and many other aspects. For example, Guo Siyuan of South China University of Technology in China has studied the growth of microalgae, and developed a pipeline airlift magnetic treatment photobioreactor microalgae production system and monitoring method; The cultivation of chlorella, golden algae, etc. has been studied. Li Chuan, Gu Guobang, etc. used a three-phase internal circulation fl...
