A self -cleaning spiral optical biological reactor

Abstract

The invention discloses a self-cleaning spiral photobioreactor, which belongs to the technical field of microalgae cultivation. Including the sump, including the submerged layer and the equipment layer from bottom to top; the submerged layer is a sealed bag made of rubber material to hold the sewage to be treated; its upper end is a cone angle structure and is provided with a reflective layer; the main shaft, vertical Installed in the middle of the liquid collection tank; a spiral three-dimensional spiral culture unit is arranged on the main shaft, and the three-dimensional spiral culture unit is composed of a three-dimensional spiral transparent plate; the water distribution pipe is spirally arranged along the lower end of the inner edge of the three-dimensional spiral culture unit. There are micro-jet nozzles corresponding to the upper surface of the three-dimensional spiral culture unit; the top of the water distribution pipe is connected to the water pump located in the equipment room through the water inlet pipe arranged in the main shaft; the water pump is connected to the sealing bag through the filter device. The invention can be directly placed in polluted urban inland rivers and lakes, and can be floated on the water surface, so that the movement is convenient, the working area is large, and the cost of comprehensive treatment is low.

Description

A self-cleaning spiral photobioreactor technical field The present invention relates to microalgae cultivation technical field, particularly a kind of self-cleaning spiral photobioreactor. Background technique Microalgae are photoautotrophic organisms, widely distributed in freshwater, oceans and various soils on the earth, and have the ability to grow It has the characteristics of rapidity, high photosynthetic efficiency, strong adaptability, and asexual reproduction. Microalgae can utilize light energy, CO2, organic carbon in wastewater, ammonia Nitrogen, organic phosphorus and other substances are carbon sources, nitrogen sources and phosphorus sources, and absorb heavy metals to purify wastewater; they can also absorb gases such as CO2 in the atmosphere. The body acts as its own metabolic carbon source, and produces O2 to fix CO2 to purify the air; at the same time, microalgae contain a variety of high value-added biological actives quality, such as polyunsatura...

Problems solved by technology

[0005] At present, the research direction is mainly to explore the cultivation method of microalgae, which is mainly to blindly enhance the light intensity and couple the microalgae culture with various ratios of wastewater. There are relatively few studies on aesthetics and biological carbon fixation. Moreover, most photobioreactors occupy a large area, cannot be folded and contracted, have a low utilization rate of light, and cannot use clean energy such as wind energy and light energy as The energy supply and operation of the bioreactor, and the research on sewage treatment and air purification are rarely involved. Therefore, it is necessary to propose a foldable three-dimensional spiral photobioreactor to realize the automatic adjustment of light intensity and enhance the bioreactor. Carbon sequestration efficiency, so as to purify air and sewage while harvesting high value-added algae biomass, and can use wind energy to cultivate microalgae, reducing the cost of cultivation and purification
