Problems solved by technology

However, the adsorption microalgae biofilm photobioreactor at the present stage is facing bottleneck problems such as large area and low microalgae biomass production per unit area. Able to receive sufficient light, the microalgae biofilm adsorption carriers in the adsorption microalgae biofilm photobioreactor are mostly arranged in a horizontal single layer
Although the multi-layer arrangement of solid biofilm adsorption carriers can increase the production of microalgae biofilm per unit area, the problem of the microalgae biofilm below the top biofilm adsorption carrier is difficult to solve, which limits the development of this technology.

Abstract

The invention provides a multilayer stacked adsorption type microalgae biological membrane photobioreactor based on a light guide carrier. The multilayer stacked adsorption type microalgae biologicalmembrane photobioreactor is mainly composed of a plurality of layers of stacked solid light guide plates, wherein an LED (light emitting diode) lamp strip is mounted at the left side of each layer ofthe solid light guide plate; light reflection membranes with high light reflectivity are stuck on the other surfaces except the left side end face and the lower surface; and a liquid culture medium source layer, a micro-pore filtering membrane and a microalgae biological membrane, which are made of a porous material, are flatly paved on the upper surface of each solid light guide plate in sequencefrom bottom to top. The plurality of layers of the stacked solid light guide plates are arranged on a reactor bracket; the adjacent light guide plates are separated by the bracket; and a liquid culture medium inlet is formed in the left side of the bracket and a liquid culture medium outlet is formed in the right side of the bracket. According to the multilayer stacked adsorption type microalgaebiological membrane photobioreactor, the light guide plates are used as light source transmission and conversion media and adsorption type microalgae biological membrane carriers, and microalgae cellsare cultured in a multilayer stacking manner, so that the microalgae biomass yield of a unit occupied area is improved.

Description

technical field [0001] The invention relates to a microalgae photobioreactor, in particular to an adsorption biofilm photobioreactor. Background technique [0002] Microalgae photosynthetic carbon fixation and energy utilization technology has the ability to efficiently reduce greenhouse gas CO 2 , and the dual effects of biofuel production have become the focus of domestic and foreign scholars. The photosynthetic carbon fixation growth process of microalgae is realized through photosynthesis. Specifically, driven by light energy, microalgae cells convert CO 2 Convert water and oil into organic matter such as oil, protein, sugar, etc., and store light energy in the form of chemical energy in microalgae cells. The photoautotrophic growth of microalgae is carried out in a photobioreactor. At the same time, the photobioreactor provides suitable light, temperature, CO 2 , nitrogen source, phosphorus source and other environmental conditions. Therefore, an efficient photobior...
