Modular photosynthetic bioreactor system, algae culture method and fixture set

Abstract

The invention discloses a modularized photosynthetic bioreactor system, an algal culture method, and a clamping tool group. The modularized photosynthetic bioreactor system comprises at least one reactor, an air inlet pipe, a discharging pipe, a charging pipe, and an air exhaust pipe. The reactor consists of a plurality of clamping tool groups, at least one thin film cylinder, and at least one aeration plates. The algal culture method comprises the steps: carrying out disinfecting, culturing and collecting; pouring water, air and hypochlorous acid liquid into the reactor at the disinfecting step, so as to carry out sterilization; pouring sodium thiosulfate liquid into the reactor so as to neutralize residual chlorine; pouring a culture medium and algae fluid into the reactor at the culturing step, wherein microalgae grows to a stable period; and collecting the microalgae in the reactor after the stable period at the collecting step. According to the invention, the cost is low, the modularization is achieved, and the operation is easy.

Description

technical field [0001] The invention relates to a modular photosynthetic bioreactor system and an algae cultivation method, in particular to a modular photosynthetic bioreactor system and an algae cultivation method in which the reactor is composed of a clamp ring group and a film cylinder so that the reactor has airtight characteristics method. Background technique [0002] Most of the existing microalgae culture systems are cultivated in open culture ponds. However, in order to increase the unit yield of microalgae and avoid the invasion of foreign algae-eating organisms, the development of photosynthetic bioreactors has gradually attracted attention in recent years. Generally, the body of the photosynthetic bioreactor is made of transparent materials, such as glass or polymethyl methacrylate (acrylic), polyvinyl chloride, polycarbonate and other plastic materials. Although the bioreactor made of the above materials can obtain good microalgae cultivation effect, the produ...

Problems solved by technology

[0005] Another example is a bag-type reaction gas suspension design, which can eliminate the wire frame support and facilitate assembly and operation. However, an air-lift aeration tube is installed in the center of the photosynthetic reactor. This device can only generate local disturbances inside the reactor. Unable to fully mix, in addition, there are phenomena such as uneven aeration and flow retention
