Problems solved by technology

However, the open culture process is greatly affected by the natural environment such as light and temperature, and is easily polluted by fungi, protozoa and other algae species. At the same time, water evaporation is serious and carbon dioxide supply is insufficient. These factors will lead to low algae cell culture density. Harvesting costs are higher
The algae species that can adapt to large pond cultivation must be algae species that can grow rapidly in extreme environments. However, there are not too many algae species that can meet these conditions. There are many attempts to improve the system, but they can only be used for spirulina, Cultivation of a few microalgae that can tolerate extreme environments, such as Chlorella and salina
At present, there are many types of closed photobioreactors, such as fermenter type, tube type and flat plate type, columnar airlift type, etc. The common defects of them are high energy consumption and high cost in commercial production

Embodiment 1

[0036] Reactor assembly: closed runway pool-type photobioreactor, assembled by 3 reactor units, each reactor unit is 3m long, 1.5m wide, the depth of the pool is 45cm, and a row of PE with a thickness of 5mm is installed in the middle of the pool The deflector and the reactor unit interface are fixed by bolts, and rubber gaskets are added between the interfaces to prevent seepage; the width and depth of the sealing groove around the upper opening of the pool body are 10cm, and conventional disinfectant is injected into the sealing groove when in use; Light reflection device, LED lamp, ultraviolet germicidal lamp, power pump, and cover with a sealing cover.

[0037] Reactor disinfection: continuously turn on the ultraviolet germicidal lamp for 2 hours, inject saturated ozone water from the injection hole, soak for 10 hours, and discharge the ozone disinfectant from the discharge hole.

[0038]Light culture of freshwater chlorella: Inject the culture solution to a depth of 35cm,...

Abstract

The invention relates to a closed runway pool type photobioreactor applicable to large-scale light culture of a variety of algae. The reactor adopts a water seal method for sealing, and is equipped with a low shearing force circulating device and an automatic temperature control system. The production cost and operation cost are low, and the microalgae yield is high.

Description

technical field [0001] The invention relates to a microalgae photobioreactor, which is a bioreactor product suitable for large-scale closed cultivation of seawater and freshwater microalgae, and belongs to the technical field of microbial cultivation. Background technique [0002] Microalgae play a pivotal role in carbon cycle, new energy development and human food development. in CO 2 Under the multiple pressures of emission reduction, emerging bio-energy production, and food crisis, microalgae carbon sequestration and biological development technology has attracted much attention because it can simultaneously meet the multi-directional development needs of "carbon sequestration", "production capacity" and "food". [0003] At present, the research on microalgae biological development technology in my country is mainly concentrated in the upstream, and most of the research and development on the cultivation process is basically in the laboratory stage. Under the conditions...
