Abstract

The invention relates to a seal type pipeline culture device of bait microalgae and a microalgae pipeline culture method. The device comprises a plurality of producing units, wherein each unit comprises an underground pipeline (14) and a plurality of vertical transparent pipelines which are connected in parallel; each transparent pipeline is communicated with the underground pipeline (14); the transparent pipeline comprises a barrel body (1), a barrel body upper end cover (21) and a barrel body flange (11); the barrel body upper end cover (21) is provided with a water inlet (9) and a feeding opening (8); and a lamp tube shell (4) is inserted into the barrel body (1), and the barrel body is provided with a cleaning valve steel pipe (3) and a cleaning valve (2). Meanwhile, the barrel body upper end cover (21) is also provided with an electromagnetic exhaust valve (20) and a through hole (21) which is communicated with an air inlet pipe (18). In the invention, processed animal excrement is used as a microalgae nutrient solution. The device has the advantages of high culture density, high stability and high risk resistant capacity and can realize the industrialized production of the bait microalgae.

Description

technical field

[0001] The invention relates to microalgae biotechnology and sewage treatment technology, in particular to a cultivation device for producing bait microalgae for harmless treatment of organic sewage by using microalgae and a pipeline cultivation method for microalgae using the device. Background technique

[0002] The ecological distribution of microalgae is extremely wide on the earth. According to research, it is close to 50% of plant species. It has diversity, complexity and particularity in terms of germplasm, genetic information, biochemical composition, and metabolic pathways, which further determine its potential. Nutritional and pharmaceutical value, from which humans may develop a large number of structurally specific high value-added bioactive ingredients. Microalgae are rich in protein, polysaccharides, unsaturated fatty acids and other nutrients, such as spirulina, which can be used in food and medicine; contain a variety of pigments, such as Porp...

Examples

Embodiment

[0055] According to the production device for cultivating microalgae provided by the present invention, the microalgae is microalgae with high lipid content such as green algae, Haematococcus, Haematococcus pluvialis, diatoms or Cyanococcus. Inoculation of algae liquid is 1 / 60 of the volume of the reactor, in which the microalgae liquid can not need each external inoculum, only need to collect 3 / 4 to 99 / 100 of the cultured microalgae liquid each time, and the rest is the following Inoculated microalgae in the subculture.

[0056] CO required in the microalgae culture of the present invention 2 The gas comes from CO emitted from power plants or farming processes 2 The gas source is treated to remove the impurity gas and particulate (including dust) substances contained in the gas that are not conducive to the reproduction of microalgae, and the CO from the power plant 2 Abundant, cheap, and hot CO 2 , available via hot CO 2 or heating CO 2 To adjust the culture temperature...
