Embodiment 1

[0028] In summer (July), in the Shandong area, the Haematococcus pluvialis in the later stage of large-scale cultivation will be cultivated in the photobioreactor 1 in a water body of 10m 3 , into the built 15m 3 In the sedimentation tank 2. After settling for 24 hours, the supernatant in the sedimentation tank 2 was observed under a microscope. When the algae cells were not visible in the field of vision, the supernatant water in the sedimentation tank 2 was pumped into the large solar water heater device 3, and the water temperature at this time was measured. is 25°C. Under sunny conditions, after 8 hours of heating, the water temperature in the large-scale solar water heater device 3 reaches above 95° C. After maintaining for 1 hour, the water body is discharged and enters the cooling pool 4 for natural cooling. When the temperature of the water body in the cooling pool 4 is measured to be 25°C, the water body is re-entered into the photobioreactor 1 for cultivating Haema...

Embodiment 2

[0033] In winter (December), in the Shandong area, adopt the same method as in summer, and the Haematococcus pluvialis in the late stage of large-scale cultivation in photobioreactor 1 will be cultured in a water body of 10m 3 , into the built 15m 3 In the sedimentation tank 2. After settling for 24 hours, the supernatant in the sedimentation tank 2 was observed under a microscope. When the algae cells were not visible in the field of vision, the supernatant water in the sedimentation tank 2 was pumped into the large-scale solar water heater device 3, and at the same time, the The water temperature is 25°C. Under sunny conditions, after 8 hours of heating, the water temperature in the large-scale solar water heater device 3 reaches above 80°C. After maintaining for 1 hour, the water body is discharged and enters the cooling pool 4 for natural cooling. When the water temperature is measured to be 25°C, put the water body back into the photobioreactor 1 for cultivating Haemato...

Abstract

The invention provides a method for treating and reusing Haematococcus pluvialis large-scale culture wastewater. The method utilizes the heat sensitivity characteristic of the growth inhibitors in the Haematococcus pluvialis large-scale culture wastewater and adopts a technology of precipitation after heating to remove the growth inhibitors, so the recycle of the wastewater is realized. The invention simultaneously provides a method for realizing the treatment and the reuse of the Haematococcus pluvialis large-scale culture wastewater. The device which adopts a large solar apparatus to heat the wastewater has the advantages of energy saving, environmental protection, low cost, and strong maneuverability.

Description

technical field [0001] The invention relates to a method and a device for treating and reusing wastewater, in particular to a method and a device for reusing wastewater from Haematococcus pluvialis large-scale cultivation, and belongs to the field of resource reutilization. Background technique [0002] Haematococcus pluvialis (referred to as Haematococcus, Haematococcus pluvialis ) is a single-celled green algae that accumulates a large amount of astaxanthin under certain conditions in the late growth period. Astaxanthin is a derivative of β-carotene. It is a carotenoid additive with great potential. It has strong anti-oxidation and is known as super vitamin E. It has broad prospects in food, feed, cosmetics, medicine and other fields. Currently, the supply capacity of the international market is limited. , which is far from meeting the demand. Utilizing the ability of Haematococcus pluvialis to accumulate a large amount of astaxanthin under specific conditions is the mo...
