Embodiment approach 1

[0033] This embodiment provides a reaction device for ultrasonically strengthening microalgae to treat wastewater and promote microalgae oil synthesis, the device includes a microalgae cultivation reactor 1, an illumination device 2, an aerator 3, an ultrasonic reactor 4 and a further Liquid pump 5, wherein: the outside of the microalgae cultivation reactor 1 is provided with an illumination device 2; the bottom of the microalgae cultivation reactor 1 is provided with an aerator 3; the water outlet of the microalgae cultivation reactor 1 is connected to The water inlet of the ultrasonic reactor 4 is connected, and the water outlet of the ultrasonic reactor 4 is connected with the water inlet of the microalgae cultivation reactor 1 through a liquid inlet pump 5 .

[0034] In a preferred manner, the lighting device 2 can be arranged behind the microalgae cultivation reactor 1 .

[0035] In a preferred manner, the water inlet and water outlet of the microalgae cultivation reactor...

Embodiment approach 2

[0040] On the basis of the first embodiment, this embodiment has added technical features: an ultrasonic transducer 7 is provided inside the ultrasonic reactor 4; the ultrasonic transducer 7 is connected to an ultrasonic generator 8 arranged outside the ultrasonic reactor 4.

[0041] Preferably, the ultrasonic conditions are an ultrasonic frequency of 18 kHz, an ultrasonic power of 20 W, and a total ultrasonic time of 10 minutes.

[0042] The technical features added in this embodiment are based on the principle that low-intensity ultrasonic waves can increase the permeability of cell membranes to promote mass transfer, and appropriate ultrasonic frequencies can increase the metabolic rate of cells and accelerate cell regeneration under the premise of ensuring the integrity of cells. The growth of microalgae has obtained the effect of increasing the oil content of microalgae and reducing the cost of microalgae cultivation.

Embodiment approach 3

[0044] On the basis of Embodiment 1, this embodiment has added technical features: the upper, middle and lower parts of the microalgae cultivation reactor 1 are respectively provided with sampling ports 12 with anaerobic rubber plugs.

[0045]The technical features added in this embodiment facilitate the collection and sealing of samples at different heights in the reaction zone, and reduce the effect of the external environment on the reaction device.

Description

technical field [0001] The invention relates to a reaction device for ultrasonically strengthening microalgae to treat waste water and promoting microalgae oil synthesis, and belongs to the technical field of microalgae water treatment devices. Background technique [0002] Water is the resource that people rely on for survival. The lack of water resources and the pollution of water bodies restrict the rapid development of my country's social economy. It is necessary to seek a green and efficient method for purifying sewage. At the same time, the development of economy and urban industrialization is inseparable from energy, and it is very necessary to find clean and renewable new energy to alleviate energy problems. Microalgae can survive in harsh environments. While removing nitrogen and phosphorus substances in sewage and adsorbing heavy metal ions, through a series of physiological and biochemical reactions, organic matter in sewage is used to synthesize biomass energy an...
