Abstract

The invention provides a continuous efficient cell disruption treatment method based on frequency-mixed ultrasound. According to the method, a sample to be processed is pumped into an ultrasonic reaction vessel, and then frequency-mixed ultrasonic treatment is conducted in the ultrasonic reaction vessel. The ultrasonic reaction vessel is provided with three areas, a set of replaceable power ultrasonic transducers with different frequencies are arranged in each area in a face-to-face mode, power is between 500 W and 3 kW, the frequencies of one set of power ultrasonic transducers are 20 kHz and 28 kHz, the frequencies of another set of power ultrasonic transducers are 28 kHz and 35 kHz, and the frequencies of the other set of power ultrasonic transducers are 20 kHz and 35 kHz. Ultrasonic waves synthesized by two ultrasonic transducers in each set can achieve different frequencies and sound intensities. Different kinds of biological cells in different sizes can be subjected to frequency-mixed ultrasound while passing an ultrasonic treatment area, and then effective disruption treatment is achieved. The method breaks the limitation of the prior art that fixed ultrasonic frequency can only be used for treating specific biological cells and improves disruption efficiency.

Description

Technical field

[0001] The invention relates to the technical field of ultrasonic processing, in particular to a continuous high-efficiency cell wall breaking processing method based on mixed-frequency ultrasound. Background technique

[0002] With the acceleration of the process of urbanization and industrialization in my country, pollution has become a bottleneck restricting economic development. It is urgent to control environmental pollution and strengthen environmental protection. In many pollution control studies, cell wall breaking has attracted the attention of scientists. For example, the flood of algae in the water body needs to destroy the plant cell wall of the algae, so that the intracellular material can flow out to achieve the purpose of controlling algae pollution; In the process of sludge treatment, because there are a large number of biological cells in the sludge, its combined water in various forms makes the water content of the sludge very large. Therefore, t...
