Abstract

The invention discloses a testing device and a method for sterilizing a liquid by means of a high voltage electric field coupled with ultrasonic treatment. The device comprises a first slipway group,a second slipway group, a third slipway group, a fourth slipway group, a coupling agent assembly, an ultrasonic excitating assembly, a high speed camera, a supporting rack and a microfluidic module. The coupling agent assembly comprises a coupling agent supporting block, a coupling agent channel and a coupling agent control air cylinder; the ultrasonic excitating assembly comprises an ultrasonic probe supporting block, an annular probe temperature sensor and an ultrasonic probe; and the microfluidic module comprises a glass negative, a PDMS film, an insertion needle, a capillary steel tube, alower bottom plate and an upper cover plate. According to the device provided by the invention, the liquid is sterilized by means of the high voltage electric field coupled with ultrasonic waves assisted by a microfluidic technique, and a sterilizing effect on different bacteria can be achieved by adjusting parameters such as power of the electric field and power of a sound field.

Description

technical field [0001] The invention belongs to the technical means of non-thermal sterilization treatment of microfluidic chips, and in particular relates to a high-voltage electric field coupled ultrasonic treatment liquid sterilization test device and method. Background technique [0002] At present, there are many researches on high-voltage electric field sterilization and ultrasonic treatment of non-thermal sterilization types at home and abroad, and too much ultrasonic work will cause excessive local temperature rise, resulting in changes in other properties of the liquid. However, the joint sterilization of the two has not been discussed in depth. And there is no such device on the market. Microfluidic technology is a test method aimed at experimental conditions to explore the sterilization mechanism under small flow rates. The invention is based on microfluidic chip technology and proposes a high-voltage electric field coupled ultrasonic treatment liquid sterilizati...
