Integrated antibiotic wastewater degradation device based on hydraulic power and ultrasonic cavitation

Abstract

The invention discloses an integrated antibiotic wastewater degradation device based on hydraulic power and ultrasonic cavitation. The device comprises a stator, a rotor, a wireless ultrasonic transducer, an ultrasonic probe and a rotating shaft, wherein the stator and the rotor are sealed cylinders, the two ends of the stator are respectively provided with a waste water inlet and a water outlet,the inner wall of the stator is provided with an ultrasonic probe, the rotor is arranged in the stator, a rotating shaft is arranged in the stator and penetrates through the stator and the rotor, therotor is fixedly connected to the rotating shaft, and cavitation blind holes are distributed in the outer side wall of the rotor; according to the method, the antibiotic wastewater is degraded by adopting a method of combining hydrodynamic cavitation and ultrasonic cavitation, the efficiency and quality are far higher than those of single hydrodynamic cavitation or ultrasonic cavitation, and the method has high efficiency and large water treatment capacity and can be used for continuous operation; the device is not influenced by the external environment, has high flexibility and can be startedand stopped at any time as required; the device is simple in structure, high in adaptability, convenient to operate, safe, reliable and convenient to maintain.

Description

technical field [0001] The invention relates to a device for degrading antibiotic wastewater, in particular to a device for degrading antibiotic wastewater by using hydraulic cavitation and ultrasonic cavitation, and belongs to the technical field of antibiotic wastewater treatment. Background technique [0002] The wastewater produced in the antibiotic production process mainly has the characteristics of complex composition, high COD value, and high concentration of toxic and harmful substances, which is the focus and difficulty in the process of pharmaceutical wastewater treatment. Traditional treatment techniques mainly include physical and chemical methods and biological methods. The physical and chemical methods used for the treatment of antibiotic wastewater mainly include: coagulation-sedimentation method, membrane separation method, photolysis method and electrolysis method. It has been paid attention to because it can recycle useful substances in wastewater while t...

Problems solved by technology

Its rotor adopts a conical structure, which has a big defect. The outer linear speed of the conical rotor is different, which also causes the utilization rate of the conical rotor to be low. At the same time, it rotates in different diameters The inertia is different, it is easy to cause equipment vibration, resulting in unstable operation of the equipment

[0007] Although the above-mentioned CN204240625U, RU 2310798C1, etc. proposed rotary cavitators, they all belonged to simple cavitation generating devices, did not explain the degradation function of antibiotic wastewater, and did not couple other physical and chemical strengthening methods, and the treatment effect needs to be improved
