Antibiotic wastewater deep degradation device based on hydrodynamic cavitation

Abstract

The invention provides an antibiotic wastewater deep degradation device based on hydrodynamic cavitation. The device comprises a stator and rotors, the stator is a hollow sealed cylinder, and rotatingshafts are installed at the two ends of the interior of the stator; a plurality of rotors are mounted on each rotating shaft and are of wheel disc structures; the two rotating shafts rotate oppositely in opposite directions; blind holes are distributed in the end surface of the rotors and the inner wall of the stator; cavitation grooves are formed in the circumferential direction of the rotors; amicro gap formed by the blind holes, the cavitation grooves, the rotor wall surface and the stator wall surface forms a current limiting structure so that a current limiting effect is achieved, and the cavitation phenomenon is enhanced; one end of the stator is provided with a feeding pipe, and the other end is provided with a discharging pipe. The two rotors rotate at a relatively high speed sothat cavitation holes in the rotors move relative to the antibiotic wastewater, and the cavitation phenomenon is caused. The method adopts hydrodynamic cavitation to degrade organic matters in the antibiotic wastewater, has the advantages of high efficiency, good magnification, large treatment capacity, continuous operation, low cost and no secondary pollution, and has wide application prospects in the field of wastewater degradation.

Description

technical field [0001] The invention relates to a deep degradation device for antibiotic wastewater based on hydraulic cavitation, and belongs to the technical field of antibiotic wastewater treatment. Background technique [0002] Antibiotics are a class of chemicals produced by the metabolism of microorganisms that kill other microorganisms. Due to the inhibitory and killing effect of antibiotics on pathogenic bacteria and pathogenic microorganisms. The wastewater discharged from the pharmaceutical process contains a large amount of antibiotics, which is not only seriously polluted but also has a high content of organic matter, which has long been a difficult point in wastewater treatment. Antibiotic residues pose a potential threat to the environment, and their indiscriminate use can also cause contamination of groundwater, surface water, sediment and soil. The effective treatment of antibiotic wastewater will also become an important research direction of wastewater tr...
