Abstract

The invention provides an antibiotic wastewater degradation device coupled with hydraulic, ultrasonic cavitation and oxidation processes. The device comprises a stator, a rotor, an ultrasonic generator and an ultrasonic transducer. The stator is a hollow sealed cylinder, and the ultrasonic transducer extending into an inner cavity of the stator is arranged on the outer wall of the stator; stator cavitation holes are distributed in the inner wall of the stator. Two wheel discs are arranged in the stator, and each wheel disc is fixedly connected to one rotating shaft; the two rotating shafts aresymmetrically installed at the two ends in the stator respectively. Wheel disc cavitation holes are distributed in the circumferential direction and the end face of each wheel disc. One end of the stator is provided with a wastewater inlet pipe and an oxidant pipe, and the other end is provided with a liquid outlet pipe. According to the device, the antibiotic wastewater is degraded by coupling hydraulic power, ultrasonic cavitation and an oxidizing agent, the cavitation energy density is enhanced, the effect of the oxidizing agent is improved, the antibiotic wastewater is degraded efficiently and synergistically, the effect is good, the amplification performance is good, the treatment capacity is large, continuous operation can be achieved, the cost is low, secondary pollution is avoided, and the device has wide application prospects in the field of wastewater degradation.

Description

technical field [0001] The invention relates to an antibiotic wastewater degradation device coupled with hydraulic, ultrasonic cavitation and oxidation processes, and belongs to the technical field of antibiotic wastewater treatment. Background technique [0002] Antibiotics are a class of drugs used to treat bacterial infections in humans and animals. Since the advent of penicillin in the 1940s, more than 100 antibiotics have been developed and used successively. They have played a huge role in the treatment of infectious diseases. However, the irrational use of antibiotics, the misunderstanding of antibiotic use, the lack of necessary drug management and scientific guidance, and the large-scale use of antibiotics in animal husbandry and aquaculture to increase production have gradually begun to show the negative effects of antibiotics on humans and the ecological environment. The stability and complexity of the structure and the characteristics of high biological toxicity ...
