Problems solved by technology

The traditional method will bring about a problem. The imported sludge will carry a large number of pathogens, forming a dead end for epidemic prevention. It is impossible to achieve the whole process of disinfection and epidemic prevention. If a large amount of sludge is disinfected separately, the economic cost is huge, and the disinfection cannot be guaranteed. Effect

Abstract

The invention relates to a medical wastewater treatment method integrating ozone disinfection and enhanced antibiotic drug degradation, and belongs to the technical field of medical wastewater treatment. The method is carried out by adopting an integrated ozone disinfection and enhanced antibiotic drug degradation medical wastewater treatment device. The treatment device comprises an anaerobic tank, an anoxic tank, an aerobic tank and a sedimentation tank in the A2 / O process, and a magnetic nano ozone bubble water preparation system used for generating magnetic nano ozone bubble water; the method comprises the following steps: effluent in the A2 / O process is treated by a magnetic nano ozone bubble water preparation system to generate magnetic nano ozone bubble water; magnetic nano ozone bubble water is injected into return sludge in the A2 / O process, and the magnetic nano ozone bubble water carries the return sludge to enter the anaerobic tank, the anoxic tank, the aerobic tank and thesedimentation tank for circulation by utilizing the adhesion characteristics of magnetism and nano bubbles. Full-process disinfection and epidemic prevention of medical wastewater treatment can be realized, and antibiotic drug degradation and sludge in-situ recessive reduction are enhanced.

Description

technical field [0001] The invention relates to a medical wastewater treatment method, in particular to a medical wastewater treatment method that integrates ozone disinfection and enhanced degradation of antibiotics, and belongs to the technical field of medical wastewater treatment. Background technique [0002] Existing A for medical wastewater treatment 2 / O process includes anaerobic pond, anoxic pond, aerobic pond, sedimentation pond, existing A 2 When the O process is in operation, the raw sewage and the return sludge discharged from the sedimentation tank enter the anaerobic tank simultaneously for phosphorus release, and at the same time part of the organic matter undergoes ammonification, and the sewage is treated in the anaerobic tank and then enters the anoxic tank for denitrification and denitrification. , the nitrate nitrogen in the anoxic pool is sent from the aerobic pool through the internal circulation, and the mixed solution treated in the anoxic pool ent...
