Problems solved by technology

[0004] At present, the removal of antibiotics in water, especially drinking water, at home and abroad mainly relies on conventional aerobic, anaerobic or anaerobic plus aerobic biological treatment methods, but due to the resistance of antibiotics, biological treatment methods cannot be fully utilized. Effect, after treatment, it cannot fully meet the drinking water standard

Abstract

The invention relates to an antibiotic wastewater degradation process. The antibiotic wastewater degradation process comprises the steps of firstly adding persulfate into pretreatment wastewater so as to obtain a mixed solution, regulating pH of the mixed solution with an acid liquid or an alkali liquid, carrying out first illumination on the mixed solution by virtue of 200nm-300nm ultraviolet light after the pH regulation, adding a thiosulfate solution into the mixed solution, and carrying out secondary illumination by virtue of 300nm-400nm ultraviolet light, so as to obtain water in which antibiotics are removed. According to the antibiotic wastewater degradation process, the antibiotics in the wastewater are degraded, the degradation speed is high, the degradation efficiency is high, the degradation effect is good, furthermore, the raw material cost is low, by-products are toxic-free, and the concentration of the antibiotics in water can be effectively controlled. Data show that the degradation rate of the degradation process to the antibiotics in the wastewater reaches up to 91%-96%.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to an antibiotic wastewater degradation process. Background technique [0002] Antibiotics in the water environment have attracted more and more attention. Their main sources are the incomplete treatment of medical wastewater and the discharge or release of residual antibiotics in biological sludge to surface water, thereby polluting environmental water bodies. In addition, manure runoff is also Major source of antibiotics present in water bodies. In recent years, residual antibiotics in the water environment have been detected in sewage and surface water in China, Europe, and the United States. The concentration reaches nanograms per liter to micrograms per liter, and the concentration will increase hundreds of times after enrichment in water. . [0003] Even at low concentrations, antibiotics in water will have an impact on the ecological environment and huma...
