TECHNICAL FIELD

[0001] The present application relates to the technical field of wastewater treatment, in particular to an antibiotic wastewater photo-reaction treatment equipment and method. BACKGROUND

[0002] Antibiotic wastewater refers to the wastewater containing high concentration of antibiotics generated during the production of antibiotics. The treatment of this kind of wastewater is an important environmental challenge because the widespread use of antibiotics has led to the problem of antibiotic pollution in water bodies. The characteristics of antibiotic wastewater include high concentration of organic matter, many toxic and harmful substances, and high salt content, which makes it difficult for traditional wastewater treatment methods to effectively treat antibiotic wastewater.

[0003] Antibiotic photolysis is a method of using photocatalytic technology to treat antibiotic wastewater. The main principle of this technology is to generate strong oxidants such as hydroxyl radicals or superoxide radicals through photocatalysts under light conditions, which can break the chemical bonds in antibiotic molecules and achieve the degradation of antibiotics.

[0004] The existing wastewater photolysis equipment has the following problems: relying on solar energy as the light source, the photolysis of wastewater is more dependent on the weather, and the photolysis efficiency decreases linearly in bad weather. The use of artificial light sources for photolysis consumes a lot of energy, and the lampshade in the water body is easily contaminated, affecting the light transmittance and leading to a decrease in photolysis efficiency. Therefore, a multi-way collaborative photo-reaction treatment equipment is needed to degrade antibiotics in antibiotic wastewater to achieve the purpose of energy saving and efficiency improvement.
