Integrated antibiotic wastewater degradation device based on photocatalysis and oxidation

Abstract

An integrated antibiotic wastewater degradation device based on photocatalysis and oxidation comprises an oxidation chamber and a photocatalysis and oxidation chamber, the two chambers are connected through a communicating pipe, and a control valve is arranged at the communicating position; wherein the oxidation chamber is provided with a water inlet and a feeding hole, the water inlet is used forinputting antibiotic wastewater, and the feeding hole is used for adding a first oxidant; a catalyst feeding hole, a gas inlet and a water outlet are formed in the photocatalysis and oxidation chamber; an ultraviolet lamp tube is arranged in the catalyst feeding port, the catalyst feeding port is used for adding a photocatalyst containing nitrogen-doped modified TiO2 into the wastewater, the gasinlet is used for introducing a second oxidizing agent into the wastewater, the water outlet is used for discharging the treated wastewater, and the ultraviolet spotlight is used for providing photocatalysis conditions. According to the device, an oxidizing agent and photocatalysis are combined and cooperate to deeply degrade the antibiotic wastewater, 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 integrated antibiotic waste water degradation device which couples an oxidant and a photocatalytic process, and belongs to the technical field of antibiotic waste water degradation. Background technique [0002] The wastewater produced by the production of antibiotics is a kind of organic wastewater with high chroma, high concentration of refractory and biotoxic substances. It is often discharged directly or treated by traditional methods, which often fails to meet the discharge standards, which seriously harms the water environment and thus endangers human health. For dealing with the water crisis, photocatalysts have the advantages of low energy consumption, sustainable utilization and environmental friendliness. But at present, most photocatalysts are not very efficient for ultraviolet rays in solar energy. Therefore, it is of great significance to study photocatalysts with excellent solar ultraviolet utilization and bet...
