Advanced oxidation treatment experimental platform for wastewater

Abstract

The experimental platform for advanced oxidation treatment of wastewater disclosed in the present invention comprises a reaction water tank, a stirring device, a constant temperature water tank and a support; The nozzles of the water pipe, drug inlet pipe and air inlet pipe are all located at the lower part of the reaction tank, and the nozzles of the outlet pipe and the waste water return pipe are all located at the upper part of the reaction tank. Sampling ports are opened at different heights on the reaction tank. The ultraviolet lamp tube is inserted into the reaction water tank, the top of the reaction water tank is provided with a cover plate, and the cover plate has an exhaust hole; the nozzle of the sampling return pipe is located on the cover plate of the reaction water tank or the upper part of the reaction water tank; It is composed of a lifting water pump, and the two are connected through a pipeline; the water storage tank is connected with the waste water return nozzle through a pipeline. The device has the advantages of various experimental contents, convenient operation, small size, easy movement, and wide application range.

Description

Technical field [0001] The invention belongs to wastewater treatment experimental equipment. Specifically, it relates to an experimental platform, especially an experimental platform for advanced oxidation treatment of wastewater. Background technique [0002] With the development of modern industrial production, especially the chemical industry, the composition of industrial wastewater is becoming more and more complex, especially organic compounds synthesized in chemical industry, which are often difficult to remove by traditional wastewater treatment methods (mainly biological treatment methods). Therefore, countries around the world have strengthened advanced oxidation technologies. Development and application. Advanced Oxidation Process (AOPs), also known as deep oxidation technology, was first proposed by Glaze in 1987. It generally refers to chemical oxidation technology involving a large number of hydroxyl radicals in the reaction process. It is based on the use of cataly...

Problems solved by technology

This kind of pre-designed experiment is often verification, and the students' active participation is poor, so they lack interest

In addition, because different experiments use different equipment, and the equipment is often large, poor in mobility, and the number of sets is limited or even only one set, it is difficult for students to rotate in a short period of time, so the synchronization with the course is not good, which affects students' understanding of the course
