The waste water may contain heavy metal ions, organic solvents, pathogenic microorganisms and other toxic and harmful substances, and if the waste water is not effectively treated, the direct discharge can cause serious pollution to the environment and endanger public health. Therefore, it is important to develop an efficient and reliable laboratory wastewater treatment device.
Currently, laboratory wastewater treatment techniques mainly include physical, chemical and biological methods. However, these conventional methods have problems of low treatment efficiency, high running cost, risk of secondary pollution, and the like. In recent years, the photocatalysis water treatment technology gradually becomes a research hot spot by virtue of the advantages of high efficiency in degrading organic pollutants, no secondary pollution, simplicity and convenience in operation and the like, and is considered as a wastewater treatment technology with great potential.

To avoid agglomeration and clogging of the particles, stirring devices are usually provided in the reactor. However, the introduction of stirring means increases the energy consumption and the complexity of the apparatus. In addition, the rotation of the stirring device can also cause mechanical abrasion on the particle carrier, so that titanium dioxide is fallen off, and the service life of the catalyst is shortened. And the blocking condition of the bed layer is difficult to monitor in real time, the starting and the running of the stirring device cannot be accurately controlled, and unnecessary energy consumption and carrier abrasion are caused.
