Abstract

The invention relates to a photocatalytic reactor and a method for wastewater treatment by the photocatalytic reactor, in particular to a batch type photocatalytic energy collection reactor and a method for wastewater treatment by the batch type photocatalytic energy collection reactor and aims to solve the problem of low photocatalytic organism degradation efficiency of existing photocatalytic wastewater treatment methods. The reactor comprises a shell, an anode chamber, a cathode chamber, a proton exchange membrane, a photoanode, guartz glass, a stirring device, a counter electrode, a capacitor and a converter. The proton exchange membrane is arranged in the middle of the shell, the shell is provided with the photoanode at one end of the anode chamber and provided with the counter electrode at one end of the cathode chamber, and the photoanode and the counter electrode are connected through an external circuit. The method includes: feeding wastewater into the reactor through a water inlet of the anode chamber, starting the stirring device, subjecting the photoanode to ultraviolet irradiation, and discharging the treated water through a water inlet hole of the anode chamber. The batch type photocatalytic energy collection reactor and the method for wastewater treatment by the batch type photocatalytic energy collection reactor are applied to the field of wastewater treatment, improve efficiency in separation of photogenerated holes and electrons and effectively and synchronously improve system production capacity and efficiency in degradation and mineralization of refractory organics in wastewater.

Description

technical field [0001] The invention relates to a photocatalytic reactor and a method for treating waste water by using it. Background technique [0002] The continuous deepening of the industrialization process has caused a huge waste of resources and energy, water pollution, energy crisis and other issues have become prominent. The development of effective wastewater treatment processes has always been the focus of environmental protection. However, traditional sewage treatment processes such as chemical, physical, and biological processes still have problems such as high energy consumption, high cost, and complex processes. More importantly, the existing sewage treatment process is purely for the purpose of removal, but the rich chemical energy contained in the sewage is ignored, and the process only for the purpose of removal has also caused a huge waste of energy. It is of great significance to develop a clean, efficient and sustainable wastewater recycling technology...
