[0002] Thermal power plants rely on water as a medium for transferring energy and as a cooling medium for heat exchange during operation. Water plays an important role in thermal power plants. In the process of thermal power plants, water mainly has two circulation systems: one is the water vapor circulation system in the power equipment; the other is the cooling water circulation system. Therefore, power plants are not only large users of water and drainage, but also large polluters. Although the content of pollutants in the wastewater of thermal power plants is not large, due to the large amount of drainage, the total amount of pollutants discharged also increases accordingly, which will cause varying degrees of environmental pollution.

[0003] With the increasing water resource shortage and environmental protection requirements in my country, the water resource and environmental problems faced by power plants will become increasingly prominent. In order to reduce costs, reduce environmental pollution, optimize the wastewater treatment process and technology of power plants, realize wastewater resource utilization, achieve wastewater reuse until zero discharge, explore new treatment models, and improve social and economic benefits.

[0033] In this embodiment: heterogeneous catalytic oxidation treatment has been widely used in water treatment processes as a new and effective water treatment technology. Compared with the traditional oxidation treatment method in which a single material is used as a separate oxidant, the hydroxyl radical (-OH) formed under the action of the catalyst in the heterogeneous catalytic oxidation treatment has a higher reaction rate with organic matter and a stronger oxidizing property, and can oxidize almost all organic matter. The catalyst can catalyze ozone to directly oxidize organic matter in water into CO2 and H2O, or oxidize and decompose large molecular organic matter into small molecules, making it easier to degrade. The heterogeneous catalytic oxidation treatment mainly utilizes the catalytic effect of metal oxides loaded on aluminosilicate carriers, and utilizes composite metal oxides to enhance the catalytic properties, effectively improving the utilization efficiency of hydroxyl radicals. It has the remarkable characteristics of high efficiency, high strength, and long life, and is an ideal catalytic method for the new generation of oxidation.
