In today’s thermal power plants, due to improper operation, the condensation system often drops other substances, such as turbine oil. In this way, trace oil in the condensate will contaminate the resin, corrode the thermal equipment, cause unnecessary losses to the thermal power plant, and the amount is huge. On this basis, many scholars began to study the method of removing trace oil from condensate. In this paper, we use photocatalytic degradation to help us effectively remove trace turbine oil in condensed water. Photocatalytic degradation is a chemical reaction carried out under the action of light. The photocatalytic reaction requires the reactants to absorb light energy and excite it to an excited state, and the energy source for degrading all pollutants into inorganic substances is the photon energy. This is one of the most commonly used methods for handling trace oils. This article also uses ultrasonic technology to effectively degrade trace oils. Experiments show that the photocatalytic degradation method can effectively degrade trace oil. Titanium dioxide, the catalyst used in the photocatalytic degradation method, has the best catalytic effect when the forging environment is 500°C and it is loaded twice.
