In this paper, the photochemical catalytic wastewater degradation property based on photovoltaic technology is studied. The spectral segmentation and utilization technology is taken as the bond to achieve the effective combination of photocatalytic oxidation technology and photovoltaic power generation technology to achieve the goal of sewage purification using solar energy. The photocatalytic and electrical performance of different simulated pollutants, such as methylene blue and p-chlorophenol at different initial concentrations are investigated through the established SOLWAT system. The results show that: with the SOLWAT system, the catalytic degradation rate of the simulated pollutant machine dye methylene blue exceeds 99% and the degradation rate of p-chlorophenol exceeds 90%; and the total organic carbon content of simulated wastewater is reduced by more than 80%, which proves the SOLWAT system can completely mineralize the simulated pollutants into CO2 and H2O; the degradation of colorless simulated pollutants does not affect the electrical performance of the system; the degradation of colored pollutants will increase the output power of the system.
