摘要：Due to its broadband structure, long-term sta- bility, extremely low water solubility, non-toxicity and low cost, TiO2 has become one of the most po- tential photocatalysts in various applications. Among the different mineral forms of TiO2, anatase is the most active semiconductor in actual wastewater treatment. The photocatalytic degrada-tion process using Ti02 provides many advantages, including no sludge formation and complete conver- sion of pollutants into relatively harmless end prod- ucts. The increasing use of dyes in many industries has led to an increase in the amount of dye wastewater treated. Improper handling of dye pollu- tants in the textile industry has caused serious envi- ronmental and public health problems. It is estimated that about 15% of the dye will be lost during the dye- ing and finishing process, and then released as. wastewater. With the massive development of oxida-tive degradation, various advanced oxidation tech- nologies have become the key technologies to de- stroy stubborn compounds. In this study, the photo- catalytic activity of the TiO2/Fe-ZSM5 composite material will be chosen as the photocatalyst, and the optimal operating parameters will be determined. This experiment has the best degradation efficiency when the pH is 9, the Rhodamine B is 5 ppm, the light intensity is 538 w/m', and the TiO2/Fe-ZSM5 dosage is 0.5 g/L.
