Efficiency optimization of organic pollutant removal in pharmaceutical wastewater by microwave-assisted Fenton-like technology

摘要

Ferric sulfate or cupric nitrate was utilized as catalyst, hydrogen peroxide was utilized as oxidant, with the assistant of microwave (MW), the efficiency of Fenton-like process was improved, which included increasing TOC removal and apparent reaction rate of TOC removal, reducing the catalyst dose and oxidant dose, shortening the reaction time. Under MW radiation, the technology not only utilized dissolving ferric iron, but also used ferric flocculation, which could be seen by eyes.
