Background
With the rapid development of the urbanization process, a large amount of domestic and production wastewater containing refractory organic pollutants of high-concentration medicines and personal care products is discharged into a conventional sewage plant through a municipal pipe network, and then is discharged into a water environment after being treated by the sewage plant. However, the conventional sewage treatment process has difficulty in efficiently removing organic pollutants of pharmaceutical and personal care products in sewage, which in turn leads to the gradual increase of the types and concentrations of the residual refractory organic pollutants in the water environment (lake water, river, reservoir water). The residual pollutants in the water environment mainly comprise various antibiotics, environmental estrogens, pesticides and other residual compounds, the half-life period of the pollutants in the water environment is long, the biodegradation is slow, and the pollutants have potential hazards of acute carcinogenesis, teratogenesis and mutagenesis at a certain concentration.
The traditional advanced oxidation technology such as potassium permanganate method, fenton method, light Fenton method and the like has high energy consumption and is easy to generate a large amount of secondary pollution. Aiming at removing pollutants of refractory organic matters, a large number of advanced oxidation systems based on the trimetal core MOFs derived catalytic materials are applied to sewage treatment.
In recent years, MOFs-derived materials based on Bi, fe, and Mn elements have been widely used for water treatment. However, no device and practice for applying ternary metal core MOFs materials based on Bi elements, fe elements and Mn elements to micro-polluted water treatment appear yet.
