Abstract

The invention discloses the application of solid acid that is FexVyOz used as a Fenton-like reaction catalyst. The FexVyOz is FeVO4, Fe2V4O13 or Fe4V6O21. The catalyst can coordinate with water to form tetrabasic acid in water solution due to the strong polarization force of ferrum and vanadium, and the ferrum and the vanadium can also catalyze H2O2 to generate highly active hydroxyl radicals to effectively degrade organic pollutants. The application introduces ferric vanadate class solid acid to the Fenton-like reaction, good H2O2 activation effect is achieved, the self decomposition problem of the H2O2 is improved, and a bran-new effective way for performing the advanced treatment on biologic hard-degradation organic wastewater is provided.

Description

Application of Solid Acid FexVyOz as Catalyst for Fenton-like Reaction technical field The invention relates to the application of a heterogeneous Fenton-like catalyst. Background technique In the treatment technology of refractory organic wastewater, Fenton catalytic oxidation method can degrade and mineralize most organic substances, including highly toxic and biochemically refractory organic pollutants, under mild conditions. Compared with other advanced oxidation technologies (AOPs), it has the advantages of fast reaction speed, simple equipment and easy operation, etc. It has attracted extensive attention from environmental workers, and there have been nearly 10,000 related research reports so far. However, the traditional homogeneous Fenton oxidation method has two problems that are difficult to solve: one is that the reaction system requires a lower pH value (generally about 2 to 3), and there is a problem of catalyst loss, so in many cases, Fenton oxidation It is...
