Abstract

The invention discloses application and a method of degrading organic wastewater with a Ce-OMS-2 catalyst, and relates to the field of catalyzing and water treatment. The Ce-OMS-2 catalyst conducts degradation on the organic wastewater by activating persulfate. The method comprises the steps of adding persulfate and the Ce-OMS-2 catalyst to a wastewater solution, performing stirring and blending evenly and standing, converting nonbiodegradable organic pollutant into micromolecule pollution free matter, and achieving the purpose of degrading the organic wastewater. According to the application and the method of degrading the organic wastewater with the Ce-OMS-2 catalyst, the Ce-OMS-2 catalyst can steadily and efficiently catalyzes and activates persulfate to degrade the organic wastewater at ambient temperature and pressure, is wide in pH application rage, fast in degrading rate and low in reaction device requirement, can be applied repeatedly for many times, and has a large application prospect in the field of nonbiodegradable organic wastewater treatment.

Description

technical field

[0001] The invention belongs to the field of organic wastewater treatment, and in particular relates to a method for degrading organic wastewater by activating persulfate with a Ce-OMS-2 catalyst. Background technique

[0002] The advanced oxidation method is highly praised for its high efficiency in degrading organic pollutants. By generating free radicals, organic pollutants can be directly mineralized into small molecular organic compounds, or the biodegradability of the original organic pollutant system can be improved after treatment. To achieve the purpose of further effective degradation. The current research and application of advanced oxidation technologies are based on hydroxyl radicals (OH) and sulfate radicals (SO 4 - ·) advanced oxidation technology. where SO 4 - ·The production mainly comes from the breaking of the peroxy bond of persulfate (including persulfate and peroxodisulfate, etc.). According to different activation methods, persulf...
