Abstract

The invention belongs to the technical field of catalysts, and discloses a supported catalyst filter fiber for catalytic degradation of pollutants in water and a preparation method and application ofthe supported catalyst filter fiber. The method comprises the following steps: 1) preparation of a catalyst: mixing potassium permanganate, potassium ferrate, soluble oxalic acid metal salt and cobaltsalt dissolved in water in water, carrying out hydrothermal reaction at 100-130 DEG C for 7-14 hours, and carrying out subsequent treatment to obtain the catalyst, and 2) uniformly mixing a catalyst,water and glue to obtain a glue solution, and coating the surface of a non-woven fabric with the glue solution, and drying to obtain the catalyst-loaded filter fiber. The method disclosed by the invention is simple, and the prepared supported catalyst filter fiber can efficiently degrade organic pollutants in water at normal temperature, so that organic matters in the water can be quickly enriched on the surface of the catalyst, and the purpose of quick catalytic degradation is achieved. The supported catalyst filter fiber is used for oxidative degradation of organic pollutants in water.

Description

technical field [0001] The invention belongs to the field of catalyst preparation, and in particular relates to a catalyst filter fiber for catalytically degrading organic matter in water at normal temperature, its preparation and application in degrading organic pollutants. Background technique [0002] Water is one of the important natural resources essential for human survival and development. At present, with the development of industrialization and the large increase of human demand, industrial production produces a large amount of water pollutants, which poses a serious threat to the water environment. [0003] Pollutants in water resources include heavy metals, pathogenic bacteria, radioactive substances and organic pollutants. Among them, organic pollutants are the most polluting to the environment and human health, and organic pollutants have the characteristics of large discharge and refractory degradation. At present, the methods for dealing with organic polluta...
