3D catalyst for catalytic degradation of organic pollutants as well as preparation and application of 3D catalyst

Abstract

The invention belongs to the field of organic wastewater treatment, and particularly discloses a method for preparing a 3D catalyst for catalytic degradation of organic pollutants, which comprises thefollowing steps: reacting a raw material solution containing cotton stalk powder, acid and a catalytic metal source in an oxygen-containing atmosphere at 100-350 DEG C to obtain the 3D catalyst, wherein in the raw material solution, the concentration of the acid is 35-85%. In the reaction process, a certain amount of non-ionic cellulose mixed ether is added, the structural stability of the 3D catalyst can be further improved, the loading effect of a catalytic metal source can be further improved, and the pesticide catalytic effect is further improved.

Description

Technical field:

[0001] The invention belongs to the field of wastewater treatment, and in particular relates to a three-dimensional biocatalyst capable of catalyzing the degradation of organic pollutants in water bodies. Background technique:

[0002] As a large agricultural country, my country needs hundreds of billions of jins of grain to feed 1.4 billion people every year. Rice, as a large-scale food product grown in my country, is accompanied by the use of a large number of herbicides containing quinclorac every year, and this type of herbicide has a complex structure. , difficult to degrade, and has the characteristics of residual period. Scientific research shows that the long-term accumulation and retention of residual quinclorac acid in rice, fruits and vegetables in the human body will cause chronic poisoning, pose a potential threat to human health, and even induce many chronic diseases. It promotes canceration of cells in various tissues of the body, and long-term ...
