Method for using CeCu oxide catalyst for treating quinoline wastewater

Abstract

The invention belongs to the technical field of wastewater treatment, and particularly relates to a method for using a CeCu oxide catalyst for treating quinoline wastewater. The method comprises the steps of catalyst preparation, wherein a citric acid complex method is adopted for preparing the Cu-Ce-O compound catalyst; catalyst characterization and activity testing, wherein X-ray diffraction, ascanning electron microscope, an H2-temperature-programmed reduction technology and a X-ray photoelectron spectroscopy are adopted for catalyst characterization, for catalytic activity testing, catalytic oxidation reaction of the quinoline wastewater is carried out in a sealed round-bottom conical flask, and reaction temperature is controlled by a constant-temperature water bath. In the method forusing the CeCu oxide catalyst for treating the quinoline wastewater, an atomic spectrophotometer is used for measuring the precipitation amount of catalyst copper ions in a solution, an ultraviolet and visible spectrophotometer is used for measuring characteristic absorption situations before and after quinoline removal is conducted, and that is to say, the ultraviolet and visible spectrophotometer can be used for measuring a removal situation; the CeCu oxide catalyst is used for treating the quinoline wastewater, the device cost is low, and the treatment difficulty is small; compared with abiological treatment method, the method for using the CeCu oxide catalyst for treating the quinoline wastewater is short in used time and thorough in treatment.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, in particular to a method for treating quinoline wastewater by utilizing a CeCu oxide catalyst. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] With the continuous development of modern industry, more and more organic pollutants enter the water body through the discharge of industrial wastewater or other ways. A considerable part of the organic matter is difficult to be biodegraded, posing a serious threat to human beings and the environment. Nitrogen-containing heterocyclic compounds are a class of organic compounds with high toxicity and extensive pollution. Such compounds have a cyclic structure and have a relatively stable closed conjugated system. During the biodegradation process, the steric hindrance effect of the molecule will increase, the charge density will decrease, and it is difficult to access ...
