Abstract

The invention discloses an efficient composite Fenton reagent. Ferrous oxalate is used as a main catalyst; other metal salts which are one or several kinds of materials from copper metal salts, cobaltmetal salts, aluminum metal salts, manganese metal salts, nickel metal salts, cadmium metal salts, chromium metal salts, cerium metal salts and palladium metal salts, are added; The reagent has the advantages that the cost during the sewage treatment can be obviously reduced; a complicated device is not needed; the oxidization efficiency is obviously improved; meanwhile, the requirement on the use environment is reduced; good oxidization capability is realized under the acidic and basic conditions; meanwhile, the preparation method of the composite Fenton reagent is simple; the operation is convenient.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a high-efficiency composite Fenton reagent. Background technique [0002] In the process of modernization, with the continuous advancement of science and technology and industry, human civilization has made unprecedented achievements. However, in the process of social progress, our environment has also suffered a lot of damage. Wastewater is an important factor in environmental damage. Now Nowadays, people's awareness of environmental protection is getting stronger and stronger, and the country also attaches great importance to the control of environmental pollution, especially the treatment of wastewater pollution. Because wastewater contains a large amount of organic matter that is difficult to degrade, there are many difficulties in the purification and reuse of wastewater. [0003] In 1894, the French chemist Fenton discovered for the first time that organic compo...
