Abstract

The invention discloses a method of degrading and removing anti-depression psychotropic drugs in water by ionizing radiation. The method removes, by mineralization, the anti-depression drug citalopram, which contains a free radical remover and active group accelerant H2O2, through the redox action between citalopram and high-reaction-activity H OH and eaq-secondary particles generated by electronbeam bombardment of a solution; the method is a simple universal advanced oxidization method, having the advantages of high efficiency, zero initiator, no need for experimental condition control, lowenergy consumption and low cost; the method is efficient in treating wastewater containing the anti-depression psychotropic drug citalopram, with short treatment cycle, complete degradation, mild reaction conditions, zero secondary pollution and significant comprehensive economic benefit; the method is particularly applicable to efficient quick removal of trace organic pharmaceutical active compounds and other emerging pollutants; the method has a promising development and application prospect in wastewater treatment and ecological environment protection.

Description

technical field [0001] The invention relates to a method for treating wastewater containing refractory drugs, in particular to a method for treating wastewater containing antidepressant drugs, in particular to a method for treating high-energy ray irradiation degradation, which is applied in the technical fields of wastewater treatment and radiation chemical treatment. Background technique [0002] With the rapid development of social economy and the continuous acceleration of the pace of life, people's mental pressure is gradually increasing, and depression has become a high incidence in today's society. The extensive use and consumption of antidepressant psychotropic drugs has led to the gradual accumulation of such pharmaceutically active compounds in the environment, showing "pseudo-persistence", posing potential health risks to humans, terrestrial ecosystems, and aquatic ecosystems. This issue has received increasing attention from the scientific community. Many antide...
