Abstract

The invention discloses an organic pollution decomposing method in the water disposal domain, which comprises the following steps: aerating ozone and disposed water in the reactor with ultrasonic energy exchange device and honeycomb ceramic catalyst; setting the adding quantity per liter water at 0.4-200mg; setting the remaining time of water and ozone at 0.5-120min in the reactor; flowing out of reactor.

Description

technical field [0001] The invention relates to a method for degrading organic pollutants in the field of water treatment. Background technique [0002] With the continuous development of the economies of various countries and the continuous improvement of people's living standards, more and more attention has been paid to the hygiene and safety of drinking water, and the requirements for drinking water quality have also been continuously improved. Many countries have very strict standards that specifically require strict monitoring of substances that have a toxic impact on ecosystems. There are many kinds of pollutants that enter the water body, and the pollution of organic matter is the most common and the most harmful. For decades, domestic and foreign water treatment workers have done a lot of research work on the removal of organic matter, and they are constantly improving. [0003] The oxidation-reduction potential of ozone in the standard state is 2.07V, which can i...
