Carbon nanometer pipe catalytic ozonization water treatment method

Abstract

A process for treating water by catalytic ozonizing method includes such steps as pre-treating the water to be treated, catalytic ozonizing by using the carbon nanotubes as catalyst instead of activated carbon, and post-treating. It can oxidize the organic pollutants to become CO2 and H2O.

Description

technical field [0001] The invention relates to a water treatment method. Background technique [0002] At present, more than 90% of my country's drinking water sources are polluted, and typical pollutants are organic pollutants such as pesticides, algae toxins, and organic solvents, and conventional water treatment processes are difficult to effectively remove these organic pollutants. Ozone oxidation technology has been used in the field of water treatment for a long time, and it is widely used in special industries that require high water purity. However, the ozone oxidation technology still has the problem of strong ozone oxidation selectivity, which makes it difficult to effectively remove persistent and refractory organic pollutants in water; most of the oxidation products are organic acids. At present, the catalytic ozonation water treatment process using activated carbon as a catalyst is mostly used to replace the ozone oxidation technology. Although activated carbo...
