Abstract

The invention discloses a treatment method of organic waste water. In the treatment method, a supported catalyst made of carbonyl metal is used, so that the chemical oxygen demands (COD) of various high-concentration organic waste waters can be effectively reduced under the mild condition; and the catalyst is convenient for separation and can be recycled, reaction condition is mild, and the treatment method is easy to operate.

Description

technical field [0001] The invention provides a method capable of performing catalytic wet oxidation treatment on various organic matter in waste water. Specifically, a supported catalyst prepared from a carbonyl metal complex is used as a precursor to treat organic wastewater under relatively mild conditions, and belongs to the field of water treatment technology and environmental functional materials. Background technique [0002] With the rapid development of industry, the problem of water pollution is becoming more and more serious. Especially with the development of pharmaceutical, chemical, dyestuff and other industries, there are more and more high-concentration refractory organic wastewater, which is a major difficulty in wastewater treatment. [0003] In recent years, developed countries in the world have attached great importance to the development of innovative alternative technologies in an attempt to improve processing efficiency and reduce processing costs.
