Process of continuously preparing n-pentanal

Treatment method of organic waste water

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.

Catalyst for treating organic wastewater and preparation method thereof

The invention discloses a catalyst for treating organic wastewater and a preparation method thereof. The catalyst is a metal carbonyl loaded catalyst, a precursor of the catalyst is one or a combination of ruthenium carbonyl and cobalt carbonyl, a second component Ce or Fe is added at the same time, and a carrier of the catalyst is selected from one or a compound oxide of active carbon, gamma-Al2O3 and TiO2. The catalyst can be used for oxidizing and degrading different organic matters with various concentrations in water under a milder condition so as to greatly reduce COD (Chemical Oxygen Demand) in wastewater and improve the removal efficiency of the COD in the wastewater.
