Title: Treating method of drainage containing nitrate nitrogen
Inventor: MURAKI TSUTOMU
IPC: C02F1/70
Filed: 2001-10-29
Abstract: PROBLEM TO BE SOLVED: To provide a treating method of drainage containing nitrate nitrogen capable of treating the drainage containing nitrate nitrogen with a small-sized device, chemically and simply, and stably with respect to a load variation for a treater such as a change in the concentration of the nitrate nitrogen, and moreover effectively treating even nitrate nitrogen of high concentration to convert to nitrogen gas. SOLUTION: After nitrate nitrogen is reduced to nitrite nitrogen by adding hydrazine or its salt to a drainage containing nitrate nitrogen, and contacting with a sponge copper catalyst, nitrite nitrogen is reduced to nitrogen gas by contacting with a palladium catalyst in the presence of hydrazine or its salt. Nitrate nitrogen can be directly reduced to nitrogen gas by contacting with the sponge copper catalyst and the palladium catalyst at the same time. This method can be performed at normal pressure, and the pH of the liquid is preferably not less than 8.
