The present invention provides a method of treating waste water including nitrogen-containing organic compounds to convert these compounds into harmless gases without performing a post-treatment. The method comprises spraying waste water in a heated space to gasify the waste water into waste gas, and oxidizing the waste gas by contacting it with a catalyst to convert the nitrogen-containing organic compounds into harmless gases. An apparatus for treating waste water using the method is also disclosed.

Method of treating waste water and apparatus for treating waste water using the method

A process for producing aromatic or heterocyclic nitriles, which comprises reacting an alkyl-substituted aromatic hydrocarbon or an alkyl-substituted heterocyclic compound with ammonia and oxygen in the presence of a catalyst composition comprising (a) at least one composite oxide selected from the group consisting of a binary composite oxide comprising titanium and silicon, a binary composite oxide comprising titanium and zirconium and a ternary composite oxide comprising titanium, silicon and zirconium, and (b) an oxide of at least one metal selected from the group consisting of vanadium, molybdenum, tungsten, chromium, antimony, bismuth, phosphorus, niobium, iron, nickel, cobalt, manganese and copper.
