    摘要: 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.

    摘要: A catalyst composition including component A and component B, the component A being a carrier, preferably having a honeycomb structure, and being a single-component oxide or a multi-component composite oxide of at least one metal of titanium, silicon and zirconium, and the component B being a catalyst component deposited on the carrier of component A and being at least one member selected from the group of noble metals and other specifically limited metals and their oxides, is very effective for decomposing and removing poisonous organic chlorine compounds, such as dioxin and the like, or poisonous organic chlorine compound-forming substances contained in an exhaust gas exhausted from an incinerator of an incineration plant provided with the incinerator and a dust collector. In addition, and the generation of the poisonous organic chlorine compound from the incineration plant can be prevented.

    摘要: A method for the treatment of waste water, which comprises wet oxidizing said waste water with a molecular oxygen-containing gas of an amount 1.0 to 1.5 times the amount thereof theoretically necessary for decomposing at least one substance selected from the group consisting of organic substances and inorganic substances present in said waste water to nitrogen, carbon dioxide, and water at a temperature not exceeding 370.degree. C. under a pressure enough for said waste water to retain a liquid phase in the presence of a solid catalyst comprising of a first catalytic component formed of titanium dioxide, a second catalytic component formed of the oxide of an element of lanthanide series, and a third catalytic component containing at least one metal selected from the group consisting of manganese, iron, cobalt, nickel, tungsten, copper, silver, gold, platinum, palladium, rhodium, ruthenium, and iridium or a water-insoluble or sparingly water-soluble compound of said metal.
