摘要
In a method of drying a moist bulk material, such as sewage sludge, and treating the malodorous moisture-laden gas resulting from the drying process, the moisture-laden gas is introduced into waste water contained in a waste water clarifying basin of a waste water treatment plant. A system for carrying out the method includes a drying apparatus and at least one waste water basin of a waste water treatment plant, connected so that the moisture-laden gas emitted from the drying apparatus can be introduced, for example through an aerator, into the waste water. Thereby, the gas is cooled, demoisturized and deodorized, and moisture and volatile components are condensed and/or dissolved out of the gas into the waste water. The waste water is beneficially oxygenated, heated, and enriched with organic substances.
