REMOVAL OF HYDROGEN SULFIDE

摘要

The flue gas is fed to a biological reactor, in which microorganisms are suspended or are present on a fixed bed. By simultaneously feeding oxygen in a quantity which is greater than the quantity of oxygen required for oxidising the hydrogen sulphide present in the flue gas to elemental sulphur, elemental sulphur or a sulphur-oxygen compound readily soluble in water is formed as the result of the metabolic process of the microorganisms. This product can readily be discharged from the reactor by means of a liquid.
