Title:
二硫化物の元素状硫黄への生物学的変換方法
Document Type and Number:
Japanese Patent JP6522664
Kind Code:
B2
Abstract:
The invention is directed to a process for the biological conversion of bisulphide into elemental sulphur, comprising the following steps: a) converting bisulphide as dissolved in an aqueous solution to elemental sulphur in the presence of sulphide-oxidizing bacteria and under anaerobic conditions to obtain a first liquid effluent comprising elemental sulphur and used sulphide-oxidizing bacteria; b) regenerating the used sulphide-oxidizing bacteria as obtained in step (a) and as comprised in an aqueous solution in the presence of an oxidant to obtain a second liquid effluent comprising regenerated sulphide-oxidizing bacteria; c) separating elemental sulphur from either the first and/or the second liquid effluent; d) using the regenerated sulphide-oxidizing bacteria in step (a) as the sulphide-oxidizing bacteria.
