Abstract

PURPOSE: To keep concentration of an activated carbon suspension constant in order to enhance a deodorizing effect in the 3-step cleaning method for a reductive malodorous gas, by separating activatee carbon from the bottom solution of the first scrubbing tower, returning it to the first scrubbing step, and using the residual solution for scrubbing the third scrubbing step.
CONSTITUTION: In treating a reductive malodorous gas by the 3-step process consisting of the first scrubbing step for treating it with an alkaline activated carbon suspension, the second scrubbing step using an oxidant, and the third scrubbing step using an alkaline solution, part of the bottom solution 100 of the first scrubbing tower 3 is sent to sedimentation tank 18 having an inclined bottom to separate the activated carbon by settling. The separated activated carbon 19 is returned from the inclined bottom to the tower bottom, and mixed with the solution flowing down from packing 4 and a uniform suspension is again formed. Supernatant 20 separated from the activated carbon and containing a reductive substance, such as thiosulfate ions is transferred to third tower 39 to reuse it as a scrubbing solution. Filtration separation may be used using porous plates, in addition to sedimentation separation for separating the activated carbon in the first tower 3.
