Abstract
PURPOSE: To simply remove the offensive odor of hydrogen sulfide, etc., by using the fine pieces of iron oxide to which sodium hydroxide is adhered to a filter me- dium to be attached to a stack for deodorization.
CONSTITUTION: Offensive odor gas inside a night soil tank is sucked up by a fan 2b and then passed through an adsorbent 8 inside a container 5 attached detachably to the inside of a stack 1. During the passage of the gas, hydrogen sulfide present in the gas is reacted with sodium hydroxide adhered to the surface of the adsorbent to form sodium sulfide which is in turn reacted with the iron oxide in the adsorbent base material and changed into stabilized iron sulfide. The waste gas deprived of hydrogen sulfide is released from the upper part of the stack 1 to the outside.
