SYSTEM AND METHOD FOR DEODORIZING GAS

摘要

PURPOSE: A deodorization system and a method are provided to reduce the management cost by reusing the deodorization liquid and prevent environmental pollution due to the discharge of deodorization liquid. CONSTITUTION: The deodorization method comprises the following steps. A step of collecting gas with an odor; a step of primary washing the gas with an odor by using the first deodorization liquid; a step of secondary washing the first washed gas by using the second deodorization liquid. The first and the second deodorization liquid used in the first washing and the second washing are recirculated to be reused in the first washing and the second washing. A step of purifying by injecting ozone into the first and the second deodorization liquid that was used in the first washing and the second washing is also included.
