Exhaust gas treatment apparatus

An exhaust gas treatment apparatus comprising:

• a gas/liquid reactor contacting a treatment liquid and an emission-regulated gas included in exhaust gas, to absorb and remove the emission-regulated gas;
• a treatment liquid supply tank supplying the treatment liquid to the gas/liquid reactor;
• and
• a gas/liquid separation treatment liquid regeneration unit regenerating a waste treatment liquid in which the emission-regulated gas is absorbed, into a treatment liquid in which the emission-regulated gas is not absorbed, and supplying the regenerated treatment liquid to the treatment liquid supply tank,
• wherein the gas/liquid separation treatment liquid regeneration unit includes a gas/liquid separation membrane through which a gas can pass but a liquid cannot pass, wherein the gas/liquid separation membrane partitions a liquid flow path through which the waste treatment liquid flows and a gas flow path through which the emission-regulated gas flows, and
• the emission-regulated gas absorbed in the waste treatment liquid flows through the liquid flow path and passes through the gas/liquid separation membrane, and moves to the gas flow path in which a low partial pressure of the emission-regulated gas is formed, to separate the emission-regulated gas and the treatment liquid.
