Abstract

An apparatus and a method for treating heavy-metal-containing wastewater using a sulfidizing agent are provided, comprising the steps of detecting the production of hydrogen sulfide gas from the above wastewater, and adding sulfidizing agent to the above heavy-metal-containing wastewater for sulfidizing treatment, so as to maintain the state that hydrogen sulfide gas is starting to be generated from the wastewater. A gas-discharging route of hydrogen sulfide gas produced from the wastewater is provided, and a monitor route having smaller diameter than that of the discharging route of hydrogen sulfide gas is led to the hydrogen sulfide gas monitor.
