廃棄物処分場で使用する硫化水素発生抑制材料の評価

抄録

The performance of materials developed to control the generation of hydrogen sulfide at waste disposal sites was evaluated. A small landfill test tank was filled with crushed waste plasterboard and the hydrogen sulfide concentration of the gas phase above the tank and the leachate discharged from the tank was measured, as well as ORP, TOC, and pH of the leachate. The results showed that the amount of hydrogen sulfide released into the gas phase and into the soaking water was reduced in the experiment with the efficient mixing of hydrog en sulfide inhibitor materials compared to the control experiment.
