摘要
脱硫废水污泥重金属是燃煤电厂处理脱硫废水污泥所面临的最大障碍。本文以电厂脱硫废水污泥为原料,研究了氨基二琥珀酸(IDS)新型生物可降解螯合剂在不同pH、萃取剂用量、时间条件下对脱硫废水污泥重金属的萃取影响,以期为电厂脱硫废水污泥的绿色、无害、资源化利用提供技术支撑。
Desulfurization Wastewater Sludge Heavy metal is the biggest obstacle that coal-fired power plants are facing in the treatment of desulfurization wastewater sludge. In this paper, the desulfurization wastewater sludge from power plant was used as raw material to study the effect of the novel biodegradable chelating agent of aminodisuccinic acid(IDS) on the extraction of heavy metals in the sludge of desulfurization wastewater under different pH, extractant dosage and time, Waste water sludge green, harmless, resource-based utilization of technical support.
