污泥添加粉煤灰堆肥化对Cu、Zn、Pb形态的影响
Effect of Fly Ash to Status on Cu,Zn,Pb During Composting of Sewage Sludge
摘要
Abstract
The hazard of heavy metals in sewage sludge is one of the most important factors that influences land use;the hazard of heavy metals not only depends on the amount but also on the speciation,which could react on the migration and the bioavailability of heavy metals.The experiment studied the speciation of heavy metals(Cu,Zn and Pb) after composting of sewage sludge including sawdust as regulator and fly ash as a passive agent.The results showed that composting could make Cu more active but adding fly ash could restrain that effectively;composting could change Pb from unstable speciation to stable speciation;adding fly ash during composting could make Zn more stabilized;when the amount of fly ash was 35% of sewage sludge,composting had an apparent effect of stabilizing on heavy metals(Cu,Zn and Pb) of easy migrate speciation.关键词
