根据能值理论与分析方法,在绘制福州经济技术开发区生态流能量系统图、建立能值分析表的基础上计算了2006-2012年开发区生态系统各主要能值评价指标,从环境、经济、社会三个角度对开发区能值指数7年来的变化趋势进行了分析讨论.结果表明,福州经济技术开发区大量依赖系统外部投入的煤炭、钢材等不可更新资源,环境负载率基本逐年增加,废物能值比相对较低但小幅上升;系统净能值产出率均高于10并且持续攀升,能值货币比均低于国内基准8.67E+12sej/($),反映了开发区经济发展态势良好;系统能值密度约为2.40E+21sej/m2,高于国内发达地区北京;可持续发展指数较低,但随着区内电子信息行业的快速发展,可持续发展指数总体呈上升趋势,预计随着国家生态工业示范园区的进一步建设,开发区的中远期发展是可持续的.研究结果为开发区未来经济与环境协调发展的科学管理提供指导依据.

The main aim of this study was to separate heave metals and yield crude bio-oil from a heavy metals hyperaccumulator harvest,Pteris vittata,through hydrothermal upgrading process.
Zinc recovery form zinc calcine containing high content of iron by selective reduction roasting was investigated.Zinc oxide was separated from franklinite to upgrade soluble zinc during the reduction
Heavy-metal-containing neutralization sludge(NS)and zinc leaching residue(ZLR)are difficult to dispose,both of which two main solid wastes are produced in Pb/Zn smelting process.
The use of mechanical ball milling for the solidification of arsenic-containing fly ash was investigated in the present study.The leaching concentration of fly ash before and after treatment was analy
It was suggested by results of thermal calculation that the zinc ferrite should be selectively reduced into magnetite,instead of ferrous oxide(FeO),to keep the iron from being extracted.
The in situ immobilization of heavy metals using various easily obtainable amendments is a cost-effective and practical method in the remediation of contaminated sites.
Municipal solid waste incineration(MSWI)fly ash failing TCLP test,mostly Pb and/or Cd,is identified as a hazardous waste and usually treated by cement solidification and landfill.
Spent hydrodesulphurization(HDS)catalyst contains rare metals such as cobalt,nickel,molybdenum(Mo),and vanadium(V).The overall objective of this project is to develop a hydrometallurgical process that
