Properties and Disposal of Municipal Solid Waste Incineration Fly Ash

Incineration has been used to dispose municipal solid waste(MSW) in the world.Attention is paid to the secondary pollution from municipal solid waste incineration(MSWI).Especially the safe and effective disposal of MSWI fly ash becomes an environmental and social problem which should be urgently resolved.The paper focuseds on the properties of MSW fly ash.The different kinds of technology of MSW fly ash are analysed in details.The main disposals of MSWI fly ash are filling,solidification and stabilization,and distilling heavy metals.The innocuous disposal of MSW fly ash which is compatible in China is impoldering advanced incinerator controlling the MSW and research effective and inexpensive stabilization chemicals and effective technique of distilling heavy metals to reduce the secondary pollution caused by the heavy metal of MSWI fly ash.     

土壤重金属污染修复植物处置技术进展

植物修复是一种环境友好、易操作且具有经济效益的土壤污染修复技术，其可用于土壤原位修复，但修复后会产生含大量重金属的植物，对修复植物的处置成为亟待解决的科学问题。本文对现有的修复植物处置方法进行了综述，如焚烧法、热解法、热液改质法等，探讨了各种方法的优缺点以及目前研究存在的问题，并对其中的热解法与热液改质法的未来研究方向进行了展望，以期为今后在实际应用中合理选择修复植物处置方法与资源化利用提供依据与参考。
