摘　　要：近年来,以生物质燃烧发电及产热为主要应用的产业发展迅速,随之产生的副产品生物灰的量也在逐年剧增,如何以更加绿色环保、经济易行的方式对这些生物灰进行有效地综合利用逐渐成为研究的热点.生物灰是一类碱性物质,除含有Si、Ca、Na、K、Mg、C、O、P、Cl等营养元素外,同时也可能含有多种微量元素Cu、Fe、Zn、Mn、Ni、Cr、Al、Ti和一定量的有害元素Cd、Pb、As、Hg等;其表面普遍存在形貌各异的不规则粒子,以褐色、灰白色、灰褐色、黄色为主,具有质轻细小,疏松多孔的特点.本文在对生物灰理化特性综合分析的基础上,根据其应用状况将生物灰的利用分为土壤改良剂、肥料、建筑材料、吸附剂、陶瓷添加剂、催化剂、以及其他应用,对其在国内外应用的研究现状进行了较全面的归纳.概述了生物灰在土壤改良剂、肥料、建筑材料、吸附剂、陶瓷添加剂、催化剂等方面的应用状况,分析了其优势和不足之处,同时对生物灰将来的应用前景进行了分析和展望.另外,还简要总结了超富集植物燃烧灰应用的研究现状.Recently, the electricity and heat production from biomass combustion have been rapidly developed. As a by-product from these industrials, biomass ash is suffering from the great increase of annual production. If biomass ash could not be used efficiently, it will become a new pollution source and cause great waste. The comprehensive utilization of biomass ash has gradually become a hot spot for researchers. As a kind of alkaline substance, biomass ash consists of the nutrients of Si, Ca, Na, K, Mg, C, O, P and C1, trace elements of Cu, Fe, Zn, Mn, Ni, Cr, A1 and Ti, and a certain amount harmful elements of Cd, Pb, As, Hg and so on. The biomass ash is usually shown in color of brown, gray, taupe and yellow. The morphology of biomass ash is porous with irregular particles on the surface. In this review, the utilizations of biomass ash in the fields of soil conditioner, building materials, adsorbents, ceramic additives, and catalysts were summarized. The advantages and disadvantages of the utilization of biomass ash were discussed. The application prospects of biomass ash were proposed and would provide useful information for the further researches. In addition, the development of hyperaccumulation plants burning ash was briefly summarized.
