Abstract

近年来我国农林生物质直燃电厂发展迅速,日益增长的灰渣带来了越来越大的环境压力。生物质电厂灰渣是一类富有价值的可回收资源,亟待有效利用。有必要寻找一种合理的资源化手段整体处理灰渣。本研究综述了我国农林生物质直燃发电的发展现状、生物质灰渣的理化性质及其在基础设施建设、土壤修复改良、元素回收、吸附材料与复合材料制备等领域的应用,进而提出了依据灰渣粒径差异资源化处理电厂灰渣的一体化方案。不同粒径的生物质灰渣经过细分处理,可提高灰渣的资源利用率,有利于农林生物质直燃电厂的可持续发展。

In recent years, the agroforestry biomass-fired power plants have been developing rapidly in China. The growing ash and slag from these plants have brought an increasingly environmental pressure. The ash and slag are valuable and recyclable resources, which should be utilized efficiently. It is urgent to seek an integrated method for disposal of them. The present study summarized the development of agroforestry biomass-fired power plants, the physicochemical properties of ash and slag, and their applications in the field of infrastructure construction, soil improvement, element recycling, adsorption materials, and composite materials. Based on the different particle size distributions of ash and slag, an integrated scheme for the resource utilization was proposed. The biomass ash and slag would be subdivided with different particle sizes to improve their utilizations. It should be beneficial to the sustainable development of the agroforestry biomass-fired power plants.
