摘　　要：当前水体污染问题日趋严重,寻求高效、环保,且成本低廉的水处理剂一直以来是水处理技术研究中的重要方向之一。秸秆是一类农作物废弃物,材料中富含纤维素和木质素等天然高分子,来源十分广泛,且是一类可再生资源。然而目前过剩的秸秆材料大多仍是通过焚烧处理,这不仅给大气环境带来危害,还造成资源的极大浪费。将秸秆材料通过适当的处理和改性,作为水处理剂,应用于污水处理中,无疑具有重要的现实意义和经济价值。本文详细综述了近年来国内外就秸秆材料的改性处理方法及其在水处理中的应用研究情况。Recently, the problem of water pollution turns more and more serious, and it is one of the hottest research projects in the field of the wastewater treatment to search for the new technologies with the characteristics of high efficiency, low cost and nontoxicity. Straw materials are a type of crop wastes, which are rich in various natural polymer materials, such as cellulose and lignin. Furthermore, the resources of straw materials are not only abundant in nature, but renewable. However, until now, the usual treatment for the excess straws is still incineration, which is not only destruction of the atmospheric environment, but waste of resources. Undoubtedly, it is practical significance and economic value to apply the modified straw materials in wastewater treatment. In this paper, the modification methods for straw and their applications in wastewater treatment have been reviewed in detail.
