摘　　要：利用核桃壳、木屑、甘蔗渣、水葫芦4种生物质作为吸附剂吸附处理餐饮废水,分析表征这4种材料的本体特性,考察生物质投加量、吸附时间、pH值和生物质粒径等因素对COD去除率及油的吸附量的影响。研究表明:生物质中纤维素与木质素的比值越高、比表面积越大吸附性能越好。4种吸附材料对COD去除率从大到小的顺序为甘蔗渣、水葫芦、木屑、核桃壳;对油的吸附量从大到小的顺序为水葫芦、木屑、甘蔗渣、核桃壳。Restaurant wastewater was treated by adsorbents,which were walnut shells,sawdust,bagasse,water hyacinth.Characterization was made on the main characteristics of these four kinds of materials,the impact of biomass dosage,adsorption time,pH,and biomass particle size and other factors on the adsorption of COD removal and oil were examined.Studies have shown that：the higher the ratio of cellulose and lignin in biomass,the greater the adsorption surface area,and the better the performance.Four kinds of adsorption material for COD removal in descending order is bagasse,water hyacinth,wood chips,walnut shell; the adsorption amount of oil in descending order is water hyacinth,sawdust,bagasse,walnut shell.
