我省靖远、武威、张掖、玉门、金塔等地近两年来陆续办起糠醛厂,采用玉米蕊(穗轴)、稀硫酸等原料,加工提取糠醛。其中,仅张掖市小河糠醛厂提取糠醛后每年出渣(即糠醛渣)一万多吨,无法合理利用。经我们化验测定表明:糠醛渣中含有机物质78.60％,全氮0.49％,全磷0.30％,游离酸5.60％,pH2.5。为了开发利用糠醛渣中的有机质和氮、磷成份,提高综合利用效 In the past two years, Jingyuan, Wuwei, Zhangye, Yumen and Jinta of our province have started using furfural plants one after another. The raw materials such as corn kernel (cob) and dilute sulfuric acid are used to extract and extract furfural. Among them, only the small river furfural plant in Zhangye City extracted furfural annual residue (ie, furfural residue) more than 10,000 tons, can not be used properly. The results of our laboratory tests showed that furfural residue contained 78.60% organic matter, 0.49% total nitrogen, 0.30% total phosphorus, 5.60% free acid and pH2.5. In order to develop the use of furfural residue in the organic matter and nitrogen and phosphorus, improve the comprehensive utilization efficiency
