在可降解城市生活垃圾厌氧消化器中添加玉米棒的效果研究

扎迪 ·锡

摘要


本研究以玉米棒补充可降解城市固体废物(MSW)厌氧消化池的效益。这是一项旨在使MSW厌氧消化器更可靠的努
力，通过生产连续和足够的气体，为预期的应用。该研究在实验室中进行，使用富蛋白MSW和富碳水化合物的玉米玉米芯在
中温消化器中进行，为期10天。MSW和玉米玉米芯的共消化可以测定原料组成，从而确定最大产气率的最佳混合比。MSW
和玉米穗按3：1、1：1和2：1的比例消化，MSW和玉米独立消化为对照。厌氧消化的关键成分碳氮比得到了极大的提高。
考虑到原料独立消化的沼气产量和共消化的沼气产量，在MSW中加入部分玉米棒子以改善厌氧条件是经济的。人们还注意
到，最终产物（沼气）的组成受到MSW的性质和组成的影响。MSW和玉米玉米芯以2：1的比例混合被证明产生最高数量的
气体，也是最好的气体组成，因此更好的气体质量。
