摘　　要：通过开发一种新型酒糟稻壳分离技术,对酒糟进行洗浆-筛分-压榨处理,进一步提高酒糟的厌氧发酵效率。考察了酒糟浆液含固率、洗浆废水COD、洗浆温度以及搅拌时间对有机质分离率的影响,并验证了稻壳分离处理后有机质浆液的厌氧发酵性能。研究结果表明酒糟浆液含固率为8%,洗浆废水COD在500 mg·L^(-1)以下,搅拌时间为15 min时,可获得较好的分离效果,有机质分离率最高可达89.1%。同时,经过稻壳分离处理后有机质浆液的总固体(TS)产气率为621.02 L·kg^(-1)较酒糟浆液直接发酵高70%。In this study, a new type of distiller’s grains rice husk separation technology was developed, and the anaerobic fermentation efficiency of distiller’s grains was further improved by washing-screening-pressing the distiller’s grains. The effects of solid content of distiller’s grains slurry, COD of pulp washing wastewater, pulp washing temperature and stirring time on the separation rate of organic matter were investigated, and the anaerobic fermentation performance of the organic matter slurry after separation of rice husks was verified. The research results show that the solid content of the distiller’s grains slurry is 8%, the COD of the pulp washing wastewater is below 500 mg·L^(-1), and the stirring time is 15min. At the same time, the total solids(TS) gas production rate of the organic matter slurry after rice husk separation treatment was 621.02 L·kg^(-1), which was 70% higher than that of the direct fermentation of the distiller’s grains slurry.
