【Abstract】 This article explains that the factory, with dried sweet potato as the main production material and annual production output of ten thousand ton alcohol, adopts the advanced technologies such as biological anaerobic, facultative oxygen digestion, aerobic, physical and chemical treatment etc. to comprehensively control the distiller’s residue liquid, on the basis of research, successful practical experiences as well as full and accurate data and process flow. The engineering system of the process can realize daily disposal capacity of high concentration organic sewage of 400～500 tons with COD, BOD and SS degradation purification rates above 99% and the drainage reaching the second grade drainage standard for the second class pollutants stipulated in the GB8978-1996. The biogas produced per year is 2.55～2.7 million cubic meters, which can obtain direct economic benefit of more than 2.6 million yuan RMB.更多还原
