摘　　要：研究了温度、厌氧污泥接种量对酒糟液厌氧发酵过程中COD、p H值、产气率的影响.结果表明,各实验条件下,酒糟液的p H均呈现向中性的趋势变化;同一温度下,厌氧污泥接种量越高,酒糟液越容易发酵,且发酵越完全;温度对产气率的影响较大,当温度40℃时,产气率较高,且不同接种量条件下的产气率相差较大.在本实验条件下,温度为40℃、V(厌氧污泥)∶V(酒糟液)=4∶6时是酒糟液厌氧发酵的最适宜条件.This paper studies the temperatures and anaerobic sludge on the liquor distiller's grains anaerobicfermentation process of COD,p H value change and gas yield. Results show that under the experimental conditions,the p H value shows a gradual return to neutral trend. At the same temperature,the higher inoculation amount,thedistiller's grain is more easy to ferment,and more complete. The temperature has a great influence on the gasproduction rate. Temperature of 40 ℃ when the gas production rate is higher than the temperature of others and notunder the same conditions of inoculation quantity gas production rate varies greatly. Under the experimental conditions,we find when the temperature is 40 ℃,inoculation V_(Anaerobic sludge)∶V_(Wine Lees Liquid)= 4∶6 is the most suitable conditions forthe anaerobic fermentation of distiller's grain.
