污泥接种量和尿素对小麦秸秆厌氧发酵的影响
THE IMPACT OF SLUDGE INOCULUM AND UREA ON ANAEROBIC FERMENTATION OF WHEAT STRAW
摘要
Abstract
By setting three experimental groups and three comparative groups this paper studies the effects of sludge and urea on the anaerobic fermentation of the wheat straw. Using 100g of wheat straw as the raw material for fermentation, when in three experimental groups the inoculated sludge of ponds is 20g, 30g, 40g, the cumulative gas production is 1429ml, 2163ml and 2544ml, and the daily gas production is 59.54ml, 80.10ml and 94.20ml. After the added 2.0g of urea, the cumulative gas production is 3521ml, 4322ml and 5209ml, and the daily gas production is 140.84ml, 166.20ml and 192.90ml. The results show that with the increase of sludge inoculums, for fermenting wheat straw in experimental and comparative groups, the cumulative gas production increases significantly. Meanwhile, there is no gas production in the three experimental groups at the first day of the experiment, and the gas production comes to an end on the 27th day. However, there is the gas production in three comparative groups on the first day, and the gas production comes to an end on the 25th day. The results show that adding urea plays an important role in improving the gas production and shortening the straw fermentation cycle of the wheat straw.关键词
