根据微生物生长基本规律,搅拌能增进厌氧微生物与发酵底物的传质速度,增进厌氧微生物自身复状与富集,提高其生物活性。在沼气厌氧微生物发酵中还能促进气体产物的溢出,提高产气率和原料利率用。在沼气发酵中由于粪便、秸杆等有机底物与水的比重大不相同,要产生浮壳与沉渣,形成料液分层发酵。浮壳内水分少,微生物活性低,使
According to the basic rules of microbial growth, stirring can increase the rate of mass transfer of anaerobic microorganisms and fermentation substrates, enhance the rejuvenation and enrichment of anaerobic microorganisms, and enhance their biological activity. Biogas anaerobic fermentation in the gas can also promote the overflow of gas products, increase gas production rates and raw material rates. In biogas fermentation due to manure, straw and other organic substrates and water, the proportion of very different, to produce floating shell and sediment, the formation of liquid layered fermentation. Floating shell less water, microbial activity is low, so
