目前我省农村部分地区,为了解决沼气池出料难的问题,在沼气池的进料口增设预处理池。人畜粪便、农作物秸秆等发酵原料在进入沼气池之前,先经预处理池浸泡,沼气池只进水不进渣。这样做,虽然解决了出料难的问题,但经我们调查、试验和分析认为:增设预处理池,原料浪费大,得不偿失。权衡利弊,很有商榷的必要。 At present, some areas in rural areas of our province, in order to solve the difficult problem of digester discharge, the digester feed inlet additional pre-treatment pool. Human and animal feces, crop straws and other fermentation raw materials into the digester, the first pre-treatment tank soak, digester only water does not enter the slag. In doing so, although the problem of difficult materials discharging was solved, our investigation, experiment and analysis indicated that the addition of pretreatment tanks would cost a lot of raw materials and was worth the candle. Weigh the pros and cons, it is necessary to discuss.
