“三分建池,七分管理”,冬天要沼气池保持一定的产气率,关键是要搞好越冬管理。特别是对原来一些维修好的病池,以及当年一些未有“三结合”配套(即:猪圈、厕所、牛栏)的新建池尤为重要。现根据群众总结出来的办法有如下几点: (一)清除池内的化肥沉渣,换进新原料。一般在清池时,要留四分之一的沉渣作为菌种。换进新料,要经过堆沤,其中人粪便10％,畜粪、树叶、青草等40％入池,然后加进池塘污水50％。这样,沼气菌种得到新鲜营养物质后,便逐渐发育繁殖起来,到封冻前,由于池内温度的关系,它的繁殖盛期还在持续,这样就可以发挥沼气菌的内因作用多产气。 “One-third construction pool, seven management” in winter to maintain a certain biogas production rate, the key is to do a good job in winter management. In particular, it is particularly important for some newly repaired ponds and the newly built ponds that were not equipped with “triple combination” facilities (ie pigsty, toilets and oxen) during the year. Now summarized according to the masses out of the following points: (A) to clear the pool of fertilizer sediment, into a new raw material. Generally in the Qing pool, to stay a quarter of sediment as a strain. Change into the new material, to go through heap, where 10% of manure, livestock manure, leaves, grass and other 40% into the pool, and then added to the pond 50% of sewage. In this way, biogas species get fresh nutrients, they gradually develop and reproduce up to freezing, due to the relationship between the temperature in the pool, its breeding period is still continuing, so that you can play a biogas internal effects of more gas.
