一个新建的户用沼气池正常启动需要3～7天,为此,用户应当做到以下几点: ——采取低浓度启动。第一次投料过多,不但原料容易变酸,而且排杂气时间长。适宜的发酵启动浓度应掌握在5％以内,8～10米~3的池子约投入1.5米~3的纯粪便。启动成功后再逐步加料,实行高浓度运转。——新池初次投料最好选用堆沤变黑了的牛粪,因为其中含有大量的沼气菌种。池温20℃以上,1～3天即可快速启动成功。——没有腐熟的牛粪,可将备好的发酵原料加入
It takes 3 to 7 days for a newly built household biogas digester to start up normally. To do this, the user should do the following: - Start with a low concentration. Excessive feeding for the first time, not only easy to sour raw materials, and exhaust a long time. Appropriate fermentation start-up concentration should be controlled within 5%, 8 ~ 10 m ~ 3 pool about 1.5 ~ 3 into the pure manure. After the successful start and then gradually feed, the implementation of high concentrations of operation. - The new pond is the best choice for the first batch of dumped black cattle manure, because it contains a large number of biogas species. Pool temperature above 20 ℃, 1 to 3 days to quickly start successfully. - No maturity of cow dung, can be prepared fermented raw materials added
