过去我在粪便发酵制造沼气的实验中,碰了几次钉子都没有制成功。最近我在科学画报六月份的小实验室的制造沼气的实验中,得到了一些启发,使我在五天之内,制出了几千毫升足够好几个班课堂实验用的沼气。仅将这一方法介绍如下:在池沼中取污泥一杯,马粪十斤,苏打粉五克,混合均匀装入喷雾器中,然后加入足够的水份,使喷雾器被水充满。把喷雾器各部份用蜡密封,仅留排气口接连橡皮管。橡皮管的另一端与盛满水的储气瓶相连
In the past, when I experimented with biogas fermentation in the excrement, I did not make any success with the nails. Recently I was inspired by the lab experiment in biogas production in the June Lab of Science Illustrated that within a five-day period, I made thousands of milliliters of enough biogas for classroom experiments. Only this method is introduced as follows: take a cup of mud in the ponds, horse manure ten pounds, five grams of soda, mixed evenly into the sprayer, and then add enough water to make the sprayer filled with water. Sprayer parts sealed with wax, leaving only the exhaust port rubber hose. The other end of the hose is connected to a tank full of water
