沼气池封闭不好给打压试验造成很大麻烦,特别是产气后漏气再封闭更困难。为了解决这个问题,去年在我县郝官乡刘屯村和东关乡孙白村用黄泥封闭7个沼气池(共14次),结果打压都一次成功,其主要做法是:一、选土过筛。选择粘合性强的黄粘土,把它放在日光下晒干,碾压碎过筛取其面。 Poor digester seal to the pressure test caused great trouble, especially after gas leak and then closed more difficult. In order to solve this problem, in last year in our county Hao official Township Liu Tun Village and East Township Sun Bai Cun Huangdi closed seven digesters (a total of 14 times), the results are a successful suppression, the main approach is: First, the election soil Sieve. Select the strong adhesion of yellow clay, put it in the sun dried, crushed and sieved to remove the surface.
