一、勤检查、勤分析、勤维修。根据群众多年使用沼气的经验,笔者总结出了一套分析判断病态池“病因”(主要是非发酵原因)的方法:①沼气池投料后,不能正常产气,压力始终未超过某一数值,此类池为漏气池;②每天要加几担水方可用1—3餐,此类池为漏水池;③进料后一直未产气,池内水位无变化,此类池为漏气池;④平时产气正常,突然气压降为零,以后不再回升,此类既漏气又漏水,很可能破裂;⑤
First, ground inspection, ground analysis, ground maintenance. According to the masses’ experience in using biogas for many years, the author summed up a set of methods for analyzing and judging the “cause” of the pathological pool (mainly the cause of non-fermentation): ① After the biogas feed, the gas can not be normally produced and the pressure does not exceed a certain value all the time Class pool for the leaky pool; ② a day to add a few water can be used 1-3 meals a day, such pools for the leaking pool; ③ has not been produced after the gas feed, the pool water level unchanged, such as leaking pool; ④ Normal gas production is normal, sudden pressure drop to zero, no longer pick up, such both leakage and leakage, is likely to rupture; ⑤
