农村家用沼气池的管理,采用“料液循环出稠留稀”的管理方法是行之有效的,能达到长期用气的目的,深受群众欢迎。所谓“料液循环,出稠留稀”,就是将出料间的料液取出后,经循环沟(在出料口旁砌一暗沟通向进料口或厕所粪坑内),流入主池,利用主池与出料间的压差和水位不同,将稠料压入出料间内,再用出渣器具取出稠料,留存稀料。其作法是:在池内没有浮渣和结壳的情况下,每隔1—2天,用粪舀子或粪桶,从出料间取出料液,直至出现稠料为止,一般取5—10桶(依浓度大小而定),再用出渣器具捞取稠料,其数量按同时进料数为准,保持合
Rural household biogas digesters management, the use of “liquid circulation thick lean” management method is effective, to achieve long-term use of gas, welcomed by the masses. The so-called “feed liquid circulation, out of thick dilute,” is the material between the discharge after the removal of the material, the circulation through the ditch (in the discharge port next to a dark ditch built into the feed port or toilet pit), into the main pool, The use of the main pool and the pressure difference between the discharge and water level, the thick material pressed into the discharge room, and then take out the thick residue slag discharge device, retained thinner. The practice is: in the pool without scum and crust cases, every 1-2 days, with feces scoops or manure bucket, remove the feed liquid from the discharge until the thick material so far, generally take 5-10 Barrels (depending on the concentration of size), and then take out slag residue thick materials, the number of feed at the same time subject to the number of keeping together
