江都式三联合沼气池是对目前所推广的沼气池的一种改进。它在沼气池的进料口前增加了一个0.3米~3的“一隔二池”式的小蓄粪池。将厕所、猪圈、沼气池结合在一起。五年来,我们在江都县杨庄公社对这种改进式的沼气池(以下简称江都池)进行了反复的卫生学调查与实验观察,证明江都池比目前推广的沼气池有三方面的优点:(1)江都池将厕所、猪圈、沼气池三者结合在一起,由于人粪在“一隔二池”小蓄粪池中采用直管粪封法,既方便用户,又可减少蝇蛆孳生,有利于改善农村环境卫生。(2)增加了小蓄粪池,人粪可在其中进行初步无害化处理(一留二沉三发酵),增强了杀菌灭卵的效力(见表1)
Jiangdu three combined biogas digesters is an improvement to the current promotion of biogas digesters. It adds a 0.3 to 3 “one-second-pool” small septic tank in front of the biogas digester. The toilets, pigsty, digesters together. Over the past five years, we conducted repeated hygiene surveys and experimental observations on this improved biogas digester in Yangzhuang Commune, Jiangdu County, proving that Jiangdu Chi has three advantages over the currently-promoted biogas digesters: 1) Jiangdu pool combines toilets, pigsty and biogas tanks together. Since human waste is used in the “one-second-pool” small-scale manure storage tank, it is convenient for users and breeding of fly maggots , Is conducive to improving rural sanitation. (2) A small manure tank is added, in which human excrement can be preliminarily innocuously treated (one-second and three-sour fermentation), and the effectiveness of bactericidal and egg-shedding is enhanced (see Table 1)
