1981年我们在威海市江家寨新能源村进行了沼气池池型选择与固体发酵新工艺(也称于发酵)生产应用试验,当年三月开始建池,五、六月分别投料和运转,十月召开了专家评议会,确定两结合沼气池与固体发酵工艺适宜北方农村推广应用,该村已建两结合沼气池189口,采用固体发酵与水压池发酵相结合。威海市1983年进行全市扩大推广, In 1981, we conducted a biogas digester pool selection and solid fermentation new technology (also called fermentation) production and application test in New Energy Village, Jiangjiazhai, Weihai City. In March of the same year, we started to build a pond and dosed and operated in May and June separately. In October, an expert council was held to determine the feasibility of combining two biogas digesters and a solid fermentation process for the promotion and application of the rural northern areas. The village has built 189 dual-integrated biogas digesters, combining solid fermentation with hydraulic pooling. Weihai city in 1983 to expand the promotion,
