该工程位于甘肃省天水国家农业科技园区,由专业开发沼气的天水润德沼气开发工程有限公司投资兴建并运营,并于2014年将沼气利用方式由沼气发电改为向农户集中供气。工程采用二级CSTR工艺,建有厌氧发酵罐6200 m~3(两座1600m~3一次发酵罐,两座1500m~3二次发酵罐)、1200 m~3储气柜、年产2万t的有机肥生产线及自动化控制设备,铺设了2 000多户供气主管网并在村口配套建设增压设施。工程以园区及周边废弃秸秆和粪污为原料生产沼
The project is located in Tianshui National Agricultural Science and Technology Park in Gansu Province. It was invested and built by Tianshun Runde Biogas Development Engineering Co., Ltd., a professional biogas producer. In 2014, the project shifted the use of biogas from biogas to centralized gas supply to farmers. The project uses a two-stage CSTR process with an anaerobic fermentation tank of 6200 m ~ 3 (two 1600 m ~ 3 primary fermentors and two 1500 m ~ 3 secondary fermentors) and 1200 m ~ 3 gas storage tanks with an annual output of 20,000 t organic fertilizer production lines and automated control equipment, laying more than 2,000 gas supply pipe network and supporting the construction of booster facilities in the village. The project uses abandoned straw and dung as raw materials in the park and the surrounding area to produce the marsh
