National "12th Five-Year" Plan for Science & Technology Support “Research and demonstration of high-quality biogas production 

equipment by centralized and combined digestion”;

The basic principle: through years of exploration and development of Hangzhou can master a set of mature and high ammonia methanogenic bacteria 

      domestication method, the ammonia nitrogen in anaerobic fermentation system tolerance concentration by conventional 3000mg/L to 6000mg/L,to 

      solve the technical problems of the world high nitrogen materials in anaerobic fermentation process easily pure ammonia poisoning chicken manure, 

      the process has been in a number of domestic and foreign large-scale biogas project in thesuccessful application and stable operation.

Technical features: ①High ammonia tolerance: raise ammonia tolerance level to 6000mg/L, 2 times of the conventional tolerance concentration (3000mg/L) ;

     ②High TS content digestion: TS content of anaerobic digestion can be as high as 8%-12%, which increase significantly gas production rate.

     Shandong Minhe (Phase I) 3MW biogas power generation project;Beijing DQY 2MW Biogas Power Generation Project.
