National "12th Five-Year" Plan for Science & Technology Support “Research and demonstration of high-quality biogas production equipment by centralized and combined digestion”
Through years of exploration and development, Hangneng masters a set of mature and high ammonia methanogenic bacteria domestication method, the ammonia nitrogen in anaerobic fermentation system tolerance concentration increase from conventional 3000mg/L to 6000mg/L and it solved the worldwide technical problems of ammonia nitrogen poisoning during anaerobic fermentation of high nitrogen content materials such as pure chicken manure. The process has been applied in a number of domestic and foreign large-scale biogas project successfully application and operation is stable.
① High ammonia nitrogen tolerance: the ammonia nitrogen tolerance concentration of anaerobic fermentation bacteria was increased to 6,000mg/L which is double of the conventional tolerance concentration (3,000mg/L);
② High fermentation concentration: anaerobic fermentation concentration (TS) can be as high as 8%~12%, and gas production rate significantly improved.
Scope of application
Suitable for high ammonia concentration of raw materials fermentation, such as pure chicken manure, human manure, industrial organic waste.
Taiwan Shi 'an Farm 0.8mw Chicken Manure Bio-methane Power Generation Project;
Shandong Minhe Phase I 3MW Bio-methane Project;
Beijing Deqingyuan 2MW Bio-methane Project.
