NOVELTY - Relieving ammonia nitrogen inhibition in high-concentration anaerobic fermentation reaction of rural domestic garbage involves adding metal-organic frameworks (MOFs) material derived metal oxide adsorbent into the anaerobic fermentation reaction system. USE - Method for relieving ammonia nitrogen inhibition in high-concentration anaerobic fermentation reaction of rural domestic garbage. ADVANTAGE - The ammonia nitrogen adsorption capacity of the method in an anaerobic digestion system reaches 95.02 mg/g, and ammonia nitrogen inhibition in high-concentration anaerobic fermentation is effectively relieved. The method is simple to operate, has good ammonia nitrogen removal effect, and normally operate in humid anaerobic fermentation environment, and has the characteristics of superparamagnetism, convenience in recovery and good economic benefit.
