牛粪炭灰和复合炭灰垫料对氨气吸附效果的研究OA

To address the issues of ammonia pollution and high bedding costs in large-scale dairy farms,this study utilized barn manure combustion ash as the primary material.The ammonia adsorption performance of pure ash bedding was compared with different composite beddings under simulated static barn conditions.Results showed that pure ash bedding performed best,with the shortest adsorption equilibrium time.Among composite beddings,ash-sawdust had the highest adsorption rate,yet remained lower than pure ash.These findings indicate that both pure and composite ash beddings have certain ammonia adsorption capabilities,providing a reference for ammonia control and bedding optimization on dairy farms.
