微生物菌剂-磷酸对猪粪水氨气减排最优参数研究
Research for ammonia gas emission reduction from pig slurry by microbial agents-phosphoric acid
摘要
Abstract
The research was to explore the effects,application scenarios and technical processes of the combined application of microbial agents and phosphoric acid on ammonia gas emission reduction and nitrogen loss during the storage of slurry.A three-factor,three-level orthogonal experiment was designed,including pH levels,microbial agents amounts and moisture content in the slurry.By analyzing the basic physicochemical properties of the slurry,the cumulative ammonia gas emissions,and the loss rates of ammonium nitrogen and total nitrogen,the optimal application scenarios and process parameters were comprehensively evaluated.The results indicated that the maximum concentration of ammonia gas emissions reached 6.3 mg·m-3,with cumulative emissions ranging from 17.07 to 121.14 mg,influenced in order by initial pH,solid content,and the amount of microbial agent added.The optimal parameters were as followed:Initial pH of 5.5,microbial agent addition of 1.6 g·L-1,and solid content of 2%.The loss rates of ammonium nitrogen and total nitrogen ranged from 2.08%to 58.28%and from 13.31%to 55.88%,respectively,influenced in order by initial pH,the amount of microbial agent added,and the solid content of the slurry,with optimal parameters being an initial pH of 5.5,microbial agent addition of 3 g·L-1,and solid content of 5%.In conclusion,microbial agent-phosphoric acid is more suitable for reducing nitrogen loss and ammonia emission from manure with low solid content.The optimal technical parameters are initial pH adjustment of 5.5 and microbial agent addition of 1.6 g∙L-1.关键词
