除臭菌株对NH3和H2S释放及物质转化的影响
Effect of Deodorization Microorganisms on Release of NH3 and H2S and Matter Transformation
摘要
Abstract
In this study, the deodorization strains for cow mattle compost were selected by hyperthermia and ammonia sequential domestication, these strains's effect on release amount of NH3 and H2S and matter transformation were investigated.Deodorization strains B1 and A1 showed the best effect on deodorization, the total release amount of NH3 decreased by 68.59％ and 61.00％ compared to control, NH4+-N just increased by 4.47％ and 7.19％, NO3-N increased slightly, organic nitrogen increased by 28.99％ and 27.42％, and total nitrogen increased by 19.81％ and 18.80％ respectively, the result indicated that deodorization strains can not only stimulate nitrogen transformation, from inorganic nitrogen into organic nitrogen, but also reduce nitrogen loss effectively; Total release amount of H2S decreased by 89.69％ and 86.88％ compared to control, sulfate increased by 40.77％, 36.49％ and total sulphur content increased by 40.77％, 36.49％ respectively, the experimental result showed that deodorization strains promoted transformation of sulfate and reduced sulphur loss.The correlation analysis showed that release amount of NH3 had a extremely significant positive correlation with release amount of H2S and pH and a negative correlation with total nitrogen, organic nitrogen and sulfate.Release amount of H2S had a significant positive correlation with pH and a negative correlation wih total sulphur and sulfate.The analysis of variance showed that release amount of NH3 and H2S for treatment and control had a significant difference,the results displayed that deodorization strains can control release of NH3 and H2S on cow mattle compost effectively, and keeping nitrogen and sulphur.关键词
