摘    要:研究了微生物调控对有机生活废物堆肥的理化性质影响,结果表明:添加微生物处理比对照处理提前1 d进入高温分解期,且高温(>50℃)持续时间为6 d,较对照处理的长3 d;pH呈先升高后降低的趋势,微生物处理的pH值对照处理的偏低;EC值呈"M"型变化规律,微生物处理的EC值较对照高;在整个堆肥过程中微生物处理的胡敏酸E 4/E 6值都低于对照,表明添加菌剂有利于生活垃圾腐殖化;以发芽指数GI均大于80%这一标准评判,微生物处理比对照提前8d腐熟.

关 键 词:微生物  有机废物堆肥  理化性质

Abstract:The static composting experiments, with and without adding microbial agents, were conducted to investigate the effect of microbial control on the physicochemical properties of organic waste compost.The variation of temperature, pH, EC, E 4/E 6 and GI during composting was measured .Results showed that adding microbial treatment compared with the control was ahead 1 d into the pyrolysis stage,and maintained high temperature ( >50℃) for 6 days,3 d longer compared to the control treatment . The pH was increased first and then decreased during the composting process and lower pH value of microbial treatment compared with the control treatment.EC value was"M" type of variation, higher than the control microbial treatment .E4/E6 value of in the whole process of composting are lower than the control, indicating that the added agents conduced MSW humidification.Microbial treatment compared with the control was ahead 8 d maturity, by GI ( >80%) of the standard evaluation.
Keywords:microbes  organic waste compost  physicochemical properties
