分别使用玉米秸秆与菌糠作为餐厨垃圾的堆肥调理剂,进行堆肥1次发酵对比试验,旨在考察菌糠作为餐厨垃圾堆肥调理剂的可行性.通过对2种调理剂与餐厨垃圾堆肥过程中理化性质及腐熟度变化的分析,表明餐厨垃圾好氧堆肥时,菌糠是一种优于玉米秸秆的良好调理剂,餐厨垃圾与菌糠混合堆肥时升温速度快、高温期持续时间长,含水率与有机质分别下降19.6%和20.2%.同时,其混合堆料在堆肥过程中散发臭气较少,1次堆肥处理后发芽指数较高(55.6%),基本实现腐熟.

The corn straws and spent mushroom substrate were utilized as the conditioner for composting of kitchen garbage. The physical and chemical properties as well as maturity changes during the composting processes were investigated. The result demonstrated that spent mushroom was superior to the corn straws during aerobic composting of kitchen garbage. The system could increase to the desired temperature within three days, under a long stable high-temperature period up to nine days, the moisture and organic substrates decreased 19.6% and 20.2%, respectively. Meanwhile, the composting of kitchen garbage mixed with spent mushroom had the merit of less odor production and higher germination index of 55.6% after the first composting treatment.
