摘要
随着人们生活水平的日益提高。生活中产生的固体废弃物越来越多,其中的有机物含量也越来越高。固体废弃物不仅影响环境卫生,而且广泛传播疾病。菌肥是利用废弃物中的有机物经生物化学转换,进行好氧或厌氧作用,在条件控制下,将废弃物中有机质分解、腐熟,使有机物转换成似腐殖质土。为解决生活固体废弃物以及污泥对环境的污染问题,开展废物利用,为绿色农业提供新型、环保、高效的微生物菌肥,利用生活垃圾以及污泥混合物为原料,接入有机物料腐熟固体混合菌剂和有益菌群混合菌悬液,生产微生物菌肥。以温度及有机碳含量（TOC）为测定指标,在菌肥发酵过程优化上,对混合菌剂接种量、含水率、C/N比、通风量等4方面进行了研究,确定了最佳工艺参数：菌剂接种总量1%,含水率55%,C/N 30：1,通风量0.2～0.4 m^3/min。优化工艺得到的菌肥产品经质量鉴定,优于国家标准。
Along with the continuous upgrading of people＇s living standard, more and more municipal solid waste （MSW） is generated from human daily life while the contents of organic matter herein getting higher. Such waste not only does great harm to nature, but also spread with various diseases. To minimise the environmental impairment, recycling the municipal solid waste and sludge through aerobic or anaerobic process to bio-chemically convert the organic matter to humus soil under controlled condition could be the way to provide a kind of new environmentally friendly and highly effective microbial fertilizer for green agriculture. The fermentation process of digesting organics by complex beneficial microbial community was optimised. Taking temperature and total organic carbon （TOC） as indicators, a series of best fermentation process parameters have been found out, i.e., 1% inoculation of microbial community, 55% water content, 30：1 of the carbon to nitrogen ratio, and ventilation at a rate of 0.2-0.4 m^3/min per cubic metre stacking. The optimised process has resulted in the compost product quality superior to the standard with 10^8- 10^10 of beneficial microbial population per gramme.
