摘要
从生态系统角度分析了影响有机固体废弃物好氧堆肥的生态因子及其调控措施。堆肥实质上是微生物在适宜条件下对有机物进行分解代谢的过程,伴随着细菌、真菌和放线菌等的动态变化。详细叙述了影响堆肥的生物因子———微生物及其调控措施,非生物因子———温度、含水率、含氧量、有机质含量与碳氮比、pH值、有害物质浓度及其调控措施。系统考虑堆肥生态因子及其调控措施,有助于优化堆肥条件。
The ecological factors and their regulation during the organic solid waste composting were analyzed from the view point of ecosystem. The essential of composting is the process of the decomposition and metabolism of the microbes in feasible conditions, accompanying the dynamic variation of bacteria, fungi, and actinomycetes. The details of biological factors, microbes, and non - biological fators, including temperature, moisture content, oxygen content, organic matter and carbon and nitrogen ratio, pH value, and toxic matter concerntration, and their regulation were presented. It is conducive to optimizing the process of eomposting to systematically considering ecological factors and their regulation during the organic solid waste eomposting.
