摘要
通过以配制的城市垃圾和实验室堆肥装置,通过12d的堆肥,研究好氧堆肥渗滤液的成分,将其与新填埋渗滤液、成熟填埋渗滤液以及世界卫生组织标准（1984年）进行详细的比较。结果表明：堆肥渗滤液呈碱性,大于新填埋场和成熟填埋场渗滤液的pH;COD、NH4^＋ -N和BOD5等参数对比说明了一次堆肥过程较新填埋场发酵过程成熟,但没有成熟填埋场发酵更彻底;堆肥渗滤液是一种有机营养的废水,同时富含大量的微生物。
Physico-chemical analyses of aerobic composting in a Bench-scale test were determined after a 12d main composting process, basing on man-made municipal solid waste. Also, the comparison among composting leachate, landfilling leachate and World Health Organization standard was finished. The results could be carried out as follows： pH value of composting leachate was over 7, more than those of landfilling leachate; Comparison of COD、NH4^＋ -N and BOD5 indicated that the biodegradation was speeded up during main composting than those during landfilling; Composting leachate was chemooranotrophic wastewater and was rich in microorganism.
