| 摘 要： | 通过对2005～2011年兴丰垃圾填埋场渗滤液中pH值、COD和BOD5浓度变化分析,结果表明:广州兴丰生活垃圾填埋场已提前进入"老龄化"阶段,自2009年以来渗滤液中pH值稳定在7.73～8.24之间,且有增大的趋势;COD和BOD5均有大幅度下降,但仍保持较高值,两者间有明显的相关性;BOD5/COD的值介于0.48～0.19之间,可生化性差。

| Abstract: | This article aims to explore the characteristics of Guangzhou Xingfong Landfill leachate, and pro- vides theoretical bases for technical transformation project. Through analysing the values of pH, COD and BOD： in Xingfeng landfill leachate from 2005 to 2009 ,the results show that：Guangzhou Xingfeng solid waste landfill has been advanced into the ＂aging＂ stage;pH has stabilized in the range of 7.73 to 8.2 since 2009, which has an increasing trend; COD and BOD5 are significantly decreased but remain at a high value, and there is a clear correlation between the two; the BOD5/COD range from 0.48 to 0. 19, and this poor biode- gradability may cause some difficulties in biochemical treatment of leachate. |
