垃圾渗滤液的COD与TOC相关性研究

目的]研究通过测定垃圾渗滤液TOC来预测COD的可行性。方法]测定国内不同地区7个垃圾填埋场的TOC和COD值,通过文献获得不同地区的TOC和COD数据。利用MS Modeling 4.0中的线性回归方法建立TOC与COD的关系方程,分析TOC和COD的相关关系。结果]结果表明,COD与TOC具有较好的相关性。可通过测定TOC来预测COD值,快速了解垃圾渗滤液的有机污染程度。结论]TOC的测定具有快速、准确、不产生二次污染的特点,对垃圾渗滤液处理工程的运行管理提供指导。

Study on the Correlation between TOC and COD of Landfill Leachate

Objective]The research aimed to study the feasibility of predicting COD by determining TOC of landfill leachate.Method] The some data of TOC and COD of landfill leachate in different regions was measured and obtained from literature.The TOC and COD correlation model was founded using linear regression statistics of MS modeling 4.0 software.Result] The results showed that correlation was very good between the TOC and the COD.The TOC could be used as a parameter for rapid estimation of COD to grasp the organic pollution degree of landfill leachate.Conclusion] Mensuration of TOC is rapid,accurate and have no secondary pollution,and can provide the guidance to operation of landfill leachate treatment work.
