摘要
以上海某生活垃圾中转站为考察对象,系统监测和分析垃圾渗滤液主要水质指标在不同季节(冬季和夏季)的变化规律。结果表明:冬季渗滤液中pH值,COD,TOC和TN明显高于夏季,而NH+4-N,NO-2-N,NO-3-N,TSS和VSS则差别不大。渗滤液中可溶性有机物主要为色氨酸类蛋白物质,表明可生化性高,且冬季优于夏季。
This study investigated the variation of major physical-chemical properties of MSW leachate from a refuse transfer station in Shanghai under winter and summer conditions. The results show that pH,COD,TOC and TN in the leachate from winter are higher than summer,whereas NH＋4-N,NO-2-N,NO-3-N,TSS and VSS perform insignificant difference between two seasons. Tryptophan protein-like substances are the main dissolved organic matters in the leachate,indicating its high biodegradability,especially for winter.
