垃圾填埋场渗滤液中COD,BOD_5的动态变化

Dynamics of COD and BOD 5 in Leaching Liquor of Landfill

通过对某垃圾填埋场渗滤液的为期１年的监测，结果表明，垃圾渗滤液中含有大量的污染物质。在垃圾填埋场内设置三级沉淀池，能使污染物质含量有所降低，但仍不能达到排放标准的要求，排入环境的垃圾渗滤液对环境水质引起较严重的污染．

The authors monitored leaching liquor of a landfill for one year. Results show that there are many contaminants with high concentration in leaching liquor. Leaching liquor goes through some depositing tanks which are arranged as three grades. Concentrations deposited of some contaminants become low, but they are still higher than discharging standards of domestic wastewater. The leaching liquor pollutes surface water environment seriously.
