化学沉淀-硝化反硝化处理垃圾渗滤液试验研究

Study on the Treatment of Landfill Leachate by Chemical Precipitation and Nitrification Denitrification

垃圾渗滤液是一种难处理的高浓度含氮有机废水,本试验研究针对垃圾渗滤液氨氮浓度高的特点,采用化学沉淀联合硝化反硝化脱氮工艺,设计了反应器,并研究了该套工艺对垃圾渗滤液处理效果,试验表明:反应器对CODCr、NH3-N去除率分别达到了95%和90%以上,对垃圾渗滤液处理效果较好。

Landfill leachate is organic wastewater with high density nitrogen, which is difficult to deal with. The experiment was based on characteristic with high density nitrogen, adopting chemical precipitation and nitrification denitrification, designed relevant reactor, and study the process on the effect of landfill leachate. The results indicated the removal rate of CODer, NH3-N were more than 95 % and 90 %, the relevant reactor was fit to treat landfill leachate.
