Ezperimental Study on Reducing Leachate Production by Saw Powder Adding

摘要：

In order to study the effect of saw powder on reducing leachate production, accelerating degradation of rubbish, COD and NH3-N concentration of leachate, three cylinder reactors for anaerobic landfill disposal were made to simulate the operation of landfill. In the experiment, leachate quantity, settling height of rubbish layer, COD and NH3-N concentration were monitored. The results of experimental data analysis show that saw powder has strong effect on reducing leachate quantity and accelerating degradation of rubbish. In 60 days, saw powder mixed in rubbish layer can reduce 1200-1300 mL leachate for liter rubbish, moreover, rubbish layer which saw powder mixed in settled more 5cm than rubbish layer which no saw powder mixed in. The experimental results indicate that saw powder can reduce COD concentration of leachate and adsorb NH3-N too.
