碱渣与生活垃圾混合填埋的实验研究

Experimental Study of Carbonate Residues and Urban Waste in Mixed Landfill

以碱渣(白泥)和生活垃圾按不同比例混合填埋,模拟真实垃圾填埋场的垃圾降解条件,进行垃圾降解实验以探索白泥存在对垃圾填埋场垃圾降解过程的影响。通过21周的室内模拟实验,垃圾填埋时填加白泥可以提高渗滤液出水的pH值和电导率DS值,降低出水的COD值。得出垃圾填埋时加入适量白泥是经济有效的固体废弃物处理处置方法的结论。

Experiment was made to simulate the real condition of waste decomposition in landfill by mixing white mud and urban waste in different proportion of mixture for the purpose to assess the impact of white mud on the composition of urban waste. With the indoor experimentation last for 21 weeks, pH and DS value of leachate were found rising while COD value became lower by adding white mud in the urban waste. It is concluded that adding white mud in waste landfill is an economic and effective method for solid waste management.
