摘要
反应器填埋场很大程度上缩短了城市固体废物(MSW)的稳定化时间。渗滤液循环是实现反应器的有效途径不同渗滤液pH值条件下反应器的运行效率是不同的。本文采用两种缓冲剂,熟石灰和粉煤灰对渗滤液pH值进行调节,讨论它们对渗滤液回灌、废物稳定化的影响。同时,本文也分析了两种调节方法的区别。实验证明了调节后的环境有利于固体废物中有机污染物的去除,对金属离子和盐类没有明显去除作用。两种调节方案都是简单、经济可行的。
The stabilization period of municipal solid waste can be shortened greatly in bioreactor landfill.Leachate recycling, however.is an effective approach to bioreactor.The operation efficiencies are distinct in different pH conditions.Two kinds of pH buffers,lime and fly ash were used to adjust pH in the leachate,and the impacts on leachate recycle and waste stabilization were discussed.The differences imposed by two reagents were also analyzed at the same time.It is proved that the degradation of organic pollutants in enhanced in the environment altered,but the removal of metal ion and salts is ambiguous.Two ways are both accessible and economically practical.
