摘要
采用直接光照处理青山垃圾填埋场和流芳垃圾填埋场的渗滤液,结果表明,直接光照处理4h,COD去除率分别为31%和18%,其主要原因在于青山垃圾填埋场中含有较多Fe和Cu等光催化物质及自身的光降解.直接光照对NH3-N和总-N的处理效果不佳.
The landfill leachate was treated by a light irradiation method in this experiment. The result shows that the COD removal rates after 4h irradiation were 31% for the leachate of Qingshan landfill compared and 18% for those of Liufang landfill, the main reason is the leachate of Qingshan landfill contains more Fe^3＋ and Cu^2＋ than those of Liufang landfill leachate. Light irradiation method has no remarked effect on the NH3-N and total-N removal.
