危险废物安全填埋场渗滤液处理试验研究

Experimental Study on the Treatment of Leachate from a Hazardous Waste Secure Landfill

采用聚铁混凝和 H2 O2 - Fe2 +催化氧化二级串联法对某危险废物安全填埋场渗滤液进行处理试验。结果表明 ,在适宜条件下 ,渗滤液 COD和色度的去除率可分别达到 88.3%和98% 。

The leachate from a hazardous waste secure landfill was treated by a two stage process of coagulation with polyferric sulfate and catalytic oxidation with H 2O 2-Fe 2+ .The results show that the removal rate of its COD and colourity are 88.3% and 98% respectively,arsenic content can reach undetected level under the optimum conditions.
