混凝—臭氧氧化处理垃圾中转站渗滤液的试验研究

Treatment of the Landfill Leachate from waste transfer station by Coagulation-Ozonation Process

以垃圾中转站渗滤液为研究对象,分析了混凝-臭氧氧化工艺对渗滤液COD和色度的影响。结果表明:在pH=11.2,FeCl3加量为900mg/L,臭氧反应时间为20min,臭氧流量为35mg/L的优化条件下,垃圾中转站渗滤液的COD、色度分别可去除78.39%与95.34,BOD5/COD由反应之前的0.152提升到了0.415,可生化性明显改善。

The effect of coagulation-ozonation process on COD and chroma removal of leachate from waste transfer station was analyzed.The results showed that under the optimum conditions(900 mg/L of FeCl3,and pH 11.2,and 20 min ozone reaction time,and 35 mg/L of ozone flow rate),COD and chroma of leachate from waste transfer station could be removed by 78.39%and 95.34 respectively,and BOD5/COD increased from 0.152 to 0.415,indicating that the biodegradability was significantly enhanced.
