活性炭吸附处理垃圾渗滤液生物处理后尾水的实验研究

Experimental Study on the Activated Carbon Adsorption Treatment of Landfill Leachate after Biological Treatment

本实验以桂林市冲口垃圾填埋场垃圾渗滤液经生物处理后的尾水为水样,用活性炭对其进行吸附处理。实验研究结果表明,当活性炭投加量为8 g/L,吸附时间为40 min,吸附温度为35℃时,水样经吸附处理后CODCr和色度分别为为88 mg/L和30倍,出水水质达到了《生活垃圾填埋场污染控制标准》(GB16889-2008)中水污染物排放浓度限值的要求。

Taking landfill leachate after biological treatment of Guilin Chongkou landfill as water sample was treated with activated carbon adsorption. The results showed that when activated carbon dosage was 8 g/L, adsorption time was 40 rain, adsorption temperature was 35℃, the CODcr concentration and chroma of landfill leachate after treatment were 8 mg/L and 30, which reached the requirements of Standard for Pollution Control on the Landfill Site of Municipal Solid Waste （ GB16889 - 2008）.
