改性凹凸棒土处理垃圾渗滤液中氨氮的实验研究OA北大核心CSCDCSTPCD
Research on Treatment of Ammonia-nitrogen of Landfill Leachate by Alter-attapuligite
采用NaCl和煅烧对凹凸棒土进行改性,研究改性凹凸棒土对洛阳市预处理后的垃圾渗滤液中氨氮的去除效果.对100 mL氨氮含量为97 mg/L的垃圾渗滤液的最佳吸附条件为:NaCl溶液浓度为10％,将预处理凹凸棒土在NaCl溶液中浸泡改性1h,干燥,煅烧500℃,调节水样的pH值为6,取改性凹凸棒土3.0g,吸附处理时间为40min,氨氮去除率可达94.8％.
Attapuligite was modified by NaCl and calcined. NH4+-N of landfill leachate in Luoyang was treated by alter-attapuligite. While the volume of the landfill leachate sample is 100 mL and its NH4+ -N concentration is 97 mg/L, the best adsorption conditions were the concentrate of NaCl solution is 10% , attapuligite immerse in NaCl solution modified 1 h, dry, calcined at 500 ℃ , pH value of landfill leachate is 6,the dosage of alter-attapuligit…查看全部>>
