摘要
为了研究在各种有机污染物存在的条件下对沸石去除氨氮能力的影响,以此来确定沸石对含有不同有机污染物废水的适用范围。本文通过静态和动态吸附实验,了解了腐殖酸、柠檬酸、淀粉和苯酚对沸石吸附氨氮的影响。实验表明,溶液中不同的有机物对沸石去除氨氮有不同的影响,沸石去除氨氮量有不同程度的下降。
Ammonia adsorption from simulated wastewater by natural zeolites in the presence of organic contaminants was investigated.The results showed that the presence of different organic compounds(including humic acid,citric acid,phenol and farina) slacked the uptake of ammonium ion onto the zeolites.The removal efficiencies decreased.
