摘要
本研究对沸石进行氯化钠浸渍处理,再通过超声波技术进行复合改性,进一步考察沸石吸附性能随吸附时间、温度等因素的影响,比较了人工沸石与复合改性沸石对氨氮吸附性能的优劣。结果表明,在沸石投加量为50g/L、吸附时间60min、25℃条件下,联合功率为200W的超声波强化后,氨氮吸附性能可提升至92%以上。
In this study,the zeolite was modified by NaCl impregnation,then modified by ultrasonic technology.Then,the effects of adsorption time and temperature on adsorption ability of modified zeolite were studied.Also,Comparison of the adsorption properties was done between artificial zeolite and modified zeolite.The results show that the adsorption performance can increase to92%under the condition of50g/L zeolite dosage,60minutes adsorption time and200W joint power of ultrasonic intensification.
