采用简单的化学共沉淀法制得负载铁锰氧化物的磁性粉末活性炭(MACCs),对其物理特性进行了表征,并利用序批式反应装置研究了MACCs对水中磺胺甲恶唑(SMZ)的吸附去除效果。结果表明,MACCs具有与粉末活性炭相似的吸附性能,且具有良好的磁性,易于分离回收;MACCs的投加量和停留时间对处理效果影响较大,而搅拌速度的影响较小,当MACCs投加量>400 mg/L、停留时间为10 min时,对SMZ的去除率可达到100%。MACCs对SMZ的吸附容量较大,400 mg的MACCs可有效处理28 L、SMZ浓度为1 mg/L的水样。
The magnetic powder activated carbon (MACCs) loaded with ferromanganese oxide was prepared by simple chemical coprecipitation, and its physical properties were characterized. Sequencing batch reactor was used to study the adsorption of MACS to sulfamethoxazole (SMZ) in water Removal. The results showed that MACCs had similar adsorption properties to powdered activated carbon, and had good magnetic properties for easy separation and recovery. The addition of MACCs and residence time had a great effect on the treatment effect, but the effect of stirring speed was less. When MACCs were added The amount of> 400 mg / L, residence time of 10 min, the removal rate of SMZ up to 100%. MACCs had a larger adsorption capacity for SMZ. 400 mg MACCs were able to effectively treat 28 L water samples with 1 mg / L SMZ.
