抗生素作为一种典型的新污染物,在饮用水中的风险控制是近年来研究的热点.通过开展生产运营工况下粉末活性炭(PAC)吸附对原水中抗生素的控制技术研究,评估原水预处理工艺对抗生素的去除效果.结果表明,水源地原水中检出10 种抗生素,抗生素总质量浓度为 184.75～195.72 ng/L,主要为磺胺类和氯霉素类.在水源地PAC加注点投加 5～20 mg/L的PAC,水厂进厂原水CODMn 降低 5.39%～12.4%,抗生素总浓度均值降低 54.1%～95.8%,林可酰胺类抗生素可完全去除,磺胺类去除效果次之,氯霉素类去除效果相对较低.PAC吸附原水预处理可有效控制饮用水中抗生素类新污染物的风险.
Operation Management of Powdered Activated Carbon Adsorption for Antibiotics Emerging Contaminants Removal in Raw Water
As a typical emerging contaminant,the risk control of antibiotics in drinking water has been a hot research topic recently.This study investigated the removal of antibiotics through powdered activated carbon(PAC)adsorption under production and operation conditions,the effectiveness of raw water pretreatment on antibiotic removal was evaluated.The results showed that 10 antibiotics were detected in the raw water of water source,with the total mass concentration ranging from 184.75 ng/L to 195.72 ng/L.Sulfonamides and chloramphenicols were the main detected antibiotics.Addition of 5～20 mg/L PAC at the water source filling point,the CODMn concentration of raw water entering the water plant reduced 5.39%～12.4%,and the average total concentration of antibotics reduced 54.1%～95.8%.Lincosamide antibiotics were completely removed,followed by sulfonamides,while chloramphenicol removal demonstrates a relatively lower efficacy.The raw water pretreatment of PAC adsorption can effectively control the risk of antibiotics emerging contaminants in drinking water.
