Operation Management of Powdered Activated Carbon Adsorption for Antibiotics Emerging Contaminants Removal in Raw Water
摘要
Abstract
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.关键词
