摘要
以常州市某城市污水处理厂中克拉霉素、磺胺甲恶唑、土霉素和头孢他啶为研究对象,在现场调查的基础上搭建模拟装置研究SBR工艺对抗生素类污染物的去除效果,并考察了污泥龄、水力停留时间、p H值、曝气等因素对去除效果的影响。研究发现,城市污水处理系统对克拉霉素、磺胺甲恶唑、土霉素和头孢他啶的去除率分别为91%、20%、96%和74%,SRT、HRT、p H值和曝气量对抗生素类污染物的去除有一定影响,同种抗生素污染物去除效果因不同影响因素而异,同一个因素的影响程度也因抗生素种类而异。
The removal of antibiotic pollutants like clarithromycin, sulfamethoxazole, oxytetracycline and ceftazidime in a municipal sewage treatment plant in Changzhou City was studied in the SBR process through the simulator built on the basis of site investigation. The effects of SRT, HRT, pH and aeration on the removal efficiency were investigated. The results showed that the removal rates of clarithromycin, sulfamethoxazole, oxytetracycline and ceftazidime were 91%, 20%, 96% and 74% respectively. SRT, HRT, pH and aeration all had impacts on the removal of antibiotic pollutants. The removal efficiencies of the same antibiotic pollutants varied due to different factors, and the impact degree of the same factor varied due to different antibiotic pollutants.
