摘  要:对某城市污水处理厂采用A2/O—MBR组合工艺去除几种典型药品及个人护理品(PPCPs)的效果进行了长期检测。结果表明,部分目标物的进水浓度呈现一定的季节性变化规律,对大部分目标物的去除效果相对稳定,其中对咖啡因、硫氰酸盐和避蚊胺的去除率达到80%以上,而舒必利、卡马西平和双氯酚酸等物质在工艺中几乎不能被去除。通过考察各种目标物沿工艺流程的浓度变化,发现目标物的迁移行为呈现出一定的规律性,根据这种规律性可将目标物划分为3类:在厌氧段迅速得到去除的物质(如咖啡因、避蚊胺、佳乐麝香和吐纳麝香)、沿程均匀去除的物质(如美托洛尔、甲氧苄安嘧啶和硫氰酸盐)以及在工艺中不易被去除的物质(如舒必利、卡马西平和双氯酚酸)。The removal of MBR process was investigated typical pharmaceuticals and personal care products (PPCPs) by A~/O in a wastewater treatment plant. The concentrations of several target PPCPs in the influent showed a seasonal variation. But most of the target compounds were removed at a stable rate during this investigation. The removal rates of caffeine, erythromycin and DEET were more than 80%. On the other hand, sulpiride, carbamazepine and diclofenac were hardly removed. The con- centration variation of the target PPCPs along the process was also investigated. The target PPCPs were divided into three groups according to their different behavioral characteristics: substances that could be removed effectively in the anaerobic tank such as caffeine, DEET, HHCB and AHTN; substances that could be removed uniformly along the process such as metoprolol, trimethoprim and erythromycin; and substances that could not be removed such as sulpiride, carbamazepine and diclofenac.
