- 摘要:污水处理厂传统的二级生化处理对药品及个人护理用品(Pharmaceutical and Personal Care Products,PPCPs)等新兴污染物的去除率较低,PPCPs随出水排放会给生态环境带来较大的风险,并会经过生物富集最终危害到人体健康,因此需要通过进一步的深度净化以削减其风险.本文综述了常见PPCPs在污水处理系统的分布特征及生态风险,阐述了高级氧化工艺(Advanced oxidation processes,AOPs)、生物活性炭工艺(Biological activated carbon,BAC)以及高级氧化联合生物活性炭工艺(AOPs-BAC)深度净化PPCPs的净化原理,在此基础上,综述了AOPs-BAC工艺对污水中PPCPs的深度净化效果及主要影响因素,并探讨了AOPs-BAC工艺对污水中PPCPs的风险削减能力,为污水中PPCPs深度净化工艺的研发及PPCPs的生态风险控制提供了参考.
- Abstract:Emerging pollutants such as pharmaceutical and personal care products (PPCPs) are hardly removed by traditional secondary biochemical treatment processes in wastewater treatment plants. Greater ecological risks will be posed to the environment by PPCPs with the discharge of wastewater effluent, and PPCPs' bioaccumulation will ultimately endanger human health. So further deep purification techniques are needed to reduce the risk of PPCPs before entering into the environment. In this paper, the distribution characteristics and ecological risks of PPCPs in wastewater treatment are reviewed. Furthermore, The mechanism of treatments of PPCPs by advanced oxidation processes (AOPs), biological activated carbon (BAC), AOPs coupled with BAC technologies (AOPs-BAC) is described. On this basis, the application and main influencing factors of AOPs-BAC for advanced treatment of PPCPs are reviewed. What's more, the risk reduction ability of wastewater containing PPCPs by AOPs-BAC is summarized. This paper contributes not only to the development advanced treatment for removing PPCPs in wastewater, but also to the ecological risk control of PPCPs.
