Antibiotics and hormones in swine wastewater have become a critical concern worldwide due to the severe threats to human health and the eco-environment. Removal of most detectable antibiotics and hormones, such as sulfonamides (SAs), SMs, tetracyclines (TCs), macrolides, and estrogenic hormones from swine wastewater utilizing various biological processes were summarized and compared. In biological processes, biosorption and biodegradation are the two major removal mechanisms for antibiotics and hormones. The residuals in treated effluents and sludge of conventional activated sludge and anaerobic digestion processes can still pose risks to the surrounding environment, and the anaerobic processes' removal efficiencies were inferior to those of aerobic processes. In contrast, membrane bioreactors (MBRs), constructed wetlands (CWs) and modified processes performed better because of their higher biodegradation of toxicants. Process modification on activated sludge, anaerobic digestion and conventional MBRs could also enhance the performance (e.g. removing up to 98% SMs, 88.9% TCs, and 99.6% hormones from wastewater). The hybrid process combining MBRs with biological or physical technology also led to better removal efficiency. As such, modified conventional biological processes, advanced biological technologies and MBR hybrid systems are considered as a promising technology for removing toxicants from swine wastewater.
养猪废水中的抗生素和激素因其对人类健康和生态环境的严重威胁而成为全球关注的焦点。本文综述并比较了各种生物处理工艺对养猪废水中磺胺类（SAs）、SMs、四环素类（TCs）、大环内酯类和雌激素等大多数可检测抗生素和激素的去除效果。在生物处理过程中，生物吸附和生物降解是抗生素和激素的两种主要去除机制。传统活性污泥法和厌氧消化工艺处理废水中的残留物质和污泥仍会对周围环境构成威胁，且厌氧工艺的去除效率低于好氧工艺。相比之下，由于具有更高的毒物生物降解能力，膜生物反应器（MBRs）、人工湿地（CWs）和改良工艺的效果更好。对活性污泥法、厌氧消化和传统 MBR 进行工艺改良也可以提高（例如，从废水中去除高达 98%的 SMs、88.9%的 TCs 和 99.6%的激素）性能。MBR 与生物或物理技术相结合的混合工艺也可提高去除效率。因此，改良的传统生物工艺、先进的生物技术和 MBR 混合系统被认为是一种有前途的从养猪废水中去除毒物的技术。
