The rising occurrence of emerging contaminants in sludges both inhibits the anaerobic digestion of sludges and induces health issues when sludges are recycled in agriculture, calling for methods to remove contaminants. Here we review emerging pollutants in wastewater treatment plants, before and after anaerobic digestion. We present their inhibitory effects and remediation methods to alleviate inhibition. Pharmaceuticals have been detected in about 50% of the sludge samples. Sewage sludge contaminants include 19% of diuretics, 16–21% of lipid-modifying agents, hydrochlorothiazide, diclofenac, furosemide, clarithromycin, atorvastatin, and carbamazepine. Levels of antibiotics, azithromycin, ciprofloxacin, and estrone range from 500 to 600 ng/g in sludges from wastewater treatment plants. Remediation methods comprise electrooxidation, ultrasonication, thermal hydrolysis, ozonation, and bioaugmentation. Fermenting the sludges with acidogenic bacteria reduces the level of emerging pollutants in the supernatant. Nonetheless, liquid digestates still contains emerging pollutants such as sunscreen octocrylene at 147 ug/L and acetaminophen at 58.6 ug/L. As a result, pretreatment of sludge containing emerging pollutants is required.

污泥中新兴污染物的增加既抑制了污泥的厌氧消化，又在污泥在农业中回收时引发了健康问题，因此需要采取去除污染物的方法。在这里，我们回顾了厌氧消化前后污水处理厂中新出现的污染物。我们介绍了它们的抑制作用和缓解抑制的补救方法。大约 50% 的污泥样品中检测到药物。污水污泥污染物包括 19% 的利尿剂、16-21% 的脂质调节剂、氢氯噻嗪、双氯芬酸、速尿、克拉霉素、阿托伐他汀和卡马西平。废水处理厂污泥中抗生素、阿奇霉素、环丙沙星和雌酮的含量范围为 500 至 600 ng/g。修复方法包括电氧化法、超声波法、热水解、臭氧化和生物强化。用产酸细菌发酵污泥可降低上清液中新出现的污染物的水平。尽管如此，液体消化物仍然含有新出现的污染物，例如 147 ug/L 的防晒剂奥克立林和 58.6 ug/L 的对乙酰氨基酚。因此，需要对含有新兴污染物的污泥进行预处理。
