The aim of this work was to study the biological treatment of a synthetic wastewater containing emerging contaminants. The 95‐day experiment was conducted in an 81 L continuous flow conventional activated sludge apparatus consisting of anoxic and aerobic reactors with internal recycling, and a clarifier with activated sludge recycling. Real activated sludge from the municipal wastewater treatment plant in the Nur‐Sultan city was used. The degradation efficiencies of caffeine, metronidazole, and ibuprofen in the synthetic wastewater were studied either separately or in combination.

咖啡因，甲硝唑和布洛芬对连续流活性污泥过程的影响

这项工作的目的是研究含有新兴污染物的合成废水的生物处理。95天的实验是在81 L连续流常规活性污泥装置中进行的，该装置由内部循环的缺氧和好氧反应器以及具有活性污泥循环的澄清池组成。使用了来自努尔苏丹市市政废水处理厂的实际活性污泥。分别或联合研究了咖啡因，甲硝唑和布洛芬在合成废水中的降解效率。
