【目的】膜生物反应器(MBR)工艺因其出水水质好和占地面积小等优点在城镇污水处理领域(尤其是地下污水处理厂)应用广泛,但膜材质固有缺陷引发的长期运行问题(高断丝率、膜通量衰减、出水水质波动),成为制约MBR发展的首要影响因素,且导致其工艺投资及运行成本均较高。【方法】华南地区某市政污水厂MBR运营人员通过优化工艺调控策略,将设计寿命为5年的中空纤维超滤膜的实际运行寿命延长至10年,且该批MBR出水水质优于一级A标准,并未出现明显的截留效能下降问题 ...

We demonstrate how oxygen‐deficient ruthenium oxide (RuOx) nanoparticles confined within covalent organic framework achieve highly efficient nitrate‐to‐ammonia conversion. Strong interaction between RuOx nanoparticles and COF results in modified interfacial hydrogen‐bond water network and adsorption of nitrogenous intermediates.
