摘要
针对生物脱氮技术的缺点,对单纯零价铁及零价铁与生物耦合还原脱氮的效果、反应条件以及减少零价铁钝化现象的方法等进行了综述,以期为现有的污水处理厂升级改造提供理论依据和设计运行参数参考。同时为零价铁与生物耦合系统的研究方向提出了建议。
According to the disadvantages of biological denitrification technology, the reductive denitrification effect, reaction conditions and the methods for reducing passivation phenomenon of pure zero - value iron （ZVI） and ZVI - biological coupling system were summarized to provide upgrading theoretical basis and references of design and operation parameters for existing sewage treatment plants. The prospective research directions on ZVI- coupling system were also proposed in this review.
