CATALYTIC DENITRIFICATION PERFORMANCE OF SYGERGISTIC EFFECT OF Pd-Cu/GRAPHENE AND ZERO-VALENT IRON (Fe0)

  • 摘要: 为解决城市污水处理厂二级出水中硝态氮含量较高的问题,对Pd-Cu/石墨烯协同零价铁(Fe0)的新型催化反硝化法处理水体中NO3--N进行了深入研究,重点对催化反硝化操作条件进行了优化。研究发现,新型催化反硝化法获得较好催化效果的最佳运行条件为:Fe0投加量为4 g/L,m(Pd):m(Cu)为3:1,溶液pH为4.2,Pd-Cu/石墨烯投加量为4 g/L,反应时间为2 h,此时系统的NO3--N去除率及N2转化率分别为78%和74%。在催化反硝化反应中,Fe0主要以电子供体存在,其在一定的酸性条件下,可触发催化反应的发生。催化反应发生在催化剂的金属活性位(Pd和Cu)上。NO3--N在催化剂作用下,通过脱氧反应被逐步去除并转化为N2。此外,催化剂载体及催化反应中的传质效果也是影响催化效果的重要因素。
