  • 摘要: 海产品养殖及其加工废水成分复杂且含盐量大,因此处理难度大。采用兼养反硝化工艺在连续搅拌反应器(CSTR)中对其进行协同处理,以实现碳和氮的同步去除。分析不同盐度时自养和异养反硝化污泥的驯化情况,并研究兼养环境下,进水C/N和HRT对自养与异养反硝化协同/竞争作用的影响。结果表明:自养/异养反硝化污泥的3种驯化方式中驯化效率表现为高盐>低盐-高盐>无盐-低盐-高盐,高盐驯化方式利于脱氮系统的快速启动;在兼养环境下,HRT为8.0 h时$NO_{2}^{-}$的去除负荷和去除率分别可达0.3 kg/(m 3·d)和99.7%,C/N为5.0时$NO_{2}^{-}$及COD去除率分别为99.9%和99.0%,HRT为8.0 h和C/N为5.0的运行条件更利于兼养系统运行效能的提高。
