Abstract:

针对干清粪式养猪废水浓度高和低C/N比的特点构建了四格室木质填料床A/O处理系统,通过调控运行探讨其除氮效能和机制。结果表明,在HRT18.7h、32℃、硝化液回流比200%、好氧区DO1.5mg·L-1等条件下,即便进水高达307.7mg·L-1,COD/TN平均为0.47,系统对COD、和TN的去除率仍能维持在66.5%、93.6%和89.0%左右,TN去除负荷达到0.22kg·m-3·d-1以上。系统对COD和TN的去除表现出一定的空间分区特征,其中前三厌氧格室是去除COD主要功能区,末端好氧格室是脱氮功能区。系统的脱氮机制以短程硝化反硝化为主,枯木填料的腐解为反硝化提供了必要的碳源。
