| 摘 要： | 介绍了广饶县污水处理厂一期、二期工艺即淹没式生物膜工艺和改良式A2/O工艺的特点及运行情况,分析了每个阶段对污染物的去除原理,并进行对比。结果表明:1)两个工艺对有机物的去除效果相当;2)改良式A2/O工艺对TN的去除效果优于淹没式生物膜工艺,主要是因为改良式A2/O工艺增加了内回流,增强了反硝化效果;3)两个工艺对TP的去除效果相当。

| Abstract: | It is introduced the characteristics and the operating conditions of the first and second processes in the Guangrao Wastewater Treatment Plant,which are the submerged biofilm process and the modified A2/O process.And it is analyzed the removal principles of the contaminations,which are compared.The results show that:(1) the removal effects of organic matter are about the same;(2) the TN removal effect of the modified A2/O process is better than that of the submerged biofilm process,it is because that the modified A2/O process increases the internal reflux,and it strengthens the effect of denitrification;(3) the TP removal effects of two processes are about the same. |
