| 摘 要： | 缺氧-好氧系统(Anoxic/Oxic system简称A/O系统)是一项同时去碳与脱氮的废水处理新工艺。应用和推广A/O工艺处理含氮有机废水对水体氮污染的防治具有重要的现实意义。在人工合成废水的模型试验中,A/O系统污泥负荷以0.1～0.2公斤BOD_5/公斤MLSS天;进水BOD_5:TN>3:1为宜。在上述条件下,A/O系统总氮去除率可达60％以上。本文还提出了一些改善污泥沉降性能的方法。

| Abstract: | Anoxic/Oxic system (A/O) is a type of new process for wastewater treatment. Carbon and nitrogen can be removed simultaneously with this system. Using A/O process to treat organic wastewater involved nitrogen has an important practical significance for the prevention and treatment of water nitrogen pollution.
In synthetical wastewater pilot test, the optimal sludge load is 0.1-0.2 kg BOD_5/ kg MLSS. day; influent BOD_5: TN 3:1. Under this condition total nitrogen removal percentage of A/O system is higher than 60%. Some procedures that can improve the quality of sludge subsidence are also presented. |
