Abstract:

总结了新加坡樟宜回用水处理厂4次采样的结果,该厂日处理城市污水80万t.在好氧区很好地实现了部分硝化和亚硝酸盐积累,其中好氧氨氧化率平均为72.2%,亚硝酸盐积累率平均为76.0%.在缺氧区氨氮和亚硝酸盐得到了同步去除(厌氧氨氧化).物料衡算结果表明:初沉池的出水总氮的37.5%是通过自养脱氮去除,27.1%是通过传统的硝化/反硝化脱氮去除,其余部分总氮则存在于活性污泥和出水中.微生物和动力学研究表明:短悬浮或游离的厌氧氨氧化菌可存在于污泥龄较短的污水处理系统.最后从出水氮质量浓度、pH、碱度、曝气能耗及反应器容积等方面,将樟宜回用水处理厂的分段进水活性污泥法工艺与新加坡其他3个回用水处理厂的MEL/LE工艺进行了对比分析.
