| 摘 要： | 广州市大坦沙污水处理厂采用A2/O工艺，合并处理城市生活污水和粪便污水，由于粪便污水的污染物含量高和水量不稳定等特点，对水厂的运行有不利的影响。实践表明：通过控制好氧池溶解氧、延长好氧段的水力停留时间、增大回流比和提高MLSS与污泥龄等措施，该厂取得较好的脱氮除磷效果，实现出水COD、总氮、氨氮和总磷达标排放。

| Abstract: | The A2/O process used to treat urban sewage combined with the fecal sewage was investigated in Datansha Sewage Treatment Plant in Guangzhou. Fecal sewage contained higher concentration of contaminants and non-steady influent flow and thus brought about unfavorable influence to the operation of this plant. The practical results showed that the better efficiency can be achieved through adjusting the operating procedures, including the control of DO level in the oxygen consuming tank, extending the hydraulic resident time, increasing the ratio of recycle, enhancing the MLSS and the sludge resident time, etc. After the application of these improvements, it can get better removal efficiency of nitrogen and phosphorus simultaneously. Besides, the COD, NH3-N, TN and TP in the effluent become lower than the discharge standard of pollutants for municipal wastewater. |
