【摘要】 东深原水生物硝化工程采用生物接触氧化法对微污染原水进行处理 ,设计处理规模为40 0万m3/d。通过半年的试运行 ,可以初步认为 ,生物接触氧化工艺适于处理东深微污染原水 ,对氨氮去除率在 75 %以上 ,对其它 10多项水质指标也有不同程度的降解 ,基本达到设计要求更多还原

【Abstract】 The slightly polluted raw water of Dongjiang Shenzhen diverting canal is treated by biological denitrification process namely biological contact oxidation with design capacity of 4 million cubic meters per day. Through half year of commissioning operation a removal ratio up to 75% ammonia nitrogen, and also different levels of degradation for other ten indicators have been obtained. The expected target in design stage has been completed. It is believed that this process is suitable for the raw water in this case.更多还原
