摘要
通过对西安市第三污水处理厂Orbal氧化沟反硝化速率的测定分析,结果表明Orbal氧化沟外沟、中沟和内沟中的反硝化速率依次减小,且反硝化速率与SCOD成正比。研究分析了污水厂脱氮效率不高的原因,提出了相应的运行调整措施与建议,以确保Orbal氧化沟外沟的反硝化环境,从而提高系统的脱氮效果。
According to the study on the process of denitrification for Orbal Oxidation Ditch in No. 3 WWTP （Wasterwater Treatment Plant）of Xi＇an, the result shows that the rate of denitrification reduces in turn in the three ditch （ outside, middle and inside） of Orbal Oxidation Ditch. The test aslo shows that the rate of denitrification in direct proportion with the SCOD. The research has analyzed the reason of low denitrogenation efficiency in No. 3 WWTP of Xi＇an and proposed the corresponding operation measure and the suggestion that can guarantee denitrification environment of the outside ditch to get to high denitrogenation efficiency.
