摘要
介绍了西安市第三污水处理厂工艺流程,对其运行情况进行比较分析,为氧化沟升级改造提供依据.数据表明,第三污水处理厂运行稳定,Orbal氧化沟工艺具有较强的抗冲击负荷能力,出水水质较为稳定.该工艺对污染物COD、T-N、NH3-N和TP的去除率分别为95%,90%,95%和90%,出水达标,部分指标明显优于排放标准.
The process of NO. 3 Wastewater Treatment in Xi＇an is introduced,and the operation ~s ana- lyzed. This can provide the basis for upgrading oxidation ditch. The results show that Orbal process has strong resistance to impact load ability andthe effluent quality is more stable. This process of pollutants COD, TN, NH3-N and TP total removal rate reached 95%, 90%, 95% and 90% respectively. The ef- fluent is obviously superior to wastewater discharge standard.
