二级好氧工艺用于炼油废水氨氮降解的试验研究

EXPERIMENTAL STUDY ON TWO STAGE AEROBIC TECHNIQUE IN THE AMMONICAL NITROGEN DEGRADATION OF REFINARY SEWAGE

通过对炼油废水处理工艺中氨氮降解效果差的原因分析，在大量试验研究的基础上，提出采用二级好氧工艺对炼油废水中的氨氮进行生物降解，试验结果证明，只要条件控制得当，便可保证处理水中的氨氮及其它各项污染物指标达到国家规定的排放标准。经过长时间的连续运行试验，确定出采用该工艺时所需控制的有关参数及运行条件。

Having analyzed the reasons that make the effects of ammonical nitrogen degradation so poor in the process of refinery sewage treatment, the authors put forward a new technique on the basis of a great deal of experimental researches. That is to adopt the Two stage Aerobic Technique to biodegrade the ammonical nitrogen in the refinery sewage. Experimental data show that the sewage can be ensured to be up to the standards of national discharging standards, if the associated conditions are adaquetely controlled. Through long continuous experimental running, all relevent parameters and operating conditions that need to be controlled in the technique can be determined.
