二级好氧工艺处理炼油废水的研究

针对我国多数炼油企业所采用的处理工艺对炼油废水降解效果差，对其进行二级好氧生化试验，研究不同参数下的处理效果。结果表明：COD的降解率达到70％以上；Oil的降解率达到90％以上；NH3-N的降解率达到80％以上；且废水达到国家一级排放标准：COD〈60mg／L；BOD＜20mg／L；Oil〈5mg/L；NH3-N〈15mg／L；pH=6～9。

Study on Treating Refinery Wastewater with Two-stage Aerobiosis Technology

The processing craft which uses in view of our country Most Refinery Enterprises is bad to the refinery wastewater degeneration effect, carry on two-stage aerobiosis biochemistry experiment to it, study under the different parameters the processing effect. The result indicated： The COD degeneration rate achieves above 70 % The Oil degeneration rate achieves above 9,0 %; The NH3-N degeneration rate achieves above 80 %; And the wastewater reaching grade 1 of integrated wastewater discharge standard： COD〈60 mg/L： BOD〈20 mg/L; Oi1〈5 mg/L; NH3-N〈15 mg/L; pH = 6-9.
