石油炼制—氮肥生产污水生化处理研究

Study on Biochemical Treatment of Sewage in Oil Refining-nitrogenous Fertilizer Production

石油炼制—氮肥生产污水二级生化处理时对CODcr、BOD5、石油类、挥发酚等污染物的降解效果是好的 ,但对氨氮 (NH3 -N)的降解效果就较差。培养降解的NH3 -N两个菌种 ,用于炼油—氮肥生产污水的硝化处理 。

The biochemical sewage secondary treatment toward the waste in petroleum refining-nitrogenous fertilizer production is effective to degrading COD cr ,BOD 5,oil,volatile and other pollutants,but has low effect on amino-nitrogen degradation.Two bacterium seeds are cultivated to degrade the amino-nitrogen, which brings about a striking effect.
