炼油污水NH_3—N降解机理与工艺研究

Study of Degradating Amino - nitrogen of Petuoleum - refining Sewage

炼油污水二级生化处理对CODcr、BOD5、石油类、挥发酚等污染物的降解效果是好的,但对NH3-N的降解效果就很差。本研究以培养降解NH3-N的10NG-1、10NG-2菌种,用于炼油污水NH3-N硝化处理,降解率达90％以上,获得显著效果。

The biochemical trtatment of petroleum - refining sewage.as atypical technigue to treat organic sewage with high concentration,is very effective to degradate CODcr,BOD,Ar -oH and other petroleum pollutants,but has little effect to amino- nitrogen degradntion. However. 10NC-1 and 10NG - 2 Iincrera cultivated for amino-nitrogen degrdation,which is studied in the article, can yield notable rosults in the treatment of petroleum - refining increasing the amino-nitrogendegradation rate up to 90%.
