摘要
某炼油厂300 m^(3)/h污水处理装置受进水水质COD、氨氮波动大影响,污水总排无法满足《石油炼制工业污染物排放标准》(GB31570-2015)的要求,针对排放标准及总排排放不合格影响因素,通过对原工艺预处理单元、生化氧化单元升级改造,改造后污水总排水满足《石油炼制工业污染物排放标准》(GB31570-2015)要求并平稳合格排放。
The 300 m^(3)/h wastewater treatment plant of a refinery was greatly affected by the fluctuation of COD and ammonia-nitrogen in the influent,and the total discharge of wastewater could not meet the"Emission standards of pollutants for petroleum refining industry"(GB31570-2015).In view of the emission standard and the unqualified influencing factors of the total discharge,the total sewage discharge got through the upgrading and reconstruction of original process pretreatment unit and the biochemical oxidation unit,which met the"Emission standards of pollutants for petroleum refining industry"(GB31570-2015)and discharged steadily.
