摘要
分析了油库污水处理方法各自的特点,详细介绍了油库污水处理工艺现状,指出目前污水处理存在排水质量不稳定,废水中石油类、SS等污染物超标;污水中含有大量的BOD5和大量致病菌;且石油类、SS等污染物的数据严重超标,造成含油污水排放超标和活性炭过滤器被堵塞等问题。针对存在问题提出增加气浮净水器和增加SBR反应池对现有工艺进行改进,经工程实践运行表明,工艺具有处理效果好、运行稳定等特点,各项污染物指标均可达GB 8978-1996《污水综合排放标准》中的一级排放标准,是一种值得推广的有效治理含油废水的处理工艺。
Analyzed are characteristics of all kinds of oil depot waste water treatment methods,introduced is the current situation of waste water treatment process and it is pointed out that such problems as unstable quality and too much petroliferous,SS and other pollutants exist in waste water treatment and a large number of BOD5 and pathogenic bacteria exist in waste water,which will result in oily waste water discharge and blockage of active carbon filter.To solve these problems,air float purifier and SBR reaction pool are added to renovate the old process.The operational results show that this new process can operate properly and has good effect.All pollutant indexes in waste water treated by adopting this process can meet the Grade I discharge standard in the Integrated Waste Water Discharge Standards(GB8978-1996).
