轧钢生产过程中会产生大量的废水,这些废水如果直接排放,不仅污染环境,而且造成水资源的严重浪费。因此,各轧钢厂需要对其废水进行处理,以达到国家轧钢废水排放标准或者厂内相应回用标准。

  该工艺在冷轧含油废水处理中应用较为广泛。超滤法是膜分离法中的一种,通过超滤可以有效去除含油废水中的SS和油类物质,生物接触氧化/生物滤池可以降解废水中大部分的COD,而在生物法后增加过滤或吸附工艺,可以进一步提高出水水质。超滤是一种新型含油废水处理技术,近几年在冷轧含油废水处理中应用广泛。超滤法原理是利用超滤膜,采用错流过滤的方式,在一定压差和紊流流动的情况下,使废水中大部分极性分子通过膜,而所有非极性分子(如胶体微粒)和相对分子质量较大的物质被截留,从而净化废水。超滤法具有分离效率高、能耗低、分离过程中无相变、出水油含量低、工艺本身不产生污泥、维护管理方便等优点,但也存在一次性投资大、膜易污染、难清洗、寿命短等缺点。超滤法的关键在于开发成本低、寿命长、易清洗、稳定性好的新型超滤膜。(3)超滤一MBR工艺:超滤一MBR工艺首先将含油废水经调节池调出水节后用纸带过滤机过滤,再进入超滤系统进行油水分离,超滤出水进入MBR进一步处理。该工艺处理效率高、出水水质好,但需要严格控制操作条件与工艺参数,减轻膜污染,提高膜组件的运行稳定性和处理能力。2.2.2含油废水处理现状:目前,国内冷轧含油废水中的SS和油类物质得到了较好的控制,但部分钢铁企业对COD的处理仍然达不到最新颁布的《钢铁工业水污染物排放标准》中对COD的排放要求。表2列出了国内部分钢铁冷轧含油废水的处理情况。
