摘　　要：采用SBR工艺对高盐度海产品加工废水进行了试验研究,结果表明,海产品加工废水中氯离子浓度不超过10000mg/L的情况下,采用具有一定耐盐度冲击负荷能力的SBR工艺是可行的;当进水中COD_(Cr)浓度为700～1000mg/L、NH4+-N浓度为80～120mg/L、[Cl-]≤8000mg/L的情况下,出水COD_(Cr)、NH3-N去除率分别为77.9%～81.2%、69.5%～76.6%,当进水中氯离子浓度继续增加,系统受盐度的影响加剧,处理效果变差。Sequencing biological reactor is adopted to treat high-salinity wastewater of processing marine products.The results show that it is feasible to treat the wastewater in which the proportion of seawater is no more than 50 percent and sequencing biological reactor can resist the high-salinity impact load.When the influent COD_(Cr) =700～ 1 000 mg/L,NH_3-N=80～120 mg/L and [Cl-]≤ 8 000 mg/L,the removal rates of both COD_(Cr) and NH_3-N in the effluent are 77.9%～81.2% and 69.5%～76.6% respectively.With the increasing of [Cl-],the SBR system is affected seriously and treating effect is worsened.
