改良SBR工艺处理造纸废水

Paper-making Wastewater Treatment by Improvement SBR

传统SBR系统对造纸废水有着较好的处理效果,但处理效果还不够理想。文章介绍了传统SBR系统的改良工艺——供气式低压射流曝气系统对造纸废水的处理工艺。对整个调试运行过程以及运行过程中出现的实际问题进行了详细的介绍和分析,并给出了相应的应对措施。运行结果表明,系统的处理能力14000 t/d,出水COD为76mg/L,SS为10 mg/L,BOD5为10 mg/L,出水水质达到造纸工业水污染排放国家标准(GB 3544-2008)。

Traditional SBR has good treatment effect to paper-making wastewater,but the efficiency is not enough meet needs.The improvement SBR was introduced in the paper,which is low pressure inject to treat paper-making wastewater.The whole experiment operation and the problems were introduced and analyzed,the according methods were given.The results showed that the treatment ability was 14000 t/d,the outlet COD was 76 mg/L,SS was 10 mg/L,BOD5 was 10 mg/L,water quality met the GB 3544-2008.
