摘要
介绍了移动床膜生物反应器(MBBR)的工作原理、特点以及在钢厂综合废水治理中的首次应用情况。运行实践表明,MBBR具有较强的抗负荷冲击能力,水质水量的剧烈波动不会引起出水水质的较大变化。软化处理后的钢厂综合废水经MBBR处理后,出水COD保持在10 mg/L左右,氨氮低于1 mg/L,pH值稳定在7～8,SS<5 mg/L,且对碱度的贡献约30 mg/L,保证了回用水水质。
It is introduced the work principle and features of the moving bed-film bioreactor and its first application in comprehensive waste water treatment of iron and steel business.It is showed from the practice that MBBR has strong ability to resist load compact,so the quality of outgoing water would not be affected by serious fluctuation of intake water＇s quality and quantity.The softened comprehensive waste water of steelmaking plant is treated with MBBR,and its outgoing water has COD at 10 mg/L level,ammonia and nitrogen lower than 1 mg/L,pH steady at 7 to 8,SS lower than 5 mg/L,and a contribution of basicity given with about 30 mg/L,the backwater quality gets guaranteed.
