MBBR工艺处理反渗透浓盐水中试研究

摘要

The effect of the process of moving bed biofilm reactor (MBBR) in treatment of reverse osmosis concentrated brine in steel industry was investigated through field pilot-scale experiment. The results showed that the effect of MBBR to remove ammonia nitrogen is very obvious, with the removal above 90%. The effect of COD removal by MBBR is also good, with the removal rate above 70%. This pilot experiment provided valuable experience for future practical engineering.%通过现场中试考察了MBBR工艺处理钢铁企业反渗透浓盐水的效果。中试结果表明，MBBR对于氨氮的去除效果明显，去除率稳定在90%以上；对浓盐水中COD也有很好的去除效果，去除率达70%以上。
