摘要
对某钢铁厂焦化废水进行曝气吹脱10h,氨氮去除率达73.7%,然后用缺氧-SBR工艺处理焦化废水,进水浓度为COD1474mg/L、NH3-N826.8mg/L时,缺氧SRT10h,SBR曝气10h,沉降2h,出水COD186mg/L、NH3-N290.25mg/L,去除率分别达到87.83%、64.9%。
Ammonia removal of coking wastewater was up to 73.7% after 10h aeration;A-SBR was applied to treat coking wastewater ,the influent was COD 1474mg/L and NH_3-N 826.8 mg/L,anoxic SRT 10h,SBR aeration 10h and settling 2h,the effluent was COD 186mg/L、NH_3-N 290.25 mg/L and the removal was up to 87.83% and 64.9%.
