摘要
本文介绍了上海焦化厂废水经过塔式生物滤池处理后,采用两级上向流填料床A—A(Anoxic—Aerobic)处理系统进行脱氮和处理难降解有机物的试验研究。研究结果表明好氧—缺氧—好氧三级生物处理系统,处理焦化废水效果良好。在本试验条件下,总水力停留时间15h,回流比为5时,出水COD约100mg/L,NH_3—N<1mg/L,NO_T—N<8mg/L,它为焦化废水处理提供了新的技术途径。
This paper presents a laboratory scale study of two stage(anoxic aerobic)biological upflow media bed treatment system for nitrogen and organic compound control of coke plant wastewater. The results obtained demonstrated the technical feasibility of treating coke plant wastewater in the two-stage upflow biological media bed system. Under the operational conditions of this test;HRT=15h(total) ,r=5.thd high nitrogen and organic compound removal capcpilities may reach :CODcff≈100mg/L,NH3- Neff<1 mg/L,NO7-Neff< 8mg/L.
