摘要
本试验采用缺氧-好氧生物脱氮系统对焦化废水进行了试验研究,并对影响硝化和反硝化效果的诸因素进行了考察.研究结果表明,该系统不仅能有效地去除废水中的氨氮,同时可去除COD 等物质.氨氮去除率为95～99.2%,COD 去除率为88～94%。
In this paper,an anoxic-aerobic Bio-Denitro process for treating coke plantwastewater is presented and the main factors of the nitrification and denitrificationare also discussed.The experimental results show that the process is not only capa-ble of removing NH_3-N from the wastewater effectively,but also can remove organ-ics measured as COD.The NH_3-N removal is 95～99.2% COD removal is88～94%.
