摘要
为了提高A/O工艺的脱氮效果 ,采用悬浮填料生物系统来处理炼油废水。试验结果表明 ,当装填 30 %反应器容积的悬浮填料、进水NH3-N和COD分别为 5 475mg/L和 4 2 0 5 70mg/L、水力停留时间为 2 4h时 ,对NH3-N和COD的去除率分别达 96 %和 88%以上 ,出水水质达到了排放标准。此外 。
In order to improve the efficiency of ammonium nitrogen removal by A/O process,a bio-system with suspended carrier was adopt to treat oil-refined wastewater.Experimental result shows that when packed 30% of reactor volume with suspended carrier,the removal efficiency of NH_3-N,COD reach 96% and 88% respectively under the influent NH_3-N of 54-75 mg/L,COD of 420-570 mg/L along with hydraulic retention time of 24 h.The quality of effluent meets the corresponding wastewater discharge standard.In addition,simultaneous nitrification and denitrification (SND) phenomena appeared in aeration tank with suspended carrier.
