摘　　要：以新型高效填料固定微生物 ,用生物接触氧化法处理难降解的炼油废水。通过观察废水中NH+ 4- N的去除情况 ,发现废水中存在一些物质抑制硝化细菌的活性。实验还发现在 COD≥ 50 0mg/ L的废水中 ,生物膜内异养细菌并不影响硝化细菌的代谢。最后用生物接触氧化工艺高效且稳定地同时把废水中 COD和 NH+ 4- N去除了 ,负荷较现场分别提高 2倍和WT5”BZ]Inhibitors that obstructed the activity of biofilms were found.If the COD Cr was less than 500 mg/L,the heterofrophic bascteria didnt inhibit the nitrification.Finally,bio contact oxidation process was used to treat refinery wastewater.It was steady to remove simultaneously COD Cr and NH + 4-N with high efficiencies.The removal rates for COD Cr and NH + 4-N were improved 2 times and 15 times respectively than the ASP.
