摘　　要：采用了铁炭微电解-Fenton-生物接触氧化工艺对高浓度难生化处理的土霉素废水进行处理。结果表明,当原水COD在6000mg·L-1左右、pH=2.2时,铁炭微电解反应50min后COD的去除率达到40%,再对铁炭微电解出水投加质量浓度220mg·L-1的H2O2(30%)进行Fenton试剂法处理,COD的去除率达到75%以上,然后进入生物接触氧化反应池,出水能够达到排放标准。The oxytetracycline wastewater was treated by combined techniques of ferric-carbon microelectrolysis, Fenton reagent and biological contact oxidation .The results shown that the removal ratio of COD can be about 40% in the condition that original COD is about 6 000 mg·L^1 and pH=2.2 and time of ferric-carbon inner electrolysis reaction is 50 min. Then after adding 220 mg·L^-1 H2O：（30%） in per Liter wastewater, the removal ratio of COD becomes over 75%. Finally, wastewater that pretreated by above methods was treated by biological contact oxidation process .In the end; the final effluents can be suit for the national wastewater discharge standard.
