| 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6 000 mg·L~(-1)左右、pH=2.2时,铁炭微电解反应50 min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H_2O_2(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.

| Abstract: | The oxytetracycline wastcwater was treated by combined techniques of ferric-carbon microelectrolysis, Fenton reagent and biological contact oxidation .The results shown tbat the removal ratio of COD can be about 40％ in the condition tbat original COD is about 6 000 mg · L~-and pH=2.2 and time of fenic-carbon inner electrolysis reaction is 50 min. Then after adding 220 mg·L~(-1) H_2O_2(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. |
