摘要
本文以二相厌氧-生物接触氧化工艺对四环素废水的处理进行了试验研究,并考察了各反应器的运行特性。在进水COD浓度≤3500mg/L,四环素浓度≤230mg/L,二相厌氧中产酸相、产甲烷相及后续生物接触氧化反应器的水力停留时间分别为3、24h和10h时,COD去除率93％,四环素去除率96％,出水COD<230mg/L,生物接触氧化对氨氮的去除率为75％。试验结果表明二相厌氧-生物接触氧化工艺用于处理四环素废水是可行的。
In this paper, Tetracycline wastewater was treated by a two-phase anaerobic-contact oxidation process. The characteristics of reactors used in this process were also investigated,When the influent COD was less than 3500mg/L, Tetracycline concentration was less than 230mg/L HRTs of the acid phase, the methane phase and the contact oxidation were 3,24 and 10h, respectively, it was found that removal efficiencies of COD and Tetracycline were 93% and 96%, respectively, the effluent COD was less than 230mg/L, and NH_3-N removal in the contact oxidation was 75%.It was conclused that the two-phase anaerobic-contact oxidation process was feasible for treating Tetracycline wastwater.
