| 中文摘要 |
| 用内填YDT弹性立体填料的水解(酸化)-缺氧-好氧固定床生物膜系统处理焦化废水。结果表明:当进水COD和NH3-N浓度分别为1065mg/L和253mg/L,系统水力停留时间(HRT)为33.5h,混合液回流比为3.6时,出水COD约为180mg/L,NH3-N为5mg/L,COD和NH3-N的去除率分别达83%和98%。 |
| 英文摘要 |
| An acid hydrolysis- anaerobic-aerobic fixed biofilm system filled with a YDT elasto-steric pocking was used to treat wastewater from coking plant. The results show that when the system was operated with an influent in which the concentrations of COD and NH3-N were 1065 mg/L and 253 mg/L respectively, a total hydraulic residence time (HRT) of 33.5 h, and a mixed liquor recirculating ratio of 3.6, then there was an effluent with a COD concentration of about 180 mg/L and a NH3-N concentration of 5 mg/L, namely that the removals of COD and NH3-N were up to 83% and 98%, respectively. |
