| 中文摘要 |
| 采用水解酸化 反硝化 硝化的组合工艺对土霉素废水进行实验室规模连续处理 ,水解酸化和反硝化均采用上向流污泥床 ,硝化采用2个使用不同填料的生物膜反应器 ,稳定运行 70d .当进水COD和NH4+-N浓度分别为2200～3000mg/L和400～460mg/L时 ,该系统在总水力停留时间为56h的条件下 ,稳定实现80%以上的COD和TN去除率 .生物处理出水经48mg/L聚合硫酸铁(以铁计)处理后COD降至293mg/L,实现了废水的达标排放. |
| 英文摘要 |
| Successive hydrolysis-denitrification-nitrification process is adopted to treat terramycin wastewater in lab scale for 70 days. Two sludge bed reactors are used respectively for hydrolysis and denitrification, and two biofilm reactors are used for nitrification. When the COD and NH4+-N concentrations in influent were 2 200～3 000mg/L and 400～460mg/L, more than 80% COD and TN removals were achieved under a total HRT of 56h. The COD of the effluent was reduced to 293mg/L through coagulation under a polyferric sulfate dose of 48mg/L as Fe. |
