| Abstract: | 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. |
