PURPOSE: A method for removing nitrogen and perchlorate in wastewater is provided to prevent river contamination, and to remove the nitrogen and the perchlorate effectively with good economical efficiency. CONSTITUTION: A method for removing nitrogen and perchlorate in wastewater includes the following steps of supplying raw waste water and carbon sources compostion to a storage tank(10); collecting the wastewater to a pH adjusting tank(30); neutralizing the wastewater in a range of pH 6.5~8 by supplying acid or alkali liquid in the pH adjusting tank; removing nitrogen oxide and the perchlorate in the wastewater by injecting wastewater to an anoxic chamber(40); oxidizing ammoniacal nitrogen(NH4-N) to nitrate nitrogen(NO3^-, NO2^-); and discharging and trasnferring the wastewater to the anoxic chamber or to the outside. |
