COMPOSITE DENITRIFICATION SYSTEM PERFORMING A SULFUR AUTOTROPHIC DENITRIFICATION AND AN ELECTROCHEMICAL DENITRIFICATION PROCESSES

摘要

PURPOSE: A composite denitrification system is provided to effectively improve performance of denitrification while reducing processing costs for injecting methanol chemicals and guiding a dentrification process.;CONSTITUTION: A composite denitrification system discharges processed water which is biochemically processed, and is connected to an advanced sewage treatment system. A composite autotrophic denitrification tank(10) removes remaining nitrogen in the processed water by performing a dentrificatio nprocess and sulfur dentrification reaction. The composite autotrophic denitrification tank comprises a sulfur denitrification tank located on the bottom and a reaction column having an electrochemical denitrification tank located on the top of the system.;COPYRIGHT KIPO 2010
