METHOD FOR WATCHING AT THE REAL TIME INFLOW OF MATERIALS OBSTRUCTING OF NITRATION

摘要

PURPOSE: A method for monitoring inflow of nitrification inhibitor using DO(dissolved oxygen) for monitoring pollutant discharging. CONSTITUTION: A method for monitoring inflow of nitrification inhibitor comprises: a step of collecting test water and storing in a reaction container(20) which is used in measuring DO(dissolved oxygen); a step of stirring the test water; a step of measuring DO of the test water by signal from a DO sensor(21); a step of determining if the measured DO value is more than aeration set point; a step of calculating differential value of the measured DO value; a step of determining if DO value is within the range of set point which is judged harmful; a step of discharging the test water from the reaction container when DO differential value is within the range of set point; and a step of alarming that the test water contains nitrification inhibitor if DO value is out of set point.
