Detection device and method for measuring anaerobic ammonium oxidation activity

A detection method for measuring anaerobic ammonium oxidation activity, comprising:

• (1) performing an anaerobic ammonium oxidation reaction and a denitrification reaction on sludge to be tested in a first reaction chamber, and performing a denitrification reaction on the sludge to be tested in a second reaction chamber, wherein the denitrification reactions in the first reaction chamber and the second reaction chamber have the same rate;
• (2) controlling and recording, by a detector, flow rates of reagents entering the first reaction chamber and the second reaction chamber in a reaction process, ensuring that pH in the first reaction chamber and pH in the second reaction chamber are maintained at a constant and identical level;
• and
• (3) calculating a real-time consumption rate of hydrogen ions based on concentrations of the reagents added to the first reaction chamber and the second reaction chamber, the flow rate of the reagent entering the first reaction chamber, and the flow rate of the reagent entering the second reaction chamber, and obtaining a real-time ammonia nitrogen conversion rate in an anaerobic ammonium oxidation process according to a correspondence relationship between hydrogen ion consumption rates and ammonia nitrogen consumption rates, namely real-time activity of anaerobic ammonium oxidation.
