The utility model discloses a water quality nitrogen and phosphorus on-line monitoring system. At present, a common online detector in the market consumes long time from water inlet to data outlet, is poor in stability, reduces the efficiency and accuracy of detection index analysis, and is complex in structure and high in operation and maintenance cost. The device is characterized in that an outlet of a total nitrogen chromogenic reagent adding device is communicated with a dosing port of a total nitrogen reaction box, an outlet of a total phosphorus chromogenic reagent adding device is communicated with a dosing port of a total phosphorus reaction box, and an outlet of an ammonia nitrogen chromogenic reagent adding device is communicated with a dosing port of an ammonia nitrogen reaction box; an outlet of the total nitrogen reaction box is communicated with an inlet of the total nitrogen cuvette, an outlet of the total phosphorus reaction box is communicated with an inlet of the total phosphorus cuvette, an
