COD, ammonia nitrogen, total phosphorus and total nitrogen in the water quality monitoring equipment are detected by a colorimetric method. Colorimetry (Colorimetry) is a method of determining the content of a component to be measured by comparing or measuring the depth of color of solutions of colored substances. There are two common colorimetry methods: visual colorimetry and photoelectric colorimetry are both based on lambert-beer's law. The common visual colorimetry is a standard series method, namely, different amounts of standard solutions of an object to be detected are used in a group of identical colorimetric tubes, color development is carried out according to an analysis step, and standard color levels with gradually changing colors are prepared. The sample solution is developed under the identical condition, and compared with the standard color level, the standard with the closest color is found visually, and the content of the component to be detected in the sample is calculated and determined according to the amount of the standard solution contained in the standard solution.
