[0002] Total phosphorus is the sum of all phosphorus forms in water, including orthophosphate, condensed phosphates, and organic phosphorus. Digestion is essential for determining the total phosphorus content in wastewater. To perform total phosphorus digestion, the wastewater is placed in a container and a specific digestion reagent, such as potassium persulfate, is added. The wastewater is then heated to convert the various phosphorus forms into measurable forms. After digestion, the wastewater is cooled, the volume is brought to a constant volume, and the total phosphorus content is determined using an appropriate method to ensure accurate and reliable results.

The total phosphorus digestion device designed in this application is a full glass structure, which will not introduce secondary pollution, is easy to operate, and can be used in conjunction with standard methods to determine the total phosphorus in water; in addition, the weight of the upper cover of the digestion device is used in this application to press the digestion tube plug; the guide edge on the upper cover is used to guide the water droplets along the "guide edge" along the wall of the "digestion tank body" to the "bottom of the digestion device tank", thereby discharging the digestion device, without affecting the digestion tube throughout the process.
