What is the principle of chemical treatment of phosphorus-containing wastewater?

At present, there are two kinds of chemical phosphorus removal, because some phosphorus in wastewater is hypophosphite and cannot be removed by precipitation of metal salts. It should be precipitated in homogeneous phase by hypophosphite remover P3. If it is orthophosphate, it is calcium salt precipitation. HMC-P3 is a dephosphorizing agent for hypophosphite wastewater developed by environmental researchers in Zhan Qing. It can combine with hypophosphite in water by homogeneous precipitation technology to generate insoluble precipitation, and the total phosphorus is below 0.5 mg/L. It is a dephosphorizing agent for treating hypophosphite wastewater in chemical plating, phosphorus chemical industry and other industries.
