Hypophosphites is oxidized to orthophosphates.The low-conversion of hypophosphites can also be verified from COD clearances, due to useless
Water TOC concentration substantially constants, it may infer that the COD in waste water is mainly contributed by hypophosphites, by 72 hours, COD was reduced
81%, the COD of reduction is primarily due to the oxidation of hypophosphites.Not oxidized hypophosphite concentration is appointed so more than 100ppm
(in terms of phosphorus), necessarily cause processed waste water total phosphorus exceeded.Although the extension reaction time can increase the oxygenation efficiency in hypophosphites,
