Abstract

PURPOSE: To remove the organophosphoric cpd. in waste water through its effective transformation into inorganic substance by a method wherein mixture of waste water and active sludge is adjusted to specific pH and treated.
CONSTITUTION: The waste water contg. organophosphoric cpd. is treated with the active sludge, whereby the concentration of NaCl, if contained, is reduced to 1% or less, and the mixed liquid is adjusted to pH 5W7.5. The treatment in this way efficiently transforms organic phosphorus into inorganic substance in a short period of time. The formed inorganic phosphoric acid is taken as P-source by active sludge, thereby eliminating the need to provide new phosphate.
