The invention discloses an
ammonium sulfate waste liquid treatment method and
evaporation and concentration equipment, and the treatment method comprises the following steps: S1, adding
ammonia water into
ammonium sulfate waste liquid, and then carrying out standing
sedimentation treatment; s2, overflowing and taking out part of supernate of the
ammonium sulfate waste liquid after standing and
settling, recording the taken-out supernate as R1, recording the remainder as R2, adding an organic-inorganic composite flocculant or a used organic-inorganic composite flocculant into R2, then stirring and filtering, and combining the filtered filtrate with R1 to obtain purified liquid; evaporating and concentrating the purified liquid to obtain a concentrated liquid; and performing centrifugal treatment on the concentrated solution, and performing
drying treatment on a centrifugal
solid to obtain an
ammonium sulfate product. According to the method,
ammonia water is added into the
ammonium sulfate waste liquid to adjust the pH value, so that
metal impurities can be settled, particles are too fine and are difficult to directly filter, after part of supernate is taken out, residues are flocculated by using an organic-inorganic composite flocculant, and then
filtration is performed, so that the
metal impurities can be settled, filtered and removed.
