Abstract

Invenţia se referă la un procedeu de epurare a apelor uzate de la producţiile galvano-chimice de ioni de amoniu.Procedeul de epurare a apelor uzate de la producţiile galvano-chimice de ioni de amoniu include prelucrarea apei cu eluanţi, conţinând ionii de Mg2+ obţinuţi la regenerarea răşinilor schimbătoare de ioni utilizate la dedurizarea apei şi cu soluţiile uzate de la degresare alcalinizată conţinând trisodiufosfat la raportul masic [NH4 +] : [Mg2+] : [PO4 3-] = 1 : (5,2…5,5) : (9,0…9,5) şi pH-ul 8,5…10,0. După care apa se prelucrează prin electrocoagulare cu electrozi solubili de aluminiu la densitatea anodică a curentului de 0,2 … 0,5 A/dm2 şi se separă prin electroflotare complexul compus din magneziu-amoniu-fosfat.
