Abstract
Inventia se refera la un procedeu de epurare a apelor uzate de la productiile galvano-chimice de ioni de amoniu. Procedeul de epurare a apelor uzate de la productiile galvano-chimice de ioni de amoniu include prelucrarea apei cu eluanti, continand ionii de Mg2+ obtinuti la regenerarea rasinilor schimbatoare de ioni utilizate la dedurizarea apei si cu solutiile uzate de la degresare alcalinizata continand trisodiufosfat la raportul masic [NH4+] : [Mg2+] : [PO43-] = 1 : (5,2…5,5) : (9,0…9,5) si pH-ul 8,5…10,0. Dupa care apa se prelucreaza prin electrocoagulare cu electrozi solubili de aluminiu la densitatea anodica a curentului de 0,2 … 0,5 Ŕ/dm2 si se separa prin electroflotare complexul compus din magneziu-amoniu-fosfat.The invention relates to a process for wastewater treatment from galvanic-chemical productions of ammonium ions. The process of wastewater treatment from galvanic-chemical productions of ammonium ions includes water processing with eluents, containing Mg2 + ions obtained at the regeneration of ion exchange resins used for water softening and with the solutions used from alkaline degreasing containing trisodiumphosphate. [NH4 +]: [Mg2 +]: [PO43-] = 1: (5.2 ... 5.5): (9.0 ... 9.5) and pH 8.5 ... 10.0. After that, the water is processed by electrocoagulation with soluble aluminum electrodes at an anodic current density of 0.2 ... 0.5 Ŕ / dm2 and the complex composed of magnesium-ammonium-phosphate is separated by electroflotation.
