Abstract
Au fost studiaţi parametrii tehnologici ai procesului galvanocoagular de tratare a apelor uzate ce conţin ioni de Cr(VI)
şi coloranţi organici, care decurge datorită electrolizei interne. Sunt discutate particularităţile proceselor de dizolvare
anodică a fierului din contul diferenţei de potenţiale ale elementelor ce formează perechile galvanice, precum şi transformările
de coagulare, sorbţie, distrugere, oxidoreducere şi cele fazo-disperse. Aceste transformări asigură formarea
structurii cristaline a sedimentelor de tip spinel cu proprietăţi fieromagnetice, care pot fi utilizate în mod diferit. Sunt
marcate avantajele acestor procese de tratare a apelor uzate tehnogene, care pot fi realizate într-o singură instalaţie.
The technological parameters of galvano-coagulation tr eatment of waste water, containing Cr(VI) and organic colorants, which occur due to the internal electrolysis, are studied. The specifics of iron anodic dissolving, taking place due to the difference of the potentials of galvanic pairs' elements is discussed, as well as the coagulation, sorption, destructive reduction-oxidation processes. These transformations ensure the formation of spinel crystalline sediments with the ferromagnetic properties, which can be utilized in several ways. The advantages of these treatment processes, which can be realized in one and the same reactor, are highlighted
