Itandukaniro riri hagati ya sulfate ya polyferric na sulfate ya ferrous

Itandukaniro rikomeye riri hagati ya ferrous sulfate na polymeric ferric sulfate rigaragarira mu miterere ya shimi, ingaruka zo kuvura, uburyo ikoreshwamo n'uburyo ibidukikije bihuzwa n'imiterere yabyo, nk'uko bikurikira:

I. Imiterere n'imiterere y'ibinyabutabire

1. Ireme rya shimi n'imiterere ya valensi ya iyoni y'icyuma

● Sulfate ya Feri: formula y'ikinyabutabire ni FeSO₄·7H₂O, icyuma ni divalent (Fe²⁺), ni ingenzi ku bintu bidafite molekile. Ifite ubushobozi bwo kugabanya kandi ishobora gukorana na chromium hexavalent n'indi myanda ihumanya binyuze muri REDOX reaction.
● Sulfate ya Polyferrike: Formula y'ibinyabutabire ni [Fe₂(OH)ₙ(SO₄)₃-ₙ/₂]ₘ, hamwe n'icyuma kiri mu cyiciro cya gatatu (Fe³⁺), kiba mu ma polymeri y’inorganic. Nyuma yo gushonga, ikora complexes za nuclear nyinshi (nka [Fe₂(OH)₄]²⁺), zikuraho imyanda binyuze mu kuyishyira mu mwanya wayo no kuyigabanya mu buryo bw'amashanyarazi.

2. umutungo ufatika

● Sulfate ya Feri: icyatsi cyoroshye cyangwa umuhondo woroshye nk'ikinyabuzima gikomeye, cyoroshye gutandukanya, umuti ni icyatsi cyoroshye; ugomba kuba uri mu mimerere ya alkaline nke (pH 8-10) kugira ngo ugere ku ngaruka nziza.
● Sulfate ya Polyferrike: ifu/amazi y'umuhondo w'umukara cyangwa umutuku w'umukara, ishonga nke, ariko pH yo kwihuza n'amazi iratandukanye (4-11), cyane cyane ikwiriye ubushyuhe buke n'amazi meza.

II. Amashami y'ikoreshwa n'ingaruka zo gutunganya

1.ferrisulfas

● Imiterere y'imikorere:
● Ifite imiterere yo kugabanya (nk'ukugabanya chromium hexavalent ikaba chromium trivalent), imiterere yo gufungana hamwe n'imiterere yo gukuraho ibara.
     ● Ingaruka zo guhindura ibara zirakomeye, kandi amazi mabi y’irangi rishobora kuba hafi nta ibara nyuma yo kuvurwa.
● Porogaramu nyamukuru:
● Amazi yanduye akoreshwa mu gusiga amashanyarazi (avuwe n'ibyuma biremereye nka chromium na copper).
● Ubuhinzi (inyongeramusaruro y'icyuma), imiti yica udukoko mu nganda.

2.Sulfate ya Polyferrike

● Imiterere y'imikorere:
● Igipimo cyo gukuraho COD na BOD cyari 80% na 93% uko bikurikirana binyuze mu kuyungurura no gufata ibidukikije bya kirimbuzi byinshi.
● Ingaruka zo gukuraho ibara ni nkeya gato ugereranyije n’iza ferrous sulfate (94%-98% ugereranyije n’izitagira ibara), ariko ni nziza cyane mu gukuraho COD.
● Porogaramu nyamukuru:
● Gusukura amazi, Amazi y'imyanda yo mu nganda (gusiga irangi, gukora impapuro, gusiga amashanyarazi, nibindi), gukuraho amazi mu myanda.
● Ubushyuhe buke cyangwa ubushyuhe bwinshi Gutunganya amazi.

Ikiguzi n'ingaruka ku bidukikije

● Sulfate ya feri: ihendutse, ariko yoroshye kuyisiga ikananirwa. Gukoresha cyane bizatuma habaho ioni z'icyuma zisigara mu mazi, ibyo bikaba byatera umwanda w'inyongera.
● Sulfate ya Polyferrike: igipimo ni 20%-50% bya ferrous sulfate gusa, umwanda muke kandi byoroshye kuwukuraho, nta bisigazwa bya aluminiyumu na chlorine, kandi ni byiza kurengera ibidukikije.

Izindi tandukaniro

muri make

Sulfate y'icyuma ikwiriye kuvura imyuka ihumanya ikirere (nk'iy'icyuma gipima hexavalent) n'ibintu bihendutse, mu gihe sulfate y'icyuma ikoresha polymeric ikora neza kandi itangiza ibidukikije, ikwiriye gusukura amazi mu buryo bugoye. Amahitamo nyayo agomba guhuzwa n'ubwoko bw'imyanda ihumanya ikirere, ibisabwa mu kuyitunganya ndetse n'ingengo y'imari ikoreshwa.
