Farqiga u dhexeeya sulfate birta iyo sulfate birta

Farqiga ugu weyn ee u dhexeeya ferrous sulfate iyo polymeric ferric sulfate waxaa lagu muujiyey sifooyinka kiimikada, saameynta daaweynta, xaaladaha codsiga iyo la qabsiga deegaanka, sida soo socota:

I. Sifooyinka kiimikada iyo qaab-dhismeedka

1. Qaacidda kiimikada iyo xaaladda qiimaha birta ee ion

● Ferrous sulfate: Qaacidada kiimikada waa FeSO₄·7H₂O, birtu waa mid u qaybsan (Fe²⁺), waxay ka tirsan tahay iskudhisyo aan molecular ahayn oo hooseeya. Waxay leedahay sifooyin yareynaya waxayna la falgeli kartaa hexavalent chromium iyo wasakheeyayaasha kale iyadoo la adeegsanayo falcelinta REDOX.
● Polyferric sulfate: Qaacidada kiimikada waa [Fe₂(OH)ₙ(SO₄)₃-ₙ/₂]ₘ, iyadoo birtu ku jirto xaaladda saddex-geesoodka ah (Fe³⁺), waxay ka tirsan tahay polymers aan organic ahayn. Ka dib marka la isku shubo, waxay samaysaa isku-dhafan badan oo nukliyeer ah (sida [Fe₂(OH)₄]²⁺), kuwaas oo ka saara wasakhowga iyada oo loo marayo nuugista iyo dhexdhexaadinta elektarooniga.

2. hantida jireed

● Ferrous sulfate: cagaar khafiif ah ama huruud khafiif ah oo crystalline ah, si fudud loo deli karo, xalku waa cagaar khafiif ah; waa inuu ku jiraa xaalado alkaline yar (pH 8-10) si loo gaaro saameynta ugu fiican.
● Polyferric sulfate: budo/dareere bunni huruud ah ama casaan ah, milmi yar, laakiin pH kala duwan oo la qabsi ah (4-11), gaar ahaan ku habboon heerkulka hooseeya, tayada biyaha oo wasakh badan leh.

II. Meelaha codsiga iyo saameynta habaynta

1.ferrisulfas

● Sifooyinka shaqada:
● Waxay leedahay sifooyin yareeya labadaba (sida yareynta chromium hexavalent ilaa chromium trivalent), sifooyinka xinjirowga iyo sifooyinka kala-baxa midabka.
     ● Saamaynta midab-beddelku waa mid xooggan, biyaha wasakhda ah ee rinjiga fal-celinta leh waxay noqon karaan kuwo aan midab lahayn ka dib daaweynta.
● codsiga ugu muhiimsan:
● Biyaha wasakhda ah ee Elektroplating (waxaa lagu daaweeyaa biraha culus sida chromium iyo copper).
● Beeraha (birta dheeraadka ah), sunta cayayaanka warshadaha.

2.Polyferric sulfate

● Sifooyinka shaqada:
● Heerka ka saarista COD iyo BOD wuxuu ahaa 80% iyo 93% siday u kala horreeyaan iyadoo la nuugayo oo la qabsanayo isku-dhafka nukliyeerka badan.
● Saamaynta midab-beddelku waa mid xoogaa ka daciifsan tan birta sulfate (94%-98% marka loo eego ku dhawaad ​​​​midab la'aan), laakiin way ka waxtar badan tahay ka saarista COD.
● codsiga ugu muhiimsan:
● Nadiifinta biyaha, Qashinka Warshadaha (rinjiyeynta, sameynta warqadaha, sameynta elektrolajiyada, iwm.), nadiifinta wasakhda.
● Heerkul hoose ama wasakh badan Daaweynta Biyaha.

Saamaynta kharashka iyo deegaanka

● Ferrous sulfate: kharash yar, laakiin si fudud ayaa loo oksaydhi karaa oo loo fashilmi karaa. Isticmaalka xad-dhaafka ah wuxuu keeni doonaa aayoonnada birta ee ku haray biyaha, taasoo keeni karta wasakhowga labaad.
● Polyferric sulfate: qiyaasta waa 20%-50% oo keliya oo ah sulfate ferrous ah, wasakh yar oo si fudud loo fuuq-celiyo, haraaga aluminium iyo chlorine ma jiro, ilaalin deegaan oo wanaagsan.

soo koobid

Ferrous sulfate wuxuu ku habboon yahay daaweynta yaraynta wasakhowga (sida chromium hexavalent) iyo xaaladaha qiimaha jaban, halka polymeric ferric sulfate uu yahay mid waxtar badan leh oo deegaanka u fiican, kuna habboon nadiifinta biyaha ee adag. Doorashada dhabta ah waa in lagu daraa nooca wasakhowga, shuruudaha daaweynta iyo miisaaniyadda kharashka.
