Kaarboon Steel Fenton Reactor ee Daawaynta Biyaha Waste Sawirka
  • Kaarboon Steel Fenton Reactor ee Daaweynta Biyaha Waste

Sharaxaad Gaaban:

Fenton reactor, oo sidoo kale loo yaqaan Fenton dareeraha sariirta dareeraha ah iyo munaaradda falcelinta Fenton, waa qalab lagama maarmaan u ah oksaydhka sare ee biyaha wasakhda ah falcelinta Fenton.Iyada oo ku saleysan munaaradda falcelinta Fenton ee dhaqameed, shirkadeena waxay soo saartay shatiga Fenton dareeraha sariirta.Qalabkani wuxuu isticmaalaa habka sariiraha dareeraha ah si uu u sameeyo inta badan Fe3 + oo ay soo saartay Habka Fenton ee ku xiran dusha sare ee sariirta dareeraha ah ee Fenton side by crystallization ama roobab, taas oo si weyn u yareyn karta qiyaasta Habka Fenton ee dhaqameed iyo qadarka dhoobada kiimikada ee la soo saaray. (ku-darka H2O2 waxa la dhimay 10% ~ 20%).

Habka Mabda'a

Habka oxidation Fenton waa in la abuuro hydroxyl radical (· oh) leh awood oksaydhyo xoog leh joogitaanka Fe2 + xaaladaha acidic, iyo kicin noocyo kale oo ogsijiin kale oo dheeraad ah si ay u ogaadaan xaalufka xeryahooda organic.Habka oksaydhisku waa falcelinta silsiladda.Jiilka · Oh waa bilawga silsiladda, halka noocyada kale ee ogsijiinta falcelinta iyo dhexdhexaadinta falcelinta ay ka kooban yihiin qanjidhada silsiladda.Nooc kasta oo oksijiin fal-celin ah ayaa la cunaa oo silsiladda falcelinta waa la joojiyaa.Habka falcelinta waa mid adag.Noocyadan oksijiinta fal-celiska ah waxa kaliya oo loo isticmaalaa molecules organic waxayna macdan ka dhigtaan walxaha aan noolaha ahayn sida CO2 iyo H2O.Markaa, Fenton oxidation waxay noqotay mid ka mid ah tignoolajiyada oksaydhka horumarsan ee muhiimka ah.

Astaamaha

Fenton reactor, oo sidoo kale loo yaqaan Fenton dareeraha sariirta dareeraha ah iyo munaaradda falcelinta Fenton, waa qalab lagama maarmaan u ah oksaydhka sare ee biyaha wasakhda ah falcelinta Fenton.Iyada oo ku saleysan munaaradda falcelinta Fenton ee dhaqameed, shirkadeena waxay soo saartay shatiga Fenton dareeraha sariirta.Qalabkani wuxuu isticmaalaa habka sariiraha dareeraha ah si uu u sameeyo inta badan Fe3 + oo ay soo saartay Habka Fenton ee ku xiran dusha sare ee sariirta dareeraha ah ee Fenton side by crystallization ama roobab, taas oo si weyn u yareyn karta qiyaasta Habka Fenton ee dhaqameed iyo qadarka dhoobada kiimikada ee la soo saaray. (ku-darka H2O2 waxa la dhimay 10% ~ 20%), Qadarka Fe2 + waxa la dhimay 50% ~ 70%, cadadka dhoobada waxa la dhimay 40% ~ 50%).Isla mar ahaantaana, oksaydhka birta ee ka sameysan dusha sare ee sidaha ayaa leh saameyn catalytic oo kala duwan.Tiknoolajiyada sariirta dareeraha ah waxay sidoo kale kor u qaadaa heerka falcelinta oksaydhka kiimikada iyo saamaynta wareejinta tirada badan, waxay si wax ku ool ah u wanaajisaa heerka COD saarista 10% ~ 20%, waxayna badbaadisaa 30% ~ 50% kharashka daaweynta iyo hawlgalka.

Codsiga

Fenton reactor waxaa si weyn loogu isticmaalaa soo saarista wasakhaha organic refractory, sida daabacaadda iyo dheehidda biyaha wasakhda ah, biyaha wasakhda ah saliidda, phenol wasakh ah, coking biyaha wasakhda, nitrobenzene wasakh ah, diphenylamine wasakh ah iyo wixii la mid ah.Sida tignoolajiyada daaweynta biyaha wasakhda ah ee horumarsan, habka Fenton wuxuu isticmaalaa falcelinta silsiladda u dhaxaysa Fe2 + iyo H2O2 si ay u kiciso jiilka hydroxyl radical (· oh) oo leh oksaydhyo xoog leh, kaas oo oxidize kara noocyo kala duwan oo sun ah iyo xeryahooda organic refractory.Daawaynta biyaha wasakhda ah ee soo celinaysa feejignaanta sare, waxaa loo isticmaali karaa pretreat bayooloji si loo hagaajiyo tayada biyaha loona wanaajiyo biodegradability ee biyaha wasakhda ah, Abuuri xaalado wanaagsan oo daaweyn heersare ah oo xiga.Waxay si gaar ah ugu habboon tahay daaweynta sare ee biyaha wasakhda ah ee ay adag tahay in la baabiiyo ama oksaydheynta kiimikada guud, sida dheecaanka qashinka.
