Kutheni iPolyaluminium chloride ingayisusa iFluoride?

I-Fluoride yiminerali eyityhefu. Idla ngokufumaneka emanzini okusela. Umgangatho wangoku wamanzi okusela wamazwe ngamazwe wefluoride omiselwe nguMbutho wezeMpilo weHlabathi (i-WHO) yi-1.5 ppm. Amanqanaba aphezulu e-fluoride anokubangela i-fluoride yamazinyo kunye ne-skeletal fluorosis, ngoko ke i-fluoride engaphezulu kufuneka isuswe emanzini okusela. Phakathi ezahlukeneyoiikhemikhali zokunyanga amanziekhoyo, i-polyaluminium chloride (PAC) lukhetho lokuqala lokususwa kwefluoride. Isakhono sokususa i-fluoride sePAC sivela kwiimpawu zayo ezizodwa zeekhemikhali kunye nendlela yokusebenza. Makhe sihlolisise indlela yayo, iingenelo kunye nokusetyenziswa kwayo.

Indlela yokusebenza yepolyaluminium chloride:

Polyaluminium chlorideyi-coagulant ye-inorganic eveliswa yi-reaction ye-aluminium hydroxide kunye ne-hydrochloric acid. Ihlala isetyenziswa njenge-flocculant kwiinkqubo zikamasipala kunye nezoshishino zokucoca amanzi.

I-Polyaluminium chloride i-electrostatically adsorb kwaye idibanise ne-fluoride ion ukwenza iindidi zekhompleksi ezizinzileyo. Oku kuphinda kudale kwaye kugalele i-aluminiyam enganyibilikiyo ifluoride.

I-aluminiyam ion kunye ne-fluoride ion nazo zinokwenza iindidi ezizinzileyo (ezifana , ukunciphisa ukuxinwa kwe-fluoride yamahhala emanzini.

Izinto eziluncedo zePAC njenge defluoridant

Ukusebenza okuphezulu: I-PAC inokufikelela kumazinga abalulekileyo okususa i-fluoride, edla ngokugqitha kuma-90% phantsi kweemeko ezifanelekileyo. Xa kuthelekiswa neetyuwa ze-aluminiyam zesintu, iPAC inoxinano lwentlawulo ephezulu kunye nesantya sokuqukuqela ngokukhawuleza. Ukusebenza kakuhle kwe-defluoridation kunyuswe ngama-30% kwidosi efanayo.

Ezoqoqosho: Iindleko zonyango zincitshiswe ngaphezu kwe-40% xa kuthelekiswa nobuchwepheshe obufana ne-osmosis eguqukayo, kwaye akukho zixhobo ezinzima ezifunekayo.

Kwaye uluhlu lwesicelo se-pH lubanzi (5.0-9.0). Kwaye i-turbidity yamanzi inokuncitshiswa ngaxeshanye.

Ukuveliswa kwe-sludge ephantsi: I-sludge encinci yenziwe, kulula ukuyilawula.

Amanqaku ngePAC njenge defluoridant:

I-PAC iqhuba kakuhle kakhulu kwi-acidic kancinane ukuya kumaxabiso angathathi hlangothi e-pH (malunga ne-6.5 ukuya kwi-7.5). Ukugcina ixabiso elifanelekileyo le-pH kuqinisekisa ukukhutshwa okuphezulu kwe-fluoride.

Ukususwa kwe-fluoride kuxhomekeke kugxininiso lokuqala lwe-fluoride kunye nomthamo we-coagulant.

Ukusetyenziswa kwePAC kwiFluoride Removal

Ukucocwa kwamanzi kamasipala: Qinisekisa ukhuseleko lwamanzi okusela ngokunciphisa i-fluoride ukuya kumanqanaba amkelekileyo.

Ukucocwa kwamanzi amdaka kwimizi-mveliso: Susa i-fluoride kumanzi amdaka aveliswa yimizi-mveliso efana nokwenza iiglasi, imveliso yesemiconductor kunye nezityalo zesichumisi.

Ukubuyiselwa kwezinto eziphilayo: Nyanga amanzi aphantsi komhlaba kunye nomhlaba ongcoliswe yifluoride yendalo ukukhusela indalo esingqongileyo.

Ukubuyiselwa kwezolimo nokusingqongileyo: Susa ii-ion zeFluoride kumanzi okunkcenkceshela ukunqanda ukufakwa kwetyuwa emhlabeni kunye nokonakala kwezityalo.

I-Polyaluminium chloride sisisombululo esiqinisekisiweyo nesisebenzayo sokususwa kwe-fluoride kwizicelo zonyango lwamanzi. Ukukwazi kwayo ukujiya kunye ne-adsorb fluoride ions yenza ukuba ibe yinto yokuqala yokuzikhethela kwiindawo zikamasipala kunye nezoshishino. Kubaluleke kakhulu ukukhetha umthengisi weekhemikhali othembekileyo phakathi kwabaninziUmboneleli wePACs. Kufuneka uqinisekise iziqinisekiso zabo kunye nomgangatho wemveliso. Ukuba ufuna naluphi na uncedo ekuthengeni iPAC, nceda undazise. Sinokubonelela ngeesampuli zamahhala kunye neenkonzo zokukhetha. Ndijonge phambili ukukubona!
