Ingaba iPolyaluminium chloride ilususa njani ungcoliseko emanzini?

I-Polyaluminium chloride, edla ngokufinyezwa njenge-PAC, luhlobo lwe-inorganic polymer coagulant. Ibonakala ngokuxinwa kwayo okuphezulu kunye nesakhiwo sepolymeric, esenza ukuba isebenze ngokugqwesileyo kwi-coagulating kunye ne-flocculating contaminants emanzini. Ngokungafaniyo nee-coagulants zemveli ezifana ne-alum, i-PAC isebenza ngokufanelekileyo kuluhlu olubanzi lwe-pH kwaye ivelisa iimveliso zodaka ezimbalwa, iyenza ibeyenye indlela yokusingqongileyo.

Indlela yokwenza

Owona msebenzi uphambili wePAC kunyango lwamanzi kukuphelisa uzinzo kunye nokuhlanganisa amasuntswana axhonyiweyo, iicolloids, kunye nezinto eziphilayo. Le nkqubo, eyaziwa ngokuba yi-coagulation kunye ne-flocculation, inokwahlulwa ibe ngamanqanaba amaninzi:

1. Ukujiya: Xa iPAC yongezwa emanzini, iiyoni zayo zepolyaluminiyam ezitshajiswe kakhulu zinciphisa iintlawulo ezimbi kumphezulu wamasuntswana amisiweyo. Oku kungathathi hlangothi kunciphisa amandla aphikisayo phakathi kwamaqhekeza, okubavumela ukuba basondele kunye.

2. I-Flocculation: Ukulandela i-coagulation, i-particle neutralized aggregate ukwenza iiflocs ezinkulu. Ubume be-polymeric be-PAC bunceda ekuvaleni amasuntswana, ukudala iiflocs ezinokususwa ngokulula.

3. Intlenga kunye nokuhluzwa: Iiflokhi ezinkulu ezenziwe ngexesha lokuhluma zihlala ngokukhawuleza ngenxa yomxhuzulane. Le nkqubo ye-sedimentation isusa ngokufanelekileyo inxalenye ebalulekileyo yezinto ezingcolileyo. Iiflocs eziseleyo zingasuswa ngokucoca, okubangela amanzi acacileyo nacocekileyo.

Izinto ezilungileyo zePAC

PACinika iingenelo ezininzi ngaphezulu kwe-coagulants yemveli, inegalelo ekukhuleni kwayo ekuthandeni kunyango lwamanzi:

- Ucikizeko: I-PAC isebenza kakhulu ekususeni uluhlu olubanzi lwezinto ezingcolisayo, kubandakanywa izinto eziqinileyo ezinqunyanyisiweyo, izinto eziphilayo, kunye nezinye iintsimbi ezinzima. Ukusebenza kwayo kunciphisa imfuno yeekhemikhali ezongezelelweyo kunye neenkqubo.

- Uluhlu olubanzi lwe-pH: Ngokungafaniyo nezinye ii-coagulants ezifuna ulawulo lwe-pH oluchanekileyo, i-PAC isebenza ngokufanelekileyo kwi-pH spectrum ebanzi, yenza lula inkqubo yonyango.

- UkuNcitshiswa kweMveliso yeSludge: Enye yeenzuzo ezibalulekileyo zePAC kukuncitshiswa komthamo wodaka oluveliswe ngexesha lonyango. Oku kuncitshiswa kwehlisa iindleko zokulahla kwaye kunciphisa impembelelo yokusingqongileyo.

- Ukusebenza kweendleko: Ngelixa iPAC inokuba neendleko eziphezulu zangaphambili xa kuthelekiswa nezinye iicoagulants zemveli, ukusebenza kwayo okuphezulu kunye neemfuno ezisezantsi zedosi zihlala zikhokelela kukongiwa kweendleko zizonke zoncedo lokucocwa kwamanzi.

PAC Flocculants imele ukuqhubela phambili okubonakalayo kubuchwepheshe bokucoca amanzi. Isakhono sayo sokususa ungcoliseko ngokufanelekileyo, sikhatshwa ziinzuzo zokusingqongileyo kunye nezoqoqosho, sibeka iPAC njengelitye lembombo kwiphulo lokufuna amanzi acocekileyo nakhuselekileyo. Njengoko uluntu oluninzi kunye namashishini esamkela esi sisombululo sintsha, indlela eya kwikamva elinempilo nelizinzileyo iya icaca ngakumbi.
