Ngabe i-polyaluminium chloride isusa kanjani ukungcola emanzini?

Polyaluminium chloride, kuvame ukufushaniswa njenge-PAC, uhlobo lwe-inorganic polymer coagulant. Kuboniswa ngobuningi balo obukhulu bezinkomba kanye nesakhiwo se-polymeric, okwenza kube kuhle kakhulu ekungcolisweni nasekutholeleni ukungcoliswa kwamanzi emanzini. Ngokungafani nama-coagulants endabuko afana ne-alum, i-PAC isebenza ngempumelelo kulo lonke uhla lwe-PH ebanzi futhi ikhiqiza imikhiqizo embalwa ye-sludge, okwenza kube yindawo enobungani bemvelo.

Indlela yokwenza isenzo

Umsebenzi oyinhloko we-PAC ekwelashweni kwamanzi ukuhlehlisa futhi uhlanganise izinhlayiya ezimisiwe ezimisiwe, ama-colloids, kanye nendaba ye-organic. Le nqubo, eyaziwa ngokuthi ukuhlangana nokuhlangana, ingadilizwa ibe yizigaba eziningana:

1. Lokhu kungathathi hlangothi kunciphisa amandla aphezulu phakathi kwezinhlayiya, okubavumela ukuba zisondele ndawonye.

2. I-Floccution: Ukulandela ukugeleza, izinhlayiya ezingathathi hlangothi zihlangana ukuze zakhe ama-flocs amakhulu. Imvelo ye-polymeric ye-PAC AIDS ekuvinjelweni kwezinhlayiya, ukudala ama-flocs amakhulu angasuswa kalula.

I-3. Ukudonswa kwe-sediment kanye ne-filtration: Ama-flocs amakhulu akhiwa ngesikhathi sokuhlanzeka kwe-floccution ngokushesha ngenxa yamandla adonsela phansi. Le nqubo yedimentation isusa ngempumelelo ingxenye ebalulekile yokungcola. Ama-flocs asele angasuswa ngokuhlunga, okuholela emanzini acwebile futhi ahlanzekile.

Izinzuzo ze-PAC

IsinyatheloInikeza izinzuzo eziningana ngaphezu kwendabuko yama-coagulants, ifaka isandla ekudumeni kwayo okukhulayo ekwelashweni kwamanzi:

- Ukusebenza kahle: I-PAC isebenza kakhulu ekususeni okuhlukahlukene kwezingcola, kufaka phakathi ama-solids amisiwe, udaba lwe-organic, ngisho nezinye izinsimbi ezisindayo. Ukusebenza kwayo kunciphisa isidingo samakhemikhali angeziwe nezinqubo.

- Ibanga elibanzi le-PH: ngokungafani namanye ama-coabulants adinga ukulawulwa kwe-PH okuqondile, i-PAC isebenza kahle ngaphesheya kwe-PH Spectrum, yenza lula inqubo yokwelashwa.

- Okuncishisiwe ukukhiqizwa kwe-sludge: Enye yezinzuzo ezibalulekile ze-PAC yivolumu encishisiwe ye-sludge eyenziwe ngesikhathi sokwelashwa. Lokhu kunciphisa izindleko zokulahla futhi kunciphisa umthelela wezemvelo.

- Ukusebenza kwezindleko: Ngenkathi i-PAC ingahle ibe nezindleko eziphezulu eziphezulu ngokuqhathaniswa namanye ama-coagulants endabuko, ukusebenza kwayo okuphakeme kanye nezidingo zemithamo ephansi zivame ukubangela ukonga izindleko zonke zezindawo zokwelashwa kwamanzi.

Ama-PAC Flocculants imele intuthuko ebalulekile kubuchwepheshe bokwelashwa kwamanzi. Ikhono layo lokususa ngempumelelo ama-contaminants, lihlanganiswe nezinzuzo zemvelo nakwezomnotho, izikhundla ze-PAC njengetshe legumbi ekufuneni kwamanzi ahlanzekile neliphephile. Njengoba imiphakathi eminingi kanye nezimboni zamukela lesi sixazululo esisha, indlela eya ngekusasa elinempilo nelinzile liyacaca.
