Coagulants - Iyini? Ngabe waya kuphi futhi coagulants esetshenziswa

Ukusetshenziswa kwamanzi ahlanzekile kuthuthukisa impilo kanye womuntu amasosha omzimba, ngaphandle uyalulama umzimba ngokwawo, usebenzisa izinqolobane zalo siqu. Abantu amakhulu eminyaka wahlala eduze imifula kanye namachibi, usebenzisa labo imithombo ukuthi wanikela ngokuphila nemvelo. IMIPHAKATHI abaningi basendulo kakade wayazi ukuthi okuhlanza amanzi ngoba izidingo zezakhamizi by odlula khona ngokusebenzisa izingqimba ngobumba isihlabathi. Ngalezo zinsuku, abantu abaningana abazange bayisebenzise coagulants (yalolu ketshezi, okuyinto kuveza ukwelashwa eyinhloko amanzi anikeza ukuphila namuhla).

amanzi ahlanzekile ezahlukene okunjalo

Ezweni lanamuhla kubhekwa ukuthi, kuhle, abantu kumele basebenzise emizini yabo Zintathu izinhlobo amanzi:

• amanzi kampompi ukuthi isidlulile ejwayelekile amaningi yokuhlanza indawo kanye ukusefa e izifiki ekhethekile;
• yasendlini, ngaphambili sashintsha ukuvimbela isikali kwetinhlavu Ukushisa zikagesi ezisetshenziswa okugeza nokugeza;
• ukuphuza, isetshenziswa kuphela kokungenisa nokupheka.

amanzi Plain efulethini inikeza ezisemadolobheni amanzi supply system. Self-ekhaya post-ukwelashwa usebenzisa ehlunga ahlukahlukene, ngokwakhiwa kohlelo neyaziwayo iwusizo ezinye amaminerali (ezifana shungite). Ngaphezu kwalokho, kukhona coagulants, magciwane zamanzi ukusetshenziswa ekhaya.

Kwenzekani amanzi ngaphambi kokungena ipayipi

Ngaphambi kobana azinze futhi filtration kukhicite ukwelashwa kwangaphambilini olunzima amanzi senzelwe nezelani ezisemadolobheni amanzi ompompi. Okokuqala, izigubhu ezikhethekile ngokushesha ukuxuba amanzi coagulant (kukhona amakhemikhali ezikhethekile). Lapho coagulating umuzwa wokwenyanya electrostatic izinhlayiya ziyoncibilika emanzini kuyehla, bona banamathelane. Lokhu kusiza futhi isheshisa yokuhlanza ngesikhathi sokulungisa kanye filtration.

Inqubo ukugcwalisa ithange eyodwa kumele kutsatse ngomunye ngomzuzu. Nge isikhathi ezincane isikhawu ayinikeze ukufana edingekayo yokuhlanganisa ketshezi ngamanzi. Ngezinye ukuxhumana eside zingase zephule floccules kwakhiwa (kwenze slipshiesja izinhlayiya angaphandle). Ngemva edabula amathangi eziningana lapho coagulants ngoba amanzi axutshwe ngayo izinga kancane kancane kuyancipha, uketshezi ngaphansi sedimentation.

Yini Yigama elihle "flocculation"

Coagulants - kukhona reagents zamakhemikhali. Akubona bonke ziyingozi izinto zabantu zingase etholakala e filtration evamile phakathi nesikhathi esifushane. Ezinye zazo yilezi esimweni siphela. Uma ukungcola abakhona emanzini noma hydrosols, le coagulants ukuze bayothola ukwelashwa amanzi ngesikhathi ukuxhumana nabo ukwakha kwenze zingaxazululeki ngesimo slurry. Inqubo kumiswa izinhlayiya emihle agglomerated, i- "izinqwaba" zinkulu futhi ngokuthi flocculation. Usayizi izinhlayiya entsha lingafika amamilimitha angu eziningana.

Yiqiniso, ungakwazi ukuhlanza amanzi kusukela ukungcola ahlukahlukene filtration evamile, kodwa ngeke kuthathe iminyaka eminingana, futhi empeleni akudingeki ukudicilela nsuku omningi. Ekuhlungeni bokushesha okwanele labathaki bamafutha kunezelwa coagulants. Lokhu kunciphisa ukukhululwa ezingadingekile wamanzi kusukela kuzo zonke izinto eziyingozi ukuze imizuzu 30-45. Nge izakhamizi okusheshayo emadolobheni nasemadolobhaneni bayakwazi komzamo zisebenzisa amanzi zisemakhaya azo.

Kwenzekani ngesikhathi isitshalo indle

Ngo amanzi, ngisho okusobala shazi, ngokuvamile iqukethe semali amanyela. Phakathi kwabo kukhona izinto ezilandelayo:

• Gypsum kanye wokulinganisa;
• isihlabathi nobumba emadwaleni;
• yl ne-plankton;
• kancane oncibilikayo metal hydroxides;
• amagciwane;
• amakhemikhali ziyoncibilika;
• ukumiswa ahlukahlukene.

izinhlayiya Heavy nezinkulu ngongqimba ethize okusezingeni eliphezulu angabacwasi ngokushesha kuwele phansi nesifiki imizuzu 1-2. Kunonophisa inqubo sedimentation (kwenze kumiswa) izinhlayiya emihle, engahlala isikhathi esingaba iminyaka emibili, amanzi ingezwe coagulants. Lokhu chloride ferric, alumina sulphate, yensimbi sulfate, gidroksosulfaty hydroxychloride kanye ne-aluminium, nensimbi exutshwe ne-aluminiyamu nosawoti, opacifiers ubumba, ezahlukene flocculating ukumiswa kanye brighteners.

Zokuhlanzwa futhi ukucaciseleka yamanzi simiso sokulungisa mpo ku 1 ilitha 50 kuya ku-100 ml reagent. Lakhulisiwe futhi ethe njo ndawonye ngenxa yesenzo amakhemikhali izinhlayiya colloidal ziyazika elibuye ahlukaniswe kalula iwukuxazulula futhi filtration.
