Kodi polyaluminum chloride ingagwiritsidwe ntchito ngati dothi la mafuta?

Polyaluminum chloride (PAC) ingagwiritsidwe ntchito ngati chothandizira kutayira mafuta, makamaka pochiza zinyalala zamafuta.

I. Mfundo Zoyambira

Q1: N’chifukwa chiyani polyaluminum chloride imatha kuchiza madzi otayira amafuta?

A: PAC imapanga ma multinuclear complexes kudzera mu hydrolysis ndipo imagwira ntchito zitatu:

●Kuchepetsa mphamvu zamagetsi: kuwononga mphamvu ya pamwamba ya madontho a mafuta ndikulimbikitsa mafuta osungunuka kuti asweke ndikugwa;

●Kuthira madzi m'nthaka: kumamatira tinthu ta mafuta omwazikana kukhala tinthu tating'onoting'ono kuti tifulumizitse kusungunuka kwa madzi;

●Mvula ya m'madzi: kuchotsa pamodzi zitsulo zolemera, zinthu zachilengedwe ndi zinthu zina zoipitsa.

Q2: Ndi mafuta amtundu wanji omwe PAC imachotsa bwino?

A: Imagwira ntchito bwino kwambiri pa mafuta osungunuka ndi tinthu ta mafuta a colloidal (chiwerengero chochotsera> 80%), koma iyenera kuphatikizidwa ndi chithandizo choyambirira cha mafuta kuti mafuta oyandama akhale ambiri (monga mafuta osakonzedwa).

II. Kugwiritsa ntchito moyenera

Q3: Kodi mungawonjezere bwanji PAC molondola?

A: Iyenera kuchitika pang'onopang'ono:

1. Kusungunuka: PAC yolimba imasakanizidwa ndi madzi mu chiŵerengero cha 1:3 kuti ipange mowa woyambirira;

2. Kusakaniza: Mowa wothira umachepetsedwa nthawi 10-30 (mlingo woyenera ndi 10-20%);

3. Ndalama:

●Kukhuthala kwa madzi otayira 100-500mg/L: 5-20kg/ matani chikwi a madzi;

●Madzi otayira okhala ndi mafuta ambiri: mlingo wake uyenera kutsimikiziridwa ndi mayeso oyendetsa.

Q4: N’chifukwa chiyani muyenera kusakaniza ndi PAM? Kodi mungagwiritse ntchito bwanji?

A:

●Chifukwa: Mphamvu ya floc siikwanira pamene PAC ikugwiritsidwa ntchito yokha, ndipo cationic PAM ikhoza kuwonjezera kukhuthala kwa floc;

●Gawo: PAC imawonjezedwa kaye kuti iswe emulsion, kenako yankho la 0.1%-0.5% la PAM la cationic limawonjezedwa kuti lithandize kutsekeka kwa magazi.

Q5: Kodi mungayang'anire bwanji magawo a chilengedwe?

A:

●PH Scope: Mtundu wabwino kwambiri ndi 5.0-9.0, ndipo asidi/alkali wambiri amachepetsa mphamvu yoletsa mphamvu ya magetsi;

●Kutentha: Kutentha kukatsika kuposa 10℃, kumayamba kuchepa, choncho ndikofunikira kuwonjezera mlingo kapena kusunga kutentha.

III. Zochitika ndi milandu yamakampani

Q6: Ndi mafakitale ati omwe ali oyenera kuti PAC ichite ntchito yoyeretsa madzi otayira amafuta?

A: Zochitika zomwe zimachitika nthawi zambiri zimaphatikizapo:

●Petrochemical: kuchotsa mafuta m'madzi ozungulira fakitale yoyeretsera kuti muchepetse COD;

●Kukonza chakudya: kuchuluka kwa mafuta omwe amachotsedwa m'madzi otayira ophera **>80%**;

●Kupanga makina: kudula madzi, kutulutsa madzi mu emulsion;

●Kusindikiza ndi kupaka utoto nsalu: kuchotsa utoto ndi mafuta mogwirizana.

Q7: Kodi mungatsimikizire bwanji zotsatira zenizeni?

A: Nkhaniyi ikusonyeza kuti:

●Mafakitale oyeretsera: kuchuluka kwa mafuta kunachepa kuchoka pa 200mg/L kufika pa 15mg/L atagwiritsa ntchito PAC ndi PAM pamodzi;

●Fakitale ya batri: kuyika kwa zitsulo zolemera ndi fluoride mogwirizana.

IV. Mafunso Ofunsidwa Kawirikawiri

Q8: Kodi ndi zifukwa ziti zomwe zingachititse kuti PAC isagwire ntchito bwino?

A: Malo akuluakulu owopsa:

●Mafuta oyandama osakonzedwa kale: mafuta oyandama ambiri ayenera kukonzedwa ndi kuyandama kwa mpweya/kulekanitsa mafuta kaye;

●Kutentha kochepa popanda kusintha: pansi pa 5℃, palibe mlingo wowonjezera wa 20% womwe umawonjezeredwa, zomwe zimapangitsa kuti flocculation ichedwe 1;

●Cholakwika posankha PAM: madzi otayira okhala ndi mafuta ambiri ayenera kusankha PAM yolemera pang'ono komanso yapakatikati.

Malangizo a tchati cha kayendetsedwe ka ntchito:

Madzi otayira okhala ndi mafuta → cholekanitsa mafuta (chochotsa mafuta oyandama) → thanki yowongolera (PAC kuti iswe ma emulsions) → thanki yothira madzi (PAM kuti ithandize kutsekeka) → thanki yothira madzi → kutulutsa madzi molingana ndi muyezo

Sinthani malinga ndi khalidwe lenileni la madzi.
