1. Boma la Municipal Kuchiza Madzi

Kumwa Kuyeretsa Madzi

Kuchotsa algae m'madzi osaphika komanso osakhala ndi matope: imatha kuchotsa bwino zinthu zolimba, algae ndi zinthu zodetsedwa m'madzi osaphika. Imasungabe mphamvu yabwino yodumphira m'malo otentha kwambiri (osakwana 5℃), omwe ndi oyenera kutsukidwa ndi madzi m'nyengo yozizira.

Kuchotsa zitsulo zolemera: kumakhala ndi mphamvu yothira madziPacKuteteza zitsulo zolemera monga arsenic (As) ndi lead (Pb), kuonetsetsa kuti madzi otuluka m'madzi akumwa akukwaniritsa miyezo ya ukhondo.

Kugwiritsa ntchito mu chomera choyeretsera zinyalala

Kuchotsa madzi m'matope: kufulumizitsa kukhazikika kwa matope m'thanki yoyamba ya sedimentation/thanki yachiwiri ya sedimentation, kuchepetsa zinthu zolimba zomwe zimapachikidwa (SS) ndi kufunika kwa okosijeni wa mankhwala (COD), ndikuchepetsa katundu wothandizidwa pambuyo pake.

Zimbudzi zapakhomo za m'mizinda: Pokonza zimbudzi zapakhomo zomwe zimakhala ndi matope ambiri, floc imapangidwa mwachangu komanso mopyapyala, ndipo liwiro lokhazikika limaposa 30% kuposa la ma coagulants achikhalidwe (monga PAC).

2. Kukonza madzi otayira m'mafakitale

Kupaka/kupaka utoto madzi otayira

Kuchotsa utoto ndi kuwonongeka: kuchotsa bwino utoto wa utoto (monga utoto wochita kusintha, utoto wa asidi) ndi lignin, kuchuluka kwa chromaticity kuchotsa ndi kopitilira 85%, ndikuwonjezera kuwonongeka kwa madzi otayidwa.

Kuchepetsa COD: Pa madzi otayira achilengedwe okhala ndi kuchuluka kwakukulu, mlingo umachepetsedwa ndi 20% poyerekeza ndi aluminiyamu sulfate, zomwe zimachepetsa mtengo wochizira.

Kulekanitsa mafuta: kudzera mu mphamvu ya kuletsa kuwononga mafuta kuti aswe msanga emulsion, kuyamwa kwa zinthu zoipitsa mafuta, zoyenera kugwiritsa ntchito mafuta, kupangira madzi otayira.

Kuyeretsa madzi m'migodi: kuchotsa chitsulo (Fe²⁺), manganese (Mn²⁺), sulfide ndi mchere wina nthawi imodzi, kuthetsa vuto la kutayikira ndi zitsulo zolemera m'madzi am'migodi.

Madzi otayira chakudya/mankhwala

3. Kubwezeretsa chilengedwe ndi kasamalidwe ka zachilengedwe

Mankhwala amadzi akuda komanso onunkha

Kuwongolera mawonekedwe a algae: Kugwa mwachangu kwa algae ndi zinthu zachilengedwe zomwe zimapachikidwa, kukonza bwino mawonekedwe a mitsinje, kuletsa kufalikira kwa algae.

Kuyeretsa dziwe la madzi amvula

Kusamalira madzi opanda mafunde ambiri: kumakhala kosavuta kugwiritsa ntchito madzi opanda mafunde ambiri omwe ali mu dongosolo losonkhanitsira madzi amvula, ndipo mphamvu ya flocculation imakhala yokhazikika.

4. Malangizo ogwiritsira ntchito ndi malingaliro osinthira mawonekedwe

Makhalidwe a malo	Kupambana kwa PAFC	nkhani zimafunika chisamaliro
Madzi oundana otentha pang'ono (	Kuchuluka kwa hydrolysis kumachitika mwachangu ndipo ma flocs ndi okhuthala	Palibe zida zina zowonjezera zotenthetsera zomwe zimafunika
Madzi otayira okhala ndi chromaticity yambiri (kusindikiza ndi kupaka utoto)	Chigawo cha mchere wachitsulo chimathandiza kuti mtundu usinthe.	Sinthani pH 5-10 kuti mupewe mvula ya ayoni yachitsulo
Madzi otayira mafuta ambiri	Zotsatira za kuswa mkaka zimakhala zabwino ndipo madzi amatuluka mwachangu	Iyenera kuphatikizidwa ndi njira yoyandama mpweya kuti ilimbikitse kulekanitsa mafuta
Madzi a m'migodi olimba kwambiri	Ma ayoni achitsulo angapo amachotsedwa nthawi imodzi	Yang'anani kuchuluka kwa aluminiyamu/chitsulo chotsala nthawi zonse

Malo ofunikira kwambiri ogwiritsira ntchito polyaluminium ferric chloride ndi monga kuyeretsa madzi (kupereka madzi m'maboma), kuchepetsa kutulutsa kwa mpweya m'mafakitale (kupanga mapepala, kupukuta utoto, ndi migodi), komanso kubwezeretsa chilengedwe (kuchiza madzi akuda ndi onunkhira). Kugwiritsa ntchito kwake bwino kutentha kochepa komanso magwiridwe antchito ambiri kumapangitsa kuti ikhale njira yabwino kwambiri m'malo mwa ma coagulants achikhalidwe. Mapulani enieni a mlingo ayenera kutsimikiziridwa kudzera mu mayeso oyeserera kuti apewe kumwa kwambiri, zomwe zingayambitse kukhazikikanso kwa ma colloids.
