Kodi ndi madzi otani omwe ali oyenera kugwiritsa ntchito ma coagulants okhala ndi mchere wambiri?

Chotsukira cha mchere wambiri (monga Polyferric Sulfate ndi mchere wa 12% kapena kuposerapo) ndi yoyenera kwambiri pazochitika zapadera izi za khalidwe la madzi chifukwa cha kapangidwe kake kautali wa mamolekyulu, mphamvu yamphamvu yoletsa ma electro-neutralization komanso liwiro la kusefukira kwa madzi mwachangu:

🧪 1. Madzi otayirira ambiri/madzi otayirira ambiri

Kupaka utoto wa madzi otayira

Chokoka cha mchere wambiri (mchere 12%-16%) chimatha kunyamula tinthu ta utoto wa colloidal bwino, kupanga ma floc okhuthala mwachangu, ndikuchotsa utoto ndikuchepetsa COD kwambiri.

Ubwino: mlingo umachepetsedwa ndi 10%-20%, ndipo liwiro lokhazikika limawonjezeka ndi kupitirira 30%, makamaka yoyenera zinyalala.Kampani ya Madziokhala ndi utoto wosinthika kapena utoto wofalikira.

Madzi otayira a fakitole ya mapepala/mapepala

Imakhala ndi mphamvu yaikulu yolumikizira zinthu zomwe zimapachikidwa kwambiri (monga ulusi wa pulp ndi zinyalala za chikopa) ndipo imapewa kumasuka kwa ma flocs.

Dziwani: Njira yobwezeretsa madzi oyera ndi yoletsedwa (kuchotsa ulusi wochuluka m'madzi oundana kumasokoneza mosavuta kubwezeretsa ulusi), ndipo imagwiranso ntchito ku zigawo zina.

❄ 2. Kutentha kochepa komanso madzi abwino okhala ndi matope ochepa

Madzi a m'madzi osungira madzi m'nyengo yozizira

Mu malo otentha pang'ono (

Mlandu: Pochiza madzi osaphika okhala ndi algae otsika kutentha, kuchuluka kwa algaecide kumaposa 90%, ndipo kuchuluka kwa kutayira kwa matope kumawonjezeka ndi 25%.

⚠ III. Zitsulo zolemera ndi madzi otayira ovuta

Madzi otayira pogwiritsa ntchito ma electroplating/metallurgical

Chopopera cha mchere wambiri chingawononge copper-ammonia complex (chokhazikika pamene pH = 11), ndikuyambitsa ma ayoni achitsulo cholemera (monga Cu²⁺, Cr⁶⁺) kudzera mu electro-neutralization.

Njira: pali Fe³⁺ yochepa yaulere, ndipo makamaka imadalira kulowetsedwa ndi kumangidwa kwa unyolo wa polima.

Muli ndi phosphorous Madzi Otayira a Mafakitale

Pamene zinthu zosasungunuka (monga FePO₄) zimapangidwa ndi phosphate, kuchuluka kwa phosphorous (>10mg/L) komwe kumachotsedwa kumakhala koposa 95% pamene mchere uli woposa kapena wofanana ndi 14%.

🌊 4. Ubwino wa madzi a alkaline (pH>9)

Kugwiritsa Ntchito: Flocculant yokhala ndi kuchuluka kwa mchere wambiri imatha kusungabe mphamvu yokhazikika ya flocculation pakati pa pH 9-11, ndikupewa kulephera kwa hydrolysis ya iron ion chifukwa cha kuchuluka kwa pH muzinthu zokhala ndi kuchuluka kwa mchere wotsika.

Zochitika wamba: madzi otayira amchere, kupanga mapepala a zakumwa zakuda.

🌿 5. Madzi oipitsidwa pang'ono ndi magwero a madzi okhala ndi algae

Madzi a Eutrophic

Khoma la maselo a algae (monga cyanobacteria ndi diatoms) lili ndi mphamvu yoyamwa madzi, ndipo dothi limakulitsidwa mwachangu chifukwa cha maluwa a algae omangika kuti aphimbe maselo a algae.

Madzi owonongeka pang'ono ndi zinthu zachilengedwe

Imatha kuchotsa bwino zinthu zachilengedwe (CODMn

⚠ Malangizo ndi zoletsa

Gwero la deta: Machitidwe a uinjiniya akuwonetsa kuti flocculant yokhala ndi mchere wambiri iyenera kusinthidwa mosinthasintha —— mwachitsanzo, kukhuthala kwa madzi okhala ndi madzi ambiri nthawi yamvula kumatha kukwezedwa kufika pa 16%, koma kusungidwa kwa nthawi yayitali kuyenera kulamulidwa ≤16% kuti tipewe hydrolysis ndi mvula.
