Ntchito Mphamvu ya Pac mu Chithandizo Madzi a Morrmal Mphamvu Zomera

1. Chithandizo chothandizira madzi

Matupi achilengedwe amadzi nthawi zambiri amakhala ndi matope, dongo, humus ndi zinthu zina zoimitsidwa ndi mabakiteriya, ndiye chifukwa chachikulu m'madzi, utoto ndi fungo. Zinthu zolimbitsa thupi zolimbitsa thupi izi zimalowetsa Chuma, chodetsa utoto, kuchepetsa kuchuluka kwa utomoni, komanso kumakhudzanso kusintha kwa dongosolo la matebulo. Kugwiritsa ntchito mankhwalawa, kufotokozera kwadongosolo komanso chithandizo chokwanira ndikuchotsa zodetsazi kukhala cholinga chachikulu, kotero kuti zomwe zayimitsidwa m'madzi zimachepetsedwa mpaka 5mg / ndiye kuti, kujambula madzi. Izi zimatchedwa kukongoletsa madzi. Pambuyo pokonzedwa, madziwo amatha kugwiritsidwa ntchito ngati madzi owonda pokhapokha mchere wosungunuka m'madzi amachotsedwa ndi ion Kusinthana ndi mipweya yosungunuka m'madzi imachotsedwa potenthedwa kapena kuwononga. Ngati zosalephera sizichotsedwa choyamba, zomwe zimachitika (zosenda) sizingachitike. Chifukwa chake, mankhwala othandizira amadzi ndi gawo lofunikira m'madzi chithandizo chamadzi.

Njira yopangira mafuta yamatenthedwe ndi motere: Madzi osaphika → Kuchulukitsa → Kuchulukitsa ndi kufotokozera kwa → Kufalikira. Zovala zomwe zimagwiritsidwa ntchito potengera njira yolumikizira a polyiluminim cloride, polyferric sulfate, aluminiyamu sulfate, motero trichloride, etc.

Polyolumuminim chloride, otchulidwa ngati Pac, amatengera mchere wa aluminium a aluminium a phulusa ngati zida zopangira, komanso njira za aluminiyamu ndi njira zopangira ndizosiyana. Njira ya matola a pac [al2 (o) nci6-kwen m, pomwe n utha kukhala ndi nambala pakati pa 1 ndi 5, ndipo m ndi mitundu yolimba komanso yamadzimadzi.

2.Coagation

Pali zinthu zitatu zazikulu zokhala ndi colloidal tinthu tating'onoting'ono m'madzi: kudzipatula kwa magetsi, Adsorration Storing ndi kusesa. Ndi iti mwa izi zomwe ndizotengera zazikulu ndi mlingo wa coagulant, chikhalidwe ndi chidziwitso cha ma conloidal tinthu tambiri m'madzi, ndi mtengo wamadzi. Limagwirira la kuchitapo kwa polyoluminum chiloride limafanana ndi la aluminiyamu sulfate, ndipo machitidwe a aluminiyamu salfate m'madzi amatanthauza mitundu yonse ya ma hydrolyje.

Polyolumuminim chloride imadziwika kuti ndi zinthu zosiyanasiyana zapakatikati mu hydrolysis ndi polymerization wa aluminiyam chloride kukhala al (o) 3 pamikhalidwe ina. Amapezeka mwachindunji m'madzi mu mawonekedwe amitundu yosiyanasiyana ya polymeric ndi A1 (o) a (s), popanda hydroly planter of AL3.

3. Ntchito ndi Zochititsa chidwi

1. Kutentha kwamadzi

Kutentha kwamadzi kukukhumudwitsidwa pamavuto. Kutentha kwamadzi kumakhala kotsika, hydrolysis ya combelant kumakhala kovuta kwambiri, makamaka ngati kutentha kwamadzi kumakhala kochepa kwambiri, ndipo mawonekedwe opangidwa ndi malowa amakhala ndi zigawo zabwino. Kutentha kwamadzi kumakhala kotsika, kunyalikira kwa ma conloidal tinthu tating'onoting'ono kumakulitsidwa, nthawi yopuma imakhala yayitali, ndipo kuderera kumakhala kochepa kwambiri. Kafukufukuyu akuwonetsa kuti kutentha kwamadzi kwa 25 ~ 30 ℃ kuli koyenera kwambiri.

2. Mtengo wa Madzi

Njira ya hydrolysis ya polyolumuminim cloride ndi njira yomasulira H +. Chifukwa chake, pansi pa pH yosiyanasiyana, padzakhala njira yosiyana ndi ma hydrolysis, ndipo mtengo wabwino kwambiri wa Pulsaluminum clor chloride mankhwala nthawi zambiri pakati pa 6.5 ndi 7.5. Zotsatira zophatikiza ndizokwera pakadali pano.

3. Mlingo wa cosulant

Kuchuluka kwa coaglant kuwonjezeredwa sikokwanira, kukwiya kotsalira m'madzi ndi kokulirapo. Ndalamazo zikakhala zokulirapo, chifukwa tinthu tating'onoting'ono timadzi toyambitsa matenda a Adsorb ochulukirapo, malo ogulitsira a conlorb amasintha, zomwe zimapangitsa kuti zitheke. Njira yogwiritsira ntchito kuphatikizapo siyosavuta ya mankhwala, kotero kuti Mlingo wofunikira sangathe kutsimikizika molingana ndi kuwerengera, koma ayenera kutsimikizika molingana ndi mtundu wina wa madzi kuti mudziwe mlingo woyenera; Madzi abwino akasintha mwachinyengo, Mlingo uyenera kusinthidwa moyenerera.

4. Lumikizanani ndi sing'anga

Mukamagwiritsa ntchito mankhwalawa kapena chithandizo china, ngati pali kuchuluka kwa matope m'madzi, zotsatira za chithandizo chamankhwala chitha kukhala bwino kwambiri. Itha kupereka malo akuluakulu, kudzera mwa adsorption, catalysis ndi crystallung, kusintha mphamvu ya chithandizo chamankhwala.

Kukhazikika kwa chipongwe ndi njira yogwiritsidwa ntchito kwambiri kwa mankhwalawa madzi pakadali pano. Makampani ogulitsa a polyilumuyamu amagwiritsidwa ntchito ngati chithandizo chamadzi chokhala ndi nyumba, ndikugwiritsa ntchito bwino, kuchuluka kwa chakudya, kuchuluka kwa njira zambiri, mtengo wake ungasungidwe 40%. Kuphatikizidwa ndi kugwiritsidwa ntchito kwa kasefa kapena kuwongolera madzi a kaboni, mawonekedwe a madzi osaphika amachepetsedwa kwambiri, mawonekedwe a dongosolo la dardalt amayenda bwino, ndipo kusinthitsa mphamvu ya Dessalt imakulanso, ndipo mtengo wogwiririra umachepa.
