Njira ndi kugwiritsa ntchito PolyDADMAC mu chithandizo cha madzi

Polydiallyldimethylammonium chloride(PolyDADMAC) ndi chinthu chogwiritsidwa ntchito kwambiri chotchedwa cationic polymer flocculant ndipo chimagwira ntchito yofunika kwambiri pa ntchito yokonza madzi. PDADMAC nthawi zambiri imagwiritsidwa ntchito ngati flocculant ndipo nthawi zina imaphatikizidwa ndi algaecides. Nkhaniyi ifotokoza za ubwino ndi kufunika kogwiritsa ntchito PolyDADMAC kuchokera ku mbali za momwe imagwirira ntchito, zochitika zogwiritsira ntchito komanso njira zina zowongolera magwiridwe antchito a mankhwala okonza madzi.

Makhalidwe ofunikira a PolyDADMAC

PolyDADMAC ndi polima yokhala ndi mamolekyulu ambiri okhala ndi magulu ambiri a cationic mu kapangidwe kake ka mamolekyulu, omwe amatha kuyamwa bwino tinthu tating'onoting'ono ndi ma colloid omangika m'madzi. Makhalidwe ake akuluakulu ndi awa:

1. Kukhazikika kwamphamvu: Imatha kuletsa mwachangu tinthu tomwe timayimitsidwa m'madzi tokhala ndi mphamvu yoipa.

2. Kusungunuka bwino kwa madzi: N'zosavuta kusungunuka m'madzi ndipo ndi yabwino kugwiritsa ntchito pamalopo.

3. Kukhazikika kwa mankhwala: Imatha kusunga magwiridwe antchito a flocculation yogwira ntchito bwino kwambiri m'malo osiyanasiyana a pH, malo osungira okosijeni komanso malo okhala ndi makina ambiri. PDADMAC ili ndi kukana kwamphamvu kwa chlorine.

4. Kuopsa kochepa: Imakwaniritsa miyezo yoteteza chilengedwe ndipo ndi yoyenera kutsukidwa ndi madzi akumwa.

Njira yogwirira ntchito ya PolyDADMAC pochiza madzi

Zimasokoneza tinthu tomwe timapachikidwa ndi zinthu zamadzi zomwe zimakhala ndi mphamvu yoipa m'madzi ndipo zimayandama kudzera mu kuletsa magetsi ndi kutsekereza madzi. Zimakhala ndi zotsatira zazikulu pakuchotsa utoto, komanso kuchotsa zinthu zachilengedwe.

PolyDADMACkumawonjezera mphamvu ya kuyeretsa madzi pogwiritsa ntchito njira zotsatirazi:

1. Kuletsa kubweza

Tinthu tating'onoting'ono tomwe timapachikidwa m'madzi nthawi zambiri timakhala ndi ma charge oipa, zomwe zimayambitsa kukana pakati pa tinthu tating'onoting'ono ndipo zimapangitsa kuti zikhale zovuta kukhazikika. Magulu a cationic a PolyDADMAC amatha kuletsa ma charge oipa mwachangu, kuchepetsa kukana kwa electrostatic pakati pa tinthu tating'onoting'ono, ndikulimbikitsa kuuma kwa tinthu tating'onoting'ono.

2. Kugwirizanitsa

Kapangidwe ka molekyulu yayitali ya PolyDADMAC yokhala ndi ma viscosity apamwamba imapangitsa kuti ipange "mlatho" pakati pa tinthu tambirimbiri, kuphatikiza tinthu tating'onoting'ono kukhala ma flocs akuluakulu, motero kumathandizira kuti sedimentation igwire bwino ntchito.

3. Kulimbitsa zotsatira za kugwidwa kwa intaneti

PolyDADMAC ikhoza kulimbitsa "kapangidwe ka ukonde" komwe kamapangidwa ndi coagulant yopanda chilengedwe pochiza madzi kuti igwire bwino zinthu zosungunuka bwino, makamaka m'madzi okhala ndi dothi lalikulu kapena oipitsidwa kwambiri.

Zochitika zogwiritsira ntchito PolyDADMAC

1. Kuchiza madzi akumwa

PolyDADMAC imagwiritsidwa ntchito ngati flocculant kuti ichotse matope, tinthu tomwe timapachikidwa ndi zinthu zachilengedwe m'madzi akumwa. Nthawi yomweyo, chifukwa cha poizoni wake wochepa komanso mawonekedwe ake oteteza chilengedwe, imatha kukwaniritsa miyezo yotetezeka ya madzi akumwa.

2. Kukonza madzi otayira

Pochiza madzi otayira m'maboma ndi m'mafakitale, PolyDADMAC nthawi zambiri imagwiritsidwa ntchito kukonza ntchito yochotsa madzi m'matope, kuchepetsa chinyezi cha keke yamatope, komanso kuchepetsa kwambiri ndalama zogwirira ntchito.

3. Kuyeretsa madzi m'mafakitale

Mu mafakitale amagetsi, petrochemical ndi mafakitale ena, PolyDADMAC imagwiritsidwa ntchito poyeretsa madzi a mafakitale monga madzi ozizira ndi madzi a boiler kuti achepetse kufalikira kwa madzi ndi dzimbiri.

4. Makampani opanga mapepala ndi nsalu

PolyDADMAC imagwiritsidwa ntchito ngati chithandizo chosungira ndi kusefera kuti chiwongolere kuchuluka kwa ulusi ndi zodzaza zomwe zimasungidwa popanga mapepala, pomwe kuchepetsa kuchuluka kwa zinthu zomwe zimayimitsidwa m'madzi otayira.

Njira zowongolera bwino njira zochizira madzi pogwiritsa ntchito PolyDADMAC

1. Kukonza bwino kulamulira mlingo

Mlingo wa PolyDADMAC umagwirizana kwambiri ndi kuchuluka kwa tinthu tating'onoting'ono, kufalikira kwa tinthu tating'onoting'ono ndi makhalidwe a zinthu zoipitsa madzi zomwe zimayikidwa m'madzi. Kukonza mlingo pogwiritsa ntchito mitsuko kungathandize kuti madzi asasunthike bwino komanso kupewa kuchuluka kwa zinthu zomwe zimapangitsa kuti madzi aziwonongeka kwambiri.

2. Mphamvu yogwirizana ndi zinthu zopanda chilengedwe

Kugwiritsa ntchito PolyDADMAC pamodzi ndi ma flocculants osapangidwa ndi zinthu zachilengedwe (monga polyaluminium chloride ndi aluminium sulfate) kungathandize kwambiri kuti flocculation ichitike. Pambuyo poti PolyDADMAC yathetsa mphamvu ya pamwamba pa tinthu tating'onoting'ono, ma flocculants osapangidwa ndi zinthu zachilengedwe amapanga ma floc akuluakulu kudzera mu kulowetsedwa ndi kutayidwa kwa nthaka.

3. Kukweza kuchuluka kwa njira zochizira madzi zokha

Mothandizidwa ndi machitidwe odzilamulira okha, kuyang'anira ndi kusintha kwa mlingo wa PolyDADMAC nthawi yeniyeni kungathe kuchitika kuti athe kuthana ndi kusintha kwa magwiridwe antchito a mankhwala chifukwa cha kusinthasintha kwa khalidwe la madzi.

4. Konzani bwino momwe mungapangire zinthu zosakaniza

Pambuyo powonjezera PolyDADMAC, mphamvu yoyenera yosakaniza ndi nthawi yake zitha kuwonjezera kufalikira kwake komanso kugwira ntchito bwino kwa flocculation. Kusakaniza kwambiri kungayambitse floc kusweka, pomwe kusakaniza kosakwanira kumachepetsa mphamvu yosakaniza.

5. Sinthani pH

PolyDADMAC imagwira ntchito bwino kwambiri m'madzi opanda asidi kapena amchere pang'ono. Pochiza madzi okhala ndi asidi wambiri kapena amchere wambiri, kusintha pH ya madzi m'thupi kungathandize kwambiri kuti flocculation yake igwire bwino ntchito.

Ubwino wa PolyDADMAC

1. Kuchita bwino kwambiri: Kupanga mwachangu kwa ma floc kuti akonze bwino kulekanitsa kwa madzi olimba ndi olimba.

2. Ntchito zosiyanasiyana: Imagwira ntchito pamitundu yosiyanasiyana yamadzi, makamaka madzi okhala ndi dothi lochuluka komanso zinthu zambiri zachilengedwe.

3. Kuteteza chilengedwe: Kuchepa kwa poizoni ndi kuwonongeka kwa zinthu, mogwirizana ndi zofunikira zoteteza chilengedwe.

Monga njira yothandiza kwambiriflocculant, PolyDADMAC ili ndi ubwino waukulu wogwiritsidwa ntchito pochiza madzi chifukwa cha mphamvu yake yokhudza kuyeretsa madzi, kusungunuka bwino kwa madzi komanso kugwiritsidwa ntchito bwino. Kudzera mu njira zoyenera zokonzera ndi kugwiritsa ntchito njira, mphamvu yake yochizira madzi akumwa, zimbudzi ndi madzi amafakitale ikhoza kuwonjezeredwa.
