M'malo amakono, zovuta zachimbudzi zomwe zimayambitsidwa ndi chitukuko cha mafakitale zakhala zikugwiritsidwa ntchito bwino kunyumba ndi kunja. Ponena za izi, tiyenera kutchula udindo wa decolorizing flocculants mu mankhwala madzi. Kwenikweni, zimbudzi zopangidwa ndi mafakitale ambiri zimafunikira kugwiritsa ntchito ma decolorizing flocculants. Yixing Cleanwater idzakudziwitsani zomwe muyenera kudziwa komanso kugwiritsa ntchito m'magawo osiyanasiyana.
Zosiyanasiyana polima decolorizing flocculants chimagwiritsidwa ntchito m'munda wa madzi mafakitale ndi zimbudzi mankhwala kunja, pakati polyacrylamide (PAM) ndi mtundu waukulu wa decolorizing flocculant. Poyerekeza ndi miyambo inorganic mchere flocculants, PAM, monga mtundu watsopano wa wothandizila madzi mankhwala, ali ndi ubwino wambiri: yosavuta ndi yosavuta kugwiritsa ntchito, flocculation zotsatira ndi kangapo kuposa chikhalidwe chikhalidwe mchere decolorizing flocculants; kudya flocculation ndi sedimentation liwiro, mkulu sludge dewatering dzuwa; wapadera mankhwala zotsatira zina zimbudzi; zida zosavuta zofunika, zopondapo zazing'ono; mtengo wotsika wamankhwala; zimbudzi zitha kubwezeredwa ndi kugwiritsidwanso ntchito, ndi zina.
Kugwiritsa ntchito kwaPAM decolorizing flocculant m'magawo osiyanasiyana ogwiritsira ntchito:
1. Kugwiritsa ntchito makampani opanga mapepala
Kugwiritsa ntchito molekyulu yapamwamba ya PAM monga decolorizing flocculant kumatha kuwonjezera kuchuluka kwa mpweya wa pigment ndi zinthu zina m'madzi oyera ndikuchepetsa kutayika kwawo. Kuonjezera 0.25 ~ 0.5% PAM ku zamkati kungapangitse kuchuluka kwa sedimentation ya zamkati ndi 40 ~ 80 nthawi, kuchepetsa zolimba m'madzi oyera ndi pafupifupi 66%, kuonjezera phulusa la pepala, kuonjezera kuchuluka kwa kusungirako kwa inki monga dongo loyera ndi 8-18%, ndikusunga 20kg ya zamkati pa tani ya pepala. Komanso, mutatha kugwiritsa ntchito PAM, kutsekemera kwa madzi oyera kumachepetsedwa kwambiri, kuchepetsa kuwonongeka kwa chilengedwe. Mwachitsanzo, zolimba zoyimitsidwa zamadzi amkaka oyera amkaka amkaka okhala ndi pH=6.8 ndi 3000ppm. Pambuyo pothandizidwa ndi PAM ndi digiri ya hydrolysis ya 5 ~ 10%, kulemera kwa molekyulu ya 5.5 ~ 10 miliyoni, ndi 500ppm ya aluminium sulfate, madzi oyera amatha kusinthidwa kukhala madzi opanda mtundu komanso owoneka bwino, ndipo zolimba zoyimitsidwa zimachepetsedwa kukhala pansi pa 50ppm.
2. Kugwiritsa ntchito decolorizing flocculants mu mankhwala madzi
①Anti-scaling ndi descaling
M'madzi am'mafakitale ndi zonyansa, madzi osaphika ayenera kufotokozedwa poyamba. PAM decolorizing flocculants ndi inorganic coagulants nthawi zambiri ntchito osakaniza, amene angathe kuchepetsa kwambiri ntchito inorganic coagulants, kupewa blockage zida ndi dzimbiri chifukwa ntchito monyanyira coagulants inorganic, ndi kuteteza mapangidwe sikelo. Magawo 37.5 a PAM okhala ndi mamolekyu olemera omwe ali pansi pa 1 miliyoni ndi magawo 50 a sodium tripolyphosphate amagwiritsidwa ntchito popanga sikelo inhibitor, yomwe ingalepheretse kukula kwa osinthanitsa kutentha kwambiri.
②Chithandizo cha zimbudzi za mafakitale
3. Kugwiritsa ntchito ma decolorizing flocculants pochiza madzi oyipa m'makampani a shuga
Madzi a nzimbe omwe amachotsedwa m'mafakitale a shuga nthawi zambiri amakhala amphepo ndipo kapangidwe kake kamasokonekera. Kuti mupeze madzi a nzimbe aukhondo, pafunika kuwonjezeredwa zowunikira mankhwala. M'mbuyomu, ma inorganic decolorizing flocculants nthawi zambiri amagwiritsidwa ntchito, koma ndikukula kwamakampani a shuga, ma inorganic decolorizing flocculants sangathenso kukwaniritsa zosowa zopanga. M'zaka zaposachedwa, kugwiritsa ntchito PAM m'makampani a shuga kumatha kukulitsa kuchuluka kwa sedimentation ndi nthawi 20.
Mwachidule, tikasankha polyacrylamide PAM decolorization flocculant malinga ndi mmene zinthu zilili, tiyenera kusankha izo molingana ndi zochitika zosiyanasiyana ntchito ndi mikhalidwe. Choncho, kusankha polyacrylamide n'kofunika kwambiri.
Ngati mukufuna katundu wathu, chonde omasukaLumikizanani nafe!
