Polyacrylamide- Udindo wa Sewage Flocculants

Pofuna kutulutsa kapena kugwiritsiranso ntchito Madzi onyansa pambuyo pa Kuchiza, Mankhwala osiyanasiyana amayenera kugwiritsidwa ntchito pokonza njira ya Madzi a Madzi.Lero,PAM (Polyacrylamide) ogulitsaadzakuuzani za flocculants:

Flocculant: Nthawi zina amatchedwanso coagulant, itha kugwiritsidwa ntchito ngati njira yolimbikitsira kulekanitsa kwamadzi olimba, ndipo imatha kugwiritsidwa ntchito ngati thanki yokhazikika, tanki yokhazikika yachiwiri, thanki yoyandama, chithandizo chamankhwala apamwamba kapena chithandizo chamankhwala apamwamba ndi maulalo ena.

Flocculants ntchito ngati njira kulimbikitsa olimba-zamadzimadzi kulekana m`munda wa zimbudzi mankhwala.Iwo angagwiritsidwe ntchito kulimbikitsa pulayimale sedimentation zimbudzi, mankhwala flotation ndi sedimentation yachiwiri pambuyo adamulowetsa sludge ndondomeko, ndipo angagwiritsidwe ntchito pa maphunziro apamwamba kapena mankhwala apamwamba a zimbudzi.Akagwiritsidwa ntchito pokonza matope asanayambe kutaya madzi m'thupi, ma flocculants ndi ma coagulants amakhala oyeretsa kapena kuchepetsa madzi m'thupi.

Mukamagwiritsa ntchito ma flocculants achikhalidwe, njira yowonjezerera zothandizira coagulant ingagwiritsidwe ntchito kukulitsa mphamvu ya flocculation.Mwachitsanzo, kugwiritsa ntchito silicic acid ngati coagulant yothandizira ma inorganic flocculants monga ferrous sulfate ndi aluminiyamu sulphate ndikuwonjezera motsatizana kungathe kukwaniritsa bwino.Chifukwa chake, m'mawu a layman, inorganic polymer flocculant IPF imakonzedwa pophatikiza chithandizo cha coagulant ndi flocculant ndikuwonjezedwa palimodzi kuti muchepetse ntchito ya wosuta.

Chithandizo cha coagulation nthawi zambiri chimayikidwa kutsogolo kwa malo olekanitsa olimba-zamadzimadzi, ndikuphatikizidwa ndi malo olekanitsa, amatha kuchotsa zolimba zolimba ndi zinthu za colloidal ndi tinthu tating'onoting'ono ta 1nm mpaka 100μm m'madzi yaiwisi, kuchepetsa turbidity ndi CODCr, ndipo angagwiritsidwe ntchito pretreatment wa zimbudzi njira.Chithandizo, chithandizo chapamwamba, chingagwiritsidwenso ntchito pochiza matope otsalira.Chithandizo cha coagulation chingathenso kuchotsa tizilombo toyambitsa matenda ndi tizilombo toyambitsa matenda m'madzi, ndikuchotsa mafuta opangidwa ndi emulsified, chroma, ayoni zitsulo zolemera ndi zoipitsa zina m'zimbudzi.Mlingo wochotsa phosphorous womwe uli m'chimbudzi ukhoza kufika 90% pamene coagulation sedimentation imagwiritsidwa ntchito pochiza phosphorous.~ 95%, ndiyo njira yotsika mtengo komanso yothandiza kwambiri yochotsera phosphorous.

Pokonzekera zonyansa, othandizira ena adzagwiritsidwa ntchito.Lero, aPAM Manufactureranayambitsa imodzi yokha ya izo.Kodi mukumvetsabe?Samalani ku Yuncang ndikuyankhani zambiri zachimbudzi kwa inu!
