Ma polyacrylamide flocculants ndi othandiza kwambiri pochotsa madzi m'matope ndi kukhazikika kwa zimbudzi. Makasitomala ena amanena kuti polyacrylamide pam yomwe imagwiritsidwa ntchito pochotsa madzi m'matope imakumana ndi mavuto ena. Lero, ndisanthula mavuto angapo omwe aliyense amakumana nawo.
1. Mphamvu ya flocculation ya polyacrylamide si yabwino, ndipo chifukwa chiyani singathe kukanikiza mu matope? Ngati mphamvu ya flocculation si yabwino, choyamba tiyenera kuthetsa mavuto a khalidwe la flocculant yokha, kaya cationic polyacrylamide ikukwaniritsa muyezo wa ionic molecular weight, komanso mphamvu ya matope yochotsa madzi ya mankhwala omwe sakukwaniritsa muyezo. Sizabwino kwenikweni. Pankhaniyi, kusintha PAM ndi mulingo woyenera wa ion kungathe kuthetsa vutoli.
2. Ndiyenera kuchita chiyani ngati kuchuluka kwa polyacrylamide kuli kwakukulu kwambiri?
Kuchuluka kwakukulu kumatanthauza kuti kuchuluka kwa index ya chinthucho sikukwanira, ndipo pali kusiyana pakati pa index zomwe zimafunikira kuti polyacrylamide ndi sludge flocculation ziume. Pakadali pano, muyenera kusankha mtundu kachiwiri, kusankha chitsanzo choyenera cha PAM ndi kuchuluka kowonjezera kuti muyese, ndikupeza mtengo wotsika wogwiritsira ntchito. Nthawi zambiri, tikulimbikitsidwa kuti kuchuluka kwa polyacrylamide komwe kwasungunuka kukhale kwa chikwi chimodzi mpaka chikwi ziwiri, ndipo kusankha kocheperako kumachitika malinga ndi kuchuluka kumeneku, ndipo zotsatira zomwe zapezeka zimakhala zomveka.
3. Kodi ndiyenera kuchita chiyani ngati kukhuthala kwa matope pambuyo pogwiritsa ntchito polyacrylamide pochotsa madzi m'matope kuli kokwera?
Izi zimachitika chifukwa cha kuwonjezera kwambiri kwa polyacrylamide kapena mankhwala osayenera ndi matope. Ngati kukhuthala kwa matope kumachepa mutachepetsa kuchuluka kwa matope, ndiye kuti ndi vuto la kuchuluka kwa matope. Ngati kuchuluka kwa matope kwachepetsedwa, zotsatira zake sizikupezeka ndipo matope sangathe kukanikiza, ndiye kuti ndi vuto la kusankha mankhwala.
4. Polyacrylamide imawonjezedwa ku matope, ndipo madzi omwe ali mu keke yotsatira yamatope ndi okwera kwambiri, ndiyenera kuchita chiyani ngati keke yamatope si youma mokwanira?
Pankhaniyi, choyamba yang'anani zida zochotsera madzi m'thupi. Makina a lamba ayenera kuwona ngati kutambasuka kwa nsalu yochotsera madzi sikukwanira, kulowa kwa madzi mu nsalu yochotsera madzi komanso ngati nsalu yochotsera madzi ikufunika kusinthidwa; makina osindikizira a mbale ndi chimango ayenera kuwona ngati nthawi yothira fyuluta ndi yokwanira, ngati kuthamanga kwa fyuluta ndi koyenera; makina oyeretsera madzi ayenera kuwona ngati kusankha kwa chotsukira madzi m'thupi ndikoyenera. Zipangizo zomangira ndi zotsukira madzi m'thupi zimayang'ana kwambiri kuwona ngati kulemera kwa mamolekyu a polyacrylamide ndi kokwera kwambiri, komanso ngati zinthu zomwe zili ndi kukhuthala kwakukulu sizikugwirizana ndi matope okanikiza!
Pali mavuto ambiri ofala a polyacrylamide pakuchotsa madzi m'matope. Mavuto omwe ali pamwambawa ndi omwe amafala kwambiri komanso mayankho omwe afotokozedwa mwachidule muzosintha zambiri zomwe zikuchitika pamalopo. Ngati muli ndi mafunso okhudza kukanikiza kapena kuyika matope m'matope a polyacrylamide, zonse zomwe mungatumizire imelo kwa ife, tiyeni tikambirane za kugwiritsa ntchito polyacrylamide pakuchotsa madzi m'matope!
