Polyacrylamide flocculants suna da tasiri sosai a cikin zubar da ruwa da najasa. Wasu abokan ciniki sun ba da rahoton cewa pam ɗin polyacrylamide da ake amfani da shi a cikin sludge dewatering zai gamu da irin waɗannan matsalolin da sauran matsaloli. A yau, zan bincika matsalolin gama gari da yawa ga kowa da kowa. :
1. Sakamakon flocculation na polyacrylamide ba shi da kyau, kuma menene dalilin da ya sa ba za a iya danna shi cikin sludge ba? Idan tasirin flocculation ba shi da kyau, dole ne mu fara kawar da matsalolin ingancin samfuran flocculant kanta, ko cationic polyacrylamide ya dace da ma'aunin nauyin kwayoyin ionic, da tasirin sludge dewatering na samfurin wanda bai dace da ma'auni ba tabbas ba shi da kyau. . A wannan yanayin, maye gurbin PAM tare da matakin ion mai dacewa zai iya magance matsalar.
2. Menene zan yi idan adadin polyacrylamide ya yi yawa?
Babban adadin yana nufin cewa index abun ciki na samfurin bai isa ba, kuma akwai tazara tsakanin fihirisar da ake bukata don polyacrylamide da sludge flocculation. A wannan lokacin, kuna buƙatar sake zaɓar nau'in, zaɓi samfurin PAM mai dacewa da ƙari adadin don gwadawa, kuma ku sami ƙarin amfani na tattalin arziki. farashi. Gabaɗaya, ana ba da shawarar cewa ƙwayar polyacrylamide da aka narkar da ita ita ce dubu ɗaya zuwa dubu biyu, kuma ana gudanar da ƙaramin zaɓi na gwaji bisa ga wannan taro, kuma sakamakon da aka samu ya fi dacewa.
3. Menene zan yi idan danko na sludge bayan amfani da polyacrylamide a cikin sludge dewatering yana da girma?
Wannan yanayin ya faru ne saboda ƙari da yawa na polyacrylamide ko samfurin da bai dace ba da sludge. Idan danko na sludge ya ragu bayan rage adadin adadin, to yana da matsala na adadin adadin. Idan an rage adadin ƙari, ba a sami sakamako ba kuma ba za a iya danna sludge ba, to yana da matsala na zaɓin samfurin.
4. Ana ƙara polyacrylamide a cikin sludge, kuma abun ciki na ruwa na cake na laka na gaba ya yi yawa, menene zan yi idan cake ɗin laka bai bushe ba?
A wannan yanayin, da farko duba kayan aikin bushewa. Na'urar bel ɗin yakamata ta bincika ko shimfiɗar rigar tacewa bai isa ba, dacewar ruwa mai tacewa da kuma ko ana buƙatar canza kayan tacewa; faranti da firam ɗin latsawa yana buƙatar bincika ko lokacin matsa lamba na tace ya isa, Ko matsi na tace ya dace; centrifuge yana buƙatar bincika ko zaɓin wakili na dehydrating ya dace. Stacked dunƙule da decanter dehydration kayan aikin mayar da hankali a kan duba ko kwayoyin nauyi na polyacrylamide ya yi yawa, kuma kayayyakin da ma high danko ba su dace da laka!
Har yanzu akwai matsaloli da yawa na gama gari na polyacrylamide a cikin sludge dewatering. Abubuwan da ke sama sune mafi yawan matsalolin gama gari da mafita waɗanda aka taƙaita a cikin adadi mai yawa na ɓarna a kan shafin. Idan kana da tambayoyi game da cationic polyacrylamide sludge pressing or sedimentation, duk Za ka iya aika saƙon imel zuwa gare mu, bari mu tattauna game da amfani da polyacrylamide a sludge dewatering!
