Polyacrylamide Don Maganin Ruwan Shara

Polyacrylamide (PAM), wanda aka fi sani da: flocculant, anion, cation,

polymer; polymers, riƙewa da tacewa AIDS, riƙewar AIDS, masu rarrabawa; Polymer, wakili na sauya man fetur, da dai sauransu.

Abubuwan da ke shafar tasirin maganin najasa:

1. Sludge samfur ne na makawa na maganin najasa. Da farko, ya kamata mu fahimci tushen, yanayi, abun da ke ciki da kuma m abun ciki na sludge. Bisa ga babban abun da ke ciki na sludge, sludge za a iya raba zuwa kwayoyin sludge da inorganic sludge. Gabaɗaya magana, ana amfani da cationic polyacrylamide don maganin sludge na halitta, ana amfani da polyacrylamide anionic don maganin sludge na inorganic. Ba abu mai sauƙi ba ne don amfani da cationic polyacrylamide lokacin da alkaline yana da ƙarfi sosai, kuma bai dace da amfani da polyacrylamide anionic ba lokacin da ingantaccen abun ciki na sludge ya yi girma.

2. Zaɓin digiri na Ion: don sludge da za a dehydrated, flocculant tare da digiri daban-daban na ion za a iya nunawa ta hanyar ƙananan gwaji don zaɓar polyacrylamide da ya dace, don haka zai iya cimma sakamako mafi kyau na flocculant, amma kuma zai iya yin mafi ƙarancin sashi, ceton farashi.

3. Girman flocs: flocs ma ƙanƙanta zai shafi saurin magudanar ruwa, ɗumbin taron jama'a da yawa don ɗaure ruwa mai yawa kuma ya rage darajar biscuit laka. Ana iya daidaita girman flocs ta hanyar zabar nauyin kwayoyin polyacrylamide.

4. Ƙarfin raƙuman ruwa: flocs ya kamata su kasance a tsaye kuma kada su karye a ƙarƙashin aikin shear. Ƙara nauyin kwayoyin halitta na polyacrylamide ko zabar tsarin kwayoyin da ya dace yana taimakawa wajen inganta kwanciyar hankali na flocs.

5. Cakuda polyacrylamide da sludge: polyacrylamide a wani matsayi na kayan aikin bushewa dole ne a cika shi da sludge, flocculation. Sabili da haka, danko na maganin polyacrylamide dole ne ya dace, kuma ana iya haɗe shi da sludge a ƙarƙashin yanayin kayan aiki. Ko an gauraye su biyu daidai gwargwado shine mabuɗin nasara. Dankowar maganin polyacrylamide na cationic yana da alaƙa da nauyin kwayoyin sa da tattarawar shiri.

6. Rushewar cationic polyacrylamide: narke da kyau don ba da cikakken wasa ga flocculation. Wani lokaci yana da mahimmanci don hanzarta saurin rushewa, lokacin da za'a iya la'akari da ƙaddamar da maganin polyacrylamide.
