I-Polyacrylamide Yokwelapha Amanzi Angcolile

I-Polyacrylamide (PAM), isibizo: i-flocculant, i-anion, i-cation,

i-polymer; Ama-polymers, ukugcinwa kanye nokuhlunga i-AIDS, i-AIDS yokugcina, ama-disperants; I-polymer, i-ejenti yokususa uwoyela, njll.

Izici ezithinta umphumela wokuhlanza indle:

1. Udaka luwumkhiqizo ongenakugwemeka wokuhlanza indle. Okokuqala, kufanele siqonde umthombo, imvelo, ukwakheka kanye nokuqukethwe okuqinile kwe-sludge. Ngokokwakheka okuyinhloko kwe-sludge, udaka lungahlukaniswa lube udaka oluphilayo kanye nodaka lwe-inorganic. Ngokuvamile, i-cationic polyacrylamide isetshenziselwa ukwelapha udaka oluphilayo, i-anionic polyacrylamide isetshenziselwa ukwelapha udaka lwezinto ezingaphili. Akulula ukusebenzisa i-cationic polyacrylamide uma i-alkaline inamandla kakhulu, futhi ayifaneleki ukusebenzisa i-anionic polyacrylamide uma okuqukethwe okuqinile kwe-sludge kuphezulu.

2. Ukukhethwa kwe-Ion degree: ukuze i-sludge ingabi namanzi, i-flocculant ene-ion degree ehlukene ingahlolwa ngokusebenzisa ukuhlolwa okuncane ukuze ukhethe i-polyacrylamide efanele, ukuze ifinyelele umphumela ongcono we-flocculant, kodwa futhi ingenza umthamo omncane, ukonga izindleko.

3. Ubukhulu bemihlambi: ama-flocs amancane kakhulu azothinta isivinini sokudonsa amanzi, ama-flocs ahlangane kakhulu ukuze ama-flocs abophe amanzi amaningi futhi anciphise izinga lamabhisikidi odaka. Ubukhulu be-flocs bungashintshwa ngokukhetha isisindo samangqamuzana e-polyacrylamide.

4. Amandla emihlambi: ama-flocs kufanele ahlale azinzile futhi angaphulwa ngaphansi kwesenzo sokugunda. Ukwandisa isisindo samangqamuzana e-polyacrylamide noma ukukhetha isakhiwo samangqamuzana esifanele kuyasiza ukuthuthukisa ukuzinza kwama-flocs.

5. Ingxube ye-polyacrylamide ne-sludge: i-polyacrylamide endaweni ethile yemishini yokukhipha amanzi emzimbeni kumele iphendule ngokugcwele nge-sludge, i-flocculation. Ngakho-ke, i-viscosity yesisombululo se-polyacrylamide kufanele ifaneleke, futhi ingaxutshwa ngokugcwele ne-sludge ngaphansi kwezimo ezikhona zemishini. Ukuthi kokubili kuxutshwe ngokulinganayo kuyisici esibalulekile sempumelelo. I-viscosity yesixazululo se-cationic polyacrylamide ihlobene nesisindo sayo samangqamuzana nokuhlushwa kokulungiselela.

6. Ukuqedwa polyacrylamide cationic: chaza kahle ukunikeza play ngokugcwele flocculation. Ngezinye izikhathi kuyadingeka ukusheshisa izinga lokuqedwa, lapho ukuhlushwa kwesisombululo se-polyacrylamide kungacatshangwa.
