Polycrylamide yokwelashwa kwamanzi amdaka

I-PolyAcrylamide (Pam), Alias: I-Flocculant, ANONION, CATAN,

polymer; Ama-polymers, ukugcinwa kanye ne-FILTRATION AIDS, izinsiza-kugcinwa, ama-dispersants; I-Polymer, i-ejenti yokuxoshwa kawoyela, njll.

Izici ezithinta umphumela wokwelashwa kwendle:

1. I-Sludge ingumkhiqizo ongenakugwemeka wokwelashwa kwendle. Okokuqala, kufanele siqonde umthombo, imvelo, ukwakheka nokuqukethwe okuqinile kwe-sludge. Ngokusho kokwakheka okuyinhloko kwe-sludge, i-sludge ingahlukaniswa ibe yi-organic sludge kanye ne-inorganic sludge. Ngokuvamile, i-cationic polyyacrylamide isetshenziselwa ukwelashwa kwe-organic sludge, i-anionic polyyamide isetshenziselwa ukwelashwa kwe-inorganic sludge. Akulula ukusebenzisa i-cationic polylamide lapho i-alkaline iqine kakhulu, futhi ayifanele ukusebenzisa i-anionic polylacrylamide lapho okuqukethwe okuqinile kwe-sludge kuphezulu.

2. Ukukhethwa kweziqu ze-Ion

3 Ubungako bama-flocs bungashintshwa ngokukhetha isisindo se-polycacide.

4. Amandla ama-flocs: ama-flocs kufanele ahlale azinzile futhi aphuliwe ngaphansi kwesenzo se-shear. Ukwandisa isisindo se-molecular of polysamide noma ukhetha isakhiwo esifanelekile samangqamuzana siyasiza ukuthuthukisa ukuqina kwama-flocs.

I-5. Ingxube ye-polyracrylamide ne-sludge: I-Polylamide endaweni ethile yemishini yokuphelelwa amandla kufanele iphendulwe ngokuphelele nge-sludge, i-floccution. Ngakho-ke, ukubonwa kwesixazululo se-polyracrylamide kumele kube kufanelekile, futhi kungahlanganiswa ngokuphelele ne-sludge ngaphansi kwemibandela yemishini ekhona. Ukuthi laba bobabili baxubene ngokulinganayo yini into esemqoka yempumelelo. I-viscosity ye-cationic polyyamide solution ihlobene nesisindo sayo samangqamuzana kanye nokuhlushwa kokulungiselela.

6 Kwesinye isikhathi kuyadingeka ukusheshisa izinga lokuchithwa, lapho kubhekwa ukugcwala kwe-polylacrylide solution.
