Polyacrylamide maka ọgwụgwọ mmiri mkpofu

Polyacrylamide (PAM), utu aha: flocculant, anion, cation,

polymer;Polymers, njide na filtration AIDS, njide AIDS, dispersants;Polymer, onye nnọchi anya mmanụ, wdg.

Ihe na-emetụta mmetụta ọgwụgwọ nsị mmiri:

1. Sludge bụ ngwaahịa a na-apụghị izere ezere nke ọgwụgwọ nsị.Nke mbụ, anyị kwesịrị ịghọta isi iyi, ọdịdị, mejupụtara na ọdịnaya siri ike nke sludge.Dị ka isi mejupụtara nke sludge, sludge nwere ike kewaa organic sludge na inorganic sludge.N'ikwu okwu n'ozuzu, a na-eji cationic polyacrylamide mee ihe maka ọgwụgwọ nke sludge organic, a na-eji polyacrylamide anionic maka ọgwụgwọ sludge inorganic.Ọ dịghị mfe iji cationic polyacrylamide mgbe alkaline siri ike, ọ dịghịkwa mma iji polyacrylamide anionic mgbe ọdịnaya siri ike nke sludge dị elu.

2. Nhọrọ ogo ion: maka sludge ka mmiri na-ekpo ọkụ, flocculant nwere ogo ion dị iche iche nwere ike ikpuchi site na obere nnwale iji họrọ polyacrylamide kwesịrị ekwesị, ka o wee nweta mmetụta flocculant ka mma, kamakwa ọ nwere ike ime ka usoro ọgwụgwọ dị ntakịrị, ịzọpụta ọnụ ahịa.

3. Ogo nke flocs: flocs dị obere ga-emetụta ọsọ nke drainage, flocs kwa nzuko n'ozuzu na flocs na-ekekọta mmiri karịa ma belata ogo biscuit apịtị.Enwere ike ịhazi nha nke flocs site na ịhọrọ ịdị arọ nke polyacrylamide.

4. Ike nke flocs: flocs kwesịrị ịnọgide na-eguzosi ike ma ghara agbajikwa n'okpuru ọrụ nke shear.Ịbawanye ịdị arọ molekụla nke polyacrylamide ma ọ bụ ịhọrọ nhazi molekụla kwesịrị ekwesị na-enyere aka melite nkwụsi ike nke flocs.

5. Ngwakọta nke polyacrylamide na sludge: polyacrylamide n'ọnọdụ ụfọdụ nke akụrụngwa nkụ ga-emerịrị nke ọma na sludge, flocculation.Ya mere, viscosity nke polyacrylamide ngwọta ga-adabara, na ọ nwere ike ịgwakọta ya na sludge n'ụzọ zuru ezu n'okpuru ngwaọrụ dị ugbu a ọnọdụ.Ma a gwakọtara ha abụọ n'otu n'otu bụ isi ihe maka ịga nke ọma.Viscosity nke ngwọta cationic polyacrylamide metụtara ịdị arọ molekụla ya na ntinye nkwadebe ya.

6. Mgbasa nke cationic polyacrylamide: gbazee nke ọma iji nye egwuregwu zuru oke na flocculation.Mgbe ụfọdụ, ọ dị mkpa iji mee ka ọnụego mgbasa dị ngwa ngwa, mgbe enwere ike ịtụle ntinye nke ngwọta polyacrylamide.
