Nhazi nhazi maka ngwa anionic polyacrylamide

Anionic polyacrylamide bụ tumadi eji maka ike flocculation nke nsị, o nwere e ji mara nke polymer electrolyte na-anọpụ iche na alkaline ọkara, mmetụta nke nnu electrolytes, na elu price metal ion nwere ike cross-jikọrọ n'ime insoluble gel, nke a na-bụ-eji maka ụlọ mmepụta. mmiri, ụlọ ọrụ mmepụta ihe na ọgwụgwọ nsị nke obodo mepere emepe, na enwere ike iji ya mee ihe maka akpịrị ịkpọ nkụ.

Akụkụ atọ bụ isi ngwa nke anionic polyacrylamide:

N'ime ụlọ ọrụ na-emepụta ihe nkedo na ígwè, a na-eji ya maka nhicha nke mmiri ịsacha gas n'ime ọkụ ọkụ na-emeghe, nkọwa nke mmiri mkpofu na osisi metallurgy ntụ ntụ na osisi pickling, nchacha nke electrolytes na nkọwa nke mmiri mmiri electroplating.

Na Ngwuputa ihe, a na-eji ya maka ịkọwa mmiri na-asachapụ mmiri na flotation tailings, coal filtration dị ọcha, ọdụ (slag) akpịrị ịkpọ nkụ, flotation tailings nkọwa, itinye uche thickening na filtration, potassium alkali na-ekpo ọkụ gbazee na flotation nhazi mmiri nkọwa, fluorite na barite flotation ọdụ ọdụ nkọwa. , raw brine maka nhazi nnu, nkọwa nke akpịrị ịkpọ nkụ sludge na ọgwụgwọ mmiri mgbake nke phosphate.

N'ime ime obodo na ụlọ ọrụ mmepụta ihe, a na-eji ya emeziwanye mwepụ nke ihe ndị a kwụsịrị, BOD na phosphate na mmiri mmiri.Site n'ịgbakwunye 0.25mg/L hydrolyzed polyacrylamide na isi mmiri sedimentation tank, mwepụ nke ihe kwụsịtụrụ na BOD nwere ike mụbaa na 66% na 23% n'otu n'otu.Site n'ịgbakwunye 0.3mg / L anionic polyacrylamide na mmiri mmiri na-ekpo ọkụ nke abụọ na-edozi mmiri na-ekpofu mmiri, enwere ike ịbawanye ọnụ ọgụgụ nke ihe nkwụsịtụ na BOD ruo 87% na 91%, n'otu n'otu, na mmetụta mwepụ nke phosphorus nwere ike ịbawanye site na 35% ruo 91%. .N'ime ọgwụgwọ nke mmiri ọṅụṅụ na mmiri mkpofu ụlọ, a na-eji ya mee ihe maka nkọwa elu, nkọwa nke ikpochapụ mmiri na-ekpo ọkụ na nhazi nhazi.

Ewebata solubility nke anionic polyacrylamide nkwadebe:

1, ejiri mee ihe na mkpofu mmiri, nha akwadoro nke 0.1%

2, buru ụzọ fesa ntụ ntụ n'ime mmiri mgbata, ma kpalie na ọsọ ọsọ nke 40-60 RPM iji mee ka polymer gbazee n'ụzọ zuru ezu na mmiri tupu enwee ike ịgbakwunye ya.

3, N'oge nnwale ahụ, were mmiri mkpofu 100ml, gbakwunye 10% polyacrylamide solution, wee jiri nwayọọ kpalie, jiri sirinji jiri nwayọọ tinye ngwọta PAM, 0.5ml oge ọ bụla, dịka nha nke ifuru alum emepụtara na nso nso nke flocculant, ihe doro anya nke supernitant, ọnụ ọgụgụ sedimentation, usoro onunu ogwu iji chọpụta onye ọrụ kwesịrị ekwesị.
