Nhazi nhazi maka ngwa anionic polyacrylamide

A na-ejikarị polyacrylamide anionic eme ihe maka ime ka nsị mmiri sie ike, o nwere njirimara nke polymer electrolyte na etiti na-anọpụ iche na alkaline, na-enwe mmetụta na nnu electrolytes, a pụkwara ijikọ ion ígwè dị elu na gel a na-anaghị agbaze agbaze, nke a na-ejikarị eme ihe maka mmiri mmepụta n'ime ụlọ, ọgwụgwọ nsị ụlọ ọrụ na obodo ukwu, a pụkwara iji ya mee ihe maka mmiri nsị na-adịghị mma.

Isi ihe atọ dị mkpa maka ojiji nke anionic polyacrylamide:

N'ụlọ ọrụ mmepụta ihe nkedo na ígwè, a na-eji ya eme ka mmiri ịsa gas dị ọcha n'ime ọkụ ọkụ mepere emepe, mee ka mmiri mkpofu dị ọcha n'ime osisi ígwè ntụ ntụ na osisi ịcha mkpụrụ osisi, ime ka electrolytes dị ọcha na ime ka mmiri mkpofu dị ọcha.

N'ọrụ igwu ala, a na-eji ya maka ịsacha mmiri na ịgbasa coal, nzacha kol dị ọcha, ịkpọnwụ mmiri (slag), ịgbasa mmiri n'elu ikpo ọkụ, ịgbasa mmiri n'elu ikpo ọkụ, ịgbasa mmiri n'elu ikpo ọkụ, ịgbasa mmiri n'elu ikpo ọkụ, ịgbasa mmiri n'elu ikpo ọkụ, ịgbasa mmiri n'elu ikpo ọkụ, ịgbasa mmiri n'elu ikpo ọkụ, ịgbasa mmiri n'elu ikpo ọkụ, ịgbasa mmiri n'elu ikpo ọkụ, ịgbasa mmiri n'elu ikpo ọkụ, ịgbasa mmiri n'elu ikpo ọkụ na ịgbasa mmiri n'elu ikpo ọkụ, ịgbasa mmiri n'elu ikpo ọkụ na ịgbasa mmiri n'elu ikpo ọkụ, ịgbasa mmiri n'elu ikpo ọkụ na ịgbasa mmiri n'elu ikpo ọkụ, ịgbasa mmiri n'elu ikpo ọkụ na ịgbasa mmiri n'elu ikpo ọkụ, ịgbasa mmiri n'elu ikpo ọkụ na ịgbasa mmiri n'elu ikpo ọkụ site na phosphate.

N'ọgwụgwọ mmiri mkpofu obodo na nke ụlọ ọrụ mmepụta ihe, a na-eji ya eme ka mwepụ nke ihe siri ike a kwụnyere, BOD na phosphate dịkwuo mma n'ime mmiri mkpofu.

Site na ịgbakwunye 0.3mg/L anionic polyacrylamide na tankị mmiri mkpofu nke abụọ, enwere ike ịbawanye ọnụego mwepụ nke ihe a kwụnyere na BOD ruo 87% na 91%, n'otu n'otu, enwere ike ịbawanye mmetụta mwepụ phosphorus site na 35% ruo 91%. N'ọgwụgwọ mmiri ọṅụṅụ na mmiri mkpofu n'ụlọ, a na-eji ya eme ka elu dị ọcha, ịkọwapụta mmiri mkpofu na nhazi nzacha.

A na-enye ọgwụ polyacrylamide anionic ohere ịgbaze:
