Ọgwụgwọ mmiri mkpofu ụlọ ọrụ – Flocculant (PAM)

N'ime mmiri mkpofu ụlọ ọrụ, a na-enwe mgbe ụfọdụ adịghị ọcha na-eme ka mmiri na-agba mmiri, nke na-eme ka mmiri ndị a siri ike ihicha.Ọ dị mkpa iji flocculant mee ka mmiri doo anya iji mezuo ọkọlọtọ nkwụsị.Maka flocculant a, anyị na-akwadopolyacrylamide (PAM).

Polyacrylamide bụ polymer na-agbaze mmiri.Ya molekụla yinye nwere pola iche iche, nke nwere ike adsorb ahụ kwụsịtụrụ na ngwọta na agglomerate ahụ na-etolite ibu flocs.Nnukwu flocs ndị a kpụrụ nwere ike mee ka mmiri ozuzo nke irighiri ihe kwụsịtụrụ ma mee ka mmetụta nke nkọwa nkọwa dị ngwa ngwa.E jiri ya tụnyere ọgwụgwọ mmiri mkpofu nkịtị, ọgwụgwọ mmiri ọgwụ kemịkal dị mgbagwoju anya.N'ime usoro ọgwụgwọ mmiri ọgwụ kemịkal, a chọrọ ihe dị iche iche dị ka flocculants, coagulant, na decolorizers.N'ime ha, flocculant a na-ejikarị eme ihe bụ nonionic polyacrylamide.

Usoro mmepe nke polyacrylamide

1. The polyacrylamide molekul yinye nwere pola iche iche, nke nwere ike banye irighiri kwụsịtụrụ na mmiri na àkwà mmiri n'etiti ahụ na-etolite ibu flocs.

2. Polyacrylamide na-abụghị ionic nwere ike mee ka mmiri ozuzo nke ihe nkwụsịtụ kwụsịlata site n'ịmepụta nnukwu flocs, si otú a na-eme ka nkọwa nke ngwọta dị ngwa ma na-akwalite mmetụta nzacha.

3. N'ime ngwaahịa flocculant niile, polyacrylamide na-abụghị ionic nwere mmetụta dị mma n'ịgwọ mmiri mkpofu acidic, na mmiri mkpofu kemịkal na-abụkarị acidic.Ya mere, polyacrylamide na-abụghị ionic nwere uru pụrụ iche na yaọgwụgwọ mmiri mkpofu mmiri ọgwụ.

4. Enwere ike iji coagulant jikọtara ya na nnu inorganic dị ka polyaluminum, polyiron na ndị ọzọ inorganic flocculants, na mmetụta dị mma.Ọ bụ kpọmkwem n'ihi njirimara nke polyacrylamide na-abụghị ionic na ọ nwere uru doro anya na ọgwụgwọ mmiri mmiri na-ekpo ọkụ.

Anyị na-enye PAM dị elu maka ntinye aka mbụ nke ụlọ ọrụ mmepụta ihe, ka i wee nweta PAM dị ọnụ ahịa na ahụmahụ na-eju afọ mgbe ịre ahịa.
