Usoro na itinye PolyDADMAC na ọgwụgwọ mmiri

Polydiallyldimethylammonium chloride(PolyDADMAC) bụ cationic polymer flocculant nke a na-ejikarị eme ihe ma na-arụ ọrụ dị mkpa na ngalaba ọgwụgwọ mmiri. A na-ejikarị PDADMAC eme ihe dị ka flocculant na mgbe ụfọdụ a na-ejikọta ya na algaecides. Isiokwu a ga-akọwapụta uru na uru ngwa bara uru nke PolyDADMAC site na akụkụ nke usoro ya, ihe omume ngwa na atụmatụ akọwapụtara maka imeziwanye ọgwụgwọ mmiri.

Njiri mara nke PolyDADMAC

PolyDADMAC bụ polymer molekụla dị elu nke nwere ọnụ ọgụgụ dị ukwuu nke cationic dị iche iche na usoro ihe omimi ya, nke nwere ike ịgbasa ihe ndị kwụsịtụrụ na colloid n'ime mmiri nke ọma. Isi njirimara ya gụnyere:

1. Ike cationicity: Ọ nwere ike ngwa ngwa neutralize ọjọọ ebubo kwụsịtụrụ na mmiri.

2. Ezigbo solubility mmiri: Ọ dị mfe igbari na mmiri ma dị mma maka ngwa saịtị.

3. Nkwụsi ike nke kemịkal: Ọ nwere ike ịnọgide na-arụ ọrụ flocculation dị elu na ọkwa pH dị iche iche, gburugburu ebe obibi oxidizing na gburugburu ebe obibi dị elu. PDADMAC nwere nguzogide chlorine siri ike.

4. Nsi dị ala: Ọ na-agbaso ụkpụrụ nchebe gburugburu ebe obibi ma dị mma maka ọgwụgwọ mmiri ọṅụṅụ.

Usoro omume nke PolyDADMAC na ọgwụgwọ mmiri

Ọ na-emebi irighiri ihe kwụsịtụrụ yana ebubo ihe ngwọta mmiri na-adịghị mma na mmiri ma na-ebugharị ha site na neutralization eletriki na mgbasa ozi mgbasa ozi. Ọ nwere mmetụta dị ịrịba ama na decolorization, na iwepụ ihe ndị dị ndụ.

PolyDADMACna-eme ka ọgwụgwọ mmiri dịkwuo mma site na usoro ndị a:

1. Charge neutralization

Ụmụ irighiri ihe akwụsịlata na colloid n'ime mmiri na-ebukarị ebubo na-adịghị mma, nke na-ebute mmekọrita n'etiti ụmụ irighiri ihe na-eme ka o sie ike idozi. Otu cationic nke PolyDADMAC nwere ike wepụ ngwa ngwa ebubo na-adịghị mma, belata nhụsianya electrostatic n'etiti ụmụ irighiri ihe, ma kwalite urughuru coagulation.

2. Mkpokọta mmetụta

Usoro ihe omimi nke ogologo ogologo nke PolyDADMAC viscosity dị elu na-enyere ya aka ịmepụta "àkwà mmiri" n'etiti ọtụtụ irighiri ihe, na-ejikọta obere ihe n'ime nnukwu flocs, si otú ahụ na-eme ka arụmọrụ sedimentation dịkwuo mma.

3. Na-eme ka mmetụta ntanetị dị ike

PolyDADMAC nwere ike iwusi “ụkpụrụ netwọọkụ” nke inorganic coagulant hibere n'ime ọgwụgwọ mmiri iji weghara ihe dị mma kwụsịtụrụ nke ọma, ọkachasị n'oke mmiri dị elu ma ọ bụ mmiri emetọru nke ukwuu.

Ihe ndapụta ngwa nke PolyDADMAC

1. Ọgwụgwọ mmiri ọṅụṅụ

A na-eji PolyDADMAC dị ka flocculant wepụ turbidity, ahụ kwụsịtụrụ na organic okwu na mmiri ọṅụṅụ. N'otu oge ahụ, n'ihi obere nsí ya na njirimara nchebe gburugburu ebe obibi, ọ nwere ike izute ụkpụrụ nchekwa nchekwa mmiri ọṅụṅụ.

2. Ọgwụgwọ mmiri mkpofu

N'ime ọgwụgwọ mmiri mkpofu nke ime obodo na ụlọ ọrụ mmepụta ihe, a na-ejikarị PolyDADMAC emeziwanye arụmọrụ sludge dewatering, belata ọdịnaya mmiri nke achicha apịtị, ma belata ụgwọ ọrụ.

3. Ụlọ ọrụ mmepụta ihe dị ọcha

N'ime ike, petrochemical na ụlọ ọrụ ndị ọzọ, a na-eji PolyDADMAC mee ka mmiri dị ọcha dị ka mmiri jụrụ oyi na mmiri ọkụ iji belata ihe egwu na corrosion.

4. Ime akwụkwọ na ụlọ ọrụ textile

A na-eji PolyDADMAC mee ihe dị ka ihe ndochi na nzacha enyemaka iji melite ọnụego njide nke eriri na ihe ndochi na usoro nhazi akwụkwọ, na-ebelata ọdịnaya nke ihe kwụsịtụrụ na mmiri mkpofu.

Atụmatụ maka imeziwanye ọgwụgwọ mmiri na PolyDADMAC

1. Na-ebuli njikwa usoro onunu ogwu

Usoro onunu ogwu nke PolyDADMAC nwere njikọ chiri anya na mkpokọta, nkesa nha nha yana njirimara mmetọ nke ihe kwụsịtụrụ na mmiri. Ịkwalite usoro onunu ogwu site na nnwale ite nwere ike ịbawanye mmetụta flocculation ya ma na-ezere oke onunu ogwu nke na-eduga n'ịba ụba ego ma ọ bụ mmetọ mmiri nke abụọ.

2. Synergistic mmetụta na inorganic flocculants

Iji PolyDADMAC yana ngwakọta inorganic flocculants (dị ka polyaluminium chloride na aluminom sulfate) nwere ike ịkwalite mmetụta flocculation nke ukwuu. Mgbe PolyDADMAC kwụsịrị ụgwọ elu nke ụmụ irighiri ihe ahụ, flocculants inorganic na-etolite flocs buru ibu site na mgbasa ozi na sedimentation.

3. Meziwanye ọkwa akpaaka nke usoro ọgwụgwọ mmiri

Site n'enyemaka nke sistemu njikwa akpaghị aka, enwere ike nweta nleba anya na ngbanwe nke usoro ọgwụgwọ PolyDADMAC iji nagide mgbanwe na arụmọrụ ọgwụgwọ nke ngbanwe ogo mmiri kpatara.

4. Kwalite ọnọdụ mkpali

Mgbe ịgbakwunye PolyDADMAC, kwesịrị ekwesị ịkpali ike na oge nwere ike welie ya dispersibility na flocculation arụmọrụ. Nnukwu mkpali nwere ike ime ka flocs gbajie, ebe ịkpali ezughị ezu ga-ebelata mmetụta ngwakọta.

5. Gbanwee uru pH

PolyDADMAC na-arụ ọrụ kacha mma n'okpuru nnọpụiche na ọnọdụ alkaline adịghị ike. Mgbe ị na-agwọ oke acidic ma ọ bụ mmiri alkaline nke ukwuu, imezi uru pH nke ahụ mmiri nwere ike melite mmetụta flocculation ya nke ọma.

Uru nke PolyDADMAC

1. Ịrụ ọrụ dị elu: Ịmepụta ngwa ngwa nke flocs iji melite arụmọrụ nkewa siri ike-mmiri.

2. Ngwa dị ukwuu: Ọdabara na àgwà mmiri dị iche iche, karịsịa mmiri nwere nnukwu turbidity na nnukwu ọdịnaya organic.

3. Nchekwa gburugburu ebe obibi: Obere toxicity na biodegradability, kwekọrọ na ihe nchekwa gburugburu ebe obibi chọrọ.

Dị ka a ukwuu ịrụ ọrụ nke ọmaflocculant, PolyDADMAC nwere uru ngwa dị ịrịba ama na mpaghara ọgwụgwọ mmiri n'ihi ike cationicity ya, ezigbo mmiri solubility na ngwa ngwa. Site na njikarịcha usoro ezi uche dị na ya na atụmatụ ọrụ, a pụrụ imeziwanye arụmọrụ ọgwụgwọ ya na nchacha nke mmiri ọṅụṅụ, nsị mmiri na mmiri mmepụta ihe.
