Inkqubo kunye nokusetyenziswa kwePolyDADMAC kunyango lwamanzi

Polydiallyldimethylammonium chloride(I-PolyDADMAC) isetyenziswa ngokubanzi i-cationic polymer flocculant kwaye idlala indima ebalulekileyo kwintsimi yonyango lwamanzi. I-PDADMAC iqhele ukusetyenziswa njenge-flocculant kwaye ngamanye amaxesha idityaniswe ne-algaecides. Eli nqaku liza kucacisa malunga neenzuzo kunye nexabiso elisebenzayo le-PolyDADMAC kwiinkalo zendlela yokusebenza kwayo, iimeko zesicelo kunye nezicwangciso ezithile zokuphucula ukucocwa kwamanzi.

Iimpawu eziphambili zePolyDADMAC

I-PolyDADMAC i-polymer ye-molecular ephezulu kunye nenani elikhulu lamaqela e-cationic kwisakhiwo sayo se-molecular, enokuthi ibhengeze ngokufanelekileyo iinqununu ezimisiweyo kunye ne-colloids emanzini. Iimpawu zayo eziphambili ziquka:

1. I-cationicity eyomeleleyo: Inokunciphisa ngokukhawuleza amasuntswana amisiweyo ahlawuliswa kakubi emanzini.

2. Ukunyibilika kakuhle kwamanzi: Kulula ukunyibilika emanzini kwaye kulungele ukusetyenziswa kwendawo.

3. Uzinzo lwekhemikhali: Inokugcina ukusebenza kakuhle kwe-flocculation kwiindidi ezahlukeneyo ze-pH, indawo ene-oxidizing kunye nemekobume ephezulu yokucheba. I-PDDMAC inokumelana neklorini eyomeleleyo.

4. Ubuthi obuphantsi: Ihlangabezana nemigangatho yokukhuselwa kokusingqongileyo kwaye ifanelekile kunyango lwamanzi okusela.

Inkqubo yesenzo sePolyDADMAC kunyango lwamanzi

Iphazamisa amasuntswana amisiweyo kwaye ihlawuliswe kakubi izinto zesisombululo se-aqueous emanzini kwaye i-flocculates ngokusebenzisa i-neutralization yombane kunye ne-adsorption bridging. Ineempembelelo ezibalulekileyo kwi-decolorization, kunye nokususwa kwezinto eziphilayo.

PolyDADMACiphucula impumelelo yokucocwa kwamanzi ngezi ndlela zilandelayo:

1. Intlawulo yokungathathi hlangothi

Amasuntswana amisiweyo kunye ne-colloids emanzini ngokuqhelekileyo athwala iintlawulo ezingalunganga, ezibangela ukunyathelana phakathi kwamaqhekeza kwaye kwenza kube nzima ukuzinza. Amaqela e-cationic e-PolyDADMAC anokukhawuleza ukunciphisa iintlawulo ezingalunganga, ukunciphisa ukunyanzeliswa kwe-electrostatic phakathi kwamaqhekeza, kunye nokukhuthaza ukudibanisa i-particle coagulation.

2. Isiphumo sokuvala

Isakhiwo se-molecular chain ende ye-high-viscosity PolyDADMAC yenza ukuba yenze "ibhuloho" phakathi kweengqungquthela ezininzi, ukudibanisa amaqhekeza amancinci kwiifloksi ezinkulu, ngaloo ndlela kuphuculwe ukusebenza kakuhle kwe-sedimentation.

3. Ukomeleza i-net capture effect

I-PolyDADMAC inokomeleza "isakhiwo somnatha" esenziwe yi-inorganic coagulant kunyango lwamanzi ukuze ibambe ngokufanelekileyo into emisiweyo, ngakumbi kwi-turbidity ephezulu okanye amanzi angcoliseke kakhulu.

Iimeko zokusetyenziswa kwePolyDADMAC

1. Ukucoca amanzi okusela

I-PolyDADMAC isetyenziswa njenge-flocculant ukususa i-turbidity, amasuntswana amisiweyo kunye ne-organic matter kumanzi okusela. Ngelo xesha, ngenxa yobutyhefu obuphantsi kunye neempawu zokukhuselwa kwendalo, inokuhlangabezana nemigangatho yokhuseleko lwamanzi okusela.

2. Ukucocwa kwamanzi amdaka

Kumanzi amdaka kamasipala nakwimizi-mveliso, i-PolyDADMAC isoloko isetyenziselwa ukuphucula ukusebenza kwe-sludge dewatering, ukunciphisa ukufuma kwekhekhe lodaka, kunye nokunciphisa kakhulu iindleko zokusebenza.

3. Ukucocwa kwamanzi kwimizi-mveliso

Kumandla, i-petrochemical kunye namanye amashishini, i-PolyDADMAC isetyenziselwa ukuhlanjululwa kwamanzi amashishini afana namanzi okupholisa kunye namanzi ebhoyila ukunciphisa umngcipheko kunye nokubola.

4. Ukwenziwa kwamaphepha kunye neshishini lempahla yamalaphu

I-PolyDADMAC isetyenziselwa ukugcinwa kunye nokuncedisa ukucoca ukuphucula izinga lokugcinwa kweefayili kunye nokuzalisa inkqubo yokwenza iphepha, ngelixa unciphisa umxholo wezinto ezimisiweyo kumanzi amdaka.

Amaqhinga okuphucula ukucocwa kwamanzi ngePolyDADMAC

1. Ukuphucula ulawulo lwedosi

I-dosage ye-PolyDADMAC inxulumene ngokusondeleyo noxinaniso, ukusabalalisa ubungakanani be-particle size kunye neempawu ezingcolileyo zamasuntswana amisiweyo emanzini. Ukuphucula idosi ngovavanyo lwejagi kunokwandisa isiphumo sayo sokushukuma ngelixa unqanda idosi ethe kratya ekhokelela kwiindleko ezongezelelekileyo okanye ungcoliseko lwamanzi lwesibini.

2. Impembelelo ye-Synergistic kunye ne-inorganic flocculants

Ukusetyenziswa kwePolyDADMAC ngokudibanisa ne-inorganic flocculants (efana ne-polyaluminium chloride kunye ne-aluminium sulfate) inokunyusa kakhulu umphumo we-flocculation. Emva kokuba i-PolyDADMAC ingathathi hlangothi umrhumo womphezulu wamasuntswana, i-inorganic flocculants iqhubela phambili ukwenza iiflocs ezinkulu ngokusebenzisa i-adsorption kunye ne-sedimentation.

3. Ukuphucula umgangatho wokuzenzekelayo weenkqubo zokucocwa kwamanzi

Ngoncedo lweenkqubo zokulawula ngokuzenzekelayo, ukubeka iliso ngexesha langempela kunye nohlengahlengiso lwe-PolyDADMAC dosage inokufezekiswa ukujamelana neenguqu ekusebenzeni kakuhle kwonyango okubangelwa ukuguquguquka komgangatho wamanzi.

4. Lungiselela iimeko ezishukumisayo

Emva kokongeza i-PolyDADMAC, ukuqina okufanelekileyo kunye nexesha kunokunyusa ukusasazeka kwayo kunye nokusebenza kakuhle kokuhamba. Ukuvuselela okugqithisileyo kunokubangela ukuba i-flocs iphuke, ngelixa ukunyanzeliswa okunganeleyo kuya kunciphisa umphumo wokuxuba.

5. Lungisa ixabiso le-pH

I-PolyDADMAC isebenza kakuhle phantsi kokungathathi hlangothi kwiimeko ezibuthathaka zealkaline. Xa unyanga amanzi ane-asidi ephezulu okanye ane-alkaline kakhulu, ukulungelelanisa ixabiso le-pH lomzimba wamanzi kunokuphucula kakhulu isiphumo salo se-flocculation.

Izinto eziluncedo zePolyDADMAC

1. Ukusebenza okuphezulu: Ukubunjwa okukhawulezayo kweeflocs ukuphucula ukwahlula okuqinileyo-ulwelo olusebenzayo.

2. Uluhlu olubanzi lwezicelo: Isebenza kwiimpawu zamanzi ezohlukeneyo, ngakumbi amanzi ane-turbidity ephezulu kunye nomxholo ophezulu we-organic.

3. Ukhuseleko lokusingqongileyo: Ubuthi obuphantsi kunye nokonakala kwezinto eziphilayo, ngokuhambelana neemfuno zokhuseleko lokusingqongileyo.

Njengomsebenzi ophezulu kakhuluflocculant, I-PolyDADMAC ineenzuzo ezibalulekileyo zesicelo kwintsimi yonyango lwamanzi ngenxa ye-cationicity eqinile, ukunyibilika kwamanzi okulungileyo kunye nokusebenziseka okubanzi. Ngokusetyenziswa kwenkqubo efanelekileyo kunye nezicwangciso zokusebenza, ukusebenza kakuhle konyango ekucocweni kwamanzi okusela, ugutyulo kunye namanzi oshishino kunokuphuculwa ngakumbi.
