Indlela kunye nokusetyenziswa kwePolyDADMAC kunyango lwamanzi

I-Polydiallyldimethylammonium chloride(iPolyDADMAC) yi-flocculant ye-cationic polymer esetyenziswa kakhulu kwaye idlala indima ebalulekileyo kwicandelo lokunyanga amanzi. I-PDADMAC idla ngokusetyenziswa njenge-flocculant kwaye ngamanye amaxesha ixutywa ne-algaecides. Eli nqaku liza kuchaza iingenelo kunye nexabiso lokusetyenziswa kwePolyDADMAC kwiinkalo zendlela esebenza ngayo, iimeko zokusetyenziswa kunye namaqhinga athile okuphucula ukusebenza kakuhle konyango lwamanzi.

Iimpawu ezisisiseko zePolyDADMAC

I-PolyDADMAC yi-polymer ephezulu yeemolekyuli enenani elikhulu lamaqela e-cationic kwisakhiwo sayo seemolekyuli, enokuthi ifunxe ngokufanelekileyo ii-particles ezixhonyiweyo kunye nee-colloids emanzini. Iimpawu zayo eziphambili ziquka:

1. Ukuqina okuqinileyo: Inganciphisa ngokukhawuleza amasuntswana axhonyiweyo atshajwe kakubi emanzini.

2. Ukunyibilika kwamanzi okulungileyo: Kulula ukuyinyibilikisa emanzini kwaye ilungele ukusetyenziswa kwindawo leyo.

3. Uzinzo lweekhemikhali: Ingagcina ukusebenza kwe-flocculation esebenza kakuhle kakhulu kwiindidi ezahlukeneyo ze-pH, indawo yokuxovula kunye nendawo yokucheba ngoomatshini ephezulu. I-PDADMAC inokumelana okukhulu ne-chlorine.

4. Ubuthi obuphantsi: Ihlangabezana nemigangatho yokhuseleko lokusingqongileyo kwaye ifanelekile ekucoceni amanzi okusela.

Indlela yokusebenza kwePolyDADMAC kunyango lwamanzi

Iyaphazamisa amasuntswana axhonyiweyo kunye nezinto ezixutyiweyo zamanzi ezitshajiswa kakubi emanzini kwaye iyazinyibilikisa ngokusebenzisa umbane kunye nokudibanisa i-adsorption. Inefuthe elibalulekileyo ekuguquleni umbala, kunye nokususa izinto eziphilayo.

I-PolyDADMACiphucula ukusebenza kakuhle kokucocwa kwamanzi ngokusebenzisa ezi ndlela zilandelayo:

1. Ukungaguquguquki kwentlawulo

Iinxalenye ezixhonyiweyo kunye nee-colloids emanzini zihlala zinee-charges ezingezizo, nto leyo ebangela ukurhawuzelelwa phakathi kwee-particles kwaye yenza kube nzima ukuzinza. Amaqela e-cationic e-PolyDADMAC anokukhawuleza anciphise ii-charges ezingezizo, anciphise ukurhawuzelelwa kwe-electrostatic phakathi kwee-particles, kwaye akhuthaze ukujiya kwee-particles.

2. Isiphumo sokuqhawula

Isakhiwo semolekyuli esinomgca omde sePolyDADMAC esinobukrakra obuphezulu siyenza ikwazi ukwenza "ibhulorho" phakathi kwamasuntswana amaninzi, ihlanganise amasuntswana amancinci abe ziiflocs ezinkulu, ngaloo ndlela iphucula ukusebenza kakuhle kwe-sedimentation.

3. Ukuqinisa isiphumo sokubamba i-net

I-PolyDADMAC inokuqinisa "isakhiwo se-net" esenziwe yi-inorganic coagulant ekunyangweni kwamanzi ukuze ibambe ngokufanelekileyo izinto ezincinci ezixhonyiweyo, ingakumbi kwiindawo ezinamanzi amaninzi okanye amanzi angcoliswe kakhulu.

Iimeko zokusetyenziswa kwePolyDADMAC

1. Unyango lwamanzi okusela

I-PolyDADMAC isetyenziswa njenge-flocculant ukususa ukudumba, amasuntswana axhonyiweyo kunye nezinto eziphilayo emanzini okusela. Kwangaxeshanye, ngenxa yokuba inetyhefu ephantsi kunye neempawu zokukhusela okusingqongileyo, inokuhlangabezana nemigangatho yokhuseleko lwamanzi okusela.

2. Unyango lwamanzi amdaka

Kwinkqubo yokucoca amanzi amdaka kamasipala nakwimizi-mveliso, iPolyDADMAC idla ngokusetyenziswa ukuphucula ukusebenza kokukhupha amanzi ngodaka, ukunciphisa umswakama wekhekhe lodaka, kunye nokunciphisa kakhulu iindleko zokusebenza.

3. Ukucoca amanzi kwimizi-mveliso

Kwimizi-mveliso yamandla, i-petrochemical kunye neminye imimandla, i-PolyDADMAC isetyenziselwa ukucoca amanzi emizi-mveliso afana namanzi okupholisa kunye namanzi ebhoyila ukunciphisa umngcipheko wokukhula kunye nokugqwala.

4. Ushishino lokwenza amaphepha kunye nelaphu

I-PolyDADMAC isetyenziswa njengoncedo lokugcina nokucoca ukuphucula izinga lokugcina iifayibha kunye nezizalisi kwinkqubo yokwenza iphepha, ngelixa kunciphisa umxholo wezinto ezixhonyiweyo emanzini amdaka.

Amaqhinga okuphucula ukusebenza kakuhle kokunyanga amanzi ngePolyDADMAC

1. Ukuphucula ulawulo lwedosi

Umlinganiselo wePolyDADMAC unxulumene ngokusondeleyo noxinzelelo, ukusasazwa kobungakanani bamasuntswana kunye neempawu zongcoliseko lwamasuntswana axhonyiweyo emanzini. Ukuphucula umthamo ngokuvavanya iibhotile kunokwandisa isiphumo sawo sokuqubha ngelixa kuthintelwa umthamo ogqithisileyo okhokelela ekwandeni kweendleko okanye ungcoliseko lwamanzi lwesibini.

2. Isiphumo sokusebenzisana kunye nee-flocculants ezingaphiliyo

Ukusetyenziswa kwePolyDADMAC kunye nee-flocculants ezingaphiliyo (ezifana ne-polyaluminium chloride kunye ne-aluminium sulfate) kunokunyusa kakhulu isiphumo se-flocculation. Emva kokuba iPolyDADMAC ingasebenzisi amandla omphezulu wee-particles, ii-flocculants ezingaphiliyo zenza ii-floc ezinkulu ngokufaka i-adsorption kunye ne-sedimentation.

3. Ukuphucula inqanaba lokusebenza ngokuzenzekelayo kweenkqubo zokunyanga amanzi

Ngoncedo lweenkqubo zokulawula ezenzekelayo, ukujonga ngexesha langempela kunye nokulungiswa kwedosi yePolyDADMAC kunokufezekiswa ukuze kujongwane notshintsho ekusebenzeni kakuhle konyango olubangelwa kukuguquguquka komgangatho wamanzi.

4. Lungiselela iimeko zokuxukuxa

Emva kokongeza iPolyDADMAC, ukuqina okufanelekileyo kunye nexesha elifanelekileyo kunokuphucula ukusasazeka kwayo kunye nokusebenza kakuhle kwe-flocculation. Ukuxuba okugqithisileyo kunokubangela ukuba ii-floc ziqhekeke, ngelixa ukuxuba okunganelanga kuya kunciphisa isiphumo sokuxuba.

5. Lungisa ixabiso le-pH

I-PolyDADMAC isebenza kakuhle phantsi kweemeko ze-alkaline ezingathathi cala ukuya kwezibuthathaka. Xa kunyangwa amanzi ane-asidi eninzi okanye ane-alkaline eninzi, ukulungisa ixabiso le-pH lomzimba wamanzi kunokuphucula kakhulu isiphumo sawo sokuqunjelwa.

Iingenelo zePolyDADMAC

1. Ukusebenza kakuhle okuphezulu: Ukwakheka ngokukhawuleza kwee-flocs ukuphucula ukusebenza kakuhle kokwahlulwa kolwelo oluqinileyo.

2. Uluhlu olubanzi lwezicelo: Isebenza kwiimpawu ezahlukeneyo zamanzi, ingakumbi amanzi anokufuma okuphezulu kunye nomxholo ophezulu wendalo.
