Indlela kanye nokusetshenziswa kwe-PolyDADMAC ekwelapheni amanzi

I-Polydiallyldimethylammonium chloride(i-PolyDADMAC) iyi-flocculant ye-cationic polymer esetshenziswa kabanzi futhi idlala indima ebalulekile emkhakheni wokwelashwa kwamanzi. I-PDADMAC ivame ukusetshenziswa njenge-flocculant futhi ngezinye izikhathi ihlanganiswa nama-algaecides. Lesi sihloko sizochaza ngezinzuzo kanye nenani lokusetshenziswa okusebenzayo kwe-PolyDADMAC kusukela ezicini zendlela esebenza ngayo, izimo zokusetshenziswa kanye namasu athile okuthuthukisa ukusebenza kahle kokwelashwa kwamanzi.

Izici eziyisisekelo ze-PolyDADMAC

I-PolyDADMAC iyi-polymer ephezulu yama-molecule enenani elikhulu lamaqembu e-cationic esakhiweni sayo sama-molecule, engamunca ngempumelelo izinhlayiya ezilengisiwe nama-colloid emanzini. Izici zayo eziyinhloko zifaka:

1. Ukuqina okuqinile: Ingasusa ngokushesha izinhlayiya ezilengayo ezishajelwe kabi emanzini.

2. Ukuncibilika kwamanzi okuhle: Kulula ukuncibilika emanzini futhi kulula ukuyisebenzisa endaweni.

3. Ukuqina kwamakhemikhali: Ingagcina ukusebenza kahle kwe-flocculation emazingeni ahlukene e-pH, indawo yokuxova kanye nendawo yokusika ephezulu yomshini. I-PDADMAC inokumelana okuqinile kwe-chlorine.

4. Ubuthi obuphansi: Ihlangabezana nezindinganiso zokuvikela imvelo futhi ifanelekela ukwelashwa kwamanzi okuphuza.

Indlela yokusebenza kwe-PolyDADMAC ekwelapheni amanzi

Iphazamisa izinhlayiya ezilengayo kanye nezinto ezixazululwa ngamanzi ezishajelwe kabi emanzini futhi izicwilise ngokusebenzisa ukuncishiswa kukagesi kanye nokubopha i-adsorption. Inemiphumela ebalulekile ekushintsheni umbala, kanye nokususwa kwezinto eziphilayo.

I-PolyDADMACkuthuthukisa ukusebenza kahle kokwelashwa kwamanzi ngezindlela ezilandelayo:

1. Ukunciphisa ukushaja

Izinhlayiya ezilengayo kanye nama-colloid emanzini ngokuvamile athwala amacala amabi, okubangela ukuxokozela phakathi kwezinhlayiya futhi kwenza kube nzima ukuzinza. Amaqembu e-cationic e-PolyDADMAC anganciphisa ngokushesha amacala amabi, anciphise ukuxokozela kwe-electrostatic phakathi kwezinhlayiya, futhi akhuthaze ukujiya kwezinhlayiya.

2. Umphumela wokuvala

Isakhiwo sama-molecule eside se-PolyDADMAC esinobuthi obukhulu siyenza ikwazi ukwakha “ibhuloho” phakathi kwezinhlayiya eziningi, ihlanganise izinhlayiya ezincane zibe ama-floc amakhulu, ngaleyo ndlela ithuthukise ukusebenza kahle kwe-sedimentation.

3. Ukuqinisa umphumela wokubamba i-net

I-PolyDADMAC ingaqinisa "isakhiwo senethi" esakhiwe yi-coagulant engaphili ekuphathweni kwamanzi ukuze ibambe kahle izinto ezincane ezilengayo, ikakhulukazi emanzini anomswakama omningi noma angcoliswe kakhulu.

Izimo zokusetshenziswa kwe-PolyDADMAC

1. Ukwelashwa ngamanzi okuphuza

I-PolyDADMAC isetshenziswa njenge-flocculant ukususa ukungcola, izinhlayiya ezilengayo kanye nezinto eziphilayo emanzini okuphuza. Ngesikhathi esifanayo, ngenxa yobuthi bayo obuphansi kanye nezici zokuvikela imvelo, ingahlangabezana nezindinganiso zokuphepha emanzini okuphuza.

2. Ukwelashwa kwamanzi angcolile

Ekuphathweni kwamanzi amdaka kamasipala kanye nezimboni, i-PolyDADMAC ivame ukusetshenziselwa ukuthuthukisa ukusebenza kokukhipha amanzi odakeni, ukunciphisa okuqukethwe komswakama wekhekhe lodaka, kanye nokunciphisa kakhulu izindleko zokusebenza.

3. Ukuhlanzwa kwamanzi ezimbonini

Ezimbonini zamandla, ze-petrochemical kanye nezinye, i-PolyDADMAC isetshenziselwa ukuhlanza amanzi ezimbonini njengamanzi okupholisa kanye namanzi abilayo ukuze kuncishiswe ukukhuhla kanye nezingozi zokugqwala.

4. Imboni yokwenza amaphepha kanye nezindwangu

I-PolyDADMAC isetshenziswa njengosizo lokugcina nokuhlunga ukuthuthukisa izinga lokugcina imicu kanye nezigcwalisi enkambisweni yokwenza amaphepha, ngenkathi kunciphisa okuqukethwe kwezinto ezilengisiwe emanzini amdaka.

Amasu okuthuthukisa ukusebenza kahle kokwelashwa kwamanzi nge-PolyDADMAC

1. Ukuthuthukisa ukulawula umthamo

Umthamo we-PolyDADMAC uhlobene eduze nokuhlushwa, ukusatshalaliswa kosayizi wezinhlayiya kanye nezici zokungcola kwezinhlayiya ezilengisiwe emanzini. Ukwenza ngcono umthamo ngokuhlolwa kwembiza kungakhulisa umphumela wayo wokugobhoza ngenkathi kugwenywa umthamo oweqile oholela ekwandeni kwezindleko noma ekungcolisweni kwamanzi kwesibili.

2. Umphumela wokubambisana nama-flocculant angaphili

Ukusetshenziswa kwe-PolyDADMAC kuhlanganiswe nama-flocculant angaphili (njenge-polyaluminium chloride kanye ne-aluminium sulfate) kungathuthukisa kakhulu umphumela we-flocculation. Ngemva kokuthi i-PolyDADMAC iqede ukushaja okuphezulu kwezinhlayiya, ama-flocculant angaphili aqhubeka nokwakha ama-floc amakhulu ngokumuncwa kanye nokuthungwa.

3. Thuthukisa izinga lokuzenzakalela kwezinqubo zokwelashwa kwamanzi

Ngosizo lwezinhlelo zokulawula ezenzakalelayo, ukuqapha kanye nokulungiswa kwesikhathi sangempela kwesilinganiso se-PolyDADMAC kungafinyelelwa ukuze kubhekane nezinguquko ekusebenzeni kahle kokwelashwa okubangelwa ukushintshashintsha kwekhwalithi yamanzi.

4. Lungiselela izimo zokuxubha

Ngemva kokufaka i-PolyDADMAC, ukuqina okufanele kokuxubha kanye nesikhathi kungathuthukisa ukuhlakazeka kwayo kanye nokusebenza kahle kokuxubha. Ukuxubha ngokweqile kungabangela ukuthi ama-floc aphuke, kanti ukuxubha okunganele kuzonciphisa umphumela wokuxuba.

5. Lungisa inani le-pH

I-PolyDADMAC isebenza kahle kakhulu ngaphansi kwezimo ezingathathi hlangothi kuya kwezingaqinile ze-alkaline. Lapho welapha amanzi ane-acidic ephezulu noma ane-alkaline ephezulu, ukulungisa inani le-pH lomzimba wamanzi kungathuthukisa kakhulu umphumela wawo we-flocculation.

Izinzuzo ze-PolyDADMAC

1. Ukusebenza kahle okuphezulu: Ukwakheka okusheshayo kwama-floc ukuthuthukisa ukusebenza kahle kokuhlukaniswa koketshezi oluqinile.

2. Uhla olubanzi lwezicelo: Isebenza ezimfanelweni zamanzi ezahlukahlukene, ikakhulukazi amanzi anomswakama ophezulu kanye nokuqukethwe okuphezulu kwezinto eziphilayo.

3. Ukuvikelwa kwemvelo: Ubuthi obuphansi kanye nokubola kwezinto eziphilayo, ngokuvumelana nezidingo zokuvikela imvelo.

Njengomsebenzi osebenza kahle kakhului-flocculant, I-PolyDADMAC inezinzuzo ezibalulekile zokusetshenziswa emkhakheni wokwelashwa kwamanzi ngenxa yokuqina kwayo okukhulu, ukuncibilika kwamanzi okuhle kanye nokusebenza okubanzi. Ngokusebenzisa amasu okuthuthukisa inqubo anengqondo kanye nokusebenza, ukusebenza kwayo kahle kokwelashwa ekuhlanzweni kwamanzi okuphuza, indle kanye namanzi ezimboni kungathuthukiswa kakhulu.
