Izinzuzo zokusebenza kahle kwe-polyaluminum chloride ekwelashweni kwamanzi amdaka

Ngokusheshisa kwezimboni, ukuphuma kwendle sekuyinkinga enkulu ekuvikelweni kwemvelo yemvelo. Umnyombo wokwelashwa kwendle ulele ekukhetheni nasekusetshenzisweni kweAma-Flocculatantsinqubo yokuhlanza. Eminyakeni yamuva nje, i-polyaluminum chloride (PAC), njenge-flocculant ebalulekile, kancane kancane ibe "umkhiqizo wenkanyezi" embonini yezokuthuthwa kwendle ngenxa yokusebenza kwayo okuhle kanye namathemba wohlelo lokusebenza oluningi.

I-Polyaluminum Chloride iyingxenye ye-Inormer polymer enomphumela onamandla we-floccation. Itholakala ngokusabela kwe-polymerization ye-aluminium chloride ne-aluminium hydroxide ngaphansi kwezimo ezithile. Uma kuqhathaniswa nama-aluminium we-aluminium usawoti we-flocculants (njenge-aluminium sulfate, i-aluminium salt coagulant, njll.) Ukusebenza kuvelele ikakhulukazi uma kukhulunywa ngekhwalithi yamanzi. Kusetshenziswe kabanzi emikhakheni eminingi efana nokwelashwa kwendle kondle, ukwelashwa kwendle kwezimboni, kanye nokwelashwa kwendle kwasekhaya.

Izinzuzo zokusebenza kahle kwe-polyaluminum chloride

1. Umphumela we-floccation uyamangalisa

I-polyaluminum chloride ephezulu ikwazi ukwakha inamba enkulu yama-flocs amahle emanzini, ngaleyo ndlela ngempumelelo ama-adderbing amise ama-solids, izinto ezi-colloidal kanye nama-microorganisms emanzini. Kungashesha ama-adsorb futhi asuse izinhlayiya ezimisiwe, amafutha, ama-ion wensimbi asindayo nokunye ukungcoliswa kwamanzi. Ikakhulu uma ubhekene nekhwalithi yamanzi eyinkimbinkimbi, umphumela uphakeme kakhulu kunendabuko yendabuko ye-aluminium kasawoti. Ekwelashweni kwendle kwendle, i-polyaluminum chloride ephezulu ingakhuphula ijubane lokuxazulula ithangi ledimentation ngesikhathi esifushane, ngaleyo ndlela linciphise kakhulu umjikelezo wokwelashwa kwendle.

Ibanga le-2.Wide of application

I-Polyaluminium Chloride ephezuluUngazivumelanisa nezimo ezahlukahlukene zekhwalithi yamanzi, kufaka phakathi amanzi aphezulu wokuqina, amanzi okuhambisa indle okuphezulu, amanzi aqukethe izinsimbi ezisindayo, namanzi aphansi okushisa aphansi, okubonisa ukuzivumelanisa nezimo okuqinile. Kungasusa kahle ama-solids amiswe kahle kanye nokungcola emanzini, futhi kungasetshenziswa kabanzi ekwelashweni kwendle emikhakheni ehlukene njengokuphathwa komasipala, imboni, nezimayini. Isibonelo, ekulweni nendle ezifuywayo, amanzi e-pulp mill wastewater, i-metallurgical wastewater, embonini yokudla edonswa amanzi kanye nezinye izimo, i-polyaluminum chloride ephezulu ingathola imiphumela emihle yokwelashwa.

3. Imithamo ephansi, ukusebenza kahle okuphezulu nokulondolozwa kwamandla

I-Polyaluminium Chloride ephezulu yakhelwe ukufeza umthamo omncane kanye nomphumela ongcono we-floccation. Umthamo we-turbidity ephansi ngu-25- 40% we-aluminium sulfate, kanye nomthamo we-turbidity ephezulu yi-10-25% ye-aluminium sulfate. Lokhu akukunciphisi nje izindleko zokusebenzisa amakhemikhali, kepha futhi kunciphisa ukusetshenziswa kwamandla kanye ne-sludge kwinqubo yokwelashwa kwendle. Ngenxa yendawo yayo ephansi ye-aluminium, kunciphisa ukungcoliswa kwesibili kwemizimba yamanzi futhi kunciphisa kakhulu izindleko zokwelashwa kwendle. Ngakho-ke, sekuyithuluzi elibalulekile lokugcina izindleko futhi kuthuthukise ukusebenza kahle ezinhlelweni ezisebenzayo.

4. Imvelo inobungane

Ukusetshenziswa kwe-polyalumininium chloride ephezulu kunomthelela omncane emvelweni nasezinsalweni eziphansi ze-aluminium. Uma kuqhathaniswa namanye amakhemikhali amakhemikhali, i-polyaluminium chloride iphephe futhi inomthelela omncane ku-PH kanye ne-TA ye-affluent, ngakho-ke isidingo samakhemikhali silungiswe. Ikakhulu ekuphathweni kwendle okukhulu kwesendle kanye namaphrojekthi wokuvikela ezemvelo, sekuphenduke ukukhetha okuluhlaza okwenzeka emvelweni.

I-5. Ilungele izinga lokushisa eliphansi kanye nokwelashwa kwamanzi okubucayi okuphezulu

Ukwelashwa kwamanzi ngezikhathi zokushisa okuphansi kuyinselelo evamile. Ikakhulu ebusika obandayo, ukusebenza kwezinto eziningi ze-Flocculants zendabuko kuzoncishiswa kakhulu. Kodwa-ke, i-polyaluminum chloride ephezulu ingaqhubeka nokugcina umphumela ophakeme we-floccation ngaphansi kwezimo zokushisa eziphansi. Ngaphezu kwalokho, lapho i-terbidity yamanzi iphakeme, i-PAC ibuye ikhombisa amakhono okusebenza aqinile futhi ingasusa ngempumelelo izinhlayiya ezimisiwe nezinto eziphilayo emanzini. Ngamanzi ngokungcoliswa kwamafutha asindayo, i-polyaluminum chloride ephezulu nayo inomphumela omuhle kakhulu ohlisayo.

6. Hlela amabanga ahlukene we-PH

I-Polyaluminium Chloride ephezulu inokuguquguquka okuqinile kokushintsha emanzini angenamanzi futhi kungasebenza ngempumelelo ebangeni elibanzi le-PH. Ngokuvamile, i-PAC ingagcina umphumela omuhle we-floccation emanzini nge-lower (acidic) noma inani eliphakeme (alkaline) PH VALUE, elinwebeka ngokusebenza kwalo ngaphansi kwezimo ezahlukahlukene zamanzi. 5.0-9.0 vs 5.5-7.5

7. Thuthukisa ukusebenza kahle kwe-sediment futhi unciphise ivolumu ye-sludge

I-Polyaluminum Chloride ephezulu iyasiza ukusheshisa ukukhokhelwa kwezinhlayiya eziqinile ekukhuculweni kwendle futhi kuthuthukise ukusebenza kahle kwethangi le-sedimentation ngokwenza ngcono ama-flocs. Ngaphezu kwalokho, ngenxa yezinga eliphakeme le-polymerization of polyaluminum chloride, ama-flocs asungulwa athambile futhi axazululwe ngokushesha, ngaleyo ndlela anciphise inani le-sludge elikhiqizwayo. Lokhu kubaluleke kakhulu ukwelashwa okulandelayo kwe-sludge nokulahlwa, futhi kunganciphisa izindleko nobunzima bokwelashwa kwe-sludge.

Izibonelo Zezicelo Zokusebenza Okuphezulu Polyaluminum Chloride ekwelashweni kwamanzi angcolile

1. Ukwelashwa kwendle ngomasipala

Emkhakheni wokwelashwa kwendle kondle, i-polyaluminum chloride ephezulu ingasetshenziswa kabanzi ekunciphiseni nasezindabeni zokwelashwa kwesibili kwezitshalo zamanzi. Ingasusa ngempumelelo ama-solids amiswe ngempumelelo, izinto ezi-colloidal, amagciwane nezinye izinto ezincane zamanzi emanzini, zithuthukise ikhwalithi yamanzi, futhi zinikeze umthombo wamanzi ophakeme wekhwalithi yokwelashwa okulandelayo kwebhayoloji. I-PAC isiphenduke ingenye yezentengiso ezijwayelekile ezitshalweni zokwelashwa kwendle emadolobheni amaningi ekhaya nakwamanye amazwe.

I-2.Ingcurial Wastewater Treatment

Emkhakheni wezokwelashwa kwamanzi ezimboni, i-polyaluminum chloride ephezulu futhi isetshenziswa kabanzi. Inomphumela omuhle wokwelashwa kumanzi angcolile wezimboni kusuka ekushicilelweni nasedaya, emaphaketheni, isikhumba, i-electroplating kanye nezinye izimboni, futhi angasusa ngempumelelo ukungcola okufana nombala, i-cod ne-bod. Isibonelo, kuma-metallurgy, amandla kagesi, imboni yamakhemikhali, ukucubungula ukudla, ukucubungula ukudla kanye nezinye izimboni, i-PAC kungasiza ukususa izinsimbi ezisindayo, amabala owoyela, izinhlayiya ezisokiweyo kanye nokunye ukungcoliswa kwezinye izinhlayiya. Ikakhulu lapho ukwelapha amanzi ase-wastewater, i-PAC ikhombisile ikhono layo elihle kakhulu lokususa uwoyela futhi linganciphisa kakhulu okuqukethwe kawoyela kwemizimba yamanzi.

3. Ukulashwa kwamanzi amamayini

Emkhakheni wezokwelashwa kwamanzi izimayini, i-polyaluminum chloride ephezulu ingasusa ngempumelelo amaminerali, i-sediment kanye nezinye izinto ezimisiwe emanzini, ukuhlinzeka ngokusekelwa kabusha kwamanzi kanye nokuvuselelwa kwemvelo ezindaweni zezimayini. Njengoba ikhwalithi yamanzi ezindlini zezimayini iyinkimbinkimbi futhi imvamisa inemali enkulu yama-solids amisiwe kanye nezinsimbi ezisindayo, ukusebenza kahle kwe-polyaluminum chloride kuvelele ikakhulukazi kulolu hlobo lwekwelashwa kwamanzi amdaka.

Ngenjwayelo,I-Polyaluminum Chloride ephezulu, njenge-flocculant enhle kakhulu yokwelashwa kwendle, kunezinzuzo ezibalulekile zobuchwepheshe nezemvelo. Ikakhulu endabeni yobunzima obuphezulu, ikhwalithi enkulu yamanzi, nokungcoliswa kwamafutha esindayo, kungafinyelela imiphumela emihle kakhulu yokwelashwa.
