Izinzuzo ze-polyaluminum chloride esebenza kahle kakhulu ekwelashweni kwamanzi amdaka

Ngokusheshisa kwezimboni, ukukhishwa kwendle sekuyinkinga enkulu ekuvikelweni kwemvelo emhlabeni jikelele. Umongo wokwelashwa kwendle usekukhetheni nasekusebenziseniama-flocculantenqubweni yokuhlanza. Eminyakeni yamuva nje, i-polyaluminum chloride (PAC) esebenza kahle kakhulu, njenge-flocculant ebalulekile, kancane kancane ibe “umkhiqizo ovelele” embonini yokuhlanza indle ngenxa yokusebenza kwayo okuhle kakhulu kanye namathuba okusetshenziswa kwayo abanzi.

I-Polyaluminum chloride iyinhlanganisela ye-polymer engakhiqizi izinto eziphilayo enomphumela oqinile wokugobhoza. Itholakala ngokusabela kwe-polymerization kwe-aluminium chloride kanye ne-aluminium hydroxide ngaphansi kwezimo ezithile. Uma kuqhathaniswa ne-aluminium salt flocculants yendabuko (njenge-aluminium sulfate, i-aluminium salt coagulant, njll.), i-polyaluminum chloride esebenza kahle kakhulu inekhono elinamandla lokususa ukungcola, ikakhulukazi lapho ibhekene nokungcoliswa okuphezulu kanye nokungcola okukhulu kukawoyela. Ukusebenza kuvelele kakhulu uma kukhulunywa ngekhwalithi yamanzi. Isetshenziswe kabanzi emikhakheni eminingi efana nokwelashwa kwendle kamasipala, ukwelashwa kwendle yezimboni, kanye nokwelashwa kwendle yasekhaya.

Izinzuzo ze-polyaluminum chloride esebenza kahle kakhulu

1. Umphumela we-flocculation uyamangalisa

I-polyaluminum chloride esebenza kahle kakhulu ingakha ngokushesha inani elikhulu lama-floc amahle emanzini, ngaleyo ndlela imunce ngempumelelo izinto eziqinile ezimisiwe, izinto ze-colloidal kanye nama-microorganism emanzini. Ingamunca futhi isuse ngokushesha izinhlayiya ezimisiwe, amafutha, ama-ion ensimbi esindayo kanye nokunye ukungcola emanzini. Ikakhulukazi uma kubhekene nekhwalithi yamanzi eyinkimbinkimbi, umphumela ungcono kakhulu kune-flocculants yendabuko kasawoti we-aluminium. Ekuhlanzweni kwendle, i-polyaluminum chloride esebenza kahle kakhulu ingakhuphula ijubane lokuhlala kwethangi lokuthuthwa kwendle ngesikhathi esifushane, ngaleyo ndlela inciphise kakhulu umjikelezo wokwelashwa kwendle.

2.Uhla olubanzi lwesicelo

I-polyaluminium chloride esebenza kahle kakhuluingakwazi ukuzivumelanisa nezimo ezahlukahlukene zekhwalithi yamanzi, okuhlanganisa amanzi anomswakama ophezulu, indle enamafutha amaningi, amanzi aqukethe izinsimbi ezisindayo, kanye namanzi anomswakama ophansi okushisa, okubonisa ukuzivumelanisa nezimo okunamandla. Ingasusa kahle izinto eziqinile ezilengayo kanye nokungcola emanzini, futhi ingasetshenziswa kabanzi ekuphatheni indle emikhakheni ehlukene njengokuphathwa komasipala, imboni, kanye nezimayini. Isibonelo, ekuphatheni indle yasekhaya, amanzi angcolile e-pulp mill, amanzi angcolile e-metallurgical, amanzi angcolile embonini yokudla kanye nezinye izimo, i-polyaluminum chloride esebenza kahle kakhulu ingafinyelela imiphumela emihle kakhulu yokwelapha.

3. Isilinganiso esiphansi, ukusebenza kahle okuphezulu kanye nokonga amandla

I-polyaluminium chloride esebenza kahle kakhulu yenzelwe ukufeza umthamo omncane kanye nomphumela ongcono we-flocculation. Umthamo we-turbidity ephansi ungama-25-40% we-aluminium sulfate, kanti umthamo we-turbidity ephezulu ungama-10-25% we-aluminium sulfate. Lokhu akugcini nje ngokunciphisa izindleko zokusebenzisa amakhemikhali, kodwa futhi kunciphisa ukusetshenziswa kwamandla kanye nodaka enkambisweni yokwelapha indle. Ngenxa yensalela yayo ephansi ye-aluminium, kunciphisa ukungcola kwesibili kwezindawo zamanzi futhi kunciphisa kakhulu izindleko eziphelele zokwelashwa kwendle. Ngakho-ke, sekuyindlela ebalulekile yokonga izindleko nokuthuthukisa ukusebenza kahle ekusetshenzisweni okungokoqobo.

4. Inobungani nemvelo

Ukusetshenziswa kwe-polyaluminium chloride esebenza kahle kakhulu kunomthelela omncane emvelweni kanye nasezinsaleleni ze-aluminium eziphansi. Uma kuqhathaniswa nezinye izinto ezikhipha amakhemikhali, i-polyaluminium chloride iphephile futhi inomthelela omncane ku-pH kanye ne-TA yokungcola, ngakho-ke isidingo samakhemikhali sokulungisa i-pH kanye ne-TA sinciphile. Ikakhulukazi kumaphrojekthi amakhulu okwelapha indle kanye nokuvikela imvelo, sekuyindlela eluhlaza futhi enobungani nemvelo.

5. Ifaneleka ekushiseni okuphansi kanye nokwelashwa kwamanzi okunomswakama ophezulu

Ukwelashwa ngamanzi ngezikhathi zokushisa okuphansi kuyinselele evamile. Ikakhulukazi ebusika obubandayo, ukusebenza kahle kwama-flocculant amaningi endabuko kuzoncishiswa kakhulu. Kodwa-ke, i-polyaluminum chloride esebenza kahle kakhulu ingaqhubeka nokugcina umphumela ophezulu we-flocculation ngaphansi kwezimo zokushisa okuphansi. Ngaphezu kwalokho, lapho ukugcwala kwamanzi kuphezulu, i-PAC ikhombisa amakhono okucubungula aqinile futhi ingasusa ngempumelelo izinhlayiya ezilengisiwe nezinto ze-colloidal emanzini. Kumanzi anokungcola okukhulu kwamafutha, i-polyaluminum chloride esebenza kahle kakhulu nayo inomphumela omuhle kakhulu wokususa amafutha.

6. Zivumelanise nezinhlobo ezahlukene ze-pH

I-polyaluminium chloride esebenza kahle kakhulu iyakwazi ukuzivumelanisa nezimo ezishintshayo ku-pH yamanzi futhi ingasebenza ngempumelelo ebangeni elibanzi le-pH. Ngokuvamile, i-PAC ingagcina umphumela omuhle wokugeleza emanzini ngenani le-pH eliphansi (elinobuthi) noma eliphakeme (eliyi-alkaline), okwandisa ukusebenza kwayo ngaphansi kwezimo ezahlukahlukene zekhwalithi yamanzi. 5.0-9.0 vs 5.5-7.5

7. Thuthukisa ukusebenza kahle kokuthungwa kwenhlabathi futhi unciphise ivolumu yodaka

I-polyaluminum chloride esebenza kahle kakhulu isiza ukusheshisa ukuhlala kwezinhlayiya eziqinile emanzini angcolile futhi ithuthukisa ukusebenza kahle kwethangi lokuthuthwa kwamanzi ngokuthuthukisa ubuningi kanye nokuhlala kahle kwama-floc. Ngaphezu kwalokho, ngenxa yezinga eliphezulu lokupholimetha kwe-polyaluminum chloride esebenza kahle kakhulu, ama-floc akhiwe ayaqina futhi ahlala ngokushesha, ngaleyo ndlela anciphise inani lodaka olukhiqizwayo. Lokhu kubaluleke kakhulu ekuphathweni nasekulahlweni kodaka okulandelayo, futhi kunganciphisa izindleko kanye nobunzima bokuphathwa kodaka.

Izibonelo zokusetshenziswa kwe-polyaluminum chloride esebenza kahle kakhulu ekwelashweni kwamanzi amdaka

1. Ukuhlanza indle kamasipala

Emkhakheni wokwelashwa kwendle kamasipala, i-polyaluminum chloride esebenza kahle kakhulu ingasetshenziswa kabanzi ezigabeni zangaphambi kokwelashwa kanye nokwelashwa kwesibili kwezitshalo zamanzi. Ingasusa ngempumelelo izinto eziqinile ezilengisiwe, izinto ze-colloidal, amabhaktheriya kanye nezinye izinto ezincane emanzini, ithuthukise ikhwalithi yamanzi, futhi inikeze umthombo wamanzi osezingeni eliphezulu wokwelashwa kwebhayoloji okulandelayo. I-PAC isibe ngesinye sezinto ezithwala amanzi ezivamile ezitshalweni zokwelashwa kwendle emadolobheni amaningi ekhaya nakwamanye amazwe.

2. Ukwelashwa kwamanzi amdaka ezimbonini

Emkhakheni wokwelashwa kwamanzi amdaka ezimbonini, i-polyaluminum chloride esebenza kahle kakhulu nayo isetshenziswa kabanzi. Inomphumela omuhle wokwelashwa emanzini amdaka ezimbonini avela ekunyatheliseni nasekudayeni, ekwenzeni amaphepha, esikhumbeni, ekufakeni i-electroplating nakwezinye izimboni, futhi ingasusa ngempumelelo ukungcola okufana nombala, i-COD kanye ne-BOD. Isibonelo, kwezensimbi, kumandla kagesi, embonini yamakhemikhali, ekwenzeni amaphepha, ekucubunguleni ukudla nakwezinye izimboni, i-PAC ingasiza ekususeni izinsimbi ezisindayo, amabala kawoyela, izinhlayiya ezilengayo kanye nokunye ukungcola emanzini. Ikakhulukazi lapho kwelashwa amanzi amdaka anamafutha, i-PAC ibonise ikhono layo elihle kakhulu lokususa uwoyela futhi inganciphisa kakhulu okuqukethwe uwoyela ezindaweni zamanzi.

3. Ukwelashwa kwamanzi angcolile okumbiwa phansi

Emkhakheni wokwelashwa kwamanzi amdaka asezimayini, i-polyaluminum chloride esebenza kahle kakhulu ingasusa ngempumelelo amaminerali, inhlabathi kanye nezinye izinto ezilenga emanzini, inikeze ukwesekwa kokuvuselelwa kwamanzi kanye nokubuyiselwa kwemvelo ezindaweni zokumba. Njengoba ikhwalithi yamanzi ezindaweni zokumba iyinkimbinkimbi futhi ngokuvamile iqukethe inani elikhulu lezinto eziqinile ezilengayo kanye nezinsimbi ezisindayo, ukusebenza kahle okuphezulu kwe-polyaluminum chloride esebenza kahle kakhulu kuvelele kakhulu kulolu hlobo lokwelashwa kwamanzi amdaka.

Ngenjwayelo,i-polyaluminum chloride esebenza kahle kakhulu, njenge-flocculant enhle kakhulu yokwelapha indle, inezinzuzo ezibalulekile zobuchwepheshe kanye nezemvelo. Ikakhulukazi uma kugcwele ukungcola okukhulu, ikhwalithi yamanzi eyinkimbinkimbi, kanye nokungcola okukhulu kwamafutha, ingafinyelela imiphumela emihle kakhulu yokwelapha.
