I-Polyaluminum Chloride (PAC): Isikhokelo Sokusetyenziswa kunye neengcebiso Zokugcina Ezikhuselekileyo

I-Polyaluminum Chloride(PAC) yi-coagulant eqhelekileyo ye-polymer engaphiliyo. Inkangeleko yayo idla ngokubonakala njengomgubo otyheli okanye omhlophe. Ineenzuzo zesiphumo esihle kakhulu sokujiya, idosi ephantsi kunye nokusebenza okulula. I-Polyaluminum Chloride isetyenziswa kakhulu kwicandelo lokunyanga amanzi ukususa izinto eziqinileyo ezixhonyiweyo, imibala, ivumba kunye nee-ion zesinyithi, njl.njl., kwaye inokucoca umgangatho wamanzi ngempumelelo. Ukuqinisekisa ukusebenza kwayo kunye nokhuseleko ngexesha lokusetyenziswa, kufuneka kulandelwe iindlela ezichanekileyo zokusetyenziswa kunye nokugcinwa.

Indlela yokusebenzisa i-PAC kuNyango lwaManzi

Kukho iindlela ezimbini eziphambili zokusebenzisa iPolyaluminum Chloride. Enye kukufaka imveliso ngqo emanzini ukuze icocwe, enye kukuyilungisa ibe sisisombululo uze uyisebenzise.

Ukongeza ngokuthe ngqo: Yongeza iPolyaluminum Chloride ngqo emanzini aza kunyangwa, kwaye uyifake ngokwemilinganiselo efanelekileyo efunyenwe kuvavanyo. Umzekelo, xa unyanga amanzi omlambo, izinto eziqinileyo zePolyaluminum Chloride zingongezwa ngokuthe ngqo.

Lungisa isisombululo: Lungisa iPolyaluminum Chloride ibe sisisombululo ngokwemilinganiselo ethile, uze uyifake emanzini aza kunyangwa. Xa ulungisa isisombululo, qala ngokufudumeza amanzi ade abile, uze wongeze kancinci iPolyaluminum Chloride uze uvuselele rhoqo de iPolyaluminum Chloride ichitheke ngokupheleleyo. Isisombululo esilungisiweyo kufuneka sisetyenziswe kwiiyure ezingama-24. Nangona songeza enye inkqubo, isiphumo singcono.

Ukhuseleko lokuphatha iPolyaluminum Chloride

Uvavanyo lwebhotile:Kukho izinto ezininzi ezingaziwayo kwilindle. Ukuze kuchongwe idosi ye-flocculant, kuyimfuneko ukumisela imodeli engcono ye-PAM kunye nedosi efanelekileyo yemveliso ngovavanyo lwebhotile.

Lawula ixabiso le-pH:Xa usebenzisa iPolyaluminum Chloride, ixabiso le-pH lomgangatho wamanzi kufuneka lilawulwe. Kumanzi amdaka ane-asidi, kufuneka kongezwe izinto ze-alkaline ukuze kulungiswe ixabiso le-PH libe kuluhlu olufanelekileyo; kumanzi amdaka ane-alkaline, kufuneka kongezwe izinto ze-asidi ukuze kulungiswe ixabiso le-PH libe kuluhlu olufanelekileyo. Ngokulungisa ixabiso le-pH, isiphumo sokujiya kwePolyaluminum Chloride sinokwenziwa ngcono.

Ukuxuba nokuVuselela:Ukuxuba nokuxubha ngokufanelekileyo kufuneka kwenziwe xa kusetyenziswa iPolyaluminum Chloride. Ngokuxubha ngoomatshini okanye ngokufaka umoya, iPolyaluminum Chloride idibana ngokupheleleyo nezinto eziqinileyo ezixhonyiweyo kunye nee-colloids emanzini ukuze zenze ii-flocs ezinkulu, nto leyo eyenza kube lula ukuhlala kunye nokuhluza. Ixesha elifanelekileyo lokuxubha ngokubanzi yimizuzu eli-1-3, kwaye isantya sokuxubha yi-10-35 r/min.

Nika ingqalelo kubushushu bamanzi:Ubushushu bamanzi buchaphazela nempembelelo yokujiya kwePolyaluminum Chloride. Ngokubanzi, xa ubushushu bamanzi buphantsi, impembelelo yokujiya kwe-polyaluminum chloride iya kucotha kwaye ibe buthathaka; ngelixa xa ubushushu bamanzi buphezulu, impembelelo iya kuphucuka. Ke ngoko, xa usebenzisa iPolyaluminum Chloride, uluhlu olufanelekileyo lobushushu kufuneka lulawulwe ngokweemeko zomgangatho wamanzi.

Ulandelelwano lwedosi:Xa usebenzisa iPolyaluminum Chloride, kufuneka kuqwalaselwe ulandelelwano lwedosi. Kwiimeko eziqhelekileyo, iPolyaluminum Chloride kufuneka yongezwe emanzini kuqala ngaphambi kweenkqubo zonyango ezilandelayo; ukuba isetyenziswa kunye nezinye iiarhente, kufuneka kwenziwe indibaniselwano efanelekileyo ngokusekelwe kwiimpawu zeekhemikhali kunye nendlela esebenza ngayo iarhente, kwaye kufuneka ulandele umgaqo wokongeza i-coagulant kuqala uze emva koko wongeze i-coagulant aid.

Iingcebiso zokugcina iPAC zokusetyenziswa kwimizi-mveliso

Indawo yokugcina evaliweyo:Ukuze kuthintelwe ukufunxwa komswakama kunye ne-oxidation, iPolyaluminum Chloride kufuneka igcinwe kwindawo eyomileyo, epholileyo, nengena umoya kakuhle, kwaye igcine isitya sivaliwe. Kwangaxeshanye, kuphephe ukuxubana nezinto ezinobungozi nezinobungozi ukuze kuthintelwe ingozi.

Ayinamanzi kwaye ayifuni ukugqunywa:I-Polyaluminum Chloride ifunxa lula umswakama kwaye inokuhlangana emva kokugcinwa ixesha elide, nto leyo echaphazela isiphumo sokusetyenziswa. Ke ngoko, kufuneka kunikwe ingqalelo ekuthinteleni umswakama ngexesha lokugcina ukuze kuthintelwe ukudibana ngqo nomhlaba. Izixhobo ezingangeni kumswakama zingasetyenziselwa ukwahlulahlula. Kwangaxeshanye, kuyimfuneko ukujonga rhoqo ukuba imveliso ihlangene na. Ukuba kufunyenwe ukuhlangana, kufuneka kujongwane nako ngexesha.

Kude neshushu:Ukuvezwa ixesha elide elangeni kunokubangela ukuxinana kwePolyaluminum Chloride kwaye kuchaphazele ukusebenza kwemveliso; i-crystallization inokwenzeka kumaqondo obushushu aphantsi. Ngoko ke ukukhanya kwelanga ngqo kunye namaqondo obushushu aphezulu kufuneka kuthintelwe. Kwangaxeshanye, gcina imiqondiso yezilumkiso zokhuseleko ibonakala ngokucacileyo kwindawo yokugcina.

Ukuhlolwa rhoqo:Imeko yokugcina yePolyaluminum Chloride kufuneka ihlolwe rhoqo. Ukuba kufunyenwe ukuhlangana, ukutshintsha kombala, njl.njl., kufuneka kujongwane nayo ngokukhawuleza; kwangaxeshanye, umgangatho wemveliso kufuneka uvavanywe rhoqo ukuqinisekisa ukusebenza kwayo okuzinzileyo.

Landela imigaqo yokhuseleko:Ngexesha lenkqubo yokugcina, kufuneka ulandele imigaqo yokhuseleko efanelekileyo kwaye unxibe impahla yokukhusela, iiglavu kunye nezinye izixhobo zokukhusela; kwangaxeshanye, gcina imiqondiso yesilumkiso sokhuseleko kwindawo yokugcina ibonakala ngokucacileyo kwaye ulandele imigaqo yokhuseleko efanelekileyo ukuthintela iingozi ezifana nokutya ngengozi okanye ukuchukumisa ngengozi.

I-Polyaluminium chloride isetyenziswa kakhuluI-Flocculant kuNyango lwaManziUkuqinisekisa ukusebenza kwayo okuphezulu kunye nokhuseleko, kubalulekile ukunamathela kwiindlela ezifanelekileyo zokusetyenziswa kunye nokugcinwa. Ngokulandela le migaqo, unokufumana iingenelo ezininzi ze-PAC kwi-water trea.
