Iingenelo ze-polyaluminum chloride esebenza kakuhle kakhulu kunyango lwamanzi amdaka

Ngokukhawuleziswa kophuhliso lwemizi-mveliso, ukukhutshwa kwamanzi amdaka kuye kwaba yingxaki enkulu ekukhuselweni kokusingqongileyo kwihlabathi liphela. Eyona nto iphambili ekunyangweni kwamanzi amdaka kukukhetha nokusetyenziswa kwawo.ii-flocculantskwinkqubo yokucoca. Kwiminyaka yakutshanje, i-polyaluminum chloride (PAC) esebenza kakuhle kakhulu, njenge-flocculant ebalulekileyo, iye yaba "yimveliso ebalaseleyo" kwishishini lokucocwa kwamanzi amdaka ngenxa yokusebenza kwayo okugqwesileyo kunye namathuba okusetyenziswa kwayo ngokubanzi.

I-Polyaluminum chloride yi-polymer compound engaphiliyo enefuthe elinamandla lokuqunjelwa. Ifunyanwa yi-polymerization reaction ye-aluminium chloride kunye ne-aluminium hydroxide phantsi kweemeko ezithile. Xa ithelekiswa ne-aluminium salt flocculants yendabuko (efana ne-aluminium sulfate, i-aluminium salt coagulant, njl.njl.), i-polyaluminum chloride esebenza kakuhle inamandla okususa ungcoliseko, ingakumbi xa ijongene nokudumba okuphezulu kunye nongcoliseko olukhulu lweoyile. Ukusebenza kwayo kugqwesileyo ngakumbi xa kufikwa kumgangatho wamanzi. Isetyenziswe kakhulu kwiindawo ezininzi ezifana nonyango lwelindle lukamasipala, unyango lwelindle lemizi-mveliso, kunye nonyango lwelindle lasekhaya.

Iingenelo ze-polyaluminum chloride esebenza kakuhle kakhulu

1. Isiphumo sokutyibilika kwe-flocculation siyamangalisa

I-polyaluminum chloride esebenza kakuhle inokwenza ngokukhawuleza inani elikhulu lee-flocs ezintle emanzini, ngaloo ndlela ifunxa ngokufanelekileyo izinto eziqinileyo ezixhonyiweyo, izinto ze-colloidal kunye neentsholongwane emanzini. Ingafunxa ngokukhawuleza kwaye isuse amasuntswana axhonyiweyo, igrisi, ii-ion zesinyithi ezinzima kunye nezinye izinto ezingcolisayo emanzini. Ingakumbi xa kujongwana nomgangatho wamanzi onzima, isiphumo siphezulu kakhulu kunee-flocculants zetyuwa ye-aluminium yendabuko.
