Indima eyinhloko yokwelashwa kwamanzi
Ngesenzo esiphindwe kathathu sokungasebenzisi i-electro-neutralization, ibhuloho lokumunca kanye nenethi yokungenisa imvula, Iphakethe ingasusa ngokushesha izinto eziqinile ezilengayo, ama-colloid, izinsimbi ezisindayo (insimbi/i-cadmium/i-aluminium, njll.), izinto ezinemisebe kanye namafutha antantayo emanzini.
Ukwelashwa Kwamanzi Okuphuza: yenza ukungcoliswa kokungcola kube ngaphansi kuka-0.5 NTU, ukuze kuhlangatshezwane nezindinganiso zezempilo zikazwelonke.
Indlela eyinhloko yesikhathi eside yenqubomgomo yokuvikela imvelo yokukhuthaza intengo ye-PAC
Ukulungiswa kwemikhawulo yezemvelo kuholele ekuphumeni kwamandla okukhiqiza amancane naphakathi. Isibonelo, endaweni yokukhiqiza ye-PAC eGongyi, eHenan, intengo ye-Q1 ikhuphuke ngo-10% esikhathini esifushane ngenxa yemikhawulo yezemvelo ngo-2025. Ngokuhamba kwesikhathi, ukuhlolwa kwezemvelo kuqede amandla okukhiqiza aphansi (njengemikhiqizo ehlanzekile ekhiqizwa kusetshenziswa indlela yesigubhu), okuholele ekukhuleni kokugxilisa imboni kanye namandla amakhulu okuxoxisana ezinkampanini ezihamba phambili.
Amanzi okuphuza uketshezi lwe-polyaluminum chloride: isiqinisekiso esiyinhloko sokuhlanzwa kwamanzi okuphephile
I-polyaluminum chloride ewuketshezi olusezingeni lamanzi okuphuza iyi-coagulant ye-polymer engaxutshwe nalutho ehlanzekile kakhulu eyenzelwe ngqo ukuhlanzwa kwamanzi okuphuza. Ifomula yayo yamakhemikhali yi-[Al₂(OH)ₙCl₆−n]m[Al₂(OH)ₙCl₆−n]m. Lo mkhiqizo uhambisana ngokuqinile ne-"Hygienic Standard for Drinking Water" yaseShayina maqondana namazinga ezinsalela zensimbi esindayo (i-arsenic ≤0.0005%, i-lead ≤0.001%) kanye nokuqukethwe kwesisekelo sikasawoti (40%-60%). Uma kuqhathaniswa nemikhiqizo yezinga lezimboni, ibonisa izinzuzo ezihlukile:
I-polyaluminium chloride ewuketshezi yezinga lezimboni
I-polyaluminum chloride (PAC) ewuketshezi olusezingeni lezimboni, i-coagulant ye-polymer engaphili, inefomula yamakhemikhali [Al2(OH)nCl6−n]m[Al2(OH)nCl6−n]m. Yakha ngokusebenzisa i-hydrogen-oxygen ion bridging kanye ne-multivalent anion polymerization. Uma kuqhathaniswa ne-flocculants yendabuko njenge-aluminium sulfate, i-liquid PAC inikeza izinzuzo ezibalulekile.
Umkhuba wentengo ye-polyaluminum chloride eqinile yezinga lezimboni engxenyeni yokuqala ka-2025
Okulandelayo ukuhlaziywa okuphelele kwentengo ye-polyaluminum chloride (PAC) eqinile yezinga lezimboni yaseShayina engxenyeni yokuqala ka-2025, ngokusekelwe kudatha yakamuva yemakethe:
Uhlelo Lokuhlukaniswa Kwe-Polyferric Sulfate
Ngokwezindinganiso zikazwelonke, amafomu omkhiqizo kanye nezimo zokusetshenziswa, kunezinhlobo ezicacile ze-polyferric sulfate, kanje:
Umthelela wesikhathi eside wezinqubomgomo zemvelo entengo ye-polyaluminum chloride
Ukulungiswa kwemikhawulo yezemvelo kuholele ekuphumeni kwamandla okukhiqiza amancane naphakathi. Isibonelo, endaweni yokukhiqiza ye-PAC eGongyi, eHenan, intengo ye-Q1 ikhuphuke ngo-10% esikhathini esifushane ngenxa yemikhawulo yezemvelo ngo-2025. Ngokuhamba kwesikhathi, ukuhlolwa kwezemvelo kuqede amandla okukhiqiza aphansi (njengemikhiqizo ehlanzekile ekhiqizwa kusetshenziswa indlela yesigubhu), okuholele ekukhuleni kokugxilisa imboni kanye namandla amakhulu okuxoxisana ezinkampanini ezihamba phambili.
Uhla lwe-pH olufanele kakhulu lwe-polyaluminum chloride emanzini angcolile okwenza iphepha
Uma i-polyaluminum chloride isetshenziswa ukwelapha indle yokwenza iphepha, ububanzi be-pH obuhle kakhulu buthintwa yizici eziningi. Izifundo ezahlukene kanye nezicelo ezisebenzayo zinikeza ububanzi obuhlukile kancane, ngokuvamile phakathi kuka-6 no-9. Lokhu okulandelayo yizimo ezithile kudatha ehlukene:
Yiziphi izimfanelo zamanzi ezikhethekile ezifanele ama-coagulants anosawoti omningi
I-flocculant enosawoti omningi (njenge-polyferric sulfate enezinga lesisekelo sosawoti elingu-12% noma ngaphezulu) ifaneleka kakhulu kulezi zimo ezilandelayo zekhwalithi yamanzi ngenxa yesakhiwo sayo eside se-molecular chain, ikhono eliqinile lokunciphisa uketshezi kanye nesivinini esisheshayo sokufakwa kwenhlabathi:
