Indasteri grade liquid polyaluminium chloride

I. Tlhaloso le Litšoaneleho

Mokelikeli oa boemo ba indasteri Polyaluminium Chloride (PAC), e leng inorganic polymer coagulant, e na le foromo ea lik'hemik'hale [Al2(OH)nCl6−n]m[Al2​(OH)n​Cl6−n​]m E theha ka bridging ea hydrogen-oxygen ion le polymerization ea anion e mengata. Ha ho bapisoa le li-flocculants tsa setso tse kang aluminium sulfate, PAC ea metsi e fana ka melemo e mengata:

• Phallo e sebetsang hantle haholo: boima bo boholo ba limolek'hule le tefiso e phahameng e ka khabisoa ka potlako likaroloana tsa colloidal ka metsing, tsa etsa lipalesa tse kholo le tse teteaneng tsa alum, mme lebelo la sedimentation le eketseha ka 30%.
• Ho feto-fetoha ha maemo ho pharaletseng: pH e sebetsang ka bophara (5.0-9.0), ts'ebetso e tsitsitseng tikolohong ea mocheso o tlase, e sebetsang hantle bakeng sa metsi a mahlahahlaha a phahameng, metsi a litšila a oli le metsi a litšila a tšepe e boima.
• Ho senyeha ho fokolang le ho sireletseha: ho senya ho fokotsehile ho feta ea tšepe ea letsoai ea coagulant, 'me masala a tšepe a boima a kopana ka thata le maemo a naha (a kang arsenic ≤ 0005%, lead ≤ 0.006%).

II. Theknoloji ea tlhahiso le lihlopha tsa theknoloji

Tlhahiso ea indasteri ea PAC ea metsi haholo e ipapisitse le lits'ebetso tse latelang:

• Metal aluminium mokhoa: molora oa aluminium le slag ea aluminium li sebelisoa e le lisebelisoa tse tala, ebe li hōlile le ho polymerize ka hydrochloric acid. E theko e tlaase empa e thata ho laola bohloeki, kahoo e loketse ho hloekisa mekhoa e tloaelehileng ea likhoerekhoere tsa indasteri.
• Mokhoa o sebetsang oa aluminium hydroxide: ho sebelisoa phofo e phahameng ea aluminium hydroxide, 'me tekanyo ea motheo ea letsoai e fetoloa ka mor'a ho qhibiliha ha acid tlas'a khatello (40% -90%). Sehlahisoa se na le lintho tse tlaase tsa tšepe e boima 'me se loketse boleng bo phahameng ba metsi.
• Mokhoa oa pele oa betri: chip ea aluminium (anode) le cathode ea tšepe li sebelisoa ka hydrochloric acid ho itsoara ka mocheso, e bolokang matla le e sebetsang hantle, empa e hloka ho laola ka thata litšila tsa tšepe tse boima.
• Ts'ebetso ea katoloso ea ho omisa: Mokelikeli oa PAC o ka felloa ke metsi ka har'a tora ea ho fafatsa ho hlahisa lihlahisoa tse tiileng, empa mofuta oa mokelikeli o felisa mohato oa ho qhibiliha mme ts'ebetso e bonolo haholoanyane.

3. Maemo a kopo a mantlha

ho lahla litšila tsa indasteri

• Ho hatisa le ho daea / metsi a litšila a letlalo: sekhahla sa decolorization se fihla ho feta 85%, ka katleho se senya COD (tlhoko ea oksijene ea lik'hemik'hale).
• Fluoride/metsi a litšila a tšepe a kotsi: li-ion tsa fluoride le lintho tse chefo joalo ka loto le chromium li tlosoa ke pula e ngata.
• Metsi a litšila a ho etsa pampiri/mashala: potlakisa ho putlama ha mashala a thuntsoeng, ho khutlisa lintho tse tiileng tse sebetsang, le ho fokotsa Water Cotente ya seretse.

Tsamaiso ea tsamaiso ea metsi a litoropo

• Tlhoekiso ea metsi: tlosa lintho tse tiileng tse fanyehiloeng le li-colloid ka har'a letamo la metsi le metsing a ka tlas'a lefatše, 'me u fokotse moferefere ho ba ka tlase ho 0.5 NTU.
• Masepala tsamaiso ea likhoerekhoere: ho kopantswe le Polyacrylamide ka ntlafatsa bokgoni ba seretse dewatering le fokotsa litšenyehelo lahla.

Tokiso e khethehileng ea boleng ba metsi

• Deionization ea 'mele oa metsi a radioactive;
• Ho tlosoa ha phosphorus le naetrojene metsing a litšila a aquaculture ho thibela eutrophication.

IV. Lintlha tsa bohlokoa tsa ts'ebetso le litlhaloso tsa tšebeliso

Lintlha tsa bohlokoa:

• tekanyo: Tekanyetso e tloaelehileng ea mokelikeli PAC ke 3-40 kg/1000 lithane tsa metsi, 'me boleng bo botle bo lokela ho khethoa ke teko ea beaker.
• Litlhoko tsa ho hlapolla: eketsa ka kotloloho kapa u lokise tharollo ea 5% -10% ho qoba khatello e feteletseng e lebisang ho hloleheng ha hydrolysis.

Ho se lumellane: Ho bolokoa ka li-oxidizing tse matla le li-solvents tsa organic ho thibetsoe ho thibela ho senngoa ha meaho ea polymer.

V. Mekhoa ea Ntlafatso le Liphephetso tsa Tikoloho

• Tlhahiso e tala: Ntlafatsa ts'ebetso ka molora oa lintsintsi, molora oa mashala le litšila tse ling tse tiileng e le lisebelisoa tse tala ho fokotsa tšebeliso ea lisebelisoa.
• Tšebeliso e nepahetseng: Foromo e entsoeng ka mokhoa o ikhethileng oa PAC e etselitsoe mefuta e fapaneng ea metsi a litšila (mohlala, metsi a litšila a mafura / letsoai le phahameng).
• Taolo ea aluminium e setseng: ntlafatsa ts'ebetso ea polymerization ho fokotsa masala a aluminium ion metsing le ho qoba likotsi tsa tikoloho.

Mokelikeli oa indasteri oa polyaluminium chloride o fetohile moemeli oa lik'hemik'hale o ke keng oa nkeloa sebaka tsamaisong ea sejoale-joale ea kalafo ea metsi ka lebaka la litšoaneleho tsa eona tsa ts'ebetso e phahameng, palo e pharaletseng le theko e tlase. Lipatlisiso tsa nako e tlang li hloka ho tsoela pele ho leka-lekanya ntlafatso ea ts'ebetso le polokeho ea tikoloho, le ho khothaletsa ts'ebeliso ea eona e ncha tlasa sepheo sa "zero discharge".
