Ọgwụgwọ mmiri bụ akụkụ dị mkpa nke nchekwa gburugburu ebe obibi na ahụike ọha na eze, ebumnuche ya bụkwa iji hụ na mmiri dị mma ma mezuo mkpa nke ọtụtụ ojiji. N'ime ọtụtụ ụzọ ọgwụgwọ mmiri,polyaluminum chlorideA na-ahọrọ (PAC) nke ukwuu maka njirimara pụrụ iche ya na mmetụta coagulation dị irè.
Mmetụta coagulation dị irè: PAC nwere arụmọrụ coagulation dị mma ma nwee ike iwepụ ihe ndị na-adịghị mma dịka ihe siri ike a kpọchiri akpọchi, colloids na ihe ndị na-adịghị agbaze na mmiri ma melite mma mmiri.
Usoro nke polyaluminium chloride (PAC) dị ka coagulant gụnyere mkpakọ nke oyi akwa okpukpu abụọ nke eletriki, nkwụsịtụ chajị na njide net. Mkpakọ nke oyi akwa eletriki okpukpu abụọ pụtara na mgbe etinyere PAC na mmiri, ion aluminum na ion chloride na-emepụta oyi akwa adsorption n'elu nke ihe colloidal, si otú a na-akpakọ oyi akwa eletrik okpukpu abụọ n'elu nke ihe colloidal, na-eme ka ha ghara ịdị ike ma gbakọta; njikọ adsorption bụ Cations dị na molekul PAC na-adọta ibe ha na ebubo na-adịghị mma n'elu nke ihe colloidal, na-emepụta usoro "akwa" iji jikọọ ọtụtụ ihe colloidal; mmetụta netting bụ site na mmetụta adsorption na njikọ nke molekul PAC na ihe colloidal, nke na-ejikọta ihe colloidal. A na-ejide ya na netwọk nke molekul coagulant.
Ojiji nke polyaluminum chloride maka ọgwụgwọ mmiri
Ma e jiri ya tụnyere ihe ndị na-adịghị mma, o meela ka mmetụta nke agba agba dịkwuo mma nke ukwuu. Usoro ọrụ ya bụ na PAC nwere ike ịkwalite molekul agba ka ha mepụta obere flocs site na mkpakọ ma ọ bụ mwepụ nke oyi akwa okpukpu abụọ nke eletriki.
Mgbe ejiri PAM na PAC mee ihe, molekul anionic organic polymer nwere ike iji mmetụta njikọ nke agbụ molekul ogologo ha mepụta flocs dị arọ site na nkwado nke onye na-eme ka ihe ghara ịdị ike. Usoro a na-enyere aka imeziwanye mmetụta nhazi ma mee ka ion metal dị arọ dị mfe iwepụ. Na mgbakwunye, ọnụ ọgụgụ buru ibu nke otu amide dị na agbụ akụkụ nke molekul anionic polyacrylamide nwere ike ịmepụta njikọ ionic na -SON na molekul agba. Nhazi nke njikọ kemịkalụ a na-ebelata ike ịgbaze nke flocculant organic na mmiri, si otú a na-akwalite nhazi ngwa ngwa na mmiri ozuzo nke flocs. Usoro njikọ miri emi a na-eme ka ọ sie ike karịa maka ion metal dị arọ ịgbapụ, na-eme ka arụmọrụ na mmetụta nke ọgwụgwọ dịkwuo mma.
Maka iwepụ phosphorus, a pụghị ileghara irè nke polyaluminum chloride anya. Mgbe etinyere ya na mmiri mkpofu nwere phosphorus, ọ nwere ike ịmịpụta hydrolyze iji mepụta ion ígwè aluminom trivalent. ion a na-ejikọ na phosphates na-agbaze na mmiri mkpofu, na-agbanwe nke ikpeazụ ka ọ bụrụ ihe na-eme ka phosphate ghara ịgbaze. Usoro ntụgharị a na-ewepụ ion phosphate nke ọma na mmiri mkpofu ma na-ebelata mmetụta ọjọọ nke phosphorus na ahụ mmiri.
Tinyere mmeghachi omume kpọmkwem na phosphate, mmetụta coagulation nke polyaluminum chloride na-arụkwa ọrụ dị mkpa na usoro mwepụ phosphorus. Ọ nwere ike ime ka a na-abanye ma na-ejikọta ya site na ịpịkọta oyi akwa chajị n'elu ion phosphate. Usoro a na-eme ka phosphates na ihe ndị ọzọ na-emerụ ahụ dị n'ime mmiri mkpofu gbakọta ngwa ngwa wee ghọọ mkpọkọ, na-emepụta flocs ndị dị mfe idozi.
Ihe kacha mkpa bụ na maka ihe siri ike ndị a kpọchiri akpọchi nke e mepụtara mgbe etinyere ihe na-ewepụ phosphorus, PAC na-eji usoro pụrụ iche ya nke na-ejide ihe na mmetụta siri ike nke na-egbochi chaja iji kwalite uto na ọkpụrụkpụ nke ihe siri ike ndị a kpọchiri akpọchi, wee jikọta, chịkọta, ma jupụta n'ime obere ihe ndị buru ibu. Ihe ndị a na-adaba na oyi akwa ala, site na nkewa siri ike na mmiri mmiri siri ike, enwere ike ịpụpụ mmiri mmiri dị n'elu, si otú a na-enweta mwepụ phosphorus dị irè. Usoro usoro anụ ahụ na kemịkalụ dị mgbagwoju anya a na-eme ka arụmọrụ na nkwụsi ike nke ọgwụgwọ mmiri mkpofu dị irè, na-enye nkwa siri ike maka nchedo gburugburu ebe obibi na iji akụrụngwa mmiri eme ihe.
