1. Usoro ọgwụgwọ

1.1 Mmiri mmiri ọgwụ

Mmiri mmiri ozuzo bụ otu n'ime ụzọ a na-ejikarị agwọ mmiri mkpofu sodium sulfide. N'ime usoro a, a na-agbakwunye nnu ígwè dị ka nnu ígwè (ferrous sulfate, ferric chloride) ma ọ bụ nnu ọla kọpa na mmiri mkpofu. Ions sulfide dị na sodium sulfide na-emeghachi omume na ion ígwè, na-ebute nguzobe nke sulfide metal na-adịghị edozi. Mgbe mmeghachi omume mmiri ozuzo gasịrị, a na-eme nkewa siri ike - mmiri mmiri site na sedimentation ma ọ bụ nzacha, na-ewepụ sulfide nke ọma na mmiri mkpofu. Usoro a dị nnọọ mfe, ọnụ ahịa - dị irè, ma dị mma maka ịgwọ mmiri mkpofu na nnukwu sulfide.

1.2 Ọgwụgwọ Oxidation

Ọgwụgwọ oxidation nwere ike ịtụgharị sulfide na mmiri mkpofu sodium sulfide ka ọ bụrụ ihe na-adịghị emerụ ahụ. Ụzọ oxidation na-emekarị gụnyere ikuku oxidation, chlorine oxidation, na usoro oxidation dị elu (AOPs).

• Nkwụsị Ikuku : Ọ bụrụ na e nwere ihe ndị na-akpali akpali dịka manganese dioxide, a na-etinye ikuku n'ime mmiri mkpofu. N'ọnọdụ ikuku, a na-eme ka sulfide ghọọ ihe na-eme ka ọ dị ka sulfur ma ọ bụ sulfate. Usoro a na-arụ ọrụ nke ọma mana ọ chọrọ oge mmeghachi omume ogologo oge ma dabara adaba maka ịgwọ mmiri mkpofu na obere mkpokọta sulfide.

• Ngwunye Chlorine : A na-eji Chlorine - nke nwere ihe ndị na-eme ka ọ dị ọcha dịka sodium hypochlorite ma ọ bụ gas chlorine iji mee ka sulfide dị ọcha. Ngwunye Chlorine na-adị ngwa ma dị irè, mana ọ nwere ike ịkpata ihe na-emerụ ahụ site na ngwaahịa, yabụ ọ dị mkpa iji nlezianya nyochaa ọnụọgụgụ ọgwụ ahụ.

• Usoro Oxidation Advanced (AOPs) : AOPs, dịka Fenton oxidation na ozone oxidation, na-emepụta radicals hydroxyl dị oke arụ ọrụ. Radicals ndị a nwere ike ime ka sulfide dị ngwa ngwa ma mee ka ọ dị ka mineral. Dịka ọmụmaatụ, oxidation Fenton na-eji hydrogen peroxide na ions ferrous emepụta radicals hydroxyl, nke nwere ike ịgwọ ma mmiri mkpofu sulfide dị ala ma dị elu nke ukwuu.

1.3 Ọgwụgwọ ndu

Ọgwụgwọ nke ndu na-eji microorganisms weda sulfide n'ime mmiri ahịhịa. Usoro ọgwụgwọ anaerobic, dị ka mgbaze anaerobic, nwere ike ịtụgharị sulfide ka ọ bụrụ gas hydrogen sulfide n'okpuru ọnọdụ anaerobic, nke enwere ike wepụ ya site na gas - usoro nchịkọta. Ọgwụgwọ usoro ndụ nke ikuku na-agụnye microorganisms aerobic nke na-eme ka sulfide na sulfate dị ka akụkụ nke usoro metabolic ha. Ọgwụgwọ nke ndu bụ ihe enyi na gburugburu ebe obibi ma na-adigide, mana ọ chọrọ ọnọdụ arụ ọrụ kwụsiri ike yana oge ọgwụgwọ dị ogologo.

2.2 Akpachara anya arụ ọrụ

• Njikwa Ọnụọgụ Ọgwụ Reagent : N'ọgwụgwọ mmiri ozuzo na oxidation nke kemịkalụ , njikwa ziri ezi nke ọnụọgụ ọgwụ reagent dị oke mkpa. Enweghị usoro ọgwụgwọ zuru oke nwere ike ibute ọgwụgwọ na-ezughị ezu, ebe oke usoro ọgwụgwọ anaghị eme naanị ka ọnụ ahịa ọgwụgwọ dịkwuo elu kamakwa ọ nwere ike ibute mmetọ nke abụọ. Dịka ọmụmaatụ, n'oge mmiri ozuzo kemịkalụ, oke nnu ígwè nwere ike ibute ọnụnọ nke ion ígwè fọdụrụ na mmiri a gwọrọ.

• Njikwa pH : Uru pH nke mmiri mkpofu na-emetụta nke ukwuu arụmọrụ ọgwụgwọ. N'oge mmiri ozuzo kemịkalụ, ihe ndị na-eme ka ígwè sulfide dị iche iche na-etolite nke ọma n'ime oke pH akọwapụtara. N'ọgwụgwọ oxidation, ọnụego mmeghachi omume oxidation na ihe mejupụtara ngwaahịa nwekwara njikọ chiri anya na uru pH. Ya mere, nlekota na nhazi nke uru pH na-aga n'ihu n'oge usoro ọgwụgwọ dị mkpa.

• Nlekọta Ngwaọrụ : Ọrụ nlekọta mgbe niile nke akụrụngwa ọgwụgwọ, dịka ọkpọkọ, igwekota ihe, na tankị sedimentation, dị mkpa iji hụ na usoro ọgwụgwọ ahụ na-arụ ọrụ nke ọma. A ga-eji ihe ndị na-eguzogide nchara eme ihe maka akụrụngwa ndị metụtara mmiri mkpofu sodium sulfide iji mee ka akụrụngwa ahụ dịgide ogologo oge.

2.3 Nchekwa gburugburu ebe obibi
