Amathangi Okubhafa Omoya-mpilo — Ukuthuthukisa Ukwelashwa Kwamanzi Angcolile Ngokusimama Komhlaba Wonke
Ezweni lanamuhla, ukushoda kwamanzi, imithetho yezemvelo, nokukhula kwezimboni kukhuthaza isidingo sezinhlelo zokwelashwa kwamanzi angcolile eziphumelela kakhulu futhi eziqotho. Isisekelo sezinhlelo ezinjalo yi-Aeration Buffer Tank, isakhiwo esibalulekile esiklanyelwe ukulawula ukugeleza kwamanzi angcolile, ukugcina izinqubo eziphilayo ezizinzile, nokuthuthukisa ukusebenza kahle kokwelashwa.
I-Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel), umholi womhlaba wonke kwezobunjiniyela bamathangi okugcina kusukela ngo-2008, ibilokhu ihamba phambili ekwakheni, ekukhiqizeni, nasekunikezeni amathangi okugcina umoya (aeration buffer tanks) emaphrojekthi emazweni angaphezu kwe-100. Ngeminyaka eminingi yesipiliyoni, izitifiketi zamazwe omhlaba, kanye nezindawo zokukhiqiza ezithuthukisiwe, i-Center Enamel iqinisekisa ukuthi amathangi ayo okugcina umoya ahlinzeka ngokusebenza isikhathi eside, ukwethembeka, nokusebenza kahle.
1. Yini i-Aeration Buffer Tank?
I-Aeration Buffer Tank iyisiqukathi esikhethekile esisetshenziswa ezinhlelweni zokwelapha amanzi angcolile ukuthi:
Sigcine amanzi angcolile angenayo okwesikhashana
Silinganise ukushintshashintsha kokugeleza nomthwalo ongcolile
Sizolise izinqubo zokwelapha ezisebenzisa ibhayoloji
Sinciphise ukushaqeka kwe-hydraulic kumabhakede okugcina umoya noma izikhanyisi ezilandelayo
Sisize ukugcina umoya kahle nokusabalalisa umoya-mpilo
Ngokunikeza ukulinganisa kokugeleza nokuxubana okulawulwayo, lezi tanki zivikela amayunithi okwelapha angaphansi komhlaba, ziqinisekisa ukususwa okungaguquki kwezinto eziphilayo, izakhamzimba, kanye nezinto eziyisimiso. Zivame ukuhlanganiswa ezinhlelweni ze-activated sludge, ama-sequencing batch reactors (SBRs), ama-membrane bioreactors (MBRs), kanye nezinhlelo zokugaya ngokungabi bikho komoya-mpilo.
2. Ukubaluleka kwamathangi okugcina umoya-mpilo ezinhlelweni zokwelapha zesimanje
2.1 Ukulinganisa kokugeleza nokumunca ukushaqeka
Imifudlana yamanzi angcolile kamasipala neyemboni ayihlukani. Ukushintsha kokugeleza - ngenxa yokusetshenziswa kakhulu, amanzi emvula, noma ukukhishwa kwezimboni - kungadala ukushaqeka kwe-hydraulic okungalimaza ukusebenza kahle kokwelapha. Amathangi okugcina umoya-mpilo asebenza njengezinto ezimunca ukushaqeka, alinganisa ukugeleza okungenayo ukuze kugcinwe imithwalo ye-hydraulic ezinzile ezinhlelweni zokwelapha ezisebenzisa izinto eziphilayo.
2.2 Ukuthuthukiswa kokwelapha okusebenzisa izinto eziphilayo
Ukwelashwa kwamanzi angcolile ngokwezinto eziphilayo kuncike ezimweni ezizinzile, okubandakanya umoya-mpilo oncibilikile (DO), i-pH, namazinga ezakhamzimba. Amathangi okubhafa omoya-mpilo avumela:
Ukuhlanganisa amanzi angcolile
Ukudluliswa komoya-mpilo okulawulwayo ngohlelo lwe-aeration
Izimo ezizinzile zemiphakathi yamagciwane
Ukukhushulwa kokususwa komoya-mpilo wezinto zamakhemikhali (COD) nomoya-mpilo wezinto eziphilayo (BOD)
Lokhu kuthuthukisa ukusebenza kahle kokwelapha okuphelele kanye nekhwalithi yamanzi aphumayo.
2.3 Ukulawulwa Kokusebenza Nokuphepha
Amathangi okugcina umoya (aeration buffer tanks) anikeza abasebenzi amandla okuguquguquka nokulawula izimo zenqubo. Ngokulawula ukuhamba komoya wokungena (influent flow) kanye nezinga lomoya (aeration rates), abasebenzi bangavikela ukuphazamiseka kwenqubo, banciphise ukwanda kwamandla (energy spikes), futhi banciphise ubungozi bokugcwala noma ukwehluleka kokusebenza.
3. Izinto Ezibalulekile Zokuklama
Ukuklama ithangi elisebenzayo lokugcina umoya (aeration buffer tank) kudinga ukuhlaziywa okunemininingwane kwezobunjiniyela. Ithimba le-Center Enamel lihlolisisa lezi zici ezilandelayo:
3.1 Umthamo Wokuhamba Kwamanzi Nesikhathi Sokuhlala
Amathangi okugcina (buffer tanks) ayenziwa ngosayizi ngokusekelwe ezingeni eliphakeme lokuhamba kwamanzi (peak flow rates), ukuhamba kwamanzi okuphakathi nosuku (average daily flow), kanye nesikhathi esidingekayo sokuhlala (retention time). Ukwenza usayizi ofanele kuqinisekisa ukulinganisa okusebenzayo futhi kuvimbele ukudlula ngokushesha kwamanzi angcolile ethangini.
