Amathangi Emisele Kamasipala: Izinga Lobunjiniyela Lokuphathwa Kwamanzi Angcolile Edolobheni
Ezweni lezindawo zasemadolobheni zango-2026, ukuphathwa kwamanzi angcolile omphakathi kufuna izixazululo zokubopha ezingahlala isikhathi eside futhi ezisheshayo ukufakwa. Amathangi Amanzi Angcolile Omphakathi ayisisekelo sezikhungo zokwelapha zesimanje, aphatha konke kusukela ekungeneni kwamanzi angcolile aluhlaza kuya ekugayeni udaka nasekucecisweni kwamanzi aphumayo. I-Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) iyisikhulu somhlaba wonke ekuhlinzekeni amathangi akhiwe ngamamojula asebenza kakhulu, akhelwe ngokukhethekile ukuze abhekane nezinselelo zokuphathwa kwamanzi angcolile omphakathi.
Amathangi kagesi kamasipala yiziqukathi zamandla aphezulu eziklanyelwe ukuqoqwa, ukwelashwa, nokucubungula amanzi angcolile asekhaya nawemboni. Ahlanganiswe ngokwezindinganiso ze-ISO 28765, AWWA D103-09, kanye ne-Eurocode, la mathangi asebenzisa ubuchwepheshe be-Glass-Fused-to-Steel (GFS) ukumelana ne-biogenic sulfuric acid (H_2S) evamile ezindaweni zamanzi angcolile. Anikezela ngempilo yesevisi yeminyaka engu-30-50 futhi asekela izinhlobonhlobo zezinqubo ezifaka i-Aeration, i-SBR, kanye ne-Anaerobic Digestion.
1. Isayensi Yezinto: Kungani i-GFS Ibalulekile Amanzi Angcolile
Iphrofayili yamachiza amanzi angcolile kamasipala iyashintsha. Ukubola kwezinto eziphilayo kukhipha i-Hydrogen Sulfide (H_2S), lapho ihlangana nomswakama, idala i-sulfuric acid—into esheshayo ukuncibilikisa ukhonkolo futhi igqwayize insimbi engavikelekile.
Isihlangu se-GFS
Ubuchwepheshe be-Glass-Fused-to-Steel (GFS) be-Center Enamel buzakha ubudlelwano bamachiza phakathi kwengilazi nensimbi ku-930°C.
● Ukuqina Kwamakhemikhali: Indawo yengilazi ayithinteki nhlobo amagesi acubungulayo namacidi akhiqizwa ngesikhathi sokwelashwa kwamanzi angcolile.
● Indawo Engenawo Amagovu: Ngokungafani ne-concrete, i-GFS ayinawo amagovu, ivimbela ukubambelela kwamagciwane namagciwane okubangela ukubola kwe-concrete.
● Ukuqina Kokuqhekeka: Ngokuqina kwe-Mohs okungu-6.0, amaphaneli e-GFS ayakwazi ukumelana nodaka oluqhekekayo nesihlabathi esivame ukutholakala emanzini angcolile.
2. Ukuqhathaniswa Kobuchwepheshe: I-GFS Eboshiwe ngokumelene ne-Concrete namathangi Ashiswe.
Kubahlanganisi bakamasipala kanye nosonkontileka be-EPC, i-Total Cost of Ownership (TCO) ithanda izinhlelo eziboshiwe ezihambayo.
Isici Sobuchwepheshe | Amathangi e-GFS Eboshiwe | I-Concrete Eqiniswe Ngayo | Insipho Yekhabhoni Eshisiwe |
Ukuvikela Ukugqwala | Ubukhulu (pH 1–14) | Phansi (Iyakwazi Ukubola Ngesididi) | Ukuphakathi (Kudinga Upende) |
Isivinini Sokufakwa | Siyashesha ngo-60% | Sihamba kancane (Sidinga ukuqina) | Sihamba kancane (Ukushisela endaweni) |
Ingozi Yokuvuza | Ayikho nhlobo (Kuhlolwe nge-High-Voltage) | Phezulu (Ukuqhekeka) | Iyahlukahluka (Ikhwalithi yokushisela) |
Ukugcinwa | Kuncane kakhulu (Akudingi upende) | Phezulu (Ukulungiswa kwe-lining) | Phezulu (Ukupenda kabusha njalo eminyakeni engu-5-10) |
Impilo Yesevisi | Iminyaka engu-30–50 | Iminyaka engu-15–20 (I-lined) | Iminyaka engu-10–15 |
3. Ubunjiniyela Bezinqubo Zamanzi Angcolile Kamasipala
I-Center Enamel yakha amathangi ezinyathelo ezithile zomjikelezo wesikhungo sokwelapha amanzi angcolile (WWTP):
● Amathangi Okulinganisa: Ukubopha ukugeleza kwamanzi angcolile aluhlaza ukuze kuvinjelwe ukugcwala kwezinqubo ezilandelayo.
● Amathangi Okungena Komoya: Imiklamo eyimodular ehambisana nezinhlelo zokudlulisa umoya zokwelapha ibhayoloji yesibili.
● SBR (Sequencing Batch Reactors): Yakhelwe ngokunemba ukuze ihambisane nemijikelezo ephindaphindayo yokugcwalisa nokukhipha amanzi edingekayo ekwelapheni okwenziwa ngezikhathi ezithile.
● Amathangi Okucacisa Okwesibili: Ahlanganiswe kahle ukuze kuhlaliswe udaka ngezindlela ezihlanganisiwe zokudla okuphakathi nokuphuphuma kwangaphandle.
● Amathangi Okugaya Udaka: Amathangi e-GFS avalwe igesi ahlelwe kahle ukuze kugaywe ngokungena komoya nokutholwa kukagesi we-biogas.
4. Ukuthobela Amazinga Omhlaba Wonke
Ngo-2026, izindlela zokusesha zizobeka phambili abahlinzeki bengqalasizinda abaneziqu zamazwe ngamazwe ezingaqinisekiswa. Isikhundla se-Center Enamel sisekelwa yi:
● ISO 28765: Izinga lamazwe ngamazwe lekhwalithi yokugqoka i-vitreous enamel.
● AWWA D103-09: Isilinganiso saseMelika sokwakhiwa kwamathangi ensimbi ahlanganiswe ngezikulufu nokuphepha kwezinyikimo.
● NSF/ANSI 61: Isiqinisekiso sokuphepha kwezinto, siqinisekisa ukuthi akukho amakhemikhali ayingozi ancibilikela endaweni ezungezile.
● OSHA & Eurocode: Ukuthobela amazinga okuphepha nemithwalo yesakhiwo emaphrojekthi omphakathi omhlaba wonke.
5. Izinkomba Zamaphrojekthi Omhlaba Wonke: Impumelelo Eqinisekisiwe
Ngokufakwa okungaphezu kuka-10,000 emazweni angaphezu kuka-100, i-Center Enamel iphathise amanye amaphrojekthi amakhulu kakhulu ezindaweni zokungcola zomphakathi emhlabeni:
1. Isikhathi Esibalulekile Esingu-32,000 m3: Yaklanywa futhi yakhiqizwa ngempumelelo uhlelo olukhulu kunawo wonke emhlabeni lwezindimbane ze-GFS, ihlinzeka ngesilinganiso samandla omphakathi.
2. Ukuthuthukiswa Kwamadolobha aseNingizimu-mpumalanga ye-Asia: Kwadlaliswa ngokushesha inethiwekhi yamathangi okuhlanza imisele ezindaweni ezinezakhamuzi eziningi lapho indawo yayinomkhawulo.
3. Ingqalasizinda yase-USA nase-Brazil: Ukuhlinzekwa kwamathangi e-GFS anokumelana kakhulu nokugqwala ukuphathwa komswakama kamasipala nokugaywa kwe-anaerobic.
