Iyini Ithangi Lokwelashwa Kwendle? Umhlahlandlela Ophelele Wamaphrojekthi Akamasipala Nezimboni
Ithangi lokwelashwa kwendle iyisitsha sokugcina — ngokuvamile i-GFS eboshiwe (ingilazi ehlanganiswe nensimbi), insimbi eshisiwe, noma ithangi likakhonkolo — eligcina indle ngesikhathi sezigaba zokwelashwa ngokomzimba, ngokwebhayoloji nangamakhemikhali, okuhlanganisa ukulinganisa, ukungenisa umoya, ukuhlala kwezinto eziphansi nokucacisa. Liyisitsha esiyinhloko senqubo yanoma yisiphi isikhungo sokwelashwa kwendle (STP).
Omasipala nabaqhubi bezimboni babhekana nosongo oluqhubekayo ngaphakathi kwala mathangi: indle engcolile ikhiqiza i-hydrogen sulfide (H2S) nama-asidi e-organic ahlasela ngamandla izindawo zensimbi nokhonkolo. Ukukhetha into engalungile yethangi kuguqula impahla yeminyaka engu-20 ibe umthwalo wokulungisa weminyaka emi-5. Lo mhlahlandlela uchaza ukuthi amathangi okwelapha indle asebenza kanjani, yiziphi izinto ezimelana nalesi simo esonakalisayo, nokuthi kungani amathangi e-GFS aklanywe ngobunjiniyela abe yisinqumo sokuqala ezikhungweni zokwelapha emazweni angaphezu kwe-100.
1. Iyini Ithangi Lokwelashwa Kwendle futhi Lisebenza Kanjani?
Ukulinganisa nokugcina: Ithangi lokuqala emgqeni wokuhlanza lithola ukugeleza kwendle okushintshashintshayo futhi lilinganise umthwalo wamanzi nowezinto eziphilayo, livikele izigaba zezinto eziphilayo ezilandelayo emithwalweni eshokozayo.
Ukuhlala nokucacisa: Amathangi okuhlukanisa okuyisisekelo nawesibili avumela izinto eziqinile ezihlalayo ukuba zihlukane noketshezi. Izindonga zamathangi ezibushelelezi, ezinganamatheli zibalulekile — indawo yensimbi ehlanganiswe nengilazi enobulukhuni obungaphansi kuka-Ra 0.8 µm ivimbela udaka ukuba lunamathele emzimbeni futhi yenza ukuhlanza kube lula.
Izigaba zokwelashwa kwezinto eziphilayo: Amathangi okungenisa umoya nawama-bioreactor agcina izinqubo ze-activated sludge noma ze-biofilm. Lawa mathangi kufanele amelane nokugqwala kuphela, kodwa futhi nokushukunyiswa okungapheli, imithwalo yemishini yokuxuba, nokushintsha kwezinga lokushisa iminyaka eminingi yokusebenza okuqhubekayo.
2. Kungani Impahla Yethangi Inquma Isikhathi Sokuphila Sesikhungo Sokuhlanza Indle
Ukumelana nokugqwala kulo lonke uhla lwe-pH: Amakhemikhali endle ayengaqagelwa. Amathangi e-GFS ahlanganisa ungqimba lwe-vitreous enamel nensimbi ku-820–930°C, enza indawo engasebenzi, engenazimbotshana emelana nokugqwala kusukela ku-pH 1 kuya ku-pH 14 — ihlanganisa kokubili imikhiqizo ye-fermentation ene-asidi namakhemikhali okuhlanza ane-alkali.
Ubuqiniso obuqinisekisiwe bokwakheka: Imiklamo yamathangi eqinisekiswe ku-AWWA D103, ISO 28765 kanye ne-EN 1090 inika abanikazi bezitshalo ubufakazi obuhlolwayo bokuphepha kokwakheka, ukuthobela umthwalo womoya nokuzamazama komhlaba, kanye nokuqina kwemithungo — ihlolwe iphaneli ngephaneli ngokuhlolwa kwe-holiday engu-1500V DC.
Ukumiswa ngamamojula ngokuphazamiseka okuncane endaweni: Amaphaneli e-GFS aboshwayo amiswa ngamasistimu wokukhuphula ngamanzi ngaphandle kwama-cranes, ukushisela, noma ukuthela ukhonkolo. Izikhungo zokuhlanza amanzi zingakwazi ukunweba umthamo kamuva ngokumane zengeze amarings amaphaneli — inzuzo enkulu komasipala akhulayo.

Imibuzo Ejwayelekile (FAQ)
UMBUZO 1: Uyini ithangi lokuhlanza amanzi angcolile?
Ithangi lokuhlanza indle umthombo wokugcina nokucubungula esikhungweni sokuhlanza indle eligcina amanzi angcolile ngesikhathi sokulinganisa, ukuhlala, ukwelashwa kwebhayoloji nokucaciswa. Izitshalo zanamuhla zivame ukusebenzisa amathangi ensimbi ahlanganiswe nengilazi ehlanganiswe ngamabhawudi aklanyelwe i-AWWA D103 ne-ISO 28765 ukuze asebenze iminyaka engaphezu kwengu-30 ngokumelana nokugqwala.
UMBUZO 2: Kungani i-hydrogen sulfide iyinkinga enkulu kumathangi endle?
Igesi ye-H2S ekhiqizwa amagciwane angadingi umoya-mpilo iguquka ibe i-sulfuric acid ezindongeni zethangi nasezindaweni ezingaphezulu, igqwala ngokushesha insimbi ehlanganisiwe nokhonkolo. Ungqimba lwengilazi olungenayo ikhemikhali lwe-glass-fused-to-steel, oluqinisekisiwe nge-1500V DC, luvimba lokhu konke.
UMBUZO 3: Ithangi lokuhlanza indle lingaba likhulu kangakanani?
Amathangi e-GFS aboshiwe okokwelashwa kwendle ayakhiwa ngendlela eguquguqukayo futhi angakhula kusukela kumakhubhu amamitha ayishumi kuya ngaphezu kuka-30,000 m³ ethangini elilodwa — i-Center Enamel ilethe amathangi afinyelela ku-32,000 m³, okuwona thangi elikhulu kunawo wonke le-GFS elirekhodiwe.
Umbuzo 4: Ithangi lokwelashwa kwendle lihlala isikhathi esingakanani?
Ithangi lokwelapha indle eliqinisekisiwe le-GFS lihlinzeka ngempilo yokusebenza engaphezu kweminyaka engu-30 ngaphandle kokuphinda lihlanjululwe, uma kuqhathaniswa neminyaka engu-10–15 yensimbi ecwecweziwe enamekile kanye nezindleko ezinkulu zokulungisa imifantu kakhonkolo phakathi kweminyaka engu-25–35.
