Amathangi Okugcina Amanzi Acwiliswayo (Landfill Leachate): Ukuvikelwa Kokugqwala Kwe-Leachate Enobudlova
I-Leachate ingelinye lamakhemikhali ayingozi kakhulu kwezobunjiniyela bezemvelo: i-COD ephezulu, i-ammonia, izinsimbi ezisindayo, ama-chloride kanye ne-hydrogen sulfide eshintsha i-pH ngokungaqaguleki njengoba indawo yokulahla imfucuza iguga. Amathangi ahluleka ukuyimelana adala izingozi zokuthobela imithetho nokungcola.
Ithangi lokugcina uketshezi oluvuza emgqonyeni wokulahla imfucuza (landfill leachate) umkhumbi ovikelwe ukugqwala ogcina uketshezi phakathi kokuqoqa nokwelashwa, olwakhiwe ngokwe-AWWA D103 kanye ne-ISO 28765. Ukwakhiwa kwe-Glass-fused-to-steel (GFS) nge-enamel ye-pH 1–14 kanye nokuhlolwa kwe-holiday ye-1500V DC kunikeza iminyaka engaphezu kwengu-30 yokusebenza kulomsebenzi onzima.
Kungani Uketshezi Oluvuza Lubanga Kangaka Emathangini Okugcina?
Ukungazinzi kwe-pH: uketshezi oluvuza olusha lune-asidi (pH 4–6), uketshezi oluvuza oludala luphenduka i-alkaline (pH 7–9), futhi izimo ziyashintsha ngemvula nangeminyaka yendawo yokulahla imfucuza.
Ukuhlaselwa kwamakhemikhali: ama-chloride, ama-sulfate ne-ammonia ahlasela insimbi nokhonkolo; i-H2S yakha i-asidi egqwala endaweni yegesi.
I-COD nezinto eziphilayo: umthwalo ophezulu wezinto eziphilayo uqhuba umsebenzi webhayoloji osheshisa ukucekelwa phansi kokhonkolo nokugqokwa.
Ukugqokwa: izinto eziqinile ezimisiwe namatshe amancane kugqiba izinto zokugqoka ezithambile.
I-GFS Ivikela Kanjani Ithangi Lokugcina Uketshezi Oluvuza?
Ichemistry yobubanzi obugcwele: i-enamel ehlanganisiwe imelana ne-pH 1–14, ihlanganisa kokubili i-leachate encane ene-asidi nendala ene-alkali ngaphandle kokushintsha i-liner.
Ukuvikelwa kwezindawo ezimbili: ungqimba olufanayo olungenasabelo luvikela izindawo ezingaphansi kwamanzi kanye nendawo yegesi ye-H2S ejiyile.
Ubuqiniso obuqinisekisiwe: wonke amaphaneli namathambo ahlolwa nge-1500V DC holiday-test, okunikeza ukumbozwa okubhalwe phansi okungenazo izimbobo.
Ukumelana nokugqokwa: i-vitreous enamel ku-6.0 Mohs imelana ne-leachate egcwele izinto eziqinile.
Amathangi Okugcina I-Leachate Akhiwa Kanjani?
Izindinganiso: i-AWWA D103 yokwakheka kwesakhiwo kanye ne-ISO 28765 yekhwalithi ye-enamel; ukuvinjelwa kwesibili kanye nokutholwa kokuvuza ngokwemithetho yendawo.
Kuhlanganisa: Uphahla lwe-GFS noma lwe-aluminium dome lulawula iphunga, ukungena kwemvula kanye nokukhishwa kwegesi.
Ubukhulu: Amathangi asukela kumayunithi amancane okugcina kuya kufika ku-10,392 m³+ ukufakwa, anezindawo ezibiyelwe lapho kudingeka khona.
Okokongeza: Imishini yokuxuba, izilinganiso zamazinga, amachweba okuthatha amasampula kanye nemibhobho yokukhipha igesi evikelwe emlilweni kuqedela uhlelo.

Upharamitha Wokuhlola | Insimbi ye-GFS | Ukongkolo + I-Liner | Insimbi Emboziwe Eshiselwe | I-HDPE |
Ukumelana nobubanzi be-pH | i-pH 1–14 | Kuncike ku-liner | Kuncike ekumbozeni | Kuhle |
Ukumelana ne-H2S endaweni yegesi | Kuhle kakhulu | Kubi | Okumaphakathi | Kuhle |
Ukumelana nokugqokwa (abrasion) | 6.0 Mohs | Kuhle | Kubi | Okumaphakathi |
Isikhathi sokusebenza | Iminyaka engu-30+ | Iminyaka engu-20–30 | Iminyaka engu-10–20 | Iminyaka engu-10–15 |
Ukuqinisekiswa kwekhwalithi | I-1500V ngephaneli ngalinye | I-QC yokwakha | Kuncike endaweni | Ukuhlolwa komthungo |
Amathangi okugcina amanzi acwiliswayo (leachate) endaweni yokulahla imfucuza aphila noma afa ngokuvikelwa kokugqwala — i-GFS enamel efakwe ngokuncibilikile imelana ne-pH 1–14, ivikela ku-H2S futhi iqinisekiswe nge-1500V, okwenza kube ukukhetha okuzenzakalelayo kulabo abasebenza ezindaweni zokulahla imfucuza abangakwazi ukubhekana nokwehluleka kwesibili.
Imibuzo Ejwayelekile (FAQ)
Umbuzo 1: Liyini ithangi lokugcina amanzi acwiliswayo endaweni yokulahla imfucuza?
Umkhumbi ovikelwe ekugqwaleni ogcina amanzi acwiliswayo phakathi kokuqoqwa nokwelashwa. Izinhlobo ze-GFS — i-enamel encibilikiswe ensimbi ngezinga lokushisa elingu-820–930°C, yakhelwe ngokwe-AWWA D103 ne-ISO 28765 — imelana ne-pH 1–14 iminyaka engaphezu kwengu-30.
Umbuzo 2: Kungani amanzi acwiliswayo egqwala amathangi?
I-Leachate ithwala ama-chloride, ama-sulfate, i-ammonia, i-H2S kanye ne-pH engazinzile (4–9) ehlasela insimbi, ukhonkolo kanye nokugoqwa — kokubili kuketshezi naku-condensate gas zone. I-Fused enamel imelana nobubanzi obugcwele be-pH kanye ne-H2S.
UMBUZO 3: Yisiphi isayizi lethangi le-leachate elijwayelekile?
Amathangi e-Leachate asukela kumathangi amancane e-buffer kuya kuma-installation angaphezu kuka-10,392 m³+, alinganiswa ngemvula, inani lemfucuza kanye namandla okwelapha. Amathangi e-GFS ahlanganisiwe anda ngokwe-modular njengoba izigaba zokulahla udoti zikhula.
UMBUZO 4: Yiziphi izindinganiso ezisebenza emathangini okugcina i-leachate?
I-AWWA D103 ihlanganisa ukwakheka kwemiklamo yamathangi aboshwe ngamabhawodi; i-ISO 28765 ihlanganisa ikhwalithi yokumboza ngophelethi; imithetho yezemvelo ilawula ukuvinjelwa kwesibili, ukutholwa kokuvuza kanye nokulawulwa kwegesi.
