Uyini Ithangi Lokugcina I-Leachate? Ukuklanywa Kwezindawo Zokulahla Imfucumfucu Nokukhethwa Kwezinto
Ithangi lokugcina i-leachate liyisitsha sokugcina esibamba i-leachate yendawo yokulahla imfucumfucu — uketshezi olungcolile kakhulu olwakheka lapho imvula ingena emfucumfucwini — ngaphambi kokuba lwelashwe, liphinde lijikeleziswe noma luthuthwe lisiwe kwenye indawo. Ngenxa yokuthi amakhemikhali e-leachate ashintshashintsha kuwo wonke amazinga e-pH, amathangi ensimbi ahlanganisiwe ane-GFS (glass-fused-to-steel) anezihlanganisi eziqinisekisiwe nge-1500V ayikhetho ehamba phambili.
I-leachate ngokungangabazeki iwuketshezi olulimaza kakhulu ithangi elingacelwa ukuthi ligcine: izigidi zemiligramu nge-litha ye-COD, i-ammonia ephezulu, ama-chloride, izinsimbi ezisindayo kanye ne-pH engashintsha isuke kokune-asidi iye kokune-alkali eqinile njengoba indawo yokulahla imfucumfucu iguga. Insimbi emboziwe nokhonkolo kokubili kuyonakala; ukuvuza kuyizehlakalo zemvelo. Ngakho-ke, ukukhethwa kwezinto kuyisinqumo sokuthobela imithetho, hhayi nje isinqumo sokuthenga.
1. Iyini Indima Yethangi Lokugcina Amanzi Acwiliswayo (Leachate) Emgwaqweni Wokulahla Imfucumfucu?
Isivimbeli phakathi kokukhiqizwa nokwelashwa: Amanzi acwiliswayo akhiqizwa njalo ngemvula kodwa elashwa noma athuthwe ngamaqoqo. Ithangi lokugcina lilinganisa ukugeleza nomthwalo, livikele ukwelashwa okulandelayo — kungaba i-RO endaweni, ukuhwamuka, ukuphinda kusetshenziswe noma ukuthuthwa ngamathangi ukuya esikhungweni sikamasipala.
Ukulinganisa ukwakheka kwamakhemikhali okushintshashintshayo: Amanzi acwiliswayo amancane amuncu futhi ane-COD ephezulu; amanzi acwiliswayo avuthiwe aba ne-alkali futhi agcwele i-ammonia. Ithangi lihlanganisa yomibili imifudlana ukuze ukwelashwa kuthole ukudla okubikezelwayo, kudinga into ekwazi ukumelana nalo lonke uhla lwe-pH.
Ukuvinjelwa okuhambisana nemithetho: Abalawuli badinga ubufakazi bokuqina. Amathangi e-GFS acwiliswayo ahlolwa iphaneli ngephaneli nge-1500V DC futhi aklanyelwe ukuhambisana ne-AWWA D103 ne-ISO 28765, anezinketho zodonga oluphindwe kabili noma ama-bunded ukunikeza ukuvinjelwa kwesibili.
2. Ukucacisa Ithangi Lokugcina Amanzi Acwiliswayo Eliphila Ngale Kwesikhathi Sokusebenza Kwenkundla Yokulahla Imfucumfucu
Ukuzivikela okugcwele ekugqwaleni: I-GFS enamel ehlanganiswe nensimbi ku-820–930°C imelana ne-pH 1–14 leachate, ama-chloride, ama-solvent kanye ne-ammonia ngaphandle kokuba khona ulwelwesi oluzokhumuka noma oludinga ukuphinde lufakwe — indlela yokwehluleka eqeda amathangi e-leachate enziwe ngensimbi ehlanganisiwe phakathi kweminyaka emi-5 kuya kweyi-10.
Imiklamo engangeni moya futhi evalekile: I-leachate ikhiqiza i-biogas enephunga. Amathangi e-GFS abhuntshisiwe amukela izembozo ezingangeni moya, izinsimbi zokulinganisa izinga kanye nama-nozzle okujikeleza, aqukethe ukukhishwa kwemoya futhi enze ukujikeleza kwe-leachate okusheshisa ukuzinza kwemfucuza.
Umthamo oyimojula olandela indawo yokulahla imfucuza: Njengoba indawo ikhula, amaringi amaphaneli aboshwe ngamabhawudi anweba umthamo wethangi emasontweni; ngemva kokuvalwa, amathangi angathuthwa kwezinye izindawo — okungenzeki ngokhonkolo. Lokhu kuguquguquka kuvikela utshalomali empilweni yendawo yokulahla imfucuza yeminyaka engu-30.
I-Matrix Yokuqhathanisa: Izinto Zethangi Lokugcina I-Leachate
Ipharamitha Yokuhlola | Ithangi Le-GFS Loketshezi Olungcolile | Ichibi Elinomugqa We-HDPE | Ithangi Lensimbi Elimbonyiwe |
pH 1–14 and chloride resistance | Kuhle kakhulu — i-enamel engasebenzi | I-liner enhle, ingozi yokubhoboza/i-UV | Kubi — ukuhlaselwa kokumboza |

Ukuthutha / ukunwetshwa komthamo | Amaphaneli aboshwe ngamabhawudi — ukuguquguquka okugcwele | Izinkinga zokushintshwa kwe-liner | Akusebenzeki |
Imibuzo Ejwayelekile (FAQ)
UMBUZO 1: Liyini ithangi lokugcina i-leachate?
Ithangi lokugcina uketshezi olungcolile ligcina amanzi angcolile akhishwa emgqonyeni wemfucuza ngaphambi kokwelashwa noma kokulahlwa. Amathangi e-GFS oketshezi olungcolile amelana nawo wonke amazinga e-pH 1–14 wekhemistri yoketshezi olungcolile iminyaka engaphezu kwengu-30, wonke umthungo uqinisekiswa ukuhlolwa kwe-1500V DC holiday ngokwe-AWWA D103 ne-ISO 28765.
UMBUZO 2: Kungani uketshezi olungcolile lulimaza kakhulu amathangi?
Uketshezi olungcolile luhlanganisa i-COD ephezulu, i-ammonia, ama-chloride nezinsimbi ezisindayo kanye ne-pH eshintsha ukusuka ku-asidi (imfucuza emisha) kuya ku-alkaline (imfucuza evuthiwe). Lokhu kuhlasela izinto zokumboza eziphilayo nokhonkolo ongenawo amanzi; izithiyo ezingasebenzi njenge-glasi enamel ehlanganisiwe kuphela ezingasinda ngokuthembekile.
UMBUZO 3: Ithangi loketshezi olungcolile likalwa kanjani?
Isisekelo somthamo kusekelwe ekukhiqizweni okulindelekile koketshezi olungcolile — imvula phezu kwendawo egcwele — iphindwe ngezinsuku zokugcina ezidingekayo, kanye nezehlakalo zeziphepho. Amathangi e-GFS amamojula asuka ku-100 m³ kuya ku-32,000 m³ avumela ukunwetshwa ngezigaba njengoba indawo yemfucuza ikhula.
Umbuzo 4: Ingabe amathangi okugcina i-leachate angamboza?
Yebo. Ophahla abhuntshisiwe abangangeni moya baqukatha amaphunga negesi yokulahla imfucuza, benze amalophu okujikeleza, futhi bavimbe ukungena kwemvula — okwenza uphahla lube yindlela yokulawula imvelo kanye nethuluzi lokulawula umthamo.
