Amathangi Okugcina Udaka
Ezindaweni zokuhlanza amanzi angcolile emadolobheni (WWTPs), ezindaweni zokuhlanza imikhiqizo yezimboni, kanye nasezindaweni zokugaya izinto ngaphandle komoya, ukuphathwa kwezimbiza kubonisa indlela eyinkimbinkimbi yokubiza ukusebenza (OPEX). Izimbiza zokuhlala zokuqala, izimbiza ezisebenzayo zesibili, kanye nezimbiza ezihlanziweyo ziyahlukahluka kakhulu ngokuqina, ukuminyana, kanye nezinga lokugeleza. Ukugwema ukushaqeka okukhulu komthamo wamanzi, ukuqinisa ukuminyana kwezinto eziqinile, kanye nokuqinisekisa ukudla okuqhubekayo, okufanayo kumishini yokukhipha amanzi (njengamaphasishi esihlungi, ama-centrifuge, noma ama-screw press), imigqa yokucubungula idinga ithangi elizinikezele lokubeka izimbiza.
Esikhundleni sokusebenza njengesikhungo esilula, esingasebenzi, ithangi lokubamba udaka lisebenza njengesishintshi esinamandla kakhulu se-rheological nesamakhemikhali. Isakhiwo kumele siqukethe uketshezi olunamandla aphezulu, olungelona i-Newtonian, simelane nokuguguleka okunamandla okubangelwa amakhemikhali namagciwane, futhi senze kube lula ukuqhubeka nokuhlanganisa ukuze kuvinjelwe ukwahlukaniswa kwezinto eziqinile.
Kubasizi be-EPC bomphakathi, abaphathi bezitshalo, kanye nabaphathi bezinsiza zemvelo, ukukhetha umklamo wesakhiwo nobunjiniyela bezinto ezisetshenziswa ethangini lokubamba udaka akushiyi ndawo yamaphutha. Ngezansi kunesakhiwo sobuchwepheshe esingokwemvelo, esisekelwe kudatha, esiklanyelwe ukusiza amaqembu okuthenga ukuthi ahlolisise futhi akhe uhlelo lwezinga lomhlaba lokubamba udaka.
1. I-Sludge Rheology: Ukuphatha Uketshezi Olungelona i-Newtonian kanye Nokuhlanganisa
Udlela wokungcola kwamanzi awuziphathi njengamanzi avamile. Uma ukugcwala kwezinto ezingagxili (TSS) kudlula ku-3% kuye ku-7%, udlela luguquka lube uketshezi olungelona i-Newtonian, oluthixotropic, lubonise ukuqina okuphezulu okubonakalayo kanye nokucindezeleka okucacile okumele kunqotshwe ukuze kuqale ukuhamba.
Le rheology ehlukile ifuna ubunjiniyela obunembayo bemishini kanye ne-hydraulic ngaphakathi kwethangi lokubhafa:
● Ukuvimbela Ukuhlukaniswa Nokucindezela: Uma udlela uhlala unganyakazi, izinhlayiya ezisindayo ezingokwemvelo nezingezona ezingokwemvelo ziyaqala ukuhlala phansi, zicindezeleke phansi kwethangi. Lokhu kucindezela kungadala ukuthi amaphampu okukhipha angasebenzi futhi kubangele ukungalingani kwezakhiwo endaweni ethile.
● Izindlela Zokuxuba Eziyimpumelelo: Amathangi okugcina ama-sludge e-Elite ahlanganisa ama-agitator we-hydrofoil aqine kakhulu, aphansi kancane, noma ama-pump okuxuba ama-chopper akhethekile. Lezi zinhlelo zakhelwe ukusebenzisa i-fluid shear efanayo, ukwephula isakhiwo se-gel ye-thixotropic ye-sludge, ukugcina ukuhlanganiswa okuphelele, nokuqinisekisa ukuminyana okufanayo kokudla okuqinile kumasekethe okukhipha amanzi angaphansi.
2. Isayensi Yezinto Ezithuthukisiwe: Ukunqoba i-MIC Enzima Kakhulu Yesikhala
Indawo engaphakathi ethangini lokubamba udaka iyindawo enobuthi kakhulu kwezobunjiniyela bemvelo. Ngenkathi indawo engamanzi igcina imvelo ye-acidic-to-neutral, isikhala esivaliwe ngaphezu komugqa wamanzi sibhekana nezingozi ezinkulu zokugqwala ezibangelwa yi-Microbial-Induced Corrosion (MIC).
● Ukuguquka Kwegesi ye-H2S: Izindawo ezingenawo-oxygen ngaphakathi kodaka olujiyile ziqhubeka nokukhipha igesi ye-hydrogen sulfide (H2S) esikhundleni esivaliwe.
● Ukukhiqizwa Kwama-asidi E-sulfuric E-biogenic: Esiqongweni esinomswakama, amagciwane acweba i-sulfur (i-Thiobacillus) adla igesi le-H2S nomswakama wokugayeka kokudla, akhiqize i-sulfuric acid (H2SO4) enokugxilisa kakhulu. Le acid ye-biogenic igugisa kakhulu ukhonkolo ongavikelekile, ibangele ukugqabhuka okukhulu kwesakhiwo, futhi ngokushesha yenze amabhamuza emidwebeni yomhlaba esetshenziswa ngoketshezi, okuholela ekuhlulekeni kwensimbi yesakhiwo.
Ukuze kuhlale kulesi simo, ingqalasizinda yesimanje ichaza amathangi aboshwe nge-Glass-Fused-to-Steel (GFS) njengezinga lomhlaba wonke lamachibi okubhafa udaka:
● I-GFS Barrier Advantage: Amaphaneli ensimbi yekhabhoni afakwa imboni nge-proprietary glass frit futhi ashunqulwa kuhhavini oluzenzakalelayo ezingeni lokushisa elisuka ku-820°C liye ku-930°C. Ukuhlanganiswa kwamakhemikhali, kwamajoyina okuhlanganisa ukuqina kwengilazi, isiphetho se-ceramic esingenawo umoya sihlanganisela eshidi lensimbi. Ngokuqina okuphelele kwe-6.0 Mohs surface hardness kanye nokubekezelelana okubanzi kwe-pH kusuka ku-1.0 kuye ku-14.0, i-GFS ayithinteki nhlobo yi-biogenic sulfuric acid, iqinisekisa iminyaka engu-30+ yokuphila kokusebenza okungadingi ukugcinwa.
3. Umklamo Wesakhiwo: Ukumelana Namaphethini Omthwalo Ongashintshi
Ngenxa yokuthi amathangi okugcina udaka (sludge buffer tanks) athola ukugeleza okuqhubekayo nokukhipha okusheshayo okuhambisana namashejuli okukhipha amanzi, ingaphandle leli thangi libhekana nengcindezi enkulu yomzimba:
● Ukulayisha ngokuguquguquka koketshezi: Izinguquko eziqhubekayo ezingeni loketshezi zibeka izixhumanisi zamaphaneli ekukhathaleni okukhulu okujikelezayo.
● Ukwakheka kwamaphaneli acijile: Amathangi akwa-Elite modular bolted asebenzisa ukwakheka okucijile. Amaphaneli ensimbi ashubile, asindayo abekwa emaringeni aphansi ukuze athole ingcindezi enkulu yokwelula (hoop tensile stresses) ebangelwa udaka oluminyene, olunesisindo esikhulu, kanti amaphaneli alungiswe kahle enza amaringi aphezulu—kwandisa ukonga izinto ngaphandle kokudela izinto zokuphepha.
● Ukubopha ngenxa yokuqubuka komhlaba nomoya: Izinhlelo ezinkulu zokugcina zidinga ukubopha ngezindandatho eziqinile zomoya namabrakethi okubopha ngenxa yokuqubuka komhlaba ahambisana namazinga afana ne-AWWA D103-09 ne-ISO 28765 ukuze zimelane nezingcindezi zokujikeleza ezibangelwa imvelo.
4. Ukuqinisekiswa Kwekhwalithi Okujwayelekile: Ukuhlolwa Kweholide Okungu-1500V+
Umenzi ohamba phambili wokugcina amanzi angcolile akaze ashiye ukulawulwa kwekhwalithi yokugqoka ngokubuka nje noma ukukhetha amasampula angahleliwe. Ngoba umfantu owodwa ongabonakali noma imbobo kungadala ukuthi insimbi engaphansi ibe sezimweni zamakhemikhali ezinolaka ezindaweni zokuhlanza amanzi—kubangele ukugqwala okusheshayo ngaphansi kwefilimu nokuncipha kwezindonga ezakhiweni—abakhiqizi abaphezulu banquma inqubo yokuhlola eyenziwa efrijini engadali monakalo eyi-100%.
● Ukuhlolwa ngogesi ophakeme: Ochwepheshe befekthri badlulisa ugesi okhethekile ophakeme—okulinganiswe ngokuqinile phakathi kuka-1,500V no-1,800V—kuwo wonke umhlaba wephaneli ngayinye ekhiqizwayo.
● Izinkinga Zokungabi Nokwethembeka: Uma okwamanje kutholwa noma yikuphi ukungabikho okuncane noma ukuphazamiseka emgqeni wokuvikela ingilazi noma ungqimba lwe-polymer oluhlanganisiwe, iphaneli iyalahlwa ngokushesha. Lesi sihloko esiqinile siqinisekisa umgoqo ongenakuvuza ofakazelwe efektri ngo-100% ngaphambi kokuthunyelwa, siqeda ubungozi bokwehluleka ngesikhathi sokufakwa endaweni.
