Amathangi Okuhlalisela Amanzi Angcolile Ensimbi Engagqwali: Umhlahlandlela Wobunjiniyela Nokuklama
Ezindaweni zanamuhla zokuhlanza amanzi angcolile ezimbonini nasezindaweni zomasipala (WWTPs), ukwehlukaniswa okuphumelelayo kokuqinile noketshezi kubalulekile ngaphambi kokuba amanzi ahlungwe kakhulu, elashwe ngamabhaktheriya, noma akhishwe. Amathangi okuhlala amanzi angcolile ensimbi engagqwali—avame ukubizwa ngama-clarifiers noma amathangi okudephozela—asebenza njengomgogodla walezi zinqubo zokwehlukanisa. Ngokuhlanganisa umklamo oqinile wemishini nokumelana nokugqwala okuphezulu kwezinhlobo zensimbi engagqwali ye-austenitic (ezifana ne-AISI 304 ne-316L), lezi zinhlelo ziletha ukuphila isikhathi eside, ukuqina kwesakhiwo, nokugcina ubumsulwa ezindaweni ezinamakhemikhali anamandla.
1. Izimiso Eziyisisekelo Zokusebenza Zamathangi Okuhlalisela
Ukuhlalisela ekwelashweni kwamanzi angcolile kuncike kumandla adonsela phansi alula ukuze kuhlukaniswe izinhlayiya eziqinile (TSS) ezigabeni eziwuketshezi. Lapho amanzi angcolile angalungisiwe noma aselungiswa kancane engena ethangini lokuhlalisela, ijubane lokugeleza liyancipha kakhulu, okudala izimo zokugeleza okuhle ukuze izinhlayiya eziqinile eziminyene zihlale phansi kuyilapho amanzi acwengekile ephuma phezulu.
● Indawo Yokungenisa: Amandla okungenayo asakazwa kusetshenziswa ama-baffle angaphakathi ukuze kuncishiswe ukuphazamiseka nokusabalalisa imithwalo ye-hydraulic ngokulinganayo.
● Indawo Yokuhlalisela: Ngaphansi kwezimo zokuthula, izinhlayiya ezimisiwe zihamba ziye phansi ngokusekelwe ejubaneni lazo lokuhlalisela, lithonywa ubukhulu bezinhlayiya, ukuminyana, nokujiya kwamanzi.
● Indawo Yokudaka: Izinto eziqinile eziqongelelayo (i-primary noma i-secondary sludge) ziqongelela phansi ethangini ukuze zikhishwe ngokuqhubekayo noma ngezikhathi ezithile.
● Indawo Yokukhipha Amanzi: Amanzi ahlanzekile, acwengekile adlula emigwaqweni elungisekayo ukuze aye ekubulaleni amagciwane noma ekuhlanzweni okwengeziwe.
2. Izinzuzo Zempahla: Kungani Insimbi Engagqwali?
Nakuba ukhonkolo nensimbi yekhabhoni kuyizinto zokwakha ezijwayelekile zamachibi okuhlalisa, insimbi engagqwali inikeza izinzuzo ezihlukile zokusebenza namakhemikhali, ikakhulukazi emikhakheni yezimboni ekhethekile:
Ipharamitha Yokuhlola | Insimbi Engagqwali (304/316L) | Insimbi Yekhabhoni Ependiwe | Izitsha Zikakhonkolo |
Ukumelana Nokugqwala | Kuhle Kakhulu (Ungqimba lwe-chromium oxide olungasebenzi) | Okumaphakathi (Kudinga ukuphinda kupendwe ngezikhathi ezithile) | Isengenwa kalula ukuhlaselwa ngamanzi ane-asidi |
Ukubushelelezi Kobuso | Phezulu (Kuvimbela i-biofilm nokunamathela kwe-sludge) | Emaphakathi (Iwohloka ngokuhamba kwesikhathi) | Ephansi (Ukungena kwamanzi kukhuthaza ukunqwabelana kwezinto) |
Ukuguquguquka Kokufakwa | Okuphezulu (Amayunithi amodula noma afakwa ngaphambilini) | Okuphezulu (Kushiselwa endaweni) | Okuphansi (Ingqalasizinda yokwakha emisiwe) |
Isikhathi Esilindelekile Sokuphila | Iminyaka engu-30 kuya kwengu-50+ | Iminyaka engu-15 kuya kwengu-25 | Iminyaka engu-40+ (Ngokuya ngokulungiswa kwemifantu) |
Izindleko Zokunakekela | Okuncane (Akukho ukufakwa kwangaphakathi okudingekayo) | Okuphezulu (Ukuhlolwa kokugqwala njalo) | Okulingene (Ukuvala amalunga nokulungisa imifantu) |
3. Ukucushwa Okubalulekile Kokuklama
Amathangi okuhlalisa ensimbi engagqwali enziwa ngezindlela ezahlukene ukuze ahambisane nezindawo ezithile kanye namandla okuhambisa amanzi:
● Ama-Clarifier Ayindilinga: Anama-drive amaphakathi, izingalo ezihlanekezelayo zokukhuhla udaka, kanye nemisele yokuphuma emaphethelweni. Afanele izicelo zomasipala nezimboni eziphakathi nendawo kuya kwezinkulu.
● Amasilo Aqondile / Amathangi Angeyinkimbinkimbi: Amathangi amade angezansi kwe-conical (anjengamasilo ezimboni "C-Series") avumela ukujiya okusheshayo ngomhlaba kanye nokukhishwa kukadaka kalula ngaphandle kwemishini eyinkimbinkimbi yokukhuhla.
● Ama-Lamella / Ama-Settler Anamapulangwe Atshekile: Ahlanganisa amapulangwe angaphakathi atshekile ngaphakathi kwekhava lensimbi engagqwali, ephindaphinda indawo yokuhlalisa esebenzayo futhi anciphise indawo edingekayo ngamaphesenti angama-80 uma kuqhathaniswa namachibi okuhlalisa ajwayelekile.
4. Izicelo Zezimboni
Amathangi okuhlalisa ensimbi engagqwali asetshenziswa emikhakheni ehlukahlukene lapho amakhemikhali abolayo, amazinga e-pH ashintshashintshayo, noma amazinga aqinile enhlanzeko enza ukuthi insimbi evamile noma ukhonkolo kungafaneleki:
● Ukucubungula Amakhemikhali Nemithi: Ukuphatha amanzi angcolile agcwele ama-solvent anamandla, ama-asidi, noma izinhlanganisela ezinosawoti omningi.
● Ukukhiqiza Ukudla Neziphuzo: Ukwelapha amanzi angcolile anomthwalo ophezulu wezinto eziphilayo aqukethe amafutha, uwoyela, namafutha agxilile (FOG).
● Izimayini Nokucubungula Amaminerali: Ukuphatha izingxube zamaminerali ezilumelayo kanye namanzi okugeza ama-tailings anokungafihleki okuphezulu.
● Ukuqedwa Kwensimbi Nokufakwa Kwe-Electroplating: Ukususa ama-heavy metal hydroxides ngemva kwezinqubo ze-chemical precipitation.
Imibuzo Ejwayelekile (FAQ)
Umbuzo: Kungani ukhetha insimbi engagqwali (stainless steel) kunekhonkolo noma insimbi ye-carbon kumathangi okuhlala amanzi angcolile?
Impendulo: Insimbi engagqwali inikeza ukumelana nokugqwala kwamakhemikhali namanzi ane-asidi ngokwemvelo, ngaphandle kwesidingo se-epoxy coatings ezilula. Ingaphakathi layo elibushelelezi, elingenazimbotshana livimbela ukunqwabelana kwe-sludge nokukhula kwamagciwane, kwehlisa izindleko zokunakekela zesikhathi eside futhi kwandisa impilo yokusebenza.
Umbuzo: Uyini umehluko phakathi kwe-304 ne-316L insimbi engagqwali ekusetshenzisweni kwamanzi angcolile?
Impendulo: I-AISI 304 insimbi engagqwali ilungele amanzi angcolile ajwayelekile omasipala nawokukhanya kwezimboni. I-AISI 316L iqukethe i-molybdenum ne-carbon ephansi kakhulu, enikeza ukumelana okuthuthukisiwe nama-chlorides, ukugqwala kwe-pitting, nokugqwala kwe-intergranular ezindaweni ezinamakhemikhali anamandla noma zasolwandle.
Q: Ama-lamella packs awathuthukisa kanjani ukusebenza kahle kwamathangi okuhlala ensimbi engagqwali?
A: Ama-lamella plate packs ethula izindawo eziyizingqimba ezithambekele ezikhulisa kakhulu indawo yokuhlala ephumelelayo ngaphakathi komthamo omncane. Lokhu kusheshisa ukuhlala kwezinhlayiya, kunciphisa isikhathi sokugcinwa kwamanzi, futhi kufeza ukonga indawo okungafika ku-80% uma kuqhathaniswa nezitsha zokuhlala ezivulekile zendabuko.
Q: Ingabe amathangi okuhlala ensimbi engagqwali adinga ukupendwa noma ukufakwa kolwelwesi ngaphakathi?
A: Ngokuvamile, cha. Ngokungafani namathangi ensimbi yekhabhoni adinga upende ovikelayo noma ulwelwesi lwe-epoxy ukuvimbela ukugqwala, insimbi engagqwali incike kungqimba lwe-chromium oxide oluzilungisayo oluhlala lingasebenzi uma luthintwa namanzi ahlanziwe noma aluhlaza.
