Indlela Yokucacisa Igobolondo Lesihlungi Lemidiya, I-Underdrain kanye ne-Backwash
Igobolondo lesihlungi akulona ibhokisi elingenzi lutho; liyisembozo sengcindezi lapho imidiya, i-underdrain kanye ne-backwash kusebenza khona konke. Uma ulicacisa kabi, i-underdrain ayihambisani kahle noma igobolondo liyaphenduka.
Chaza igobolondo elizungeze izinto ezintathu: umthwalo wemidiya ewuthwalayo, i-underdrain ewusekelayo, kanye namasondo e-backwash okufanele iwavimbe.
Ukuchaza igobolondo lesihlungi kusho ukuchaza ukuma kwalo, izimo zomthwalo wesakhiwo, ukungena kwama-nozzle kanye nendawo yangaphakathi ukuze liqukathe ngendlela efanele imidiya yesihlungi, lisekele i-underdrain, futhi limelane nesimo se-backwash.
Izici Eziyisisekelo, Izingxenye Nezinhlobo
Isembozo semidiya: Umthamo wegobolondo kanye naphansi kufanele kuhambisane nokujula kwemidiya okucacisiwe (isihlabathi, i-anthracite, itshe elikhulu) kanye nesisindo sawo esigcwele, kube nendawo yokwengeza ngesikhathi se-backwash.
Ukusekelwa kwe-underdrain: Uphansi kanye nanoma yimaphi ama-nozzle noma ama-lateral kufanele kusekelwe ngendlela eqondile, ngoba ukungahambisani kahle kwe-underdrain konakalisa ukusatshalaliswa.
Isimo se-backwash: Izinga le-air-scour, izinga le-backwash yamanzi kanye nokulandelana kwazo kubeka umthwalo oguquguqukayo kanye nokukhipha umoya okudingekayo.
Ukufinyelela: Ama-manway nama-nozzle anobukhulu obufanele ukubeka imidiya, ukufaka i-underdrain kanye nokulungisa.
Izinhlelo Zokusebenza Nezimo Zokusetshenziswa
Kusetshenziswa lapho kwakhiwa izihlungi zesihlabathi esisheshayo, i-multimedia, i-activated-carbon noma izihlungi ezifanayo ezitshalweni zamanzi zikamasipala noma zezimboni, lapho igobolondo ne-hydraulics kwakhiwa njengento eyodwa.
Ukucatshangelwa Kwezobuchwepheshe
Qala emsebenzini we-hydraulic: izinga lamanzi okuhlanza emuva (ngokuvamile 8-15 m/h noma ngaphezulu kwezinye izinto zokuhlunga) kanye nezinga lomoya wokuhlanza kuchaza ukugcwala nokuphakama. Igobolondo kufanele ligcine lokhu kugcinwe ngaphandle kokuphambuka okuzodala ukuqhekeka kwama-coatings kamuva noma ukushintsha kwe-underdrain. Nikeza i-freeboard yokwanda kwezinto zokuhlunga (izinto zokuhlunga zingakhula nge-20-50% ngesikhathi sokuhlanza emuva). Linganisa ama-nozzles nama-manways ukuze kubekwe izinto zokuhlunga nokuhlanganiswa kwe-underdrain, futhi ucacise indawo yangaphakathi yomsebenzi wamakhemikhali nokuguguleka.
Igobolondo elizinzile ngokwesilinganiso, elihlanzekayo (njenge-GFS) livikela ukuxhumana kwe-underdrain kanye nekhwalithi ye-filtrate phakathi namashumi eminyaka emijikelezo.
Umhlahlandlela Wokuqhathanisa Nokukhetha
Okokufaka kwe-Spec | Ama-drive | Inani elijwayelekile / inothi |
Ukujula kwemidiya | Phansi kanye nevolumu | Izendlalelo zesihlabathi/i-anthracite/amatshe amancane |
Umthwalo wemidiya egcwele | Ukwakhiwa kwaphansi | Amaningi t/m3 uma emanzi |
Izinga lamanzi okuhlanza emuva | Ukugqashuka, ukukhipha umoya | Ngokuvamile 8-15+ m/h |
Izinga lokuhlanza ngomoya | Ukukhuphuka, ukuhlanekezela | Kuncike ekulandelaneni |
Ukukhula kwe-media | I-freeboard | 20-50% ngesikhathi sokugeza |
Izinqubo Ezinhle Kakhulu Nokuthi Ungakhetha Kanjani
Qala ngokuxazulula umklamo wenqubo yokuhlunga, bese ucacisa igobolondo kusukela esimweni sokuhlanza emuva, umthwalo wezinto zokuhlunga ezigcwele kanye nezidingo zokusekelwa kwe-underdrain. Nikeza i-freeboard yokwanda, linganisa ukufinyelela kwezinto zokuhlunga nomsebenzi we-underdrain, futhi ucacise indawo yangaphakathi yomsebenzi wamakhemikhali nokuguguleka.
Cacisa igobolondo lesihlungi njengesembozo semidiya, i-underdrain kanye ne-backwash ndawonye. Yenza umsebenzi we-hydraulic ngendlela efanele futhi igobolondo lizogcina i-underdrain iqinile futhi limelane nawo wonke umjikelezo.
Imibuzo Evame Ukubuzwa (FAQ)
Igobolondo lesihlungi liqukethe ini ngempela?
Liqukethe imidiya (isihlabathi/i-anthracite/itshe), lisekela i-underdrain, futhi kufanele limelane nokugcwala kwe-backwash kanye ne-vacuum. Liyisakhiwo esiyisembozo lapho ama-hydraulics asebenza khona, hhayi ibhokisi elingenzi lutho.
Ingakanani i-freeboard edingwa isihlungi?
Kwanele ukunwetshwa kwemidiya ngesikhathi sokugeza emuva, ngokuvamile u-20-50% wokujula kwemidiya kuye ngezinga nemidiya. Okuncane kakhulu kuvumela imidiya ukuthi ikhishwe; okuningi kakhulu kumosha umthamo.
Kungani ukugeza emuva kufanele kube kusikhwama somgogodla?
Ukuhlanza komoya nokuhlehla kwamanzi ngezinga eliphezulu kudala ukugcwala, ukuphakama nokucindezela okuhlukile okungahlanekisa noma kugobe igobolondo elingaklanyelwe lokho, kamuva kuqhekeze izindwangu futhi kungahambisani kahle nomsele wangaphansi.
Iyiphi indawo yangaphakathi efanele igobolondo lesihlungi?
Indawo ebushelelezi, engasebenzi, ehlanzekayo (njenge-GFS) imelana nokugezwa ngamakhemikhali nokuhuzuka kwezinto zokuxuba futhi igwema ukungcola kwe-biofilm okonakalisa i-filtrate, ikakhulukazi emashumini eminyaka yemijikelezo.
Ingabe imithwalo ye-underdrain isingathwa kanjani?
Uphansi nanoma yimiphi imibhobho noma ama-laterals kufanele kusekelwe ngokweqiniso futhi kwakhelwe isisindo se-media egcwele kanye nokukhuphuka kokuhlanza emuva, ngoba ukungahambisani kahle kwe-underdrain konakalisa ukusabalalisa.
