Ithangi Lodaka Kufanele Lixutshwe Futhi Lithululwe Kanjani
Kwadalwa ngo Ngokwamukisa
Indlela Itanki Lodaka Okufanele Lixutshwe Futhi Likhishwe Ngayo
Udaka aluwamanzi. Okuqukethwe kwayo okuphezulu kwe-solids kushintsha indlela oyigcina ngayo ifana nokuthi uyikhipha kanjani ngaphandle kokulimaza itanki noma abantu abakwenzayo.
Xuba udaka ngama-submersible noma ama-jet mixer alinganiswe ne-rheology yalo, futhi ulukhiphe nge-drain yaphansi, i-pump-out noma uhlelo lwe-rake oluklanyelwe ama-solids aphezulu, ngokuphepha okuqinile kwendawo evinjelwe.
Ukuxutshwa nokukhishwa kwenkunkuma kuhlanganisa imishini nezinqubo ezigcina inkunkuma ehlala phansi ikwazi ukumpontshwa futhi iyisuse ethangini, kufaka phakathi izixutshi, amapayipi okukhipha amanzi, imisele yaphansi, amaphampu enkunkuma kanye nezinhlelo zama-rake noma zama-scraper.
Izici Eziyinhloko, Izingxenye Nezinhlobo
Ukuxutsha: Ama-mixer angaphansi kwamanzi noma i-jet/recirculation yangaphandle kuvimbela inkunkuma ukuthi ingahlukani futhi yakhe uqweqwe oluqinile; usayizi uncike ezinhlayiyeni nasekuviscosity, hhayi emithethweni yamanzi.
Umsele waphansi / i-cone: I-cone noma phansi okutshekile kuqondisa inkunkuma emseleni omaphakathi ukuze ikhishwe ngamandla adonsela phansi noma ngamaphampu.
Ukukhipha ngamaphampu: Amaphampu e-progressive-cavity noma e-slurry akwazi ukuphatha izinhlayiya eziphezulu amaphampu e-centrifugal angakwazi ukuziphatha.
I-rake/scraper: Amabhuloho ahamba kancane anama-scraper ahlanganisa inkunkuma endaweni yokukhipha emathangini amakhulu.
Ukukhipha amanzi: I-decanters entantayo ikhipha amanzi angaphezulu ngaphandle kokuphazamisa inkunkuma.
Izinhlelo Zokusebenza Nezimo Zokusetshenziswa
Ukugcinwa kwe-sludge kamasipala, ukudla kwe-digestion, ukuhlanza i-sludge yezimboni, nokwamukela i-septage, lapho ukuqina okuphezulu nokulawulwa kwephunga kuhamba phambili.
Izinto Okufanele Zicatshangelwe Kwezobuchwepheshe
I-rheology ye-sludge, hhayi umthamo, iqondisa ukukhethwa kwe-mixer namaphampu. Ukuxuba kancane kuvumela uqweqwe kanye nengqimba ehlala phansi ukuthi yakheke, kulahlekelwe umthamo unomphela futhi kwenze kube nzima ukukhipha. Ikhoni noma phansi etshekile kanye ne-drain yaphansi kuyindlela elula futhi ethembekile yokukhipha; amathangi amakhulu afaka i-rake bridge. Ngenxa yokuthi amathangi e-sludge avame ukungabi nawo umoya futhi abe ne-H2S, ukukhipha nokungena kudinga izinqubo zezindawo ezivalekile: ukuhlolwa kwegesi, ukungenisa umoya, izimvume futhi, ngokufanelekile, ukukhipha ngaphandle kokungena.
I-coating yethangi kufanele ifanele kokubili i-mixed liquor kanye ne-gas headspace, njengoba ukuxuba kugcina izinto ezilimazayo zithintana ne-shell.
Izinzuzo Nezithiyo
Izinzuzo:
Ukuxuba okufanele kugcina udaka lukwazi ukumpontshwa futhi umthamo usetshenziseka; ukuklanywa okufanele kokukhipha (ikhowuni, idreyini, i-rake) kunciphisa umsebenzi kanye nengozi yokungena. Ama-decanters avikela izinga le-supernatant.
Izithiyo:
Ama-mixer nama-rake engeza izindleko kanye nezigaba ze-nozzle/umthwalo; amaphampu kufanele abe ngamazinga e-solids noma ayavaleke. Ukungena endaweni evinjelwe ukuhlanza kuyingozi futhi kufanele kuncishiswe ngokuklanywa.
Ukuqhathanisa Nomhlahlandlela Wokukhetha
Indlela | Ukusetshenziswa okungcono kakhulu | Qaphela |
I-mixer engaphansi kwamanzi | Gcina kufana | Ukulinganisa ngokusekelwe ku-rheology |
Phansi kwekhoni + umsele wokudonsa | Ukukhipha okulula | Idinga ukuthambeka kwaphansi |
Ipompo lodaka | Ukususwa kwezinto eziqinile eziphezulu | Sebenzisa uhlobo olukalwe izinto eziqinile |
Ibhuloho lokuhlakula | Amathangi amakhulu | Izindleko, isimo somthwalo |
Isihlukanisi esintantayo | Ukudonsa kwamanzi angaphezulu | Gwema ukuphazamisa udaka |
Izinqubo Ezinhle Kakhulu Nokuthi Ungakhetha Kanjani
Linganisa izihlanganisi ngokwe-rheology yodaka, hhayi imithetho yamanzi. Nikeza indawo ethambekile noma phansi kwekhoni enomsele wokudonsa phansi, futhi ucacise amapompo akalwe izinto eziqinile. Nciphisa ukungena ngama-decanters nokuxuba kwangaphandle, futhi uphoqelele ukuphepha kwendawo evinjelwe kunoma yikuphi ukungena ethangini.
Xuba udaka ngokwe-rheology yalo ngama-submersible noma ama-jet mixers, futhi uwukhiphe ngaphansi kwekhoni, umsele wokudonsa, ipompo elikalwe izinto eziqinile noma i-rake. Ngaphezu kwakho konke, klama ukuze ugweme ukungena endaweni evinjelwe, ngoba amathangi odaka ayingozi ye-H2S.
Imibuzo Evame Ukubuzwa (FAQ)
Kungani ngingakwazi ukuphatha udaka njengamanzi ekuxubeni?
I-sludge inokuqina okuphezulu kanye ne-viscosity; ukungaxutshi kahle kuyivumela ukuthi ihlukane futhi yenze uqweqwe, ilahlekelwe unomphela umthamo osebenzisekayo. Usayizi we-mixer uncike kwi-rheology, hhayi umthamo wethangi.
Iyiphi indlela elula yokukhipha ithangi le-sludge?
I-cone noma phansi okuthambekile okunomsele ophakathi ngezansi kuvumela i-sludge ukuthi yehle ngamandla adonsela phansi noma ikhishwe ngepompi ngokuhlanzekile. Phansi oyisicaba kudinga ama-rake noma ukukhipha ngesandla, okunzima ngomsebenzi futhi kuyingozi.
Iyiphi ipompi ebamba i-sludge?
Ama-progressive-cavity noma ama-slurry-type pump abamba ukuqina okuphezulu; ama-centrifugal pump ajwayelekile ayavaleka. Fanisa ipompi nokuqukethwe kwe-solids kanye ne-abrasiveness.
Kungani ukungena ethangini le-sludge kuyingozi?
Amathangi e-sludge ngokuvamile awanomoya futhi akhiqiza i-hydrogen sulphide, igesi enobuthi, engakhanyi ngephunga eliphezulu. Ukungena kudinga ukuhlolwa kwegesi, ukungenisa umoya kanye nezimvume, ngakho klama ukukhipha nokuhlanza ngaphandle kokungena lapho kungenzeka khona.
Yenzani i-floating decanter?
Idonsa i-supernatant ecacile phezulu ngaphandle kokuphazamisa i-sludge ehlezi phansi, ivikela izinga le-supernatant ngesikhathi sokukhipha.
