Isihlungi se-carbon esicushiwe ngokuvamile sisetshenziswa ngokuhambisana nesihlungi sesihlabathi se-quartz.Awukho umehluko obalulekile phakathi komzimba wethangi nesihlungi sesihlabathi se-quartz.Idivayisi yokusabalalisa amanzi yangaphakathi kanye nepayipi elikhulu lomzimba kufanele lihlangabezane nezidingo zokusetshenziswa.
Isihlungi sekhabhoni esicushiwe sinemisebenzi emibili:
(1) Sebenzisa indawo esebenzayo yekhabhoni ecushiwe ukuze ususe i-chlorine yamahhala emanzini, ukuze ugweme ukugcotshwa kwenhlaka ye-ion exchange, ikakhulukazi inhlaka yokushintshisana nge-cation ohlelweni lokuhlanza amanzi ngamakhemikhali, nge-chlorine yamahhala.
(2) Khipha izinto eziphilayo emanzini, njenge-humic acid, njll., ukuze unciphise ukungcoliswa kwenhlaka eqinile ye-anion exchange nge-organic matter.Ngokwezibalo, ngokusebenzisa isihlungi se-carbon esicushiwe, ama-60% kuya ku-80% wezinto ze-colloidal, cishe u-50% wensimbi kanye no-50% kuya ku-60% wezinto eziphilayo zingasuswa emanzini.
Ekusebenzeni kwangempela kwesihlungi se-carbon esicushiwe, ukuthuthumela kwamanzi angena embhedeni, umjikelezo wokuwasha ngemuva, namandla okugeza i-backwash kubhekwa ngokuyinhloko.
(1) Ukuguquguquka kwamanzi angena embhedeni:
I-turbidity ephezulu yamanzi angena embhedeni izoletha ukungcola okuningi kakhulu kungqimba lwesihlungi se-carbon esicushiwe.Lokhu kungcola kubambeke kungqimba lwesihlungi sekhabhoni esicushiwe, futhi kuvimbe igebe lesihlungi kanye nengaphezulu lekhabhoni ecushiwe, kuvimbela umphumela wayo wokukhanga.Ngemuva kokusebenza isikhathi eside, obuyisela emuva uzohlala phakathi kwezingqimba zokuhlunga i-carbon ecushiwe, enze ifilimu yodaka engakwazi ukukhukhuleka, okubangela ukuba ikhabhoni ecushiwe iguge futhi ihluleke.Ngakho-ke, kungcono kakhulu ukulawula i-turbidity yamanzi angena kusihlungi se-carbon esicushiwe ngaphansi kwe-5ntu ukuqinisekisa ukusebenza kwawo okuvamile.
(2) Umjikelezo wokuwashwa ngemuva:
Ubude bomjikelezo we-backwash yisici esiyinhloko esihlobene nekhwalithi yesihlungi.Uma umjikelezo we-backwash mfushane kakhulu, amanzi okugeza ngemuva azomosha;uma umjikelezo we-backwash umude kakhulu, umphumela we-adsorption wekhabhoni ecushiwe uzothinteka.Ngokuvamile, lapho amanzi angena embhedeni engaphansi kuka-5ntu, kufanele agezwe ngemuva kanye njalo ezinsukwini ezi-4-5.
(3) Ukuqina kwe-backwash:
Ngesikhathi sokuwashwa emuva kwesihlungi sekhabhoni esicushiwe, izinga lokunwetshwa kongqimba lokuhlunga linethonya elikhulu ekutheni ungqimba lokuhlunga lugezwe ngokuphelele yini.Uma izinga lokunweba lesendlalelo sokuhlunga lincane kakhulu, ikhabhoni ecushiwe esendlaleni esingezansi ayikwazi ukumiswa, futhi indawo yayo ayikwazi ukugezwa kahle.Ngokusebenza, izinga lokunwetshwa kwesilawuli elijwayelekile lingu-40%~50%.(4) Isikhathi sokuwashwa ngemuva:
Ngokuvamile, lapho izinga lokunwetshwa lesendlalelo sesihlungi singu-40%~50% futhi amandla okugoqa angu-13~15l/(㎡·s), isikhathi sokugeza ngemuva kwesihlungi sekhabhoni esicushiwe ngu-8~10min.
