Ngesikhathi sokukhiqiza amabhizinisi e-petrochemical,
Ivolumu yokukhipha amanzi angcolile inkulu futhi ukwakheka kuyinkimbinkimbi.
Inqubo yokuhlanganisa inzima ukubhekana nayo!
Ikakhulukazi utshwala obunosawoti omningi kanye ne-COD ephezulu ekugcineni,
Uma ingeke yomiswe kahle,
Kuzothinta kakhulu ukugcwaliseka "kokukhishwa kwe-zero" kwamanzi angcolile!
Inqubo evamile yokomiswa kukamama kotshwala ekupheleni kwenqubo yokwelashwa kwamanzi angcolile e-petrochemical
Enqubweni yokukhiqiza yamabhizinisi e-petrochemical, inqubo yokuhwamuka/iqhwa iyingxenye yenqubo evame ukusetshenziswa ukuthola umkhiqizo wokugcina.Inqubo ye-crystallization izoholela ekuthuthukisweni kokungcola okubonakalayo, ngakho-ke kuzokhiqizwa utshwala obuncane noma obuncane obuhwamukile ohlelweni lokukhiqiza.
Njengamanje, ukwelashwa kwalezi zinhlobo zotshwala bomama abahwamukayo ngokuyisisekelo kuxazululwa njengenkinga ethile enqubweni yokukhiqiza.Ngenxa yezakhiwo ezahlukene zotshwala kamama uqobo, izindlela zokwelashwa nazo zihlukile.Ukulahlwa kotshwala kamama obuhwamukile obunosawoti omningi kanye ne-COD ephezulu, ubuchwepheshe bokwelapha obujwayelekile emakethe ikakhulukazi ukomiswa kwe-drum scraper, ukomiswa kwe-rake, iketela elilodwa lesitimu kanye nenqubo yokufaka ikristalu yokuhwamuka kwezinga lokushisa eliphansi.Izici zezinqubo ezine ezinkulu mayelana nomthamo wokucubungula, ukusetshenziswa kwesitimu, ukusetshenziswa kwamandla, izici zepharamitha yokusebenza, izici zemishini kanye nobubanzi bokusebenza kuqhathaniswa kanje:

△Ukuhlaziywa okuqhathanisayo kwemishini evamile yokomisa kanye nenqubo ye-crystallization yezinga lokushisa eliphansi
I-Weishengda yokuvikelwa kwemvelo ye-crystallizer yokuhwamuka kwezinga lokushisa ephansi isetshenziselwa ngokukhethekile ukunciphisa kanye nokugxila kwamanzi angcolile aphezulu.I-scraper eyakhelwe ngaphakathi iphumelela kakhulu ekwelapheni uketshezi olugxilile olulula ukunamathela odongeni.Kunconywa ikakhulukazi ekwelapheni uketshezi oluhlangene noma olucwebezelayo, olufana namanzi angcolile ensimbi esindayo, amanzi anosawoti amaningi, utshwala bomama, amanzi agxilisiwe e-osmosis, njll. Uhlelo lusebenzisa ijakhethi yepuleti le-Miller lokushintshanisa ukushisa, idigri yevacuum egumbini lokuhwamuka -95~-97kPa, futhi izinga lokushisa lokuhwamuka ngokuvamile liyagcinwa liphakathi kuka-40~45°C.Igumbi lokuhwamuka lisebenzisa i-spiral scraper ukuze inyakaze, engaqinisekisa ukushisa okufanayo.Ngesikhathi esifanayo, ukubeka i-shaft enyakazayo ekushiseni kungathuthukisa umphumela wokushintshanisa ukushisa futhi kuthuthukise ukoma kokuphumayo.
Uhlelo lulawula ngokuzenzakalelayo ngokugcwele, olunezici zokukhishwa okuzenzakalelayo, ukuhlanza okuzenzakalelayo, ukuphathwa kwepulatifomu yefu yemishini nokunye.Umphumela wokuphuma kwamanzi muhle, akukho ukungcoliswa kwegesi engcolile, ukungcoliswa kokushisa nezinye izenzakalo, futhi lonke uhlelo lusebenza ngendlela evaliwe.

2 Ukusetshenziswa okujwayelekile kwenqubo ye-WSD yokuhwamuka kwe-crystallization yezinga lokushisa eliphansi emanzini angcolile e-petrochemical
Iklayenti yibhizinisi elikhiqiza uwoyela negesi elikhiqiza igesi yemvelo.Inani elikhulu lamanzi angcolile angathathi hlangothi, amanzi abuyiselwe ajwayelekile, ukungcola kwamanzi ajikelezayo kanye nokungcola okubhoyili kuyakhiqizwa.Kunenkinga yamanzi angcolile anosawoti omningi, anomthelela omkhulu emshinini wokuhlanza indle.Amanzi angcolile anosawoti omningi aqukethe i-sodium sulfate kanye nenani eliphakeme le-COD.Ngemuva kwesistimu yokomisa utshwala efakwe ku-WSD (amanzi angcolile okuhlanza nsuku zonke angu-10m³), amanzi akhiqiziwe awanawo umbala futhi akanalo iphunga elimnandi, futhi inani le-pH liphakathi kuka-6 no-9. Uma ukugcwala kwe-sulfite + sulfate kungaphansi kuka-10mg/ L, kanye ne-COD ingaphansi kuka-40mg/L, amanzi akhiqiziwe afanelekile, ahlangabezana nezidingo zokungena echibini lamakhemikhali ezinto eziphilayo ukuze alashwe futhi ahlangabezane nezidingo zokungcola.

Ukwelashwa kokukhipha i-Zero kwamanzi angcolile e-petrochemical kuyisiqondiso sokuthuthukiswa kwesikhathi esizayo.Ukwehliswa okukhulu kwamanzi angcolile e-petrochemical ngobuchwepheshe bokuhwamuka kwezinga lokushisa eliphansi kunganciphisa ngempumelelo umthwalo wokucutshungulwa kokuhwamuka kanye nekristalu, kunciphise izindleko eziphelele zobunjiniyela bokwelapha obukhipha i-zero-discharge, futhi kunikeze ireferensi nereferensi yokusetshenziswa nokuthuthukiswa kobuchwepheshe bokukhipha i-zero-discharge imboni ye-petrochemical esikhathini esizayo.
