Uhlelo Lokuvuna Amanzi Emvula Ukuhlanza Amanzi Elanga
Incazelo yomkhiqizo
Ukuqoqwa kwamanzi emvula kuthonywa izinkathi zonyaka, ngakho-ke kuyalulekwa ukusebenzisa izindlela zokwelashwa ngokomzimba, zamakhemikhali, nezinye ukuze zivumelane nokusebenza okungaqhubeki kwezinkathi zonyaka.Ukuhlukaniswa kwemvula nokungcola kubandakanya ukuqondisa amanzi emvula ethangini lokugcina, bese kwenziwa ukwelashwa ngokomzimba namakhemikhali endaweni eyodwa.Izindlela eziningi zobuchwepheshe ezikhona zokuhlinzeka ngamanzi kanye nokuhlanza amanzi angcolile zingasetshenziswa ukulungisa amanzi emvula.Ngokuvamile, amanzi emvula anekhwalithi enhle akhethwa ukuze aqoqwe futhi agaywe kabusha.Inqubo yokwelapha kufanele ibe lula, isebenzisa inhlanganisela yokuhlunga kanye ne-sedimentation.
Uma kunesidingo esiphezulu sekhwalithi yamanzi, izinyathelo zokwelashwa ezithuthukisiwe ezihambisanayo kufanele zengezwe.Lesi simo sisebenza kakhulu ezindaweni lapho abasebenzisi benezidingo zekhwalithi yamanzi ephakeme, njengasekugcwalisweni kwamanzi okupholisa amasistimu okupholisa umoya nokunye ukusetshenziswa kwamanzi ezimbonini.Inqubo yokuhlanza amanzi kufanele isekelwe ezidingweni zekhwalithi yamanzi, okuhlanganisa ukwelapha okuthuthukisiwe okufana nokuhlanganisa, ukubola, nokuhlunga okulandelwa yikhabhoni ecushiwe noma amayunithi okuhlunga ulwelwesi.
Ngesikhathi sokuqoqwa kwamanzi emvula, ikakhulukazi lapho ukugeleza kwamanzi kuqukethe inzika eyengeziwe, ukuhlukanisa inhlabathi kunganciphisa isidingo sokugezwa kwethangi lokugcina.Ukuhlukaniswa kwenhlabathi kungafinyelelwa kusetshenziswa okokusebenza okungaphandle kweshalofu noma ngokwakha amathangi okuhlalisa afana namathangi okuhlalisa ayisisekelo.
Lapho amanzi angcolile aphuma kule nqubo engahlangabezani nezidingo zekhwalithi zamanzi ze-landscape yamanzi yamanzi, kungase kwenzeke ukucabangela ukusebenzisa ikhono lemvelo lokuhlanzeka lomzimba wamanzi okwakheka kwezwe kanye nezindawo zokunakekelwa kwekhwalithi yamanzi kanye nokuhlanza ukuze kuhlanzeke amanzi emvula axubile emanzini. umzimba.Lapho indawo yamanzi enezimfuneko ezithile zekhwalithi yamanzi, izindawo zokuhlanza ngokuvamile ziyadingeka.Uma ukugeleza kwamanzi kusetshenziselwa ukungena emanzini, amanzi emvula angaqondiswa ngotshani noma emiseleni yamatshe osebeni lomfula ukuze avumele ukuhlanzwa kokuqala ngaphambi kokungena emanzini, ngaleyo ndlela kuqedwe isidingo sezindawo zokuqala zokukhipha amanzi emvula.Izindikimba zamanzi zezwe ziyizindawo zokugcina amanzi emvula ezibizayo.Uma izimo zivumela umthamo wokugcina amanzi emvula emanzini, amanzi emvula kufanele agcinwe endaweni yamanzi endaweni esikhundleni sokwakha amathangi okugcina amanzi emvula ahlukene.
Ukwelashwa kwe-sedimentation kungafinyelelwa kusetshenziswa imigodi ye-sedimentation kanye nama-reservoirs ukuthungwa kwemvelo ngesikhathi sokugcinwa kwamanzi emvula.Uma usebenzisa ukuhlunga okusheshayo, usayizi wembotshana wesihlungi kufanele ube phakathi kwama-micrometer ayi-100 kuye kwangama-500.Izinga lamanzi lalolu hlobo lokusebenzisa liphakeme kunalelo lokunisela endaweni eluhlaza, ngakho-ke ukucwenga kwe-coagulation noma ukuntanta kuyadingeka.Ukuhlungwa kwesihlabathi kuyanconywa ukuze kuhlungwe ukujiya, okunosayizi wezinhlayiyana ezingu-d kanye nogqinsi lombhede wokuhlunga ongu-H=800mm kuya ku-1000mm.I-Polymeric aluminium chloride ikhethwa njenge-coagulant, ene-dosing concentration engu-10mg/L.Ukuhlunga kwenziwa ngesilinganiso esingu-350m3/h.Kungenjalo, ama-cartridges e-fiber ball filter angakhethwa, ngendlela ehlangene yamanzi kanye ne-airwash backwash.
Uma kunezidingo eziphakeme zekhwalithi yamanzi, kufanele kwengezwe izindlela zokwelashwa ezithuthukisiwe, ezisebenza kakhulu ezindaweni ezinezidingo zekhwalithi yamanzi ephakeme, njengamanzi okupholisa umoya, amanzi asekhaya, namanye amanzi ezimboni.Izinga lamanzi kufanele lihlangabezane namazinga afanele kazwelonke.Inqubo yokuhlanza amanzi kufanele ihlanganise ukwelashwa okuthuthukisiwe okusekelwe ezidingweni zekhwalithi yamanzi, njengokuhlangana kwe-coagulation, i-sedimentation, i-filtration, kanye nokwelashwa ngemva kokwelashwa nge-activated carbon filtration noma i-membrane filtration.
Izinsalela ezikhiqizwa ngesikhathi sokuhlanza amanzi emvula ngokuvamile aziphili, futhi ukwelashwa okulula kwanele.Lapho ukwakheka kwe-sediment kuyinkimbinkimbi, ukwelashwa kufanele kwenziwe ngokuvumelana nezindinganiso ezifanele.
Amanzi emvula ahlala echibini isikhathi eside uma kuqhathaniswa, ngokuvamile phakathi kwezinsuku ezi-1 kuya kwezingu-3, futhi anomphumela omuhle wokususa inzika.Idizayini ye-reservoir kufanele isebenzise ngokugcwele umsebenzi wayo wokudiliza.Iphampu yamanzi emvula kufanele idonse uketshezi olucacile ethangini lamanzi ngangokunokwenzeka.
Imishini yokuhlunga esheshayo ehlanganiswe nesihlabathi se-quartz, i-anthracite, amaminerali esindayo, nezinye izinto zokuhlunga ayimpahla yokwelapha eseyivuthiwe nobuchwepheshe ekwakheni ukuhlanzeka kokuphakelwa kwamanzi futhi ingasetshenziswa njengereferensi ekuhlanzeni amanzi emvula.Lapho kwamukelwa izinto ezintsha zokuhlunga nezinqubo zokuhlunga, imingcele yedizayini kufanele inqunywe ngokusekelwe kudatha yokuhlola.Ngemva kokuna kwemvula, uma usebenzisa amanzi njengamanzi okupholisa agaywe kabusha, ukwelashwa okuthuthukisiwe kufanele kwenziwe.Imishini yokwelapha ethuthukisiwe ingasebenzisa izinqubo ezifana nokuhlunga ulwelwesi kanye ne-osmosis ehlehlayo.
Ngokusekelwe kokuhlangenwe nakho, kunconywa ukuthi kusetshenziswe izindlela zokuhlunga amanzi emvula kabusha, futhi umthamo we-chlorine wamanzi okusebenzisa kabusha amanzi emvula ungabhekisela esikalini se-chlorine senkampani yokuphakela amanzi.Ngokolwazi lokusebenza oluvela phesheya, umthamo we-chlorine ulinganiselwa ku-2 mg/L kuya ku-4 mg/L, futhi ukungcola kungahlangabezana nezimfuneko zekhwalithi yamanzi kumanzi ahlukahlukene asemadolobheni.Lapho unisela izindawo eziluhlaza kanye nemigwaqo ebusuku, ukuhlunga kungase kungadingeki.
