Ulwazi oluhlobene nokuhlolwa kwamanzi angcolile kokuphrinta kwendwangu kanye nokudaya amanzi angcolile
Amanzi angcolile endwangu ikakhulukazi amanzi angcolile aqukethe ukungcola kwemvelo, amafutha, isitashi nezinye izinto eziphilayo ezikhiqizwa ngesikhathi sokupheka kwempahla eluhlaza, ukuwasha, ukugcoba, ukusika, njll. Ukuphrinta nokudaywa kwamanzi angcolile akhiqizwa ngezinqubo eziningi ezinjengokugeza, ukudaya, ukuphrinta. ..Funda kabanzi -
Ukuhlolwa kwamanzi angcolile ezimbonini kanye nekhwalithi yamanzi
Amanzi angcolile ezimbonini ahlanganisa amanzi angcolile akhiqizwayo, indle yokukhiqiza kanye namanzi okupholisa. Kubhekiselwa emanzini angcolile kanye noketshezi olulahlwayo olukhiqizwe ohlelweni lokukhiqizwa kwezimboni, oluqukethe izinto zokukhiqiza ezimbonini, imikhiqizo ephakathi nendawo, imikhiqizo ephumayo kanye nokungcola okukhiqizwe embonini...Funda kabanzi -
Ungazikhetha kanjani izitsha eziqinile, eziwuketshezi, nezisetshenziswayo zokuhlola amanzi angcolile? Iseluleko sethu sithi…
Izinkomba zekhwalithi yamanzi zokuhlola azihlukaniseki ekusetshenzisweni kwezinto ezisetshenziswayo ezihlukahlukene. Amafomu ajwayelekile asebenzisekayo angahlukaniswa abe izinhlobo ezintathu: okusebenzisekayo okuqinile, okusebenzisekayo okuwuketshezi, kanye nezinto ezisebenzisekayo zamabhodlela e-reagent. Sikwenza kanjani ukukhetha okungcono kakhulu lapho sibhekene nezidingo ezithile? Okulandelayo ...Funda kabanzi -
I-Eutrophication of water bodies: the green crisis of the water world
I-Eutrophication yemizimba yamanzi ibhekisela esenzakalweni sokuthi ngaphansi kwethonya lemisebenzi yabantu, izakhi ezifana ne-nitrogen ne-phosphorus ezidingwa izinto eziphilayo zingena emanzini ageleza kancane njengamachibi, imifula, amatheku, njll. ngobuningi, okuholela ekukhiqizeni ngokushesha ulwelwe ne...Funda kabanzi -
I-Chemical oxygen demand (COD): irula elingabonakali lekhwalithi yamanzi enempilo
Endaweni esihlala kuyo, ukuphepha kwekhwalithi yamanzi kuyisixhumanisi esibalulekile. Nokho, izinga lamanzi alibonakali ngaso sonke isikhathi, futhi lifihla izimfihlo eziningi esingakwazi ukuzibona ngokuqondile ngamehlo ethu enqunu. Isidingo somoya-mpilo wamakhemikhali (COD), njengepharamitha ebalulekile ekuhlaziyeni izinga lamanzi, kufana nomthetho ongabonakali...Funda kabanzi -
Ukunqunywa kwe-turbidity emanzini
Izinga lamanzi: Ukunqunywa kwe-turbidity (GB 13200-1991)” isho indinganiso yamazwe ngamazwe ISO 7027-1984 “Izinga lamanzi – Ukunqunywa kwe-turbidity”. Leli zinga licacisa izindlela ezimbili zokunquma i-turbidity emanzini. Ingxenye yokuqala i-spectrophotometry, okuyi...Funda kabanzi -
Izindlela zokutholwa ngokushesha kwezinto eziqinile ezimisiwe
Izinto eziqinile ezimisiwe, njengoba negama lisho, ziyizinhlayiyana ezintanta ngokukhululekile emanzini, ngokuvamile phakathi kwama-microns angu-0.1 nama-microns angu-100 ngosayizi. Zihlanganisa kodwa azikhawulelwe ku-silt, ubumba, ulwelwe, ama-microorganisms, i-molecular organic matter, njll., ukwakha isithombe esiyinkimbinkimbi se-m...Funda kabanzi -
Yiziphi izinkinga ithuluzi le-COD elizixazululayo?
Ithuluzi le-COD lixazulula inkinga yokulinganisa ngokushesha nangokunembile isidingo sekhemikhali komoyampilo emizimbeni yamanzi, ukuze kunqunywe izinga lokunukubezeka kwemvelo emizimbeni yamanzi. I-COD (isidingo somoya-mpilo wamakhemikhali) iyinkomba ebalulekile yokulinganisa izinga lokunukubezeka kwemvelo emanzini...Funda kabanzi -
Ukusetshenziswa kwe-ORP ekuhlanzeni indle
Imele ini i-ORP ekuhlanzeni indle? I-ORP imele amandla e-redox ekuhlanzeni indle. I-ORP isetshenziselwa ukukhombisa izakhiwo ze-macro redox zazo zonke izinto kwisisombululo esinamanzi. Ukuphakama kwamandla e-redox, kuqina indawo ye-oxidizing, kanye namandla e-redox aphansi, i-str...Funda kabanzi -
Nitrogen, Nitrate Nitrogen, Nitrite Nitrogen kanye Kjeldahl Nitrogen
I-nitrogen iyisici esibalulekile esingaba khona ngezindlela ezahlukene emanzini nasenhlabathini ngemvelo. Namuhla sizokhuluma ngemiqondo ye-nitrogen ephelele, i-ammonia nitrogen, i-nitrate nitrogen, i-nitrite nitrogen ne-Kjeldahl nitrogen. Ingqikithi ye-nitrogen (TN) iyinkomba evame ukusetshenziswa ukukala inani...Funda kabanzi -
Ukuthuthukiswa kokutholwa kwe-BOD
Isidingo se-biochemical oxygen (BOD) singenye yezinkomba ezibalulekile zokulinganisa ikhono lezinto eziphilayo emanzini ukuthi zonakaliswe ngamakhemikhali amancane, futhi iyinkomba eyinhloko yokuhlola umthamo wokuzihlanza kwamanzi kanye nezimo zemvelo. Ngokusheshisa ...Funda kabanzi -
Ukuthuthukiswa kokutholwa kwesidingo sekhemikhali komoyampilo (COD).
Isidingo somoya-mpilo wamakhemikhali sibuye sibizwe ngesidingo somoya-mpilo wamakhemikhali (isidingo se-oksijini samakhemikhali), esibizwa nge-COD. Kuwukusetshenziswa kwama-chemical oxidants (afana ne-potassium permanganate) ukuze kufakwe i-oxidize futhi kubolise izinto ezi-oxidizable emanzini (njengezinto eziphilayo, i-nitrite, i-ferrous salt, i-sulfide, njll.), i...Funda kabanzi
