Ukunqunywa kwe-chlorine esele/ingqikithi ye-chlorine nge-DPD spectrophotometry
Isibulala-magciwane se-chlorine siwukubulala amagciwane okuvame ukusetshenziswa futhi sisetshenziswa kakhulu ohlelweni lokubulala amagciwane emanzini ompompi, amachibi okubhukuda, i-tableware, njll. Kodwa-ke, izibulala-magciwane ezine-chlorine zizokhiqiza imikhiqizo ehlukahlukene ngesikhathi sokukhipha amagciwane, ngakho ukuphepha kwekhwalithi yamanzi ngemva kwalokho. i-chlorination...Funda kabanzi -
Isingeniso se-DPD colorimetry
I-spectrophotometry ye-DPD iyindlela ejwayelekile yokuthola i-chlorine esele yamahhala kanye ne-chlorine eyinsalela esezingeni likazwelonke laseChina “Ikhwalithi Yamanzi Yamagama Nezindlela Zokuhlaziya” GB11898-89, ithuthukiswe ngokuhlanganyela yi-American Public Health Association, i-American Wate...Funda kabanzi -
Ubudlelwano phakathi kwe-COD ne-BOD
Ukukhuluma nge-COD ne-BOD Ngamagama ochwepheshe i-COD imele i-Chemical Oxygen Demand. I-Chemical Oxygen Demand iyinkomba ebalulekile yokungcoliswa kwekhwalithi yamanzi, esetshenziselwa ukukhombisa inani lezinto ezinciphisayo (ikakhulukazi izinto eziphilayo) emanzini. Isilinganiso se-COD sibalwa ngokusebenzisa i-str...Funda kabanzi -
Indlela yokunquma ikhwalithi yamanzi ye-COD-i-spectrophotometry yokugaya ngokushesha
Indlela yokulinganisa ikhemikhali yesidingo se-oxygen (COD), kungakhathaliseki ukuthi indlela ye-reflux, indlela esheshayo noma indlela ye-photometric, isebenzisa i-potassium dichromate njenge-oxidant, i-silver sulfate njenge-catalyst, kanye ne-mercury sulfate njenge-masking agent yama-ion e-chloride. Ngaphansi kwezimo ezine-asidi zase-su...Funda kabanzi -
Ungakwenza kanjani ukuhlola kwe-COD kunembe kakhudlwana?
Ukulawulwa kwezimo zokuhlaziya i-COD ekuhlanzeni indle 1. Isici esibalulekile—ukumela isampula Njengoba amasampula amanzi aqashwe lapho kuhanjiswa indle ekhaya engalingani kakhulu, isihluthulelo sokuthola imiphumela yokuqapha ye-COD enembile ukuthi amasampula kufanele amele. Ukuze kuzuzwe...Funda kabanzi -
Uguquko emanzini angaphezulu
Iyini imfucumfucu? I-turbidity isho izinga lokuvinjwa kwesisombululo ekudluleni kokukhanya, okuhlanganisa ukuhlakazeka kokukhanya ngento emisiwe kanye nokumuncwa kokukhanya ngama-molecule asolute. I-Turbidity ipharamitha echaza inani lezinhlayiya ezimisiwe ku-li...Funda kabanzi -
Iyini i-chlorine eyinsalela emanzini nokuthi ingayithola kanjani?
Umqondo we-chlorine eyinsalela I-chlorine eyinsalela inani le-chlorine etholakalayo esele emanzini ngemva kokuba amanzi ehlanjululwe futhi ebulawa amagciwane. Le ngxenye ye-chlorine yengezwa ngesikhathi sokwelashwa kwamanzi ukuze kubulawe amagciwane, ama-microorganisms, izinto eziphilayo kanye ne-inorganic matt ...Funda kabanzi -
Isifinyezo sezindlela zokuhlaziya izinkomba eziyishumi nantathu eziyisisekelo zokwelashwa kwendle
Ukuhlaziya ezimbonini zokuhlanza indle kuyindlela yokusebenza ebaluleke kakhulu. Imiphumela yokuhlaziya iyisisekelo sokulawulwa kwendle. Ngakho-ke, ukunemba kokuhlaziywa kufuna kakhulu. Ukunemba kwamanani okuhlaziya kufanele kuqinisekiswe ukuze kuqinisekiswe ukuthi ukusebenza okuvamile kohlelo ...Funda kabanzi -
Isingeniso se-BOD5 sokuhlaziya kanye nezingozi ze-BOD ephezulu
Imitha ye-BOD iyithuluzi elisetshenziswa ukuthola ukungcola kwemvelo emanzini. Amamitha we-BOD asebenzisa inani lomoya-mpilo osetshenziswa izinto eziphilayo ukuze ahlukanise izinto eziphilayo ukuze ahlole ikhwalithi yamanzi. Umgomo wemitha ye-BOD usekelwe enqubweni yokubola ukungcola kwe-organic emanzini nge-bac...Funda kabanzi -
Uhlolojikelele lwama-ejenti okuhlanza amanzi ahlukahlukene asetshenziswa kakhulu
Inkinga yamanzi yaseYancheng kulandela ukuqubuka kwe-algae eluhlaza okwesibhakabhaka e-Taihu Lake isiphinde yahlaba umkhosi ngokuvikelwa kwemvelo. Njengamanje, imbangela yokungcola isihlonziwe ekuqaleni. Izitshalo zamakhemikhali ezincane zihlakazekile emithonjeni yamanzi lapho izakhamizi ezingama-300,000 ...Funda kabanzi -
Uphakeme kangakanani usawoti ongaphathwa ngamakhemikhali ezinto eziphilayo?
Kungani amanzi angcolile anosawoti omningi kunzima kangaka ukuwaphatha? Kufanele siqale siqonde ukuthi ayini amanzi angcolile anosawoti omningi kanye nomthelela wamanzi angcolile anosawoti omningi ohlelweni lwe-biochemical! Lesi sihloko sidingida kuphela ukwelashwa kwamakhemikhali e-biochemical emanzini angcolile anosawoti omningi! 1. Ayini amanzi angcolile anosawoti omningi? Imfucuza enosawoti omningi...Funda kabanzi -
Isingeniso sobuchwepheshe bokuhlola ikhwalithi yamanzi obusetshenziswa kakhulu
Okulandelayo yisingeniso sezindlela zokuhlola: 1.
