Isincomo Sensimbi Yekhwalithi Yamanzi Yase-China: Uchungechunge lwezomnotho kanye nekhwalithi ephezulu ye-Qinglan LH-P3 umhloli osheshayo wepharamitha eyodwa
Emikhakheni eminingi efana nokuqapha imvelo, ukwenza imithi, ukuphisa, ukwenza amaphepha okudla, amakhemikhali ephethiloli, njll., ukunqunywa kwepharamitha okusheshayo nokunembile kubalulekile. Umhloli wekhwalithi yamanzi we-Lianhua Technology osanda kwethulwa we-Qinglan LH-P3 unepharamitha eyodwa ephathekayo akagcini nje ngokusebenza...Funda kabanzi -
Isincomo Sensimbi Yekhwalithi Yamanzi Yase-China | I-LH-A109 Multi-parameter Digestion Instrument
Ezivivinyweni zokuhlola izinga lamanzi, ithuluzi lokugaya liyithuluzi elibalulekile nelibalulekile. Namuhla, ngithanda ukuncoma ithuluzi lokugaya elingenamali, elisebenziseka kalula kuwo wonke umuntu-LH-A109 ithuluzi lokugaya elinamapharamitha amaningi. 1. Inomnotho futhi iyathengeka, inani elikhulu lemali E...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 -
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.

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
