Sodium chlore thiab sodium hypochlorite yog ob qho oxidants, tab sis sockidize cod ntawm chav tsev kub, thiab tsis muaj kev cuam tshuam rau kev tshem tawm cov cim txhua.
01 Kom tsis muaj menyuam thiab Membrane ntxuav
Sodium hypochlorite tuaj yeem tsis muaj tshuaj tua kab thiab ntxuav tawm rau ob qho laj thawj. Ua ntej, cov khoom siv ecologen tshiab, nrog nws cov khoom muaj zog oxidizing, thiab cov kab mob, yog li tua cov kab mob pathogenic microorganisms. Nws yog ib txoj kev ntaus nrig sab nraud.
Thib ob, ntawm lub cell membrane yog qhov tsis zoo rau cov acid yog qhov nruab nrab me me molecule uas tuaj yeem nkag rau hauv cov kab mob cell, reacting nrog tua cov kab mob, uas yog kev txawj sib deev.
Yog tias muaj tshwm sim los ua qee ammonia nitrogen nyob rau hauv cov dej, nws yuav tshwm sim nrog sodium hypochlorite los ua chloramine cov khoom sib txuas, tab sis tuaj yeem ruaj khov hauv dej thiab txuas ntxiv rau kev tawm suab.
Membrane ntxuav yog hais txog backashing mbr daim ntaub nyias nyias nrog tshuaj. Cov neeg uas siv MBR thev naus laus zis yuav muab rau daim nyias nyias nyias, thiab yog tias nws muaj kev cuam tshuam ntau dua, nws yuav cuam tshuam rau cov membrane Flux.
Qhov tseem ceeb ntawm daim duab ntxhua khaub ncaws yog tseem tsis muaj menyuam, thiab sodium hypochlorite yuav ib txwm poob tawm ntawm MBR IDBRANE.
02 Tshem Tawm Cod
Sodium hypochlorite tuaj yeem siv ua Cod kev tshem tawm. Qhov no tsis yog heresy. Nws yog vim muaj cov khoom siv oxidizing muaj zog ntawm cov ecologen ecologen. Nws tuaj yeem oxidize ib feem ntawm Cod, tab sis nws tsis yog tus phooj ywg zoo rau sludge, yog li sim siv nws me li sai tau.
Cov chloride ions decomposed los ntawm sodium hypochlorite hauv dej yuav tseem cuam tshuam nrog kev txiav txim siab nrog kev cuam tshuam nrog sodium chlorate yog txawv. Kev cuam tshuam ntawm Sodium hypochlorite yog los ua cod falsely siab.
03 decolorization & tshuaj dawb
Tseem cia siab rau cov khoom ntiag tug oxidizing ntawm cov ecologen ecologen tshiab. Sodium hypochlorite feem ntau yog siv los ua decolorizer lossis cleking tus neeg sawv cev hauv kev luam ntawv thiab tawg ntho kom tawg. Qhov sib txawv ntawm ob yog: Cov tshuaj tiv thaiv nrog hlau ions los tsim ib nag los ua ib daus los ua kev txiav txim siab; oxidation ntawm organic dyes yog hu ua kev cai ua tshuaj dawb.
04 Tshem Tawm Ntawm Ammonia Nitrogen
Raws li tau hais ua ntej, sodium hypochlorite yuav tsim chloramine compounds nrog ammonia nitrogen. Tam sim no cia txoj kev ua raws li peb cov kwv tij chloramine.
Nh 3+ hocl → H2O + NH2Cl + Dichhloramine NHCL → HocCL → H2O + NCL3 trichloramine
Cov kev tawm tsam no yog cov kev tawm tsam tau thim rov qab. Peb tug kwvtij tuaj yeem hloov rov qab thaum twg los tau. Raws li rau seb lawv puas hloov lossis tsis yog, txhua yam yog nyob ntawm PH. Yog tias koj xav tau kev txwv tsis pub cuam tshuam, koj yuav tsum ua kom lub p v tsis muaj zog alkaline, txuas ntxiv ntawm H +, txhawb kev ua haujlwm, thiab xyuas kom meej tias cov tshuaj tiv thaiv yuav tsis thim rov qab.
05 cyanide rhuav tshem hauv electroplating wastewater
Cyanide ua lub luag haujlwm sib luag hauv cov txheej txheem hluav taws xob, uas tuaj yeem ua rau txheej txheej zoo thiab du. Yog li ntawd, dua li ntawm cov hlau hnyav, qhov no yog cov tshuaj muaj ntau hauv electroplating wastewater. Muaj cov txheej txheem tshwj xeeb hu ua cyanide kev puas tsuaj thaum kho hluav taws xob.
Sodium hypochlorite rhuav tshem ntawm cyanide yog hu ua chlorine oxidation txoj kev. Cyanide yog thawj oxidized rau hauv Cyanate, thiab tom qab ntawd oxidized rau hauv kev tsis muaj teeb meem nitrogen thiab carbonate. Cov txheej txheem yog qhov nyuaj.
