Sodium bicarbonate (nhcox), feem ntau yog hu ua ci dej qab zib, yog ib tug me alkaline ntsev nrog ne {{{{{corrosive Pa. Nws tau pom tau zoo tshaj plaws hauv ntau cov kev kho dej khib nyiab. Tshaj li PHOM KEV TXHEEJ TXHEEM, nws cov ntawv thov suav nrog cov khoom siv nag lossis daus, kev pab tsis muaj ntxhiab, thiab kev pab cuam sib xyaws, muab cov tswv yim ua haujlwm siab.
1. Hlau ua thiab Electroplating Kev Lag Luam
Hnyav Hlau Ion Precipitant
NAHCO₃ tau siv los kho cov dej khib nyiab uas muaj cu²⁺, pb²⁺, zn²⁺, ni²⁺, thiab lwm cov hlau hnyav. Nws maj mam tso tawm cov pa roj carbonate thiab hydroxide ions, tsim kev tswj hwm daus daus lossis hydroxides, txo txoj kev pheej hmoo ntawm rov ua dua.
Kev hloov kho electrolytic cell effluent
Acidic Wastewater los ntawm electroplating lossis anodizing tuaj yeem ua ntej {}} ne} ne, kev poob siab, txo cov khoom siv hluav taws xob ua haujlwm.
2. Tshuaj lom neeg thiab kev lag luam zoo tshuaj lom neeg
Xws li cov dej khib nyiab feem ntau muaj cov muaj zog acids (piv txwv li, hatso₄, hnoo₃) thiab lom organic. Nahaco₃ muab kev tsis muaj kev pheej hmoo, txo qhov kev pheej hmoo ntawm kev sib cais vim yog kev nyab xeeb thiab nyab xeeb dua thiab yooj yim dua rau kev tswj hwm.
Nruab nrab ntawm oxidizing wastewater
Hauv oxidizing dej khib nyiab cuam tshuam nrog h₂o₂ lossis nahaco, piv txwv li cov tshuaj siab sab nraud (piv txwv li, cov tshuaj chlorine hluav taws xob) los ntawm cov kab ke siab pH thiab kho cov kab ke ua kom muaj ntau yam.
3. Kev lag luam kev lag luam
Pho ua kom nruj ntawm cov tshuaj tua kab mob / cov tshuaj hormone
Kws lim dej ntau zaus muaj cov kua qaub tsis muaj zog. Nahant Enabes kawm tiav qib ph tuaj, txhim kho kev ua tau zoo ntawm kev kawm qib siab ua haujlwm zoo li Fenton thiab kev kho mob Ozone.
Alkalinity Txhawb rau Bioreactors
NAHO₃ pab ua kom muaj ntev ntawm 6.5 thiab 8.5 hauv kev kho zaub mov zoo {2} Kev nplua nuj lom neeg thiab txhim kho ammonia nitrogen thiab cod tshem tawm.
4. Khib Txiag Khib Nyiab thiab FLUE Gas Scrubbing
Nruab nrab ntawm qhuav desulfurization quav dej
NAHCO₃ NEHCO₃ NEUTALLY SCRUBBER EFFLUATIONE muaj cov lus seem (piv txwv li, ntawm tshuaj tsuagDurulfurization), tswj tau so₂ -} muaj cov kev qias tuaj thiab tsim kho kom yooj yim.
Kev kho mob ntawm ya tshauv Leachate
Hauv stabilizing ya tshauv, Nahco₃ Aids Multi-} theem pripting, txhawb nqa ya kom cov khoom ya ua ke.
5. Hlau thiab Hlau Thiab Hlau Thiab Hlau Smelting Kev Lag Luam
Kev hloov kho ntawm acidic flue roj txhuam tswv yim effluent
Nahaco ITrodes nitrous / sulfurous acids thiab lawv cov ntsev ua kua qaub, cov kua txiv qaub ua ke los ntawm Sox / Nox Scrubbing, kom nruj kev ruaj khov.
Pretricatment ntawm Acidic Leachate
Hauv Hydrometallurgurgurgurgurgurgurgurgurgurgurgurgurgurgurgurgurgurgurgy, xws li tooj liab leaching lossis tsis tshua muaj ntiaj teb extraction, Nahco₃ nce mus rau kev kho kom yooj yim rau kev kho kom yooj yim.
6. Textile Dyeing thiab papermaking kev lag luam
Ph stabilizer rau kev hloov pauv
Nahaco utralizes muaj zog acids / alkalis in textile quav dej, tswj kev ua kom pom tseeb ph rau kev tshem tawm cov zas.
Decolorization pab rau cov xim dej tsis muaj dej
Nahaces txhawb kev ua tau kev ua haujlwm ntawm cov coagulants zoo li PAC / PAF, ua kom zoo nkauj sedimentation ntawm zas dej thiab txo cov xim xim.
7. Cov tawv nqaij tawv thiab cov khoom lag luam adhesives
Chromium nag lossis daus hauv tanning effluent
NAHCO₃ MINTALILES NÃ -}} nws muaj tanning khib nyiab los ua cr (huag) ₃, yooj yim chromium rov qab.
ODOR tswj thiab kev cai ntas yeej
Nahaco reacts nrog cov roj tsw zoo li h₂s thiab ammonia los ua ntawv tsis {{volatile salts thaum dffering pH, curbing ntxiv tso.
