Yuav ua li cas lub tank biochemical kho cyanide muaj cov dej khib nyiab?

Cyanide muaj cov dej khib nyiab los ntawm cov chaw haujlwm xws li electroplating, roj, coking, metallurgy, hlau ua, tshuaj fiber ntau, yas, tshuaj tua kab, thiab tshuaj lom neeg kev lag luam. Cyanide muaj cov dej khib nyiab yog cov dej khib nyiab uas muaj tshuaj lom heev, uas tsis ruaj khov hauv dej thiab yooj yim rau decompose. Inorganic thiab organic cyanide yog cov tshuaj lom heev, thiab tuaj yeem ua rau mob hnyav yog tias tib neeg noj. Cov koob tshuaj tuag ntawm cyanide rau tib neeg yog {{0}}.18, thiab potassium cyanide yog 0.12g. Qhov loj ntawm cyanide rau ntses hauv dej yog 0.04-0.1mg/L. Cov kev ntsuas tseem ceeb rau kev kho cyanide uas muaj cov dej khib nyiab suav nrog: (1) hloov kho cov txheej txheem los txo lossis tshem tawm cov pa tawm ntawm cyanide uas muaj cov dej khib nyiab, xws li siv cyanide dawb electroplating los tshem tawm cov dej khib nyiab los ntawm cov chaw ua haujlwm electroplating. (2) Cov dej khib nyiab uas muaj cov ntsiab lus cyanide siab yuav tsum tau siv dua, thiab cov dej khib nyiab uas muaj cov ntsiab lus cyanide tsawg yuav tsum tau ua kom huv si ua ntej tso tawm. Cov txheej txheem rov qab muaj xws li acidification aeration alkali cawv absorption method, steam desorption method, etc. Cov kev kho mob muaj xws li alkaline chlorination method, electrolytic oxidation method, pressurized hydrolysis method, biochemical method, biological iron method, ferrous sulfate method, air stripping method, thiab lwm yam. Txoj kev alkaline chlorination yog dav siv thiab txoj kev ferrous sulfate tsis tau kho kom zoo

Qee tus neeg hais tias nws tseem yog biotechnology. Anaerobic thev naus laus zis, uas yog ib qho ntawm cov thev naus laus zis tseem ceeb, muaj keeb kwm ntev dua li cov txheej txheem sludge. Txawm hais tias nws tau ua tsis tiav qhov ci ntsa iab hauv thaj chaw tseem ceeb ntawm kev kho cov dej phwj hauv nroog, nws tsis tau tso tib neeg pom.

Yuav ua li cas cov ntsiab lus tseem ceeb thiab kev coj cwj pwm ntawm kev kho cov dej khib nyiab yuav tsum tau muab tso rau? Koj puas xav rov ua dua lossis tsuas yog tshem tawm? Muaj peev xwm lossis kev siv hluav taws xob? Consumption los yog sustainability?

Nws yog nws uas hloov lub tsom xam ntawm kev kho dej khib nyiab rau hauv dab tsi tuaj yeem tau txais los ntawm cov dej khib nyiab, tsis yog tsuas yog tshem tawm dab tsi; Nws ua rau nws muaj peev xwm rau cov nroj tsuag kho dej khib nyiab los hloov los ntawm cov nroj tsuag siv hluav taws xob mus rau cov nroj tsuag ua hluav taws xob; Nws tsis yog tsuas yog lub zeem muag uas tso cai rau tib neeg los sim hloov cov neeg siv khoom hauv zej zog mus rau lub neej muaj kev vam meej.
