Yam Tseem Ceeb:
Ua ntej, muaj cov khoom siv hluav taws xob.
Qhov thib ob, qhov concentration nce mus txog qhov txwv tsis pub tawg.
Thib peb, kom ncav cuag qhov hluav taws kub.
Tshuaj thiab tshuaj tua kab ntau lawm lag luam ntawm ntau yam, dej khib nyiab zoo complex.
Cov yam ntxwv tseem ceeb muaj xws li: siab concentration ntawm cov pa phem, COD (chemical oxygen xav tau) txog li kaum txhiab milligrams ib liter.
Ntxiv rau cov tshuaj tua kab thiab cov khoom nruab nrab, cov dej khib nyiab kuj muaj cov tshuaj lom xws li phenol, arsenic, mercury thiab ntau yam biodegradable, nrog rau cov ntxhiab tsw phem.
Nyob rau hauv tus txheej txheem ntawm kev kho dej khib nyiab, cov roj combustible uas tsim los ntawm anaerobic, tov nrog cov organic gases xws li benzene thiab aniline volatilized nyob rau hauv cov dej khib nyiab, yuav tawg yog tias tsis ua kom zoo.
Kev cuam tshuam:
Ua ntej, cov txheej txheem tawg tuaj yeem tsim cov pa phem thiab cov pa phem, yuav cuam tshuam rau qhov zoo ntawm cov huab cua puag ncig.
Qhov thib ob, cov txheej txheem pov tseg tawg uas muaj cov pa phem hauv cov hluav taws tua hluav taws tuaj yeem nkag mus rau hauv cov dej nyob ib puag ncig, cov dej hauv qab ib puag ncig.
Thib peb, ib qho loj ntawm cov khoom khib nyiab tsim tom qab tawg, tej zaum yuav yog ib feem ntawm cov khoom pov tseg, yuav tsum tau muab pov tseg kom zoo.
