Industrial Wastewater Treatment
Kev kho dej khib nyiab suav nrog cov txheej txheem thiab cov txheej txheem siv los kho cov dej uas tau kis kab mob hauv qee txoj kev los ntawm anthropogenic kev lag luam lossis kev lag luam ua ntej nws tso tawm rau hauv ib puag ncig lossis rov siv dua.
Feem ntau cov kev lag luam tsim cov khib nyiab ntub dej txawm hais tias tsis ntev los no cov kev hloov hauv lub ntiaj teb tsim tau los txo cov kev tsim khoom lossis rov ua dua cov khoom pov tseg hauv cov txheej txheem tsim khoom. Txawm li cas los xij, ntau qhov kev lag luam tseem nyob ntawm cov txheej txheem uas tsim cov dej khib nyiab.
Qhov chaw ntawm industrial wastewater
-
Agricultural pov tseg
- Breweries
- Kev lag luam mis nyuj
- Ua liaj ua teb
- Pulp thiab Ntawv kev lag luam
Kev tsim cov ntawv yog ib qho peev txheej, lub zog thiab dej siv kev lag luam. Nws kuj yog ib txoj kev ua qias tuaj heev thiab yuav tsum tau nqis peev ntau rau hauv cov khoom siv tswj cov pa phem.
- Hlau thiab steel kev lag luam
Kev tsim cov hlau los ntawm nws cov ores cuam tshuam nrog kev txo qis hauv cov tshuab tawg. Cov dej txias yog inevitably paug nrog cov khoom tshwj xeeb tshaj yog ammonia thiab cyanide.
- Mines thiab quarries
Cov dej khib nyiab los ntawm cov hlau mines thiab cov ore rov qab cov nroj tsuag yog inevitably paug los ntawm cov zaub mov uas muaj nyob rau hauv cov pob zeb tsim.
- Kev lag luam zaub mov
Kev ua zaub mov rau kev muag khoom tsim cov khoom pov tseg uas tau tsim los ntawm kev ua noj uas feem ntau nplua nuj nyob rau hauv cov nroj tsuag organic thiab tej zaum kuj muaj ntsev, flavourings, colouring material thiab acids los yog alkali.
