Cov khoom siv kho dej khib nyiab siab siab rau cov lag luam kom txuag tau cov nqi thiab txhim kho kev siv cov peev txheej

Nrog rau kev sib sib zog nqus ntawm industrialization, tshuaj, tshuaj, luam ntawv thiab dyeing, ntawv ua thiab lwm yam kev lag luam yog tsim tsis tu ncua. Txawm li cas los xij, ntau cov tshuaj thiab cov khoom siv raw yog siv rau hauv cov txheej txheem tsim khoom ntawm cov kev lag luam, thiab cov tshuaj no tuaj yeem cuam tshuam nrog dej thaum lub sijhawm tsim khoom los tsim cov dej khib nyiab uas muaj cov pa phem ntau. Vim tias muaj cov pa phem ntau hauv cov dej khib nyiab siab, cov kev kho ib txwm siv feem ntau nyuaj rau kev tshem tawm, yog li cov khoom siv tshwj xeeb high-concentration wastewater kho yog xav tau.
Kev kho cov dej khib nyiab siab yog qhov tsim nyog heev vim tias hom dej khib nyiab no muaj ntau yam tshuaj lom thiab muaj kev phom sij, uas yuav ua rau muaj kev puas tsuaj loj rau ecological ib puag ncig yog tias nws ncaj qha tawm mus rau ib puag ncig. Tsis tas li ntawd, cov dej khib nyiab siab tuaj yeem ua rau muaj kev hem thawj rau tib neeg kev noj qab haus huv thiab tuaj yeem ua rau muaj ntau yam kab mob.
Cov kev kho lub cev muaj xws li cov txheej txheem xws li sedimentation, pom thiab centrifugal sib cais kom tshem tawm cov khoom raug tshem tawm thiab cov khoom siv los ntawm cov dej khib nyiab. Txoj kev kho tshuaj, ntawm qhov tod tes, siv cov tshuaj tiv thaiv los ua kom tsis zoo lossis tshem tawm cov khoom phom sij hauv cov dej khib nyiab, xws li acid-base neutralization thiab oxidation-txo. Cov kev kho mob lom neeg siv cov metabolism hauv cov kab mob kom decompose organic teeb meem rau hauv cov khoom tsis zoo.
Daim ntawv thov cov khoom siv kho cov dej khib nyiab siab tsis tsuas yog pab tiv thaiv ib puag ncig, tab sis kuj txuag cov nqi rau cov lag luam. Los ntawm kev kho kom zoo ntawm cov dej khib nyiab, nws tuaj yeem txo qhov kev lag luam cov dej phwj tuaj, thiab tib lub sijhawm, rov qab tau cov peev txheej tseem ceeb hauv cov dej khib nyiab thiab txhim kho kev siv cov peev txheej.
Hauv luv luv, cov khoom siv kho dej khib nyiab siab yog qhov tseem ceeb rau kev tiv thaiv ib puag ncig thiab txhawb kev txhim kho kom ruaj khov. Nrog kev txhim kho txuas ntxiv ntawm kev paub txog kev tiv thaiv ib puag ncig, cov cuab yeej zoo li no yuav siv dav hauv ntau thaj chaw.
