Dab tsi yog cov txheej txheem kho dej

Kev kho dej phwj tuaj feem ntau suav nrog kev kho peb theem hauv qab no: kev kho thawj theem yog tshem tawm pob zeb, xuab zeb thiab roj, hlau ions, manganese ions, roj, thiab lwm yam. Kev kho mob thib ob yog kev kho mob lom, uas cov pa phem hauv cov dej phwj tuaj yog degraded thiab hloov dua siab tshiab. nyob rau hauv sludge nyob rau hauv qhov kev txiav txim ntawm microorganisms. Tertiary kev kho mob yog kev kho mob siab heev ntawm cov dej phwj tuaj, uas suav nrog kev tshem tawm cov as-ham thiab tshuaj tua kab mob los ntawm chlorination, hluav taws xob ultraviolet lossis ozone technology. Nyob ntawm cov hom phiaj kev kho mob thiab dej zoo, qee qhov kev kho dej phwj tuaj tsis suav nrog tag nrho cov txheej txheem saum toj no.
Cov txheej txheem dej ntshiab yog nyob ntawm qhov zoo ntawm cov dej nyoos.
Yog tias cov dej nyoos yog dej hauv nroog, cov txheej txheem dav dav yog
Sand filter--activated carbon filter--softening (optional)--security filter--reverse osmosis--ultraviolet disinfection--cov khoom dej
Yog tias nws yog cov dej dav dav, nws yuav tsum tau ua kom tsis muaj menyuam thiab flocculant yuav tsum tau ntxiv ua ntej nkag mus rau cov txheej txheem saum toj no.
Yog tias nws yog dej zoo, ntxiv lub lim kom tshem tawm cov hlau thiab manganese tom qab xuab zeb pom.
Cov dej tau siv dua thiab ua kom huv.
Quartz xuab zeb pom yog ib qho zoo tshaj plaws ntawm kev tshem tawm cov khib nyiab pov tseg hauv dej, thiab yog ib qho tseem ceeb hauv kev kho dej phwj, dej phwj rov qab thiab kev kho dej. Nws txoj haujlwm yog txhawm rau tshem tawm cov pa phem ntxiv uas tau flocculated hauv dej. Nws ua tiav lub hom phiaj ntawm kev lim dej los ntawm kev cuam tshuam, sedimentation thiab adsorption ntawm cov khoom lim.
