Dab tsi yog qhov dej ntshiab pretreatment system?

Cov dej ntshiab huv pretreatment system yog ib qho chaw tshwj xeeb tsim los txhim kho cov dej zoo thiab tshem tawm cov impurities thiab cov kab mob. Nws yog dav siv nyob rau hauv industrial, kuaj, thiab haus dej ntau lawm txheej txheem. Nrog rau kev txhim kho thev naus laus zis thiab kev xav tau ntau ntxiv rau cov dej zoo, cov dej ntshiab pretreatment systems tau dhau los ua qhov tseem ceeb. Thaum lub sijhawm ua haujlwm, lub kaw lus feem ntau suav nrog ntau cov kauj ruam los xyuas kom meej tias cov dej zaum kawg ua tau raws li cov qauv siv siab.

Ua ntej, thawj kauj ruam hauv cov dej ntshiab pretreatment system yog coarse pom ntawm cov dej nyoos kom tshem tawm cov khib nyiab, av, thiab cov khoom loj. Tus yuam sij rau cov kauj ruam no yog xaiv cov khoom siv lim dej kom tsim nyog, xws li cov lim dej fiber ntau thiab cov xuab zeb lim, uas cuam tshuam cov khoom loj dua, yog li tiv thaiv cov khoom siv kho mob tom ntej. Tom qab ntawd, cov dej dhau los ntawm lub tank sedimentation ntxiv kom tshem tawm cov khib nyiab thiab cov sediment, txhim kho cov dej kom pom tseeb thiab meej.

Qhov thib ob, kev kho mob ntxiv yog ib feem tseem ceeb ntawm cov dej ntshiab pretreatment system. Los ntawm kev ntxiv tshuaj, impurities nyob rau hauv dej yog coagulated thiab tswm, ntxiv txo cov concentration ntawm cov teeb meem tshuaj. Kev siv tshuaj xws li tshuaj chlorine, ammonia, thiab polyferric sulfate zoo tshem tawm cov kab mob thiab cov kab mob hauv dej, tso lub hauv paus rau kev kho kom huv tom qab. Tsis tas li ntawd, cov pa roj carbon activated yog siv dav, tshem tawm cov organic teeb meem thiab ntxhiab tsw ntawm dej, txhim kho nws saj thiab zoo.

Tsis tas li ntawd, cov dej ntshiab pretreatment systems feem ntau yog nruab nrog rov qab osmosis units. Rov qab osmosis thev naus laus zis, nrog nws cov kev kho dej zoo tshaj plaws, ntxiv tshem tawm ions, ntsev, thiab lwm yam tshuaj yaj los ntawm cov dej, kom ntseeg tau tias muaj purity siab heev. Cov kauj ruam no yog siv dav hauv kev lag luam tshuaj, khoom siv hluav taws xob, thiab khoom noj khoom haus kom tau raws li lawv cov kev xav tau rau cov dej ntshiab huv siab.

Nyob rau hauv luv luv, dej ntshiab pretreatment systems ua kom huv si dej los ntawm ntau- theem kev kho mob, hais txog lub cev thiab lwm yam. Nrog rau kev paub txog ib puag ncig thiab dej tsis txaus, kev siv cov dej ntshiab pretreatment systems yuav dhau los ua ntau dua thiab tseem ceeb. Nws tsis yog tsuas yog txhawj xeeb txog kev nyab xeeb ntawm dej, tab sis kuj tseem ua lub luag haujlwm tseem ceeb hauv peb txoj kev loj hlob mus ntev. Los ntawm kev tshawb fawb thiab kev siv thev naus laus zis kho dej, peb tuaj yeem cia siab tias yuav ua kom muaj kev sib haum xeeb ntawm tib neeg thiab qhov xwm txheej, ua rau txhua tus poob dej thiab tiv thaiv peb ib puag ncig ecological.
