Niaj hnub no, tib neeg txoj kev paub txog ib puag ncig yog maj mam nce, thiab kev hu rau kev tiv thaiv ib puag ncig tau nrov thiab nrov. Nyob rau hauv cov txheej txheem ntawm kev lag luam, yuav muaj ntau cov dej khib nyiab, dej phwj tuaj, dej lom, thiab lwm yam, uas yuav tsum tau kho los ntawm kev tshwj xeeb. Yog tias tsis kho kom raug, nws yooj yim ua rau muaj kuab paug ib puag ncig, thiab tseem cuam tshuam rau thaj chaw nyob ze. rau tib neeg cov teeb meem kev noj qab haus huv. Yog li yuav ua li cas cov tshuab hluav taws xob ua haujlwm nrog cov teeb meem sib kis no?
Piv txwv li, electronics Hoobkas dej purification. Raws li cov khoom siv hluav taws xob sib txawv, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob yuav tsum tau muab ntxuav thaum lub sij hawm tsim khoom. Thaum lub sijhawm ntxuav, cov dej khib nyiab loj yuav tshwm sim. Cov dej khib nyiab no muaj ntau cov tin, lead, thiab cyanide. Cov tshuaj, hexavalent chromium, trivalent chromium, thiab lwm yam, thiab cov dej khib nyiab organic kuj tseem nyuaj thiab yuav tsum tau kho nruj ua ntej nws tuaj yeem tso tawm. Yuav kom daws tau qhov teeb meem no, qee lub tuam txhab hluav taws xob yuav siv cov tshuab hluav taws xob ua hluav taws xob los ua peb qhov cuam tshuam evaporation los ntxuav cov dej paug.
Thaum lub tshuab hluav taws xob peb-txheej txheem evaporator khiav, yuav tsum muaj lub tshuab hluav taws xob ua hluav taws xob los muab lub zog cua sov thiab siab. Nyob rau hauv lub xeev ntawm circulating cua txias, qhov thib ob chav ua los ntawm cov khoom siv dej khib nyiab yuav raug hloov mus rau hauv cov dej condensed, thiab cov dej condensed tuaj yeem txuas ntxiv Cov dej tawm thiab rov ua dua tshiab rau hauv lub pas dej. Txoj kev no tsuas yog ua tiav los ntawm chav generators. Thaum ua haujlwm peb-txhim kho cov dej phwj tuaj, qhov ntim ntim txaus thiab cov khoom siv txuas ntxiv ntawm cov chav yuav tsum tau ua, thiab lub tshuab hluav taws xob tuaj yeem ua haujlwm 24 teev hauv ib hnub yam tsis muaj cov khoom pov tseg. Qhov seem tso pa tawm thiab dej pov tseg.
Qhov tseeb, dej muaj kuab paug yog txaus ntshai heev, tshwj xeeb tshaj yog ua ntej industrialization tsis yog li ntawd. Cov dej hauv tus dej tau haus ncaj qha. Nws qab qab thiab qab heev. Koj tseem tuaj yeem pom tias cov dej hauv tus dej yog qhov tseeb tshwj xeeb. Tab sis niaj hnub no cov dej hauv dej muaj ntau cov hlau hnyav thiab lwm yam tshuaj lom, cov ntsiab lus ntawm lub rooj zaum ntawm cov ntsiab lus tuaj yeem pom nyob rau hauv cov dej ntws, thiab dej muaj kuab paug tshwj xeeb.
Niaj hnub no, nyob rau hauv kev tswj hwm nruj ntawm tsoomfwv, qhov xwm txheej dej paug yuav daws tau zoo. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho ntawm tib neeg ib puag ncig kev paub, tib neeg yuav ceev faj txog kev kho cov dej phwj tuaj thiab cov dej khib nyiab.
Lub tshuab hluav taws xob tuaj yeem siv tsis tau tsuas yog siv peb lub evaporator los ntxuav cov dej phwj tuaj, tab sis kuj siv lub tshuab nqus tsev vacuum thiab concentration kom evaporate cov dej phwj tuaj rau hauv cov pa roj thiab cov pa phem. Nws tseem tuaj yeem ua tiav cov txheej txheem distillation thiab condensation, cia cov roj evaporated yuav tsum tau ua kua thiab distilled cais, thiab cov dej sib cais yuav tsum tau condensed, thiab tom qab ntawd 90% ntawm cov dej distilled tuaj yeem rov qab siv dua. Nws tseem tuaj yeem mloog cov pa phem. Tom qab cov dej phwj tuaj evaporated, cov kuab paug seem yog cov pa phem. Lub sijhawm no, nws tuaj yeem ua kom muaj zog thiab tom qab ntawd cov pa phem tuaj yeem tawm mus.
