Thaum lub caij ntuj no ua haujlwm ntawm lub tank dej ntawm cov nroj tsuag dej, ib txheej ntawm cov khoom zoo ib yam li PAC cov neeg ua haujlwm yuav ntab rau ntawm ntau cov dej cog qoob loo. Cov tshuaj no tsis nyob twj ywm thiab ntab mus rau saum npoo ntawm lub pas dej, uas cuam tshuam rau cov dej zoo thiab cov tsos. Cov khoom ntab tuaj yeem tshwm sim los ntawm ntau yam.
Kev siv tsis raug ntawm flocculants
1. Kev sib ntxiv ntawm PAC ntau dhau: Kev sib ntxiv ntawm flocculants ntau dhau yuav ua rau cov paj alum ntab, cuam tshuam rau cov nyhuv sedimentation.
2. Tus nqi pH tsis zoo: tus nqi pH tsawg dhau ntawm cov dej yuav cuam tshuam cov nyhuv ntawm flocculants thiab ua rau alum paj ntab.
3. Hydraulic scouring: Cov khoom siv hydraulic ntau dhau thiab cov dej ntws nrawm dhau yuav cuam tshuam cov av thiab ua rau nws ntab.
Cov dej tsis zoo thiab kub hloov pauv
1. Cov dej tsis zoo hloov pauv: Cov kev hloov pauv hauv cov ntsiab lus ntawm impurities xws li tshem tawm cov teeb meem thiab roj hauv cov dej nyoos yuav cuam tshuam rau cov nyhuv flocculation thiab ua rau cov khoom ntab tau tsim.
2. Kev hloov pauv kub: Kev hloov pauv hauv dej kub yuav cuam tshuam rau kev ua haujlwm ntawm cov kab mob thiab cov nyhuv ntawm cov tshuaj tiv thaiv flocculant.
Sedimentation tank tsim teeb meem
1. Sedimentation tank hom xaiv: Ntau hom sedimentation tank yog tsim rau cov dej zoo sib txawv. Kev xaiv tsis raug yuav cuam tshuam rau cov nyhuv sedimentation.
2. Sedimentation tank qauv tsim: cov qauv tsim tsis tsim nyog ntawm cov sedimentation tank, xws li kev tsim tsis zoo ntawm cov phaj inclined lossis inclined raj, yuav cuam tshuam rau cov nyhuv sedimentation.
Cov teeb meem kev ua haujlwm thiab kev tswj xyuas
1. Cov sludge tawm tsis raws sij hawm: Yog tias cov sludge hauv qab hauv qab lub tank tsis tawm hauv lub sijhawm, nws yuav ua rau hauv qab ntawm lub tank, cuam tshuam rau cov nyhuv sedimentation.
2. Tsis sib xws flocculant ntxiv: Tsis sib xws flocculant ntxiv yuav ua rau ntau lub zos concentration, tsim alum paj ntab.
PAC tus neeg saib xyuas cov tshuaj tiv thaiv kab mob
1. Cov nyhuv Counterion: Cov counterions hauv dej ua rau cov flocculant, ua rau cov nyhuv flocculation tsis zoo thiab tsim cov khoom ntab.
2. Flocculant zoo teeb meem: Cov teeb meem zoo ntawm flocculant nws tus kheej kuj yuav ua rau cov nyhuv flocculation tsis zoo thiab tsim cov khoom ntab.
Environmental yam
1. Kev cuam tshuam tom qab los nag hnyav: Tom qab los nag hnyav, qhov loj ntawm cov khoom ntab ntab yuav tawg los ntawm cov nag thiab ntws mus rau tom qab kawg nrog cov dej ntws, txo cov khoom ntab hauv cheeb tsam sedimentation.
Kev tu cov cuab yeej siv tsis txaus
1. Kev laus cov khoom siv: Yog tias cov khoom siv hauv lub tank sedimentation tsis tau khaws cia ntev, nws yuav ua tsis tiav thiab cuam tshuam rau cov nyhuv sedimentation.
2. Kev tu tsis tu ncua: Cov phaj inclined lossis cov raj inclined hauv lub tank sedimentation yuav tsum tau ntxuav tsis tu ncua, txwv tsis pub cov sedimentation yuav cuam tshuam.
Cov lus qhia thiab kev daws teeb meem
1. Ua kom zoo dua flocculant ntxiv: Kho qhov ntau npaum li cas thiab pH tus nqi ntawm flocculants raws li kev hloov pauv hauv dej kom ntseeg tau tias cov flocculants tuaj yeem ua tiav lawv lub luag haujlwm.
2. Txhim kho sludge tswj: tsis tu ncua tso cov sludge, tswj sludge concentration, thiab tsis txhob sludge ntab.
3. Txhim kho sedimentation tank tsim: Xaiv qhov tsim nyog sedimentation tank hom raws li kev kho dej zoo thiab optimize cov sedimentation tank qauv tsim.
4. Txhim kho qib ntawm kev tswj xyuas kev ua haujlwm: Txhim kho kev tswj hwm txhua hnub thiab kev saib xyuas ntawm lub tank sedimentation kom ntseeg tau tias kev ua haujlwm zoo ntawm cov khoom siv.
5. Teb cov kev hloov pauv dej zoo: Ua tib zoo saib xyuas cov kev hloov pauv hauv cov dej tsis zoo thiab kho cov txheej txheem kho raws sijhawm.
6. Siv cov khoom ib puag ncig: Tom qab cua daj cua dub, siv cov dej nag ntuj los pab ntxuav cov khoom uas ntab saum npoo ntawm cov dej khib nyiab.
