lub teeb yuag, yooj yim tuav, tsis tshua muaj zog tsim kho, kev nce qib sai, tuaj yeem txuag cov nqi tsim kho:
Qhov ceev ntawm PVC-U yeeb nkab yog li 1400kg / m3, uas tsuas yog 1/5 ntawm cov yeeb nkab hlau cam khwb cia thiab 1/3 ntawm cov yeeb nkab pob zeb, thiab tus nqi tsim kho tuaj yeem txo tau 30% -50% piv rau cov yeeb nkab ib txwm muaj.

Cov khoom siv nanofiltration membrane hauv tsev muaj cov txiaj ntsig zoo kawg nkaus. Lawv muaj cov dej ntws ceev ceev hauv qab qhov siab qis, ua kom muaj dej txaus. Nrog rau cov peev xwm tshem tawm cov pa phem, lawv tuaj yeem tshem tawm cov organic macromolecular, cov hlau hnyav, thiab cov ntsev divalent. Cov khoom no kuj pheej yig, tsim nyog rau ntau yam kev siv suav nrog cov chaw faib dej hauv tsev kawm ntawv, thiab paub txog lawv cov khoom zoo.

Cov khoom siv kho dej phwj hauv tsev ntse uas sib xyaw ua ke muaj cov haujlwm tshem tawm nitrogen thiab phosphorus. Los ntawm kev sib xyaw ua ke cov thev naus laus zis sib cais membrane thiab txoj kev sib cuag oxidation, nrog rau kev siv cov kev tswj hwm ntse tag nrho, lub kaw lus ua tiav kev ua haujlwm tsis muaj neeg tsav tsheb thiab kev tswj hwm ntse. Nws yog kev sib xyaw ua ke zoo heev, ntse thiab txhim khu kev qha thiab tuaj yeem teeb tsa tau yooj yim rau hauv av lossis faus hauv av. Qhov zoo ntawm cov dej tsim tawm yog ruaj khov thiab tuaj yeem ua tau raws li thawj-chav kawm A tus qauv tso tawm.

Kev siv tshuab sib cais membrane ultra-filtration yog ib qho thev naus laus zis sib cais siab tsim nyob rau hauv xyoo tas los no; raws li qhov loj me ntawm molecular lossis particle, nws yog ib qho thev naus laus zis dynamic cross-flow filtration siv lub siab ua lub zog kom lub kaw lus khiav.

Cov khoom siv desalination dej hiav txwv yog cov khoom siv tshwj xeeb siv los desalinate dej hiav txwv. Seawater desalination feem ntau siv ob txoj hauv kev los desalinate dej hiav txwv, uas yog txoj kev distillation thiab txoj kev reverse osmosis.

Cov khoom siv ua kom dej mos ntawm lub boiler yog cov khoom siv ua ntej kho dej nyoos rau lub boiler ntev, uas tshem tawm cov calcium thiab magnesium ions hauv dej nyoos thiab cov ntsiab lus uas ua rau lub boiler ntev.

Cov txheej txheem kho dej phwj tseem ceeb ntawm kev luam ntawv thiab zas xim yog cov txheej txheem lub cev, tshuaj lom neeg thiab electrolysis. Cov txheej txheem tshuaj lom neeg thiab lub cev feem ntau sib xyaw ua ke kom tau txais txiaj ntsig zoo dua. Hauv txoj kev lub cev, qhov feem ntau siv yog adsorption, thiab cov txheej txheem tshuaj lom neeg feem ntau yog coagulation thiab oxidation.

Siv lub hauv paus ntsiab lus rov qab osmosis, cov khoom siv rov qab osmosis yog cov khoom siv uas siv cov thev naus laus zis sib cais membrane kom cov tshuaj mus dhau ntawm daim nyias nyias osmosis thiab cais cov kuab tshuaj rau cov tshuaj.
