Zeolite
Kev lag luam xab npum yog qhov loj tshaj plaws thov teb ntawm cov khoom siv hluav taws xob. In the 1970 s, the ecological environment deteriorated because the use of sodium triphosphate seriously polluted the water body. Tawm ntawm kev tiv thaiv ib puag ncig, cov neeg pib nrhiav lwm tus neeg ntxuav kev ntxuav AIDS. Tom qab cov ntaub ntawv pov thawj, hluavtolet zeolite muaj qhov muaj zog muaj peev xwm rau CA2 +, thiab tseem ua cov dej num los nag nrog cov av insoluble, pab txhawb kom tshem tawm. Nws muaj pes tsawg leeg yog zoo li cov av, tsis muaj kuab paug rau ib puag ncig, tab sis kuj muaj kev cuam tshuam lossis mob carinogenic, thiab tsis muaj kev phom sij rau tib neeg kev noj qab haus huv ".
Dej qab zib tshauv
Ua ntej cov khoom siv dag zog ntawm dej qab zib, nws tau pom tias tom qab qee lub seaweed tau ziab, cov ntoo uas tawg, thiab tuaj yeem so hauv dej kub kom huv. Lub luag haujlwm ntawm cov dej qab zib hauv kev ntxhua khaub ncaws hmoov yog raws li hauv qab no:
1. Dej qab zib ua tej uas lub luag haujlwm tsis muaj lub luag hauj lwm. Thaum ntxuav, dej qab zib yuav tsim cov sodium silica nrog qee cov tshuaj, uas ua rau cov tshuaj lom zem, yog li nws tuaj yeem txo cov xab xab npum.
2. Cov nyhuv ntawm cov tshauv
3. Dej qab zib tshauv nyob rau hauv kev ntxhua khaub ncaws, muaj qee yam kev tiv thaiv cuam tshuam ntawm cov ntaub.
4. Cov nyhuv ntawm dej qab zib tshauv ntawm cov khoom ntawm pulp thiab ntxhua hmoov. Sodium silicate tuaj yeem tswj lub fluurry ntawm slurry, tab sis kuj tseem tuaj yeem txhim kho cov khoom siv ntxhua, txhim kho cov solubility ntawm cov khoom tiav, tso cov khaub ncaws tiav pob zeb.
5. Dej qab cov tshauv ua si ib qho kev tawm tsam tiv thaiv corrosion, sodium soliabion tuaj yeem tiv thaiv Phosphate thiab lwm yam tshuaj ntawm cov hlau, thiab tiv thaiv kev tiv thaiv tsis ncaj.
6, nrog cov nyhuv ntawm cov sodium carbonate, nws sodium carbonate nrog hnoos muag muag tau nyuaj, uas tuaj yeem tshem cov ntsev ntau hauv cov dej.

Dej nyab
Roj-dej cais cov qauv siv cov roj-cov ntaub ntawv ua phooj ywg kom nqus cov roj yaj thiab lwm cov organic sib xyaw ua ke hauv cov khoom siv dej wastewater. Cov roj siv feem ntau siv cov khoom siv uas nquag ua cov roj av uas tsis muaj roj, roj tawg thiab yaj roj hauv dej. Vim tias qhov muaj peev xwm tsawg ntawm cov pa roj carbon ntau (feem ntau 30 ~ 80mg / g)), muaj nuj nqis ntawm cov roj av, thiab feem ntau yog siv rau cov roj av theem kawg nkaus xwb [6]
Vim tias tau txais cov pa roj carbon kom ua tau zoo ntawm cov dej thiab kim ua haujlwm rau cov pa roj carbon ntau yog tsuas yog siv cov penpon feem ntau yog siv los ua kom tiav cov kuab paug hauv dej kom ua tiav lub hom phiaj ntawm kev lim dej tob.
