Puas tuaj yeem rov qab osmosis daim nyias nyias tuaj yeem rov ua dua tom qab hloov?

Feem ntau hais lus, rov qab osmosis daim nyias nyias tuaj yeem ntxuav.

Caustic soda thiab hydrochloric acid feem ntau yog siv hauv kev lag luam, thiab cov khoom siv tshwj xeeb offline yog siv rau ntawm qhov kub thiab txias. Cov txheej txheem yuav tsum ntxuav nrog caustic soda ua ntej, tom qab ntawd nrog caustic soda, thiab soaking rau lub sij hawm ntev. Lub complexity ntawm cov txheej txheem yog dhau qhov kev txawj ntse ntawm cov neeg zoo tib yam.

Yog li nws tsis pom zoo kom ntxuav tsev neeg rov qab osmosis membrane, vim nws nyuaj heev thiab tsis yooj yim los ntxuav.

Txoj kev ntxuav

1. Enzyme detergent yog siv los kho cov daim nyias nyias, uas yog tshwj xeeb tshaj yog tiv thaiv cov organic kuab paug, tshwj xeeb tshaj yog cov protein, roj thiab lwm yam kuab paug organic. Cov nyhuv ntxuav yog zoo dua ntawm 50-60 ℃. Feem ntau, tom qab khiav rau 10 hnub lossis ib nrab ib hlis, 1% enzyme detergent yog siv los ntxuav cov daim nyias nyias nyob rau hauv qis qis. Vim tias qhov tsis tshua muaj siab ntawm enzyme detergent siv, yuav tsum tau siv sijhawm ntev dua.
2. Citric acid tov yog siv los ua kom tsis tu ncua lossis cyclically yaug daim nyias nyias nrog 1% -2% citric acid aqueous tov nyob rau hauv siab los yog tsis tshua muaj siab, uas muaj ib tug zoo tu nyhuv ntawm Fe (OH) 3 pa phem.
3. Concentrated saline kua yog siv tau rau kev ntxuav cov daim nyias nyias nrog cov pa phem heev. Qhov no yog vim hais tias cov kua ntsev ntau ntau tuaj yeem ua rau tsis muaj kev cuam tshuam ntawm colloids thiab txhawb kev tsim cov colloidal aggregates.
4. Hydrogen peroxide tov, piv txwv li, diluting 0.5L ntawm 30% H2O2 nrog 12L ntawm deionized dej thiab tom qab ntawd ntxuav lub membrane nto, tshwj xeeb tshaj yog zoo tiv thaiv cov organic pollution.
5. Dej soluble emulsion yog qhov zoo heev rau kev ntxuav cov kab mob ntawm cov roj thiab cov hlau oxide, feem ntau ntxuav rau 30-60 feeb.
6. Txoj kev tu lub cev uas yooj yim tshaj plaws yog siv lub zog qis thiab cov dej ntws nrawm nrawm ntawm cov dej ntws yaug rau 30 feeb, uas tuaj yeem rov qab kho cov permeability ntawm daim nyias nyias mus rau qee yam. Txawm li cas los xij, dhau sijhawm, qhov permeability tseem txo qis. Tsis tas li ntawd, kev sib xyaw ntawm dej thiab cua tuaj yeem siv los txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau 15 feeb. Txoj kev no siv tau zoo rau kev ntxuav daim nyias nyias uas tau pib kis nrog cov organic teeb meem.

Puas muaj tus qauv tshwj xeeb rau kev hloov pauv rov qab osmosis membranes?

Feem ntau hais lus, tom qab lub sijhawm siv, cov dej tsim tawm ntawm daim nyias nyias yuav txo qis, cov dej ntau lawm siab yuav nce, thiab cov conductivity ntawm daim nyias nyias yuav cuam tshuam. Thaum cov teeb meem no tshwm sim, koj daim nyias nyias tuaj yeem raug ntxuav lossis hloov pauv.

Yog hais tias lub siab thiab dej ntau lawm ntawm rov qab osmosis membrane tom qab ntxuav tau raws li qhov yuav tsum tau, nws yog txaus, tab sis cov conductivity feem ntau tsis txo, tshwj tsis yog tias lub membrane yog hnyav heev los ntawm cov organic teeb meem, vim hais tias lub pore loj nce nrog ntxuav, thiab txawm yuav siv cov tshuaj zoo li cas, cov dej ntau lawm thiab siab tom qab ntxuav yuav tsis zoo ib yam li ib tug tshiab daim nyias nyias.

Yaug cov membrane tshiab

1. Tom qab kev txhim kho cov txheej txheem membrane, cov txheej txheem tshiab yuav tsum tau muab yaug kom huv si kom tshem tawm cov khoom seem, cov kuab tshuaj, thiab cov dej tiv thaiv los ntawm lub cev.
2. Thaum siv cov dej uas tsim los rau haus, nws yuav tsum tau yaug kom tsawg li 24 teev.
3. Ua ntej pib lub kaw lus, cov dej concentrated valve yuav tsum qhib tag nrho. Tom qab lub kaw lus pib, cov dej concentrated valve tuaj yeem maj mam thiab maj mam kaw kom ua tiav cov txheej txheem rov qab. Nws yog nruj me ntsis txwv tsis pub pib cov cuab yeej thaum lub concentrated dej valve raug kaw.
4. Thaum lub sijhawm ua haujlwm ntawm lub kaw lus, li qub ntawm cov kav dej yuav tsum tsis txhob raug kaw txhua lub sijhawm (xws li pib ua ntej, kev ua haujlwm niaj hnub, dej ntws tawm, thiab tshuaj ntxuav lub cev).
5. Ua ntej kev ua haujlwm siab, ua kom tsis tshua muaj dej ntws los ntawm lub tshuab pib muag muag lossis kev tswj xyuas qhov nrawm nrawm kom tshem tawm cov huab cua.
