Hauv kev lag luam npias, kev kho dej khib nyiab yog txoj haujlwm nyuaj thiab nyuaj. Ib tug loj npaum li cas ntawm cov dej khib nyiab yog generated thaum lub sij hawm tsim npias txheej txheem, uas muaj siab concentrations ntawm cov organic teeb meem thiab cov as-ham. Nws yuav tsum tau ua ntej pretreatment ua ntej nws yuav ua tau zoo purified nyob rau hauv ib txwm siv dej khib nyiab kho nroj tsuag. Polyacrylamide (PAM), uas yog siab molecular-yuag polymer, tau dhau los ua kev daws teeb meem zoo rau kev kho dej khib nyiab hauv breweries. Kab lus no yuav tshawb xyuas seb PAM tuaj yeem txhim kho cov txheej txheem kho dej khib nyiab hauv breweries thiab pab txhawb kev txhim kho kom ruaj khov.
Cov yam ntxwv ntawm brewery khib nyiab
Npias tsim muaj ntau theem, suav nrog malt ua, sib tsoo, mashing, boiling, pom, hop ntxiv, fermentation, maturation, clarification thiab ntim. Cov dej khib nyiab los ntawm ntau qhov chaw yuav raug tsim nyob rau hauv cov txheej txheem no, feem ntau suav nrog:
- Ntxuav dej hauv cov txheej txheem malt
- Solidified ntxuav dej
- Ntxuav dej rau cov txheej txheem saccharification
- Fermentation tank ntxuav dej
- Cov kaus poom thiab lub raj mis ntxuav dej
- Cov dej txias
- Ntxuav dej hauv cov khoom ua tiav kev cob qhia
- Thiab qee qhov dej phwj hauv tsev
Cov dej khib nyiab no feem ntau muaj cov organic xws li cov proteins, poov xab, polysaccharides thiab cov nplej seem. Cov dej tsis zoo yog qhov nyuaj thiab kev kho mob nyuaj.
PAM Txhim Kho Kev Kho Cov Dej Num Li Cas hauv Breweries
Yuav Ua Li Cas Xaiv Polyacrylamide rau Brewery Wastewater Treatment
Hauv kev kho cov dej khib nyiab ntawm cov breweries, xaiv hom tsim nyog thiab ntau npaum li cas ntawm PAM yog qhov tseem ceeb heev. Txhawm rau ua tiav cov txiaj ntsig kev kho mob zoo tshaj plaws, nws yog qhov yuav tsum tau txiav txim siab qhov hnyav molecular, hom ion thiab ntau npaum li cas ntawm PAM los ntawm kev sim thiab kev sim ntawm qhov chaw ua ke nrog cov khoom tshwj xeeb thiab cov yam ntxwv zoo ntawm cov dej khib nyiab.
Cov yam tseem ceeb muaj xws li:
Hom kev tshem tawm cov khib nyiab hauv cov dej khib nyiab:Npias dej khib nyiab feem ntau muaj cov organic xws li cov proteins, poov xab, thiab polysaccharides, tshwj xeeb tshaj yog cov poov xab thiab malt proteins.
Tus nqi pH ntawm cov dej khib nyiab:Cov pH sib txawv ntawm cov dej khib nyiab tuaj yeem cuam tshuam rau kev ua haujlwm ntawm PAM.
Lub turbidity ntawm cov dej khib nyiab:Cov dej khib nyiab nrog siab turbidity yuav tsum tau siv ntau dua flocculants kom ntseeg tau tias kev ua haujlwm ntawm sedimentation.
PAM feem ntau muab faib ua peb hom: cationic, anionic thiab nonionic. Rau npias dej khib nyiab nrog cov ntsiab lus organic siab thiab cov nqi tsis zoo, siab-molecular-yuag cationic PAM feem ntau yog qhov kev xaiv zoo tshaj. Nws muaj peev xwm flocculation muaj peev xwm sai sai kho impurities thiab txhim kho kev ua haujlwm ntawm cov khoom tshem tawm.
Qhov ntau npaum ntawm PAM yog qhov tseem ceeb rau kev ua haujlwm ntawm cov dej khib nyiab. Ntxiv PAM ntau dhau tuaj yeem ua rau cov khoom pov tseg thiab cov sludge ntau dhau, thaum ntxiv me me yuav ua rau muaj kev kho mob tsis zoo. Yog li ntawd, kev tswj xyuas qhov ntau npaum li cas ntawm PAM yog qhov tseem ceeb heev.
Polyacrylamide (PAM) muaj cov txiaj ntsig zoo, kev lag luam thiab ib puag ncig zoo rau kev kho dej khib nyiab hauv breweries. Nws lub peev xwm los flocculate thiab coagulate suspended solids pab txhim kho cov dej zoo, pom kev ua haujlwm zoo thiab kev tswj dej khib nyiab. Yuncang tau mob siab rau muab cov tshuaj kho dej zoo kom tau raws li cov kev xav tau tshwj xeeb ntawm ntau yam kev lag luam, suav nrog breweries. Peb paub zoo txog kev xaiv hom thiab ntau npaum li cas ntawm PAM los xyuas kom meej qhov ua tau zoo tshaj plaws, txo cov nqi khiav lag luam thiab kev cuam tshuam ib puag ncig. Nrog rau peb cov kev pab txhawb nqa thiab hloov pauv cov kev daws teeb meem, peb pab peb cov neeg siv khoom kom ua tiav cov dej huv huv, txhim khu kev ruaj ntseg, thiab ua tau raws li cov qauv kev cai. Xaiv Yuncang kom tau txais kev ntseeg siab, raug nqi thiab ib puag ncig tus phooj ywg kev kho dej daws teeb meem.
