Municipal dej phwj
Hauv kev kho cov dej phwj hauv tsev, polyacrylamide tuaj yeem txhawb nqa kev sib txuas sai sai thiab kev sib haum xeeb ntawm kev ncua turbidity hais kom ua tiav cov txiaj ntsig ntawm kev sib cais thiab kev qhia meej los ntawm hluav taws xob neutralization thiab nws tus kheej adsorption bridging. Nws yog tsuas yog siv rau flocculation kev sib hais haum nyob rau hauv pem hauv ntej seem thiab sludge dewatering nyob rau hauv sab nraum qab ntawm cov dej phwj kho nroj tsuag.
Muaj dej khib nyiab
Thaum ntxiv polyacrylamide rau hauv cov dej ntawm cov khoom tshem tawm turbidity, nws tuaj yeem txhawb kev sib sau sai thiab kev sib haum xeeb ntawm kev tshem tawm turbidity hais los ntawm hluav taws xob neutralization thiab adsorption bridging nyhuv ntawm polymer nws tus kheej, thiab ua tiav cov txiaj ntsig ntawm kev sib cais thiab kev qhia meej, txhawm rau txhim kho cov khoom siv. kev khiav hauj lwm efficiency thiab txo tus nqi khiav hauj lwm.
Textile printing thiab dyeing kev lag luam
Raws li tus neeg sawv cev sizing thiab xov xov rau cov ntaub tom qab kev kho mob, polyacrylamide tuaj yeem tsim cov mos mos, wrinkle-proof thiab mildew tiv thaiv txheej. Nrog nws cov khoom muaj zog hygroscopic, nws tuaj yeem txo qhov tawg ntawm cov xov paj spinning. Nws tseem tiv thaiv hluav taws xob zoo li qub thiab nplaim hluav taws xob ntawm cov ntaub. Thaum siv los ua luam ntawv thiab dyeing auxiliaries, nws tuaj yeem txhim kho qhov adhesion ceev thiab ci ntsa iab ntawm cov khoom; Nws kuj tseem siv tau los ua cov tsis yog-silicon polymer stabilizer rau bleaching. Tsis tas li ntawd, nws tseem tuaj yeem siv rau kev ua kom huv ntawm textile printing thiab dyeing dej khib nyiab.
Ntawv ua kev lag luam
Polyacrylamide yog dav siv raws li kev tuav tuav, pab lim thiab dispersant hauv papermaking. Nws txoj haujlwm yog txhawm rau txhim kho cov ntawv zoo, txhim kho lub cev qhuav dej ntawm slurry, txhim kho tus nqi khaws cia ntawm cov fibers zoo thiab muab tub lim, txo cov khoom siv raw thiab ib puag ncig muaj kuab paug. Cov nyhuv ntawm nws siv nyob rau hauv papermaking nyob ntawm seb nws qhov nruab nrab molecular hnyav, ionic zog, ionic zog thiab cov hauj lwm ntawm lwm copolymer. Nonionic PAM feem ntau yog siv los txhim kho cov cuab yeej lim dej ntawm cov ntaub so ntswg, ua kom lub zog ntawm cov ntawv qhuav, txhim kho tus nqi tuav ntawm fiber ntau thiab muab tub lim; Anionic copolymer feem ntau yog siv los ua tus neeg sawv cev qhuav thiab ntub dej thiab cov neeg nyob hauv daim ntawv. Cov cationic copolymer feem ntau yog siv rau kev kho mob ntawm papermaking wastewater thiab pom kev pab, thiab nws kuj muaj txiaj ntsig zoo rau kev txhim kho tus nqi tuav ntawm cov muab tub lim. Tsis tas li ntawd, PAM kuj tseem siv rau hauv kev kho cov dej khib nyiab thiab cov fiber ntau rov qab.
Kev lag luam thee
Coal ntxuav cov dej khib nyiab, thee npaj cog slime dej, thee fais fab nroj tsuag hauv av ntxuav cov dej khib nyiab, thiab lwm yam, yog cov dej sib tov thiab cov hmoov zoo hmoov, nws cov yam ntxwv tseem ceeb yog siab turbidity, nplua particle loj ntawm cov khoom hais, qhov chaw ntawm cov khoom siv yog ntau qhov tsis zoo, lub zog quab yuam ntawm tib tus nqi ua rau cov khoom no nyob twj ywm hauv dej, cuam tshuam los ntawm lub ntiajteb txawj nqus thiab Brownian motion; Vim muaj kev sib cuam tshuam ntawm cov khoom sib txuas ntawm cov khoom siv hauv cov coal slime dej, cov khoom ntawm cov thee ntxuav cov dej khib nyiab yog qhov nyuaj, uas tsis tsuas yog muaj cov khoom ntawm kev ncua, tab sis kuj muaj cov khoom ntawm colloidal. Yuav kom cov thee slime dej precipitate sai sai nyob rau hauv lub concentrator, xyuas kom meej lub tsim nyog ntxuav dej thiab siab lim thee slime ntau lawm, thiab ua kom cov ntau lawm npaum thiab kev lag luam, nws yog tsim nyog los xaiv qhov tsim nyog flocculant ntxiv dag zog rau kev kho mob ntawm thee slime. dej. Lub series ntawm polymer flocculation dehydrating tus neeg sawv cev tsim rau thee slime dewatering nyob rau hauv thee ntxhua khaub ncaws muaj siab dewatering efficiency thiab yog ib qho yooj yim mus use.
Hluav taws xob thiab electroplating kev lag luam
Cov txheej txheem kev kho mob feem ntau yog kho tus nqi pH ntawm cov dej khib nyiab nrog sulfuric acid rau 2 ~ 3 hauv thawj cov tshuaj tiv thaiv tank, tom qab ntawd ntxiv cov tshuaj txo qis, kho tus nqi pH nrog NaOH lossis Ca (OH) 2 txog 7 ~ 8 hauv cov tshuaj tiv thaiv tom ntej. tank los tsim Cr(OH)3 nag lossis daus, thiab tom qab ntawd ntxiv coagulant kom tshem tawm Cr(OH)3 nag lossis daus.
Steel ua tsob nroj
Nws yog tsuas yog siv los ntxuav cov dej khib nyiab los ntawm cov pa roj flue ntawm cov pa oxygen tshuab converter, uas feem ntau hu ua cov plua plav tshem tawm cov dej khib nyiab ntawm lub converter.
