Kev soj ntsuam ntawm cov laj thawj rau qhov nyuaj ntawm kev ruaj khov thiab tsim nyog kev kho mob ntawm Electroplating Wastewater los ntawm Hluav Taws Kub Kub Tubes
Electroplating yog ib feem tseem ceeb ntawm kev tsim khoom, tab sis nws yog ib qho kev lag luam uas muaj kuab paug ntau heev. Cov khoom xws li cov hlau hnyav ions thiab cov organic sib txuas hauv cov dej khib nyiab electroplating ua rau muaj kev phom sij loj heev. Raws li cov kev xav tau sib txawv rau kev ua haujlwm, kev tiv thaiv corrosion, thiab cov khoom siv zoo nkauj ntawm cov txheej txheem electroplating, qib kev tswj hwm, cov txheej txheem electroplating, thiab cov tshuaj siv hauv cov chaw ua haujlwm sib txawv heev, thiab qhov sib txawv ntawm cov dej khib nyiab tuaj yeem sib txawv heev, kev kho cov dej khib nyiab. yuav hloov tau. Kev ua tau zoo ntawm electroplating wastewater kho yog qhov tseem ceeb ncaj qha ntsig txog cov khoom siv tshuaj lom neeg ntawm cov tshuaj muaj nyob hauv cov dej khib nyiab. Kab lus no npaj siab los tshuaj xyuas cov laj thawj uas yuav ua rau cov dej khib nyiab tsis zoo, thiab cia siab tias yuav pab txhawb kev lag luam thiab kev ntseeg siab ntawm kev kho cov dej khib nyiab ruaj khov thiab qauv.
1. Kev faib tawm thiab tshuaj kho cov txheej txheem ntawm Electroplating Wastewater
Muaj ntau txoj kev kho mob zoo rau cov dej khib nyiab electroplating: chemical method, physiotherapy method, Physical chemical method, biological method, etc. Hauv cov teb chaws tsim kho xws li Tebchaws Meskas, thaum ntxov li xyoo 1960, ion exchange resin, electrolysis, electrodialysis, thim rov qab osmosis. , zaj duab xis evaporation thiab lwm yam khoom siv tau zoo tsim thiab siv. Tab sis txhua txoj kev kho dej khib nyiab electroplating muaj nws qhov zoo, qhov tsis zoo, thiab siv tau. Piv txwv li, electroplating precious hlau khib nyiab tau txais ib qho cuab yeej ua ke ntawm electrolysis rov qab thiab tshem tawm cyanide; Nickel plating cov dej khib nyiab txais cov khoom siv rov qab osmosis, thiab cov dej ntshiab npaj siv cov khoom siv ion txauv; Cov txheej txheem ion txauv resin muaj qhov cuam tshuam tsis zoo rau cov dej khib nyiab sib xyaw ua ke [1], thiab R / O yog qhov tsim nyog rau cov ntug dej hiav txwv thiab cov dej khib nyiab sib sib zog nqus. Nws cov dej concentrated thiab membrane ntxuav cov dej yuav tsum tau kho siv lub cev thiab tshuaj txoj kev kom ua tiav cov qauv tso tawm. Kev kho cov nyhuv ntawm electrocoagulation ntawm cov dej khib nyiab tsawg tshaj li cov qauv tsis zoo thiab siab [2], thiab ntau txoj hauv kev yuav tsum tau ua ke kom ua tau zoo. Los ntawm kev xav txog kev siv hluav taws xob thiab kev lag luam, kev siv tshuaj lom neeg yog ib txoj hauv kev txhim khu kev qha thiab siv tau zoo, ntau ntawm electroplating dej khib nyiab los ntawm cov teb chaws tsim, suav nrog cov teb chaws Europe thiab Amelikas, kuj raug kho nrog cov txheej txheem tshuaj, uas tau raug pov thawj ua tau los ntawm ntau xyoo ntawm kev xyaum ob qho tib si. domestically thiab thoob ntiaj teb. Qhov tseeb, vim muaj qhov sib txawv loj ntawm ntau yam thiab qhov sib txawv loj ntawm cov yam ntxwv ntawm cov txheej txheem electroplating, yuav tsis muaj tus qauv txheej txheem rau txhua qhov kev kho dej khib nyiab electroplating. Kev sib xyaw ua ke tsim nyog yuav tsum raug xaiv raws li cov dej zoo thiab cov yam ntxwv ntawm cov dej khib nyiab sib txawv, thiab qee zaum nws tseem yuav tsum tau muab faib ua ntau yam kev kho mob raws li qhov xwm txheej ntawm cov dej khib nyiab. Tshwj xeeb tshaj yog tam sim no, nws tau tawm tswv yim rau cov chaw tsim hluav taws xob electroplating kom nkag mus rau hauv cov chaw ua haujlwm hauv cov chaw ua haujlwm electroplating thiab kho cov dej khib nyiab hauv lub hauv paus. Yog tias qhov xwm txheej ntawm qhov chaw muaj kuab paug (electroplating dej khib nyiab nrog qhov zoo sib txawv) tsis tuaj yeem paub meej qhov txawv ntawm qhov chaw, qhov muaj peev xwm hloov pauv yuav tsum raug coj mus rau hauv tus account hauv kev tsim kho dej khib nyiab engineering, thiab qhov cuam tshuam ntawm kev thauj khoom yuav tsum tau txiav txim siab tag nrho. Daim ntawv ntawm electroplating concentrated cheeb tsam yuav ua rau lub txim ntawm centralized kev kho mob los ua centralized pa phem.
