Kev txhim kho ntawm Electroplating Wastewater Treatment Technology
Hauv Suav teb, kev kho cov dej khib nyiab electroplating tsim nyob rau hauv cov txheej txheem ntawm electroplating ua yog nyob rau hauv thawj theem ntawm txoj kev loj hlob. Hauv cov nroog loj tsim, muaj ntau thiab cov nroj tsuag tawg tawg, tsis tsim nyog layout ntawm cov nroj tsuag electroplating, thiab rov qab electroplating ntau lawm thiab kev siv tshuab. Nws raug txwv rau ob hom chromium thiab cyanide, thiab theem ntawm kev kho dej khib nyiab yog qhov tsawg heev. Nrog rau kev hloov kho txuas ntxiv ntawm electroplating ua thiab cov thev naus laus zis ntau lawm thiab kev txhim kho txuas ntxiv thiab kev nce qib ntawm kev kho dej khib nyiab science thiab thev naus laus zis, txij li kev hloov kho thiab qhib rau xyoo 1980, hom electroplating rau kev kho dej khib nyiab tau nce, thiab txoj kev kho electroplating kuj tseem muaj. tsim los ntawm ib qho kev kho mob ib leeg mus rau kev kho mob dav dav. Txoj kev loj hlob ntawm electroplating wastewater kho rau socialization, equipmentization thiab serialization tau nce los ua kev pom zoo thiab kev coj ntawm tib neeg txoj kev siv zog. Txawm li cas los xij, vim muaj ntau yam, Tuam Tshoj tseem ua raws li lub hauv paus ntsiab lus ntawm leej twg qias neeg, leej twg tswj nws, thiab tseem muaj qee qhov sib txawv piv nrog rau ntau hom kev sib raug zoo thiab kev tswj hwm tshwj xeeb hauv qee lub teb chaws tsim kev lag luam hauv ntiaj teb.
Fieldbus Distributed Control System rau Electroplating Hluav taws xob cua sov yeeb nkab
Txhawm rau txhim kho kev lag luam kev ntseeg siab ntawm kev saib xyuas thiab txhim kho kev tswj hwm kev tshawb fawb
Electroplating hluav taws xob cua sov yeeb nkab dej khib nyiab kho chav tsev
Cov dej khib nyiab, cov dej khib nyiab alkaline, cov dej khib nyiab sib xyaw thiab cov dej khib nyiab uas muaj chrome uas tau tsim nyob rau hauv cov txheej txheem rov tsim dua tshiab tau sau rau hauv lawv cov tso tsheb hlau luam, thiab cov kua rov ua dua tshiab tau sau rau hauv lawv cov dej khib nyiab. Cov dej khib nyiab no muaj ntau cov hlau ions thiab Acid, alkali, thiab lwm yam, yog li ntau yam dej khib nyiab (kua) yuav tsum tau kho. Chav tsev kho dej khib nyiab suav nrog kev kho tshuaj lom neeg thiab ib feem "polishing". Lub hom phiaj ntawm kev kho tshuaj yog ntxiv oxidants, flocculants, txo cov neeg ua haujlwm, acids thiab alkalis rau cov dej khib nyiab kom tiav cov txheej txheem xws li tshem tawm Cr6 ntxiv, kho pH, thiab nag lossis daus ntawm cov hlau ions. Cov seem "polishing" siv ib qho kev xaiv ion txauv kem kom tshem tawm cov hlau ions ntxiv los ntawm cov dej thiab coj cov dej tawm mus rau cov qauv tawm los ntawm kev ua kom tsis zoo thiab kev tswj pH kawg.
