Lub hauv paus ntsiab lus ua haujlwm ntawm cov dej khib nyiab integrated tshuab

1: Electrolysis: Daim ntawv thov ntawm cov txheej txheem ntawm electrolysis, kom cov khoom tsis zoo hauv cov dej khib nyiab qub los ntawm cov txheej txheem electrolytic ntawm Yang thiab Yin ncej raws li oxidation thiab txo cov tshuaj tiv thaiv hloov mus rau hauv insoluble hauv dej precipitate, txhawm rau cais thiab tshem tawm. yam phem. Feem ntau yog siv los kho cov dej khib nyiab uas muaj chromium thiab cyanide-muaj cov dej khib nyiab, tab sis kuj siv los tshem tawm cov hlau hnyav ions, roj thiab cov khib nyiab pov tseg hauv cov dej khib nyiab; Nws kuj tseem tuaj yeem ua kom txias thiab adsorb cov dye molecules nyob rau hauv lub xeev colloidal los yog yaj lub xeev nyob rau hauv cov dej khib nyiab, thiab REDOX kev txiav txim tuaj yeem rhuav tshem cov xim pawg thiab ua tiav cov nyhuv decolorization.2: Kev sib tov: Cov khoom siv insoluble hauv dej tom qab electrolysis yog thawj zaug precipitated. nyob rau hauv no link.3: PAC dosing: uas yog, polyaluminum chloride, ib tug tshiab inorganic polymer coagulant, uas muaj ib tug high degree ntawm hluav taws xob neutralization thiab bridging nyhuv ntawm colloids thiab hais nyob rau hauv dej, thiab muaj peev xwm tshem tawm micro-toxic tshuaj thiab hnyav hlau. ions.4: PAM dosing: uas yog, polyacrylamide, muaj zoo flocculation, tuaj yeem txo qhov kev sib txhuam ntawm cov kua. Kev siv ua ke ntawm PAC thiab PAM yog ua kom PAC ua kom tiav qhov nruab nrab ntawm kev them nqi / colloid instability los tsim ib qho me me floc, thiab ntxiv rau qhov floc ntim yog tsim nyog rau tag nrho cov nag lossis daus.5: Scraping slag: Lub kaw lus roj yaj ua kom muaj coob tus. ntawm cov npuas zoo nyob rau hauv dej, kom cov huab cua txuas mus rau insoluble floc tom qab ntxiv tshuaj flocculation nyob rau hauv daim ntawv ntawm heev dispersed me npuas npuas, uas ua rau lub xeev ntawm ntom tsawg tshaj li dej, siv lub hauv paus ntsiab lus ntawm buoyancy mus ntab rau hauv dej. nto, thiaj li ua tiav cov kua dej sib cais, thiab tom qab ntawd muab cov khoom pov tseg los ntawm cov scraper mus rau lub tank slag, thiab thaum kawg ntws mus rau lub tank sludge.6: Multi-media filtration txheej: ① Quartz xuab zeb pom yog lim dej nrog siab turbidity los ntawm ib tug tej thickness ntawm granular los yog non-granular quartz xuab zeb, zoo cuab thiab tshem tawm cov teeb meem, organic teeb meem, colloid hais, microorganisms, chlorine, tsw thiab ib co hnyav hlau ions nyob rau hauv dej; Cov lim dej ua kom cov pa roj carbon activated yog cov txheej txheem ntawm kev cuam tshuam cov pa phem nyob rau hauv lub xeev tshem tawm ntawm cov dej, thiab cov teeb meem raug tshem tawm yog ntim nrog qhov sib txawv ntawm cov activated carbon.7. Lub pas dej ntshiab: Vim tias cov dej ntws me me tom qab txheej txheej lim dej ntau, SS index ntawm cov dej lim tau zoo heev, thiab nws yuav tsum tau khaws cia ib ntus hauv qhov txuas no.

8: Membrane filtration system: muab faib ua ob theem, uas yog hollow fiber ntau thiab RO rov qab osmosis membrane, kev siv lub twj tso kua mis siab ua lub zog tsav los cuam tshuam ntau yam inorganic ions, colloidal tshuaj thiab macromolecular solutes hauv dej, thiaj li yuav tau txais net dej standard tso tawm. Nyob rau tib lub sijhawm, rov qab osmosis concentrated dej rov qab mus rau lub tank electrolytic rau kev kho dua tshiab.
