Lub Dissolved Air Flotation (DAF) system yog ib qho kev nqis peev tseem ceeb rau txhua qhov chaw ua lag luam. Txawm li cas los xij, ntau tus neeg saib xyuas cov nroj tsuag thiab cov neeg ua haujlwm pom tias dhau sijhawm, lawv qhov kev ua tau zoo pib poob. Tej zaum koj yuav pom muaj huab cua effluent, sludge uas nqa dej ntau dhau, los yog ib qho kev npaj txhij txog ntawm lub zog thiab cov nqi tshuaj.
Qhov tseeb yog, kev ua tiav qhov kev ua tau zoo tshaj plaws yuav tsum muaj ntau dua li kev txhim kho cov khoom siv xwb. Nws xav tau kev sib xyaw ua ke ntawm qib siab - kho vajtse zoo thiab ntse, kev saib xyuas zoo. Txhawm rau pab koj tau txais txiaj ntsig zoo tshaj plaws ntawm koj cov peev txheej kho dej khib nyiab, ntawm no yog 5 lub tswv yim tseem ceeb los txhim kho koj qhov kev ua tau zoo DAF.
1. Tus Tswv Koj Tus Kheej Zoo & Kev Ua Ntej
Qhov kev ua tau zoo ntawm koj DAF pib ntev ua ntej cov dej khib nyiab nkag mus rau hauv lub tank flotation. Yog tias tus neeg muaj peev xwm tswj tsis tau zoo, txawm tias qhov zoo tshaj plaws DAF system yuav tawm tsam.
* Kev tshuaj ntsuam tsis yog- sib tham tau: xyuas kom meej tias cov ntxaij vab tshaus zoo lossis cov sieves nyob hauv qhov chaw thiab ua haujlwm kom raug. Cov khib nyiab loj, fibers, lossis cov khoom noj khoom haus tuaj yeem yooj yim txhaws cov micro- npuas tso tawm nozzles, ua kom lub cev ua haujlwm tau zoo.
* Teeb meem sib npaug: Sudden spikes nyob rau hauv tus nqi txaus los yog cov pa paug concentration (shock loads) tuaj yeem cuam tshuam lub kaw lus. Ib lub tank sib npaug pab ua kom cov kev hloov pauv no, muab cov dej khov kho thiab tswj tau mus rau DAF.
2. Precision Chemical Dosing
Tshuaj pretreatment feem ntau yog cov caj qaum ntawm txoj kev ua tiav DAF, tab sis "ntau" tsis yog ib txwm "zoo dua."
* Ua qhov ntsuas lub thawv tsis tu ncua: Cov dej khib nyiab hloov pauv. Kev ntsuas lub thawv tsis tu ncua yuav pab koj txiav txim siab qhov zoo tshaj plaws thiab ntau npaum li cas ntawm coagulants (xws li PAC) thiab flocculants (xws li PAM).
* Tsis txhob noj ntau tshaj -: Kev siv tshuaj ntau dhau tsis tsuas yog ua rau koj cov peev nyiaj ua haujlwm tab sis kuj ua rau cov sludge ntim thiab tuaj yeem ua rau cov floc tsis ruaj, ua rau kev sib cais nyuaj. Lub hom phiaj yog los tsim kom muaj zog, buoyant flocs nrog qhov tsawg kawg nkaus koob tshuaj.
3. Muab qhov tseem ceeb rau Micro-Bubble Quality
Lub plawv ntawm ib qho DAF system yog nws lub peev xwm los tsim ntau lab ntawm cov npuas microscopic (feem ntau 10-30 microns). Cov npuas no yog cov tsheb uas nqa cov pa phem rau saum npoo.
* Tshawb xyuas qhov kev tso tawm: Qhov ua tau zoo ntawm cov npuas tiam yog nyob ntawm qhov xwm txheej ntawm cov cua tso tawm nozzles lossis saturator. Tsis tu ncua xyuas cov clogs los yog hnav thiab tsim kua muag.
* Tswj lub siab kom zoo: xyuas kom lub twj tso kua mis rov ua dua thiab lub tshuab cua compressor ua haujlwm ntawm lub siab tsim (feem ntau 4-6 bar). Cov kev tswj tsis zoo ua rau muaj cov npuas loj dua, tsis muaj zog uas tsis tuaj yeem nqa cov khib nyiab zoo.
4. Optimize Hydraulic thiab Flow Distribution
Txawm tias muaj cov npuas zoo meej thiab tshuaj lom neeg, kev tsim hydraulic tsis zoo tuaj yeem rhuav tshem kev sib cais.
* Tshem tawm luv luv -circuiting: Dej yuav tsum ntws sib npaug thoob plaws lub tank. Xyuas kom pom tias qhov nkag thiab qhov hluav taws xob baffles tsis zoo thiab raug tso cai los tiv thaiv "luv-circuiting," qhov twg dej hla qhov chaw sib cais.
* Tswj lub sij hawm tuav: Xyuas kom lub sij hawm tuav hydraulic (HRT) txaus rau kev sib cais tab sis tsis ntev npaum li ntawd nws thiaj li txo tau. Kho tus nqi ntws kom haum rau DAF lub peev xwm tsim yog qhov tseem ceeb rau kev ruaj ntseg.
5. Leverage Automation rau Sludge Tshem Tawm
Dab tsi tshwm sim ntawm qhov chaw ntawm lub tank yog qhov tseem ceeb raws li qhov tshwm sim hauv qab no. Yog tias floated sludge (scum) tsis raug tshem tawm sai thiab tsis tu ncua, nws tuaj yeem sib cais thiab dab dej, ua rau muaj kuab paug thib ob.
* Automate cov txheej txheem skimming: Niaj hnub nimno DAFs tuaj nrog automated skimmers thiab kua theem tswj. Xyuas kom cov no yog calibrated kom raug thiaj li hais tias sludge raug tshem tawm tsis tu ncua los yog ntawm optimized ncua sij hawm.
Ntse tswj vaj huam sib luag: Siv PLC-raws li kev tswj cov tshuab uas tuaj yeem hloov kho cov sludge tawm lub voj voog thiab rov ua dua qhov sib piv raws li qhov tiag - lub sijhawm. Qhov no txo qis kev ua haujlwm ntawm tes thiab ua kom muaj kev ua haujlwm zoo ib yam.
Qhov sib npaug rau kev vam meej: Cov cuab yeej zoo + Kev ua haujlwm ntse
Kev ua kom zoo rau DAF tsis yog ib qho haujlwm - sijhawm; nws yog kev cog lus tsis tu ncua rau kev ua haujlwm zoo. Los ntawm kev tsom mus rau tsib qhov chaw no -pretreatment, tshuaj siv tshuaj, npuas zoo, hydraulics, thiab automation-koj tuaj yeem ua kom koj lub cev khiav lag luam ntseeg siab, ua raws li cov kev cai tawm, thiab ua rau cov nqi ua haujlwm qis.
Puas yog koj qhov DAF tam sim no ua haujlwm tsis zoo lossis ua rau koj raug nqi ntau dhau los khiav?
Qee zaum, ob peb lub tswv yim hloov kho dua tshiab lossis kev ua haujlwm tshaj lij- tuaj yeem ua rau txhua qhov sib txawv. Hu rau peb cov kws paub txog dej khib nyiab hnub no kom paub meej txog kev kuaj mob. Peb tuaj yeem pab koj txheeb xyuas cov kev tsis sib haum xeeb, txhim kho koj qhov kev teeb tsa tam sim no, lossis pom zoo kom hloov kho qhov seem kom coj koj DAF rov qab mus rau qhov ua tau zoo tshaj plaws.
