Lub tsheb ciav hlau kho mob uas tsis tuaj yeem tawg 3 NTU.Cov nroj tsuag cov kws ua haujlwm tau ua ib qho kev hloov pauv rau lawv cov raj xa dej inclined - ntxiv cov kab rov tav ntws rectification seem nyob tsuas yog 1/3 ntawm lub tank ntev - thiab saib cov dej turbidity poob los ntawm 6.15 NTU rauhauv qab 2 NTU hauv 72 teev tom qab pib. Peb xyoos tom qab, qhov system tseem xa tuaj1.3 NTU nruab nrabnrog xoom hloov kho rau lub plhaub tank. Yog tias koj tab tom khiav lub tshuab raj inclined uas ua haujlwm tsis zoo hauv cov dej txias lossis tawm tsam nrog kev poob siab, qhov kev tshawb fawb no qhia tau hais tias qhov kho tau zoo li cas - thiab vim li cas nws yooj yim dua li qhov koj xav.
Kev Sib Tw: Cov Qauv Tshiab, Cov Nroj Tsuag Laus, Dej Txias
Thaum Tsawg dua los yog sib npaug rau 1 NTU Yog Txoj Cai, thiab Koj Cov Nroj Tsuag Ua Rau Tsawg dua lossis sib npaug rau 3 NTU
Lub nroog dej ua haujlwm nyob rau sab qaum teb Shaanxi, thaj chaw uas lub caij ntuj no dej kub ib txwm poob mus rau0-5 degreethiab dej turbidity swings ntawm 15 thiab 77 NTU nyob ntawm lub caij. Cov nroj tsuag tau commissioned nyob rau hauv 1989 nrog ib tug pa txheej txheem: folded - phaj flocculation, inclined tube sedimentation, thiab lub ntiajteb txawj nqus valveless lim. Ob lub tsheb ciav hlau sib npaug, txhua qhov ntsuas ntawm 6,000 m³ / d, rau tag nrho lub peev xwm ntawm 12,000 m³ / d. Rau ob xyoo lawm, qhov no yog txaus. Cov dej tiav zaum nyob ib ncig ntawm 3 NTU - tau raws li tus qauv qub.
Ces cov kev cai hloov. Cov qauv kev huv dej tshiab tau tsa lub bar los ntawm Tsawg dua lossis sib npaug rau 3 NTU rauTsawg dua lossis sib npaug rau 1 NTU. Cov txheej txheem uas twb muaj lawm tsis tuaj yeem kaw qhov sib txawv. Cov dej ua haujlwm tau ntsib qhov kev txiav txim siab txhua tsob ntoo laus thaum kawg ntsib:demolish thiab rebuild, los yog retrofit nyob rau hauv lub hneev taw uas twb muaj lawm. Qhov kawg yog qhov kev xaiv tiag tiag xwb. Cov qauv kev kho mob tau nyob hauv tsev rau kev rwb thaiv tsev thermal - qhov tsim nyog nyob rau sab qaum teb Shaanxi kev nyab xeeb, qhov chaw tso tsheb hlau luam sab nraum zoov yuav khov. Tuav cov phab ntsa kom nthuav dav tsis yog ntawm lub rooj. Lawv yuav tsum ua kom lawv ua tau zoo dua.
Lub hom phiaj: nce ib qho - tsheb ciav hlau muaj peev xwm ntawm 6,000 m³ / d mus rau10,000 m³/d(tag nrho cov khoom tsim tawm: 16,000 m³ / d), nrog dej turbidity tsis tu ncua qis dua 3 NTU kom muab cov lim dej sib ntaus sib tua ntawm tsawg dua lossis sib npaug rau 1 NTU tiav- dej yuav tsum tau ua.
Lub tswv yim Retrofit: Peb Kev Txhim Kho, Ib Txoj Cai
Pab pawg engineering tsis tau kov lub plhaub tank. Lawv hloov cov txheej txheem hauv nws, hloov cov qub "folded-plate flocculation + inclined tube sedimentation + gravity valveless filter" rau hauv"hu rau flocculation + txhim kho inclined tube settler + gravity valveless lim". Peb qhov kev hloov kho tshiab tau tsav qhov kev hloov pauv:
1. Multi-Tube Tov Khoom Hloov Tubular Static Tov Khoom
Tus thawj tubular static tov khoom ua ib yam: nws tov. Kev hloov ntau- tube tov khoom ua peb yam ib txhij:txiav thiab splitting ntws, rov qab reflux, thiab sib tov ceev. Thaum dej dhau los ntawm ntau- raj geometry, siab - zaus eddy tam sim no tsim ntawm cov yeeb nkab phab ntsa ciam txheej. Cov eddies no tsim micro- thaj tsam ntawm qhov hnyav shear uas faib cov coagulant sib npaug ntawm tag nrho cov ntws hla -section hauv vib nas this. Qhov ntsuas sib tov efficiency tshaj94%, thiab lub taub hau poob qis dua qhov qub static mixer - ib qho kev sib txawv txawv uas txhais tau tias zoo dua sib xyaw nrog tsawg zog.
Cov txiaj ntsig zoo:20-30% tshuaj txuagpiv rau tus thawj tov khoom, nrog zoo adaptability rau ntws tus nqi thiab dej zoo variations. Rau cov nroj tsuag uas pom cov dej turbidity viav vias ntawm 15 mus rau 77 NTU raws caij nyoog, qhov kev hloov pauv tseem ceeb.
2. Daim phiaj Flocculation nrog Lub Hnub Qub-Shoed Vanes Hloov Folded-Plate Flocculation
Folded -phaj flocculation ua haujlwm los ntawm kev yuam dej los ntawm txoj kev serpentine ntawm cov phaj sib npaug. Nws tsim turbulence, tab sis tsis yog qhov zoo. Kev txhim kho tsim sivlub hnub qub - zoo li lub vanesmounted perpendicular mus rau cov kev taw qhia ntws nyob rau hauv daim phiaj compartments. Cov vanes no ua kom muaj siab -frequency micro-vortexes - turbulence ntawm qhov ntsuas uas txhawb kev sib tsoo particle yam tsis muaj kev sib cais flocs uas twb tsim lawm.
Lub flocculation tank muab faib ua11 kabhla ob theem tshuaj tiv thaiv. Theem 1: 8 compartments ntawm 1.5 m × 1.5 m txhua, 8.95-feeb tuav. Theem 2: 3 qhov chaw ntawm 1.5 m × 2.0 m txhua, 4.48-feeb tuav. Tag nrho lub sijhawm hydraulic tuav:13.43 Nwsntawm GT tus nqi ntawm 1.7 × 10⁴. Qhov ob -theem tsim tsim denser, ntau shear-resistant flocs tshaj ib zaug -stage flocculation - ib qho tseem ceeb kom zoo dua thaum cov flocs tom qab nkag mus rau hauv tube settler cheeb tsam, qhov twg ntau turbulence yuav tawg lawv sib nrug.
3. Qhov Tseem Ceeb Innovation: Kab rov tav Flow Rectification Section nyob rau hauv pem hauv ntej ntawm lub raj Settler
Qhov no yog qhov uas qhov retrofit tawm ntawm tus qauv kev coj ua, thiab qhov twg qhov kev ua tau zoo tshaj plaws tau ua tiav. Ib qho tshuaj inclined tube settler tau txais dej ncaj qha los ntawm flocculation tank qhov hluav taws xob. Kev hloov pauv sai sai: dej mus los ntawm qhov tsis sib haum xeeb, sib xyaw ua ke - ntws tswj mus rau hauv cov txheej txheem laminar tsis muaj qhov nruab nrab. Qhov tshwm sim yogkev faib tsis sib npaugnyob rau hauv lub cev pob. Qee cov channel pom cov nrawm nrawm thiab ntws flocs ncaj qha mus. Lwm tus pom qhov nrawm nrawm thiab khaws cov sludge. Ob qho xwm txheej degrade effluent zoo.
Lub retrofit ntxiv ob lub ntsiab lus uas daws qhov no:
Ib tug submerged weir ntawm lub flocculation tank qhov hluav taws xob.Es tsis txhob cov dej pov tseg ncaj qha mus rau hauv thaj chaw faib khoom, nws thawj zaug ntws hla lub qhov dej hauv dej uas ua raws li cov dej rectifier - smoothing tawm tshaj tawm gradients thiab dissipating loj -scale turbulence ua ntej cov dej nkag mus rau hauv lub settler.
Kab rov tav ntws seem occupying 1/3 ntawm tag nrho cov tank ntev (24 m²).Qhov no yog qhov innovation. Tom qab hla lub weir, dej nkag mus rau kab rov tav - ntws ua ntej nce los ntawm cov raj inclined. Qhia phab ntsa nyob rau hauv ob qho tib si kab rov tav seem thiab inclined raj seem tswj txoj kev khiav. Lub cheeb tsam kab rov tav ua haujlwm peb zaug ib txhij: nws txo cov kab rov tav ntws mus rau12.73 hli / s(nyob rau hauv 10-18 mm / s qhov rais uas kev tshawb fawb qhia tau hais tias yog ib qho tseem ceeb rau kev ruaj khov sedimentation), nws muab lub sij hawm ntxiv rau cov flocs loj, thiab nws ua raws li ib tug hydraulic buffer uas absorbs ntws fluctuations ua ntej lawv mus txog lub raj nras.
Cov phab ntsa faib rau qhov kawg ntawm qhov kev hloov pauv sivperforations nrog dav dav ntawm sab saum toj thiab nqaim qhov sib nrug hauv qab. Cov txee no- qhov kev npaj tsis txaus ntseeg yog txhob txwm tshaj tawm: nws them nyiaj rau lub ntuj nyiam ntawm cov dej kom luv luv - Circuit Court mus rau sab saum toj ntawm thaj chaw faib khoom, yuam kom muaj qhov sib txawv ntsug ntws ntau dua thoob plaws qhov siab ntawm lub raj ntim.
Vim li cas Kab Kab Ntsig Flow Seem Ua Haujlwm: Cov Txheej Txheem Engineering
Qhov teeb meem nrog cov tsoos inclined tube settlers tsis yog cov hlab lawv tus kheej. Nws yog dab tsi tshwm simua ntej dej mus txog lawv. Kev tshawb fawb tau txheeb xyuas plaub qhov kev txwv uas tswj hwm qhov sib txawv ntawm qhov sib txawv ntawm cov tube: lub tank ntev - txog - dav piv (L / B), qhov chaw thauj khoom ntawm qhov chaw (q), txoj kab uas hla (D), thiab qhov siab ntawm thaj chaw faib khoom hauv qab cov raj.
Ntawm no,L / B piv thiab qhov chaw thau khoom (q) muaj qhov cuam tshuam loj tshaj plaws. Raws li qhov sib piv L / B nce, kev faib tawm ntau dua tsis yog -ib puag ncig, thiab qhov tseem ceeb tshaj tawm tshaj tawm - qhov nrawm tshaj plaws uas ib feem ntawm ib qho me me nyob ntawm - nce. Qhov chaw thau khoom (q) yog qhov sib piv rau qhov tseem ceeb ntawm qhov nrawm nrawm: thawb ntau ntws los ntawm tib cheeb tsam, thiab koj xav tau qhov kev sib tw siab dua los ntes tib cov khoom. Ob qhov teebmeem ua haujlwm tawm tsam cov dej tsis zoo.
Cov neeg nyob hauv lub raj qub kuj raug kev txom nyem los ntawm perforated - teeb meem phab ntsa. Txhawm rau kom ua tiav kev faib tawm, cov phab ntsa perforated ntawm qhov nkag xav tau qhov qhib me dua li kab rov tav - ntws cov dej ntws tawm - uas txhais tau tiassiab dua orifice velocities. Siab - dav hlau tshaj tawm los ntawm cov orifices no tawg flocs uas lub tank flocculation tsuas yog siv sijhawm 13 feeb. Qhov phem tshaj, cov dav hlau tuaj yeem ua rau cov sludge tuag tso rau hauv qab ntawm thaj chaw faib khoom, rov- tshem tawm cov khib nyiab uas twb tau nyob.
Txoj kab rov tav ntws los daws cov kab teeb meem no ntawm nws cov hauv paus hniav. Los ntawm kev ntxiv 1/3 ntawm lub tank ntev raws li kab rov tav - ntws cheeb tsam ua ntej cov hlab inclined, tus tsim ua tiav plaub yam:
| # | Nws Ua Dab Tsi | Nws ua haujlwm li cas |
| 1 | Tswj cov kab rov tav ntws nrawm | Kab rov tav ntu coj qhov pib kab rov tav tshaj tawm mus rau 12.73 mm / s - zoo nyob rau hauv lub qhov rais 10–18 mm / s qhov twg effluent zoo nyob ruaj khov tsis hais txog ntawm qhov chaw thauj khoom thiab sludge qhov tob fluctuations. Hauv qab 10 mm / s, koj nyob nraum nkim tank ntim. Tshaj 18 mm / s, floc breakage ua qhov tseem ceeb. |
| 2 | Absorbs shock loads | 24 m² kab rov tav cheeb tsam ua raws li hydraulic capacitor. Thaum cov dej nyoos turbidity spikes thaum lub caij dej nyab, cov kab rov tav buffers cov surges, muab flocs ntxiv settling sij hawm ua ntej lawv mus txog inclined hlab. Ib txwm tube settlers tsis muaj xws li buffer - ib tug ntws surge hits lub raj nras ncaj qha. |
| 3 | Txo nce siab tshaj tawm hauv cov hlab ntsha | Los ntawm ua ntej -tso loj flocs nyob rau hauv cheeb tsam kab rov tav, tshem tawm cov khib nyiab concentration nkag mus rau hauv cov hlab inclined yog qis dua, tso cai rau ib tug qis upward flow velocity (2.79 mm / s nyob rau hauv no tsim). Tsawg tshaj tawm txhais tau hais tias muaj kev kub ntxhov tsawg, uas txhais tau tias zoo dua floc capture. Lub raj- sab hauv tshaj tawm yog 3.5 mm / s nrog rau 4.76-feeb nyob hauv lub sijhawm - laminar thoob plaws. |
| 4 | Blocks qis-flocs flocs los ntawm kev nkag mus rau hauv cov raj | Qhia cov phab ntsa hauv ob ntu tsim ib txoj hauv kev uas tsuas yog denser, zoo - tsim flocs nkag mus rau hauv lub raj. Tsawg- ntom ntom flocs - hom uas yuav sib cais thiab nqa los ntawm cov hlab ntsha li turbidity - nyob rau hauv seem kab rov tav thiab nyob ntawd. Qhov no yog qhov tshwj xeeb tshaj yog rau qis-kub, qis-turbidity, thiab siab-algae dej, qhov twg flocs inherently tsis muaj zog. |
