Koj tuaj yeem tsim lub raj xa dej uas zoo li ntawm daim ntawv -thiab tseem ua haujlwm tsis tiav

Inclined tube settlers tau nyob ib ncig ntawm 50 xyoo. Tuam Tshoj tau tsim nws thawj zaug nce siab- chav dej ntws hauv xyoo 1972, thiab los ntawm 1975 cov thev naus laus zis tau tsim qauv. Niaj hnub no, tube settlers yog siv nyob rau hauv lub nroog cov nroj tsuag, dej khib nyiab thib ob clarifiers, muaj dej purification, thiab txawm steel zeb effluent kev kho mob. Lub hauv paus ntsiab lus yog elegant: laminar ntws los ntawm inclined raws tsub kom qhov chaw daws teeb meem zoo los ntawm ib qho ntawm 5-10, dramatically shrinking tank ntim.

Tab sis ntawm no yog dab tsi cov phau ntawv feem ntau hla:feem ntau tube settler tsis ua hauj lwm tsis yog los ntawm lub raj modules lawv tus kheej. Lawv tshwm sim los ntawm cov ntsiab lus nyob ib puag ncig lawv.Kev hloov pauv inlet. Lub sludge hopper angle. Hydraulic gradient los ntawm flocculation tank. Tau txais cov no tsis raug, thiab koj yuav muaj huab cua nkag los rhuav tshem koj qhov chaw nyob, floc nqa mus rau hauv koj cov dej phwj tuaj, lossis cov sludge accumulating nyob rau hauv qhov chaw tuag kom txog thaum nws mus rau hauv dej phwj tuaj.

Kab lus no yog ib daim teb -qib qhia txog kev tsim cov ntsiab lus thiab kev ua haujlwm ua haujlwm uas cais lub raj xa hluav taws xob uas khiav teeb meem- pub dawb rau xyoo los ntawm ib qho uas ua rau mob taub hau. Yog tias koj tab tom tsim ib qho kev teeb tsa tshiab, rov kho lub tank uas twb muaj lawm, lossis teeb meem kev ua haujlwm tsis zoo, cov no yog cov ntsiab lus tseem ceeb.

Yog tias koj xav tau tube settler media specifications thaum nyeem ntawv,Juntai manufactures PP thiab PVC tube settler modulesnyob rau hauv ntau qhov ntau thiab tsawg channel thiab daim ntawv thicknesses rau ob qho tib si dej thiab dej khib nyiab.

Tsib cov ntsiab lus tsim uas feem ntau engineers tau yuam kev

2.1 Flow Velocity los ntawm Reaction Tank: Tsis txhob txiav cov kaum ntawm no

Qee tus neeg tsim qauv thawb lub nrawm nrawm los ntawm cov tshuaj tiv thaiv tank mus rau lub raj xa dej mus rau0.5–0.6 m/s, sim txo cov yeeb nkab txoj kab uas hla thiab txuag ntawm pej xeem cov nqi. Qhov no yog ib qho yuam kev. Ntawm qhov nrawm, cov flocs uas tsim kom zoo nyob rau hauv cov tshuaj tiv thaiv tank tau txaissheared sib nrugua ntej lawv puas tau mus txog qhov chaw nyob. Koj xaus nrog micro-flocs uas lub raj xa dej tsis tuaj yeem ntes tau zoo- thiab turbidity hauv koj cov dej ntws uas yuav tsum tsis txhob muaj.

Qhov tseeb tsim tshaj tawm yog 0.20-0.25 m / s siab tshaj plaws.Yog lawm, qhov no txhais tau tias loj dua - txoj kab uas hla inlet kav lossis cov channel. Yog, nws raug nqi ntau dua ua ntej. Tab sis lwm txoj hauv kev yog qhov chaw nyob uas tsis tau ncav cuag nws qhov kev tsim qauv vim tias cov flocs nkag mus rau nws twb puas lawm.

2.2 Inlet Tsim: Ib phab ntsa perforated yog qhov yuam kev

Ntau tus neeg tsim qauv luam tawm kab rov tav - ntws sedimentation tank mus kom ze thiab siv aperforated phab ntsanyob rau hauv lub inlet mus rau lub cev settler. Qhov no yog ib qho kev nkag siab yuam kev ntawm cov tube settlers ua haujlwm li cas.

Hauv kab rov tav - ntws tank, phab ntsa perforated pab faib cov dej sib npaug thoob plaws lub tank dav. Dej ntwsdhauphab ntsa rau hauv thaj chaw nyob. Nyob rau hauv ib lub tube settler, dej nkag los ntawmhauv qab nolub raj module thiab ntwsnce tojlos ntawm inclined channels. Lub inlet flow direction yog txawv kiag li.

Ib phab ntsa perforated ntawm lub raj xaum inlet tsimturbulence thiab tuag aaves tsis yog ib qho kev faib tawm. Txoj kev kom raug yog ib qhoqhib kev hloov pauv channeluas tso cai rau cov dej nkag mus rau thaj chaw faib khoom hauv qab cov raj sib npaug, nrog rau kev khiav -txoj kev ncaj nraim yog tias xav tau. Lub hom phiaj yog los nthuav qhia cov txheej txheem nrawm nrawm mus rau hauv qab ntawm lub raj module- ib yam dab tsi ntawm phab ntsa perforated ua haujlwm tawm tsam hauv qhov kev teeb tsa upflow.

2.3 Hydraulic Gradient: Khaws cov qib dej sib npaug

Qhov no yog ib qho ntawm cov ntsiab lus uas suab tsis tseem ceeb tab sis ua rau muaj teeb meem tiag tiag. Cov dej theem nkag mus rau thaj chaw hloov pauv los ntawm cov tshuaj tiv thaiv tank yuav tsum, theoretically, zaumsaum toj nocov dej effluent theem los ntawm tus nqi ntawm lub taub hau poob los ntawm lub raj module. Hauv kev xyaum, qhov sib txawv ntawm lub taub hau me me - feem ntau yog ob peb centimeters.

Yog hais tias cov dej muaj txiaj ntsig yog qhov siab dua li cov dej ntws tawm, cov cua nkag tau tshwm sim.Cov dej cascading los ntawm qhov siab dua mus rau hauv lub raj xa dej ntxiab cua npuas uas nce los ntawm cov raj xa dej, cuam tshuam cov laminar ntws profile thiab nqa flocs mus rau saum npoo. Cov txiaj ntsig zoo li floc floatation-tab sis nws tsis muaj dab tsi cuam tshuam nrog chemistry. Nws yog purely hydraulic.

Txoj cai tsim:khaws cov dej muaj zog thiab cov dej ntws tawm kom ze kom sib npaug li hydraulically ua tau. Yog tias qhov sib txawv ntawm lub taub hau tsis tuaj yeem zam tau vim qhov chaw txwv tsis pub, siv lub qhov dej nkag nrog cov baffle tseem ua rau lub zog tsis muaj cua nkag.

2.4 Zone Heights: Yam Koj Yuav Tsum Tau Txo, thiab Qhov Koj Ua Tsis Tau

Qee tus neeg tsim qauv, sim txo qis qhov tob ntawm lub tank (thiab yog li tus nqi excavation), txo qhov siab ntawm txhua cheeb tsam hauv lub raj xa dej. Qhov no yog qhov uas nkag siab txog kev ua haujlwm ntawm txhua cheeb tsam tseem ceeb. Qee qhov siab tuaj yeem txiav. Lwm tus tsis tuaj yeem-thiab txiav lawv yuav ua rau tsis zoo mus tas li.

Daim duab 1 - Cheeb tsam qhov siab specifications nyob rau hauv ib tug inclined tube settler: sludge hopper, faib cheeb tsam, raj module, thiab ntshiab dej cheeb tsam

Sludge hopper qhov siab: Tsis txhob txo.Lub hopper phab ntsa lub kaum sab xis ntawm lub tank hauv qab yuav tsum yog qhov siab txaus rau sludge rau swb- feem ntau55-60 degree. Qee tus neeg tsim qauv sim txuag qhov siab los ntawm kev txo lub kaum sab xis no, tab sis qhov tshwm sim yog sludge uas lo rau ntawm phab ntsa hopper es tsis txhob zawv zawg mus rau qhov chaw tawm. Nyob rau tib lub sij hawm, cov sludge nyob rau hauv lub hopper ces kaum mus anaerobic, tsim roj, thiab nqa flocs mus rau hauv cheeb tsam chaw. Qhov siab hopper yog txiav txim los ntawm geometry - tank dav, tus naj npawb ntawm hoppers, thiab qhov tsawg kawg nkaus swb kaum. Nws tsis yog qhov hloov pauv dawb.

Daim duab 2 - Sludge hopper geometry: phab ntsa lub kaum sab xis, qhov dav, thiab qhov siab kev sib raug zoo rau kev txhim kho sludge paug

Kev faib ua cheeb tsam (zej tsam) qhov siab: 1.0-1.3 m.Phau ntawv tsim qauv hais tias 1.3 m; cov sedimentation tank code hais tias 1.0 m. Ob leeg tuaj yeem ua haujlwm, tab sis ntawm no yog qhov kev xav txog: qhov ntiav ib qho chaw faib khoom tsimtsis sib npaug ntws nkagmus rau hauv qab ntawm lub raj module-qee lub raj tau overloaded thaum lwm tus yog underutilized. Yog tias koj qhov inlet geometry yog qhov zoo -tsim (qhib channel, ib qho mus kom ze), 1.0 m yog txaus. Yog tias qhov chaw tso cai, 1.2–1.3 m muab kev zam txim ntau dua rau qhov tsis yog - zoo tagnrho inlet tej yam kev mob.

Cov dej ntshiab huv qhov siab: 0.7-1.0 m.Qhov no yog thaj tsam saum lub raj module uas cov dej ntshiab tau sau. Qhov siab nws tus kheej tsis tshua tseem ceeb tshaj qhovuniformity ntawm effluent collection-Kev thauj khoom tsis sib xws hauv thaj chaw no tuaj yeem tsim cov dej ntws tawm hauv zos los ntawm qee cov raj xa dej uas tshaj qhov tsim kho qhov nrawm, nqa cov khib nyiab rau hauv cov dej ntws tawm. Tsom ntsoov rau weir tsim thiab theem, tsis yog qhov siab xwb.

Kev Ua Haujlwm: Dab tsi tus kws tsim qauv tsim yuav tsis qhia koj txog kev khiav cov khoom no

Kev ua haujlwm zoo tuaj yeem them nyiaj rau qhov kev tsim me me. Kev ua haujlwm tsis zoo tuaj yeem ua rau txawm tias lub raj xa hluav taws xob tsim tau zoo heev. Nov yog cov lus qhia txog kev ua haujlwm uas cov neeg ua haujlwm paub txog kev kawm- feem ntau nyuaj.

3.1 Tshuaj Dosing: Nyeem Flocs, Tsis Yog Tus Meter

Kev siv tshuaj lom neeg rau sedimentation yog ob qho tib si science thiab khoom siv tes ua. Lub thawv kuaj muab rau koj pib, tab siscov tshuaj tiv thaiv tank qhia koj txhua yam koj xav paub hauv lub sijhawm-yog tias koj paub yuav nrhiav dab tsi.

Rau kev kho dej:Feem ntau tsuas yog xav tau ib coagulant xwb -PAC (polyaluminium chloride) los yog alum ntawm 1-5% kua concentration. Thaum cov dej nyoos tsis zoo, cov zaub mov - qib coagulant tuaj yeem raug ntxiv. Kev soj ntsuam tseem ceeb: flocs hauv cov tshuaj tiv thaiv tank yuav tsum yoguniform, ntom, thiab kwv yees li qhov loj ntawm cov nplej nplej. Yog tias flocs me me thiab hmoov -zoo li, nce coagulant. Yog hais tias cov tshuaj tiv thaiv tank zoo li nyias batter, koj tau overdosed.

Rau kev kho dej khib nyiab:Chemistry yog complex. Ntau yam coagulants yuav xav tau, ntxiv rau polyacrylamide (PAM) raws li kev pabcuam flocculant, thiab cov roj tshem tawm rau cov dej khib nyiab oily.Cov dej khib nyiab raw dej zoo yog qhov sib txawv heev-tshwj xeeb tshaj yog hauv cov ntawv thov kev lag luam steel, thiab tshwj xeeb tshaj yog cov dej khib nyiab txias txias, uas hloov pauv hauv pH, roj cov ntsiab lus, thiab cov khib nyiab thauj los ntawm ib teev mus rau ib teev. Tsau tshuaj dosing tus nqi yuav ua tsis tiav. Tus neeg teb xov tooj yuav tsum saib xyuas cov tshuaj tiv thaiv tank tsis tu ncua thiab kho.

Field diagnostic rau txias dov khib nyiab (alkaline + oily):

• Overdose coagulant:Cov tshuaj tiv thaiv tank zoo li batter. Tsis pub dhau ob peb teev, ib txheej ntawm cov ntaub ntawv ntab ntab rau ntawm lub raj dej nyob saum npoo -cov roj uas tau tshuaj lom neeg tso tawm tab sis tsis tuaj yeem sib cais vim tias cov qauv floc yog xoob dhau.

• Tsis tshua muaj coagulant:Txawm hais tias cov tshuaj tiv thaiv lub tank zoo li zoo, lub raj xa dej effluent nqa cov khib nyiab zoo. Cov flocs tsis muaj zog heev los tiv thaiv kev nce siab hauv cov hlab ntsha.

• Overdosed PAM:Loj, fluffy flocs nce hauv thaj chaw dej ntshiab saum cov hlab. Cov no yog PAM-bridged flocs uas kaw cua los yog pa npuas-hloov heev los daws.

• Kev noj tshuaj kom raug:Flocs hauv cov tshuaj tiv thaiv tank yog qhov loj ntawm mung taum, compact, nrog cov dej ntshiab pom ntawm lawv. Lub tube settler nto tseem meej; effluent zoo yog ruaj khov.

3.2 Sludge Discharge: Ntau zaus tshaj qhov koj xav

Vim tias lub raj xa dej kho cov dej ntim ntau hauv ib cheeb tsam, nws kujaccumulates sludge saiib cheeb tsam ib cheeb tsam dua li cov pa sedimentation tank. Lub sludge tawm zaus yuav tsum nce raws li. Qhov no tsis yog xaiv tau- cia cov sludge sib sau ua ke nyob rau hauv lub hopper tshaj nws cov qauv tsim ua rau:

• Sludge nkag mus rau thaj tsam anaerobic, tsim cov pa roj npuas uas nqa flocs

• Txo qhov ntim tau zoo, ua rau cov sludge tshiab ntws mus rau hauv thaj chaw faib khoom

• Phosphorus tso tawm los ntawm cov sludge lom nyob rau hauv cov ntaub ntawv pov tseg, ua kom TP effluent

Txoj cai ntawm tus ntiv tes xoo:Rau cov dej khib nyiab hauv nroog cov ntsiab lus qhia meej, tso cov sludge tsawg kawgtxhua 4-6 teevthaum ua haujlwm li qub. Rau siab - cov ntawv thov kev lag luam, kev tso tawm yuav tsum yogtxhua 1-2 teev. Teem lub zaus raws li cov khoom thauj khoom thauj khoom tus nqi- tsis yog nyob rau ntawm lub sijhawm teem tseg uas tau theej los ntawm cov lus qhia meej.

3.3 Floc Floatation: Ntsuam xyuas ua ntej koj kho

Thaum flocs tshwm nyob rau saum npoo ntawm thaj chaw dej ntshiab, ntau tus neeg ua haujlwm tam sim ntawd kho cov tshuaj tshuaj. Tab sis floc floatation muajntau yam ua tau, thiab cov lus teb tsis raug ua rau tej yam tsis zoo. Nov yog yuav kuaj tau li cas:

Peb txoj cai uas tiv thaiv cov teeb meem ntawm Tube Settler feem ntau

1. Khaws qhov nrawm nrawm qis dua 0.25 m / s thiab zam cov phab ntsa perforated.Cov flocs nkag mus rau hauv koj lub raj xa dej yuav tsum tsis muaj zog. Sheared flocs tsis rov ua dua - hauv cov raj xa dej. Kev hloov pauv qhib nrog kev ntws tawm -txoj kev ncaj baffle yog qhov tseeb inlet configuration rau upflow tube settlers.

2. Tsis txhob txo qis sludge hopper qhov siab hauv qab qhov tsawg kawg swb kaum.Lub hopper uas tsis swb sludge thaum kawg yuav mus septic, thiab tsis muaj dab tsi - tsis muaj tshuaj ntxiv, tsis nquag tso tawm ntau dua -yuav kho qhov teeb meem geometry. Lub hopper lub kaum sab xis yog teem los ntawm physics, tsis yog nyiaj txiag.

3. Ntsuam xyuas floc floatation ua ntej kho cov tshuaj.Flocs nyob rau saum npoo tuaj yeem txhais tau tias overdosing, underdosing, kub tam sim no, sludge gas, los yog huab cua nkag-txhua tus yuav tsum tau teb txawv kiag li. Ntxiv coagulant ntau dua rau qhov kub thiab txias - qhov teeb meem uas tau tsav qhov ceev tam sim no yuav tsis pab thiab yuav ua rau muaj teeb meem loj dua.

Tube settlers yog tam sim no siv tsis tau tsuas yog nyob rau hauv cov tsoos dej thiab cov dej khib nyiab kho tab sis nce nyob rau hauvua vaj tse wetlands, aquaculture recirculation systems, thiab industrial txheej txheem dej rov qab. Cov hauv paus ntsiab lus hauv kab lus no siv tau thoob plaws txhua daim ntawv thov-vim lub physics ntawm inclined phaj settling tsis hloov. Qhov kev hloov pauv li cas yog dej chemistry, cov yam ntxwv ntawm cov khib nyiab, thiab qhov tshwm sim ntawm kev tau txais cov ntsiab lus tsis raug.

Tube settler media zoo tseem ceeb heev.Channel geometry (feem ntau yog 25-80 hli hydraulic txoj kab uas hla), daim ntawv tuab (0.5-1.2 hli), cov khoom siv (PP rau kev siv dav dav, PVC rau qhov kub thiab txias los yog tshuaj tiv thaiv), thiab kev txhim kho qib tag nrho cuam tshuam rau koj qhov kev teeb tsa ua tau zoo npaum li cas los tsim cov txiaj ntsig.Juntai muab PP thiab PVC tube settler medianyob rau hauv ntau yam specifications - tiv tauj peb nrog koj tus qauv tsim rau kev pom zoo.
