01 Lub Luag Haujlwm Cornerstone ntawm Cov Txheej Txheem Txhawb
Ntau- cov ntxaij lim dej tawm yog cov cuab yeej tseem ceeb hauv kev kho dej niaj hnub no rau kev tshem tawm cov khib nyiab pov tseg. Lawv cov qauv tsim, los ntawm sab saum toj mus rau hauv qab, suav nrog cov txheej txheem pom zoo li anthracite, quartz xuab zeb, garnet, thiabtxhawb txheejhauv qab heev.
Txawm hais tias cov txheej txheem txhawb nqa tsis ncaj qha mus rau hauv kev pom, nws lub xub pwg ob lub luag haujlwm tseem ceeb: tiv thaiv kom tsis txhob poob ntawm cov lim dej zoo tshaj plaws los ntawm cov kab dej hauv qab thiab pab hauv cov dej tsis sib xws thaum rov qab ntxuav.
Ib txheej txheej kev txhawb nqa tsis zoo tuaj yeem ua rau kev sib xyaw ntawm cov xov xwm, xuab zeb to, thiab txawm tias tag nrho cov lim tsis ua haujlwm. Rau ib leeg lossis dual cov ntxaij lim dej uas siv lub siab -headloss underdrain system, pebbles ntuj yog cov khoom siv feem ntau siv.
02 Cov yam ntxwv tseem ceeb sib piv: Qhov sib txawv ntawm Pebble thiab pob zeb
Los ntawm kev pom geological, cov pob zeb tawg loj dua 5 hli hauv txoj kab uas hla yog hu uapebblesyog zoo- sib npaug, thiabpob zebyog angular. Qhov sib txawv morphological no ua rau muaj kev sib txawv tseem ceeb.
Cov ncauj lus kom ntxaws sib piv ntawm lawv cov yam ntxwv yog raws li hauv qab no:
| Yam ntxwv | Pebble | Pob zeb |
|---|---|---|
| Roundness | Ib txwm puag ncig lossis sub- sib npaug, du nto | Angular lossis multi-angular, ntxhib nto |
| Hardness | Mohs hardness feem ntau mus txog7.5-7.6, hnav thiab compression -resistant | Nyob ntawm niam txiv pob zeb; quartz-raws li gravel siab, lwm tus yuav qis dua |
| Ntim Porosity | Tsawg dua(kwv yees . 30-40%), cov khoom ntim kom nruj | kwv yees siab dua(tuaj yeem ncav cuag 45% lossis ntau dua), angularity tsim ntau qhov chaw interstitial |
| Siv tau Scenarios | Cov ntxaij lim dej yuav tsum muaj kev ruaj khov thiab kev faib tawm tsis sib xws; systems valueing backwash efficiency thiab ntev -lub sij hawm stability | Cov txaj tshwj xeeb lim yuav tsum muaj qhov porosity siab rau kev ntws los yog biofilm txuas; scenarios nrog qis xav tau rau kev faib uniformity |
Kev sib piv ntawm cov yam ntxwv tseem ceeb ntawm Pebble thiab Gravel
Ntuj pebbles yog tsim los ntawm fluvial thauj thiab deposition, featuring spherical duab thiab siab glossiness. Lawv yog siab-resistant, hnav-resistant, thiab yooj yim rau rov qab ntxuav. Pob zeb feem ntau yog tsim los ntawm mechanically crushing pob zeb; nws cov duab angular tsim ib lub pob porosity loj dua.
Los ntawm kev xav hydraulic, lubspherical nto ntawm pebbles ho txo ndlwg kuj, tso dej kom dhau los ntawm cov txheej txheem txhawb nqa ntau dua, uas yog qhov tseem ceeb rau kev tswj xyuas kev ruaj ntseg. Cov npoo ntse ntawm pob zeb tuaj yeem ua rau muaj kev kub ntxhov hauv zos, ua rau lub taub hau tsis tsim nyog.
03 Precise Selection Strategy
Tsib yam tseem ceeb yuav tsum tau xav txog thaum xaiv cov ntaub ntawv txhawb nqa.
Thawj yogGrain Size Distribution. Cov txheej txheem txhawb nqa yuav tsum ua raws li lub hauv paus ntsiab lus ntawm "coarse nyob rau hauv qab, zoo rau saum"Kev gradation xws li specifications xws li 2-4mm, 4-8mm, 8-16mm, 16-32mm, 32-64mm.
Hauv kev tsim cov gravel lim txaj tsim, txoj kab uas hla loj dua (40-80 mm) pebbles yog siv nyob rau hauv qhov chaw nkag mus kom txo qis kev pheej hmoo clogging.
Qhov thib ob yogSystem Compatibility. Rau triple - media filters, vim yog qhov me me thiab lub ntiajteb txawj nqus siab ntawm qis lim xov xwm, yuav tsum muaj txheej txheem hnyav. Tsawg-headloss underdrain systems tej zaum yuav tshem tawm cov txheej txheem los yog siv cov xuab zeb ntxhib lossis pob zeb zoo.
Peb yogTshuaj Stability. Nyob rau hauv acidic los yog corrosive ib puag ncig, cov ntaub ntawv uas muaj zog acid kuj thiab corrosion kuj yuav tsum tau ua ntej. Qee cov nroj tsuag tshuaj tshwj xeeb xaiv cov pebbles dub.
Plaub yogNtev -Lub Sij Hawm Ntev. Pebble lim xov xwm nrog Mohs hardness saum 7.5 tuaj yeem tiv taus hnav los ntawm kev rov ua dua rov qab.
Thaum kawg,Supplier Expertise. Ib tus kws tshaj lij kev lag luam yuav tsum muab cov ntaub ntawv qhia txog qhov loj me me, cov ntaub ntawv kev ruaj ntseg tshuaj, thiab kev txhawb nqa.
04 Peb Qhov Zoo Tshaj Plaws: Mechanically Polished Pebbles
Raws li kev nkag siab tob txog kev xav tau kev lag luam, peb tau tsim cov khoom tshiab:Mechanically Polished Pebbles. Muab piv rau cov pob zeb ntuj qub, peb cov khoom tau dhau los ua polishing tshwj xeeb, muab cov txiaj ntsig zoo.
Lub tshuab polishing txheej txheem rub los ntawm kev vibration sib tsoo tshuab hauv kev ua pob zeb. Multi-stage kev sib tsoo ua tiav ib qho chaw du heev thaum tuav lub ntuj daim ntawv.
Cov txheej txheem no muab ob qho txiaj ntsig zoo: Ua ntej, ance ntau hauv qhov smoothness, txo kev sib txhuam ntws los ntawm kwv yees li 15-20% piv rau cov pebbles ib txwm muaj, txo qis zog siv zog. Thib ob,optimized duab uniformity, kom ntseeg tau tias cov txheej txheem nruj dua thiab ruaj khov.
Rau siab -load lim uas yuav tsum tau rov qab ntxuav tas li, peb cov Mechanically Polished Pebbles txo cov khoom zoo uas tsim los ntawm kev puas tsuaj, txuas ntxiv kev pab cuam lub neej. Nyob rau tib lub sijhawm, qhov chaw du yog yooj yim dua los ntxuav kom huv si, tswj xyuas cov yam ntxwv hydraulic ruaj khov ntev -lub sijhawm.
Peb Cov Mechanically Polished Pebbles nruj me ntsis ua raws li tus qauv CJ24-1-88, muaj qhov tshwj xeeb ntawm thaj chaw zoo, muaj zog txhua yam, thiab tsis muaj impurities, ua rau lawv qhov kev xaiv zoo tshaj plaws rau cov khaubncaws sab nraud povtseg hauv ntau lub tshuab lim.
05 Cov Lus Nug: Txhawb Cov Txheej Txheem Qhov siab suav
Q: Yuav ua li cas txiav txim siab qhov siab tsim nyog rau txheej txheej txhawb nqa hauv ntau- lim xov xwm?
Qhov siab tsim ntawm cov txheej txheem txhawb nqa yuav tsum tau ua tib zoo xav txog yam xws li hom lim dej, qhov system underdrain, cov yam ntxwv ntawm cov lim dej sab saud, thiab kev kho tus nqi ntws. Feem ntau, tag nrho cov kev txhawb nqa txheej siab yog nyob ntawm0.3 rau 0.5 m, nteg nyob rau hauv graded txheej.
Siv cov ntaub ntawv engineering tiag tiag: tsim cov txheej txheem lim dej aerated nrog kev kho lub peev xwm ntawm 10,000 m³ / hnub, siv 4 lim hlwb nrog cov phiaj xwm qhov ntev ntawm 6.0 × 6.0 meters, thiab tag nrho lim xov xwm qhov siab ntawm 3.3 meters.
Hauv qhov kev tsim no, qhov kev txhawb nqa txheej siab yog teem rau0,4m ib. Cov txheej txheem lim dej los ntawm sab saum toj mus rau hauv qab yog: thaj chaw dej ntshiab 1.0m, txheej txheej txheej 3.3m, txhawb txheej txheej 0.4m, lim phaj 0.1m, dej faib thaj tsam 1.2m, ntxiv rau qhov chaw dawb 0.5m, ua rau tag nrho qhov siab ntawm 6.5 meters.
Cov txheej txheem txheej txheej no ua kom ruaj khov ua haujlwm- txheej txheej txhawb nqa yuav tsum tsis yog tsuas yog txhawb nqa 3.3-meter tuab txheej txheej saum toj no tab sis kuj tseem faib cov dej ntws tawm thaum rov qab los tiv thaiv kev tawm xov xwm.
Hauv kev xam tshwj xeeb, engineers xav txog yam xws li backwash siv, media particle size, thiab underdrain system hom, siv hydraulic xam los txiav txim qhov siab thiab grain loj rau txhua txheej. Feem ntau, pib los ntawm cov txheej hauv qab (qhov loj tshaj plaws), qhov loj me me yog maj mam txo kom txog thaum nws phim cov lim dej sab saud.
Thaum dej dhau los ntawm qhov khoob ntawm cov pob zeb polished rau lub sijhawm kawg, lub lim ua tiav lwm lub voj voog pom zoo. Cov pob zeb zoo li no zoo ib yamntsiag to txhawb ob peb tons ntawm lim xov xwm saum toj no, xyuas kom txhua tee dej raug kho kom zoo.
Nyob rau hauv ib txoj haujlwm kho dua tshiab ntawm cov chaw kho dej loj nyob rau sab qab teb Suav teb, hloov cov txheej txheem pob zeb sib xyaw nrog Mechanically Polished Pebbles ua rau 30% txuas ntxiv ntawm lub voj voog rov qab thiab 8% txo qis hauv ib xyoos ib zaug. Qhov no ua pov thawj tias qhov kev xaiv kws tshaj lij txhais tau li cas rau - cov txiaj ntsig kev ua haujlwm ntev.
