Tag nrho Suspended Solids (TSS) Thiab Turbidity: Ob qhov tseem ceeb tab sis feem ntau tsis pom zoo cuam tshuam rau UV dej tua kab mob kev ua tau zoo

Thaum xaiv thiab qhia txog UV dej tua kab mob, ntau tus neeg yuav khoom tsom mus rau qhov tsis xws li UV siv, lub sij hawm raug, thiab koob tshuaj UV. Cov yam tseem ceeb no yog qhov tseeb cov ntsiab lus uas txiav txim siab qhov kev ua haujlwm theoretical ntawm chav tsev tshuaj tua kab mob UV.
Txawm li cas los xij, hauv tiag -kev siv dej hauv ntiaj teb,Tag nrho Suspended Solids (TSS) thiab turbidity yog ob qho tseem ceeb ntawm sab nraud uas cuam tshuam rau kev tua kab mob, tab sis lawv feem ntau tsis saib xyuas..

1. Vim li cas TSS thiab Turbidity ua rau UV Dose Attenuation?

1.1 TSS yog dab tsi, thiab Nws txawv ntawm TDS li cas?

TSS (Total Suspended Solids)hais txog tag nrho cov nqi ntawm cov khoom tsis sib haum uas tau muab tshem tawm hauv dej, suav nrog cov xuab zeb, xeb, cov khib nyiab organic, thiab cov kab mob sib sau ua ke.
Tsis zoo li TDS (Tag nrho Dissolved Solids), TSS tsis cuam tshuam rau saj, tab sis nws muaj ib qhocuam ​​tshuam ncaj qha rau kev kho dej.

Hauv UV dej tshuaj tua kab mob, cov khoom raug tshem tawm tuaj yeem thaiv thiab tawg hluav taws xob ultraviolet, txo qhov tseeb UVC koob tshuaj tau txais los ntawm cov kab mob. Yog li ntawd, TSS yog atseem ceeb tab sis nquag underestimated parameteruas ncaj qha cuam tshuam cov tshuaj tua kab mob.

1.2 Turbidity yog dab tsi?

turbidityyog ib qho kev ntsuas ntawm cov dej ntshiab thiab muaj kev cuam tshuam txog qib uas tshem tawm cov khoom tawg thiab nqus lub teeb. Cov turbidity siab dua qhia tau tias muaj ntau dua ntawm cov khib nyiab tshem tawm xws li cov av, colloids, organic teeb meem, los yog kab mob, ua rau pom dej "pos huab".

Hauv kev kho dej thiab tshuaj tua kab mob UV, turbidity tsis yog qhov kev txhawj xeeb ntawm qhov muag. Nwsncaj qha txo UV nkag qhov tob, yog li txo cov tshuaj tua kab mob zoo. Vim li no, turbidity yog qhov tseem ceeb rau kev ntsuas ob qho tib si dej zoo thiab kev ntseeg siab ntawm UV tshuaj tua kab mob.

Qhov txawv ntawm Turbidity thiab TSS

1.3 Cov txheej txheem tseem ceeb los ntawm TSS thiab Turbidity Txo UV Disinfection Efficiency

• Tiv thaiv lub cev (Shadowing Effect)
Cov khoom raug tshem tawm tuaj yeem tiv thaiv kab mob, tso cov kab mob thiab cov kab mob hauv thaj tsam "shadowed" uas UV hluav taws xob tsis tuaj yeem ncav cuag lawv ncaj qha. Cov kab mob uas zais tom qab lossis hauv cov khoom tuaj yeem muaj sia nyob txawm tias UV teeb ua haujlwm ib txwm ua, ua rau txo cov tshuaj tua kab mob.

• UV Scattering thiab Absorption
Tshem tawm cov khib nyiab, colloids, thiab cov khoom zoo ua kom tawg thiab nqus cov hluav taws xob ultraviolet, txo cov UVC lub zog uas ua rau cov kab mob.
Raws li turbidity nce thiab particle loj txo qis, tawg ua rau hnyav dua, UV nkag mus deb, thiab tag nrho cov tshuaj tua kab mob txo qis.

2. Vim li cas Kev Lag Luam Re-Tsom rau TSS?

Nyob rau hauv xyoo tas los no, kev lag luam kho dej tau rov ua dua nws txoj kev tsom mus rauTSS, tshwj xeeb tshaj yog nyob rau hauv industrial water, municipal reclaimed water, food and drink processing, thiab kev siv tshuaj. Cov txheej txheem thiab cov txheej txheem tau tsim cov kev cai nruj ntxiv rauturbidity (NTU)thiabTSS (mg/L).

Cov kev paub dhau los tau pom tias muaj ntau yam teeb meem kev ua haujlwm ntawm UV tua kab mobtsis yog tshwm sim los ntawm lub teeb tsis ua hauj lwm lossis lub zog tsis txaus, tab sis los ntawm kev tswj tsis txaus ntawm cov dej ntws zoo. Kev nce qib ntawm cov khib nyiab pov tseg thiab turbidity thaiv thiab tawg tawg UV hluav taws xob, tiv thaiv cov kab mob kom tsis txhob raug txaus.

Hauv cov ntsiab lus no,TDS feem ntau yog cov neeg siv khoom- taw qhia qhov ntsuas ntsig txog saj, hosTSS yog ib qho kev nyab xeeb ntawm engineering. Hauv UV tshuaj tua kab mob, qhov cuam tshuam ntawm TSS ntawm cov tshuaj tua kab mob yog ntau dua li ntawm TDS, tab sis nws tau ntev tau underestimated.

Kev tswj kom zoo ntawm TSS yog qhov tseem ceeb rau kev ua kom muaj txiaj ntsig zoo, txhim khu kev qha kev ua haujlwm thiab sawv cev rau kev saib xyuas kev nyab xeeb tseem ceeb hauv kev kho dej niaj hnub engineering.

3. Thaum Hloov Cov Khoom Siv, "System Design Matters More than Hardware"

Rau cov neeg yuav khoom, chav dej tshuaj tua kab mob UV yuav tsum tsis txhob saib raws li cov khoom siv ib leeg, tab sis raws li lub kaw lus uas cuam tshuam nrog cov dej tsis zoo. Tsis quav ntsej TSS thiab turbidity feem ntau ua rau cov nqi zais ntev -, xws li microbial ntau dhau thiab luv lub teeb lub neej.

Cov haujlwm kho dej yav tom ntej yuav tsum tau txais kev pom zoo dua:

Ntsuam xyuas ib puag ncig, tsis yog cov specifications xwb:
Ntxiv rau qhov yuav tsum tau txhaj tshuaj tiv thaiv UV, kev ntsuas qhov tseeb ntawm TSS thiab turbidity yuav tsum tau muab.

Ua ntej qhov kev ruaj ntseg tshaj qhov ua tau zoo tshaj plaws:
High-cov tshuab UV zoo yuav tsum tsim kom muaj kev rov ua dua kom txaus los tswj cov dej tsis zoo.

4. Dab tsi ntawm TSS thiab turbidity yuav tsum tau tswj nyob rau hauv kev siv engineering siv?

Nyob rau hauv UV dej tua kab mob, tsis muaj TSS kiag li los yog turbidity tus nqi uas siv universally rau txhua daim ntawv thov. Kev tswj hwm qhov tsim nyog nyob ntawm qhov kev thov scenario, qib kev pheej hmoo microbial, thiab kev tsim cov txheej txheem redundancy.

Txawm li cas los xij, ntev - lub sij hawm engineering xyaum tau tsim cov kev siv dav dav uas tuaj yeem ua cov lus qhia tseem ceeb rau kev xaiv thiab tsim qauv.
