Lub Xya Hli 15, 2021 - CHICAGO.Niaj hnub no, Jiangxi JDL Environmental Protection Co Ltd, (SHA: 688057) tau tshaj tawm cov txiaj ntsig ntawm DNA benchmarking txoj kev tshawb fawb los ntawm Microbe Detectives ' uas ntsuas qhov tshwj xeeb ntawm cov khoom noj khoom haus tshem tawm ntawm JDL's patented FMBR txheej txheem.
Lub Facultative Membrane Bio-Reactor (FMBR) yog cov txheej txheem kev kho dej khib nyiab lom zem uas ib txhij tshem tawm cov pa roj carbon (C), nitrogen (N), thiab phosphorus (P) nyob rau hauv qhov tsis tshua muaj DO (<0.5 mg / L), hauv ib kauj ruam txheej txheem. .Qhov no ua rau muaj kev txuag hluav taws xob tseem ceeb thiab kev hneev taw me dua, piv rau cov txheej txheem kev kho dej khib nyiab uas yuav tsum tau ua ntau yam.Nyeem ntxiv ntawmwatertrust.com/fmbr-study.
Txij li thaum pib lub Kaum Ib Hlis 2019, JDL's FMBR Pilot Demonstration nyob rau hauv Teb Chaws Asmeskas tau hloov qhov qub txeeg qub teg batch reactor (SBR), ua 5,000 GPD ntawm cov dej khib nyiab tsim los ntawm Plymouth Massachusetts Municipal Tshav Dav Hlau thiab cov khw noj mov nyob ib puag ncig.Cov txiaj ntsig tau sau tseg muaj xws li:
- 77% kev txuag hluav taws xob piv rau qhov hloov SBR system
- 65% txo qis ntawm biosolids ntim yuav tsum tau muab pov tseg tawm ntawm qhov chaw
- 75% me dua hneev taw
- 30 hnub installation
Microbe Detectives (MD) tau siv nws cov qauv 16S DNA sequencing txoj kev, tshwj xeeb rau cov dej khib nyiab BNR tsom xam, los tshuaj xyuas 13 cov qauv ntawm FMBR Pilot sau ntau tshaj ib xyoos.Lub hom phiaj yog los pab JDL pom, ntsuas, thiab tswj FMBR microbiome rau kev ua tau zoo tshem tawm cov zaub mov zoo.
Hauv 2nd theem project, MD piv DNA cov ntaub ntawv ntawm FMBR Pilot cov qauv, rau MD DNA cov ntaub ntawv ntawm 675 cov qauv los ntawm 18 lub nroog cov dej khib nyiab BNR cov txheej txheem, tawg thoob plaws New England, Midwest, Southwest, Rocky Mountains, thiab West Coast thaj chaw hauv Tebchaws Meskas.Tag nrho cov ntaub ntawv tsis qhia npe.
DNA cov ntaub ntawv tau lees tias FMBR Pilot system feem ntau siv cov kab mob Simultaneous Nitrification / Denitrification (SND) kom tshem tawm nitrogen, uas yuav tsum tau 20-30% oxygen tsawg thiab 40% carbon tsawg dua li cov txheej txheem ib txwm muaj.Qhov no txhais ua 77% kev txuag hluav taws xob.Dechloromonas(avg. 8.3% hauv FMBR vs 1.0% hauv BNR cov qauv) thiabPseudomonas(avg. 8.1% hauv FMBR vs 3.1% hauv BNR cov qauv ntsuas) yog qhov ntau tshaj SNDs pom hauv FMBR.
Tetrasphaera(avg. 4.0% hauv FMBR vs 2.4% hauv BNR cov qauv ntsuas), ib qho Denitrifying Phosphorus Accumulating Organism (DPAO), kuj tau pom muaj ntau hauv FMBR.SND thiab DPAO cov kab mob, muaj zog ua pa endogenous.Qhov no txhais ua kom txo qis hauv sludge ntau lawm los ntawm 50%.Ua ke nrog lwm yam, txhua xyoo biosolids ntim yuav tsum tau muab pov tseg tawm ntawm qhov chaw raug txo los ntawm 65%.
