Kuchotsa munthawi yomweyo C, N, ndi P mu Low Energy FMBR Decentralized Wastewater Treatment System, Kutsimikiziridwa ndi DNA Study

Julayi 15, 2021 - CHICAGO.Lero, Jiangxi JDL Environmental Protection Co Ltd, (SHA: 688057) yatulutsa zotsatira za kafukufuku wa DNA wopangidwa ndi Microbe Detectives' womwe umatsimikizira mawonekedwe apadera ochotsa michere munjira ya JDL yovomerezeka ya FMBR.

Facultative Membrane Bio-Reactor (FMBR) ndi njira yapadera yoyeretsera madzi onyansa achilengedwe omwe amachotsa nthawi imodzi mpweya (C), nayitrogeni (N), ndi phosphorous (P) mumkhalidwe wochepa wa DO (<0.5 mg/L), mu sitepe imodzi. .Izi zimathandizira kupulumutsa mphamvu kwambiri komanso kutsika pang'ono, poyerekeza ndi njira zachikhalidwe zoyeretsera madzi anyasi zomwe zimafunikira magawo angapo okonza.Werengani zambiri pawatertrust.com/fmbr-study.

Chiyambireni ntchito mu Novembala 2019, JDL's FMBR Pilot Demonstration ku USA yalowa m'malo mwa sequencing batch reactor (SBR), kukonza 5,000 GPD yamadzi onyansa opangidwa ndi Plymouth Massachusetts Municipal Airport ndi malo odyera ozungulira.Zopindulitsa zomwe zalembedwa zikuphatikiza:

• 77% yopulumutsa mphamvu poyerekeza ndi makina osinthidwa a SBR
• Kuchepetsa 65% ya kuchuluka kwa biosolids komwe kumafunikira kutayidwa
• 75% yocheperako
• 30 tsiku unsembe

Ma Microbe Detectives (MD) adagwiritsa ntchito njira zake zotsatizana za 16S DNA, zapadera pakusanthula kwamadzi onyansa a BNR, kusanthula zitsanzo 13 za FMBR Pilot yomwe idasonkhanitsidwa kwa chaka chimodzi.Cholinga chake chinali kuthandiza JDL kuwona, kuyeza, ndikuwongolera ma microbiome a FMBR kuti agwire bwino ntchito yochotsa michere.

Mu pulojekiti ya gawo lachiwiri, MD inayerekeza deta ya DNA ya zitsanzo za FMBR Pilot, ndi deta ya MD DNA ya zitsanzo 675 kuchokera ku njira 18 za madzi onyansa a BNR, omwazikana ku New England, Midwest, Southwest, Rocky Mountains, ndi West Coast geographies ku USA.Zambiri sizinatchulidwe.

Deta ya DNA inatsimikizira kuti FMBR Pilot system makamaka imagwiritsa ntchito mabakiteriya a Simultaneous Nitrification / Denitrification (SND) kuchotsa nayitrogeni, yomwe imafuna 20-30% yochepa ya okosijeni ndi 40% yochepa ya carbon kusiyana ndi njira zachikhalidwe.Izi zasintha kukhala 77% yopulumutsa mphamvu.Dechloromonas(avg. 8.3% mu FMBR vs 1.0% mu BNR benchmarks) ndiPseudomonas(avg. 8.1% mu FMBR vs 3.1% mu zizindikiro za BNR) anali ma SND ochuluka kwambiri omwe anawonedwa mu FMBR.

Tetrasphaera(avg. 4.0% mu FMBR vs 2.4% mu BNR benchmarks), a Denitrifying Phosphorus Accumulating Organism (DPAO), adawonedwanso mochuluka kwambiri mu FMBR.Mabakiteriya a SND ndi DPAO, amakhala ndi kupuma kwamphamvu kwamkati.Izi zinapangitsa kuchepetsa kupanga zinyalala ndi 50%.Kuphatikiza ndi zinthu zina, voliyumu yapachaka ya biosolids yomwe imafunikira kuti ichotsedwe idachepetsedwa ndi 65%.

JDL Global Environmental Protection ndi katswiri pa kasamalidwe ka kuipitsidwa kwa madzi, Inc., wokhala ku New York.Ndi kampani ya Jiangxi JDL Environmental protection Co., Ltd., yomwe ili ku Nanchang, China.Pogwiritsa ntchito tizirombo tomwe timapanga mwachilengedwe tomwe timapanga motsogozedwa ndi chilengedwe, FMBR imagwiritsa ntchito mphamvu zochepa kuposa njira zachikhalidwe zoyeretsera madzi oyipa.Tizilombo toyambitsa matenda timachotsa mpweya, nayitrogeni, ndi phosphorous munthawi imodzi kuti tikwaniritse zofunikira za chilolezo chotaya madzi.Mulingo wocheperako kwambiri wa biosolids watsala womwe umafunika kutayidwa.JDL inapanga FMBR mu 2008, ndipo tsopano ili ndi ma patent 47 ku USA, UK, France, Japan, China, ndi mayiko ena.Makina opitilira 3,000 akhazikitsidwa ndikutumidwa m'maiko 19.JDLGlobalWater.com

Akatswiri amadzi, ogwira ntchito, ndi asayansi amadalira ntchito zosanthula DNA za Microbe Detectives kuti awone, kuyeza, ndi kuwongolera tizilombo toyambitsa matenda timene timachotsa ndi kubweza Carbon (C), Nitrogen (N), ndi Phosphorus (P) kuchokera ku zinyalala, kugaya organic. kuwononga, ndi kupanga zinthu zoyeretsedwa zongowonjezedwanso.Kwa zaka zisanu ndi ziwiri zapitazi, MD yagwiritsa ntchito kutsatizana kwa DNA kwa m'badwo wotsatira kuti athandize kuthetsa mavuto a madzi ndi mwayi kwa ma municipalities, akatswiri otsogolera, ogulitsa zamakono, madera ndi mafakitale.Wophunzira wa 2014 wa Water Council BREW accelerator, MD adadziwika ndi 2015 Wisconsin Innovation Awards, 2017 WEF Gascoigne Award, ndi 2018 WEFTEC/BlueTech Research Innovation Showcase.MicrobeDetectives.com.
