Hōngongoi 15, 2021 – CHICAGO.I tenei ra, i tukuna e Jiangxi JDL Environmental Protection Co Ltd, (SHA: 688057) nga hua o te rangahau tohu tohu DNA i whakahaeretia e Microbe Detectives 'e whakatau ana i nga ahuatanga tango matūkai koiora ahurei o te tukanga FMBR arai a JDL.
Ko te Facultative Membrane Bio-Reactor (FMBR) he tukanga maimoatanga wai para koiora ahurei e tango ana i te waro (C), te hauota (N), me te ūkuikui (P) i roto i te ahua DO iti (<0.5 mg/L), i roto i te taahiraa kotahi. .Ma tenei ka taea te penapena hiko me te iti ake o te tapuwae, ka whakaritea ki nga tikanga maimoatanga wai para tuku iho e hiahia ana kia maha nga waahanga tukatuka.Pānuitia atu iwatertrust.com/fmbr-study.
Mai i te whakaturanga i te Whiringa-a-rangi 2019, ko te Whakaaturanga Kaiurungi FMBR a JDL i USA kua whakakapi i tetahi reactor puranga raupapa (SBR), ki te tukatuka i te 5,000 GPD o te wai para i hangaia e te Plymouth Massachusetts Municipal Airport me nga wharekai huri noa.Ko nga painga kua tuhia ko:
- 77% te penapena hiko ina whakaritea ki te punaha SBR kua whakakapia
- 65% te whakahekenga o te rōrahi biosolids me tuku ki waho o te waahi
- 75% iti ake te tapuwae
- 30 ra te whakaurunga
I whakamahia e Microbe Detectives (MD) ana tikanga raupapa 16S DNA paerewa, he mea motuhake mo te tātari BNR wai para, ki te tātari 13 tauira o te FMBR Pilot i kohia i roto i te kotahi tau.Ko te kaupapa he awhina i a JDL ki te kite, ki te ine, ki te whakahaere i te microbiome FMBR mo te mahi tango matūkai tino pai.
I roto i te kaupapa 2nd, ka whakatauritehia e MD nga raraunga DNA o nga tauira Pilot FMBR, ki nga raraunga MD DNA o nga tauira 675 mai i nga tukanga BNR wai paru a te taone nui, i marara puta noa i New England, Midwest, Southwest, Rocky Mountains, me nga whenua o te Tai Hauauru i Amerika.I whakaingoatia nga raraunga katoa.
I whakapumautia e nga raraunga DNA ko te punaha Pilot FMBR te nuinga o te whakamahi i nga huakita Nitrification / Denitrification (SND) ki te tango i te hauota, me 20-30% te iti o te hāora me te 40% te iti o te waro i nga tikanga tuku iho.I whakamaoritia tenei ki te 77% te penapena hiko.Dechloromonas(taurite 8.3% i roto i te FMBR ki te 1.0% i roto i nga tohu tohu BNR) mePseudomonas(avg. 8.1% in FMBR vs 3.1% in BNR benchmarks) ko nga SND tino nui i kitea i roto i te FMBR.
Tetrasphaera(avg. 4.0% in FMBR vs 2.4% in BNR benchmarks), he Denitrifying Phosphorus Accumulating Organism (DPAO), i kitea hoki i roto i te nui o te nui i roto i te FMBR.Ko te huakita SND me te DPAO, he kaha ake te manawa o roto.I whakamaoritia tenei ki te whakahekenga o te hanga paru ma te 50%.Ka honoa ki etahi atu mea, ka whakahekehia te rahinga biosolids-a-tau e hiahia ana kia whakakorea ki waho ma te 65%.
