Iulai 15, 2021 – CHICAGO.I aso nei, o Jiangxi JDL Environmental Protection Co Ltd, (SHA: 688057) na tuʻuina atu faʻaiʻuga o se suʻesuʻega faʻataʻitaʻiga DNA na faia e Microbe Detectives 'e faʻatatauina uiga faʻapitoa o le aveesea o meaʻai o le JDL's pateni FMBR faagasologa.
O le Facultative Membrane Bio-Reactor (FMBR) o se faiga faʻapitoa faʻapitoa mo le faʻaogaina o le suavai otaota e faʻaumatia ai le kaponi (C), nitrogen (N), ma le phosphorus (P) i se tulaga maualalo DO (<0.5 mg / L), i le laasaga e tasi. .Ole mea lea e mafai ai ona fa'asaoina tele le malosi ma se tulaga la'ititi la'ititi, pe a fa'atusatusa ile fa'agasologa masani ole su'esu'eina ole suavai leaga e mana'omia ai le tele o fa'agaioiga.Faitau atili ilewatertrust.com/fmbr-study.
Talu mai le fa'atonuina ia Novema 2019, ua suia ai e le JDL's FMBR Pilot Demonstration i Amerika se talatu'u fa'asologa fa'asologa o mea fa'atupu (SBR), e fa'agaioia le 5,000 GPD o vai otaota na gaosia e le Plymouth Massachusetts Municipal Airport ma fale'aiga lata ane.O faʻamanuiaga faʻamaonia e aofia ai:
- 77% fa'asao malosi pe a fa'atusatusa i le SBR ua sui
- 65% fa'aitiitiga o le voluma biosolids e mana'omia le lafoai i fafo
- 75% laʻititi tulagavae
- 30 aso faʻapipiʻi
O le Microbe Detectives (MD) na fa'aogaina ana metotia fa'asologa 16S DNA, fa'apitoa mo su'esu'ega BNR vai otaota, e fa'avasega ai fa'ata'ita'iga e 13 o le FMBR Pilot na aoina i le tausaga e tasi.O le fa'amoemoe o le fesoasoani lea i le JDL e va'ai, fua, ma pulea le microbiome FMBR mo le fa'atinoina lelei o le fa'aaogaina o mea'ai.
I se poloketi 2nd vaega, MD faʻatusatusa faʻamaumauga DNA o faʻataʻitaʻiga a le FMBR Pilot, i faʻamaumauga MD DNA o 675 faʻataʻitaʻiga mai le 18 faʻataʻitaʻiga ole vai otaota a le taulaga BNR, faʻasalalau i New England, Midwest, Southwest, Rocky Mountains, ma West Coast geographies i Amerika.O fa'amaumauga uma sa le'i fa'ailoaina.
O faʻamaumauga a le DNA na faʻamaonia ai le FMBR Pilot system e masani lava ona faʻaogaina siama Nitrification / Denitrification (SND) faʻatasi e aveese ai le nitrogen, lea e manaʻomia ai le 20-30% le itiiti ifo o le okesene ma le 40% itiiti le carbon nai lo auala masani.Ua fa'aliliuina lea i le 77% o le fa'asaoina o le malosi.Dechloromonas(pe. 8.3% ile FMBR vs 1.0% ile BNR fa'ailoga) maPseudomonas(ave. 8.1% i FMBR vs 3.1% i BNR benchmarks) o SND sili ona tele na matauina i le FMBR.
Tetrasphaera(ave. 4.0% i FMBR vs 2.4% i BNR benchmarks), o le Denitrifying Phosphorus Accumulating Organism (DPAO), sa matauina foi i le maualuga o le tele i le FMBR.SND ma le DPAO siama, e malosi atu le manava manava.Na fa'aliliuina i se fa'aitiitiga o le gaosiga o le palapala ile 50%.Faatasi ai ma isi mea, o le aofaʻi o biosolids faaletausaga e manaʻomia ai le lafoai i fafo na faʻaititia i le 65%.
