Chav ua noj cov khoom pov tseg hauv chav ua noj ua rau cov khoom siv cov pa roj carbon monoxide nce mus txog qhov chaw kho dej, uas ua rau nce kev noj cov pa oxygen.Metcalf thiab Eddy tau txheeb xyuas qhov cuam tshuam no li 0.04 phaus (18 g) ntawm biochemical oxygen xav tau rau ib tus neeg hauv ib hnub uas siv cov khoom pov tseg.] Ib txoj kev tshawb fawb Australian uas piv rau cov khoom noj hauv lub dab ntxuav muag rau kev sib xyaw ua lwm yam los ntawm kev ntsuas lub neej-khiav pom tias thaum lub Cov khoom pov tseg hauv lub dab dej ua tau zoo nrog rau kev hloov pauv huab cua, acidification, thiab kev siv lub zog, nws tau pab txhawb rau eutrophication thiab toxicity peev xwm.
Qhov no yuav ua rau cov nqi siab dua rau lub zog xav tau los muab cov pa oxygen hauv cov haujlwm thib ob.Txawm li cas los xij, yog tias kev kho dej khib nyiab raug tswj kom zoo, cov organic carbon hauv cov zaub mov yuav pab kom cov kab mob decomposition khiav, vim tias cov pa roj carbon monoxide yuav tsis muaj nyob hauv cov txheej txheem ntawd.Cov pa roj carbon ntau ntxiv no ua haujlwm pheej yig thiab tsis tu ncua ntawm cov pa roj carbon tsim nyog rau kev tshem tawm cov khoom noj biologic.
Ib qho txiaj ntsig yog qhov loj dua ntawm cov khoom seem ntawm cov txheej txheem dej khib nyiab.Raws li kev tshawb fawb ntawm East Bay Municipal Utility District qhov chaw kho dej khib nyiab tau txais nyiaj los ntawm EPA, cov khoom noj khib nyiab tsim peb zaug ntawm biogas piv rau cov dej phwj hauv nroog.Tus nqi ntawm cov biogas uas tsim los ntawm kev zom cov zaub mov pov tseg zoo li ntau dua tus nqi ntawm kev ua cov zaub mov pov tseg thiab pov tseg cov biosolids seem (raws li LAX Tshav Dav Hlau pom zoo kom hloov 8,000 tons / xyoo ntawm cov khoom noj khoom haus ntau).
Hauv kev tshawb fawb ntawm Hyperion dej phwj kho cog hauv Los Angeles, kev siv pov tseg tau pom tsawg kawg nkaus kom tsis muaj kev cuam tshuam rau tag nrho biosolids byproduct los ntawm kev kho dej phwj thiab zoo ib yam li kev cuam tshuam tsawg kawg nkaus ntawm kev tuav cov txheej txheem raws li cov khoom tawg yooj yim heev (VSD) los ntawm cov khoom pov tseg cov khoom noj tsawg kawg nkaus. tus nqi ntawm cov khoom nyob rau hauv residue.
Kev siv hluav taws xob feem ntau yog 500–1,500 W, piv rau cov hlau hluav taws xob, tab sis tsuas yog lub sijhawm luv luv xwb, tag nrho kwv yees li 3-4 kWh ntawm hluav taws xob ib tsev neeg hauv ib xyoos.] Kev siv dej txhua hnub sib txawv, tab sis feem ntau yog 1 US nkas loos (3.8). L) dej ntawm ib tus neeg hauv ib hnub, piv rau qhov tso quav ntxiv.Ib qho kev tshawb fawb ntawm cov chaw ua zaub mov no pom tias muaj kev siv dej hauv tsev me me.
