Cov chaw saib xyuas kev noj qab haus huv hauv nroog yog cov chaw pabcuam kev noj qab haus huv rau pej xeem tau tsim los ntawm tsoomfwv, thiab yog lub hub ntawm Tuam Tshoj txoj kev pabcuam kev noj qab haus huv peb theem.Lawv lub luag haujlwm tseem ceeb yog kev pabcuam kev noj qab haus huv rau pej xeem, muab cov kev pabcuam zoo xws li kev tiv thaiv kev noj qab haus huv, kev kawm txog kev noj qab haus huv, kev kho mob yooj yim, tshuaj suav tshuaj, thiab kev qhia txog kev npaj tsev neeg rau cov neeg nyob deb nroog.Nws ua lub luag haujlwm tseem ceeb hauv kev daws cov teeb meem kub xws li kev kho mob nyuaj thiab kim heev rau cov pej xeem.
Cov chaw saib xyuas kev noj qab haus huv hauv nroog feem ntau nyob hauv thaj chaw deb nroog tsis muaj cov kav dej hauv nroog, thiab cov dej phwj tuaj yeem tsuas yog tso ncaj qha, ua rau ib puag ncig zoo thiab ua rau muaj kev puas tsuaj loj rau tib neeg lub neej.Nyob rau tib lub sijhawm, cov dej phwj tuaj los ntawm lub chaw saib xyuas kev noj qab haus huv tau tso rau hauv cov dej nyob ze yam tsis muaj kev kho mob, ua rau muaj kuab paug rau hauv av, thiab lub tsev kho mob cov khib nyiab yog ib feem ntawm cov tshuaj lom, ua rau muaj kev pheej hmoo kis tus kabmob mus rau tib neeg.Txhawm rau tiv thaiv ib puag ncig ecological nyob ib puag ncig hauv nroog, txhawb kev txhim kho kev lag luam kom ruaj khov, tiv thaiv kev nyab xeeb ntawm tib neeg lub neej, thiab xyuas kom cov neeg tsim khoom tsis cuam tshuam, nws yog qhov tsim nyog thiab tsim nyog los tsim kho.Kev kho dej phwj tuajekhoom siv.
Cov dej phwj tuaj ntawm cov chaw saib xyuas kev noj qab haus huv hauv nroog yog tsim los ntawm kev ua haujlwm ntawm cov chaw haujlwm xws li chav kuaj mob thiab kho mob, chav kho mob, thiab chav kho mob ceev.Cov pa phem tseem ceeb uas muaj nyob rau hauv cov dej phwj tuaj hauv nroog cov chaw noj qab haus huv yog cov kab mob (cov qe kab mob, cov kab mob pathogenic, cov kab mob, thiab lwm yam), cov organic teeb meem, ntab thiab tshem tawm cov khib nyiab, cov pa phem, thiab lwm yam. Tag nrho cov kab mob hauv cov dej phwj uas tsis kho cov dej tsis huv mus txog 10. ^ 8/mlPiv nrog rau cov dej khib nyiab hauv kev lag luam, cov dej khib nyiab kho mob muaj cov yam ntxwv ntawm cov dej me me thiab muaj zog muaj kuab paug.
Cov Ntsiab Cai ntawm Kev Kho Dej DejNroj tsuag hauv Health Centers
Vim muaj zog viral xwm ntawm kev kho mob dej phwj tuaj, lub hauv paus ntsiab lus ntawmkho dej phwj hauv tsev kho mob cogyog cais qhov zoo thiab kev kho mob, cais thiab kho cov cheeb tsam hauv cheeb tsam, thiab tshem tawm cov pa phem ntawm cov chaw nyob ze.Cov kev kho mob tseem ceeb yog biochemistry thiab tshuaj tua kab mob.
Cov txheej txheem biochemical yog ib txoj kev sib cuag oxidation tau los ntawm txoj kev biofilm, uas suav nrog kev sau qee yam ntawm cov muab tub lim rau hauv cov khoom siv roj ntsha oxidation tank.Los ntawm kev siv cov biofilm txuas nrog cov muab tub lim thiab cov pa oxygen txaus, cov organic teeb meem hauv cov dej khib nyiab yog oxidized thiab decomposed los ntawm lom oxidation, ua tiav lub hom phiaj ntawm purification.
Lub hauv paus ntsiab lus ntawm kev kho mob yog txuas rau pem hauv ntej anaerobic seem thiab rear aerobic seem ua ke.Nyob rau hauv seem anaerobic, heterotrophic kab mob hydrolyze soluble organic teeb meem nyob rau hauv cov dej khib nyiab rau hauv cov organic acids, ua rau macromolecular organic teeb meem decompose rau hauv me me molecule organic teeb meem.Insoluble organic teeb meem hloov mus rau hauv cov organic teeb meem, thiab cov pa phem xws li cov proteins thiab cov rog yog ammonia (N ntawm cov saw organic lossis cov amino pawg hauv cov amino acids) kom dawb ammonia (NH3, NH4+).Muaj cov kab mob aerobic thiab cov kab mob autotrophic (cov kab mob digestive) nyob rau theem aerobic, qhov twg aerobic microorganisms decompose organic teeb meem rau hauv CO2 thiab H2O;Raws li cov pa oxygen txaus, cov nitrification ntawm cov kab mob autotrophic oxidizes NH3-N (NH4+) rau NO3-, uas yog xa rov qab mus rau ntu anoxic los ntawm reflux tswj.Nyob rau hauv cov xwm txheej anoxic, denitrification ntawm heterotrophic kab mob txo NO3- rau molecular nitrogen (N2), ua kom tiav lub voj voog ntawm C, N, thiab O hauv ecosystem, ua tiav kev kho dej phwj tsis muaj teeb meem.
