Yuav kom ua tiav lub hom phiaj ntawm kev rhuav tshem cov pa phem hauv cov dej phwj tuaj, kev xaiv, kev cog qoob loo, thiab kev sib xyaw cov kab mob me me nrog lub peev xwm rhuav tshem tshwj xeeb ntawm cov dej phwj tuaj los tsim cov pab pawg kab mob thiab ua cov kab mob kho dej phwj tshwj xeeb yog ib qho ntawm cov txheej txheem siab tshaj plaws hauv kev siv tshuab kho dej phwj tuaj tam sim no.
Cov kab mob originateslos ntawm xwm, raug cog qoob loo thiab yug los ntawm kev dag, thiab thaum kawg rov qab mus rau xwm los ua lub luag haujlwm kho lub voj voog nitrogen ntawm cov dej, uas ua raws li cov ntsiab cai ntawm kev tsis muaj tshuaj lom, tsis muaj kuab paug, tsis muaj kuab paug thib ob, thiab tsis ua rau tib neeg lub cev tsis muaj teeb meem. Nws tuaj yeem tshem tawm ammonia nitrogen, BOD, COD, SS, nitrate, sulfate, chroma, tsw, cov tshuaj lom, cov tshuaj lom sib xyaw, thiab lwm yam, yam tsis tas yuav siv tshuaj coagulation thiab kev pab coagulation.
Nrog rau kev loj hlob ntawm tib neeg txoj kev lag luam hauv xyoo pua 21st, nws kuj tau ua rau muaj kev puas tsuaj loj heev thiab ua rau muaj kuab paug rau ib puag ncig thiab ua rau tib neeg txoj kev noj qab haus huv puas tsuaj loj heev. Yog li ntawd, kev tiv thaiv ib puag ncig los kho txhua yam kev ua qias tuaj yuav tshwm sim sai sai no. txoj cai tsom mus rau. Ntawm lawv, qib kev ua qias tuaj ntawm dej tau ua rau muaj kev tsis sib npaug ntawm ecological, thiab xwm tau poob nws lub peev xwm ntxuav nws tus kheej vim muaj kuab paug ntau dhau. Yog li ntawd, kev kho dej yog ib txoj hauv kev tseem ceeb los kho kom zoo dua qub ecology.
Ntawm ntau tuscov txheej txheem kho dej phwj tuaj, kev kho mob biological yog cov txheej txheem kho dej phwj tseem ceeb tshaj plaws hauv ntiaj teb vim nws cov txheej txheem yooj yim, cov txiaj ntsig zoo kawg nkaus, tus nqi qis, kev tiv thaiv ib puag ncig ntuj, thiab tsis muaj kev ua qias tuaj thib ob. Ntawm lawv, cov txheej txheem xws li biofilm txoj kev, biological trickle txoj kev, activated sludge txoj kev lossis ntxiv cov neeg sawv cev biological txhua tus siv lub peev xwm decomposition ntawm cov kab mob kom ua tiav lub hom phiaj ntawm kev ntxuav dej zoo. Txawm li cas los xij, feem ntau ntawm kev kho mob microbial tam sim no tsuas yog nyob ntawm kev ua ntawm cov kab mob spontaneous hauv cov dej khib nyiab sludge. Vim tias cov hom kev ua qias tuaj hauv cov dej phwj niaj hnub no yog qhov nyuaj heev, thiab cov hom kab mob biological uas decompose cov pa phem tsis tiav, qee qhov yuav tsum tsis muaj, tab sis cov tsis tsim nyog Nws yog ntau dhau, feem ntau vim tias tus lej ntawm cov kab mob zoo tsis txaus lossis lub peev xwm decomposition ntawm cov kab mob tsis txaus, thiab lub peev xwm los decomposition pa phem tsis zoo, yog li ntawd cov txiaj ntsig kho tsis yooj yim los tswj, thiab qee zaum nws yuav tsum cia siab rau hmoov zoo, yog li microbiologists tshwj xeeb hauv kev cog qoob loo microbial nrog kev puas tsuaj tshwj xeeb ntawm cov dej phwj rau qhov xwm txheej no.
Cov kab mob nitrifying:Cov kab mob nitrifying yog cov kab mob aerobic, suav nrog cov kab mob nitrifying thiab cov kab mob nitrifying. Kev nyob hauv dej aerobic lossis cov xuab zeb ua lub luag haujlwm tseem ceeb hauv cov txheej txheem nitrogen cycle dej purification. Nws muaj nyob rau txhua lub ces kaum ntawm xwm, suav nrog huab cua, dej ntws, hiav txwv, thiab av. Muaj ntau txhiab tus kab mob nitrifying pom muaj nyob rau hauv biology.
Cov kab mob denitrifying:Cov kab mob denitrifying yog cov kab mob uas ua rau denitrification. Feem ntau ntawm lawv yog cov kab mob heterotrophic thiab facultative anaerobic, xws li cov kab mob denitrifying, Staphylococcus spp. Nyob rau hauv lub xeev ntawm xenon, lawv siv cov pa oxygen hauv nitric acid los oxidize cov organic tshuaj kom tau txais lub zog xav tau rau lawv tus kheej cov haujlwm hauv lub neej. Cov kab mob denitrifying tau faib dav hauv av, quav tsiaj thiab dej phwj. Nitrate nitrogen tuaj yeem hloov pauv mus rau nitrogen roj es tsis yog ammonia nitrogen, uas tsis yog qhov sib txawv ntawm cov kab mob nitrifying. Nws yog siv rau hauv kev kho dej phwj, xws li kev kho dej toj roob hauv pes, kev kho dej hauv nroog, kev kho aquaculture, thiab lwm yam. Ntawm lawv, kev kho dej phwj aquaculture yog qhov siv dav tshaj plaws.
Cov kab mob sib xyaw ua ke nitrification thiab denitrification: cov kab mob sib xyaw ua ke nrog ob lub luag haujlwm ntawm nitrification thiab denitrification. Nyob rau hauv cov xwm txheej ntawm kev kho dej phwj tuaj yeem nyuaj dua, nws nyuaj dua los siv cov kab mob nitrifying lossis denitrifying ib leeg kom ua tiav qhov sib npaug ntawm cov kab mob. Qhov feem pua ntawm feem ntau cov tuam txhab tswj kev ua qias tuaj yeem tsis raug, ua rau muaj kev pov tseg lossis tsis txaus ntawm ntau cov kab mob, thiab nws nyuaj rau ua tiav qhov zoo tshaj plaws ntawm kev kho dej phwj tuaj yeem loj hlob raws li qhov zoo ntawm dej kom ua tiav qhov sib npaug ntawm cov kab mob, ua rau kev kho dej phwj ua haujlwm yooj yim dua thiab ua haujlwm tau zoo dua.
Cov thev naus laus zis kho dej phwj uas tsis muaj sludge daws qhov mob ntawm kev tso tawm sludge hauv cov txheej txheem kho dej phwj hauv ib qho kev sib tsoo.
Nrog kev tshem tawm BOD, COD, SS, ammonia nitrogen, phosphorus thiab lwm yam pa phem muaj zog heev, qhov txiaj ntsig zoo tshaj 90-95%. Cov dej khib nyiab los ntawm lub tank sedimentation theem ob tuaj yeem ua tau raws li lub teb chaws thawj chav kawm A lossis cov qauv zoo sib xws. Rau cov xim thiab cov xim thiab cov dej khib nyiab tiav thiab lwm yam dej khib nyiab uas nyuaj rau tshem tawm xim, nws tuaj yeem tshem tawm xim ncaj qha thaum muab tso rau hauv. Nws muaj cov nyhuv deodorizing zoo kawg nkaus, thiab muaj peev xwm tshem tawm NH3, P, H2S thiab cov organic acids.
Kev tsim tawm zoo heev thiab kev hloov pauv tau yooj yim, kev txhim kho noob caj noob ces, tuaj yeem daws tau qhov teeb meem ntawm cov dej phwj hauv lub neej yav tom ntej. Kev rhuav tshem cov tshuaj lom neeg tsim tawm xws li tshuaj tua kab, polychlorinated biphenyls, plasticizers, cov tshuaj ntxuav tes tsim tawm, thiab cov yas biosynthetic. Tiv thaiv cov kab mob, cov kab mob thiab cov kab mob parasitic. Tiv thaiv algae tsim tawm, ntxuav cov dej thiab xim dej. Tshem tawm cov hlau hnyav hauv cov dej phwj hauv tsev, xws li zinc, manganese, hlau, chromium ... thiab lwm yam.Cov kab mob kho dej phwj tuajyooj yim rau kev cog qoob loo, tsim tawm sai sai, muaj kev hloov pauv zoo rau ib puag ncig thiab kev hloov pauv ntuj. Thaum cov tshuaj lom neeg tshiab tshwm sim, lawv kuj tuaj yeem maj mam tsim cov enzymes tshiab los ntawm kev tshwm sim lossis kev tshoov siab, nrog rau kev ua haujlwm tshiab. muaj nuj nqi los rhuav tshem lossis hloov cov tshuaj tshiab.
