Kab mob
Cov kab mob muaj zog adaptability thiab loj hlob sai. Raws li cov kev xav tau sib txawv, cov kab mob tuaj yeem muab faib ua ob pawg: kab mob autotrophic thiab kab mob heterotrophic.
Cov kab mob autotrophic siv ntau yam inorganic tshuaj (CO2, HCO3-, NO3-, PO43-, thiab lwm yam) ua cov as-ham los hloov lawv mus rau hauv lwm yam inorganic tshuaj, tso tawm lub zog, thiab synthesize cell tshuaj. Lawv qhov chaw carbon, nitrogen qhov chaw, thiab phosphorus qhov chaw yog tag nrho cov inorganic.
Cov kab mob heterotrophic siv cov pa roj carbon monoxide los ua cov pa roj carbon monoxide thiab cov organic lossis inorganic nitrogen ua cov khoom siv nitrogen, hloov lawv mus rau hauv cov khoom siv tsis zoo xws li CO2, H2O, NO3-, CH4, NH3, tso tawm lub zog thiab ua kom cov khoom siv ntawm tes. Cov kab mob hauv cov dej phwj tuaj yog cov kab mob heterotrophic.
Fungi
Cov fungi muaj xws li pwm thiab poov xab. Fungi yog cov kab mob aerobic uas siv cov khoom organic ua cov pa roj carbon monoxide. Kev loj hlob pH yog 2-9 thiab qhov zoo tshaj pH yog 5.6. Fungi xav tau oxygen tsawg dua, tsuas yog ib nrab ntawm cov kab mob. Fungi feem ntau tshwm sim nyob rau hauv ib puag ncig uas tsis muaj pH thiab tsawg dua molecular oxygen.
Fungal mycelium plays lub luag haujlwm ntawm lub cev pob txha hauv coagulation ntawm activated sludge, tab sis cov tsos ntawm cov kab mob filamentous ntau dhau yuav cuam tshuam rau kev ua haujlwm ntawm cov sludge thiab ua rau sludge o. Lub luag haujlwm ntawm fungi hauv kev kho dej phwj tuaj yeem tsis quav ntsej.
Algae
Algae yog unicellular thiab multicellular nroj tsuag microorganisms. Nws muaj chlorophyll, siv cov photosynthesis los ua kom cov pa roj carbon dioxide thiab dej tso tawm oxygen, thiab nqus cov as-ham xws li nitrogen thiab phosphorus hauv dej los ua kom nws cov hlwb.
Protozoa
Protozoa yog cov tsiaj txhu qis tshaj plaws uas tuaj yeem faib thiab nthuav dav. Protozoa hauv dej phwj yog ob qho tib si dej purifiers thiab cov ntsuas dej zoo.
Feem ntau cov protozoa yog aerobic heterotrophic. Hauv kev kho cov dej phwj tuaj, lub luag haujlwm ntawm protozoa tsis tseem ceeb npaum li cov kab mob, tab sis vim tias feem ntau cov protozoa tuaj yeem noj cov khoom organic thiab cov kab mob dawb, lawv muaj cov txiaj ntsig zoo ntawm cov dej huv. Protozoa yog rhiab rau ib puag ncig kev hloov pauv, thiab cov protozoa sib txawv tshwm sim nyob rau hauv qhov sib txawv dej zoo ib puag ncig, yog li lawv yog cov ntsuas dej zoo. Piv txwv li, thaum yaj cov pa oxygen txaus, lub moos worms tshwm ntau, thiab thaum yaj cov pa oxygen tsawg dua 1㎎ / L, lawv tshwm tsawg dua thiab tsis ua haujlwm.
Metazoa
Metazoa yog cov tsiaj txhu ntau. Feem ntau cov metazoans hauv cov chaw kho dej phwj thiab cov pas dej stabilization muaj xws li rotifers, nematodes thiab crustaceans.
Metazoans yog txhua yam kab mob aerobic uas nyob hauv ib puag ncig zoo dej. Metazoans pub rau cov kab mob, protozoa, algae thiab organic solids. Lawv cov tsos qhia tau hais tias cov nyhuv kho tau zoo thiab lawv yog cov kab mob qhia txog kev kho dej phwj tuaj.
Cov kab mob sib kis
A. Paramecium
1. Kev faib tawm: tsis yog -activated sludge protozoa
2. Lub cev: ntev: 180-300 microns, dav: 42-75 microns
3. Morphology: Paramecium yog ib tug loj protozoan. Nws lub cev yog cylindrical, qhov dav tshaj plaws nyob rau hauv nruab nrab ntawm lub nraub qaum ib nrab, thiab muaj lub qhov ncauj concave zawj ntawm ventral sab ntawm lub hauv ntej ib nrab. Muaj ib lub qhov ncauj elliptical nyob rau hauv qab ntawm nruab nrab zawj. Lub cev yog sib npaug nrog cilia, thiab qee qhov cilia tom qab kawg yog me ntsis ntev; lub exoplasm nyob rau hauv daim nyias nyias yog cov pob tshab, lub endoplasm yog tag nrho ntawm granular tshuaj, muaj ntau npuas zaub mov, thiab muaj ob contractile npuas, ib tug nyob rau ntawm ib tug -quarters ntawm lub cev ntev thiab lwm yam nyob rau ntawm peb-quarters ntawm lub cev ntev.
4. Ecology: Nws tsuas yog pub rau cov kab mob, thiab qhov zoo tshaj plaws ecological ib puag ncig yog cov pa phem nruab nrab thiab ntau- pa phem. Nws tshwm nyob rau hauv ntau qhov chaw nyob rau hauv ib qho chaw uas yaj cov pa concentration yuav luag undetectable. Nws tshwm sim ntau zaus hauv activated sludge thaum purification theem tsis zoo.
B,-mob ncauj plab
1. Kev faib tawm: activated sludge protozoa
2. Lub cev: ntev: 32-70 microns, dav: 22-48 microns, lub qhov ncauj txoj kab uas hla: 12-25 microns, kov ntev: 20-380 microns
3. Morphology: Lub cev yog kwv yees li ncig, tab sis nws qhov ntev feem ntau tseem ntev dua nws qhov dav. Lub qhov ncauj yog me me thiab nqaim nyob rau hauv pem hauv ntej, thiab widest nyob rau hauv nruab nrab ib feem. Nws maj mam tapers ntawm nruab nrab mus rau pem hauv ntej thiab nram qab kawg. Lub qhov ncauj ciliated yog me ntsis me dua lub qhov ncauj. Lub endoplasm yog mis nyuj dawb los yog lub teeb xim av, feem ntau muaj ntau cov khoom noj vacuoles. Tus kov yog qhov sib luag, thiab muaj myofilament sheath hauv tus kov, uas yuav ncab thiab thim rov qab thaum txhawb nqa. Nws feem ntau nyob ib leeg thiab tsis tshua muaj tus cwj pwm ntawm pawg. Lub cev ua luam dej yog slender thiab cylindrical, thiab txav ceev ceev.
4. Ecology: Nws pub tsuas yog cov kab mob, thiab kuj preys ntawm microscopic ib leeg -cell algae. Qhov zoo tshaj plaws kub rau nws yog 25 degree. Yog tias qhov kub siab tshaj 35 degree, nws yuav tsim ib lub tshuaj ntsiav lossis deformity, thiab thaum kawg tuag. Nws tshwm sim ntau thaum cov dej tsis zoo, thiab BOD feem ntau qis dua 20mg / L.
C. Phaj plhaub kab
1. Kev faib tawm: activated sludge protozoa
2. Lub cev: Ntev: 55-65 microns, dav: 28-32 microns
3. Morphology: Lub cev yog chim -zoo li tus thiab grenade- zoo li tus, me ntsis o nyob rau hauv nruab nrab, thiab qhov ratio ntawm lub cev ntev mus rau lub cev dav yog li ntawm 2 mus rau 1. Lub morphology yog tsau thiab ntau los yog tsawg xim av; Lub plhaub phaj tsim los ntawm ectoplasm muaj 15-20 kab, thiab lub plhaub phaj tau muab faib ua rau ntu los ntawm kev sib hloov grooves, txhua ntu tsim ib daim ntawv thiab tus naj npawb ntawm "qhov rais panes". Cilia sib npaug thoob plaws lub cev, thiab lub qhov ncauj ntawm tes yog nyob rau hauv pem hauv ntej kawg, uas yog ib puag ncig ntawm cilia thiab tsis yooj yim pom.
4. Ecology: Plate plhaub kab tuaj yeem tua ntawm algae, flagellates me, thiab ciliates me me, thiab tseem nqus cov rotifers tuag. Lawv feem ntau tshwm sim thaum BOD load tsawg, cov pa oxygen concentration siab, thiab BOD ntawm cov dej kho tau tsawg.
