Microbial kev kho mob ntawm cov dej phwj vov yog kom muab cov roj microbial zoo ntawm lub cev muaj zog hauv lub cev nws tus kheej, nyob rau hauv uas tsis muaj cov decomposters, cov neeg tsim khoom, cov neeg tsim khoom lag luam, thiab cov neeg lag luam. Cov pa phem tuaj yeem kho tau thiab siv ntau cov khoom noj khoom haus tuaj yeem tsim tau, tsim cov zaub mov criss-hla kev lag luam lub vev xaib. Ib qho zoo thiab ruaj khov ecological sib npaug cov txheej txheem tuaj yeem tsim tau yog tias cov kev ntsuas kom tsim nyog thiab muaj peev xwm tswj hwm ntawm cov qib trophic. Thaum twg ib qho kev pheej hmoo ntawm cov dej phwj tuaj rau orgosystem, cov khoom muaj kuab paug ntawm lawv, yog siv los ua cov khoom siv roj carbon monantic, tab sis cov khoom siv hluav taws xob, tab sis cov khoom siv hluav taws xob, tab sis cov khoom siv hluav taws xob, thiab cov khoom siv roj carbon ntau, cov khoom siv nitrogen thiab phosphorus chaw, Thiab hnub ci zog yog siv los ua thawj lub zog. , koom rau hauv cov txheej txheem metabolic hauv cov vev xaib zaub mov, thiab thaum kawg hloov mus rau cov khoom lag luam muaj dej, thiab lwm yam khoom lag luam zoo nkauj, thiab los ntawm tib neeg Kev ua lag luam txuas ntxiv mus thiab ntxiv cov kev ntsuas kom tswj tau cov dej hauv lub cev sib npaug, nce kev zoo nkauj thiab xwm ntawm cov dej ntws, thiab ua tiav lub hom phiaj tiv thaiv thiab tswj hwm tus Eutrophication ntawm lub cev dej.
1. Microbial kho cov dej phwj tuajFeem ntau tsuas yog tshem tawm cov pa orgeic (Bod, cov khoom siv colloidal) hauv cov pa roj hmab thiab cov tshuaj tshem tawm tuaj yeem ncav cuag cov kuab paug organic tuaj yeem ntsib cov qauv kev tshem tawm.
(1) bod (biochemical oxygen xav tau), uas yog "biochemical oxygen thov" lossis "ntsuas ntsuas pa oxygen", yog ib qho ntsuas pom ntawm cov ntsiab lus hauv dej. Nws feem ntau yog hais txog ib feem ntawm yooj yim oxidizable organic muaj teeb meem muaj nyob rau hauv 1l ntawm dej phwj lossis dej ua piv txwv. Thaum microorganisms oxidize thiab diam oxygen nyob rau hauv cov dej haus hauv milligrams (chav nyob yog mg / l). Kev ntsuas cov kev ntsuas ntawm lub cev feem ntau yog cov cai ntawm 20 ° C rau 5 hnub thiab hmo ntuj, yog li lub cim bod5 feem ntau siv.
(2) COD (Cov tshuaj oxygen) yog qhov xav tau tshuaj lom neeg, uas yog qhov yooj yim indicectator ntawm cov ntsiab lus ntawm cov organic teeb meem hauv lub cev dej. (Chav yog mg / l). Feem ntau siv cov tshuaj oxidants yog k2cr2o7 lossis kmno4. Ntawm lawv, K2CR2O7 feem ntau siv, thiab ntsuas cov ntsuas yog sawv cev los ntawm "Cod Cr".
2. Microbial kho cov dej phwj tuaj tuaj yeem faib ua Aerobic kev kho mob thiab kev kho mob anaerobic raws li lub xeev ntawm cov pa oxygen hauv cov txheej txheem kev kho mob.
1. AEROBIC Kev Kho Mob
Nyob rau hauv aerobic tej yam kev mob, microorganisms adsorb cov teeb meem hauv ib puag ncig, purify, thiab synthesize cov teeb meem ntawm tib lub sijhawm. Nyob rau hauv cov txheej txheem ntawm dej lim, muaj cov kab mob muaj nyob rau hauv daim ntawv ntawm activated sludge thiab lub ntsiab ntawm biofilm.
2. Biofilm hom
Txoj kev no yog kev kho mob roj ntsha nrog rau biofilm raws li lub cev tseem ceeb ntawm lub cev. Biofilm yog cov mucous membrane uas txuas rau saum npoo ntawm cov cab kuj thiab feem ntau tsim los ntawm cov kab mob micelles. Txoj haujlwm ntawm biofilm yog tib yam li ntawm kev ua kom zoo nkauj hauv cov txheej txheem sludge, thiab nws cov microbial muaj pes tsawg leeg kuj zoo sib xws. Lub hauv paus ntsiab lus tseem ceeb ntawm cov dej phwj tuaj yog cov adsorption thiab oxidative decomposition ntawm cov organic teeb meem hauv cov cab hauv qab ntawm cov cab kuj. Raws li kev sib ze sib txawv ntawm nruab nrab thiab dej, tus qauv biofermm suav nrog cov qauv muaj xyoob ntoo xws li txoj kev lim roj ntsha.
Nyob rau hauv anoxic tej yam kev mob, tus qauv ntawm kev siv cov kab mob anaerobic (suav nrog cov kab mob uas muaj kev sib xyaw ua ke hauv qab zib kuj tseem hu ua anaerobic kev zom lossis kev ua haujlwm ntawm anaerobic lossis anaerobic fermentation. Vim tias cov khoom fermentation ua cov methohane, nws tseem hu ua methane fermentation. Hom no tsis tuaj yeem tsuas yog tshem tawm cov pa phem ib puag ncig, tab sis kuj tseem txhim kho bio-zog, yog li tib neeg them nyiaj ntau. Anaerobic fermentation ntawm cov dej phwj yog ib qho nyuaj heev rau cov kab mob, txhua tus yuav tsum muaj ntau yam sib txawv ntawm cov kab sib txawv. Methane Fermentation Xws li peb theem: liquefaction theem, hydrogen ntau lawm thiab acetic Acid ntau theem thiab metrhal ntau lawm theem.
Dej phwj tuaj yeem muab faib ua cov thawj coj, kev kho mob theem nrab thiab kev kho mob ntawm Tertiary raws li kev kho mob.
Kev Kho Mob Lub Npe: Nws feem ntau tshem tawm cov kuab paug rau hauv dej phwj hauv dej phwj hauv dej phwj hauv, thiab feem ntau ntawm lub cev kev kho mob tsuas yog ua tiav cov kev xav tau ntawm kev kho thawj zaug. Tom qab thawj zaug kho mob ntawm dej phwj tuaj, lub cev feem ntau tau raug tshem tawm los ntawm 30%, uas tsis tau raws li cov qauv tso tawm. Thawj txoj kev kho mob yog rau lub preprocessing ntawm kev kho mob ob.
Tus Txheej Txheem Kev Kho Mob yog: Qhov dej phwj nyoos uas tau dhau los ntawm cov kab sib chaws ntawm cov dej phwj Tank, cov saum toj no yog: kev ua thawj zaug (piv txwv li kev ua haujlwm ntawm lub cev). Txoj haujlwm ntawm cov grit Chamber yog tshem tawm inorganic hais nrog ib lub zog loj me me. Feem ntau yog siv cov pob zeb tsim kev sib tw ua tiav cov pob zeb, ib qho kev lag luam grit
Kev kho mob theem ob: nws tsuas yog tshem tawm cov kuab paug colloidal thiab yaj, yog li cov organic paug tuaj yeem ntsib cov qauv kev tshem tawm.
Cov txheej txheem kev kho mob theem ob yog: Cov dej ntws tawm ntawm thawj cov cuab yeej siv roj ntsha Kev Siv Hluav Taws Xob Tank, Kev Sib Tham Txog Hluav Taws Xob Kev Lom Zem Zoo, cov dej ntws tawm), dej ntws tawm ntawm cov cuab yeej siv roj ntsha nkag mus rau theem ob Tas tawm tank, thiab effluent los ntawm theem nrab kev ua kom tiav lub tees kom tso tawm tom qab kev tua kab mob lossis nkag rau hauv kev kho mob.
TERTIARY Kev Kho Mob: Feem ntau nrog refractory teeb meem, soluble inorganic teeb meem xws li nitrogen thiab phosphorus uas tuaj yeem ua
rau eutrophication ntawm dej lub cev. Cov hau kev siv suav nrog kev tshem tawm cov roj ntsha thiab phosphorus tshem tawm, txheej txheem xuab zeb, ua haujlwm rau cov qauv xuab zeb, ion sib pauv qauv.
Cov txheej txheem kho kev kho mob yog raws li hauv qab no: ib feem ntawm sludge nyob rau hauv theem nrab detimeration tank lossis basaling tu tank dowening tank. Tom qab dewatering thiab cov khoom siv kom qhuav, sludge yog thaum kawg siv.
Seb nws yog tus neeg yuav khoom tshiab lossis tus neeg yuav khoom qub, peb ntseeg tias cov kab mob tsis txaus ntseeg, peb tos txais cov neeg siv khoom tshiab thiab cov laus los tiv tauj peb los ntawm xov tooj ntawm tes lossis Xa Email los nug peb kom tsim cov koom haum ntev ntev thiab sib koom ua ke.
Cov Tshuaj Lom Kho MobTuam Tshoj cov kab mob tshwj xeeb tsim, muaj kev kawm ntawv zoo, cov neeg ua haujlwm zoo dua tshiab, peb tau ua haujlwm ntawm txhua cov kev tshawb fawb, kev tsim khoom, kev muag khoom thiab faib khoom thiab xa khoom. Los ntawm kev tshawb fawb thiab tsim cov thev naus laus zis tshiab, peb tsis yog ua raws li tab sis ua kev lag luam zam. Peb ua tib zoo mloog cov neeg siv khoom tawm tswv yim thiab muab kev sib txuas lus tam sim ntawd. Koj yuav hnov peb cov kev txawj ntse thiab saib xyuas kev ua tib zoo.
