Ua hauj lwm hauv kev kho cov dej phwj tuaj, yog tias koj paub yuav ua li cas soj ntsuam cov kab mob lom neeg, koj yuav tsum yog tus neeg sib tw zoo!
Nws paub zoo tias cov cuab yeej kho dej yuav tsum tau ua haujlwm thiab tu. Txwv tsis pub, leej twg paub yog tias lub twj tso kua mis rov qab yuav poob sai sai thiab txau av nkos thoob plaws lub ntsej muag ntawm tus thawj coj uas tuaj xyuas. . . .
Dab tsi yog qhov nyuaj rau kev khiav lag luam tshaj li cov khoom siv yog cov sludge. Hauv kev nkag siab, nws tuaj yeem hais tau tias txoj haujlwm tseem ceeb ntawm kev ua haujlwm hauv cov dej phwj tuaj yog kev sib ntaus sib tua wits thiab ua siab loj nrog cov sludge. Yog tias kev ua haujlwm tsis zoo, nws yog qhov yooj yim los ntsib qhov xwm txheej no - cov sludge tseem muaj sia nyob, tab sis koj ua lub neej phem dua kev tuag.

Txawm li cas los xij, qhov no tsuas yog qhov ntxeev ntawm lub iceberg. Tsis tas li ntawd, muaj MLSS, MLVSS, rov qab sludge concentration, sludge load, volumetric load, hydraulic retention time, sludge retention time, sludge age, etc.
Cov ntaub ntawv no txiav txim siab txog kev ua haujlwm macroscopic ntawm tag nrho cov dej kho, tab sis yog tias koj xav pom tias cov sludge loj hlob li cas, koj yuav tsum siv lwm txoj hauv kev - kev tshuaj xyuas microscopic.
Saib ncaj qha ntawm cov sludge nyob rau hauv lub microscope zoo ib yam li koj xav li cas thaum koj saib cov neeg txawv teb chaws.
Nyob rau hauv ib txwm sludge, nyob rau hauv ib lub microscope, koj tuaj yeem pom sessile ciliates daig rau cov sludge nyob txhua qhov chaw, xws li cov genera ntawm Campanula thiab Cladosporium, uas zoo li pawg ntawm cov nroj tsuag loj hlob tawm hauv av.
Yog hais tias lub kaw lus nyuam qhuav pib khiav, thaum lub sij hawm pib aeration, lub sludge kab mob floc xeev tsis ruaj khov heev. Lub sijhawm no, koj tuaj yeem pom ib pawg ntawm cov plaub mosaics ua luam dej nyob hauv qab lub tshuab ntsuas. Cov no yog da dej ciliates, xws li Nephridia thiab Paramecium.
Yog tias tsis muaj aeration hauv lub tank aeration thiab cov tshuaj tiv thaiv anaerobic tshwm sim, ib pawg ntawm cov mosaic zoo nkauj, zoo li twisted-headworms nrog lawv lub caj dab twisted, tuaj yeem pom nyob rau hauv lub tshuab tsom.
Yog tias aeration ntau dhau thiab cov sludge daws qhov muaj peev xwm deteriorates, ntau yam tsis pom zoo saib amoebas thiab rotifers nrog lub taub hau zoo li lub log uas tuaj yeem tig tuaj yeem pom hauv lub tshuab tsom.
Yog hais tias qhov concentration ntawm cov organic teeb meem nyob rau hauv cov dej los yog tsawg dhau lawm, ntau Euplotes uas zoo li cw yuav pom nyob rau hauv lub microscope.
Yog tias koj tsis muaj hmoo txaus pom ntau tus chij uas zoo li tadpoles nrog tails swinging rov qab thiab tawm (feem ntau tsuas yog cov genera ntawm Bonyna thiab Trichomonas), ceev faj, vim qhov no qhia tias muaj teeb meem nrog kev ua haujlwm ntawm cov activated sludge.
Kuj tseem muaj qhov xwm txheej phem tshaj plaws, qhov twg koj lub zeem muag yog qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob Yog li ntawd, kev tshuaj xyuas microscopic tsis tu ncua yog tus cwj pwm zoo, uas yuav pab daws teeb meem thaum muaj teeb meem thaum ua haujlwm, thiab tseem tuaj yeem tiv thaiv teeb meem ua ntej lawv tshwm sim thaum tsis muaj teeb meem.
