Aeration nyob rau hauv cov txheej txheem activated sludge yog raws li kev tso cua rau hauv lub tank, uas txhawb kev loj hlob microbial hauv cov dej khib nyiab. … Tom qab nyob rau hauv ib lub tank cais, cov kab mob uas ua rau "activated sludge" flocks yog txuas ntxiv rov qab mus rau lub aeration phiab kom nce tus nqi decomposition.
Vim li cas cov sludge aerated Mcq?
Vim li cas cov sludge aerated? Nqe lus piav qhia: Lub tshuab ua kom muaj zog-sludge reactor yog lub kaw lus uas tau kho cov dej phwj ua ntej (piv txwv li tau dhau los ntawm kev kho thawj zaug) yog aerated los txhawb kev loj hlob ntawm cov kab mob (hlwb) uas maj mam haus cov organics hauv cov kav dej.
Lub hom phiaj ntawm kev ua kom aeration hauv cov txheej txheem sludge activated yog dab tsi?
Aeration yog txheej txheem sludge activated, txhawb nqa microbial kev loj hlob hauv cov dej khib nyiab. Cov microbes ces pub rau cov khoom siv organic, tsim cov tsiaj uas yooj yim tawm.
Sludge aerated yog dab tsi?
Activated sludge hais txog kab lis kev cai flocculent ntawm cov kab mob tsim hauv aeration tso tsheb hlau luam raws li kev tswj hwm, raws li WEF. Activated sludge feem ntau yog xim av xim. Activated sludge tseem hu ua khib nyiab qhib biosolids lossis khib nyiab qhib cov khib nyiab.
Lub hom phiaj ntawm kev siv aeration hauv kev kho dej khib nyiab yog dab tsi?
Hauv kev ua dej txias, ib lub hom phiaj tseem ceeb ntawm aeration yog kom tshem tawm cov pa roj carbon dioxide. Aeration kuj yog siv los oxidize soluble hlau thiab manganese(pom nyob rau hauv ntau qhov dej zoo) rau insoluble precipitates. Aeration feem ntau yog siv los txo cov pa roj carbon dioxide liberated los ntawm kev kho mob.

Sludge tsim li cas?
Primary sludge yog tsim los ntawm cov tshuaj nag lossis daus, sedimentation, thiab lwm yam txheej txheem tseem ceeb , whereas secondary sludge yog cov khoom siv pov tseg biomass uas tau los ntawm kev kho mob lom. Qee cov dej phwj tuaj dej phwj muaj peb txoj hauv kev kho mob lom neeg:
Thaum twg siv sludge?
Thaum kho, cov dej phwj tuaj yeem qhuav thiab ntxiv rau hauv qhov chaw pov tseg, siv rau ua liaj ua teb qoob loo ua chiv, lossis ntim nrog lwm cov ntaub ntawv thiab ua lag luam ua "biosolid compost" rau kev siv. hauv kev ua liaj ua teb thiab kev tsim vaj tse.
Vim li cas thiaj tsim nyog dewatering sludge?
Vim li cas thiaj yuav tsum tau dewatering? Ob lub hom phiaj tseem ceeb ntawm sludge dewatering yog rau pov tseg kom tsawg thiab ua tiav tag nrho cov nqi kev pov tseg. Tsis tas li ntawd, cov sludge ruaj khov tuaj yeem ua haujlwm tau zoo dua thiab tuaj yeem txo qis kev noj qab haus huv.
Aerated chocolate ua li cas?
Aerated chocolate, tseem hu ua cua chocolate, yog hom chocolate uas tau hloov mus ua npuas dej ntawm qhov sib ntxiv ntawm cov pa npuas. … Thaum lub sij hawm tsim cov kua chocolate loj yog foamed nrog ib tug propellant, thiab ces txias nyob rau hauv ib tug tsis tshua muaj siab ib puag ncig.
Koj puas tuaj yeem ua cov blocks aerated?
Qhov tsuas yog hais txog Thermalite cov blocks yog tias lawv tsim cov substrate mos heev thiab yog li ntawd tuaj yeem ua kom yuam kev. Qhov zoo tshaj plaws, Thermalite blocks xav tau kev ua tiav nrog cov khoom siv uas phim lawv hauv softness thiab saj zawg zog kom tsis txhob tawg.
