Lub taub dej Aeration yog qhov sib txuas ntawm dej pheeb suab thiab tshem tawm cov kev kho mob hauv qab, thiab cov khoom siv Athomal yog qhov nyuaj tshaj plaws ntawm tag nrho cov khoom siv biochemical tag nrho thiab txawm tias tus tag nrho cov txheej txheem los tswj . nws yog ib qho tseem ceeb heev kom tswj lub xeev ib txwm muaj ntawm lub tank tank {}}
{{01. pom kev ntawm scum teeb meem nyob rau saum npoo ntawm lub ARerer tank
Ua ntej tshaj plaws, nyob rau hauv lub Aperation Tank, vim tias muaj ib txwm muaj kev ua haujlwm qeeb, nws yog qhov nyuaj los tsim cov khoom tsis tsim nyog, thiab muaj ib qho teeb meem loj heev ntawm anaerobic {{1} raws li cov Kev ua kom pom tseeb, scum muaj xws li ua npuas dej, cov yeeb yaj kiab roj, muaj cov xim tsis sib xws, thiab lwm yam xws li xim dawb, xim av lossis dub, thiab txawv teb chaws.
Thawj hom yog ua npuas ncauj scum: feem ntau dawb, xim av xim av lossis xim tawv xim xim av lossis ua npuas dej dub, yuav nrog cov nplaum kom zoo nkauj lossis ntxhiab tsw;
Qhov thib ob hom yog roj zaj duab xis scum: feem ntau muaj oily factive zaj duab xis ntawm cov dej saum npoo av, qhov tshwm sim no feem ntau cuam tshuam nrog cov nyhuv nyoos thiab pretreatment nyhuv;
Qhov thib peb yog biofilm fragment scum: feem ntau zoo me ntsis xim av lossis grey flocculent txwv tsis pub muaj teeb meem, tej zaum yuav tshwm sim los ntawm sludge aging lossis ntau dhau kev;
Lub hom plaub yog tshuaj Scum: feem ntau hnov zoo li colloidal ntab teeb meem, feem ntau yog tshwm sim los ntawm ntau qhov kev hloov pauv hauv dej zoo .
Thib tsib hom yog muab sib xyaw cov txheej txheem: cov khoom sib xyaw ua ke ntawm cov kab mob uas tsis txaus ntseeg yuav tam sim no qhia txog qhov loj-teev kev luam tawm ntawm cov kab mob filamentous ntawm filamentous kab mob .

Ua ntej, peb tshuaj xyuas qhov ncaj qha rau cov scum los ntawm lub zog ntawm lub zog ua kua, yog li cov scumly lub zog ntawm cov kua ua kua. hauv kev ua si, peb pom qhov sib txawv ntawm cov scum thiab cov hmoov nplej sib xyaw hauv lub tank tank {}} Cov npuas no yog qhov chaw ua rau muaj kev sib xyaw ua ke, thiab nws yog qhov tsis muaj peev xwm ua kom loj npuas . qhov ua rau ntawm cov bubbles me me no, nws tseem yog qhov teeb meem tseem ceeb yog tias cov kev ua haujlwm ntawm cov tshuaj zais ntawm cov tshuaj txhuam ntawm cov tshuaj tiv thaiv kab mob sludge yog ntau dhau, lub viscosity ntawm sludge yuav nce siab heev, thiab vim tias qhov kev sib tsoo ntawm cov nqaij me me, thiab vim tias cov khoom siv me me, ntxiv rau cov khoom siv ntawm lub cev, cov khoom me me yog Feem ntau tso cov pa roj carbon dioxide thiab hydrogen los ntawm kev ua haujlwm sludge thaum muaj teeb meem carbon ntau ntxiv los ntawm cov hauv paus ua rau ntawm cov teeb meem ntawm scum teeb meem ntawm lub aeration tank .}} Thaum tshuaj ntsuam xyuas cov laj thawj tshwj xeeb, peb tuaj yeem tiv thaiv cov khoom lag luam microbial, thiab tshuaj lom neeg.
Microbial yam: yog tias nws yog daj-xim av zoo scum, cov tub rog hauv cov kab mob me me uas peb tuaj yeem ua rau cov kab mob microbient thiab cov pob zeb me me uas yuav ua rau scum {}}
Cov kev khiav hauj lwm tsis muaj zog: yog tias cov scum yog xim dub thiab xau yog qhov loj me ntsis, nws feem ntau tshwm sim los ntawm hydroge merry, thiab}} sludge hnub nyoog kuj yog qhov teeb meem uas yuav tsum tau ua txiav txim siab . Thaum lub caij nplooj zeeg muaj zog ntxiv, uas tseem ua rau muaj hnub nyoog zoo tshaj qhov kev hloov pauv ntawm SCUMTE { Cov dej tsis yeem, xws li roj, surfactants, thiab kev poob siab, uas yog cov khoom siv ntsuas kub xws li, ib puag ncig hloov pauv kuj tseem tuaj yeem muaj kev cuam tshuam .
3. Kev hloov kho kev hloov kho thiab cov tswv yim teb rau cov teeb meem scum ntawm cov kua hauv lub taub dej
Ua ntej, sim kom paub meej tias kev tswj kom meej ntawm cov txheej txheem Aererchen (SRT) Age) Pem hauv ntej-kawg dej inlet soj ntsuam. Yog tias muaj cov txiaj ntsig ntawm lub cev thiab tshuaj lom neeg yuav tsum tau muab cov khoom noj muaj txiaj ntsig thiab tshuaj lom neeg nkag mus rau cov khoom siv hauv qab System . Yog tias cov khoom siv tsis zoo, thiab tswj tau cov khoom noj kom zoo nkauj, thiab tswj tau cov khoom noj kom zoo dua, thiab tswj tau cov khoom noj kom zoo nkauj thiab daws cov teeb meem . Nyob rau hauv ntxiv rau kev tswj hwm txhua lub lim tiam, thiab saib xyuas cov ntawv me me ntawm cov kab mob nplua mias ntawm filamentous kab mob (tswj hwm<10%).
