Kev paub nrog kua muag!
Peb txhua tus tau ua si ntawm kev ua si ntawm cov npuas npuas, cov npuas yog cov khawv koob thiab lom zem heev, tab sis muaj ib hom neeg uas tsis tuaj yeem zam cov npuas, thiab txawm tias tshem cov npuas yog ib feem ntawm lawv txoj haujlwm, thiab hom neeg no yog dej. Kev kho mob Kev Lag Luam thiab Kev Kho Mob.
Foaming nyob rau hauv lub aeration tank yog ib qho teeb meem tshwm sim hauv kev kho dej thiab kev kho. Thaum nws tshwm sim, nws tuaj yeem ua rau qee qhov tsis zoo:
1. cuam tshuam rau kev ua haujlwm ntawm cov twj paj nruag thiab ntsuas, uas yuav ua rau kev ua haujlwm tsis zoo ntawm cov txheej txheem rau kev tswj tsis siv neeg thiab ua rau muaj kev cuam tshuam ntawm cov txheej txheem.
2. Cov npuas dej nkag mus rau hauv lub tank thib ob thiab cuam tshuam rau qhov zoo ntawm cov effluent.
3. Rau cov txheej txheem ntawm kev siv cov cuab yeej aeration saum npoo, nws yuav tiv thaiv kom tsis txhob muaj qhov aeration thiab oxygenation, kom cov pa yaj hauv lub pas dej aerobic tsis txaus.
4. raug thuam los ntawm cov thawj coj, tshwj xeeb tshaj yog cov thawj coj uas tsis paub yuav ua li cas.
Thiab lwm yam……
Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tsum tau xyuam xim rau, nkag siab thiab muaj peev xwm daws tau qhov teeb meem ua npuas ncauj ntawm lub aeration tank.
01 Npauj Npaim tuaj qhov twg?
Nws tsis tau teem sijhawm, nws tau tawg.
Yuav kom nkag siab txog qhov teeb meem ntawm cov npuas dej hauv lub tank aeration, koj yuav tsum xub to taub nws txoj cai. Thawj tsab xov xwm ua ib qho piv txwv ntawm "blowing npuas", thiab lub hauv paus ntsiab lus ntawm foaming nyob rau hauv lub aeration tank yog tib yam li hais tias ntawm "blowing npuas". Muaj ob qhov zoo sib xws: ib qho yog tshuab cua; Lwm qhov yog cov dej raug cua tshuab muaj surfactants, suab thaj thiab lwm yam khoom.
Cov khoom xyaw uas siv los kho cov dej npuas feem ntau muaj xws li tshuaj ntxuav tes (xws li), qab zib, tshuaj yej, thiab lwm yam, uas txawv, tab sis yog ob hom tshuaj. Ib qho yog surfactants, xws li detergents, xab npum, thiab lwm yam Foaming nyhuv, qhov thib ob yog ua npuas ncauj stabilizer, xws li qab zib, tshuaj yej, thiab lwm yam, tuaj yeem txhim kho cov viscosity ntawm npuas, yooj yim rau cov duab, ruaj khov dua.
Cov dej npuas dej uas tau hais los saum toj no lossis cov khoom zoo sib xws yog ib qho yooj yim tshwm sim hauv cov dej phwj tuaj, xws li cov khoom siv saum npoo av, filamentous microorganisms, organic tshuaj, thiab lwm yam. Thaum cov tshuaj no tshwm sim, lawv yuav tshuab npuas hauv lub tank aeration.
02 Yuav Ua Li Cas Txiav Txim Siab Ua Npuas Ncauj?
Sib txawv ntawm cov npuas cua tshuab los ntawm lub tshuab npuas, cov npuas cua tshuab los ntawm lub aeration tank muaj cov yam ntxwv sib txawv vim nws cov complex muaj pes tsawg leeg. Yog li, cov ua npuas ncauj tuaj yeem txheeb xyuas thiab txiav txim raws li xim, duab, qhov loj me, thiab viscosity ntawm cov khoom sib xyaw, thiab cov pawg ntau tau teev tseg:
dawb, me me ua npuas ncauj
Cov lus piav qhia: Cov xim yog dawb, lub teeb thiab nyias, tawg nyob ib ncig ntawm lub aeration cheeb tsam, tsis ruaj tsis khov, yooj yim tawg, thiab lub sij hawm txij nkawm luv luv.
Kev txiav txim yog vim li cas: Nws yog ib qho yooj yim uas tshwm sim nyob rau hauv thawj theem ntawm aeration tank pib thiab denitrification tshwm sim nyob rau hauv cov cheeb tsam. Cov teeb meem ua npuas dej zoo li no yuav tsis cuam tshuam rau kev ua haujlwm ntawm cov txheej txheem thiab tsis tas yuav ntsuas kev kho mob.
khaki ua
Cov lus piav qhia: Cov nplaim ntawm cov npuas dej yog turbid thiab cov xim yog khaki, zoo ib yam li cov xim ntawm cov activated sludge, yooj yim rau tawg thiab tsis yooj yim rau sau.
Kev txiav txim ntawm qhov ua rau: cov sludge yog aging los yog yuav aging, thiab ib feem ntawm cov sludge disintegrates thiab dissipates nyob rau hauv dej, thiab tusyees adheres rau cov npuas dej nyob rau hauv lub aeration lub xeev, uas txhim khu kev ruaj ntseg ntawm cov npuas thiab ua rau lub phenomenon ntawm ua npuas ncauj.
grey-dub ua npuas ncauj
Cov lus piav qhia: Cov npuas dej sib sau nyob ib ncig ntawm pawg aeration, thiab lub cev dej yog grey-dub tag nrho, thiab nws tsis yooj yim rau sau.
Yog vim li cas kev txiav txim: anaerobic cheeb tsam tshwm sim nyob rau hauv lub aeration tank, ib feem ntawm cov activated sludge tuag thiab disintegrated, thiab adhered rau cov npuas generated los ntawm aeration, uas ua rau lub extension ntawm lub npuas bursting lub sij hawm thiab tiam ntawm grey-dub npuas.
03 Kev tiv thaiv
Tau ntsib nrog cov teeb meem ntawm cov npuas dej hauv lub tank aeration, ua ntej ntawm tag nrho cov, peb yuav tsum paub tias tsis tu ncua aeration nyob rau hauv lub pas dej ua ke ntawm cov dej uas muaj activated sludge thiab cov pa phem yuav inevitably tsim npuas, thiab feem ntau ntawm cov npuas nyob rau hauv aeration tank yog ib txwm thiab tsis tas yuav tsum tau. kho. , tus neeg yuav tsum tau tsom mus rau kev kho mob ntawm qhov teeb meem no tsis muaj dab tsi ntau tshaj li pib los ntawm peb yam ntawm influent dej zoo, activated sludge thiab aeration.
Qhov zoo ntawm cov dej muaj zog yog tsis muaj dab tsi ntau tshaj li tswj cov acidity thiab alkalinity, kub, nto active tshuaj, thiab lwm yam, thiab cov kev ua ntawm cov sludge yog tsis muaj dab tsi ntau tshaj li tswj qhov ratio ntawm cov zaub mov rau microbes, thiab ces tswj lub aeration, feem ntau. nyob rau hauv txoj kev aeration thiab aeration npaum li cas, uas yog lub hauv paus tswj kev ntsuas. , Kev ntsuas kub muaj xws li txau dej, ntxiv defoamer thiab lwm yam.
