Sludge yog ib qho khoom siv ib nrab lossis khoom siv thaum muaj kev cawm dim. Nws yog ib lub cev tsis tshua muaj neeg muaj cov khib nyiab, nws feem ntau yuav muab faib ua cov dej phwj tuaj, thiab lwm yam.
Tsis txhob ua rau sludge. Cov ntaub ntawv muaj feem tshwm qhia uas Suav sludge ntau lawm hauv 2020 yog qhov siab li 72.883 lab tons thiab muaj sludge yog 37.10 lab tons. Cov sludges no tsis zoo heev "zoo nkauj", hnov ntxhiab peculiar, thiab muaj qee cov co hnyuv. Yog tias lawv tsis kho, lawv yuav ua mob rau ib puag ncig thiab tib neeg kev noj qab haus huv. Txawm li cas los xij, Tuam Tshoj tau thov cov txheej txheem kev ua haujlwm ntawm "Kev siv cov peev txheej, tsis muaj kev phom sij thiab txo" li nruab nrab ntawm kev kho mob nruab nrab yog tseem tab tom tsim cov. Nyob rau tam sim no, Tuam Tshoj lub nroog loj hauv sludge kev kho tshuab feem ntau yog suav nrog cov khib nyiab, aerobic fermentation, incineration thiab lwm txoj hauv kev.
Cov av ntim cov av uas yuav tsum muaj cov peev txheej tsawg dua, cov txiaj ntsig sai, tus nqi qis thiab kev ua haujlwm yooj yim.
Aerobic fermentation yog kev siv cov kab mob aerobic thermophilic kom tsim cov khoom siv zoo li cov khoom siv kom zoo sib xws nrog cov av hauv av, yog li ntawd sludge tuaj yeem rov ua haujlwm dua.
Anaerobic kev zom yog cov kev zom zaub mov uas tso cai rau cov kab mob muaj teeb meem hauv qab ntawm cov kab mob allairia thiab cov kab mob anaerobic. Nws tuaj yeem kho sludge nrog cov ntsiab lus organic siab.
Kev siv tshuab thev naus laus zis yog siv lub tshuab hluav taws xob kom sov thiab qhuav lub cev kub kom zoo li cas rau hauv sludge mus rau hauv lub sludge mus rau hauv qhov chaw me me ntawm cov hmoov tshauv. Muaj ntau lwm txoj hauv kev rau sludge incineration, xws li siv cov thoob khib nyiab, siv cov chaw ua kom sov, siv thermal Coal-phia fais fab nroj tsuag, thiab hlawv sludge ib leeg. Txoj kev kho kev kho mob nrog kev ua siab loj raws li cov tub ntxhais tau pom tseeb zoo xws li txo qis kev txo qis thiab kev kho mob. Nws tuaj yeem ua rau txhua cov organic organic thiab txo cov sludge ntim (70% txo qis, nce mus txog 90% ntawm feem ntau). Nyob rau tib lub sijhawm, nws tuaj yeem hloov lub zog hauv cov sludge lub zog lossis thermal zog, tig cov khib nyiab mus rau cov khoom muaj nqis thiab kev siv cov sludge.
