Lub tshuab kho dej phwj hauv nroog zoo meej yuav tsum yog raws li cov pej xeem hauv zos, thaj chaw, kev lag luam thiab lwm yam rau kev txiav txim siab dav dav, xaiv cov khoom siv kho dej phwj tsim nyog thiab kev sib phim tsim nyog.
Grid yog thawj txheej txheem hauv cov txheej txheem kho dej phwj tuaj yeem siv los ntes cov khoom loj. Grating muaj peev xwm muab faib ua cov grating ntxhib thiab cov grating zoo, cov grating ntxhib feem ntau yog siv los ntes cov khoom loj dua, xws li nplooj, hnab yas, thiab lwm yam; cov grating zoo feem ntau yog siv los ntes cov khoom me me, xws li av nplaum, khib nyiab, thiab lwm yam.
Lub tank xuab zeb siv los tshem cov xuab zeb thiab cov khoom tsis muaj zog uas muaj lub zog tshwj xeeb loj hauv cov dej phwj tuaj. Lub tank xuab zeb feem ntau teeb tsa rau hauv lub tank sedimentation loj, dej phwj tuaj ntws los ntawm kev siv lub zog hnyav los ua kom cov khoom me me poob rau hauv.
Lub thawv tso dej phwj thawj zaug yog ib feem tseem ceeb ntawm lub tshuab kho dej phwj, siv los tshem tawm cov khoom seem thiab qee cov organic teeb meem hauv cov dej phwj. Lub thawv tso dej phwj thawj zaug yuav tso cov khoom seem rau hauv qab los ntawm kev tso dej phwj ntuj lossis khawb, thiab tom qab ntawd tso tawm los ntawm cov khoom siv tso dej phwj.
Lub tank tshuaj lom neeg yog lub hauv paus tseem ceeb ntawm cov dej khib nyiab kho thiab siv los rhuav tshem cov organic teeb meem thiab tshem tawm cov pa phem xws li ammonia, nitrogen thiab phosphorus. Ntau yam kab mob me me, suav nrog cov kab mob aerobic thiab cov kab mob anaerobic, feem ntau yog cog rau hauv bioreactor, thiab cov organic teeb meem raug hloov mus ua cov tshuaj tsis muaj teeb meem los ntawm kev ua haujlwm ntawm cov kab mob me me.
Lub tank sedimentation thib ob yog lub tank sedimentation tom qab lub bioreactor, uas yog siv los cais cov sludge activated hauv bioreactor ntawm cov dej kho. Lub tank sedimentation thib ob yog siv los khawb cov sludge activated mus rau thaj chaw sau sludge hauv nruab nrab los ntawm kev siv lub tshuab scraper lossis lub tshuab nqus, thiab tom qab ntawd cov sludge activated raug xa rov qab mus rau bioreactor los ntawm kev siv cov khoom siv sludge rov qab. Cov khoom siv tua kab mob yog siv los tua cov kab mob me me xws li cov kab mob thiab cov kab mob hauv cov dej phwj tuaj, thiab cov txheej txheem tua kab mob feem ntau yog chlorination disinfection thiab ozone disinfection.
Ntxiv rau cov khoom siv kho dej phwj tuaj saum toj no, muaj qee cov khoom siv pabcuam, xws li lub tshuab cua, cov khoom sib tov, cov twj tso kua mis thiab lwm yam. Cov khoom siv no ua lub luag haujlwm sib txawv hauv cov txheej txheem kho dej phwj, xws li muab cov pa oxygen, sib tov cov dej phwj, tsa cov dej phwj thiab lwm yam.
Thaum xaiv thiab phim cov khoom siv kho dej phwj tuaj, yuav tsum xav txog cov yam ntxwv thiab qhov xwm txheej tiag tiag ntawm lub nroog. Piv txwv li, rau thaj chaw uas muaj cov neeg tsawg thiab thaj chaw nyuaj, cov khoom siv kho dej phwj me me thiab modular tuaj yeem xaiv los pab txhawb kev thauj mus los thiab kev teeb tsa; rau thaj chaw uas muaj kev lag luam zoo dua, cov khoom siv uas muaj thev naus laus zis siab heev thiab kev kho kom zoo tuaj yeem xaiv. Tib lub sijhawm, cov yam xws li kev saib xyuas thiab cov nqi khiav lag luam ntawm cov khoom siv, nrog rau kev yooj yim ntawm kev ua haujlwm thiab kev ntseeg tau, yuav tsum tau xav txog.
Liding Environmental Protection tshwj xeeb hauv kev tsim khoom thiab kev txhim kho cov khoom siv kho dej phwj hauv nroog, nrog rau kev ua haujlwm tiag tiag ntawm qhov project, thiab muaj kev paub ntau hauv kev lag luam, uas cov khoom siv kho dej phwj sib xyaw ua ke muaj qee qib ntawm kev coj noj coj ua hauv kev lag luam.
