Txhua ntawm plaub qhov kev kho dej khib nyiab loj tshaj plaws muaj nws tus kheej zoo, uas peb yuav qhia nyias hauv qab no;
Thawj yog MBR (Medium -Range Bioreactor), nrog rau cov txiaj ntsig hauv qab no: kev kho mob siab (turbidity < 1 NTU), me hneev taw (40% tsawg dua li cov txheej txheem activated sludge), qis sludge paug (txo 30-50%), thiab kev ua haujlwm ruaj khov (siab sludge concentration, resistant rau shocks);
The second is anaerobic ammonium oxidation (ANAO), which can be considered an upgraded version of the old-process nitrifying and denitrifying bacteria, and also incorporates the functions of hydrolytic acidifying bacteria to improve biodegradability and reduce carbon source addition. Its advantages include: no need for external carbon sources, low energy consumption (only about half of the ammonia nitrogen undergoes short-cut nitrification, 30-50% lower than AO), low sludge production (reduced by 60-70%), and some sludge can be sold. It also boasts a high ammonia nitrogen removal rate (>95%). Qhov thib peb yog granular sludge nyob rau hauv aerobic tej yam kev mob, nrog rau cov nram qab no technologies zoo: kev daws teeb meem zoo (tsav tshaj 30-50 m / h), me me hneev taw (txo 50%), ib txhij tshem tawm nitrogen thiab phosphorus, thiab txo nqi khiav hauj lwm (15% -25%).
Qhov thib plaub yog kev tswj xyuas dej ntse, nrog cov txiaj ntsig thev naus laus zis hauv qab no: tiag- lub sijhawm saib xyuas cov raj xa dej siab thiab ntws, qhov tseeb qhov chaw xau, AI optimization ntawm cov txheej txheem tsis, thiab cov cuab yeej digital ntxaib los simulate kev ua haujlwm.
Txhua tus txheej txheem, thaum muaj nws cov cuab yeej zoo, kuj muaj nws qhov tsis txaus. Wb kawm ua ke:
Ua ntej, cia peb rov qab mus rau MBR. Nws txoj kev loj hlob tsis muaj zog yog: tus nqi siab ntawm high - cov ntaub ntawv membrane kawg; kev xav tau ntawm kev tawg ntawm membrane fouling tswj tshuab; thiab cov nqi peev siab rau cov txheej txheem membrane (20% -30% siab dua li cov txheej txheem ib txwm muaj).
Txoj kev loj hlob tsis muaj zog ntawm anaerobic ammonia oxidation yog: ntev pib- lub sij hawm nce (ntau dua 90 hnub), kev ua haujlwm tsis zoo nyob rau hauv qis- qhov kub thiab txias (dab tsi txog lub caij ntuj no nyob rau sab qaum teb cheeb tsam?), complex reactor tsim thiab tswj kev ua haujlwm, thiab cov nqi txhawb nqa technology.
Lub bottlenecks nyob rau hauv txoj kev loj hlob ntawm aerobic granular sludge nyob rau hauv: tsis txaus cov txheej txheem stability, xav tau tej yam kev mob rau granular sludge tsim, rhiab heev rau cov dej zoo fluctuations, thiab tsis muaj kev paub nyob rau hauv kev txhawb technology.
Lub fwjchim luj kawg nkaus nyob rau hauv txoj kev loj hlob ntawm kev tswj dej ntse nyob rau hauv: cov ntaub ntawv hnyav silos (cov ntaub ntawv tsis sib koom ntawm cov tshuab sib txawv), kev siv nyiaj rov qab ntev (nruab nrab 3-5 xyoos), cov qauv kev tsis sib haum xeeb, thiab cov nyiaj txiag tseem ceeb ntawm cov lag luam me thiab nruab nrab.
