Key Points For Daily Operation And Maintenance UASB Anaerobic Tank

Kev Saib Xyuas Dej Zoo: Tshawb xyuas COD, pH, thiab kub tsawg kawg ib zaug ib hnub; effluent COD, VFA, ALK, thiab SV30 (qhov sib piv yuav tsum yog<20%).

Sludge Management:
Saib xyuas qhov siab ntawm sludge txaj. Yog tias nws siab tshaj 1/2 ntawm lub tank qhov siab, ntws qee cov sludge kom tsim nyog;
Sludge draining zaus: Tshem tawm 5% -10% ntawm cov sludge txaj ntim txhua lub lim tiam kom tiv thaiv kev laus.

Khoom siv tu:
Tsis tu ncua ntxuav cov khib nyiab los ntawm cov dej ntws tawm (yuav tsum ceev faj kom tsis txhob poob);
Xyuas cov dej theem ntawm cov dej - lub tank foob thiab tswj qhov siab li qub;
Calibrate cov cuab yeej xws li pH ntsuas, ntsuas kub, thiab ntsuas ntsuas.

Biogas System:
Hydrogen sulfide cov ntsiab lus hauv biogas yuav tsum yog<20 mg/m³ and requires desulfurization treatment;
Ntxuav cov pa roj-kua kua cais txhua hli thiab xyuas qhov ua tau zoo ntawm desulfurizer peb lub hlis twg.

UASB (Upflow Anaerobic Sludge Blanket) anaerobic tank yog cov cuab yeej tseem ceeb rau kev kho kom zoo siab -concentration organic wastewater. Nws txoj haujlwm ruaj khov nyob ntawm kev tswj cov txheej txheem meej, cov txheej txheem kev ua haujlwm tau zoo, thiab kev tswj hwm kev nyab xeeb nruj.
