| Abstract | Pilot-scale aerobic-thermophilic process of night-soil,
septic tank sludge and pig-manure was carried out. This study was
in batch fed system. The highest temperature achieved with night-soil and septic tank sludge from Bangkok Metropolitan
Administration CBMA> was 45°C in 2 days detention. A removal of
COD, BOD, and VS were 14. 7%, 32. 2% and 15. 8% respectively, and
the oxygen uptake rate was 80 g02/Ckg VS. d) at the detention time
of 3 days.
For the pig- manure the initial BOD,/COD ratio was high of
the order of 0. 59 <which was more than that of night-soil which
was only 0. 27) . Because of more biodegradable organic matter, the
temperature raised as high as 55°C. The percentage removal of COD
and VS were 43% and 15. 93% respectively at the same detention
time.
The net energy of reactor for night - soil and pig-manure C2
days detention) was 441 . 7 MJ/d and 543. 6 MJ/d , respectively. The
sufficient high temperature can ensure the degree of inactivation
that would satisfy the health authorities. |
