Results of treated Piggery Wastewater containing high organic matter and suspended solid by Anaerobic-Baffled-Reactor at the temperature of ambient(18℃-28℃) and mesophi1ic(33℃-37℃) range were follows: 1. Results of effluent pH, Alkalinity and Volatile Acid in reactor were 6.9-7.4, 4, 548㎎/1-6,812㎎/1, 255㎎/1-530㎎/1 Volatile acid/Alaklinity ratio was 0.037-0.107 and effluent Ammonia nitrogen concentration was 303㎎/1-688㎎/1. 2. COD removal rates and effluent COD concentration were 74.5% -54.3%, 1,607㎎/1-2,879㎎/1 in ambient temperature condition and 75.6-60.3%, 1537㎎/1-2501㎎/1 in mesophilic temperature condition according to COD loading rates from 0.5 to 8 Kg.COD/㎥. day 3. Each of total solid removal rates, effluent concentrations and volatile solid removal rates and effluent concentrations were 72.0%-53.0%, 1,200㎎/1-1, 988㎎/1, 70.6%-51.5%, 810㎎/1-1,374 mg/1 in ambient temperature condition and 72.2%-61.5%, 1,152㎎/1-1,630㎎/1, 73.3%-57.4%, 734㎎/1-1,208㎎/1 in mesophilic temperature condition according to COD loading rate from 0.5 to 8 Kg. COD/㎥.day 4. Gas production and methane contents were 0.8Liter/day-10.8Liter/day, 59%-46% in ambient temperature condition and 0.9Liter/day-13.2Liter/day, 63%-49% in mesophi1ic temperature condition according to COD loading rate from 0.5 to 8 Kg. COD/㎥. day and each of mathane gas production per 1g COD removal were 190cc-250cc, 230cc-300cc in ambient and mesophilic temperature condition.
