| Summary, etc. | As a result of increasing demand, intensive marine shrimp culture expanded rapidly in the 1970s. Intensive marine shrimp culture is aimed at the highest possible production from a given area to achieve maximum profit. Many problems arise from the production. Sediment is important environmental parameters in intensive marine shrimp culture, which produces approximately 16.2 million tons/year. Accumulated sediments from the Ranong shrimp ponds were generated at about 109 tons/ha/crop. Waste loading from sediment was substantial, with 7,436 kg COD/ha/crop, 2 kg N/ha/crop and 1 kg P/ha/crop. The sediments were extremely high in salinity, which having an ECe value of 50 dS/m and contained total solids of 271,970 mg/kg of sediment. Thus, disposal of sediment without treatment would lead to the salinization of soil and fresh water. The estimation of the biodegradable COD fraction in different F/M ratios showed that changes in the F/M ratio did not result in the change in the percentage of biodegradation. The change occurred in the shape of a curve, which lead to an inaccurate value. The suitable F /M ratio of sediment is between 0.3-0.6.Biodegradable COD fraction of sediment was obtained in the range 10%-28%. Regarding performance of the ae1obic fluidized bed reactor, the efficiency of COD removal could not be detected since sediment was mixed with seed sludge and could not separated. The problem with this experiment was a settling of sediment in the reactor. Thus, the estimation of oxygen consumption using the oxygen balance was calculated to quantify the COD concentration. The average oxygen uptake rate was 250 mg O/day. Anaerobic fluidized bed reactor was operated for about 38 days. Initially reactor was operated with synthetic feed and last with 80% synthetic and 20% sediments. About 3 L/day of gas generation was observed. The batch test anaerobic digestion of sediment was feasible in terms of waste stabilization. The stabilization of sediment resulted in 0.24-10.03% volume reduction, 1.6-20.99% overall VS reduction and 16.13-31.62 % COD reduction within 22 days. The percentage of COD reduction was comparable to the percentage of biodegradable COD p01tion from the respirometric method. |
