外文摘要：A new method of hydrolytic acidification-sequencing batch reactor (SBR) process in aquatic products processing wastewater treatment is given. In the stage of the pretreatment, the hydrolysis-acidification technology was adopted, it is effective to improve the biodegradability of the wastewater. The SBR method was used in the stage of biochemical treatment. The experimental results show that the quality of aquatic products processing wastewater can attain to the national requirements of the first grade of integrated wastewater discharge standard (GB 8978 - 1996). When wastewater temperature was 20 degrees C, HRT was over 6 h and influent COD, BOD, and SS was 1100-1650 mg/L, 500-750 mg/L and 250-400 mg/L respectively, with more 95%, 96% and 92% of average removal rate respectively, the average effluent COD, BOD5 and SS was 55.5 mg/L, 19.8 mg/L and 20.0 mg/L. The largest organic loading was 4.1 kg COD/m(3) d. The BOD5/COD value of aquatic product processing wastewater can be raised from 0.50 to 0.64 via hydrolytic acidification treatment.
