- 論文の詳細を見る
Research was conducted on a channel flow wastewater treatment system which uses a natural hydraulic head and incorporates Tilapia and Pak-Bung for the simultaneous removal of TOC, T-N and T-P. Treatment of diluted synthetic wastewater and synthetic night soil resulted in mean TOC, T-N and T-P removal of more than 90%, 14-43E% and 7-58%, respectively, with a retention time of 2.8 days. Under optimum conditions, the crop yield of Pak-Bung was maintained at 1.5 kg/week/3.15 m^2 and the harvested Pak-Bung contained abundant vital amino acids and vitamins. Tilapia showed satisfactory growth in water channels without feeding at temperatures of 23.5℃ and higher with net-type contact materials. These results emphasized the benefit of channel flow treatment with Pak-Bung and Tilapia for simultaneous advanced wastewater treatment and food productioin.
