| Research Abstract |
In this study, the formation process of granule and treatment characteristics were discussed in an Upflow Anaerobic Blanket Reactor (UASB) treating a fermentation process wastewater consisting of high sulfide and ammonia. The results indicated that the granules could be developed in the process for treating sulfide- and anmmonia-rich wastewater, and inhibition caused by sulfide was not occured. Therfore, the UASB process was shown a better stability for treating the refractory wastwater.
the experimental results indicated that 2-stage contact aeration process was suitable process as advanced wastewater treatment of treaed wastewater from UAS
B.Therefore, it was thought that the combination process of UASB and 2-stage contact aeration was optimum process of treating treating a fermentation process wastewater consisting of high sulfide and ammonia.
The start-up of UASB reactor and analyzes of bacterial structures were discussed by using high concentration soy wastewater from fish food process. When start-up was finished, 60-70% TOC removal efficiency, and 30-50% lipid removal efficiency were obtained under the TOC loading rate of 10-12kg-TOC/m3/day. Almost all of the granules in the upper part of sludge bed consisted of Methanothrix-like bacteria while the granules in the lower part presented multi-layr bacterial structllres. Consequently, The basic
and practical process for TOD and lipid removal from soy wastewater from fish food process was thought to be established.
