In this study, the formation process of granule and treatment characteristics were discussed in an Upflow Anaerobic Hybrid Blanket (UAHB) reactor 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 ammonia-rich wastewater, and inhibition caused by sulfide was not occurred. Therefore, the UAHB process was shown a better stability for treating the refractory wastewater. The experimental results indicated that 2-stage contact aeration process was suitable process as advanced wastewater treatment of treaed wastewater from UAHB.Therefore, it was thought that the combination process of UAHB 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 … More 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/m^3/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 structures. Consequently, The basic and practical process for TOD and lipid removal from soy wastewater from fish food process was thought to be established.Photographic wastewater bears high level of various organic and inorganic chemicals which can not be deducted to the extent permitted for disposal only with a biological or a chemical method. We proposed a three-stage treatment system ; the wastewater was treated biologically at first, then chemically to reform the remaining refractory chemicals biodegradable, and biologically again. In this study, ozone was applied to the chemical stage and the removal efficiency of the system was discussed. The basic and practical process for COD removal from photographic wastewater was thought to be established. Less

研究了UAHB反应器处理高硫高氨发酵废水中颗粒污泥的形成过程及处理特性。结果表明，在处理高含硫高氨氮废水的过程中，颗粒污泥能够得到很好的发展，且不会产生硫化物的抑制作用。因此，UAHB工艺处理难降解废水具有较好的稳定性。试验结果表明，两级接触曝气工艺是UAHB焦化废水深度处理的适宜工艺，认为UAHB与二级接触曝气组合工艺是处理高硫高氨发酵废水的最佳工艺，以高浓度酱油养殖废水为研究对象，探讨了UASB反应器的启动和细菌结构分析 ...更多信息 食品加工启动结束后，在TOC负荷为10- 12 kg-TOC/m^3/d的条件下，TOC去除率为60-70%，油脂去除率为30-50%。污泥床上部的颗粒几乎全部由甲烷蓟马类细菌组成，而下部的颗粒则呈现多层细菌结构。摄影废水中含有大量的有机和无机化学物质，仅用生物或化学方法处理是无法去除的。我们提出了一个三级处理系统;废水首先进行生物处理，然后进行化学改革剩余的难降解化学品，再进行生物处理。在本研究中，臭氧被应用于化学阶段，并讨论了系统的去除效率。初步建立了基本的、实用的照相废水COD去除工艺。少
