複合処理システムにおける難分解有機性廃液の高率処理に関する研究

探讨了上流式厌氧复合床(UAHB)反应器处理高硫化物、高氨氮发酵废水的颗粒形成过程和处理特性。结果表明，在处理含硫化物和氨氮废水的过程中可以形成颗粒，且没有发生硫化物对废水的抑制作用。因此，UAHB工艺对处理难降解废水具有较好的稳定性。试验结果表明，两级接触曝气工艺适合作为UABB废水深度处理工艺，因此认为UAHB+两级接触曝气组合工艺是处理高浓度硫化物和氨氮发酵废水的最佳工艺。以高浓度鱼油…生产废水为例，讨论了UASB反应器的启动和细菌结构分析更多的食品加工。启动结束后，在TOC负荷为10-12 kg-TOC/m~3/d的条件下，TOC的去除效率为60-70%，脂肪的去除效率为30-50%。污泥床上部颗粒几乎全部由类甲烷丝状细菌组成，下部颗粒呈多层细菌结构。在此基础上，建立了一套基本实用的去除鱼肉加工豆制品废水中的TOD和脂肪的工艺。照相废水中含有大量的有机和无机化学物质，不能仅用生物或化学方法处理。提出了三级处理系统，废水先进行生物处理，然后进行化学处理，将剩余的难降解化学物质转化为可生物降解的难降解物质，再进行生物处理。本研究将臭氧应用于化学反应阶段，并对该系统的去除效果进行了探讨。初步建立了一套基本实用的去除照相废水COD的工艺。较少

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
