1. Establishment of biological treatments for marine dumping wastewater(1) A study of treating the refractory wastewater by combination process of UAHB and 2-stage contact aerationThe formation mechanism of granule and treatment characteristics were discussed in an Upflow Anaerobic Hybrid Blanket (UAHB) reactor treating fermentation wastewater consisting of high sulfide and ammonia. The results indicated that the granules could be developed in the process for treating sulfide- and a ammonia-rich wastwater, 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 also indicated that 2-stage contact aeration process was suitable as a post treatmen of UAHB.As the results, it could be conluded that the combination process of UAHB and 2-stage contact aeration was optimum system for treating a fermentation process wastewater consisting of high sulfide and ammonia.(2) A study of … More treating high salinity wastewater by 2-stage contact aeration process2-stage contact aeration process was used to treat sulfanilamide wastewater containing high salinity and high strength organic matter. The results indicated that sulfanilamide was able to treat by 2-stage contact aeration process, and the limitaton of loading rate was around 1.85 kg-TOC/m^3/day.(3) A study of treating photographic wastewater by three-stage treatment systemPhotographic 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 established.2. Evaluation for the effect of marine environment by marine dumping waste and wastewaterWe developed the Shallow Sea Ecological Model (SSEM) that focuses on living organisms, especially fish and benthic organisms. It is possible to evaluate the effect of marine environment caused marine dumping waste and wastwater by using of this SSEM.We also discussed about the proper nutrient load for Seto inland sea. As the resuls of discussion, we proposed the countermeaeures to reduce nutrient loads considering the proper nutrient load for Seto inland sea. Less

1.海洋倾倒废水生物处理工艺的建立（1）UAHB-二级接触曝气组合工艺处理难降解废水的研究探讨了UAHB反应器处理高硫高氨发酵废水中颗粒物的形成机理和处理特性。结果表明，在处理含硫和含氨废水的过程中，颗粒污泥可以得到很好的发展，且不会发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。试验结果还表明，两级接触曝气工艺适合作为UAHB的后处理工艺。因此，UAHB与两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。(2)研究 ...更多信息 两段接触曝气工艺处理高盐废水采用两段接触曝气工艺处理含高盐、高浓度有机物的磺胺废水。试验结果表明，采用二级接触曝气工艺处理磺胺废水是可行的，其负荷极限为1.85 kg-TOC/m^3/d。(3)三级处理系统处理照相废水的研究照相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是无法将其去除到允许的程度的。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。建立了基本可行的照相废水COD去除工艺.海洋倾倒废弃物和废水对海洋环境的影响评价我们建立了以生物尤其是鱼类和底栖生物为研究对象的浅海生态模型（SSEM）。利用SSEM可以评价海洋倾倒废弃物对海洋环境的影响，并对濑户内海的合理营养盐负荷进行了探讨。根据讨论的结果，提出了在合理控制濑户内海营养盐负荷的基础上，降低营养盐负荷的对策。少
