STUDY ON DESIGN OF SEWAGE SYSTEMS HAVING DISASTER PREVENTION FUNCTIONS

研究的目的是为现有的污水处理系统增加防灾功能。坂神大地震后期证明，饮用水，厕所冲洗水，灭火用水在灾难中被耗尽。污水系统是城市中心区的管道和处理设施网络。它可以作为水源，为城市人口提供避难所。利用地理信息系统对东京阿达奇地区地震中的水资源管理进行了模拟研究。模拟结果表明，在这个词的某些部分可能缺乏足够的水来区分火灾和以后的卫生使用。这些沃茨可由通过适当方法处理的废水补充。固定化细菌处理废水的实验研究表明，固定化细菌处理废水可快速获得非接触式水质，而膜处理废水可获得高质量的水质，除饮用水外，还可用于卫生和其他用途。

The objectives of the study is to add the disaster prevention function to the present sewage systems. It was proved from the late Hanshin Great Earthquake that all kinds of water, i.e., drinking water, toilet flushing water, and fire extinguishing water, was depleted in the disaster. Sewage systems are networks of pipelines and treatment facilities in the middle of urban area. It can work as a source of water and provide a refuge to the urban population. A simulation study on water management in an earthquake was carried out in Adachi word of Tokyo using GIS systems. The result of the simulation showed that some parts in this word may lack sufficient water to distinguish fires and later sanitary use. These waters may be supplemented by wastewater treated by appropriate methods. Experimental studies on wastewater treatment with immobilized bacteria showed that it can be used a s a rapid treatment methods to create non-contact water, while membrane treatment can provide high quality water which can be used for sanitary and any other purposes except for drinking water.
