项目摘要

Recently, the expansion of the region due to dryness of the water resource becomes a serious problem in many countries including the developing country. Moreover, the damage to the ecosystem because of the water pollution is also serious problem, and it is a pressing need to introduce an advanced water treatment technique, the water use network system technology, the water use rationalization technology, and the risk management technology in such a region and to construct an integrated water resource use system Then, the use to daily life, agricultural, and industrial water of water purification technology by the utilization of membrane that is effective as the small-scale decentralized technology was examined in the background of effective use for the water resource in the undeveloped area in the drought and the water shortage region. In addition, because the infrastructure in not only the water treatment but also energy was an undeveloped region, the supply to those water treatment t … More echniques by natural energy was examined Finally, the evaluation method of the construction of the network for water resource utilization was examined from the dosage of the water supply and the water quality in the introduction region.Then, the current state for the water supply was understood by the investigations such as the water resource use for life, agriculture and industry, water treatment technology and water quality in droughts and water shortage region such as Datong city of Shanxi Province, Fushun city and Shenyang city of Liaoning Province in China. The data of the water resource concerning life, agriculture, and industry was collected, and the optimization simulation technique of the water quality and the volume of water was examined in the region that had been assumed for those water supplies in a specific region in Fushun city.Concretely, the purification examination of the life wastewater by the membrane bio reactor (MBR) that had been put to practical use in Japan had been performed in the campus of the university in Fushun city. The water qualities such as BOD, COD, NH_4-N, total-P, oils, turbidity, dissolved oxygen and pH and the operation conditions in MBR such as sludge, membrane pressure and flow rate were investigated. Consequently an excellent water quality was able to be processed. Moreover the electric power supply to the MBR by the wind power generation system could be constructed in the campus of the university in Fushun city. Less

近年来，由于水资源的枯竭而导致的区域扩张成为包括发展中国家在内的许多国家面临的一个严重问题。此外，水污染对生态系统的破坏也是一个严重的问题，迫切需要在该地区引入先进的水处理技术、用水网络系统技术、用水合理化技术和风险管理技术，构建水资源综合利用体系，实现水资源在生活、农业、在有效利用干旱缺水地区的欠发达地区的水资源的背景下，研究了作为小型分散技术有效的膜利用水净化技术和工业用水。此外，由于水处理和能源方面的基础设施都是欠发达地区，因此这些水处理设施的供应 ...更多信息最后，从供水量和引入区水质两个方面对水资源利用网络建设的评价方法进行了探讨，并通过生活、农业和工业用水调查，了解了水资源利用现状，介绍了山西省大同市、辽宁省抚顺市、沈阳市等干旱缺水地区的水处理技术和水质状况。以抚顺市为例，收集了抚顺市生活、农业、工业等水资源的数据，并对抚顺市生活、农业、工业等水资源的供水区域进行了水质水量优化模拟技术研究，具体而言，膜生物反应器（MBR）对生活污水的净化试验在抚顺市的大学校园里，考察了处理后的水质（BOD、COD、NH_4-N、总磷、油类、浊度、溶解氧、pH）以及MBR的运行条件（污泥、膜压、流量）。因此，能够处理优良的水质。此外，抚顺市大学校园内还可建设风力发电系统为MBR供电。少
