Investigation of construction of water resource use system in drought and water shortage region

最近，由于水资源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进先进的水处理技术、用水网络系统技术、用水合理化技术和风险管理技术，构建完整的水资源利用体系。然后，以干旱缺水地区欠发达地区水资源的有效利用为背景，考察了膜法净水技术对生活、农业和工业用水的有效利用。此外，由于无论是水处理还是能源方面的基础设施都是一个不发达的地区，对这些水处理的供应…最后探讨了更多利用自然能源的技术，从引水区供水量和水质两个方面考察了水资源利用网络建设的评价方法，并通过对山西省大同市、抚顺市、沈阳市等干旱缺水地区的生活用水、工农业用水、水处理技术和水质的调查，了解了引水区的供水现状。收集了抚顺市生活、农业、工业等方面的水资源数据，对抚顺市某一特定区域的供水假设区域进行了水质和水量的优化模拟技术检验，并在抚顺市大学校园内进行了日本已投入实际使用的膜生物反应器(MBR)对生活污水的净化检测。考察了BOD、COD、NH4-N、总P、含油量、浊度、溶解氧、pH等水质指标以及污泥、膜压、流速等膜生物反应器的运行条件。因此，能够处理出优良的水质。此外，在抚顺市的大学校园内还可以建设风力发电系统对MBR的供电。较少

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
