摘要
以鄂尔多斯市为典型地区,针对区域矿产资源丰富、水资源贫乏、生态环境脆弱、水资源供需矛盾突出的问题,在各种非常规水资源可利用量分析的基础上,研究非常规水源利用技术,提出多种水源统一配置、联合调度的方案。结果表明,鄂尔多斯市常规水资源(地表水及地下水)有限,通过实施污水处理再生水、利用煤炭矿井水、淡化处理微咸水(矿化度2~5g/L)、开采岩溶水、潜流以及雨水利用等各种非常规水源的综合利用,2020年各种非常规水源利用量可达到3.310亿m3,可有效增加区域可供水量,缓解区域供需矛盾,支撑经济社会持续发展。研究提出的非常规水源利用策略对于我国西北缺水地区具有借鉴意义。
Taking Erdos City as an example, with regard to the problems of rich mineral resources,deficient water resources, fragile ecological environment and serious contradiction between water supply and demand in the area, the techniques of utilizing non-conventional water are studied and the unified allocation and joint scheduling of various water sources is proposed by analyzing a variety of available quantity of non-conventional water resources. The results show that the conventional water resources( surface water and groundwater) in Erdos City are limited,and the available quantity of non-conventional water resources can be 331 million m3 in 2020 through the integrated utilization of reclaimed water from wastewater treatment,coal mine water,brackish water from desalination treatment( salinity of 2 ~ 5 g / L),exploited karst water,underflow and rainwater. It can effectively increase the available water supply in Erdos City and mitigate the contradiction between regional water supply and demand so as to support the sustainable development of social economy. The proposed strategy of non-conventional water utilization is of reference significance for the water-deficient areas in Northwest China.
