【摘要】：志丹县地处陕西省延安市西北部，为发展区域经济，优化产业结构，以当地丰富的能源产品为突破，建设能源化工园区。但该区域属半干旱地区，水资源总量不足，属资源性缺水，同时现有超采地下水、牺牲生态水、挤占农业水的格局，已造成一系列严重水环境问题，更严重制约了志丹县能源化工园区的建设发展。论文以志丹县能化园区水资源的开发和优化配置为研究对象，在研究其水资源开发利用过程中，坚持控制地下水开采、扩大非常规水资源利用规模的原则，对非常规水资源进行综合开发利用和优化配置。针对能化园区各途径用水所需水质和水量差异，提出了分质处理、分质供水，水质-水量联合优化配置的水资源配置模式，研究结果表明能化园区现有近期水资源总量12.39万m3/d，，远期13.39万m3/d，可满足能化园区近远期用水需求。水质-水量联合优化配置结果如下：（1）在50%供水保证率下，近期远期各水源供水量分别为：地下水300m3/d、460m3/d，地表水3700m3/d、7540m3/d，再生水4000m3/d、8000m3/d；（2）在75%供水保证率下，近期远期各水源供水量分别为：地下水300m3/d、460m3/d，地表水1700m3/d、3540m3/d，再生水6000m3/d、12000m3/d；（3）在90%供水保证率下，近期远期各水源供水量分别为：地下水300m3/d、460m3/d，地表水500m3/d、1140m3/d，再生水7200m3/d、14400m3/d。本研究对于实现志丹能源化工产业的合理、有序发展，进一步推促志丹县经济社会发展具有重大现实意义。
[Abstract]:Zhidan County is located in the northwest of Yan ' an City of Shaanxi Province . In order to develop regional economy and optimize the industrial structure , the local rich energy product is the breakthrough and the energy chemical industrial park is built . However , the region belongs to semi - arid area , the total amount of water resources is insufficient , and it is resource - deficient . At the same time , it has caused a series of serious water environmental problems , which has seriously restricted the construction and development of the energy chemical industrial park in Zhidan County .

In this paper , the development and optimization of water resources are studied in Zhidan County , which is based on the principle of controlling groundwater exploitation and increasing the utilization scale of unconventional water resources . The water resources allocation model is proposed . The results show that the total water resources in the park is 123.39 million m3 / d , and the long term is 13.390,000 m3 / d . The results show that the water quality - water quantity joint optimization collocation results are as follows :

( 1 ) At the 50 % water supply guarantee rate , the water supply quantity in the near future is 300m3 / d , 460m3 / d , 3700m3 / d of surface water , 7540m3 / d , 4000m3 / d of reclaimed water and 8000 m3 / d ;

( 2 ) At 75 % water supply guarantee rate , the water supply quantity of each water source in the near future is 300m3 / d , 460m3 / d , surface water 1700 m3 / d , 3540m3 / d , reclaimed water 6000m3 / d , 12000m3 / d , respectively ;

( 3 ) At 90 % water supply guarantee rate , the water supply quantity in the near future is 300m3 / d , 460m3 / d , surface water 500m3 / d , 1140m3 / d , reclaimed water 7200m3 / d , 14400m3 / d , respectively .

This research is of great practical significance to realize the reasonable and orderly development of Zhidan energy chemical industry and further promote the economic and social development of Zhidan County .
