吐鲁番大草湖矿泉水水源地允许开采量评价研究
|
摘要
以新疆吐鲁番市大草湖水源为研究对象,在对研究区地下水含水层特征、补径排条件以及水文地球化学特征进行分析的基础上,对研究区矿泉水的水质进行评价,并通过泉水流量衰减方程计算大草湖水源地允许开采量,结果可知:研究区内含水层主要为单一结构的孔隙潜水含水层,区内东北部小范围含水层富水性为丰富,单井涌水量在1 000～5 000 m~3/d,其余区域含水层富水性为中等,单井涌水量在100～1 000 m~3/d;矿泉水中锶的含量在0.41～0.44 mg/L之间,含量较稳定,水温在12℃～14℃,符合饮用天然矿泉水水质要求,可定名为锶型饮用天然矿泉水。计算出的大草湖水源地保证程度大于95%的流量为2 710×10~4 m~3/a,而矿泉水厂年取水量10×10~4 m~3/a(273.97 m~3/d)只占剩余水量的1.19%,不会对现状用水户造成影响,保证程度高,可作为矿泉水开发的允许开采量。研究结果为区域后期矿泉水的开发利用提供了水文地质依据。
Based on the analysis of the water source of the Dacao Lake in Turpan City, Xinjiang, based on the analysis of the characteristics of groundwater aquifer, the conditions of the drainage and the hydrogeochemical characteristics of the study area, the water quality of the mineral water in the study area was evaluated and passed through the spring water. The flow attenuation equation is used to calculate the allowable amount of water in the Dacao Lake water source. The results show that the aquifer in the study area is mainly a single structure pore aquifer, and the water in the small aquifer in the northeastern part of the area is rich in water. The water in a single well is 1 000～5 000 m~3/d, the water content in the remaining aquifers is medium, the water inflow in a single well is 100～1 000 m~3/d; the content of strontium in mineral water is between 0.41～0.44 mg/L, the content is relatively stable, and the water temperature is 12℃～14℃, in line with the water quality requirements of drinking natural mineral water, can be named as drinking natural mineral water. The calculated flow rate of the Dacao Lake water source is greater than 95%, which is 2 710×10~4 m~3/a, while the annual water intake of the mineral water plant is 10×10~4 m~3/a(273.97 m~3/d), which only accounts for 1.19% of the remaining water. The current situation of water users has an impact, and the degree of assurance is high, which can be used as the allowable mining amount for the development of mineral water. The research results provide hydrogeological basis for the development and utilization of mineral water in the later period of the region.
