摘要:
南水北调水源进京后既要与地下水混合供水,又要将余裕水回灌地下保存,两地水源混合后的水质变化是人们关注的重要课题。本次研究中采集了丹江口地表水和北京调蓄池附近地下水,并开展了不同比例的混合试验。研究表明:丹江口水库水质优良;两地原水混合后,Na+、Mg2+、Cl-、SO2-4等组分表现为物理混合; Ca2+、HCO-3、pH值则受到碳酸平衡的强烈影响,当丹江口地表水占比较大时,混合溶液中硝化作用主导碳酸平衡,当地表水占比较小时,溶液中二氧化碳分压变化主导碳酸平衡。研究结果对南水北调进京后的供水具有重要意义。
Abstract:
SouthtoNorth water diversion will not only be used for supply after mixed with groundwater in Beijing, but also injected underground for save. The change in the mixed water quality is focused in this paper. Water in the Danjiangkou reservoir and groundwater in Beijing were sampled and mixed experiments were carried out. The results show that sodium, magnesium, chloride and sulfate are mixed physically and calcium, bicarbonate and pH are drastically affected by carbonate balance. When the ratio of water in the Danjiangkou reservoir to groundwater in Beijing is large, the nitrification dominates the carbonate balance. On the contrary, the change in carbon dioxide pressure affects the carbonate balance. The research results are useful to water supply for the SouthtoNorth water diversion.
