摘要
近年来,由于降水稀少,水流量减少,艾因扎达大坝的水量出现赤字,导致大坝的蓄水量下降到 8.3%。我们研究的主要目的是通过对艾因扎达大坝未经处理(原水)和处理过的水样进行物理化学分析,评估这两种水的水质。根据分析结果,处理过的水的物理化学质量令人满意,因为所有样本都符合阿尔及利亚标准。经过处理的水的有机物浓度为 4.94 毫克/升,这是造成大坝水气味和味道不佳的主要原因。为解决这一问题,今年将通过采用新型臭氧消毒方法(臭氧消毒)来改进 Ain Zada 大坝处理站。艾因扎达大坝处理过的水的水质指数(WQI)表明,2022 年 2 月至 5 月期间的饮用水生产非常适宜。根据获得的水质指数值,每种方案可分为两个水质类别:处理后的水质为优和良,原水水质为优和差。四月份的水质明显下降,处理水的水质指数上升(25 < WQI .该月水质下降的原因可能是溪流变化、农业活动和城市污水排放。因此,必须优先减少这些污染源,以保护水资源和提高流域内的水质。
Assessment of the Physico-Chemical Quality of Untreated and Treated Water Using Water Quality Index (WQI) in the Ain Zada Dam, East Algeria
The Ain Zada dam is experiencing a deficit in recent years due to scanty precipitation and reduced water flow, resulting in the dam’s water reserve dropping to 8.3%. Our study’s primary objective is to assess the quality of both untreated (raw) and treated water from the Ain Zada dam by conducting physico-chemical analyses on both samples. Based on the findings, the physico-chemical quality of the treated water is deemed satisfactory, as all samples adhere to Algerian standards. The treated water exhibits an organic matter concentration of 4.94 mg/l, which is the chief contributor to the unfavourable odour and taste of the dam water. To address this, enhancements will be made to the Ain Zada dam treatment station this year through the adoption of a novel ozone disinfection method (ozonation). The Water Quality Index (WQI) for treated water from the Ain Zada dam indicates a favourable suitability for drinking water production from February to May 2022. Two quality categories are discernible for each scenario based on the obtained WQI values: excellent and good for treated water, and excellent and poor for raw water. Water quality diminishes notably in April, where the treated water quality index rises (25 < WQI . 50), while the raw water’s quality classifies as poor (WQI > 50). The decline in water quality during this month can be attributed to stream variations, agricultural activities, and urban wastewater discharges. Consequently, it is imperative to prioritise the reduction of these pollution sources to safeguard water resources and enhance water quality within the watershed.
期刊介绍:
Asia, as a whole region, faces severe stress on water availability, primarily due to high population density. Many regions of the continent face severe problems of water pollution on local as well as regional scale and these have to be tackled with a pan-Asian approach. However, the available literature on the subject is generally based on research done in Europe and North America. Therefore, there is an urgent and strong need for an Asian journal with its focus on the region and wherein the region specific problems are addressed in an intelligent manner. In Asia, besides water, there are several other issues related to environment, such as; global warming and its impact; intense land/use and shifting pattern of agriculture; issues related to fertilizer applications and pesticide residues in soil and water; and solid and liquid waste management particularly in industrial and urban areas. Asia is also a region with intense mining activities whereby serious environmental problems related to land/use, loss of top soil, water pollution and acid mine drainage are faced by various communities. Essentially, Asians are confronted with environmental problems on many fronts. Many pressing issues in the region interlink various aspects of environmental problems faced by population in this densely habited region in the world. Pollution is one such serious issue for many countries since there are many transnational water bodies that spread the pollutants across the entire region. Water, environment and pollution together constitute a three axial problem that all concerned people in the region would like to focus on.
