摘要

地表水评估对于制定准确的水资源管理计划至关重要。本次调查的重点是印度尼奥拉-山谷国家公园边缘地区的原水水源尼奥拉河的水质分析、处理和经济可行性。皮尔逊相关性表明,温度与总固体(TS)之间呈正相关(0.629),而溶解氧与其他参数之间呈负相关(-0.23)。在方差分析中,除 BOD5 外,其他参数的 F 值均大于 1。水质指数(WQI)的测定是为了了解河水是否符合下游边缘地区当地居民的饮用水要求。由于下游的大肠菌群数量较高(约为 4.5/100 mL),因此需要设计一种先进的处理方法,即电化学氧化批式反应器。为了保持水质等级,必须对水效益进行估算。经计算,生活和非生活用水量分别为 5,314,400 升/年和 1,470,000,000 升/年。可获得性和无税可能会导致水资源的过度开发,这为货币评估(695.29 美元)铺平了道路。本研究概述了 Neora 河的潜力,从长远来看,政府可通过水开发政策恢复该河的水量。

Water quality analysis, treatment, and economic feasibility of water services of the Neora River in the fringe area of Neora-Valley National Park, India
Assessment of surface water is essential for an accurate water management plan. The present investigation was focused on quality analysis, treatment, and economic feasibility of the River Neora, a source of raw water in the fringe area of the Neora-Valley National Park, India. Pearson's correlations showed a positive correlation (0.629) between temperature and total solids (TS), whereas a negative correlation (−0.23) for dissolved oxygen with other parameters. In ANOVA, F-value (>1) was obtained for all the parameters except BOD5. The water quality index (WQI) was determined to find out whether the river water meets the drinking water requirements for local inhabitants in the lower fringe. A high coliform count (approximately 4.5/100 mL) in downstream further warranted to design of an advanced treatment, the electrochemical oxidation batch reactor. To maintain the water quality grade, the estimation of water benefits was mandatory. The water consumption for domestic and non-domestic purposes was calculated at 5,314,400 and 1,470,000,000 L/yr, respectively. Obtainability and no tax coverage might have led to the overexploitation of water, which paved the way for monetary evaluation (695.29 US$). This study provided an overview of the potential of River Neora, which can be restored in the long run by adopting the water development policies by the government.
