摘要

向水体排放未经处理的废水会污染受纳水体。本研究评估了屠宰场和坎帕拉设计师排放的废水对尼日利亚阿贝奥库塔耶莫贾河水质的影响。研究人员在三个点收集了 27 份水样,长度为 180 米,历时 6 个月,评估了水样的理化参数和金属含量,并与世界卫生组织和尼日利亚标准组织的允许标准进行了比较。结果发现,大多数排放点的水平都高于其上游和下游的相应数值。发现温度、浊度、镁、碱度、溶解氧、总悬浮物、磷酸盐、铅、生化需氧量和钾超过了世界卫生组织和尼日利亚标准组织规定的河水正常水平,而总溶解氧、总悬浮物、钙、氯、硝酸盐、硫酸盐、铁和化学需氧量等参数则低于标准。总大肠菌群值高于国家和国际允许限值,表明受到人类污水或动物粪便的污染。水质指数表明,受污染的水不适合饮用。研究结果表明,屠宰和扎染活动影响了耶莫贾河的水质。因此,屠宰场和纺织业产生的废水应经过处理后再排入水体。

Impact of abattoirs and local textile (Adire and Kampala) effluents on Yemoja River in Abeokuta, Nigeria
Discharge of untreated wastewater into water bodies pollutes the receiving waters. This study assessed the impact of abattoir and Kampala designers' effluent discharge on the water quality of the Yemoja River in Abeokuta, Nigeria. Twenty-seven water samples collected at three points, covering 180 m length, for 6 months were assessed for physicochemical parameters and metals and compared with the World Health Organization and Standard Organization of Nigeria permissible standards. Most discharge point levels were found to be higher than their corresponding upstream and downstream values. Temperature, turbidity, magnesium, alkalinity, DO, TSS, phosphate, lead, BOD and potassium were found to be in excess of normal levels for river water as prescribed by the World Health Organization and Standard Organization of Nigeria while parameters like TDS, TS, calcium, chloride, nitrate, sulphate, iron and COD were lower than the standards. The total coliform values were higher than both national and international permissible limits, indicating contamination by human sewage or animal droppings. The water quality index indicated polluted water that is unfit for consumption. Findings from this research indicate that butchering and tie-and-dye activities have impacted river Yemoja water quality. Therefore, wastewater from the abattoir and textile industries be treated before discharge into water bodies.
