摘要

大多数绕道河流的发展中国家都担心水污染物。水质在农业、工业和饮用水允许范围内是一个难以解决的问题。根据它们的重要性,从Al Kut纺织厂选择了10个理化参数进行研究。近8年来,对水样的理化参数测量进行了研究,主要包括总溶解固形物TDS、TSS、Tur等10个参数。、电导率、硫酸盐SO4、氯化物、磷酸盐、COD、DO和生物需氧量BOD5。将水质检查的结果与世界卫生组织的最高允许浓度限制和伊拉克的限制进行了比较。根据研究结果,水质参数逐渐降低。结果表明:近8年来,Al-Kut TSS浓度的年递减率为71%,浊度浓度的年递减率为11.44%,氯化物和磷酸盐浓度的年递减率分别为50%和70.23%。而近8年研究期间,平均BOD5浓度呈下降趋势,Al-Kut DO浓度的年变化幅度在51%以内。

Assessment physical-chemical and biological properties of industrial wastewater in Al-Kut textile factory
Most developing countries that bypass rivers are concerned about water pollutants. Water quality within the permissible limits for agricultural, industrial, and drinking reasons is a difficult problem to solve. On the basis of their importance, ten physical and chemical parameters were chosen for this investigation from Al Kut textile factory. For the last eight years, physical-chemical parameters measurements of water samples have been researched for ten parameters are total dissolved solids TDS, TSS, Tur., Electrical conductivity, sulfate SO4, Chloride, Phosphate, COD, DO and biological oxygen demand BOD5. The findings of the water quality examination were compared to the World Health Organization's maximum permitted limit concentration and Iraqi limitations spastically. Moreover, the water quality parameters were gradually decreased according to the findings. Results shows the annual variation of Al-Kut TSS concentration with decreasing rate of (71%), Turbidity concentration with decreasing rate of (11.44%), Chloride and Phosphate concentrations within its decreasing rate of 50 % and 70.23 % respectively during the study period of the last eight years. While the average BOD5 values decrease in concentration and the annual variation of Al-Kut DO concentration within its decreasing rate of (51%) during the study period of the last eight years.
