Abstract
The nutrients Phosphorous, Nitrogen and Carbon are essential for aquatic life. However, in excess they also cause serious problems. For this reason, wastewater treatment must meet nutrient effluent limits. A wastewater sample was taken near Dhahibah village from the Erbil wastewater channel in the north of Iraq. In this experiment, pure cultures of Aspergillus niger and Candida albicans were used to treat wastewater. Samples were measured for physicochemical parameters like EC, pH, Phosphate, Nitrate, Nitrite, and BOD5 using standard methods every third day during 21 days of experiment. The results revealed that Aspergillus niger had the maximum efficiency in removing BOD 5 , NH 4 , NO 3 , and EC (87.27, 89.57, 83.52, and 78.49%) respectively. On the other hand, during the experimental period, Candida albicans had the maximum efficiency in decreasing PO4, and NO2, were (91.58% and 88.89%), respectively. Statistically, there were differences (P≤0.05) between the control sample and the treated wastewater sample for both fungal stains for all parameters during the experiment.黑曲霉和白色念珠菌在污水水质改善中的应用
磷、氮和碳是水生生物所必需的营养物质。然而，过度使用它们也会造成严重的问题。因此，废水处理必须满足营养废水的限制。在伊拉克北部埃尔比勒废水通道的Dhahibah村附近采集了废水样本。本实验采用纯培养的黑曲霉和白色念珠菌处理废水。在21天的实验中，每三天使用标准方法测量样品的物理化学参数，如EC、pH、磷酸盐、硝酸盐、亚硝酸盐和BOD5。结果表明，黑曲霉对BOD5、NH4、NO3和EC的去除率最高，分别为87.27%、89.57%、83.52%和78.49%。另一方面，在实验期间，白色念珠菌对PO4和NO2的降低效率最高，分别为（91.58%和88.89%）。从统计数据来看，在实验期间的所有参数下，对照样品和处理过的废水样品之间的两种真菌污渍都存在差异（P≤0.05）。
