摘要
对黄河兰州段氨氮的降解规律进行了室内模拟实验研究,采用稳态一维降解模型进行了分析计算,得出氨氮的室内降解系数为0.014d-1,并根据黄河兰州段的实际情况,对其进行温度和坡度修正,计算出黄河兰州段不同水期时的氨氮降解系数.
The degradative pattern of ammonia-nitrogen in Yellow River adjacent to Lanzhou was studied experimentally with indoor simulation. One-dimensional steady degradation model was used for pollution analysis and evaluation, and it was calculated that the indoor degradation coefficient of ammonia-nitrogen was 0. 014d^-1. According to the actual conditions, this data was corrected for the temperature and gradient, so that the degradation coefficients were obtained for different periods of time.
