【摘要】在环境容量的确定过程中,降解系数为关键影响因素,其确定的合理性,直接影响到容量的可靠性。该研究课题通过实验模拟法对黄河兰州段CODC r降解系数进行了研究,考虑到实验条件与实际河流的差异,对降解系数做了修正,并利用实际监测端面监测数据对修正后降解系数进行验证,得出黄河兰州段COD降解系数介于0.185~0.240 d-1。更多还原

【Abstract】 Degradation coefficient is a key factor in the process of environmental capacity.Its rationality directly affects the reliability of capacity.This study researched COD_Cr degradation coefficient in Lanzhou channel segment of the Yellow River by experimental simulation method.Considering the condition difference between experiment and river,COD degradation coefficient was revised.In conclusion,the monitoring data of the river was used to validate the coefficient,and the COD degradation coefficient lays in 0.185⁰.240 d^-1 in Lanzhou channel segment of the Yellow River.更多还原
