摘要
Abstract
In order to determine the degradation coefficients of pollutants, field observation of water quality in the Jiulongtan Reservoir was conducted during a low water period;the concentration distributions of main water quality factors, such as BOD5 , CODCr , and NH3-N, in specific sections were obtained through water quality sampling and laboratory experiments;and the longitudinal degradation coefficients of water quality factors in the Jiulongtan Reservoir were calculated using three cross-sectional characteristic concentration values. The results show that the degradation coefficients calculated by the perpendicular bisector surface concentration and section-averaged concentration are close, while the one calculated by the surface-averaged concentration presents a larger deviation, which is considered to be the result of combined influence and interaction of various complicated factors. When prototype observation is used to determine the degradation coefficients of pollutants in reservoirs of low-dam and run-of-river hydropower stations without branches or sewage inlets and there is a large number of monitoring sections, in order to improve the work efficiency, it is feasible to obtain the degradation coefficients only from the water samples at the perpendicular bisector surface of cross-sections based on verification in advance.关键词
