基于ADCP测量的钱塘江主要断面污染物通量研究

Study on pollutant flux of main sections in Qiantang River based on ADCP

用声学多普勒流速剖面仪(Acoustic Doppler Current Profiler,ADCP)获取河流断面的流量资料,结合水质分析所得的高锰酸盐、氨氮、总磷、石油类等污染物浓度资料,分析了钱塘江主要断面的污染物通量。结果表明,污染物通量研究将水质和水量统一起来考虑,很好的反映了污染负荷大小,是全面了解和评价河流主要断面污染物输送量和贡献量的有效手段,今后在治理流域水污染时应重视对河流污染物通量的研究。

Based on the flux data of fiver sections obtained with ADCP and the materials of pollutant density such as CODMn, NH3 - N, TP and petroleum etc., the pollutant flux of the main sections in Qiantang River is analyzed in the paper. The result indicates that the study on pollutant flux which considers water quality and water quantity reflects well the mnount of pollution load. It is an effective way to understand and evaluate the sending amount and contributing quantity of the rain section pollutant. The study on pollutant flux in rivers is carried out while controlling river pollution in the future.
