摘要
河流污染物入海通量的研究是研究海水污染的内容之一。本文对目前常用的河流污染物通量估算方法进行了分析,根据九龙江的水文水质监测数据,选择高锰酸钾指数与NH3-N作为代表性水质监测项目,利用各种估算公式进行污染物入海通量估算,对估算结果进行比较发现部分公式适用性较好。估算结果表明,2003年九龙江污染物入海通量CODMn大约为21 000 t/a,NH3-N大约为2 500 t/a。根据与其他研究结果的对比,探讨了河流污染物入海通量估算的特点,对不足之处作了说明。
Study of the contaminations fluxes from river to the sea is part of the research of marine pollution. The popular calculation formulas of contaminations fluxes in river were analyzed. According to the flow and water quabty monitoring data in Jiulong River, CODM, and NH3-N fluxes were calculated by the different formulas. The calculation results show that some formulas are effective. In 2003, the CODMn fluxes from Jiulong river to the sea was about 21 000 t/a, and the NH3-N fluxes was about 2 500 t/ a. Comparing with other＇s research results, the characteristics of the contaminations fluxes from river to the sea were discussed, and some deficiencies were also brought forward.
