石油类在河流中自净能力的研究

Research of Petroleum Self-purlfication in a River

根据河流的特点，利用示踪剂对河流中石油类污染物的衰减情况进行了分析，建立了污染物扩散模式，确定了河流不同断面的石油通量，求出了石油类污染物的衰减系数。为污染物的排放量和河流环境容量的确定提供了保证。

According to the character of a river makes use of trace regent to analysis the decay character ofpetroleum. On the meantime establishes spreading models and ensure petroleum discharge and decaycoefficient. On the basis of these affirm pollutant discharge amount and environmental capacity.
