柴河水库水环境容量研究

Research on Water Environmental Capacity of Chaihe Reservoir

针对柴河水库污染问题,考虑有机物沉降和藻类死亡对水环境容量的影响,改进了有机物降解模型,并利用Dillion模型分别计算了COD、BOD5、NH4-N、TP、TN 5种污染物的水环境容量。结果表明,TN、TP的水环境容量超标,改进后的模型提高了水环境容量计算的准确性,可供借鉴。

In view of the Chaihe reservior pollution problem, the influence of organic sedimentation and algal death on water environmental capacity is discussed. Then the organic matter degradation model is improved. At the same time, Dillion model is used to calculate five kinds of pollutant water environmental capacity, which includes COD, BODs, NH4-N, TP and TN. The results show that the water environmental capacity of TN and TP are over standard. The im- proved model enhances the accuracy of water environmental capacity calculation, which can be used to calculate similar water environmental capacity.
