摘要
针对灌河口地区污染源分布特点,采用一维和二维水质模型相结合的水环境容量计算方法,对灌河的水环境容量进行了计算分析。结果表明,在90%水文保证率下,灌河COD水环境容量为4247t/a,NH3-N水环境容量为561t/a,得出灌河流域已不同程度受到污染,提出控制污染的方法建议,供相关部门在治理灌河的污染、改善灌河水环境以及开发利用灌河方面作参考。
Considering the distribution of pollution sources in the Guan River estuary region,the water environmental capacity of the Guan River was calculated and analyzed by using the way of one-dimension and two-dimension water quality mixed model.The results indicated that the water environmental capacity of the Guan River on COD and NH3-N respectively was 4247 t/a and 561 t/a under the assumption of 90% hydrological guarantee.We draw the conclusion that the Guan River has been polluted to different extents.The paper put forward some proposals for the control of the pollution in the Guan River,
