第三排水沟水质对黄河水质的输入响应关系研究

Inputting and Responding Relationship of Third Drain Water Quality and Yellow River Quality

对第三排水沟入黄口和黄河宁夏出境断面水质因素进行分析,选取主要污染因子,寻找相关系数,建立第三排水沟入黄口水质、水量变化对黄河宁夏出境断面污染特征变化的水环境输入响应模型.采用该模型对第三排水沟排入黄河后,其水质对黄河水质的影响进行预测.以此为依据,研究了第三排水沟排放总量及污染治理途径,为确保黄河宁夏段出境断面水质达到要求提供理论参考.

The water quality factors for the third drain entrance to the Yellow River and the Yellow River exit section of Ningxia are analyzed. Choosing the main pollution factor and getting correlation coefficient, the responding model for water quality of the third drain entrance to the Yellow River and the influence of the variance of the water amount on the changes of the pollution characteristic of Yellow River exit section of Ningxia are established. With the model it gives a forecast of the influence of the water quality of the third drain entrance to the Yellow River of the Yellow River quality. Based on this, the prevention and the control approaches for the third drain＇s water pollution and the total loads amount are proposed so that the water quality for the Yellow River exit section of Ningxia could be met the national standards.
