鲁古河水库供水工程对水源区水环境影响分析

Impacts Analysis on the Water Environment in the Exporting Region of Rugu River Reservoir Water Supply Project

以鲁古河水库供水工程为例,采用"湖泊完全混合衰减模式"进行水质预测,分析工程引水后,鲁古河水库水量减少水环境容量降低可能对库内水质及下游河道用水产生的影响。预测结果表明调水后鲁古河库内BOD和氨氮增幅较小,污染物浓度可达到水质标准要求,引水后不会对下游用水量和水质产生影响。

Taking the water supply project of the Rugu River Reservoir as an example the adopting the ＂Lake totally mixed attenuation mode＂. After analyzing the water diversion from the project, the influence of watervolume and the reduction of water environmental capacity on the water quality in the reservoir and the downstream water consumptionare analyzed. The prediction results show that the BOD and ammonia nitrogen increased slightly after water bank, the concentration of pollutants can meet water quality standards,not to the downstream water diversion and water qualityinfluence.
