摘　　要：陕西省洛川县地处渭北黄土高原沟壑区,县区内河流在春季融雪期和夏季暴雨期泥沙悬浮物含量高,浊度骤升,用作供水水源时,严重影响制水效率,影响出厂水质。基于此,洛川给水厂增设调蓄池,一方面可对原水进行预沉处理,一方面进行水量调控保障不间断供水。通过对比分析调蓄池投入运行前后降水量与进厂水浊度变化,对改善水厂进水水质,降低药剂投加成本效果显著,为汛期高浊地表水处理提供了解决思路。Luochuan County,Shaanxi Province,is located in the gully area of the Loess Plateau in the north of the Wei River.The rivers in the county have high suspended sediment content in the spring snow melting period and summer rainstorm period,and the turbidity rises sharply.When used as a water supply source,it seriously affects the water production efficiency and water quality.Based on this,Luochuan Water Supply Plant added a regulating reservoir,which can,on the one hand,pre-settle the raw water and,on the other hand,regulate the water volume to ensure uninterrupted water supply.Upon comparing and analyzing the changes in precipitation and turbidity of incoming water before and after the regulating reservoir was put into operation,it has a significant effect on improving the inlet water quality of the water plant and reducing the cost of chemical addition.This provides a paradigm solution for the treatment of high turbidity surface water during the flood season.
