Problems solved by technology

The migration process of pollutants in karst pipelines may be affected by many factors, such as the roughness of the pipeline wall, the internal structure of the pipeline, and the adsorption of sediments in the pipeline. It is generally believed that molten pools in pipelines can reduce the peak concentration of pollutants and increase the tailing time of pollutants. At present, most of the effects of molten pools in pipelines on pollutant migration are qualitatively understood, and different methods are rarely discussed.

Abstract

The invention discloses a device for simulating influence of a puddle in a pipeline on pollutant transport and a working method. The device comprises a constant-head water tank, a circular pipe, a flow control valve, an electromagnetic flowmeter, a carrier, a rectangular-outlet water tank and a syringe, wherein when single pipeline solute transport is simulated, the carrier is a circular pipe; when pipeline and water tank solute transport is simulated, the carrier is a water tank. The device has the advantages that the outlet solute concentration curve under different experiment conditions can be obtained fast by changing the pipeline structure and regulating flow rate, and a quite effective method is provided for the quantitative analysis of the influence of the puddle in the pipeline on solute transport.

Description

technical field [0001] The invention belongs to the technical field of hydrogeology, and specifically refers to a device and a working method for simulating the influence of melting pools in pipelines on pollutant migration. Background technique [0002] Karst pipelines are widely distributed in karst areas in Southwest my country, and they are the most important channels for the migration of pollutants in karst areas. With the development of society and economy, the pollution in this area is becoming more and more serious. A large amount of industrial and domestic sewage is directly discharged into karst pipelines through sinkholes, etc., and quickly migrates and spreads to other places, causing extensive groundwater pollution in this area. Studying the migration process of solutes in karst pipelines is of great significance for the prediction and prevention of groundwater pollution in southwest karst areas. The migration process of pollutants in karst pipelines may be aff...
