Abstract

The invention discloses a Y-type intersection river pollutant transport and mixing simulation experiment device and a test method. The device comprises a pollutant tracer discharge device, a water flow circulation device, a flow regulating device and a measuring device. The pollutant tracer discharge device comprises an overflow flat water head drainage tank and a tracer discharge port. The overflow flat water head drainage tank is connected to the tracer discharge port through a hose. The water flow circulation device comprises an intersection angle variable and slope variable Y-shaped watertank and a reservoir. The measuring device measures conductivity of each point of the cross section and calculates the concentration of the tracer sodium chloride so that the transport and mixing variation rule of the pollutants in the Y-shaped river is acquired. The method has the characteristics of flexible change of the intersection angle and slope and provides a novel tool and method for the study of the pollutant transport law.

Description

technical field [0001] The invention relates to a simulation experiment device and a test method for pollutant transport and mixing in a Y-shaped intersecting river, and belongs to the technical field of water environment protection. Background technique [0002] The river network is an important part of the surface water circulation system, and it is also an important channel for the transport of water, pollutants and other substances in the basin. It has the characteristics of openness, randomness and self-similarity. There are a large number of intersecting estuaries in the river network. Due to the drastic change of the river channel, the water flow at the converging estuary is turbulent and mixed violently, forming stagnation area, flow velocity deviation area, separation area, flow velocity acceleration area, mixed layer area, etc. At the same time, it also affects the transport and mixing of pollutants. With the development of the economy, a large amount of pollutant...
