A 3D Sampling Method for Simulation of River Pollutant Transport

Abstract

The invention provides a three-dimensional sampling method for simulating transport of river contaminations. The method is characterized in that during contamination transport on-site simulation test, a catamaran reaches a testing section before contamination clusters; as the contamination clusters approach the testing section, the position of the catamaran is adjusted so as to allow the contamination clusters to be located between two boats and to be free of disturbance; and then a multi-point sampler is used to extract water samples at different water depths and different distances from an initial point so as to realize measurement of three-dimensional distribution of the concentration of the river contaminations. The three-dimensional sampling method provided by the invention realizes simultaneous and rapid sampling of a plurality of sampling points and guarantees representativeness and authenticity of the water samples.

Description

technical field

[0001] The invention belongs to the technical field of environmental water conservancy engineering research, and relates to a three-dimensional sampling method for river channel pollutant transport simulation. Using this sampling method and the designed sampling device, water samples at different water depths and different starting distances on the monitoring section can be taken simultaneously along the transportation path of the pollution mass, and then a three-dimensional distribution map of river pollutant concentration can be formed. Background technique

[0002] In recent years, sudden water pollution incidents have occurred frequently, and it is particularly important to study the law of pollutant diffusion in rivers. The pollutant diffusion field test is to release the tracer in the upstream, analyze the water samples collected downstream, and determine the diffusion law of different pollutants through the data results of the water samples. In the pr...
