Technical field
The invention belongs to the technical field of environmental bydraulic engineering engineering research, it is related to and a kind of intends for the defeated shifting formwork of pollution of river thing
Three-dimensional sampling method.Using the sampling method and designed sampler, can be adopted simultaneously along the defeated shifting path of pollution group
Different water depth on monitoring section, the water sample at different start point distances are taken, then forms pollution of river thing concentration three-dimensional distribution map.
Background technology
Sudden water pollution event takes place frequently in recent years, carries out Pollutant Dispersion Law research in river and is particularly important.
Pollutant diffusion field test is by discharging tracer in upstream, and the water sample of downstream capture being analyzed, pass through water sample
Data result determine the Diffusion Law of different pollutants.During the defeated shifting of pollution of river thing, due to be subject to it is natural because
Element influence is sufficiently complex, so the result obtained is often comprehensive result caused by many factors.At present in the defeated shifting of pollutant
Research in terms of, indoor model test and mathematical modeling calculate all there is certain limitation (Gu Peiyu, it is tight to carry out water environments
Research and water quality model general introduction [J] traffic environment-friendlies, 1988, Z1:13-20).Therefore, in order to study the mixed of polluter in river
The rule that conjunction, defeated shifting, conversion are distributed, changed over time and space, the field test of the progress defeated shifting of pollutant is very necessary
's.
In the field test of the defeated shifting of pollutant, it should realize that the fixed point of water sample is taken, while also to make taken sample

Shield, 1995,01:8-11+60).Meanwhile the sampler provisioned in most sampling systems is generally single-point water intaking at present,
Sampler is in sampling process, after often sampling once, all needs to clean sampler, then could carry out next sampling, water intaking effect
Rate is low.And taken while realizing multiple water samples, often by increase manpower the methods of more people's operations is carried out to realize
(white light is bright, Xingan, analysis method research [J] northern environments of Chao Lumen Yellow Rivers monitoring, and 2013,01:124-126).
In addition, traditional sampler volume is larger, in sampling process, instrument will be put under water, and this may be to sample location
Flow field produces larger disturbance.
The three-dimensional sampling method of applicant design, the water sample that can adapt to different river course environments take work.This method
By the control to sampler, the route for following pollution group is realized, helps preferably to observe the defeated shifting rule of pollutant
Rule.The three-dimensional sampling method that the present invention designs needs to apply corresponding sampler, and the operating platform of the sampler is by binary
Ship is built with plank and is connected, and the equipment between two catamarans does not contact directly with water body, and the position of catamaran is then by testing people
Member is controlled by being fixed on the I-beam wheel retractable hawser on riverbank, efficiently avoid hull in moving process to water
The disturbance of body.The three-dimensional sampler of design is equipped with the multi-point sampling device voluntarily developed simultaneously, device sampler operation letter
Single, it is small to submerge water body volume, can meet simultaneously it is safe, easy to operate, to many requirements such as river flow field microvariations, and in fact
Showed to multiple sampled points simultaneously, fast sampling, reduce the priority error in sampling process, ensure that the representative of institute's water sampling
