City's waterlogging, water resource utility model lack water-rock reactions, and runoff pollution aggravation, water ecological environment deteriorate, and promote " to reduce exploitation pair
" sponge city " construction of the influence of rainfall runoff, recovery natural water circulation " carries out in high gear throughout our country.Rainwater diameter
Stream polluting property research is the basis for carrying out " sponge city " construction, and the acquisition of rainfall runoff water sample is realize the work the
One step.To reduce manual work, guarantee the timeliness of rainfall runoff sample acquisition, various automatic sampling apparatus come into being.Mesh
Before, commercially available automatic rainfall runoff sampling apparatus is online with flowmeter, liquidometer mainly by modular program structure, presses
Time or liquid level are sampled automatically.But there is very big limitation in the application of such sampler, it is necessary to avoid severe pipeline
Otherwise condition will cause mistake or unstable reading:
(1) it should be avoided and be mounted at discharge outlet or turbulent flow
(2) probe can not be run under the conditions of lasting low liquid level
Wherein, can not low liquid level operation be such sampler maximum drawback, with currently a popular " area velocity probe "
For, liquid level can not be detected when liquid level is lower than probe positions, it is therefore desirable to which minimum liquid level is 25mm, otherwise can not
Perception also can not just be sampled.
However, height of water level in pipeline is unable to satisfy requirements above substantially at the beginning of raining or when rainfall is smaller, can not adopt
Collect the rainwater sample under the conditions of initial rainwater and light rain, but the pollutant that such rainfall runoff carries is most, is research rainwater diameter
Flow the most important part of contamination control.The missing of initial rainwater and the acquisition of small flow sample, makes automatic sampler largely
On lose timeliness meaning.
