Load, helps to formulate targetedly pollution control plan.
In view of the presence of runoff first flush effects, in the research to rainfall runoff, its common method of sampling is first
Every 10min in a sample, 30min ~ 60min is taken to take in a sample, 60 ~ 90min often per 5min in the preceding 30min of beginning discharge series
30min takes a sample.As can be seen here, rainfall is sampled comparatively dense initial stage.Existing runoff acquisition method is mainly including manually and certainly
Dynamic makeup is put.Hand gear can not measure real-time runoff rate, disturb the flow direction of runoff again, the sample representativeness of collection compared with
Difference；In addition, at rainfall initial stage, because sampling time comparatively dense causes higher to manpower requirements, 2 people are at least needed to coordinate
Into.Though and automation equipment can obtain data on flows, and easily collecting runoff water sample, equipment cost is higher, and part is filled
Put and also need to lay pipeline, cause flexibility poor so that the practical application of such device.To sum up, runoff can be realized
Amount monitoring and water quality gather difunctional, are rain but also with monitoring sampling apparatus the advantages of may move, install simple, with low cost
The product that water runoff research field is badly in need of.
