Description
Technical field
The present invention relates to environmental monitoring processing technology field, the use system of more particularly to beneath water.
Background technology
Underground water pollution is due to the phenomenon that human factor causes ground water degradation.The reason for underground water pollution, is main
Have：Industrial wastewater is directly discharged to underground, and contaminated surface water is invaded in underground reservoir, human and animal excreta or is made because excessive
With agricultural chemicals, contaminated water permeates the ground.The result of pollution is to make harmful components in underground water such as phenol, chromium, mercury, arsenic, put
The content of penetrating property material, bacterium, organic matter etc. increases.The underground water of pollution has harm to health and industrial and agricultural production.
At present, groundwater monitoring is mainly using structure monitoring well, the method that groundwater abstraction is analyzed from monitoring well.
After reducing sampling error, it is necessary to which the underground water being detained in monitoring well is discharged, then using new water, as well-flushing sampling method.It is existing
Some well-flushing sampling systems it is complicated, reliability, the accuracy of sampling need to be improved.

Process, first pass sampling process and second time sampling process；
In the multipass washing well process, during first pass well-flushing, the well depth of monitoring well is detected and by well using liquid level sensor
Deep data feedback is to PLC control cabinet, and PLC control cabinet judges whether to be approximately equal to actual well depth, if then control flexible pipe recover is received
Pumpback water tube hose waits liquid level sensor to detect water level and is back to elemental height, carry out second time well-flushing to elemental height；If not
Then circulate first pass well-flushing；The process of second time well-flushing is identical with first pass washing well process, and the 3rd is carried out again after second time well-flushing
All over all over well, the 3rd time washing well process is identical with first pass washing well process, is completed to well-flushing；In the multipass washing well process, draw water
Water in monitoring well is evacuated in well-flushing bucket by pump；
In the first pass sampling process, the water in the monitoring well after the 3rd time well-flushing is evacuated to first and adopted by suction pump
In sample bucket, the water quality parameter in Water quality detector detection water sample in the first sampling tank, and store into PLC control cabinet；According to
Washing well process drains the water in monitoring well, and after carrying out second time sampling after backwater, during second time sampling, suction pump is by monitoring well
Water be evacuated in the second sampling tank, the water quality parameter in Water quality detector in the second sampling tank detection water sample, and storing to PLC
In switch board；PLC control cabinet is contrasted to the water quality parameter in the first sampling tank with the water quality parameter in the second sampling tank, root
Control whether the water in monitoring well being directed into the sampling bottle on automatic rotation sampler tray according to comparing result.
Further, in the comparing result, if first pass sampling second time sampling between determine pH, electrical conductivity and
Dissolved oxygen error is no more than ± 0.2, ± 5% and ± 5% respectively, then PLC control cabinet controls the first sampling tank and the second sampling tank
In water sample be directed into sampling bottle；If first pass is sampled, pH, electrical conductivity and the dissolved oxygen determined between second time sampling is missed
Difference not Chao Guo ± 0.2, ± 5% and ± 5%, then again all over carrying out first pass sampling and the second sampling process.
The technical effects of the invention are that：
The present invention controls whole sampling process to carry out automatically by PLC, without personal monitoring, and system architecture is simple, sampling
It is easy to operate；Using double sampling Comparative result principle, its reliability of sampling, the degree of accuracy are significantly improved.
