Embodiment Construction

[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0033]Specifically, in order to solve the waste of manpower caused by manually determining the time point when the water quality index is stable in the prior art, slow down the sampling speed, and cause the groundwater level to drop too much to obtain representative water samples, reduce data processing accuracy and other issues, the embodiment of the present invention provides an automatic, intelligent micro-flushing well type automatic sa...

Abstract

The invention discloses a micro-flushing groundwater automatic sampling system. Groundwater is pumped in a micro-flushing mode by using a preset groundwater pumping strategy, real time acquisition and quality index analysis are carried out on the pumped groundwater to automatically and intelligently determine the micro-flushing process and optimize the pumping speed of the groundwater in order to obtain stable water quality indexes within a shortest time and to obtain an aquifer representative water sample by beginning the water sample acquisition at a most reasonable time, so the problems of labor waste, slow sampling speed and no representative water sample obtaining caused by the adjustment of the pumping speed of the groundwater and the determination of the water quality index stability time point in a manual mode are solved, and the problem of data processing inaccuracy caused by large error of data after-processing due to wrong manual recording is avoided. The real time acquisition and water quality index analysis of the pumped groundwater are carried out to realize corresponding water quality monitoring and predicating functions.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a micro-flushing well type automatic sampling system for ground water. Background technique [0002] Groundwater pollution mainly refers to the phenomenon that human activities cause changes in the chemical composition, physical properties and biological characteristics of groundwater, resulting in the decline of groundwater quality. Groundwater pollution has the characteristics of slow process, difficult discovery and difficult treatment. Once the groundwater is polluted, it will take at least ten years or even decades to restore the water quality. This is because groundwater pollution requires special monitoring to determine the types and concentrations of pollutants, and such monitoring often results in last for several years to decades. [0003] Specifically, at present, the monitoring of groundwater pollution mainly adopts the method of constructing monito...
