Problems solved by technology

However, due to the characteristics of multi-channel continuous monitoring wells, the number of each monitoring hole is large and the aperture is small, the existing groundwater sampling equipment cannot quickly realize the simultaneous collection of porous samples
In addition, the small-diameter inertial pump can collect water samples from continuous multi-channel monitoring wells, but due to its operating power, it will stir the groundwater in continuous multi-channel monitoring wells, thereby affecting the representativeness of groundwater samples
Therefore, the current groundwater sampling equipment to collect continuous multi-channel monitoring wells mainly has problems such as long sampling time and large disturbance.

Abstract

The invention relates to a quick acquisition device for groundwater samples of a continuous multi-channel monitor well. The acquisition device comprises a hollow distributor, wherein the distributor is provided with a plurality of ports; one port is connected with a pump, and the rest ports are connected with ports of water outlets of sampling bottles respectively; the water inlets of the sampling bottles stretch to the sampling position of the monitor well; the water outlets and the water inlets of the sampling bottles are all provided with water stopping valves; the ports, which are connected with the water outlets of the sampling bottles, of the distributor are provided with electronic liquid level valves respectively. The invention further discloses a method by adopting the acquisition device for sampling. By adopting the acquisition device and the method, the sampling time of the continuous multi-channel monitor well can be shortened, and the outdoor groundwater sampling efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of groundwater environment monitoring, and in particular relates to a rapid collection device for groundwater samples suitable for continuous multi-channel monitoring wells. [0002] The present invention also relates to a method for sampling using the above-mentioned collecting device. technical background [0003] At present, with the continuous improvement of groundwater environmental monitoring requirements and the mastery and accurate description of groundwater pollution distribution characteristics, different types of multi-level monitoring wells have been developed. Continuous multi-channel monitoring well is a new type of multi-level monitoring well. It can provide multiple different monitoring areas, and a continuous multi-channel monitoring well can be equivalent to multiple single-pipe monitoring wells. The continuous multi-channel tube monitoring well realizes the purpose of monitoring multi-la...
