Problems solved by technology

[0004] In recent years, various pollutant migration models have been established to simulate the fate and migration of pesticides and other agricultural chemicals and their residues in soil and groundwater; however, such studies are limited to indoor simulations or computer simulations, and cannot It truly reflects the actual complex and changeable field conditions, and there is still a lack of devices that can monitor shallow groundwater pollutants for analysis and treatment of shallow groundwater; Groundwater pollutant monitoring device to optimize the solution to the above problems

Embodiment

[0040] Such as figure 1 and 2As shown, a shallow groundwater pollutant monitoring system includes: a monitoring well and a sampling assembly, and the monitoring well is divided into a protective column 1, an intermediate column 2, and a collection column 3 from top to bottom; the upper end of the cylinder 31 of the collection column 3 There is a threaded port for threaded connection with the middle column 2 or the protective column 1. The middle column 2 is made of stainless steel, which can meet the monitoring work of shallow groundwater and the material cost is moderate. The inner walls of the upper and lower ends of the middle column 2 are uniform. There are threads for threaded connection with the protective column 1 and the collection column 3. The protective column 1 is a cylindrical cover with a threaded opening, which is assembled by the detachable way of the protective column 1, the middle column 2 and the collection column 3. The intermediate column 2 of different l...

Abstract

The invention discloses a shallow groundwater pollutant monitoring system, comprising: a monitoring well and a sampling assembly, the monitoring well is divided into a protection column, a middle column and a collection column from top to bottom; the upper and lower parts of the collection column are respectively It is a cylinder and a cone, and the wall of the collection column at the lower part of the cylinder is provided with multiple groups of small holes for groundwater infiltration, and the inner wall of the collection column below the small holes is provided with a filter material replacement assembly. The invention is suitable for monitoring the observation index of groundwater quality, especially realizes in-situ monitoring, and reduces the difficulty of sampling under the condition of monitoring shallow groundwater at different depths, and makes the sampling process simple and quick.

Description

technical field [0001] The invention relates to the technical fields of environmental science, groundwater pollution and soil science research, in particular to a shallow groundwater pollutant monitoring system. Background technique [0002] With the development of agricultural modernization, the extensive use of chemical fertilizers and pesticides has become the most important factor of soil environmental pollution. Among them, pesticide residues have seriously affected the water environment. Studies have found that the amount of water-soluble pesticides accounts for more than 50% of the total amount of pesticides. After being applied to paddy fields, they are mostly soluble in paddy water, and easily pollute the water environment through surface runoff and soil leakage. [0003] Shallow groundwater refers to the aquifer within 60 meters below the surface. Due to its shallow buried layer and no deep rock filtration, the water body is easily polluted by sewage discharged f...
