Embodiment 1

[0024] Embodiment 1: In order to use the present invention to carry out the penetration test of conservative solutes, to further describe the implementation effect of the present invention. Such as figure 1 The N types of solutions for penetration are prepared in advance, and the multi-channel peristaltic pump 2 is connected with a hose, the outlet of the multi-channel peristaltic pump 2 is connected to the integrated sensor 4 through the hose, and then connected to the installed packing column 5, Put the packing column 5 on the base, clamp the middle and lower part with a vibration handle, connect the water outlet of the packing column 5 to the integrated sensor 4, and then connect part of the collector 6 through a hose, and finally all the electrical equipment (including multi-channel peristaltic Pump 2, sensor 4 and online real-time monitoring system 8) Connect to the control center (computer) 1 for plug-in installation and control, and finally activate the power supply. D...

Embodiment 2

[0025] Embodiment 2: In order to use the present invention to carry out the comparison of the automatic pollutant penetration and online real-time monitoring experiment under the alternate penetration of fresh water and sea water under the condition of saturation of the salty and fresh water interface in coastal areas and the time saving under manual operation in ordinary laboratories. The control center of the invention can realize the parameter setting of equipment and instruments without manual debugging one by one; the multi-channel peristaltic pump can save the time for manual replacement of the target solution, and realize the seamless switching of fresh water and salt water penetration, reducing errors; Integrated sensors are installed to directly save the time for manually measuring the pH value, conductivity and other parameters of samples one by one, and realize continuous and uninterrupted measurement of parameters, avoiding the discontinuity and jump of manual measur...

Abstract

The invention relates to an experimental system for intelligent penetration sampling and on-line monitoring for soil and underground water pollutants. The system comprises a system control center, a peristaltic pump, integrated transducers, an electromagnetic vibration handle, a filler column, a fraction collector, an on-line real-time monitoring system and other connecting devices or containers. A computer is adopted as the control center. The multi-path peristaltic pump can control a plurality of water feeding hoses. Inlet and outlet ends of the filler column are provided with the integrated transducers. The fraction collector collects a certain amount of samples at regular time. The on-line real-time monitoring system can measure system critical parameters. A pollutant penetrating device provided by the invention can stimulate complex reaction situations and macroscopic and microcosmic migration mechanisms among pollutants, colloid and solid-phase media in saturated or unsaturated soil and underground water, and performs qualitative and quantitative analysis and completes mapping of related graphs and charts through monitoring in real time chemical and physical properties of a target solution before and after penetrating the filler column and monitoring critical parameters of a filtrate liquid after penetration. Measurement is convenient and easy in operation.

Description

technical field [0001] The invention relates to an experimental system for intelligent sampling and on-line monitoring of soil and groundwater pollutant penetration, especially an experiment for colloid to promote pollutant migration under complex hydrogeological conditions. Background technique [0002] At present, all countries in the world attach great importance to the problem of groundwater pollution, and problems caused by groundwater pollution occur frequently. This problem is more prominent in China, and about 70% of the population in my country uses groundwater as the main drinking water source. Therefore, the study of the migration law of pollutants in groundwater and its influencing factors is helpful for the prediction of groundwater pollution and risk assessment. pollution control. The present invention takes this as a starting point to simulate the migration of pollutants in the submerged layer, especially the migration rule under the influence of colloid, by d...
