Integrated analog device and method for groundwater pollution process and pollution remediation

Abstract

The invention discloses an integrated analog device for groundwater pollution process and pollution remediation. The integrated analog device comprises an analog tank, wherein the analog tank is divided into a front part box and a rear part box, one side of each of the front part box and the rear part box is an open end, a permeable reactive barrier is arranged between the open ends of the two boxes, and two side surfaces, corresponding to the open ends of the two boxes, of the permeable reactive barrier are provided with vertically arranged sampling holes; the open ends of the two boxes are concave troughs, and a blocking plate is made of draw-out and insertion steel; the side walls on two sides of the analog tank are respectively provided with sampling holes and monitoring holes; the other sides of the two boxes are respectively provided with an upstream water tank and a downstream water tank, and a porous plate is respectively arranged between the upstream water tank and the boxes and between the downstream water tank and the boxes; and the bottom part of the outer side wall of the upstream water tank is provided with a water inlet hole, the outer side wall of the downstream water tank is provided with vertically arranged overflow holes at different heights, and a water stop valve is arranged at the bottom part of the outer side wall of the downstream water tank. The invention also discloses a method for using the device.

Description

technical field [0001] The invention belongs to the field of environmental simulation technology research, and more specifically relates to an integrated simulation device for simulating groundwater pollution process and pollution restoration. [0002] The invention also relates to a method of use of the above device. Background technique [0003] As an important water source for urban and rural water supply, groundwater plays an irreplaceable role in maintaining the healthy development of the economy and society. However, due to the impact of human activities, a large number of pollutants enter the groundwater environment, causing the problem of groundwater pollution to become increasingly serious. Therefore, for many years, many scientific researchers have been engaged in the scientific research of groundwater pollution prevention and control. An important means to study such scientific issues is to build an experimental device to simulate the groundwater environment, and...

Problems solved by technology

[0004] The study found that there are some shortcomings in today's groundwater physical simulation devices: First, the small simulation devices used in the laboratory, such as soil columns or small simulation tanks, are simple to operate, easy to replace media materials and low in cost, but the groundwater environment The complexity of these devices makes it difficult to simulate the real groundwater environment

However, after the pollution remediation process, especially the PRB remediation t
