Laboratory simulation device for groundwater pollution remediation and usage method of laboratory simulation device

Abstract

An embodiment of the invention provides a laboratory simulation device for groundwater pollution remediation and a usage method of the laboratory simulation device. The device comprises a simulation aquifer unit, a water pumping and distributing unit, a remediation unit, an air stripping unit and a monitoring unit, wherein water is delivered to a simulation aquifer through a first peristaltic pump by a water storage barrel; a water pumping well and a water pumping pipe are communicated with the simulation aquifer and the outside, a sieve pipe is located below the water level of the simulation aquifer, and a water intake port of the water pumping pipe is located at the lower part of the sieve pipe; a second peristaltic pump is communicated with the water pumping pipe and a water guide pipe, and the other end of the water guide pipe is connected with a T-shaped water distributing pipe; the bottom of a seepage zone is communicated with the simulation aquifer; a water flow flows in filler layers of the seepage zone and a reaction zone in an S shape; multiple air guide pipes capable of being closed are distributed in an overlaying soil layer; an aeration fan is connected with one end of an air delivery pipe, and the other end of the air delivery pipe extends below the water level of a water layer of the water pumping well; multiple air pumping wells are communicated with the simulation aquifer and the outside and connected with an air pump; the monitoring unit comprises multiple sampling pipes which are located at the simulation aquifer, the reaction zone and the seepage zone respectively.

Description

technical field [0001] The invention relates to the technical field of groundwater pollution restoration in environmental protection, in particular to a laboratory simulation device for groundwater pollution restoration and a use method thereof. Background technique [0002] Groundwater is a precious resource that human beings rely on for survival. Since entering the industrialized society, groundwater, which is an important water supply source for urban and rural areas, has been affected by human activities, and a large number of pollutants have entered the groundwater environment, making the groundwater inevitably polluted, and the pollution is increasing year by year. . In view of the seriousness of groundwater pollution, people have invested a lot of manpower and material resources in the research of contaminated groundwater remediation technology. It is one of the important means to study such scientific issues by building an experimental device that simulates the grou...

Problems solved by technology

Similarly, the existing trough experiments can only simulate one repair technology alone. When simulating another repair technology, it is necessary to re-arrange various repair components, and even redesign the filling medium material, which virtually increases the workload of scientific researchers. Reduce workload and work cost, reduce work efficiency
