[Technology] PRB technology advantages and disadvantages
PRB technology refers to the underground installation of active material wall in order to intercept the contaminant plume so that contaminated plume through the reaction medium, the pollutants can be transformed into another form accepted by the environment, so as to achieve the concentration of pollutants The goal of environmental standards. The PRB consists of a permeable reaction medium, which is usually placed downstream of a plume polluted by groundwater. When the polluted groundwater passes through the PRB, pollutants in the water are removed by sedimentation, adsorption, redox, etc. to obtain a clean groundwater. Removal of dissolved organic matter, metals, radioactive materials and other pollutants. PRB technology is an important method of remediation of contaminated soils and groundwater in the world at present, with unique advantages unmatched by other technologies. Compared with the traditional pollution of groundwater treatment technology, this technology is a passive system without external power. The operation of the treatment system is underground and does not occupy PRB in the surface area. Once installed, virtually no additional operating and maintenance costs are required except for the need to replace the wall reaction material in some cases. PRB is a popular treatment method of groundwater pollution in recent years. It has the advantages of continuous treatment of various pollutants in situ, good treatment effect, convenient installation and construction, and high cost performance.
