Abstract
The invention relates to a method for in-situ restoration of nitrobenzene-polluted underground water through a nano-iron slurry reaction zone. More than one injection well and observation well are dub in an underground pollution area, nano-iron slurry or starch modified nano-iron slurry which is well prepared in advance is filled in the injection well, a target pollutant in the observation well needs to be monitored in a real-time manner during filling, and the filling is stopped when achieving the desired treatment effect. The target pollutant of nitrobenzene is converted to aniline which is easy to biodegrade, the conversion rate is greater than 95%, and other long-chain organic pollutants which are difficult to degrade can also be converted to short-chain organic matters which are relatively easy to biodegrade; the reaction region is in an alkaline anaerobic environment, thereby being conductive to growth of anaerobic microorganisms; the prepared nano-iron slurry and the starch modified nano-iron slurry have larger specific surface area, and can greatly adsorb and intercept other impurities in the underground water; the method has no secondary pollution, greenness, environmental protection, low cost, convenient maintenance, low maintenance cost and convenient operation and running management; and the treatment of the target pollutant is direct, fast and high in efficiency.
