Abstract


Nitrobenzene, aniline wastewater has significant toxicity , especially its \between nitro phenol and o- aminophenol and p-nitrophenol . Its more toxic than aniline 60 times larger , can be oxidized or the complex hemoglobin, destruction of the blood circulation and the nervous system , the light sensory loss of normal function and cause anemia , severe cases can lead to death , nitrobenzene in aqueous solution by adsorption or the food chain into the the human body. U.S. Environmental Protection Agency regulations, nitrobenzene, 2,4 - dinitrotoluene , 2,6 - dinitro toluene nitroaromatic priority control monitoring of pollutants ; China 's State Environmental Protection Administration has nitro benzene included 70 list of priority pollutants . Nitroaromatic detection rate and concentration of nitrobenzene in China 's Songhua River and other rivers are high, rivers trace organic pollutants . This article has a high concentration of nitrobenzene , aniline pollution of groundwater for the study, the new penetrating chemical reaction well group to study the removal of nitrobenzene , aniline contaminated groundwater methods and mechanism to deal with the high concentration of nitrobenzene in the underground environment aniline contaminated water to provide a theoretical basis . Saturated water during the experiment , the first analog groove chemical reaction wells arranged in quincunx , according to the experimental design , well group to form a chemical reaction , packed in the simulated slot provided in each reaction well after the sampling point . Then , according to the experimental data and simulation glass column group of chemical reaction wells to restore the performance parameters of the medium , one by one to determine the actual flow of the indoor simulation tank water body , the Darcy velocity and sand permeability coefficient . Finally, the best parameters of the chemical reaction well group the bimetal also in raw materials , as well as chemical reactions well group in the optimum conditions of nitrobenzene , aniline treatment effect.
