Study On Wastewater Treatment Technology Of High Concentration Explosive

At present,In the domestic high fire explosive wastewater treatment industry,Main processing with small molecular HMX elemental explosive wastewater.high acidity and high concentrations of pollutants,due to their pyridine,pyrazine,ammonium ion and chloride ion and inorganic salts and other organic groups.At present,the explosive wastewater treatment technology in China is relatively backward.The traditional physical and chemical methods cannot degrade COD in the wastewater to the national discharge standard.Moreover,the high concentration of COD in the wastewater and complex structure of nitrate content may seriously destroy the biochemical process if the initial wastewater discharged in the system..In this paper,the removal rate of various pollutants in wastewater was increased using fenton reagent method together with ozone oxidation method as the core of innovative experiment to handle the high concentration of HMX wastewater.Chemical method combined with ozone oxidation fenton reagent oxidation phase concentration on average removal rate of COD is about39.2%,Ozone oxidation phase concentration on average removal rate of COD is about 42.3%,is the core of the concentration of COD in waste water treatment process.At the same time,Joint method for the total removal rate of COD concentration in the wastewater is 72.1%,Nitrobenzene class material removal rate is 50.1%,nitrate amine material removal rate is 80.4%,the concentration of the suspended solids removal rate of 76.7%.COD concentration was reduced below 5000 mg/L by cyclic catalysis together with oxidation pretreatment.Moreover,COD,ammonia nitrogen and chromaticity in the wastewater could also be controlled by the hydrogen peroxide solution in the ozone oxidation tower.This method can be used in other explosive factories.
