物化-生物组合工艺处理TNT红水
Treatment of TNT red water by physico-chemical and biological technologies
摘要
Abstract
The combination technology of acidification,micro-electrolysis,coagulating sedimentation,vacuum distillation,immobilized micro-organism and adsorption by activated coke (AC) was used to treat TNT red water generated from Xiangfan Division of 805 Factory.After treatment,the concentration of nitro compounds in effluent was lower than 0.8 mg/L,the average concentration of chemical oxygen demand (COD) was 51.6 mg/ L,with the mximum value of 76 mg/L,the chrominance was 20°,and the concentration of aminobenzene was lower than 1 mg/L.The values of these parameters reached the requirement of the factory,which are belowthe limits proposed by Chinese standard GB14470.1-2002 (Discharge Standard for Water Pollutants from Ordnance Industry:Powder and Explosive).During the period of the pilot scale test,the vacuum distillation apparatus operated stably,and no trouble of blocking and burning happened,meaning that treatment of TNT red water by vacuum distillation was safe and reliable.关键词
