| 摘 要： | 根据清洁生产原理、间二硝基苯生产工艺及废水产生情况,提出了重结晶废水直接回用于精制,精制废水蒸馏后回用于精制洗涤和重结晶的清洁生产工艺;经小试4次和中试3次废水循环套用后产品均为优等品,证明清洁生产工艺对产品质量无不良影响,可实现工艺废水零排放。

| Abstract: | The paper gives a cleaner production process of m-dinitrobenzene by means of cleaner production principle,production process and m-dinitrobenzene production wastewater.The process includes the reuse of recrystallization wastewater to refining and the reuse of refining wastewater to leaching and recrystallization after distillation.After 4 times of benchscale testing and 3 times of pilotscale testing,all of the products are premium grade.It demonstrates that the cleaner production process is not harmful to p... |
