利用Fenton试剂预处理间二硝基苯生产废水 总被引:16,自引:2,他引:16
间二硝基苯生产废水中含有大量的硝基苯类衍生物,对生物具有毒性,属难生物降解类化合物,本研究利用芬顿试剂对该废水进行处理,废水的CODCr、硝基苯含量(NB)及色度的去除率分别达到60%、88%和82%以上,废水的可生化性得到较大幅度的提高,为后续处理创造了条件。 相似文献

On March 21, in Xiangshui County, Yancheng city, China, a catastrophic explosion occurred at Tianjiayi Chemical Co., Ltd. that caused 78 deaths and injured more than 617 individuals, with a property loss of as much as US$ 100 million. An explosion crater with a diameter of 98 m was generated. An extensive consequence analysis based on the crater size and physical effects for the estimation of the quantity of exploded dinitrobenzene (DNB) was performed. By using the position recorded in the satellite photo and the layout of the plant, the crater site was determined to be located near a warehouse where dinitrobenzene was stored. From the scaling law associating the TNT equivalent with crater diameter, the TNT equivalent of exploded ditrobenzene was determined to be approximately 708 tons. Based on the results of the consequence analysis performed by three methodologies, it can be concluded that the Tianjiayi Chemical Co. warehouse not only stored a substantially large quantity of dinitrobenzene but was also located too close to adjacent structures without an adequate separation distance. Judging by the effect of explosive blast on personnel, a fatality radius was determined to be about 400 m from the explosion center. 相似文献
