| 摘 要： | INTRODUCTIONDioxin is an appellation for a series of organic compounds containing chlorine one or two benzene rings 1]. Because the substituted position of chlorine atom is different between 1 and 9, 75 kinds of isomers of PCDD(polychlorinated dibenzo-p-dioxins)and 135 kinds of PCDF(polychlorinated dibenzofurans)are composed, which are generally entitled as dioxin. Among these isomers, there are 17 kinds (position 2, 3, 7, 8 replaced by chlorine atoms) are considered to be the most ha…

| Abstract: | Dioxins are believed the most poisonous compounds in the world. Dioxin pollution is a strategic problem in papermaking industry which must be solved. Dioxin not only exists in pulp, paper products, but also in the volatile of woods, hips or other non-wood fiber material which are treated with PCP, even in the exhaust gas of chemical recovery system. So there are great needs to know what is dioxin, the channel and mechanism of the formation of it in paper making industry. With these understanding, herein those are discussed as follows, the harness measure of dioxin: dioxin in wastewater, in exhaust gas, from raw material. And some countermeasure to decrease the content of dioxin. Furthermore, several novel treatment technologies of dioxin in China and abroad were introduced. The fundamental measure to eliminate the pollution of dioxin is presented with the aim to control the origin, decrease the use of bleacher containing chlorine or without the use of chlorine. Elemental Chlorine Free and Total Chlorine Free bleaching are advocated. |
