Abstract


In the \(PCDD_s), polychlorinated dibenzofurans (PCDFs), hexachlorobenzene (HCB) and polychlorinated biphenyls (PCBs). In addition to these four substances with a long residual , bioaccumulative , semi -volatile and highly toxic , but also has the characteristics of unintentionally produced , can not be produced by an ordinary forbidden and prohibited methods to control . According to the requirements of Article V of the Convention , Parties must take measures to reduce and control emissions from the UP-POP_s , first and foremost task is the preparation of emission inventories scientific grasp emissions baseline conditions . April 2007 , our country to the \But so far no other two UP-POP_s (HCB and PCBs) emissions inventory . In order to determine the emissions of HCB and PCBs , this article refer to the Japanese Ministry of the Environment based on measured data compiled emission factors calculated with 2008 as the base year of China's major sources of emissions of unintentionally produced HCB and PCBs in atmospheric emissions inventory , analyze an important source of emissions trends. Scale waste incineration industry has developed rapidly , UP-POP_s expected to become an important source of emissions. This paper selected waste incineration industry as a further object of study, monitored the typical life of a domestic waste incinerator fly ash and flue gas emissions UP-POP_s case analysis of its emission characteristics . Given waste incineration industry is a potentially important source of UP-POP_s need to develop appropriate emission control technology . Degradation of technology can completely decompose gaseous organic pollutants , in order to study degradation technique UP-POP_s degradation effect , we design and produce a solid waste incineration can be used to simulate smoke UP-POP_s degradation of small test reactors, through a series of performance test , the reactor can generate stable HCB concentration 10 ~ 100 ug / L in a mixed gas , and to effects of temperature , flow rate and other factors influence the catalytic reaction , to carry out the subsequent incineration flue uP- POP_s degradation created experimental conditions .
