열적방법을 활용한 유기염소계 폐농약의 분해 특성 평가 = Evaluation of Decomposition Characteristics of Organochlorine Pesticides Using Thermal Method

다국어 초록 (Multilingual Abstract)

The Stockholm Convention, which was adopted in Sweden in 2001 to protect human health and the environment,includes regulations for Persistent Organic Pollutant Rotors such as toxic and bioaccumulatives. Currently, there are 28types of materials. This prohibits and limits the production, use, and manufacture of products. Korea is a member of theConvention, and it is necessary to prepare management and treatment plans to address the POP trends. Thus, we experimentallyinvestigate whether the environmentally stable incineration is achieved when the sample is thermally treatedusing the Lab-scale (1 kg/hr). The target samples is pesticides in liquid phase and solid phase. In this study, organic chlorinatedpesticides and their thermal characteristics were analyzed. We calculated the theoretical air volume based on theelement analysis results. Because the interior of the reactor is small, more than 10 times of the air ratio was injected.
The retention time was set to at least 4 seconds using a margin. The incineration temperature was 850oC and 1100oC.
Thus, we experimentally investigated whether the environmentally stable incineration was achieved when the sample wasthermally treated using the Lab-scale (1 kg/hr). We analyzed five types of exhaust gas; the 02 concentration was high,but the CO amount decreased. Complete combustion is difficult because of the small size of the furnace due to the natureof Lab-scale. The organic chlorine-containing pesticide had an average decomposition rate of 99.9935%. Considering thedecomposition rates of organic chlorine-containing pesticide in this study, the incineration treatment at over 2 ton/hour,which is typical for a conventional incinerator, is possible. Considering the occurrence of dioxins and unintentional persistentorganic pollutants, it can operate at more than 1,100oC.
