FIELD: chemical technology.
SUBSTANCE: invention relates to detoxification of polychlorobiphenyls, in particular, the capacitor dielectric liquid Sovtol-10 and can be used in chemical and electrochemical industry effectively. Method for detoxification of polychlorobiphenyls is carried out in mixture with calcium compounds taken in the ratio = 1:(2.6-3.2) or in mixture of polychlorobiphenyls with calcium compounds with addition of chemical reagent taken in the ratio = 1:(1.8-2.2):(0.3-0.5), respectively. Chemical agent represents water-soluble calcium and magnesium sulfoacids. The detoxification process is carried out at temperature 100-120 C. The prepared detoxificated product is treated with bitumen in the ratio = 1:(0.15-0.2). Invention provides explosion-proof and fire-proof, reducing energy consumptions for exploitation and investments for development of manufacture.
EFFECT: improved detoxification method.
