Abstract

The invention relates to an oxidation treatment device of solid wastes containing toxic organic matters, belonging to the technical field of environment-protection devices. The oxidation treatment device is characterized in that the upper part of a reaction device (1) is provided with a sample inlet pipe (2) and a gas inlet pipe (3); the gas inlet pipe (3) is connected with an annular gas distribution pipe (4) positioned at the bottom inside the reaction device (1); the reaction device (1) is internally provided with a pH couple (5), a temperature couple (6), a turbo type stirrer (7), a heating device (8) and a condenser pipe (11); a sampling opening (9) of the reaction device (1) is positioned at the bottom of the reaction device (1); an exhaust pipe (10) is positioned at the upper part of the reaction device (1); and the gas inlet pipe (3) and the exhaust pipe (10) are provided with switches. The invention can efficiently promote a liquid or gas oxidant to be fast and uniformly mixed with the solid wastes, ensures the safety of an oxidative degradation process, has high reaction efficiency, furthest prevents the secondary pollution and can be used for the fields of the emergency treatment of hazardous wastes containing the toxic organic matters under the condition of sudden accidents, the landfill pretreatment of the hazardous wastes, and the like.

Description

technical field [0001] The utility model relates to an oxidation treatment device for solid waste containing toxic organic matter, which belongs to the technical field of environmental protection devices. Background technique [0002] Hazardous wastes containing toxic organic substances refer to hazardous wastes that are based on clay-like inorganic substances but characterized by small amounts of toxic organic substances. They are mainly produced in petroleum, petrochemical, chemical and other industries. Seriously, the reserves of applicable treatment technologies are insufficient, and the wastes with a low rate of innocuous treatment. Due to the large output, low calorific value, and mainly inorganic substances, this kind of waste is mostly disposed of by landfill in practice. In view of the fact that my country's current hazardous waste identification standards lack indicators of toxic organic substances, if such hazardous waste is directly landfilled without treatment,...
