System for detoxification of toxic organic chlorinated compound and method of recycling the detoxified waste

A system for detoxification of a toxic organic chlorinated compound, the system comprising:

• a detoxification process unit for decomposing said toxic organic chlorinated compound into a harmless organic compound by adding an additive including hydrogen donor, alkaline substance and precious metal catalyst to the toxic organic chlorinated compound stored in a container or included in a device, thereby to obtain a harmless products;
• a distillation unit, which is installed in said detoxification process unit, for distilling a processed oil obtained by the detoxification process at the detoxification process unit, thereby to recover a hydrogen donor;
• and
• a recycle line for supplying said hydrogen donor to the detoxification process unit so that the hydrogen donor is reused in the detoxification process for the toxic organic chlorinated compound, and for supplying the processed oil, from which the hydrogen donor is removed or a fractionally separated oil, to an user so that the oil is reused as a material for chemical industrial products.

• a distillation unit, which is installed in said detoxification process unit, for distilling a processed oil obtained by the detoxification process at the detoxification process unit, thereby to recover a hydrogen donor;
• an incineration unit for incinerating the processed oil from which the hydrogen donor is removed, thereby to generate exhaust heat;
• and
• a recycle line for supplying said hydrogen donor separated and recovered at the distillation unit to the detoxification process unit so that the hydrogen donor is reused in the detoxification process for the toxic organic chlorinated compound, and for supplying the exhaust heat generated at the incineration unit to an user.

A method of recycling a detoxified waste comprising the steps of:

• adding an additive including hydrogen donor, alkaline substance and precious metal catalyst to a toxic organic chlorinated compound;
• decomposing said toxic organic chlorinated compound into a harmless organic compound thereby to provide harmless products;
• and
• recycling the products by utilizing at least one processing method selected from the group consisting of:
• (1) a processing method in which a non-reacted hydrogen donor is recovered from a processed oil as the products obtained from the decomposing process, and the non-reacted hydrogen donor is reused as a material for decomposing the toxic organic chlorinated compound;
• (2) a processing method in which a waste oil produced by removing hydrogen donor from the processed oil obtained from the decomposing process is reused as a material of chemical industrial products;
• or the waste oil or an oil produced by removing valuable resource from the waste oil is incinerated and the exhausted heat is utilized as a heat resource;
• (3) a processing method in which a precious metal catalyst used at the decomposing process is regenerated and the regenerated precious metal catalyst is reused as a material for decomposing the toxic organic chlorinated compound;
• and
• (4) a processing method in which a salt obtained from the decomposing process is regenerated into an alkaline substance and the regenerated alkaline substance is reused as a material for decomposing the toxic organic chlorinated compound.

A method of recycling a detoxified waste, comprising the steps of:

• adding an additive including hydrogen donor, alkaline substance and precious metal catalyst to a toxic organic chlorinated compound stored in a container or included in a waste device;
• decomposing the toxic organic chlorinated compound into a harmless organic compound;
• detoxifying at least one organic substance selected from the group consisting of waste cloth, plastic bag, paper and timber used in said decomposing process of the toxic organic chlorinated compound;
• applying a reduction process to the detoxified organic substance thereby to produce a reducer, and utilizing the reducer;
• detoxifying a metal member generated at a time of scrapping the container or the waste device, and melting and regenerating the detoxified metal member, thereby to utilize the regenerated metal member as a raw metal material.
