Method and apparatus for processing organic chlorine compounds

A method of processing an organic chlorine compound for decomposing and eliminating the organic chlorine compound in an object to be processed,

• said method comprising a biological treatment process of causing a first microorganic body capable of oxidizing reduced nitrogen to come into contact with said object to be processed, and biologically processing said object to be processed in a state containing said first microorganic body, so as to decompose said organic chlorine compound;
• a reduced nitrogen adding process for adding reduced nitrogen to said object to be processed;
• wherein as said first microorganic body and/or a second microorganic body, those in a dehydrated cake form whose moisture is at least partly eliminated or in a lyophilized powder form are used.

• a reduced nitrogen adding process for adding reduced nitrogen to said object to be processed;
• wherein, in said reduced nitrogen adding process and/or reduced nitrogen adding step, reduced nitrogen is added to said object to be processed such that the content of said reduced nitrogen with respect to 1 ng of said organic chlorine compound becomes 0.01 to 10 g-N.

• said method comprising a biological treatment process of causing a first microorganic body capable of oxidizing reduced nitrogen to come into contact with said object to be processed, and biologically processing said object to be processed in a state containing said first microorganic body, so as to decompose said organic chlorine compound,
• wherein said biological treatment process comprises:
• an anaerobic treatment process in which said object to be processed containing said first microorganic body keeping a biological activity thereof by way of a biological treatment in an aerobic atmosphere is held in an anaerobic atmosphere.
