Title: Replacing method of activated carbon in activated carbon treatment apparatus
Inventor: DAISHIN NORIKO
IPC: B01D15/00
Filed: 1999-07-15
Abstract: PROBLEM TO BE SOLVED: To prevent the lowering of the treatment capacity of org. matter immediately after the replacement of activated carbon. SOLUTION: Water containing an oxidizing agent (e.g.; hydrogen peroxide) and org. matter (e.g.; choline) is treated in an activated carbon treatment apparatus. At first, 'water passing treatment' and 'back washing treatment' at every constant period are repeated in the activated carbon treatment apparatus. When an activated carbon replacing period comes, 'replacement of activated carbon' is performed but, at this time, the whole amt. of activated carbon is not replaced and a part thereof is left. By this constitution, the removal of org. matter by biological activated carbon can be performed just after replacement.
