<p>A method for regenerating activated coke used for treating wastewater or sewage is provided, which comprises feeding the activated coke to a space at a temperature of 150~250 °C; heating the activated coke to a temperature of 700~850 °C for 40~90 minutes; feeding steam to the space in the quantity of 0.1~0.5 m3/t activated coke; the exhaust gas from heating the activated coke flowing in counter current with cooling water; cycling condensation water from the steam of the exhaust gas; and using the other paraffin gas as a fuel. An apparatus for regenerating activated coke is also provided, which comprises setting a heatingchamber (63) within a combustion chamber (15); connecting two ends of the heating chamber (63) to a gas collecting chamber (20) with an inlet pipe (8) and to a discharging chamber (1) with an outlet pipe (12) respectively; setting a gearing (35) for driving the heating chamber(63); connecting a steam inlet (5) of the discharging chamber (1) to a steam outlet (62) of a steam device (60); and setting an exhaust gas outlet (22) in the upper portion of the outer wall of the gas collecting chamber (20), a screw conveyer (37) on the top of the gas collecting chamber (20), a feeding storage (38) in the upper portion of the screw conveyer (37), and the exhaust gas outlet (22) connecting to a gas inlet (42) of a washing tower (39).</p> |
