[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Figure 1 This is a schematic diagram of the waste treatment device with a multi-channel feeding method according to the present invention.

[0019] Please see Figure 1The waste treatment device with multi-channel feeding provided by this utility model includes a rotary kiln 7 and a secondary combustion chamber 8. The outlet of the rotary kiln 7 is connected to the inlet of the secondary combustion chamber 8. The device also includes a first solid waste feeding channel 1, a second solid waste feeding channel 2, a side gate waste feeding channel 3, a waste liquid feeding channel 4, and a waste gas feeding channel 5. A feeder 6 is provided at the inlet of the rotary kiln 7, and liquid spray guns are provided on the rotary kiln 7 and the secondary combustion chamber 8. The first solid waste feeding channel 1, the second solid waste feeding channel 2, and the side gate waste feeding channel 3 are connected to the feeder 6 or the rotary kiln 7.
