Embodiment 2
[0051] The difference from Example 1 is that the waterworks sludge with a water content of 65% is selected, and a 2450MHz microwave source is used to work continuously, and the sludge is 12.2 cm thick (approximately equal to 3 × 10 8 / 2450MHz) cake shape, microwave power 1.0 kg water / electricity conversion, can be dried to 35% water content.
Embodiment 3
[0053] The difference from Example 1 is that electroplating sludge with a moisture content of 65% is selected, and a 915MHz microwave source is used for continuous operation. The sludge is 32.8 cm thick (approximately equal to 3×10 8 / 915MHz), the microwave power is 1.2 kg of water / electricity conversion, and can be dried to 30% water content.
