A Preliminary Study on Dewatered Municipal Sludge Treated By Microwave
A new method to treat four solid wastes of dewatered municipal sludge,sodium silicate used sands, clay sands sludge and waste polyethylene, was discussed.About wt 50.0 % sodium silicate used sands and wt 50.0 % dewatered sludge were mixed, and then cured by microwave with a certain thickness film of clay sands sludge and waste plastic of polyethylene in the surface.The results showed that the compression strength of granulation sample with the size of Φ 50 × 50 mm was over0.45 MPa.The waste plastic was another key factor for the durability, and curing temperature must be over melting temperature, so the thicker film could be coated in the surface of used sands and sludge.
