SLUDGE RECYCLING TREATMENT SYSTEM OF URBAN SEWAGE PLANT

摘要

PROBLEM TO BE SOLVED: To disclose a sludge recycling treatment system of an urban sewage plant which includes solar sludge drying facilities and sludge roasting and activated carbon manufacturing facilities, the solar sludge drying facilities including a sealing box, flat plate conveyor belts, and a conveyor belt traction device, etc., and the sludge roasting and activated carbon manufacturing facilities including a rotary kiln and feeding, conveyor, discharging, and flue gas recycling apparatuses.SOLUTION: The flat plate conveyor according to the present invention are a stepped and concave-convex conveyor manufactured from stainless or anti-corrosion carbon steel. Sludge roasting and activated carbon manufacturing is implemented mainly by a rotary kiln to heat a rotary drum wall therein to heat materials, the kiln having automatic feeding and discharging apparatuses. Harmless treatment and resource utilization of urban sludge converts the sludge from waste to wealth, and fully utilizes solar energy to reduce energy consumption during sludge treatment. During production and operation, no reagent is needed, and no secondary pollution is caused.SELECTED DRAWING: Figure 1
