Sludge drying treatment device for industrial sewage and wastewater treatment plant, and using method thereof

Abstract

The invention provides a sludge drying treatment device for an industrial sewage and wastewater treatment plant, and a using method thereof. The sludge drying treatment device for the industrial sewage and wastewater treatment plant comprises a sludge dewatering machine and a bottom plate, supporting plates are fixedly connected to two sides of the top of the bottom plate, a drying box is fixedlyconnected between the facing sides of the two supporting plates, a feeding bucket penetrates through one side of the top of the drying box, and the feeding bucket is located under the discharging portof the sludge dewatering machine. Heating columns are mounted according to the actual drying condition, the using number of the heating columns can be controlled to regulate the temperature of heating air; and after the heating columns are mounted, extrusion plates are extruded through the elastic force of springs, the extrusion plates extrude fixing plates through extrusion rods, and the heatingcolumns are fixed through two fixing plates, so the stability of the heating columns is guaranteed, different drying requirements are met, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the field of sludge drying, in particular to a sludge drying treatment device of an industrial sewage treatment plant and a method for using the same. Background technique [0002] In recent years, under the influence of the country's active fiscal policy of energy conservation and emission reduction, cities across the country have vigorously built sewage treatment plants, the construction of urban and industrial sewage and wastewater treatment facilities has developed rapidly, and water environment governance has achieved remarkable results. While obtaining these policies, how to deal with the large amount of sludge generated by sewage treatment plants has become an increasingly prominent problem. According to the data of the National Water Network, by the end of 2010, the national urban sewage treatment volume reached 34.3 billion cubic meters, The production of dewatered sludge is close to 22 million tons, which is a very la...

Problems solved by technology

[0005] The invention provides a sludge drying treatment device for industrial sewage and wastewater treatment plants and its use method, which solves the problem that the existing sludge drying equipment cannot be adjusted according to the actual drying demand when it is used. The temperature of the medium has poor versatility, and the heat in the heat medium cannot be recycled, which increases the problem of energy loss
