Integrated treatment method for treating dredging sludge in rivers and lakes

Abstract

The invention relates to an integrated treatment method for treating dredging sludge in rivers and lakes. The integrated treatment method for treating dredging sludge in rivers and lakes is used. Theintegrated treatment method for treating dredging sludge in rivers and lakes comprises a belt type conveying frame, a stirring device and a drying device. The stirring device is mounted at the rear end of the belt type conveying frame; the drying device is arranged on the right side of the stirring device; the lower end of the drying device is connected with the upper end of the belt type conveying frame. According to the integrated treatment method for treating dredging sludge in rivers and lakes, sludge treatment is carried out by adopting a design concept of a stirring-vibration flattening-drying integrated mechanical operation structure so that the working efficiency is greatly improved, and the labor intensity of workers is reduced; meanwhile, a cleaning mechanism capable of treatingscattered sludge in time is arranged, and a structure of firstly centralized storage and then centralized cleaning is adopted for the cleaned residual sludge so that the cleaning degree of the surfaceof the equipment is improved, and the probability that the sludge is dried up and accumulated on the surface of the equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of river cleaning, in particular to an integrated treatment method for river and lake dredging sludge. Background technique [0002] Silt is a kind of soft soil with a natural water content greater than the fluidity limit and a void ratio greater than 1.5. It is a modern sediment formed under the condition of microorganisms participating in the environment of slow water flow in bays, lakes or river bends. It is rich in organic matter, often gray-black in color, low in mechanical strength, and strong in compressibility. If there is sludge in the foundation, it is easy to cause the building to subside. In my country, domestic sewage in coastal cities is mostly discharged into the deep sea through culverts, while sewage in inland cities can only be transported to sewage treatment plants through underground pipe networks, and then discharged into rivers after treatment. However, sometimes the sewage pumps are out...

Problems solved by technology

[0003] 1. There are many kinds of impurities in the sludge. When the sludge is directly dried, some impurities are prone to remain in their original state due to their excessive volume or hardness. These impurities cannot be used for subsequent reuse. For example, when used as a fertilizer, the sludge that has been stirred and dispersed is prone to uneven thickness when it is placed in a holding tool, and then in the subsequent drying process, it is prone to the phenomenon that the evaporation and drying speed is inconsistent, that is, some parts appear T
