A river channel environmental protection dredging and mobile sludge concentration and dewatering system

Abstract

The invention belongs to the technical field of environment friendliness, relates to a sludge treatment process system and in particular relates to an environment-friendly riverway dredging and movable sludge concentrating and dewatering system. The environment-friendly riverway dredging and movable sludge concentrating and dewatering system is composed of an environment-friendly dredging unit, apretreatment unit, a sludge concentrating unit, a sludge conditioning unit and a sludge dewatering unit which are sequentially connected by pipelines. Riverway sludge is pumped on the pretreatment unit on the shore by the environment-friendly dredging unit in a riverway and is concentrated by the sludge concentrating unit after large-particle garbage and suspended matters are removed, so that theconcentration of the sludge is further increased; then, the riverway sludge is delivered into the sludge dewatering unit for dewatering after being homogenized and conditioned by the sludge conditioning unit; and finally, the conversion from the riverway sludge to clear water and mud cakes is finished. The system realizes the online flow operation of dredging, conveying and treatment of the riverway sludge; and meanwhile, the system has the characteristics such as good environment-friendly dredging effect, short process flow, high integration level and good movability.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a sludge treatment process system, in particular to a river channel environmental protection dredging and mobile sludge concentration and dewatering system. Background technique [0002] In recent years, with the rapid development of urban construction and the increase of population, river pollution has become increasingly serious, and its water quality has become worse and worse, seriously affecting the image of the city. There are many reasons for the deterioration of river water quality, the most important of which is the accumulation and thickening of the silt layer at the bottom of the river. Because the silt layer contains a large amount of organic matter, it often causes problems such as black odor and blue-green algae in the river. [0003] At present, there are three methods of river dredging, namely drain dredging, underwater dredging and environmental dr...

AI Technical Summary

Problems solved by technology

At present, the commonly used river dredging sludge is treated in a centralized manner, which requires a large site to build sludge treatment facilities

It is generally difficult to find such a site around the river. Sludge treatment facilities are often built far away from the river. Sludge needs to be transported to the treatment site for a long distance, either by pipeline or by car, which increases a lot. delivery cost

Moreover, if the river dredging sludge adopts the traditional sludge treatment method, there are disadvantages such as complicated process, difficult operation and management, high treatment cost, and secondary environmental pollution.
