Description

Technical Field

[0001] The utility model relates to the technical field of slurry shield machine construction, in particular to a slurry shield waste slurry processing device based on magnetic flocculation. Background Art

[0002] In the construction of modern urban underground transportation, water conservancy tunnels and urban public facilities, the shield method is widely used due to its advantages such as less impact on the environment and fast construction speed. During the shield construction process, in order to maintain the stability of the shield machine's working face and the solidification of the tunnel wall, a large amount of mud and water will be used to balance the stratum pressure, which will produce a large amount of waste mud. If these waste muds are not properly handled, they will cause serious pollution to the environment, such as groundwater pollution and soil pollution. Therefore, it is particularly important to develop an efficient and environmentally friendly mud shield waste mud treatment device. As an emerging water treatment technology, magnetic flocculation technology uses the action of a magnetic field to make magnetic or magnetizable floccules quickly aggregate and settle, thereby quickly separating clean water. This technology has the characteristics of high treatment efficiency, small equipment footprint, simple operation and low energy consumption. Applying magnetic flocculation technology to the treatment of waste slurry from slurry shields can effectively remove pollutants such as suspended particles, organic matter and heavy metals in the slurry, and achieve the reduction, resource utilization and harmless treatment of the slurry. At present, although there are some water treatment devices based on magnetic flocculation technology, these devices are mostly aimed at industrial wastewater, domestic sewage and other fields. The treatment devices specially designed for the characteristics of waste slurry from slurry shields are not yet mature. Therefore, the development of a slurry shield waste slurry treatment device based on magnetic flocculation technology can effectively solve the problems of low treatment efficiency, complex equipment, high cost and environmental pollution in the existing technology, which is of great significance for promoting the environmentally friendly development of shield construction.
