Description

Technical Field

[0001] The utility model belongs to the technical field of wastewater treatment, and in particular relates to a shield tunneling mud-containing wastewater treatment device. Background Art

[0002] During the discharge process, the shield tunneling wastewater with mud changes with the changes in production conditions, and there are uneven water quality and unstable water volume. Especially when encountering different rock formations or unstable incoming material sources, the water quality and water volume of the wastewater change more greatly. This change will cause the wastewater treatment process to be abnormal, reduce the treatment effect, and fail to give full play to the design load of the treatment equipment. In order to make the treatment process work normally and not be affected by the changes in the peak flow or peak concentration of the wastewater, it is required that the wastewater has a relatively stable water volume and uniform water quality before treatment, and steady flow regulation of water quality and water volume must be carried out. The setting of a steady flow regulating tank can meet this demand.

[0003] In the existing technology, during the treatment of shield tunneling muddy wastewater, the muddy wastewater directly enters the pool body and reacts fully with the added chemicals, and is easily precipitated at the bottom of the pool to block the pipeline; secondly, since the mud content of the incoming water is uncontrollable, the subsequent addition of chemicals will result in a waste of chemicals when the mud content is small, and the subsequent sedimentation effect will be poor when the mud content is large.
