Description

Technical Field

[0001] The utility model relates to the technical field of tunnel wastewater treatment, and more specifically, to integrated tunnel wastewater treatment equipment. Background Art

[0002] Tunnels provide underground passages for ground traffic, especially in cities, which can ease the pressure of ground traffic, solve the restrictions of topography on the layout of traffic routes, and realize rapid connection between regions. A large amount of wastewater will be generated during the construction of tunnels. These wastewaters will be mixed with a large amount of sludge, cement mortar and other substances, which need to be treated by wastewater treatment equipment. Existing road wastewater treatment equipment can usually only be set up with structures such as sedimentation and filtration, but engineering machinery often misses oil pollution during the excavation process, which is usually impossible to remove by sedimentation and filtration, thereby reducing the effect of tunnel wastewater treatment, so that the treated wastewater still contains oil pollution, which is not conducive to subsequent use; secondly, when the existing road wastewater treatment equipment filters the wastewater, the filter plate is easily blocked by sludge, cement mortar and other substances, which affects the normal filtration of the wastewater and reduces the efficiency of tunnel wastewater treatment.
