Detailed Description
Other aspects, features and advantages of the present invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, which form a part of this specification, and which illustrate, by way of example, the principles of the utility model. In the referenced drawings, the same or similar components in different drawings are denoted by the same reference numerals.
As shown in figure 1, the application provides a tunnel wastewater treatment integrated inclined tube sedimentation tank, and the arrow direction shown in the figure is the flow direction of water flow in the wastewater purification treatment process.
The tunnel wastewater treatment integrated inclined tube sedimentation tank comprises an inclined tube sedimentation tank 3 which is manufactured by welding carbon steel, a sludge storage hopper 7, a water distribution area 4, an inclined tube area 5 and a clear water area 6 are sequentially arranged in the inclined tube sedimentation tank 3 from bottom to top, a plurality of water collecting tanks 10 are arranged on the clear water area 6, the number of the water collecting tanks 10 is determined according to the size of the inclined tube sedimentation tank 3 or the clear water area 6, and each water collecting tank 10 is provided with a plurality of weir mouths.
