Technical Field
The utility model relates to a sewage treatment's technical field, concretely relates to week advances week distribution pipe pull throughs who goes out two heavy ponds.
Background
The water inlet and outlet of the peripheral water inlet and outlet secondary sedimentation tank are arranged at the periphery of the tank, the water inlet flows into the water distribution tank at the periphery of the tank firstly, then enters the backflow wall skirt through the water distribution port at the bottom of the tank, falls to the mud surface at the bottom of the tank, flows to the center of the tank, then flows to the water outlet tank at the side of the tank, and is discharged through the water outlet tank. The surface load of the secondary sedimentation tank can be improved when the secondary sedimentation tank is discharged from the secondary sedimentation tank in the periphery under the condition of the same effluent quality.
However, in the actual use process of the circulating inlet and outlet secondary sedimentation tank, the conditions of clogging of the water distribution pipeline and reduction of the effective water distribution area often occur. On one hand, because the biochemical system works for a long time or the grid distance of the front end grating is larger, mixed liquor of the biochemical system contains a certain amount of garbage, and a single water distribution pipeline which enters the periphery and is discharged is far thinner than water distribution pipelines of other forms of secondary sedimentation tanks, so the biochemical system is easy to block; on the other hand, in the long-time operation process, a large amount of sludge and microorganisms are attached to the pipe opening and the pipe wall, so that the effective sectional area of the water distribution pipe is reduced. The water distribution pipeline is silted up or the effective area is reduced to cause that the water distribution of the secondary sedimentation tank is uneven, the effective working area is reduced, the working load of the pipeline which is not silted up is increased, the flow speed in the water distribution pipe is accelerated, the original state of the water flow in the secondary sedimentation tank can be changed, and the impact is caused on the sediment, thereby the water outlet effect is influenced.
