Novel high-density sedimentation tank

Abstract

The invention discloses a new type of high-density sedimentation tank, which comprises a sedimentation tank body, a water collection channel is arranged outside one end of the sedimentation tank body, a number of overflow tanks are arranged in the sedimentation tank body, and the outlet ends of the overflow tanks are connected to each other. To the water collection channel, the overflow tank is arranged in the direction of water flow in the sedimentation tank; in the present invention, the water collection channel is moved outward and arranged on the outside of the sedimentation tank body, so that the effective use area of ​​the inclined plate is increased by more than 15%, and When flushing and maintaining the sloping plate, there will be no dead corners for flushing, which is convenient for maintenance. The peripheral equipment of the collection channel is more conducive to the installation and maintenance of the collection channel. The overflow efficiency of the supernatant of the sedimentation tank is high. The above arrangement will not hinder the flow of water in the sedimentation tank, thus reducing the load on the surface water of the sedimentation tank to the greatest extent. This design is convenient for construction and helps to reduce project investment and construction difficulty.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a novel high-density sedimentation tank. Background technique [0002] Most of the high-density sedimentation tank technologies used in the prior art are imported products. They have been introduced into the sewage treatment field in China and have been used for many years. Generally, all their processes and structures are copied to facilitate construction and use. Such as image 3 with Figure 4 As shown, the water collection channel 2 and the overflow tank 3 are both arranged inside the sedimentation tank body 1, and the water collection channel 2 is arranged in the middle of the sedimentation tank body 1, and the overflow tanks 3 are evenly distributed on both sides of the water collection channel 2, in the direction of the arrow in the figure Indicates the direction of water flow in the sump 2 and the overflow tank 3 . It can be seen that when the water c...

Problems solved by technology

In addition, a sloping plate is installed in the sedimentation tank to settle sludge. After the sedimentation tank has been working for a period of time, the sloping plate needs to be washed according to the usage. It is very inconvenient to wash the slant plate, and it is easy to produce a dead angle of washing, so it is inconvenient to maintain
