Background

The existing vertical sedimentation tank is also called as a vertical sedimentation tank, and is a sedimentation tank in which wastewater in the tank flows vertically. The plane figure of the pool body is circular or square, water enters the pool from top to bottom through a water inlet pipe arranged at the center of the pool, an umbrella-shaped baffle is arranged below the pipe to ensure that wastewater slowly rises along the whole water passing section after being uniformly distributed in the pool, suspended matters settle into a conical sludge settling hopper at the bottom of the pool, and clarified water flows out from the periphery of the pool along a peripheral overflow weir. A baffle plate and a scum groove are arranged in front of the weir to intercept scum and ensure the quality of effluent. One side of the pool is provided with a mud discharging pipe close to the pool wall, and mud is discharged periodically by hydrostatic pressure. The vertical flow sedimentation tank has the forms of round, square and the like.

In the process of treating sewage by using the sedimentation tank, because the retention time of sewage raw water in the sedimentation tank is longer (2-6 h), the sludge amount in the sedimentation tank is larger, if the sedimentation sludge is not discharged out of the tank in time, the sewage turbidity overflowing from the upper part is increased, and the effluent quality of the sedimentation tank can be seriously influenced. Consequently, sedimentation tank needs often arrange mud, and current row's mud mode is connected the sludge discharge pipe through the sludge pump and takes mud out, nevertheless because the sludge pump sets up at the sludge discharge pipe distal end, arranges mud effect poor, often causes the sludge discharge pipe to block up.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.

A vertical flow type gas stripping mud discharging sedimentation tank as shown in figure 1 comprises a tank body 1, a water inlet channel 2, a central water inlet pipe 3 and a mud discharging pipe 4. The upper part of the tank body 1 is provided with a water outlet channel 5, and the lower part of the tank body 1 is provided with a sludge hopper 6. The water inlet channel 2 is positioned at the top of the tank body 1, the central water inlet pipe 3 vertically extends into the tank body 1 from the center of the upper part of the tank body 1, the upper end of the central pipe 3 is communicated with the water inlet channel 2, and the outlet end of the central water inlet pipe 3 is provided with an umbrella-shaped reflecting plate 12.
