Problems solved by technology

However, the installation of the mud scraper will make the structure of the sedimentation tank complicated. Due to the need to work in water, there are higher requirements for the structural components of the mud scraper.
It will increase the construction cost of the sedimentation tank. At the same time, from the current practical experience, the sludge removal effect is not very ideal after the mud scraper is installed.

Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0012] see figure 1 , figure 2 , the waste water enters the central pipe 10 of the sedimentation tank from the water inlet pipe 8, and after passing through the central pipe 10, the water enters the sedimentation area upwards. During the upward flow, the water flows upwards, while the mud settles downwards, and finally the clarified water is discharged through the outlet weir 7 , and the mud settles down to the surface of the conical sludge hopper 11 . A diversion groove 12 formed by a deflector 2 is arranged on the surface of the conical sludge hopper. When the surface 11 of the conical sludge bucket accumulates a large amount of sludge due to precipitation, the pressure water passes through the water distribution vertical pipe 4 and the water distribution ring pipe 3, and finally enters the porous water distribution disturbance pipe 1, relying on the por...

Abstract

The invention discloses a novel vertical flow type sedimentation tank. A flow guide plate is distributed on the surface of a tapered sludge bucket of the sedimentation tank and then a flow guide groove is formed; a porous water distribution disturbance pipe is distributed in the flow guide groove. According to the novel vertical flow type sedimentation tank disclosed by the invention, the flowability of sludge deposited on the surface of the tapered sludge bucket is strengthened through a disturbance effect of the porous water distribution disturbance pipe, so that the sludge can slip to the bottom of the tapered sludge bucket better. The novel vertical flow type sedimentation tank disclosed by the invention has the advantages of simple structure and convenience for implementation; the sludge is not accumulated in the sedimentation tank and the sludge discharging effect is good.

Description

technical field [0001] The invention belongs to a waste water treatment sedimentation device, in particular to a novel vertical flow sedimentation tank. Background technique [0002] In the field of wastewater treatment technology, vertical flow sedimentation tanks are mainly used for solid-liquid separation. For example, sedimentation and separation of coagulation process effluent, sedimentation and separation of biochemical process effluent, etc. The sludge in the vertical flow sedimentation tank relies on the conical sludge bucket at the bottom of the sedimentation tank to collect the sludge settled in the sedimentation area, and finally, the sludge is discharged through the sludge discharge pipe at the bottom. The angle of the conical sludge bucket is generally 50°-55°. However, in the actual application process, because the specific gravity of sludge is very close to that of water, its fluidity in water is relatively poor. Even if the conical sludge hopper is at 50°-...
