Inclined tube or inclined plate sedimentation pool having sludge concentration function, and sludge discharging method thereof

Abstract

The invention discloses an inclined tube or inclined plate sedimentation pool having a sludge concentration function. The inclined tube or inclined plate sedimentation pool is characterized in that an inclined tube or inclined plate is arranged at an upper portion of a pool body, a water collection tank is arranged over the inclined tube or the inclined plate, a sludge discharging total channel is arranged at one side of the sedimentation pool, transverse bottom concentration sludge scrapers are arranged at the bottom of the pool body and is used for pushing sludge at the bottom of the pool to the sludge discharging total channel, a sludge collecting pit is arranged at one end of the sludge discharging total channel, and a vertical bottom concentration sludge scraper is arranged at the bottom of the sludge discharging total channel and is used for pushing the sludge at the channel to the sludge collecting pit. The inclined tube or inclined plate sedimentation pool has the advantages of saved engineering investment, small occupied area, flexible arrangement and management convenience, and realizes the optimal combination of a water treatment plant treatment technology.

Description

technical field [0001] The invention relates to a water treatment facility that can be widely used in the sedimentation unit of a water purification plant in a water supply project, in particular to an inclined pipe or inclined plate sedimentation tank with a sludge concentration function and a mud discharge method thereof. Background technique [0002] With the rapid development of urban construction, the available construction land in large and medium-sized cities has been decreasing, and the cost of land acquisition has been increasing. Therefore, the construction site area of ​​new water plant projects is often limited. In order to further save land resources, high-efficiency water treatment processes have been gradually popularized and widely used. Among them, there are many application examples of inclined tube (inclined plate) sedimentation tank. This tank is a sedimentation tank equipped with many parallel inclined plates with small intervals or parallel inclined tub...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide an inclined tube or inclined plate settling tank with sludge concentration function, which is suitable for new (expanded) waterworks projects with limited construction land, and solves the limitation of the water inlet width of traditional inclined tube settling tanks , There are problems of invalid water passing area, incomplete sludge discharge and relatively low concentration of sludge water
