Problems solved by technology

[0002] Sedimentation tank is an indispensable main structure in the water purification process. Common advection sedimentation tanks, vertical flow sedimentation tanks, radial flow sedimentation tanks, inclined tube (plate) sedimentation tanks, etc. have difficulties in uniform water distribution and collection. There are many short-flow phenomena, many dead zones in the mud zone, difficulty in discharging bottom sediment, difficulty in maintenance of scraping and suction equipment, large floor area, high equipment cost, etc.

Abstract

The invention discloses a sedimentation tank device with a sedimentation wall. The sedimentation tank device with the sedimentation wall comprises a sedimentation tank. A water inlet distributing trough and a water outlet collection channel are arranged on the two inner side walls of the sedimentation tank in the length direction respectively, the inclined hole sedimentation wall which is installed at the bottom of the sedimentation tank and divides the sedimentation tank into two parts is vertically arranged in the middle of the sedimentation tank in the length direction, sedimentation channels penetrating through the two sides of the inclined hole sedimentation wall are evenly formed in the inclined hole sedimentation wall by inclining a certain angle, multiple water inlet distribution pipes extending downwards are arranged at the bottom of the water inlet distributing trough in the length direction, and perforated sludge discharge pipes of which one ends extend out of the sedimentation tank are installed on the portions, on the two sides of the inclined hole sedimentation wall, of the bottom of the sedimentation tank. According to the sedimentation tank device with the sedimentation wall, the problems of difficult uniform water distributing and water collecting, many pool short flow phenomena, many mud-field dead zones, difficult bottom silt discharge, difficult sludge scraping and sucking equipment maintenance and the like existing in common horizontal flow sedimentation tanks, vertical flow sedimentation tanks, radial flow sedimentation tanks and the like are solved, the occupied area is small, and the civil engineering and equipment cost is reduced.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sedimentation tank device with a sedimentation wall. Background technique [0002] Sedimentation tank is an indispensable main structure in the water purification process. Common advection sedimentation tanks, vertical flow sedimentation tanks, radial flow sedimentation tanks, inclined tube (plate) sedimentation tanks, etc. have difficulties in uniform water distribution and collection. There are many short-flow phenomena, many dead zones in the mud zone, difficult discharge of bottom sediment, difficult maintenance of scraping and suction equipment, large floor area, and high equipment cost. Contents of the invention [0003] In order to solve the above problems, the present invention provides a settling wall settling tank device to overcome the problems existing in the prior art. [0004] The present invention adopts following technical scheme to realize: [0005] A settli...
