COHESION PRECIPITATION SYSTEM FOR SETTLING PRECIPITATION TANK OF WATERWORKS

摘要

The present invention is the upper end is open, the raw water is introduced through the porous plate by the inlet means to one side, the raw water is flowed out by the outlet means to the other side, the sedimentary recess that is deposited by the cohesive sediment of foreign matter inside the raw water introduced at the bottom And settling tank is formed; It is a rectangular parallelepiped having a frame made of a mesh network, and a plurality of withdrawal insertion holes inclined from the upper end to the inlet side is formed, and a plurality of guide rollers are fixed at the lower part of the withdrawal insertion hole, and a sedimentation cradle with moving rollers is formed at both upper ends. And settling guide device is fixed to be locked to the upper end of the settling tank; Gravitational sedimentation hole penetrates up and down on the inside, and a sedimentation inlet hole is formed on the front side, and protrudes downward on the inner side of the front side so that the tip is bent in the same manner as the inclination of the body to narrow the inner diameter of the gravity sedimentation hole. A plurality of contact sedimentation pins are formed, the withdrawal ring protrudes on the upper side, and relates to a coagulation sedimentation apparatus for sedimentation tanks used in water treatment facilities having a sedimentation guide plate inserted into the withdrawal insertion hole of the sedimentation guide device.;Sedimentation guide device, drawout insertion hole, sedimentation guide plate, gravity sedimentation hole, contact sedimentation pin, sedimentation tank
