Inclined-plate sedimentation basin used for sewage treatment

Abstract

The invention discloses an inclined-plate sedimentation basin used for sewage treatment. The inclined-plate sedimentation basin comprises a cover plate, a raw water pool and steel wire ropes, whereinthe bottom end of one side of the raw water pool is connected with a water inlet pipe; the other side of the raw water pool is fixedly provided with an inclined-plate sedimentation pool communicatingwith the raw water pool which comprises a curing pool, a charging pool and a coagulation pool; the charging pool is located between the curing pool and the coagulation pool; the water inlet pipe communicates with the coagulation pool; two symmetrical corners of the raw water pool and the inclined-plate sedimentation pool are separately fixedly provided with a motor supporting frame; four motor supporting frames are separately provided with a lifting motor; and one end of each of the four lifting motor is rotatably connected with a coiling drum through a rotating shaft. According to the invention, lifting mechanisms are arranged; each lifting mechanism comprises a lifting motor, a first pulley, a second pulley, one coiling drum and one steel wire rope; through working of the lifting motors,the coiling drums are driven to rotate for coil rolling and steel wire rope releasing; and thus, the cover plate is driven to rise and fall, and metal parts arranged on the cover plate are driven torise and fall.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an inclined plate sedimentation tank for sewage treatment. Background technique [0002] Inclined plate sedimentation tank refers to a sedimentation tank with inclined plates in the sedimentation area. Every two parallel inclined plates in the inclined plate sedimentation tank have a very shallow sedimentation tank, so that the treated water (or waste water) and The settled sludge moves and separates from each other in the shallow sedimentation layer. According to the force direction of their mutual movement, the inclined plate sedimentation tank can be divided into three different separation methods: cocurrent flow, counter flow and lateral flow. The inclined plate sedimentation tank is used The principle of "shallow sedimentation" shortens the sedimentation distance of particles, thereby shortening the sedimentation time, and increases the sedimentation are...

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of inclined plate settling tank for sewage treatment, to solve the problem that the metal part of the stirring device is rusted and corroded and the sludge deposited at the bottom of the settling tank is easy to adhere to the settling tank inner wall in the above-mentioned background technology. Easy to be discharged, easy to cause secondary pollution
