Description

A flocculation sedimentation tank for a sewage treatment plant

Technical Field

The utility model relates to the field of sewage sedimentation, in particular to a flocculation sedimentation tank of a sewage plant.

Background Art

Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering the daily life of ordinary people. In some sewage treatment processes, it is necessary to inject some chemicals into the sewage to condense flocculent impurities or bacteria in the sewage into a ball, so as to precipitate the impurities in the sewage.

In a Chinese patent, a flocculation sedimentation tank for a sewage treatment plant is disclosed, and its patent number is CN219507728U. In the flocculation sedimentation tank for a sewage treatment plant in the patent, it includes a base frame, a water storage mechanism for storing sewage and discharging, and an auxiliary flocculation mechanism for treating condensed flocs in the water tank; through the above technical scheme, a coagulant is added to the water storage mechanism, and the second motor is started. The second motor drives the cross fan blades to rotate at the bottom of the water storage mechanism, so that the sewage in the water storage mechanism is affected to form a certain vortex, which can accelerate the condensation of debris in the sewage, and the condensed flocs can be almost in the middle of the water through the formation of the vortex. After turning off the motor, wait for the flocs to settle. When it is necessary to clean the flocs, start the first motor, and through the threaded connection of the lifting frame and the threaded shaft and the sliding cooperation with the limit shaft, the lifting frame can be lifted with the flocs for easy treatment, thereby avoiding the problem of accelerated component wear due to the need to disassemble and install the components in the device when the device is processed.

The above-mentioned published patents have the following disadvantages:

(1) The flocculant dripped into the sedimentation tank can make the sewage produce flocs after a period of sedimentation. However, in the prior art, the flocculant dripped into the sedimentation tank is not mixed evenly with the sewage, which affects the flocculation effect of the sewage and causes some pollutants in the sewage to fail to flocculate.

(2) In the prior art, the floccules after precipitation adhere to the surface of the screen and need to be cleaned manually, which makes the operators tired and also leads to unsatisfactory floccules cleaning effect.

(3) In the prior art, some smaller and finer flocs will pass through the mesh of the screen and go through the drain pipe along with the sewage. After the sedimentation tank has been used for a period of time, the drain pipe will be blocked by these flocs, causing blockage in the drain pipe and affecting subsequent drainage.
