Sewage treatment plant inclined tube sedimentation tank with impurity filtering system

Abstract

The invention discloses a sewage treatment plant inclined tube sedimentation tank with an impurity filtering system, and relates to the technical field of sewage treatment. A sewage inlet pipe communicated with the interior of the sedimentation tank is arranged on the outer side of the sedimentation tank, a chemical adding mechanism for adding chemicals into the sedimentation tank is arranged on the outer side of the sedimentation tank, and a stirring mechanism for fully mixing sewage and the chemicals is arranged in the sedimentation tank; a filtered water outlet adjusting mechanism for adjusting the outflow of filtered water is arranged on the filtered water outlet of the side plate of the sedimentation tank, and a sewage outlet adjusting mechanism for adjusting the outflow of sewage is arranged on the sewage outlet of the side plate of the sedimentation tank. According to the sewage treatment device disclosed by the invention, sewage adsorbed by activated carbon is added into the sedimentation tank, an agent is added into the sedimentation tank, upper-layer liquid and lower-layer liquid in the sedimentation tank are respectively fully stirred and fully reacted, and then filtered water and settled sewage respectively flow out, so that the sewage treatment effect can be improved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an inclined tube sedimentation tank of a sewage treatment plant with an impurity filtering system. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, Agricultural sewage and medical sewage, etc., while domestic sewage is the sewage generated in daily life, which refers to the complex mixture of various forms of inorganic and organic substances. The sewage treatment plant is a special place for centralized treatment of sewage. During the operation of sewage treatment, it is necessary to add relevant additives to the sewage, and then use the mixing eq...

AI Technical Summary

Problems solved by technology

[0003] Sedimentation tank is a structure that uses sedimentation to remove suspended matter in water. The existing sedimentation tank does not treat impurities in sewage, and directly allows them to settle naturally. slow and inefficient

Moreover, most of the sewage treatment stirring devices in the sedimentation tank have low stirring efficiency and uneven stirring, which brings a lot of trouble, increases the cost, and is not conducive to the improvement of the convenience of use.
