Sewage precipitation treatment device

Abstract

The invention relates to the technical field of sewage treatment, and discloses a sewage precipitation treatment device. The device comprises a sewage precipitation tank, a water inlet pipe and a water outlet pipe; the water inlet pipe is fixedly mounted on the right side of the sewage precipitation tank, the water outlet pipe is fixedly mounted on the left side of the sewage precipitation tank, and an impeller is rotatably mounted in the water inlet pipe; a sewage precipitation mechanism is arranged at the upper end in the sewage precipitation tank, and comprises a rotating mechanism, a memory metal elastic plate, a special-shaped rubber block, a special-shaped flushing sleeve, an elastic metal plate, a pressing rod, a special-shaped air bag, a connecting pipeline, a fixed blocking rod, a transverse rod, a fixed extrusion rod, an extrusion spring, a stretching rod and a rotating wheel; the fixed blocking rod is fixedly mounted at the upper end of the interior of the sewage settling tank, and a trapezoidal groove is formed in the fixed blocking rod. According to the sewage treatment device, stains in sewage can be effectively settled while the flow speed of the sewage is increased, the sewage settling efficiency is improved, and more sewage can be treated.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage precipitation treatment device. Background technique [0002] Sewage treatment (wastewater treatment): 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, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] At present, sewage treatment needs to be treated by sedimentation, but most of the current sewage sedimentation tanks require the sewage to be prohibited from moving so that the particles can settle down. Therefore, the flow rate of sewage into the sedimentation tank needs to be very slow, which greatly affects the sewage treatment. efficiency, so a sewage sedimen...
