Abstract

The invention discloses a precipitation device for sewage treatment. The device comprises a plurality of precipitation tanks which are arranged in a stepped manner, the bottom of the upper precipitation tank is connected with the top of the lower precipitation tank, the adjacent precipitation tanks are communicated through a liquid discharge pipe, and a sludge scraper which is horizontally arranged is arranged in each precipitation tank. Precipitation is carried out for multiple times in the stepped arrangement manner, the adjacent lower precipitation tank can carry out receiving and precipitation on a liquid in the upper precipitation tank for multiple times to facilitate the precipitation work, and the gravitational potential energy of the liquid is converted into kinetic energy throughstepped arrangement to achieve the purpose of conveying the liquid between the precipitation tanks without power.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment and relates to a sedimentation device for sewage treatment. Background technique [0002] The sedimentation tank is a structure that uses sedimentation to remove suspended solids in water. It is an equipment for purifying water quality. It uses the natural precipitation of water or the effect of coagulation and sedimentation to remove suspended solids in water. The sedimentation tank is divided into horizontal sedimentation tanks and vertical sedimentation tanks according to the direction of water flow. Sedimentation tank. The sedimentation effect is determined by the flow rate of water in the sedimentation tank and the residence time of water in the tank. In order to improve the sedimentation effect and reduce the land area, honeycomb inclined tube counterflow sedimentation tanks, accelerated clarifiers, pulse clarifiers, etc. are often used. Sedimentation tanks Widely used in wastewate...
