Pretreatment sediment box for sewage treatment

Abstract

The invention discloses a pretreatment sediment box for sewage treatment. The pretreatment sediment box comprises a protective shell, a sand discharge main body is fixed to the center of the upper end face of the protective shell, the sand discharge main body comprises a first sand guiding pipe, a sand lifting pipe is connected to the center of the lower end face of the first sand guiding pipe in a penetrating mode, a three-phase asynchronous motor is fixed to the upper end face of the first sand guiding pipe, a water suction pump is fixed to the upper end face of the three-phase asynchronous motor, a sediment main body is fixed to the interior of the protective shell and comprises a third filter screen, a buffer plate is fixed to the upper end face of the third filter screen, a cable support shell is fixed to the end, deviating from the buffer plate, of the third filter screen, a second filter screen is fixed to the upper end face of the buffer plate, and a first filter screen is fixed to the upper end face of the second filter screen. Accordingly, by arranging the protective shell, the sand discharge main body and the sediment main body, the work efficiency of sewage treatment can be improved, and meanwhile the sewage can be sedimented rapidly.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a pretreatment sedimentation tank for sewage treatment. Background technique [0002] The sedimentation tank is used for the preliminary treatment of sewage, and the impurities and garbage inside the sewage are preliminarily precipitated, so as to facilitate the subsequent rapid treatment of sewage. However, the current sedimentation tank has the following defects: 1. The current sedimentation tank is When the sewage is initially filtered, relatively large sand and gravel cannot be quickly discharged, thereby reducing the efficiency of sewage treatment. Second, the current sedimentation tank cannot quickly filter sewage, and cannot clean relatively large ground particles. . Contents of the invention [0003] The object of the present invention is to provide a pretreatment settling tank for sewage treatment to solve the problems raised in the above-mentioned ...
