Sewage treatment device for quickly separating impurities

Abstract

The invention relates to the field of environmental protection, and specifically discloses a sewage treatment device for rapidly separating impurities, which includes a casing, a sedimentation tank, an upper cover, a drain pipe and a water feeding pipe, wherein an output shaft of the motor is vertically arranged downward, and the lower end of the output shaft is coaxially fixed to a transmission shaft passing through the upper cover downward; a vertical hollow shaft is fixed to the central axis of a rotating cylinder; a plurality of vertical filter screen boxes are arranged in the rotating cylinder and are evenly distributed along the circumference of the hollow shaft with equal included angles; a drainage hole communicating with the inside of the hollow shaft is opened on one end, of eachfilter screen box, located at the hollow shaft. According to the device, falling sewage is filtered by the rotating filter screen boxes, and the filter boxes are in contact with sewage in a three-dimensional structure manner, so that the contact area with the sewage is increased, and the flow of water is ensured. Attached impurities are liable to shed by changing rotation directions of the filterscreen boxes, and the impurities can be accumulated inside for a long time without affecting the filtration, thus reducing the frequency of maintenance and cleaning of the device, and reducing the use cost.

Description

technical field

[0001] The invention relates to the field of environmental protection, in particular to a sewage treatment device for rapidly separating impurities. Background technique

[0002] Sewage treatment refers to 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, medical treatment, and catering, and it has increasingly entered the daily lives of ordinary people. When treating sewage, it is first necessary to treat the impurities in the sewage. When treating impurities, it is necessary to use a sewage initial impurity removal device. After the initial impurity removal, the sewage will have a better treatment effect in the subsequent treatment. , it is the good effect of the initial impurity removal device that makes the impurity removal device an indispensable component of modern sewage treatment equipment.
