Abstract

The invention relates to the technical field of sewage treatment, and discloses an impurity removal sewage treatment device which comprises a shell, a water diversion tank, an impurity removal box, a first siphon and a water purification box, a U-shaped groove is formed in the side wall of the lower portion of the water diversion tank, and an impurity discharging hole is formed in the middle of the lower side wall of the U-shaped groove. By designing the first siphon, the impurity removal box and the impurity discharging hole, sewage with floating impurities on the middle upper layer of the water diversion tank is sucked into the impurity removal box through the first siphon, the sewage permeates into the lower side of a floating block from the periphery of the floating block through the floating block, and the floating objects are retained on the upper side of the floating block; and when accumulation of floating objects on the upper side of the floating block is larger than elastic potential energy of a compression spring, the bottom of the floating block is in contact with a second baffle when the floating block moves downwards, and the second baffle opens the impurity discharging hole to discharging floating impurities out of equipment. The influence of floating impurities on the next sewage treatment step is avoided.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device for removing impurities. Background technique [0002] With the development of industry, coupled with the small amount of domestic water resources per capita and the uneven distribution of space, the demand gap for water resources is also increasing. As an emerging industry, the sewage treatment industry occupies an important position in the treatment of water resources. [0003] In the preliminary treatment of sewage, it is necessary to remove the visible impurities in the sewage to facilitate the next step of treatment. Due to the different content of visible impurities in the sewage, they are mainly divided into floating substances and sediments, while the floating substances and sediments in sewage It will affect the results of the next step of sewage treatment, resulting in low treatment efficiency of sewage treatment equipment, and even af...
