A sewage treatment device for urban sewers to prevent the accumulation of garbage and stink

Abstract

The invention discloses a sewage treatment device capable of preventing garbage from being piled and stinking and used for a city sewer and relates to the technical field of sewage treatment. The sewage treatment device capable of preventing the garbage from being piled and stinking and used for the city sewer comprises a frame body; a box body is welded at the internal bottom of the frame body; the left and right sides of the box body are also welded to the left and right sides of the internal wall of the frame body; a plurality of grilles are welded at the internal top of the frame body in rows; capturing mechanisms are fixedly connected to the bottom ends of the grilles; the bottoms of the capturing mechanisms are also fixedly connected to the top of the box body in rows in an equally spaced manner; and a collecting mechanism is arranged in the box body. According to the sewage treatment device capable of preventing the garbage from being piled and stinking and used for the city sewer, when sewage flows through the grilles, and garbage bags entrained in the sewage are in contact with the grilles, the garbage bags are captured and moved through the capturing mechanisms arranged on the grilles to prevent the garbage bags from being gradually accumulated on the surfaces of the grilles; and through the capturing mechanisms, the garbage bags are torn.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device used in urban sewage canals to prevent garbage accumulation and odor. Background technique [0002] Sewers are usually laid on both sides of the road to collect and transport rainwater. In addition to rainwater in daily life, they can also transport domestic sewage. As part of the urban drainage system, the scope of work it undertakes is to collect and transport sewage delivery and discharge. However, in actual use, surface garbage usually enters the sewage channel along with the water flow. The types and shapes of the garbage are complex. At the same time, the connection between the sewage channel and the ground will also be blocked by the grille to prevent large garbage from entering the sewage channel and prevent people and animals from falling into the sewage channel. Combined with the cooperation of the above two grilles, it makes The typ...

However, in actual use, surface garbage usually enters the sewage channel along with the water flow. The types and shapes of the garbage are complex. At the same time, the connection between the sewage channel and the ground will also be blocked by the grille to prevent large garbage from entering the sewage channel and prevent people and animals from falling into the sewage channel. Combined with the cooperation of the above two grilles, it makes The types of garbage that can enter the sewer through the grille are limited to flakes, garbage bags and some deformable small-volume garbage. Due to their large area, the garbage bags are blocked by the grille by 5% respectively. Tens of chances will be blocked by the grille or flow through the grille normally. When more garbage bags are blocked by the grille, their thickness and coverage on the surface of the grille will gradually increase, causing other garbage to accumulate on the surface of the garbage bag. With the accumulation of time, the grilles in the sewers are gradually blocked to the extent that it affects the normal drainage. Therefore, it is necessary to adopt a more effective treatment method for the garbage in the sewers in response to this situation.
