Scum hopper device of aerated grit chamber of sewage treatment plant

Abstract

The invention provides a scum hopper device of an aerated grit chamber of a sewage treatment plant. The scum hopper device comprises a scum hopper body, a scum scraping plate guide rail, a supportingmechanism and a scum hopper discharging pipe, the scum hopper body is made of stainless steel and is fixed to a base plate, a hole is formed in the bottom of the scum hopper body, the scum hopper discharging pipe is connected to the scum hopper body, and the scum scraping plate guide rail and one side of the scum hopper body are connected and form a preset angle. The bottom of the scum scraping plate guide rail is connected with the scum hopper body through the supporting mechanism. The scum hopper device of the aerated grit chamber is made of SS304 stainless steel materials, the installationheight can be flexibly adjusted according to on-site civil engineering conditions, and the problem that the scum hopper device cannot effectively collect scum is solved. The scum hopper device of theaerated grit chamber is made of SS304 stainless steel materials, the installation height can be flexibly adjusted according to on-site civil engineering conditions, and the problem that the scum hopper device cannot effectively collect scum is solved.

Description

technical field [0001] The invention relates to the technical field of aeration grit chambers, in particular to a scum bucket device for aeration grit chambers in sewage treatment plants. Background technique [0002] At present, the scum tank of the aerated grit chamber of the sewage treatment plant usually adopts a reinforced concrete tank body and a pre-buried scum discharge pipe. In actual use, due to problems in design and construction coordination, or large changes in liquid level due to large changes in water volume, it often occurs that the height of the scum tank and the scum scraper does not match well, and the scum collection effect is poor. Contents of the invention [0003] According to the technical problems raised above, a scum hopper device for aeration and grit chambers in sewage treatment plants is provided. The technical means adopted in the present invention are as follows: [0004] A scum hopper device for aeration and grit chamber in a sewage treatm...
