Abstract

The invention provides a sedimentation tank which comprises four vertical face steel plates and a bottom face steel plate. The four vertical face steel plates are welded to form a hollow rectangular cylinder, the open end of the rectangular cylinder and the bottom face steel plate are welded to form a water container, and the vertical face steel plates and the bottom face steel plate are steel plates with the thickness of 20 mm. The problem that the sedimentation tank in the construction site is inconvenient to disassemble is solved, and the site construction efficiency is improved. The sedimentation tank is simple and reliable in structure and convenient to transport; the combined shaped sedimentation tank is economical and reliable, and can be repeatedly used.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to the field of sewage sedimentation tanks on construction sites. Background technique [0002] The country's environmental protection requirements for construction projects are gradually increasing. In order to treat construction sewage, sedimentation tanks have become a common sewage treatment method for various engineering projects. The three-stage advection sedimentation tank commonly used in projects at present is usually constructed of concrete, but masonry masonry structures or earth ponds lined with masonry can also be used. The advection three-stage sedimentation tank has a simple structure and is widely used, but it occupies a large area. The treatment effect on sewage with high turbidity is average. With the progress of the project, it is inconvenient to dismantle, and the demolition also causes waste of materials. It does not meet the development requirements of green ...
