Floating Object Interception Device

Abstract

The invention discloses a flotage interception device. The device comprises a well, a water inlet pipe and a water outlet pipe, and the water inlet pipe and the water outlet pipe are arranged at the front end and the rear end of the well. The device is characterized in that a foundation wall and one or more filter screen bags are further included, the foundation wall extends upwards from the bottom of the well, openings of the filter screen bags are forward, and the filter screen bags are located on the foundation wall; the foundation wall is provided with a movable connection structure enabling the filter screen bags to move upwards; a water-permeable supporting structure is arranged under the filter screen bags; the upper surface of the foundation wall is lower than or flush with the lower surface of the water inlet pipe. The flotage interception device is simple in structure and convenient to use, flotage and particles of rainwater can be treated through the mode of combining gravity settling and flotage interception, and the flotage interception device is suitable for pretreatment of the rainwater before the rainwater enters a city main pipe or pretreatment before natural water is discharged through a rainwater pipeline.

Description

technical field [0001] The invention relates to the technical field of rainwater pretreatment, in particular to a floating object intercepting device. Background technique [0002] With the rapid development of urbanization, non-point source pollution caused by rainwater runoff has gradually become an important source of urban water pollutants. Pollutants in urban stormwater runoff mainly come from wet deposition caused by precipitation leaching atmospheric pollutants and leaching of urban impervious surface pollutants, and the latter accounts for more than 90% of the total amount of pollutants in stormwater runoff. Particulate matter is the main carrier of urban impermeable surface pollutants, such as: atmospheric deposition, vehicle exhaust, tire wear, snow melting agent, sediment on construction sites, solid waste and leachate and other particulate matter contain a large number of pollutants (COD, nutrients , organic matter, heavy metals, pathogens, etc.), will eventuall...

AI Technical Summary

Problems solved by technology

[0004] Therefore, when the rain falls to the ground and forms runoff, it will contain a large amount of particles such as sediment and floating objects. If the particles and floating objects in the rainwater are not intercepted and discharged directly to the natural water body, the natural water body will be polluted. Most of the rainwater is treated by filter screen, and the rainwater is pre-treated by simple filtration, but this filter filter method will bring many problems: 1. The filter screen may be blocked, hindering the discharge of rainwater and causing urban waterlogging

2. Floating objects are not collected after being intercepted, so cleaning is very inconvenient
