Assembled upwelling medium filtering device

Abstract

The invention discloses an assembled upwelling medium filtering device, comprising a box body, wherein a baffle is arranged in an inner cavity of the box body; the baffle divides the inner cavity of the box body into a first-stage treatment chamber and a second-stage treatment chamber; a water inlet pipe is connected to the water inlet side of the box body, and a water outlet pipe is connected tothe water outlet side of the box body; a residue separation assembly and an upwelling medium filter are arranged in the second-stage treatment chamber; the residue separation assembly comprises an outer residue separation frame, an oil absorption rod and a residue separation breast board; the residue separation breast board is vertically suspended and fixed in the box body; the outer residue separation frame is arranged on one side, close to the baffle, of the residue separation breast board; the oil absorption rod is enclosed in the outer residue separation frame; the upwelling medium filteris arranged between the residue separation breast board and the water outlet side of the box body; and the upwelling medium filter is composed of a medium filtering frame and a medium filler. The device can achieve the effects of runoff control, retention and storage of surface water, reduction of flood peak flow, reduction of non-point source pollution, improvement of effluent quality standard, rainwater recycling and the like, and is low in maintenance cost.

Description

technical field [0001] The invention relates to the technical field of rainwater or sewage treatment, in particular to an assembled upflow medium filter device for rainwater or sewage treatment. Background technique [0002] my country is in a period of rapid urbanization, and remarkable achievements have been made in urban construction. At the same time, there are also problems such as high development intensity and many hard pavements. In particular, the construction of building roofs, roads, ground and other facilities has caused excessive hardening of the underlying surface, which has changed the original natural ecological background and hydrological characteristics of the city. More than 70% of the rainfall has been discharged as runoff. "Drought" has brought about problems such as deterioration of water ecology, shortage of water resources, water environment pollution, and lack of water security guarantees, seriously affecting the production and life of the people and...
