Problems solved by technology

[0006] Although the existing technology has a certain removal effect on suspended solids, there are problems such as large land occupation, high cost, relatively harsh hydraulic conditions, and large head loss. The effect of rainwater pollution control cannot meet the increasingly high water quality. Require

Embodiment Construction

[0036] Such as Figure 1~3As shown, the floating filter device at the end of the divided rainwater drainage system in this embodiment includes a filter chamber with a water inlet and a water outlet, the water inlet pipe 7 is connected to the water inlet, the water outlet pipe 8 is connected to the water outlet, and the water inlet pipe 7 is connected to the water outlet. The water pipe 8 is arranged horizontally, and the water inlet and the water outlet are arranged oppositely and are located on the same horizontal plane.

[0037] The filter cavity includes: a drainage channel 9 , a cleaning area 1 , a sedimentation area 2 , a suspended matter separation area 3 , an overflow area 4 , a floating filter layer 5 and an overflow weir 6 . The overflow weir 6 cuts off the filter cavity to form a drainage channel 9 . The bottom of the drainage channel 9 is the clearing area 1, which is connected to the sedimentation area 2, the sedimentation area 2 is located below the floating filt...

Abstract

The invention discloses a separated rainwater drainage system tail end floating type filter device which comprises a filter chamber with a water inlet and a water outlet. The filter chamber comprises a drainage channel, a suspended matter separation zone and a silt zone, wherein the drainage channel is used for downwards draining water bodies from the water inlet, the suspended matter separation zone comprises a filter channel of up-flow filtered water bodies and a floating filter layer which is filled into the filter channel, an inlet of the filter channel is communicated with the water outlet end of the drainage channel, an outlet of the filter channel is communicated with the water outlet, the floating filter layer comprises suspended particle filter materials and a fastener used for pressing and fixing the suspended particle filter materials, and the silt zone is located below the suspended matter separation zone and used for collecting impurities filtered by the suspended matter separation zone. According to the separated rainwater drainage system tail end floating type filter device, the structure is simple, the cost is lower, the power is not necessary, maintenance is convenient, suspended matter in the water and other pollutants adhered to the suspended matter can be effectively removed, and the floating filter layer is convenient and thorough to clean.

Description

technical field [0001] The invention relates to a rainwater drainage system, in particular to a floating filter device at the end of a divided rainwater drainage system. Background technique [0002] Suspended solids are one of the important pollutants in stormwater runoff. Urban stormwater runoff contains a large amount of suspended solids, which mainly come from the debris produced by the corrosion of vehicles, exhaust gas produced by motor vehicles, atmospheric dry and wet sediments, tires and Substances produced by brake friction and smoke and dust released by residents' chimneys, etc. In addition to its own pollution, suspended matter SS is also the carrier of many other pollutants (such as heavy metals, N, P, oily substances, toxic oil hydrocarbons (PHC) and polycyclic aromatic hydrocarbons (PAHS), etc.), especially Suspended particles with a large specific surface area. Before the rainwater runoff in the drainage pipe network is discharged into the receiving water b...
