Problems solved by technology

[0004] At present, the collection and treatment of initial rainwater in my country is still in its infancy. The collection of initial rainwater is only to prevent it from being discharged into the water body to pollute the water quality. The purification treatment of initial rainwater is rarely considered, and most of it is directly discharged into the municipal domestic sewage pipe network.
The concentration of pollutants contained in the initial rainwater is relatively high, especially the initial rainwater on the road. Direct discharge into the domestic sewage pipe network will bring a greater load to the sewage plant

Embodiment 1

[0042] The structure of the integrated rainwater filter device in this embodiment is shown in Figure 1, wherein the upper, lower, left, and right in Figure 1 are the cover plate direction, bottom direction, left side wall direction, and right side wall of the filter device direction. The device comprises a well body 1 and a cover plate 2 located above the well body. A water inlet is arranged on the cover plate 2 on the left side of the well body, a grille plate 5 is arranged on the water inlet, and a filter bucket 6 is arranged below the grille plate 5 . The water level on the left side of the bottom of the well body is higher than the water level on the right side. An overflow plate 7 is arranged longitudinally at the raised position of the water level. A dividing plate is set between the cover plate 2 and the right side well wall, the vertical plate 3 of the dividing plate is arranged downward from the cover plate 2 near the right side of the overflow plate 7, and the supp...

Embodiment 2

[0056] A method of utilizing the integrated rainwater filter device in embodiment 1 to process rainwater is:

[0057] When it rains, the initial rainwater carrying pollutants such as particulate matter, suspended matter, floating matter, nitrogen, phosphorus, oil and grease enters the well body through the grid plate 5, and the water filter bucket 6 can intercept larger garbage, leaves and other pollution in the rainwater Under the action of gravity, some large particles will settle in the settlement zone A of the well body. As the water level rises, when the water level rises to the bottom of the overflow pipe 8, the rainwater will enter the filter area B-1 from the overflow pipe 8. The lowermost end of the baffle 10 is lower than the bottom of the overflow pipe 8, and the floating matter will be intercepted by the baffle 10 in the settlement area A, and the rainwater will flow from below the baffle 10 to ensure that the floating matter will not enter the filter area B-1. Th...

Embodiment 3

[0061] The structure of a road rainwater treatment system in this embodiment is as follows: figure 2 As shown, its cross-sectional view is shown in image 3 As shown, the system includes a plurality of rainwater main pipes C arranged in parallel between municipal roads R, and a plurality of rainwater branch pipes D extending to municipal roads are arranged on both sides of the rainwater main pipe C, and the ends of the rainwater branch pipes D are For the rainwater outlet 17, the integrated rainwater filtering device 18 in Embodiment 1 is set at the rainwater outlet 17.

[0062] Further, the integrated rainwater filtering device 18 is designed in different sizes and specifications according to the rainfall of each rainwater outlet 17 .

Abstract

The invention provides an integrated rainwater filtering device. The device comprises a well body, a cover plate on the upper side of the well body, a partition plate, a supporting plate, an overflowplate and a filter, wherein a water inlet is formed in the cover plate, and a water outlet pipe is arranged on the well body; the partition plate is arranged downwards from the cover plate; the supporting plate is located between the side wall of the well body and the lower end of the partition plate; the inside of the well body is divided by the partition plate and the supporting plate in to a settling area, a filtering area and a water drainage area, the settling area is communicated with the water inlet, and the water drainage area is communicated with the water outlet pipe; an overflow channel used for making the settling area communicated with the water drainage area is formed between the overflow plate and the partition plate, a water inlet pipe used for making the settling area communicated with the filtering area is arranged between the overflow plate and the partition plate, and the water inlet height of the water inlet pipe is smaller than that of the overflow channel; the filter is arranged in the filtering area, and a water outlet of the filter is communicated with the water drainage area.

Description

technical field [0001] The invention relates to a water treatment device, in particular to an integrated rainwater filtering device. Background technique [0002] With the acceleration of urbanization, the impermeable area on the ground has increased significantly, and pollutants have gradually accumulated on these impermeable ground. When it rains, the rainwater washes the ground and the pollutants are washed into the rainwater runoff system to form rainwater runoff pollution. Rainwater runoff pollution is a kind of diffuse pollution. Pollutants enter natural water bodies and cause water pollution. The pollutants exist in the form of particulate matter, suspended matter, and floating matter, and contain toxic and harmful substances such as organic matter and heavy metals. Therefore, the process of urbanization and industrialization has led to increasingly serious water crisis and rain and flood hazards. [0003] With the aggravation of water source crisis and rain and floo...
