Problems solved by technology

[0004] At present, the collection and treatment of initial rainwater in my country is still in its infancy. Collecting initial rainwater is only to prevent it from being discharged into the water body to pollute the water quality. However, little consideration is given to the purification and reuse of initial rainwater, and most of it is directly discharged into municipal domestic sewage pipes. 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

[0043] The structure of the integrated rainwater treatment device in this embodiment is as follows figure 1 As shown, the device includes a well body 1 and a cover plate 2 located above the well body. The interior of the well body is divided into a settlement zone A and a filtration-permeation zone B by an overflow wall 3, the overflow wall 3 is set from the bottom of the well body from bottom to top, and terminates at the cover plate 2 near the top of the well body , so that there is a communication port between the settlement zone A and the filtration-permeation zone B. A baffle plate 6 extending downward is also provided on the cover plate 2 close to the communication port in the settling area A. The bottom end of the baffle plate 6 is lower than the top of the overflow wall 3 . The cover plate 2 above the settlement area A is provided with a water inlet, and a grid plate 4 is arranged on the water inlet, and the initial rainwater carrying pollutants such as particulate m...

Embodiment 2

[0053] A method of utilizing the integrated rainwater treatment device in embodiment 1 to process rainwater is:

[0054] 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 4, and the filter bucket 5 can intercept relatively large garbage, leaves, etc. in the initial rainwater pollutants.

[0055] Under the action of gravity, some large particles will settle in the settlement zone A of the well body. With the rise of the water level in the subsidence zone A, a small amount of rainwater enters the biological medium layer 9 through the perforated drainage pipe 13, and after being treated by the biological medium layer 9, enters the gravel layer 8, and then penetrates directly into the ground through the permeable geotextile 7.

[0056] As the rainfall increases, when the water level rises to the top of the overflow wall 3, the rain...

Embodiment 3

[0060] The structure of a road rainwater treatment system in this embodiment is as follows: figure 2 As shown, the system includes a rainwater main pipe C arranged in parallel between the municipal roads R, and a plurality of rainwater branch pipes D extending to the municipal road R are arranged on both sides of the rainwater main pipe C, and the end of the rainwater branch pipe C is a rainwater outlet 17 , the integrated rainwater treatment device 18 in Embodiment 1 is provided at the rainwater outlet 17 .

[0061] Further, the integrated rainwater treatment device 18 is designed in different sizes and specifications according to the rainfall conditions of each rainwater outlet 17 .

Abstract

The invention relates to an integrated rainwater treatment device. The device comprises a well body and a cover plate positioned above the well body; an overflow wall is arranged at the bottom of thewell body from bottom to top, and the interior of the well body is divided into a settlement area and a filter-permeation area by the overflow wall; a water inlet is formed in a cover plate arranged above the settlement area; a filter and permeation medium is laid at the bottom of the filter-permeation area; an overflow pipe is arranged at the upper part of the side wall of the well body at the filter-permeation area; a perforated drain pipe passing through the overflow wall is arranged between the settlement area and the filter-permeation area; the perforated drain pipe passes through the overflow wall and extends into the filter and permeation medium. The integrated rainwater treatment device provided by the invention is good in rainwater treatment effect, and can effectively reduce thepollution, caused by pollutants, to natural water. In a treatment process, the integrated rainwater treatment device can run without needing to be driven by external powder and does not influence normal flood discharge. The treated water can permeate in situ so as to supplement underground water.

Description

technical field [0001] The invention relates to a rainwater purification device, in particular to an integrated rainwater treatment 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 include particulate matter, organic matter, heavy metals and other toxic and harmful substances. 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 flood damage, it has become an important emerging topic to col...
