Embodiment 1

[0036] See attached Figure 2-14 As shown, the initial rain collection pond with the automatic abandonment of late rainwater includes: the initial rain collection pond 20, the initial rain collection pond 20 includes a collection pond main body 21, and its feature is that: one side of the collection pond main body 21 is connected with a drainage assembly 10, The drainage assembly 10 includes a drainage base 11 connected to the collection tank main body 21, the top surface of the drainage base 11 is flush with the top surface of the collection tank main body 21, and the drainage base 11 has a drainage channel that is horizontally arranged and communicated with the collection tank main body 21 12. There is a distance between the bottom surface of the drainage channel 12 and the top surface of the main body 21 of the collection tank. A trash rack 14 is provided at the connection between the main body of the collection tank 21 and the drainage channel 12, and a drainage channel com...

Embodiment 2

[0045] The initial rain collection tank with the automatic abandonment of later rainwater of the present invention has a method for collecting initial rain: the initial rain collection tank 20 is empty before the rainfall, and the initial rainwater directly enters the main body 21 of the collection tank. When the water level of the rain collection tank gradually reaches the design water level height h, the later rainwater overflows from the drainage assembly 10, and the overflowed clean rainwater is discharged into receiving water bodies such as rivers and lakes through the first drainage pipe 60 connected thereto.

Embodiment 3

[0047] The initial rain collection tank with the automatic abandonment of later rainwater of the present invention has a method for collecting initial rain: the initial rain collection tank 20 is empty before the rainfall, and the initial rainwater directly enters the main body 21 of the collection tank. When the water level of the rain collection tank gradually reaches the design water level height h, the first floating body 41 blocks the first flow hole 31 to prevent subsequent rain from entering the main body 21 of the collection tank below the partition plate 30. At this time, the later rainwater overflows from the drainage assembly 10. The overflowing clean rainwater is discharged into the purification assembly 80 through the second drainage pipe 70 connected thereto, and after the purification of the water body by the purification assembly 80, it is discharged into the rear rain collection pool 90. The excessive urban rainfall exceeds the rear rain collection pool 90. Dur...

Abstract

The invention discloses an initial rainwater collecting pool with a later rainwater automatic discarding function, and belongs to the field of rainwater treatment. The initial rainwater collecting pool comprises an initial rainwater collecting pool body, wherein the initial rainwater collecting pool body comprises a collecting pool main body, and a drainage assembly is connected to one side of thecollecting pool main body and comprises a drainage base element connected with the collecting pool main body; the top surface of the drainage base element is flush with the top surface of the collecting pool main body, the drainage base element is provided with a drainage channel which is horizontally arranged and communicates with the collecting pool main body, and a gap is formed between the bottom surface of the drainage channel and the top surface of the collecting pool main body; and a trash rack is arranged at the communication position of the collecting pool main body and the drainagechannel, and a drainage through groove communicating with the drainage channel is formed in the side surface of the drainage base element. According to the invention, the dilution effect of the laterrainwater on initial rainwater is reduced, the sedimentation rate of pollutants in the rainwater is improved, the initial rainwater and the later rainwater are efficiently collected and purified, theproblem of runoff pollution of the rainwater to cities is solved, and the initial rainwater collecting pool can be applied to the construction of sponge cities on a large scale and has the characteristic of good compatibility.

Description

technical field [0001] The invention belongs to the field of rainwater treatment, and in particular relates to a first rain collection pool with automatic abandonment of late rainwater. Background technique [0002] According to relevant research, the initial flushing effect of rainwater outflow from a small catchment surface is obvious, that is, the initial rainwater pollutant content is high, and the later rainwater is relatively clean. figure 1 As shown in the figure, it can be seen that the rainwater runoff pollution in the early stage of rainfall is serious, because the initial rainwater is mixed with a large amount of dust and sediment, and the content of organic pollutants is high, the quality of rainwater is very poor, and the pollution of rainwater runoff in the early stage of rainfall is serious It can be proved in domestic and foreign research. Therefore, the treatment and disposal of initial rainwater is the key technology of rainwater recycling. At present, the ...
