Embodiment Construction

[0034] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0035] Such as figure 1 , figure 2 and image 3 As shown, the present invention includes a water-passing system and a sediment collection system; the water-passing system includes three water-passing pools 2 connected end-to-end according to the flow direction for water to flow through, and each water-passing pool 2 has a water inlet 3 for water to flow in, The outlet 4 for the water in the water tank 2 to flow out and the sand leakage hole 5 communicated with the sediment collection system; The sand guide pipe 6 used for transporting the sediment settled in each water tank 2 to the sand collection tank 1 .

[0036] The number of water tanks 2 can also be two, four, five or more, and the specific number needs to be determined according to sp...

Abstract

The invention provides an urban road rainstorm runoff sediment filtering device, which includes a water passing system and a sediment collection system; the water passing system includes a number of water passing pools connected end to end according to the direction of water flow for water to flow through, and each water passing pool has a water supply The water inlet for inflow, the water outlet for the water in the water tank to flow out, and the sand leakage hole connected with the sediment collection system; The sand guide pipe used to transport the sediment settled in each water tank to the sand collection tank. Due to the adoption of the above technical scheme, the present invention has the advantages of reasonable structure and good sedimentation effect, which greatly reduces the sediment that finally flows into the bioretention system and reduces the risk of the bioretention system being blocked; it is not necessary to wait for the entire filter device to salvage the sediment. It can only be carried out when the work is stopped, and the sediment can be salvaged at any time; it is very convenient to clean the sediment, saving time and effort.

Description

technical field [0001] The invention belongs to the technical field of filtering devices, in particular to a sediment filtering device for urban road rainstorm runoff. Background technique [0002] Rainwater utilization is a technical means to use rainwater as urban miscellaneous water such as spraying roads, irrigating green spaces, and domestic water, considering the requirements of rainwater runoff pollution control, urban flood control, and ecological environment improvement. In the process of runoff after rainwater falls to the ground, it is often mixed with a large amount of nutrient elements and organic matter such as sediment, floating matter, nitrogen and phosphorus, especially in the Yunnan-Guizhou-Sichuan area, when mountain floods need to be used, the water is mixed with a large amount of mud The rainwater needs to be purified before it can be used; in order to prevent the sediment and floating in the rainwater from entering and blocking the bioretention system, ...
