Embodiment 1

[0020] A rainwater purification system for a sponge city, which consists of: a rainwater purification device, and inclined edges are arranged around the top of the rainwater purification device, wherein the edge on one side is the curb 8, and a group of overflow holes are arranged on the edges of the other three sides 5. A dirt intercepting basket 1 is installed inside the edge, and the dirt intercepting basket includes a circular gauze frame, and an oil-absorbing bag 2 and a filter screen 4 are sequentially placed inside the circular gauze frame, and the rainwater There is an infiltration hole 6 at the bottom of the purification device, and an infiltration filtration system 9 is installed below the infiltration hole. The upper layer of the infiltration filtration system is coarse sandstone 10, the middle layer is fine sandstone 11, and the bottom layer is filter geotextile 12.

Embodiment 2

[0022] According to the sponge city rainwater purification system described in embodiment 1, one side of the rainwater purification device is pierced with an outlet pipe 3, and the circular gauze frame is connected and fixed by bolts to the dirt intercepting cover, and the upper edge of the The cover plate 7 is installed, and the water filtered by the filter geotextile enters the water storage tank or the municipal drainage system.

Embodiment 3

[0024] According to the sponge city rainwater purification system described in embodiment 2, the described oil-absorbing bag adopts high-efficiency oil-absorbing cotton, the filter screen filtering diameter is more than 1mm particle diameter, and the described coarse gravel diameter is 1-2cm, so The above-mentioned fine sand is 0.5-1cm.

Abstract

The invention discloses a sponge city rainwater purification system and rainwater purification method. At present, reinforced concrete and stainless steel reservoirs are used for collecting rainwaterin China, the two construction processes are complex, the number of procedures is large, and a lot of manpower, material resources and financial resources are wasted. The sponge city rainwater purification system comprises a rainwater purification device; inclined edges are arranged at the periphery of the upper part of the rainwater purification device, wherein the edge at one side is a road edge(8), and the edges at the other three sides are each provided with a group of overflow holes (5); sewage intercepting baskets (1) are arranged in the edges; each sewage intercepting basket comprisesa circular gauze frame; an oil absorption bag (2) and a filter screen (4) are sequentially arranged in each circular gauze frame; infiltration holes (6) are formed in the bottom of the rainwater purification device; an infiltration filtering system (9) is arranged below the infiltration holes; coarse gravels (10) are arranged on the upper layer of the infiltration filtering system; fine gravels (11) are arranged on the middle layer of the infiltration filtering system; and filtering geotechnical cloth (12) is arranged on the bottom layer of the infiltration filtering system. The rainwater purification method of the invention is used for the sponge city rainwater purification system.

Description

Technical field: [0001] The invention relates to the technical field of urban construction, in particular to a sponge city rainwater purification system and a rainwater purification method. Background technique: [0002] Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores, infiltrates, and purifies water. Utilization, the construction of sponge cities should follow the principles of ecological priority, combine natural methods with artificial measures, and ensure the safety of urban drainage and waterlogging, maximize the accumulation, infiltration and purification of rainwater in urban areas, and promote rainwater resources. utilization and ecological environment protection; [0003] At present, the methods of collecting rainwater in the domestic market include traditional reinforced concrete and stainless steel cisterns. These two method...
