Example Embodiment

[0013] Example one

[0014] Sponge city construction road rainwater treatment system, including green belt 1, seepage storage well 2, storage well 3, seepage storage well 2, storage well 3 are covered with cover, green belt 1 is concave, green belt 1 Including an upper planting part and a lower purification part. The planting part consists of a net 4, a planting soil layer 5, a sandstone layer 6, and a biomass charcoal layer 7 arranged from top to bottom. The net 4 is made of bamboo fiber, Carbon fiber and superabsorbent fiber are made of blended fiber in a weight ratio of 1:3:1, and graphene photocatalytic net is laid under the screen; the purification part includes a purification box 8, and the outlet side of the purification box 8 is through a conveying pipe and a conveying pump. Grounding upper sprinkler 9, nearby residential water tank, underground long-distance transportation pipe 10; the overall installation height of infiltration well 2 is higher than that of water storag...

Example Embodiment

[0017] Example two

[0018] The sponge city construction road rainwater treatment system of this embodiment is the same as the first embodiment except for the following differences: the planting soil layer 5 is mixed with the following raw materials by weight: 8 parts of lemongrass powder, 20 parts of straw powder, 25 parts of yellow loam soil, 10 parts of fine sand, 5 parts of humus soil, 1 part of capsule microorganisms, 1 part of weeds, 3 parts of tea meal, 3 parts of adhesive; dosage of Bacillus, Saccharomyces cerevisiae and nitrifying bacteria in capsule microorganisms The ratio is 2: 5: 3. The adhesive is made by mixing Arabic gum, silicone, polyisobutylene, and silicate in a weight ratio of 3:1:3:2.

Abstract

The invention discloses a sponge city construction road rainwater processing system. The processing system comprises a green belt, a seepage storage well and a water storage well. The green belt comprises a planting part of the upper part and a purifying part of the lower part, wherein, the planting part comprises a separated net, a planting soil layer, a sand gravel layer and a biomass carbon layer which are sequentially arranged from top to bottom; the cleaning part comprises a purifying tank, and the outlet side of the purifying tank is connected with an sprinkler on the ground, a water tank for residents nearby, and a groundwater long distance pipe through a conveying pipe and a conveying pump. The periphery of the seepage water well, the storage well and the purifying tank is covered with the filtration mixture composed of pebbles, rice wheat stones, and limestone at any weight ratio. The other side of the water storage well is connected with a drain pipe, and the pipe opening of the drain pipe is directly connected with the filtration mixture. The sponge city construction road rainwater processing system has the advantages that rainwater is purified and efficiently used; the radial pressure of the rainwater is relieved; the rainwater can be directly absorbed and stored through the planting part, and can also directly enter the seepage storage well and the water storage well; the urban road waterlogging phenomenon is efficiently avoided.

Description

technical field [0001] The invention relates to the technical field of sponge city construction, in particular to a road rainwater treatment system for sponge city construction. Background technique [0002] Buildings in our country are basically made of hard pavement, without the ability to store and drain rainwater. Once a heavy rainstorm occurs, a large amount of rainwater will flow into the municipal pipe network for drainage. Not only the rainwater can only flow into the river in vain, but once the drainage is not smooth, there will Urban waterlogging phenomenon, and this kind of hard pavement increases the "heat island benefit" of the city. The construction of sponge city is to solve the above problems, implement the functions of absorbing, infiltrating, stagnating, storing, purifying, using and discharging rainwater for various urban facilities, and promote the local consumption and utilization of urban rainwater. But as far as the current road is concerned, even i...
