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.

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 storage well 3, and the near bottom of infiltration well 2 is connected to water storage well 3 through pipelines, The upper part of one side of the water storage well 3 is connected with the sand and gravel layer 6 of the planting part through the rainwater outlet, and the middle part of one side of the water storage well 3 is connected with a purification tank 8. The purification tank 8 is vertically fixed with a multilayer filter screen 11, the purification tank 8 is also connected with an aeration pump, which is placed in the planting part; around the seepage storage well 2, storage well 3, and purification tank 8 are covered with pebbles, rice stone, limestone according to any weight ratio. To filter the mixture through water seepage, a drain pipe 12 is connected to the other side of the water storage well 3, and the nozzle of the drain pipe 12 directly reaches the point where the water seepage filter mixture is located.
[0015] Planting soil layer 5 is a mixture of the following raw materials: 10 parts of lemongrass powder, 15 parts of straw powder, 35 parts of yellow loam, 20 parts of fine sand, 15 parts of humus soil, 3 parts of capsule microorganisms, 3 parts Parts, 10 parts of tea meal, 5 parts of adhesive. The adhesive is made by mixing Arabic gum, silicone, polyisobutylene, and silicate in a weight ratio of 3:3:3:5. Capsule microorganisms are respectively cultured Bacillus, Saccharomyces cerevisiae, and nitrifying bacteria in their respective media to the logarithmic growth phase, centrifuged to collect the bacteria, washed with 0.85% normal saline respectively to prepare a bacterial suspension, and added 3% to the bacterial suspension Sodium alginate solution to obtain a sodium alginate bacterial suspension, then add the three kinds of bacteria to the sodium alginate bacterial suspension and mix evenly, drop 4% calcium chloride solution and solidify for 20 minutes to obtain gel beads, and then Place the gel beads in a 1.5% chitosan solution for 10 minutes, and pass ozone while covering the film. The weight ratio of the gel beads to the chitosan solution is 1:4. Remove them and place them in the glutaraldehyde solution. Connected for 5 minutes to prepare, wherein the dosage ratio of Bacillus, Saccharomyces cerevisiae and nitrifying bacteria is 3:2:2.
[0016] The filter screen 11 has three layers, and from the water inlet end to the water outlet end, there are an activated carbon filter screen, a diatomaceous earth filter layer, and a zeolite filter layer coated with zeolite in order.

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.
