specific Embodiment approach

[0056] Specific implementation method: in the early stage of rainfall, choose to close the pressure valve 36 at the bottom of the rainwater tank 3, open the water stop valve 33 at the top of the rainwater tank 3, the rainwater from the roof 1 of the residential area will enter the rainwater tank 3 after passing through the rainwater pipe 2, and pass through it vertically from top to bottom Sand and gravel filter layer 371, geotextile 373, pebble filter layer 372 and steel wire mesh 374, then pass through the drainage hole 311 at the bottom of the partition plate 31, enter the other side of the partition plate 31, and then pass through the steel wire mesh vertically from bottom to top 374, pebble filter layer 372, geotextile 373 and gravel filter layer 371 are discharged through the upper drain pipe 34; in the later stage of rainfall, the water stop valve 33 is selected to be closed, and when the rainwater accumulated in the rainwater tank 3 reaches a certain amount, the pressure...

Abstract

The invention relates to a sponge combination system applicable to old communities and a rainwater treatment method of the sponge combination system. The sponge combination system comprises a rainwater tank, a stone cage and a rainwater garden, a water inlet of the rainwater tank is communicated with community roof rainwater through a rainwater pipe, a drainage opening of the rainwater tank is communicated with the stone cage through a drainage pipeline, and the stone cage is communicated with the rainwater garden; the rainwater garden is internally provided with an overflow well, and is communicated with an underground municipal pipe network through the overflow well. The sponge combination system applicable to the old communities and the rainwater treatment method of the sponge combination system have the advantages that different rainfall sponge treatment measures are combined into the system, the filtering and collecting capacity of rainwater can be drastically strengthened, the sponge combination system is modularized, construction is facilitated, the reconstruction cycle is short, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of sponge city construction, in particular to a sponge combination system suitable for old communities and a rainwater treatment method thereof. Background technique [0002] Rainwater is an important link in the urban water cycle and regional water cycle system, and plays an extremely critical role in regulating and supplementing regional water resources and improving the ecological environment. China is currently in the stage of rapid urbanization. With the improvement of urbanization level and rapid economic development, the problem of urban rainwater is becoming more and more prominent. The main manifestations are: serious pollution of rainwater runoff; increased risk of urban flood disasters; massive loss of rainwater resources; serious damage to the urban ecological environment, etc. Many of the planning and design of urban drainage systems in our country still only stay on how to directly discharge u...
