Further, the bottom wall of the sedimentation tank 20 has an inclined slope, water outlet holes are formed in the bottom of the side wall of the sedimentation tank 20 on one side of the slope bottom, and the filter screen 11 is installed in the water outlet holes, so that relatively clean rainwater can seep out to a soil layer on one side.
In order to facilitate the precipitation of the sewage-containing rainwater fed into the sedimentation tank, a sedimentation baffle 10 which is vertically arranged is also arranged on the bottom wall of the sedimentation tank 20; a sewage drain pipe 22 is further connected to the bottom wall of the sedimentation tank 20, the sewage drain pipe 22 is provided with a sewage inlet and a sewage outlet, the sewage inlet is connected to one side of the sedimentation baffle 10 on the slope, and the water outlet hole of the sedimentation tank 20 is positioned on one side of the sedimentation baffle 10 below the slope. Due to the arrangement of the sedimentation baffle 10, sediment such as silt is mainly deposited on one side of the slope of the sedimentation baffle 10, and the sewage outlet is arranged at the sediment outlet, so that the silt can be rapidly pumped out through the sewage pipeline 22 under the action of the sewage pump 23, and the sediment is removed more thoroughly.
In the embodiment, the vegetation purifying layer comprises a soil layer, a pebble layer 3 and a sand layer 4 paved from top to bottom, and the green plants 1 are planted on the soil layer. The soil layer, the pebble layer 3, the sand layer 4 and the inner wall of the rainwater garden self-regulation flower pond are also provided with water storage sponge, the longitudinal height of the water storage sponge is greater than the sum of the thicknesses of the pebble layer 3 and the sand layer 4, the bottom surface of the water storage sponge is leveled with the bottom surface of the sand layer 4, and the top surface of the water storage sponge is positioned above the top surface of the pebble layer 3. Illustratively, the water storage sponge may be cylindrical, and the soil layer, the pebble layer 3 and the sand layer 4 are laid in the inner space of the cylindrical water storage sponge; or two pieces of water storage sponge are arranged, wherein the first water storage sponge 2 and the second water storage sponge 13 are respectively arranged on two sides of the soil layer, the pebble layer 3 and the sand layer 4. The water storage sponge can play a role in water retention.
In this embodiment, the first irrigation device has a first water outlet pipe 5 and a first water pump 8, an inlet of the first water outlet pipe 5 is located in the overflow pool 7, and an outlet of the first water outlet pipe 5 extends to the vegetation purifying layer; the first water pump 8 is configured to pump rainwater in the overflow pool 7 into the vegetation purifying layer.

In this embodiment, the water level monitor one 9 and the water level monitor two 16 are arranged in the water reservoir 17, and the water level information of the water reservoir 17 is monitored in real time by arranging the water level monitor, and the controller controls the starting time of the water purifying work and the actions of the water pump and the valve based on the received water level information.
In this embodiment, the water guiding layer not only has water guiding and filtering functions, but also has the function of supporting the vegetation purifying layer above. The water guide layer is provided with a top plate and a bottom plate, and water holes are formed in the top plate and the bottom plate; a drainage baffle 14 and a water seepage tank 15 are arranged between the top plate and the bottom plate, the water seepage tank 15 is vertically arranged, and the drainage baffle 14 is obliquely arranged.
The rainwater garden self-regulation flower pool provided by the embodiment has six functions of seepage, stagnation, storage, purification, use and discharge. Wherein "ooze" is to carry out the preliminary filtration to the rainwater through top pebble layer 3 and sand bed 4, and the secondary filtration is carried out through infiltration tank 15 after that, and the filter screen 11 of sedimentation tank 20 diapire apopore is final filtration at last. The 'stagnation' firstly realizes detention through the function of top 'seepage', secondly slows down the rainwater storage speed through the drainage baffle 14 arranged obliquely below the top filter layer, then the water storage sponge one 2 and the water storage sponge 13 on two sides of the top filter layer also play the function of detention, and finally realizes detention through the water storage pool 17 and the overflow pool 7. The storage is mainly represented by a reservoir 17 and an overflow tank 7: firstly, a reservoir 17 in the middle of the flower pond is used as a main accumulation function of the rainwater flower pond; one side of the reservoir 17 is provided with an overflow port and an overflow pool 7, and when the reservoir 17 stores more water in rainy season, the overflow port can store the surplus rainwater in the overflow pool 7. The "clean" is primarily purified firstly by the "seeping" function and secondly primarily purified by the water purifier 18 in the reservoir 17 for the accumulated rainwater. Meanwhile, the water level monitor I9, the water level monitor II 16 and the overflow port 6 are matched to control the starting time of water purification work. The sewage discharged from the reservoir 17 may be purified and discharged through the precipitation baffle 10 after precipitation filtration. The water pump II 19 is used for carrying out self-circulation irrigation on the flower pond upwards through the water outlet pipe II 12 by the water after thoroughly purifying in the reservoir 17. The rainwater in the overflow pool 7 in the rainy period can also be guided into the green plant 1 for recycling through the water outlet pipe 5 by the water pump 8. The 'discharge' is to sediment the sewage left after purification in the sewage area of the sedimentation tank 20 by the action of the inclined gravity at the bottom and then filter and discharge the sewage through the filter screen 11. The deposited sludge is regularly pumped out through the sewage drain pipe 22 and the sewage pump 23, so that the normal purification function of the regulating and accumulating flower pond is ensured.
Compared with the prior art, the self-regulation flower pool for the rainwater garden strengthens the urban rainwater flood management capability, and can reduce the flood phenomenon through the detention and water storage functions in rainy seasons; the self-circulation function is achieved by utilizing the water accumulated by the self-water-storing flower pond through the water storing function and the water purifying function in dry seasons.
The foregoing description of the embodiments has been provided for the purpose of illustrating the general principles of the application, and is not meant to limit the scope of the application, but to limit the application to the particular embodiments, and any modifications, equivalents, improvements, etc. that fall within the spirit and principles of the application are intended to be included within the scope of the application.
