Description

Ecological tree pool with floater for automatically controlling initial rainwater drainage and working method
Technical Field
The invention relates to the technical field of rainwater control and rainwater utilization, in particular to an ecological tree pool with a floater for automatically controlling initial rainwater drainage and a working method.
Background
Urban rainwater runoff carries a large amount of pollutants of different types, which is one of key factors threatening the quality of urban water environment. A large number of researches show that the initial scouring phenomenon of pollutants is usually obvious for runoff at the source catchment surfaces of roads, roofs and the like. That is, the initial concentration of runoff pollutants at such catchment surfaces is significantly higher than the later stage of runoff, and the pollution load occupying a larger proportion of the rainfall in a smaller volume at the initial stage of runoff is carried. Therefore, if the initial rainwater runoff pollution can be effectively controlled, the runoff pollution can be controlled economically and efficiently, and an important support is provided for guaranteeing the urban water environment quality. Two modes of volume control and flow control are generally adopted in research and practice on how to realize effective control on initial rainwater. The volume control is to control a certain runoff volume (generally, the fixed rainfall corresponding to the catchment surface of the runoff flow) at the initial runoff generation stage; and the flow control adopts a certain fixed flow of runoff (including runoff with higher pollution concentration at the initial stage of the runoff and runoff with lower pollution level at the middle and later stages) of the whole process of the rainwater runoff by adopting a flow abandoning pipe and a canal.
The two methods have advantages and corresponding limitations, for volume control, a special structure is usually required to be arranged to store initial runoff with a certain volume, although only initial rainwater with high initial pollution level of the runoff can be guaranteed to be abandoned, and the flow abandoning efficiency is high, in order to guarantee effective control of initial rainwater pollution, even if the scale of the flow abandoning pool is determined according to the initial rainfall of 2-3 mm, the volume of the flow abandoning facility is still large, and large space requirements are required, especially for a water converging surface with large area, such as a large public building roof, a plurality of roads and the like. The large space requirements limit the application of the initial waste stream facility based on volume control to a certain extent; for flow control, the waste flow is realized by presetting a waste flow pipe (canal), which is commonly called as 'small pipe waste flow'. The flow discarding device has small space requirement, and does not need a storage facility for discarding the initial rainwater, but the biggest problem of the mode is to discard the flow of the whole process of the rainwater runoff, the runoff with lower pollution level in the middle and later periods of the runoff is also discarded to be discharged, and the flow discarding efficiency cannot be effectively guaranteed. More serious is, no matter what kind of mode is abandoned to the current initial stage rainwater, abandons the rainwater runoff after flowing and discharges to sewage pipes, and then finally gets into sewage treatment plant, if abandons the runoff that the later stage pollution degree is lower in the runoff to sewage pipes, finally gets into sewage treatment plant, the low concentration is intake and will seriously influence sewage treatment plant's operating efficiency (because of pollutant concentration is low, the carbon source is not enough, influences sewage treatment plant biological treatment process's operation). In sum, how to realize the efficient flow discarding of the initial rainwater runoff is a key problem to be solved urgently in the field.
The ecological tree pool is a typical urban rainwater control and utilization technical measure and is also a common technical measure in the construction of sponge cities at present. For the ecological tree pool, how to effectively control the initial runoff pollution of the road and realize the high-efficiency flow abandoning of the initial rainwater runoff is also a key problem to be solved in the field. The ecological tree pool based on the initial rainwater and snow-melting runoff discarding technology which is disclosed at present can realize a certain pollution control effect on the initial rainwater and snow-melting runoff, but has one or more of the following problems: 1) the flow discarding mode of initial runoff and snow melting runoff mostly adopts a manual mode, a large amount of manpower is consumed, and the operation and maintenance cost is increased; 2) the limitation of singly adopting volume control or flow control to realize initial rainwater drainage is not effectively solved, and drainage efficiency and initial runoff pollution control efficiency are not high.

As shown in fig. 1 to 9, an embodiment of the present invention discloses an ecological tree pool with a float for automatically controlling initial rainwater drainage, including: the waste water treatment device comprises a floater 3, a waste water drainage ditch 2 and a water distribution area 31, wherein one end of the waste water drainage ditch 2 is provided with an inflow port 1, the other end of the waste water drainage ditch is communicated with a sewage pipeline 6, the bottom surface of the waste water drainage ditch 2 is provided with a first through hole, the first through hole is matched with the floater 3, a stagnation and storage space 13 communicated with the waste water drainage ditch 2 is arranged below the waste water drainage ditch 2, a stagnation and storage space 13 communicated with the water distribution area 31 is arranged below the water distribution area, the floater 3 is arranged in the stagnation and storage space 13 below the waste water drainage ditch 2, the floater 3 can move up and down in the first through hole, and the upper surface of the floater 3 is flush with the bottom surface of the waste; when the upper surface of the floater 3 is flush with the top of the drainage ditch 2, the cross section of the floater 3 is matched with that of the drainage ditch 2, rainwater runoff enters from the inflow opening 1, and then overflows through the drainage ditch 2 and enters the water distribution area 31; when the upper surface of the float 3 is flush with the bottom of the drainage ditch 2, or when the upper surface of the float 3 does not exceed the set height of the cross section of the drainage ditch 2 (the set height should be not higher than 1/3 of the cross section of the drainage ditch 2), the rainwater runoff in the drainage ditch 2 is discharged to the sewage pipeline 6, and the initial rainwater drainage is realized.
Specifically, the bottom structure of the ecological tree pool in this embodiment includes a concrete layer 37, a sand layer 15 and a planting soil layer 14 from bottom to top, wherein the outflow area 33 does not have the bottom structure, and the outflow area 33 is an outflow well 17 structure. The stagnation space 13 is the upper space of the planting soil layer 14 in the whole tree pool, and has the main functions of stagnation and storage of rainwater runoff in the middle and later periods of the part. Planting soil layer 14 is located the below of float 3, and planting soil layer 14 function is planting georgette plant and utilizes soil medium to purify the rainfall runoff, and the inside filler of planting soil layer 14 can be according to actual engineering needs, fills different grade type filtering material and planting soil. The sandstone layer 15 is located below the planting soil layer 14. Concrete layer 37 provides support for the whole tree pool, and may be in the form of on-site brick and cement mortar plastering, or in the form of an integrally formed structure, and the material is cast iron, stainless steel or polyvinyl chloride.
The inflow port 1 is a water inlet structure for receiving surface runoff in the tree pool. In road applications, it is common for the curb to be open on one side of the road. The height of the inflow opening 1 is the same as the height of a road or slightly lower than the height of an urban road, and the main purpose is to effectively collect urban road rainwater runoff and enable the rainwater runoff to enter the ecological tree pool through the inflow opening 1.
The drainage ditch 2 is an important component for realizing the initial rainwater drainage function of the ecological tree pool. One end of the connecting pipe is connected with the flow inlet 1, and the other end is connected with the sewage pipeline 6. The elevation of one end of the drainage ditch 2 connected with the inflow opening 1 is not higher than that of the inflow opening 1, so that initial rainwater runoff and snow melting runoff can be enabled to flow into the drainage ditch 2. The other end of the waste drainage ditch 2 is connected with a sewage pipeline 6, and the elevation of the waste drainage ditch ensures that waste runoff can be smoothly discharged into the sewage pipeline 6. The form of the waste drainage ditch 2 can adopt on-site brick laying and cement mortar plastering, or adopt an integrally formed structure, and the material is cast iron, stainless steel, polyvinyl chloride or the like. The main function of the sewer line 6 is to drain the initial rain run-off and snow melt run-off of the waste stream.
The floater 3 is arranged at the middle section of the horizontal position of the waste water drainage ditch 2 (namely between the inflow port 1 and the sewage pipeline 6), and the floater 3 is in a cuboid, a cylinder or an elliptic cylinder shape. In a non-rainfall period, the floater 3 is positioned on the surface of the planting soil layer 14 right below the drainage ditch 2, and the upper surface of the floater 3 is level with the bottom surface of the drainage ditch 2; in a rainfall period, after rainfall lasts for a period of time, when the water content of the planting soil layer 14 reaches the saturated water content, the storage space 13 above the planting soil layer 14 starts to store water, runoff of rainwater stored in the storage space 13 is gradually accumulated, the floater 3 floats when the buoyancy is larger than the self gravity of the floater 3 until the upper surface of the floater 3 is flush with the top of the drainage ditch 2, water flow in the drainage ditch 2 is blocked, and at the moment, the drainage ditch 2 stops draining towards the sewage pipeline 6; the rainfall is gradually reduced to the end, the inflow is reduced to the complete stop, the water level of the runoff stored in the storage space 13 is also gradually reduced, the floater 3 is gradually reduced along with the reduction of the water level height until the floater 3 completely falls onto the surface of the planting soil layer 14, and the drainage ditch 2 recovers the drainage function again. The floater 3 can be made of plastics such as polyvinyl chloride and the like, has a hollow or solid structure, and can be ensured to float according to the design requirement.
The water distribution area 31 is the inner area of the solid container, and the main function of the water distribution area is to discharge the middle and later stage rainwater runoff after the flow discarding into the storage space 13 and the planting soil layer 14.
The shape of first through-hole in this embodiment is the same with float 3's shape, and the size of first through-hole slightly is greater than float 3's size, guarantees that float 3 can pass through first through-hole, and the gap between first through-hole and the float 3 is less than 1mm, adopts lower value as far as possible under the prerequisite of guaranteeing float 3 fluctuation, can set up waterproof leak protection material between first through-hole and float 3, avoids the rainwater to leak into to stagnate between the gap and hold space 13 and plant in soil layer 14.
When the upper surface of the float 3 is flush with the top of the drain 2, the float 3 is able to completely intercept the flow of water in the drain 2 towards the sewer line 6, i.e. the float 3 is able to completely cover the cross-section of the drain 2 at this time. Preferably, the cross section of the drainage ditch 2 is selected to be rectangular, the float 3 is also shaped like a cuboid, the first through hole is also shaped like a rectangle, when the float 3 rises from the first through hole to the top of the drainage ditch 2, rainwater cannot pass from the drainage ditch 2 into the sewage pipeline 6 due to the blocking effect of the float 3, at this time, a small amount of rainwater runoff which has entered the drainage ditch 2 (and is between the inflow port 1 and the float 3) is temporarily stored in the drainage ditch 2, and rainwater runoff which enters from the inflow port 1 enters the overflowing drainage ditch 2 into the water distribution area 31; after the rainfall is finished, the level of the rainwater runoff accumulated in the accumulation space 13 is reduced, the floater 3 falls back to the initial state, and a small amount of initial rainwater temporarily stored in the drainage ditch 2 between the inflow port 1 and the floater 3 is drained to the sewage pipeline 6 through the drainage ditch again.
According to the ecological tree pool and the working method, the float automatically controls the initial rainwater discarding flow, the automatic rainwater discarding flow is controlled through the automatic reset of the float 3 based on the rainfall degree, namely when the initial rainfall is small, the rainwater is discharged into the sewage pipeline 6 for discarding flow through the discarding flow drainage ditch 2, and when the middle and later rainfall is large, the discarding flow drainage ditch 2 is submerged and enters the water distribution area 31 for storage; continuously raining, wherein rainwater enters the accumulation stagnation space 13, so that the floater 3 floats upwards and blocks a flow path of the drainage ditch 2, and the rainwater is not drained at the moment; when the rainfall stops or gradually decreases, the rainwater level in the accumulation stagnation space 13 drops, the floater 3 sinks, and the drainage ditch 2 can play a role again to drain the rainwater. The invention solves the limitation of the traditional initial-stage flow abandoning facility based on volume control and flow control, the facility realizes automatic control through the floater 3, and the floater 3 automatically resets after a rain fall without manual operation, thereby greatly reducing the later-stage operation and maintenance requirements of the facility; through high-efficient abandoning class, realize that road catchment surface runoff initial stage runoff or snow melt runoff that particulate state pollutant concentration is higher abandon class to sewage conduit 6, effectively solved runoff initial stage pollutant probably lead to the tree pond in the operation jam, harm arbor this plant to and snow melt runoff to the influence scheduling problem of facility operation.

The overflow area 32 in this embodiment is arranged beside the water distribution area 31, and the grating 9 is provided with a grid for separating the water distribution area 31 from the overflow area 32 and mainly trapping large particle suspended matters and floating matters in inflow runoff. The grating 9 can be made of cast iron, stainless steel or polyvinyl chloride.

As shown in fig. 10 to 12, the present invention further discloses a working method of the ecological tree pool according to the above embodiment, including:
when there is no rainfall, the float 3 is positioned in the accumulation space 13 below the drainage ditch 2, and the upper surface of the float 3 is flush with the bottom surface of the drainage ditch 2;
when the rainfall is less than or equal to the maximum flow capacity of the drainage ditch 2, rainwater enters the drainage ditch 2 from the inlet port 1 and is discharged from the sewage conduit 6.
Specifically, as shown in fig. 10, in non-rainy days, the floats 3 are located above the planting soil 14, and the tops of the floats 3 are level with the bottoms of the drainage ditches 2, and the initial state is realized.
When the rainfall is larger than the maximum flow capacity of the drainage ditch 2, the rainwater flows through the drainage ditch 2 and enters the water distribution area 31 to permeate to the planting soil layer 14 and the sandstone layer 15 below the water distribution area 31.
Specifically, as shown in fig. 10, when rainfall is small, rainfall runoff after rainfall runoff occurs, rainwater runoff which is heavily polluted in the early stage is drained into the sewage pipe 6 through the drainage ditch 2. Along with the rainfall lasts, the initial stage rainwater is discharged from the tree pool, the flow of the inlet 1 of the tree pool is increased, and when the maximum overflowing capacity of the flow abandoning drainage ditch 2 is exceeded, rainwater runoff flows through the inlet 1 to flow through the flow abandoning drainage ditch 2 in a diffused mode, enters the area of the first perforated drainage plate 7, and through the second through holes, the runoff is dispersed to enter the stagnation storage space 13 and is infiltrated through the planting soil layer 14. However, due to the fact that rainfall is small, water cannot be stored in the upper layer of the planting soil (namely the storage space 13), the floater 3 is located above the planting soil layer 14 at the moment, the top of the floater 3 is level with the bottom of the drainage ditch 2, and the initial state is still achieved.
After the rainfall submerges the planting soil layer 14 and enters the stagnation space 13, the floater 3 floats upwards due to buoyancy and gradually rises from the first through hole, and finally the upper surface of the floater 3 is flush with the top surface of the drainage ditch 2, so that rainwater is prevented from being drained from the drainage ditch 2 to the sewage pipeline 6.
Specifically, as shown in fig. 11, when the rainfall continues and the water content of the planting soil layer 14 reaches saturation, the rainwater runoff starts to store water in the upper space (i.e., the stagnation space 13) of the planting soil layer 14, and as the water level inside the stagnation space 13 gradually rises, when the buoyancy is greater than the self-gravity of the float 3, the float 3 floats upwards along the predetermined track through the protrusion until the water level inside the stagnation space 13 does not rise any more, the float 3 stops sliding, but does not reach the top of the drainage ditch 2, and at this time, the brake plate 5 does not function, but the float 3 has exerted a certain function of blocking the water flow of the drainage ditch 2. The rainfall is gradually reduced to the end, the inflow is reduced to the complete stop, the water level of the accumulation space 13 is gradually reduced to the surface of the planting soil layer 14, the floater 3 also gradually falls to the surface layer of the planting soil along with the reduction of the water level line, and the floater 3 is reset to the initial state.
As shown in fig. 12, when rainfall is large, runoff in the early period after rainfall runoff is discharged to the sewage conduit 6 through the drainage ditch 2; along with continuous rainfall, the flow entering the tree pool inflow opening 1 is increased, when the maximum flow of the rainwater exceeds the maximum flow of the drainage ditch 2, the inflow of the rainwater flows through the inflow opening 1 and flows through the drainage ditch 2 in a diffused mode, the rainwater enters the area of the first perforated drainage plate 7, when the water content of the planting soil layer 14 reaches saturation, rainwater runoff begins to store water in an upper space (namely the stagnation space 13) of the planting soil layer 14, when the buoyancy of the floater 3 is larger than the self-gravity of the floater, the floater 3 slides upwards through the matching relation of the protruding blocks and the track, the floater 3 continuously slides upwards along with the continuous rising of the water level in the stagnation space 13, when the water level in the stagnation space 13 rises to a certain height, the floater 3 contacts with the brake block 5, the floater 3 does not float upwards, and at the moment, the upper surface of the floater 3 is level with the. As the rainfall continues, the inflow rate continues to increase, exceeding the drainage capacity of the second through-holes of the first perforated drain 7, the runoff carrying large particle pollutants and floating debris etc. into the area of the grille 9, the runoff passing through the grille 9 into the overflow area 32, through the second perforated drain 10 and the central inlet 12 into the stagnation space 13, while the large particle pollutants and floating debris etc. are intercepted by the grille 9 in the area of the first perforated drain 7.
Wherein, still include overflow area 32, water purification district 34 and outflow region 33:
when the rainfall is greater than the maximum overflowing capacity of the drainage ditch 2, the rainwater flows through the drainage ditch 2, flows to the water distribution area 31 and the overflow area 32 in sequence, and enters the tree pool planting area 35 in the water purification area 34 through the centralized inlet 12 of the overflow area 32;
when the rainfall is continuously increased, the water level in the accumulation space 13 rises, and when the water level exceeds the position of the overflow port 19, the water flows to the outflow area 33 from the overflow port 19 and is discharged through the rainwater pipeline 18;
when the rainfall is finished, the rainwater runoff stagnant in the stagnant storage space 13 permeates through the tree pool planting area 35, and the purified rainwater runoff is discharged into the perforated drain pipe 16 and finally enters the rainwater pipeline 18; as the water level in the accumulation space 13 falls, the float 3 falls along the rail, and the initial state before rainfall is restored, thereby realizing automatic reset.
Specifically, runoff after initial drainage enters the storage space 13 through the centralized inlet 12, the first perforated drainage plate 7 and the second perforated drainage plate 10, permeates into the planting soil layer 14 and the sand layer 15, is collected after filtration and purification, enters the perforated drainage pipe 16, and is then intensively discharged to the outflow well 17.
With the continuous rainfall, when the stagnation storage space 13 reaches the maximum stagnation storage capacity, the rainwater runoff flows continuously and flows in, and at the moment, the runoff is intercepted by the grating 9, overflows to the outflow well 17 through the overflow port 19 and finally flows into the rainwater pipeline 18. And the late rainfall is gradually reduced to the end, the inflow is reduced to the complete stop, the water level of the accumulation space 13 is gradually reduced to the surface of the planting soil layer 14, the floater 3 is also gradually reduced to the surface layer of the planting soil along with the reduction of the water level line, and the floater 3 is reset to the initial state.
The first cover plate 20, the second cover plate 22, the third cover plate 24 and the fourth cover plate 26 can be opened in the non-rainfall time to carry out operation and maintenance work of the ecological tree pool, the third cover plate 24 can be opened after 1-2 heavy rains generally, large-particle pollutants and floating garbage intercepted by the grating 9 are intensively cleaned, and the first cover plate 20, the second cover plate 22 and the fourth cover plate 26 can be opened once before and after a rainy season according to operation and maintenance needs to carry out necessary desilting, inspection and maintenance work.
It is worth noting that: the above "light rain", "medium rain" and "heavy rain" can be determined according to the local precipitation conditions, the "light rain bit line", "medium rain bit line" and "heavy rain bit line" in fig. 10 to 12 are schematic, and the water bit lines of the actual different precipitation conditions are determined by the factors such as the local precipitation amount, the scale of the tree pool and the size of the catchment surface of the receiving road.
