The system comprises a water collecting part, a water purifying part and a water draining part which are mutually matched. The water collecting part comprises a water collecting tank. The water purifying part includes: the device comprises a water inlet pipe, a first filtering area, a second filtering area, a third filtering area and a fourth filtering area, a first water distribution ring, a second water distribution ring and a plurality of first blocking pieces. The drain portion includes: the first drain pipe, the second drain pipe, the communicating pipe, the linear effluent groove, the annular effluent groove, the first nutrition tank, the second nutrition tank and the third nutrition tank.
When the amount of rain water is small, the rain will enter the water collecting tank first and then flow into the first water distributing ring through the water inlet pipe 02. Because the inside wall of the first water distribution ring is attached to the first filtering area, rainfall evenly flows into the first filtering area after water distribution through the first water distribution ring. Because the first filtering area comprises a vegetation area, rainfall can be subjected to preliminary filtration through the first filtering area to filter out large-size impurities. Continuing, as each filtering area forms a circular ring structure, the outer side wall of the second water distribution ring is simultaneously attached to the inner side wall of each filtering area, and the preliminarily filtered rainwater flows into the second filtering area, the third filtering area and the fourth filtering area respectively through the second water distribution ring. Because the second filtering area comprises a gravel area, rainwater with small-size impurities is filtered by the second filtering area and enters the first nutrition tank to be stored water rich in nitrogen and phosphorus; because the third filtering area comprises a dephosphorization area, the rainwater filtered by the third filtering area enters the second nutrition tank to be rich in nitrogen; since the fourth filtration zone comprises a denitrification zone, the rainwater filtered thereby is introduced into the third nutrient tank as phosphorus-rich water. At this time, in practical application, the growth requirements of plants lacking different types of nutrients are satisfied. Meanwhile, the height of the outer side wall of the annular outflow slot is equal to the height of the inner side wall corresponding to the second filtering area and is larger than the height of the inner side wall corresponding to the third filtering area and the fourth filtering area; therefore, when each nutrition pot is full of water, rainwater passing through the second water distribution ring only enters the third filtering area and the fourth filtering area. And a nitrogen purifying area is arranged outside the dephosphorizing area of the third filtering area; and a phosphorus purifying area is further arranged at the outer side of the denitrification area of the fourth filtering area. Therefore, the rainwater flowing into the annular outflow groove is the rainwater subjected to denitrification and dephosphorization simultaneously. At this time, the rainwater is continuously discharged through the linear outflow groove and the second drain pipe. Therefore, when each nutrition pot is full, the rainwater can be discharged after the nutrients are thoroughly removed, so that the pollution to water for river channels, municipal administration and the like is avoided.
When the rainwater volume is great, because along the lateral wall of catch basin, the water inlet of communicating pipe is higher than the water inlet of inlet tube. Therefore, after precipitation enters the water collecting tank, the excess part can be rapidly discharged from the second drain pipe through the communicating pipe while being treated by the process. Avoiding the formation of surface water collection.
When the amount of rainwater is huge, the water inlet of the first drain pipe is higher than the water inlet of the communicating pipe due to the fact that the water inlet is along the side wall of the water collecting tank. Thus, precipitation is discharged through the second drain pipe and also directly in the sump through the first drain pipe. So as to relieve the drainage pressure of the second drain pipe and realize ultra-fast drainage.

In a specific arrangement, the first drain pipe 12 is vertically inserted into the water collecting tank 01, the second drain pipe 13 is vertically inserted into the inner side of the second water distribution ring 10, one end of the communicating pipe 14 is communicated with the water collecting tank 01, and the other end is communicated with the second drain pipe 13. The inner side wall of the annular outflow slot 16 is simultaneously and oppositely arranged with the outer side walls of the second filtering area 04, the third filtering area and the fourth filtering area, the linear outflow slot 15 is arranged between the first filtering area 03 and the second filtering area 04, and between the first filtering area 03 and the fourth filtering area, one end of the linear outflow slot 15 is communicated with the second drain pipe 13, and the other end is communicated with the annular outflow slot 16. The first nutrition pot 17 is communicated with the second filtering area 04, the second nutrition pot 18 is communicated with the dephosphorizing area 05, and the third nutrition pot 19 is communicated with the denitrification area 07. In terms of specific dimensions, along the side wall of the water collection tank 01, the water inlet of the first water discharge pipe 12 is higher than the water inlet of the communicating pipe 14, and the water inlet of the communicating pipe 14 is higher than the water inlet of the water inlet pipe 02; the height of the outer side wall of the annular outflow slot 16 is equal to the height of the inner side wall corresponding to the second filtering area 04 and is larger than the height of the inner side wall corresponding to the third filtering area and the fourth filtering area.
At this time, in practice, when the amount of rain water is small, the rain water enters the water collection tank 01 first, and then flows into the first water distribution ring 09 through the water inlet pipe 02. Since the inner side wall of the first water distribution ring 09 is attached to the first filtering area 03, rainfall flows into the first filtering area 03 uniformly after water distribution through the first water distribution ring 09. Because the first filtering area 03 includes a vegetation area, rainfall is primarily filtered in the first filtering area 03 to filter out large-size impurities such as dead branches, dead leaves, larger suspended particles, and the like. Continuing, as each filtering area forms a circular ring structure, the outer side wall of the second water distribution ring 10 is simultaneously attached to the inner side wall of each filtering area, and the preliminarily filtered rainwater flows into the second filtering area 04, the third filtering area and the fourth filtering area respectively through the second water distribution ring 10. Since the second filtering area 04 comprises a gravel area, rainwater with small-sized impurities is filtered by the second filtering area, and enters the first nutrition tank 17 to be water rich in nitrogen and phosphorus; since the third filtration zone comprises a dephosphorization zone, the stormwater filtered thereby enters the second nutrient tank 18 as nitrogen-enriched water; since the fourth filtration zone comprises a denitrification zone, the rainwater filtered thereby is introduced into the third nutrient tank 19 as phosphorus-rich water. At this time, in practical application, the growth requirements of plants lacking different types of nutrients are satisfied.
In this embodiment, the cross-sectional areas of the second filtering area 04, the third filtering area and the fourth filtering area are all equal; the depth is equal. The size of each nutrient tank is also equal. At this time, the amount of the primarily filtered rainwater entering each filtering area is the same, and the water storage amount stored in the corresponding nutrition pot is increased at the same time, so that the water is fully stored at the same time. So as to meet the requirements of various water storage to the greatest extent at the same time.
In order to smoothly drain the filtered rainwater into each nutrition pot, the bottom of the second filtering area 04 is communicated with the bottom of the first nutrition pot 17, and the bottom of the second filtering area 04 is higher than the bottom of the first nutrition pot 17. The bottom of the dephosphorization zone 05 communicates with the bottom of the second nutrient tank 18, and the bottom of the dephosphorization zone 05 is higher than the bottom of the second nutrient tank 18. The bottom of the denitrification region 07 is communicated with the bottom of the third nutrition pot 19, and the bottom of the denitrification region 07 is higher than the bottom of the third nutrition pot 19.
Meanwhile, since the height of the outer sidewall of the annular outflow groove 16 is equal to the height of the inner sidewall corresponding to the second filtering area 04 and is greater than the height of the inner sidewall corresponding to the third filtering area and the fourth filtering area; therefore, when each nutrition pot is full of water, rainwater passing through the second water distribution ring 10 only enters the third filtering area and the fourth filtering area. And a nitrogen purifying zone 06 is arranged outside the dephosphorizing zone 05 of the third filtering zone; the outer side of the denitrification area 07 of the fourth filtering area is also provided with a phosphorus purifying area 08. Therefore, the rainwater flowing into the annular outflow groove 16 is the rainwater subjected to the simultaneous denitrification and dephosphorization. At this time, the rainwater is continuously discharged through the linear type outlet groove 15 and the second drain pipe 13. Therefore, when each nutrition pot is full, the rainwater can be discharged after the nutrients are thoroughly removed, so that the pollution to water for river channels, municipal administration and the like is avoided.
When the amount of rainwater is large, the water inlet of the communicating pipe 14 is higher than the water inlet of the water inlet pipe 02 due to the side wall along the water collecting tank 01. Therefore, after precipitation enters the water collection tank 01, the excess part is rapidly discharged from the second drain pipe 13 through the communicating pipe 14 while being treated in the above-mentioned process. Avoiding the formation of surface water collection.
And when the amount of rainwater is large, the water inlet of the first drain pipe 12 is higher than the water inlet of the communicating pipe 14 due to the side wall along the sump 01. The precipitation is thus also discharged directly in the sump 01 via the first drain pipe 12 when it is discharged via the second drain pipe 13. So as to relieve the drainage pressure of the second drain pipe 13 and realize ultra-rapid drainage.
In summary, the system described in this embodiment can collect rainwater containing high concentration of nitrogen and phosphorus, rainwater containing phosphorus and rainwater containing nitrogen, so as to be used as fertilizer in practical application. Meanwhile, when different rainfall is achieved, rapid drainage can be independently carried out through different channels, accumulation of surface runoff water is avoided, life and travel of people are facilitated, and adverse effects on plant growth are avoided. Meanwhile, the system of the embodiment also creates a unique-modeling rural landscape environment through the mutual matching of the water collecting part and the water purifying part in structural design, and is more suitable for the construction of beautiful villages.
In order to further achieve uniform water distribution, the water inlet pipe 02 comprises a first water inlet pipe and a second water inlet pipe, and the first filtering area 03 is positioned at one side close to the water collecting tank 01. At this time, one end of the first water inlet pipe and one end of the second water inlet pipe are both communicated with the water collecting tank 01, and the other ends of the first water inlet pipe and the second water inlet pipe are respectively tangent to and communicated with the first water distribution ring 09.
Specifically, the dephosphorization zone 05 and the phosphorus purification zone 08 are filled with aluminum sludge composite filler, and the aluminum sludge composite filler is prepared by firing uniformly mixed aluminum sludge, zeolite and steel slag. The filler contains a large amount of aluminum ions and has a larger specific surface area, so that the adsorption removal of phosphorus can be enhanced; further has good dephosphorization effect.
The denitrification region 07 and the nitrogen purification region 06 are filled with immobilized bacteria and algae fillers, wherein the immobilized bacteria and algae fillers comprise fungus fillers and algae fillers; the fungus filler comprises anaerobic bacteria and aerobic bacteria, and the algae filler comprises chlorella pyrenoidosa powder or/and chlorella microcystis powder. At this time, the immobilized bacteria algae pellets have high biological activity strains, so that the immobilized bacteria algae pellets have high pollutant removal efficiency in the early stage, and the formation and growth of the peripheral filler biological film can be promoted due to the high-efficiency strains, so that the growth time of the biological film is relatively shortened. The high polymer material shell of the immobilized bacteria and algae has stronger water absorption and water permeability, and when the traditional filler is blocked, sewage can still flow out through the immobilized pellets; the immobilized shell limits the bacteria and algae within a certain range, thereby avoiding any growth of biological films and reducing the replacement frequency of the immobilized bacteria and algae filler layer.
In order to avoid that the packing in each filtering zone is mutually penetrated, thereby influencing the filtering effect, the system is provided with a plurality of second barriers 20, and a plurality of through holes are arranged on the second barriers 20. The inter-permeation influence of the stuffing is blocked, and the inter-communication of the filtered water in the third filtering area and the fourth filtering area is ensured. In this embodiment, the second blocking member 20 is also a partition plate. As another specific embodiment, a notch may be provided at the bottom of the partition.
In a specific implementation, the top parts of the first water distribution ring 09 and the second water distribution ring 10 are both in an opening structure so as to be communicated with the external environment; on one hand, the oxygen content in the rainwater is increased, so that the organic matter degradation and ammoniation nitration process of the rainwater are promoted.
In this embodiment, the top of the annular outflow slot 16 is an opening structure to communicate with the external environment, so as to prevent the rainwater from being isolated from the air, thereby breeding mosquitoes and being polluted again. The linear outlet grooves are buried underground, so that rainwater to be discharged is prevented from entering each filtering area again.
To facilitate access to the stored water in each of the nutrition cans, a plurality of suction pipes 21 are provided. The suction pipes 21 are vertically inserted into the first, second and third nutrient tanks 17, 18 and 19 in a one-to-one correspondence.
While the invention has been described with reference to preferred embodiments, it is not intended to be limiting. Those skilled in the art will appreciate that various modifications and adaptations can be made without departing from the spirit and scope of the present invention. Accordingly, the scope of the invention is defined by the appended claims.
