Description

A rainwater storage and purification system

technical field

The invention relates to the fields of water ecological restoration and rainwater isolation and regulation, in particular to a rainwater storage and purification system.

Background technique

In urban planning, drainage issues are very important, especially in cities with a lot of rainfall, if the rainfall cannot be effectively drained, adjusted and stored, it will cause floods, which will not only cause huge losses to the urban economy, but also damage the city. The surrounding environment causes damage; therefore, effective rainwater scheduling and storage can effectively reduce the economic loss of the city; at the same time, when regulating rainwater, it is also necessary to effectively purify the rainwater, and the untreated rainwater cannot be directly discharged to the river. In the process, the river water is polluted, so it is necessary to synchronously purify the rainwater while regulating the rainwater.

In the prior art, the methods for the isolation and storage of surface rainwater are divided into three types: peak flow adjustment and storage, non-point source pollution control adjustment and storage, and rainwater utilization adjustment and storage. Each method is generally applied in a single manner, and cannot well solve the synergistic relationship between the three. According to the survey, most of the existing isolated regulation and storage systems are a comprehensive regulation and storage tank, which cannot be combined with large areas, and the use is inflexible. The purification treatment of rainwater is mostly centralized treatment, which not only covers a large area, but also has complicated purification steps and high cost.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a rainwater regulation, storage and purification system in view of the above-mentioned problems; the present invention solves the problem of a single reservoir in the isolation regulation and storage system; It also solves the problem that the purified rainwater cannot be synchronized in the process of rainwater regulation.

The technical scheme adopted in the present invention is as follows:

A rainwater regulation, storage and purification system, comprising: regulation and storage water bodies and treatment pools; the regulation and storage water bodies and treatment pools are several in number, and the treatment pools are located in the regulation and storage water bodies and are connected to the regulation and storage water bodies for purifying rainwater; The water bodies are connected by a plurality of hidden pipes, the water inlet and outlet are symmetrically arranged on the regulating and storing water body, the water inlet and the water outlet extend into the treatment tank, and the hidden pipes are connected to the water inlet and the water outlet; The regulating and storing water bodies are arranged in different heights.

Due to the above structure, in the process of regulating and storing the rainwater by the regulating and storing water body, the rainwater can also be purified synchronously through the treatment tank arranged in the regulating and storing water body; After the rainwater reaches the position of the water outlet in the regulation and storage water body, the rainwater will flow out from the water outlet, reach another regulation and storage water body lower than the regulation and storage water body along the hidden pipe, and enter from the water inlet of the second regulation and storage water body to the water outlet. In the storage water body, the rainwater can be flexibly regulated.

Further, the treatment pond includes: a sedimentation pond, a wetland pond, a plant filter bed pond, a physical equipment pond and a stabilization pond; the sedimentation pond, the wetland pond, the plant filter bed pond, the physical equipment pond and the stabilization pond are located in different The adjustment and storage water bodies are connected in sequence, and the heights of the sections where they are located decrease in turn.

Further, the sedimentation tank is used for precipitating impurities in water; wetland ponds and plant filter bed ponds are used for improving water quality through plants and microorganisms; physical equipment ponds are used for purifying impurities in water by physical means; stabilization ponds are used for purifying purified water. Further impurity treatment is carried out so that the treated water can be discharged into the river.

Due to the above structure, rainwater will first enter the sedimentation tank located at a high place, and the sedimentation tank will settle the impurities in the rainwater, and then the sedimented rainwater will be transported to the wetland pond through the water outlet and the hidden pipe, and will pass through the wetland pond. The plants and microorganisms in the water can further decompose the harmful substances in the rainwater, and transmit the decomposed rainwater to the plant filter bed pool; the plant filter bed pool can increase the water content through the various aquatic plants planted in it. The oxygen content can also absorb the excess nutrients in the rainwater, so that algae will not grow in the water; and through the physical equipment pool on the next floor, the impurities in the rainwater can be further precipitated, filtered and absorbed. The water quality can reach the national standard; at this time, the rainwater after physical treatment is transferred to the stabilization pond. Through the stabilization pond, the water can be isolated from the outside world without causing secondary pollution, and the purified rainwater can be flexibly deployed.

Further, the water inlet is arranged on the side of the bottom of the regulating and storing water body; the water outlet is arranged on the side of the regulating and storing water body which is symmetrical with the water inlet.

Further, the water outlet includes a first water outlet and a second water outlet; the first water outlet is located on the side of the top of the regulating and storing water body, and the second water outlet is located on the side of the middle of the regulating and storing water body.

Due to the above structure, by setting two water outlets, the amount of water stored by the regulating and storage water body can be different in the rainy season and the dry season; if it is in the rainy season, when there is a lot of rainfall, the second water outlet will be opened, and when the rainwater enters the regulating and storage water body and the water volume When it reaches half of the capacity of the regulating and storing water body, the rainwater in the regulating and storing water body will be discharged to the next regulating and storing water body through the second water outlet, and it will not overflow or overflow due to excessive rainfall. Timely; when it is in the dry season and the rainfall decreases, the first water outlet will be opened and the second water outlet will be closed. At this time, the water in the adjustment and storage water body will be discharged to the next adjustment and storage water body when it is full. In this way, it can be ensured that in the season of low rainfall, sufficient rainwater can be accumulated, and there will be no shortage of water sources when water is urgently needed.

Further, the first water outlet and the second water outlet are located on the same side of the regulating and storing water body, and are symmetrical with the side where the water inlet is located.

Due to the above structure, the first water outlet and the second water outlet are on the same side of the regulating and storing water body, which can facilitate the opening and closing control of the two water outlets.

Further, the first water outlet and the second water outlet are respectively connected with dark pipes.

Due to the above structure, the two hidden pipes connected to the first water outlet and the second water outlet respectively will converge into one hidden pipe before reaching the water inlet of the next regulating and storing water body.

Further, there is a height difference between the regulating and storing water bodies at the same height.

Due to the above structure, by setting the height difference, the rainwater in the regulating and storing water bodies in the same section can be regulated.

Further, the regulating and storing water body, the treatment tank and the dark pipe are all arranged below the ground surface.

Due to the above structure, the regulating and storage water bodies and hidden pipes can be arranged below the surface without occupying surface resources. At the same time, the regulating and storage water bodies in some sections can adopt ornamental designs such as park ponds.

To sum up, due to the adoption of the above-mentioned technical solutions, the beneficial effects of the present invention are:

1. The present invention forms a complete rainwater purification system through different treatment ponds, so that the rainwater can be purified during the control process, which greatly reduces the steps of rainwater purification. Reduced construction costs.

2. In the present invention, by setting up a plurality of regulating and storing water bodies, the storage capacity of each regulating and storing water body can be adjusted mutually, which can effectively ensure the formation of living water between the water bodies, effectively isolate the regulating and storing water bodies from the external rivers and lakes, and also reduce the construction cost. The footprint of the reservoir reduces costs.

3. In the present invention, through two water outlets, the regulating and storing water body can jointly regulate the storage capacity in rainstorm or drought period, so as to prevent the storage body from exceeding the capacity or presenting the phenomenon of ebb and flow zone.
