Description

Technical Field

[0001] The present invention belongs to the technical field of ecological restoration, and in particular relates to a distributed purification system and method for sandy ecological environment restoration. Background Art

[0002] Due to its poor soil, lack of water and sparse vegetation, the sandy ecological environment is prone to land degradation and desertification, which seriously affects the ecological balance and human production and life. In the field of sandy ecological environment restoration, traditional restoration methods often rely on a large amount of artificial intervention and physical measures, such as afforestation and the establishment of protective forest belts. Although these methods can improve the sandy environment to a certain extent, they have the problems of high cost, slow effect and difficulty in long-term maintenance. Especially in the sandy environment with unstable rainfall, the lack of effective real-time monitoring and response mechanism has greatly affected the restoration effect. Most of the existing sand restoration systems fail to make full use of rainfall resources and lack the ability to dynamically adjust restoration measures according to rainfall. At the same time, there is often a lack of efficient separation and utilization methods for the treatment of rainwater and sand and stone mixtures produced during rainfall. This not only wastes precious rainwater resources, but may also aggravate the problem of soil erosion in sandy areas and cause further damage to the ecological environment. Summary of the invention

[0039] It can be understood that the design of the collection chamber and the separation assembly 105 in this embodiment realizes multi-stage separation and purification of the mixture of rainwater and sand and gravel, and improves the processing efficiency and effect. In particular, the separation assembly realizes intermittent alignment of the flow holes (flow hole 2 1053 and flow hole 4 1057) through the design of the rotating disc body, further improving the separation accuracy.

[0040] Combination Figure 5 Further preferably, a pedal 11 for fixing the hollow pin 12 is provided on the side of the box, and a plurality of drainage ports 121 are provided on the side of the hollow pin 12.

The pipe 106 is connected, a filter is arranged in the injection pipe 106 to prevent sand and gravel from entering the injection pipe 106), and an electric heating component is arranged in the upper horizontal section (an electric heating plate can be selected to dry the sand and gravel in the upper horizontal section); in specific implementation, the large-particle sand and gravel collected in the collection chamber 102 and the rainwater enter the first horizontal section of the branch pipe 2 108, the rainwater enters the injection pipe 106 through the branch pipe 3 109, the sand and gravel enter the upper horizontal section through the bending section, and then enter the delivery component 16 after being dried.

[0042] During the implementation of the scheme, when the monitoring terminal 2 detects rainfall, if the rainfall exceeds the set value, the control unit in the monitoring terminal 2 sends a command to the purification terminal 1 to start the collection chamber to collect a mixture of rainwater and sand and gravel. Subsequently, the sand discharge component 15 starts to work and discharges the sand and gravel out of the system. At the same time, the separation component 105 is started to achieve efficient separation of rainwater and sand and gravel through the rotation of the rotating disc and the intermittent alignment of the flow hole. The separated rainwater enters the storage and utilization system for subsequent use. At the same time, if the environmental parameters meet the delivery conditions, the control unit sends a command to the ecological restoration agent delivery component 16 to deliver the ecological restoration agent to the sand through the hollow pin 12.

[0043] In this embodiment, the monitoring terminal 2 is deployed in different areas of the sand, and a high-precision rainfall sensor is used to monitor the rainfall in real time, and the data is transmitted to the purification terminal 1 by wireless or wired means.

The purification terminal 1 includes a collection chamber (collection chamber 1 102 and collection chamber 2 104), a sand discharge component 15, a separation component 105 and a rainwater storage and utilization system. The collection chamber is responsible for receiving a mixture of rainwater and sand and gravel, the sand discharge component 15 discharges the sand and gravel, and the separation component 105 uses a rotating disc and other mechanisms to achieve efficient separation of rainwater and sand and gravel.
