Description

Technical Field

[0001] This utility model belongs to the field of ecological water replenishment technology, and in particular relates to an in-situ ecological water replenishment system for a closed water system. Background Technology

[0002] Closed water systems are also carriers of water resources and an important component of the ecological environment. With economic development and water resource utilization, it is necessary to add ecological water replenishment measures on the basis of pollution source control to improve water flow, increase water environmental capacity and self-purification capacity, and enhance the effect of water environment improvement. Ecological water replenishment is an important technical means in the management of closed water systems. Currently, most water replenishment sources utilize reclaimed water from water purification plants to supplement closed water systems to maintain water volume and improve the ecological environment and function of closed water systems. However, reclaimed water still contains a certain amount of floating and suspended solids, requiring a longer self-purification time for closed water systems, which is not conducive to water resource utilization. Summary of the Invention

[0003] In view of this, the present invention aims to propose an in-situ ecological water replenishment system for closed water systems to solve the problem that floating and suspended solids in reclaimed water require a longer time to self-purify when added to closed water systems, which is not conducive to the utilization of water resources.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] An in-situ ecological water replenishment system for a closed water system includes a first sedimentation tank, a second sedimentation tank, a closed water system, a first retaining wall, and a second retaining wall. The second sedimentation tank is located to the right of the first sedimentation tank, and the closed water system is located to the right of the second sedimentation tank. A first retaining wall is provided between the first sedimentation tank and the second sedimentation tank, and a second retaining wall is provided between the second sedimentation tank and the closed water system.

[0006] Furthermore, the first sedimentation tank is provided with a first slope on both sides, and a flexible ecological protective layer is laid from the first slope to the bottom of the first sedimentation tank.

[0007] Furthermore, the flexible ecological protective layer includes a first geotextile layer, a plastic layer, a second geotextile layer, and a pebble layer. The first geotextile layer is laid from the first slope to the bottom of the first sedimentation tank. The plastic layer is laid on top of the first geotextile layer, the second geotextile layer is laid on top of the plastic layer, and the pebble layer is laid on top of the second geotextile layer.

[0008] Furthermore, a second slope is provided on both sides of the second sedimentation tank, on which emergent aquatic plants are planted, and a bottom mud layer is laid at the bottom of the second sedimentation tank, on which several lotus flowers are planted.

[0009] Furthermore, the first and second retaining walls are constructed of hard stones, with the first retaining wall being higher than the second retaining wall, and the second retaining wall being higher than the water level of the enclosed water system. The second retaining wall is waterproofed.

[0010] Compared with existing technologies, the in-situ ecological water replenishment system for closed water systems described in this utility model has the following advantages:

[0011] The in-situ ecological water replenishment system for closed water systems described in this utility model has a simple structure and strong practicality. It can effectively maintain the water volume of closed water systems, improve the ecological environment and function of closed water systems, and intercept and purify floating and suspended matter in the replenishment water before it enters the closed water system. This reduces pollutants entering the closed water system from the source, reduces the self-purification time of the closed water system, facilitates the utilization of water resources, and also has certain ornamental value.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-3 As shown, an in-situ ecological water replenishment system for a closed water system includes a first sedimentation tank 1, a second sedimentation tank 2, a closed water system 3, a first retaining wall 4, and a second retaining wall 5. The second sedimentation tank 2 is located to the right of the first sedimentation tank 1, and the closed water system 3 is located to the right of the second sedimentation tank 2. A first retaining wall 4 is provided between the first sedimentation tank 1 and the second sedimentation tank 2, and a second retaining wall 5 is provided between the second sedimentation tank 2 and the closed water system 3. The first sedimentation tank 1 and the second sedimentation tank 2 are 20-25m long, 10m wide, and 1.5-2m deep. The function of the first sedimentation tank 1, the second sedimentation tank 2, the first retaining wall 4, and the second retaining wall 5 is to reduce pollutants entering the closed water system from the source.

[0023] The first sedimentation tank 1 is provided with a first slope protection 11 on both sides, and a flexible ecological protective layer 12 is laid in the first sedimentation tank 1 from the first slope protection 11 to the bottom of the first sedimentation tank 1.

[0024] The flexible ecological protective layer 12 includes a first geotextile layer 121, a plastic layer 122, a second geotextile layer 123, and a pebble layer 124. The first geotextile layer 121 is laid from the first slope protection 11 to the bottom of the first sedimentation tank 1. The plastic layer 122 is laid on top of the first geotextile layer 121, the second geotextile layer 123 is laid on top of the plastic layer 122, and the pebble layer 124 is laid on top of the second geotextile layer 123. The flexible ecological protective layer 12 is laid for a total length of 20-30 cm. The plastic layer 122 is a plastic film with a diameter of 10 mil or more, and the pebble layer is pebbles with a particle size of 10-20 cm. At the same time, the pores of the pebbles can intercept some of the suspended particles that are settled.

[0025] The second sedimentation tank 2 has second slopes 21 on both sides, on which emergent aquatic plants are planted. The bottom of the second sedimentation tank 2 is covered with a bottom mud layer 22, on which several lotus flowers are planted at a density of 9 plants / m². 2 The lotus root system can effectively stabilize the bottom mud layer22, which can prevent the water from becoming turbid due to upstream water flow. The lotus stem can effectively block floating objects and also has high ornamental value.

[0026] The first retaining wall 4 and the second retaining wall 5 are made of hard stones. The first retaining wall 4 is higher than the second retaining wall 5, and the second retaining wall 5 is higher than the water level of the closed water system 3. The first retaining wall 4 and the second retaining wall 5 are waterproofed. The first retaining wall 4 and the second retaining wall 5 serve to intercept the water flow.

[0027] When this utility model is in operation: the replenishment water source flows from the first sedimentation tank 1 into the second sedimentation tank 2, and finally enters the closed water system 3. After passing through the flexible ecological protective layer 12 in the first sedimentation tank 1, the replenishment water source will have a certain amount of floating and suspended matter reduced under its action. Then, after passing through the second sedimentation tank 2, the floating and suspended matter in the replenishment water source will be further reduced under the purification and interception of the lotus flowers, thereby achieving the effect of purifying the replenishment water source from the source. The first retaining wall 4 is higher than the second retaining wall 5, and the second retaining wall 5 is higher than the water level of the closed water system 3, which plays the role of an overflow weir. The replenishment water source can smoothly enter the closed water system, improving the ecological environment and function of the closed water system.

[0028] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the utility model should be included within the protection scope of the utility model.
