[0030] Please refer to Figure 1 , Figure 2 , and a pond wetland system provided by the embodiments of the present invention will be described below.

[0031] A pond wetland system according to an embodiment of the present invention includes a wetland pond 1 and a habitat dike 2. The wetland pond 1 is provided with an inlet and an outlet; two adjacent habitat dikes 2 are respectively connected to the opposite inner side walls of the wetland pond 1, 0.5d < the length of each habitat dike 2 < d, where d is the distance between the opposite inner side walls of the wetland pond 1 to which the habitat dike 2 is connected; the habitat dike 2 includes a plurality of spaced-apart bird habitat dikes 21, benthic animal habitat dikes 22, and amphibian habitat dikes 23; a plurality of bird nests are provided on the bird habitat dike 22; cobblestones, such as pebbles, gravel, etc., can be laid on the benthic animal habitat dike 23; and emergent plants 32 are planted on the benthic animal habitat dike 22; grass seeds are sown on the amphibian habitat dike 23; the plurality of habitat dikes 2 divide the wetland pond 1 into a plurality of zones; submerged plants 31 are planted in the plurality of zones.

[0032] Aquatic plants 3 are planted in the wetland pond 1 of the embodiments of the present application. The aquatic plants 3 include submerged plants 31 and emergent plants 32. For example, submerged plants 31 are planted in the plurality of zones of the wetland pond 1, and different submerged plants 31 can be planted in different zones; emergent plants 32 are planted on the plurality of benthic animal habitat dikes 22 in the wetland pond 1, and emergent plants 32 can also be planted on the slopes of the wetland pond 1, and the plant density is 15 plants / m 2 ~30 plants / m 2 . In addition, different types of submerged plants 31 can be matched in adjacent zones of the wetland pond 1, and the density is 70 clusters / m 2 ~90 clusters / m 2, the emergent plants 32 can be at least one of calamus, wild rice stem, umbrella plant, canna, and pickerelweed. The emergent plants 32 provide a habitat for mollusks. The submerged plants 31 can be at least one of Vallisneria natans, Hydrilla verticillata, and Myriophyllum verticillatum.

[0033] In the embodiment of the present application, by limiting 0.5d < the length of each habitat dike 2 < d, the water flow path is extended, so that the pollutants in the water body are fully purified, and the purification effect is improved.

[0034] Multiple bird nests with a diameter of 20 - 30 cm can be set on the bird habitat dike 21. The bird nests are paved with hay bales for birds to inhabit and reproduce.

[0035] The seeding amount of grass seeds sown on the amphibian habitat dike 23 is: the grass seed amount per square meter is 20 g - 30 g. The amphibian habitat dike 23 can provide a habitat for amphibians such as frogs and lizards.

[0036] The multiple habitat dikes 2 provided in the wetland pond 1 in the embodiment of the present application have two main functions: the first function is to extend the water flow path so that the pollutants in the water body are fully purified; the second function is to provide a biological habitat for birds, benthic animals, and amphibians, enhancing the species diversity of the area.

[0037] Most existing pond wetland systems have no habitat at the water surface, or only provide a habitat island or related area for a single species such as birds, without considering the habitat needs of multiple species, or the habitat area does not consider the wetland purification needs of the entire wetland system. However, a pond wetland system of the present utility model uses multiple habitat dikes 2 to divide the wetland pond 1. On the one hand, the division by multiple habitat dikes 2 can extend the water body flow in the wetland pond 1, enhance the reduction effect of the wetland pond on nitrogen and phosphorus pollutants in sewage, and improve the water quality purification effect; on the other hand, the multiple spaced bird habitat dikes 21, benthic animal habitat dikes 22, and amphibian habitat dikes 23 can provide functional areas for the habitat and reproduction of multiple species such as birds, benthic animals, and amphibians. On the basis of water body purification, the species diversity in the area of the wetland pond 1 is further improved, which is beneficial to further improving the ecological environment quality of the wetland pond 1.

[0038] A pond wetland system of the present utility model combines the extension of the water body flow process with the function of increasing the habitat of multiple species by using multiple habitat dikes 2, improves the water quality purification effect while enhancing the species diversity in the area of the wetland pond 1, and is more beneficial to improving the ecological environment quality of the wetland pond 1.

[0039] In an embodiment of the present utility model, the wetland pond 1 is rectangular, with a length of 30 m - 50 m, a width of 15 m - 25 m, the ratio of length to width is 1:1.5 - 1:2, the depth is 1.5 m - 2 m, and the slope ratio of the slope is 1:1.5 - 1:2.

[0040] In one embodiment of the utility model, the habitat embankment 2 is perpendicular to the long side of the wetland pond 1 and parallel to the short side of the wetland pond 1. The length of the habitat embankment 2 is 80% of the long side of the wetland pond 1. The width of the habitat embankment 2 is 1 meter to 1.5 meters. The height of the habitat embankment 2 is higher than the highest water level of the wetland pond 1. Generally, the height of the habitat embankment 2 is 0.5 meters higher than the highest water level of the wetland pond 1.

[0041] In one embodiment of the present invention, the interval between two adjacent habitat dikes 2 is 4 to 6 meters, dividing the wetland pond 1 into 6 to 10 partitions.

[0042] In one embodiment of the utility model, a water gate 4 is provided at both the water inlet and the water outlet, and the water gate 4 includes a water inlet gate 41 and a water outlet gate 42, which are used to control the discharge or inflow of water in the wetland pond 1. The water inlet and the water outlet can be respectively arranged at the middle position of the two opposite short sides of the wetland pond 1, so that the water flow in the wetland pond 1 is longer and the water purification effect is improved.

[0043] In one embodiment of the present invention, a liquid level sensor 5 is provided in the wetland pond 1. The liquid level sensor 5 can be vertically installed in the wetland pond 1 to collect water level data in the wetland pond 1 in real time.

[0044] In one embodiment of the utility model, a pond and weir wetland system of the utility model also includes an automatic control device, which includes a single-chip microcomputer 6, a communication device 7 and a server 8. The single-chip microcomputer 6 is electrically connected to the liquid level sensor 5 and the communication device 7; the single-chip microcomputer 6 is used to convert the analog signal of the water level data monitored by the liquid level sensor 5 into a digital signal, and transmit the water level data to the communication device 7; the communication device 7 sends the water level data to the server 8; the server 8 receives the water level data, and in combination with the water level data and the time requirements for water purification, regulates the opening of the sluice gate 4 to realize the irrigation or drainage of the wetland pond 1. The communication device 7 can use a GPRS wireless communication module to send the digital signal of the water level data transmitted by the single-chip microcomputer 6 to the server 8 for storage and processing; the server 8 first stores the received water level data in the background, and then calls it to the processor for calculation and processing.

[0045] The specific use process of a pond and weir wetland system of the utility model is as follows: when the utility model is in operation, the high-nitrogen and phosphorus sewage to be treated enters the wetland pond 1 through the water inlet gate 41; the liquid level sensor 5 measures the water level in the wetland pond 1, processes the data through the single-chip computer 6, and the communication device 7 sends the water level data to the server 8; the server 8 stores and calls the water level data in real time, and when the water body continues to flow in and does not reach the normal water level of the wetland pond 1, the water inlet gate 41 is controlled to be opened and the water outlet gate 42 is closed; when the water level data reaches the wetland pond 1, the water level data is sent to the server 8; the server 8 stores and calls the water level data in real time, and when the water body continues to flow in and does not reach the normal water level of the wetland pond 1, the water inlet gate 41 is controlled to be opened and the water outlet gate 42 is closed; when the water level data reaches the wetland pond 1, the water level data is sent to the server 8; the server 8 stores and calls the water level data in real time, and controls the water level data to be sent to the server 8; when the water body continues to flow in and does not reach the normal water level of the wetland pond 1, the water level data is sent to the server 8; when the water level data reaches ... When the water level in pond 1 is at the normal level, server 8 controls the water inlet gate 41 and the water outlet gate 42 to be closed; when the water level reaches the normal water level for more than 36 hours, server 8 controls the water inlet gate 41 to be closed and the water outlet gate 42 to be opened, so that the purified water in wetland pond 1 is completely discharged; when there is no water level value in wetland pond 1, server 8 controls the water inlet gate 41 to be opened and the water outlet gate 42 to be closed, so that the next batch of polluted water flows into wetland pond 1, so that the water level in wetland pond 1 reaches the normal water level again, and a water purification process is completed.

[0046] In addition, the parts not described in detail above are all prior art.

[0047] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
