Although sewage is treated by a sewage treatment plant, the treated reclaimed water still contains a small amount of pollutants, and the treated reclaimed water still generates pollution after being discharged into rivers and lakes.
The polder is a special irrigation terrain developed in the south of China and is commonly used for planting rice. The artificial dyke is built by artificial dykes and ridges to form one or more flood dykes or irrigation dykes which encircle farmlands, and the flood dykes or irrigation dykes are usually formed at the edges of river channels, river bays or depressions and are connected with natural water systems.
The purification treatment of water entering the lake and sea by utilizing the wetland is a scheme which is gradually developed in recent years, such as a method for constructing the estuary water purification type wetland and a wetland system thereof disclosed in CN115745186A (2023.03.07 of publication), and the effect of the water quality strengthening and purifying function under the condition of limited space and residence time is ensured by diversion of a diversion submerged dike and multistage pond joint control, so that the method can be suitable for the water quality strengthening and purifying treatment of the estuary wetland with deeper water depth and short residence time; in addition, as disclosed in CN214883381U (publication date 2021.11.16), the small micro wetland structure of the pond is characterized in that the pond, the pond and the ditch are reasonably distributed from top to bottom along the mountain land topography, so that a coherent and complete water ecology system integrating functions of guiding, storing, filling and discharging is formed, the geographic topography, natural materials and natural rainfall are fully utilized, and the organic unification of production, living and ecology of the mountain land region is realized. In addition, CN202111633562.6 (publication date 2022.04.15) discloses a system and a method for repairing functions of a wetland under flood storage constraint of a estuary region, which reforms the estuary wetland, is communicated with a water system through terrain reforming, breaks the separation between regions, reduces dead water regions, is favorable for smooth water flow when the estuary region is used for storing flood, constructs a multi-field running water chain wetland through a reinforced purification region, increases ecological diversity of the estuary wetland, purifies water quality through denitrification and dephosphorization, repairs ecological functions of the estuary wetland, improves self-adaption, self-recovery and self-adjustment capabilities of the estuary wetland through a natural essence region, and greatly improves ecological elasticity of the estuary wetland.
However, the scheme has higher dependence on the topography, is arranged in a river mouth area, utilizes river water to promote water to flow, or is arranged in a mountain area, utilizes large fall to realize natural flow of water, and a levee is generally positioned in a plain area, has flat topography, extremely small entrance and exit fall, and is extremely slow in water flow in the levee due to the influence of aquatic plants, and most of the scheme is divided into mutually-non-communicated continuous ponds due to the activities of cultivation, planting and the like, so that the exchange amount of large-scale water such as rivers is extremely small, and the scheme is difficult to directly use for purification treatment of water quality entering lakes and sea water.
Accordingly, there is a need to provide an improved solution to the above-mentioned deficiencies of the prior art.
