Description

Technical Field

[0001] The utility model relates to the technical field of ecological retention ponds, in particular to a pollution interception ecological retention pond. Background Art

[0002] As an effective means of rainwater management and ecological restoration, ecological retention ponds are mainly divided into two categories: large-scale natural transformation ecological retention ponds and small-scale pure artificial ecological retention ponds according to their scale, construction method and functional orientation. Large-scale natural transformation ecological retention ponds usually rely on natural terrain and water bodies, and through appropriate artificial interventions, such as terrain adjustment, vegetation restoration and other measures, realize the natural retention, infiltration and purification of rainwater, aiming to maintain the regional water ecological balance and reduce urban flood disasters. In contrast, small-scale pure artificial ecological retention ponds pay more attention to flexibility and accuracy. They are completely designed and built by humans, and can customize the structure, size and ecosystem of the retention pond according to specific site conditions and usage requirements to adapt to different rainwater management goals and environmental beautification requirements.

[0003] Small-scale pure artificial ecological retention ponds, with their delicate design and efficient ecological functions, not only play an important role in urban rainwater management, but also provide an ideal platform for plant experiments and small flower cultivation. Such retention ponds usually have a special vegetation area for planting and observing various water-tolerant and purifying plants, such as reeds, cattails, etc., to study their growth characteristics and purification effects under different hydrological conditions. In addition, small-scale pure artificial ecological retention ponds are often used as experimental fields for flower cultivation. By simulating the water cycle and soil environment under natural conditions, they provide controllable experimental conditions for flower breeding, cultivation and pest control. This mode of combining practical application with scientific research not only promotes the continuous innovation of ecological retention pond technology, but also provides rich plant resources and scientific basis for urban greening and ecological construction.

[0004] Patent document CN212050742U discloses a smart ecological filter bed rural sewage treatment device, which relates to the field of ecological filter beds. The key points of its technical solution include an anoxic treatment tank for anoxic treatment of sewage, a sewage pump for sewage lifting, a treatment tower for anaerobic and aerobic treatment of sewage, an air pump for introducing air into the treatment tower, a monitoring device for real-time water quality monitoring, and an ecological pond for further treatment of water quality. A treatment tower for aerobic treatment is arranged at the front end of the ecological pond. During the treatment stage of the ecological pond, aeration is not required, only advection is needed, which can effectively avoid the situation of damaging the root fixing effect of vegetation by aeration under the ecological pond, improve the survival rate of vegetation, make the vegetation growth condition better, and to a certain extent, can also improve the water treatment effect.

[0005] In the prior art of the above-mentioned patent, the device is designed to effectively purify sewage through a built-in processing system, with the aim of achieving the recycling of water resources, especially showing significant advantages in supporting vegetation cultivation. Its core lies in a sewage treatment device integrated in the treatment tower, which can perform the task of water quality purification to ensure that the output water meets the needs of vegetation growth. However, during the actual operation, this design also exposes certain limitations. In particular, the filter component inside the treatment device, as a key part of the purification process, is prone to accumulating impurities due to being in a closed state for a long time. If these impurities are not removed in time, they will not only hinder the normal operation of the filter, reduce the purification efficiency, but also may have an adverse impact on the overall water quality. More troublesome is that since the filter component is fixed inside the treatment tower, the cleaning work becomes extremely complicated and time-consuming, increasing the maintenance cost and operation difficulty.
