Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to an aquatic plant sewage treatment device. Background Art

[0002] With the rapid development of industrialization and urbanization, water pollution is becoming increasingly serious, especially eutrophication of water bodies, which has become a global environmental problem. Eutrophication not only leads to water quality deterioration and affects the balance of aquatic ecosystems, but also poses a threat to human health. In order to effectively control water pollution, traditional physical and chemical methods can remove pollutants to a certain extent, but they are often costly and may cause secondary pollution. Therefore, it is particularly important to find an economical, environmentally friendly and efficient water purification technology.

[0003] In recent years, ecological floating island technology, as a new water purification method, has attracted widespread attention due to its good purification effect, low maintenance cost, and strong landscaping function. Ecological floating islands mainly use the absorption and adsorption capacity of the roots of aquatic plants or terrestrial plants to effectively reduce nutrient-rich substances such as nitrogen and phosphorus in the water. At the same time, the biofilm on the surface of the plant roots can further decompose organic pollutants and accelerate their degradation process, thereby achieving water purification. However, the existing ecological floating island technology still has some shortcomings in the application process, such as the stability of the floating island board, the beautification effect, and the convenience of movement, which need to be improved.

[0004] First of all, the stability of the floating island board is the key to ensure the normal operation of the ecological floating island. Traditional floating island boards often use simple buoyancy structures and lack effective limiting measures, which makes them prone to displacement or even capsizing in strong winds and waves, affecting the purification effect.

[0005] Secondly, beautification effect is an important consideration for ecological floating islands as landscape facilities. Existing floating island panels often only focus on purification functions and ignore the beautification of the surrounding environment. They lack artistic sense and ornamental value and are difficult to coordinate with the surrounding landscape.

[0006] Finally, mobility is crucial to the application scope and flexibility of ecological floating islands. Traditional floating islands often lack convenient mobility mechanisms. A large number of aquatic plants are planted on the floating islands, which are heavy overall. As a result, a lot of manpower and material resources are required to drag and move them when changing positions, which is relatively time-consuming and labor-intensive, increasing the cost of use.

[0007] In response to the above problems, the present invention proposes an improved aquatic plant sewage treatment device, which aims to improve the stability, beautification effect and mobility of the floating island board through innovative design and technical means, thereby further enhancing the water purification capacity and practical application value of the ecological floating island.

The root of each aquatic plant pot 2 is immersed in the water, and the nitrogen, phosphorus and other nutrient-rich substances in the water body are effectively reduced through the absorption and adsorption capacity of the roots of aquatic plants or terrestrial plants. These plants convert nitrogen, phosphorus and other nutrients in the water body into the plant's own biomass through the absorption action of the roots, thereby reducing the concentration of nutrients in the water body and alleviating the eutrophication of the water body. In addition to nutrient-rich substances, the ecological floating island can also remove organic pollutants in the water body. The biofilm attached to the surface of the plant roots contains a large number of microorganisms such as bacteria and protozoa.

During the detection, the detection module 72 composed of a total phosphorus sensor, an ammonia nitrogen sensor and a turbidity sensor detects the total phosphorus content, ammonia nitrogen content and turbidity of the water quality, and converts the detection data into an electrical signal and sends it to the control mainboard. The control mainboard processes and analyzes the data, and sends it to the external control terminal through the wireless transmission module, so that the water quality can be understood in real time to prevent the water quality from deteriorating. The detection module 72 is installed in a protection box 73, and a filter screen 71 is set at the opening to prevent floating garbage in the water from entering and affecting the detection, thereby maintaining the safety of the detection;

[0045] In order to improve the beautification of the floating island board 1, the four groups of expansion drive devices 3 can be controlled to unfold to provide installation positions for installing beautification items. The external control terminal sends instructions, and the control main board receives the instructions through the wireless transmission module, and controls the four groups of drive structures 31 to work, that is, the steering engine starts to drive the connecting plate 32 to rotate 90 degrees in the right-angle groove 35 and stop working, unfold the folding expansion bag 34, and then control the inflation and deflation pump to inflate, and input compressed air into the inflation chamber 342 of the folding expansion bag 34 to expand it, thereby increasing the overall buoyancy of the floating island board 1.
