Abstract
Description
Technical Field
[0001] This utility model relates to the field of water environment management equipment technology, and in particular to a river ecological water purification device. Background Technology
[0002] With the acceleration of urbanization, the substandard discharge of large amounts of domestic sewage and industrial wastewater has led to severe eutrophication of urban rivers and canals, resulting in black and smelly water, damaging the aquatic ecological environment, and affecting the urban landscape and the quality of life of residents.
[0003] Currently, the main methods for treating river water bodies include physical dredging, chemical flocculation, and chemical oxidation. While these methods are effective quickly, they also have drawbacks such as high cost, potential for secondary pollution, and damage to the original ecosystem. In recent years, ecological restoration technologies have been widely used due to their environmental friendliness and sustainability. Common ecological purification measures include planting aquatic plants in the river and introducing microbial agents.
[0004] However, the ecological purification measures of planting aquatic plants in rivers have the following disadvantages: 1. For heavily polluted rivers, the treatment capacity of plant roots and microbial films alone is limited, making it difficult to quickly improve water quality; 2. The location of aquatic plants is fixed, and once damaged, they need to be cleaned up, which is difficult to do, and the plant configuration cannot be flexibly adjusted according to seasonal changes; 3. Aquatic plants are submerged by the ebb and flow of tides, making them difficult to keep alive and affecting aesthetics. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a river ecological water purification device to solve the above difficulties.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a river ecological water purification device, comprising a main frame floating on the water surface, multiple support rods at the edge of the main frame, a filter platform fixedly mounted on the top of each support rod, multiple recessed filling spaces on the upper surface of the filter platform, and filter packing structures filled in the filling spaces; multiple flower pots on the surface of the filter packing structures, with aquatic plants planted in the flower pots; and a circulating water system, comprising a controller, a water pump, a suction head, and multiple filter nozzles. The controller and water pump are respectively located on the bank, the water pump inlet is connected to a pumping pipe extending below the water surface, and the suction head is installed on the pumping pipe, with a water quality sensor installed on the suction head; the water pump outlet is connected to an outlet pipe extending above the flower pots, the outlet pipe has multiple branch outlets, and each filter nozzle is installed at each branch outlet, with each filter nozzle vertically aligned with a corresponding flower pot.
[0007] In a further technical solution, the inner side of the frame body is provided with multiple vertically penetrating frame openings, each of which is filled with floating filler material to form a floating filter structure.
[0008] In a further technical solution, the bottom of the flowerpot is provided with a drainage hole structure, and the inside of the flowerpot is filled with ceramic pebbles, with the roots of aquatic plants implanted in the ceramic pebbles inside the flowerpot.
[0009] In a further technical solution, the filter nozzle includes a cylindrical nozzle body, with a threaded connecting pipe at the top and a drip pipe at the bottom. The drip pipe outlet is sealed with a bottom cover, which has a mesh structure. The interior of the nozzle body consists of a ceramic granule layer, a pebble layer, a gravel layer, and an anthracite layer, arranged from top to bottom.
[0010] In a further technical solution, the filter media structure includes an upper and lower quartz sand filter layer and an anthracite filter layer.
[0011] In a further technical solution, the anthracite filter layer is filled with anthracite particles with a diameter of 5mm-15mm; the quartz sand filter layer is filled with quartz sand particles with a diameter of less than 2mm.
[0012] In a further technical solution, the filter table is a frame made of fusible plastic, with the filling space arranged vertically through the entire space. A screen with a mesh size of less than 1 mm is laid at the bottom of the filling space.
[0013] In a further technical solution, a floating platform is provided on the side of the main frame, and the controller and water pump are respectively fixedly installed on the platform.
[0014] In a further technical solution, the controller has a waterproof housing, inside which is housed a battery and a PCB control board. The PCB control board is electrically connected to the water pump and the water quality sensor. The PCB control board integrates a Wi-Fi module or a Bluetooth module.
[0015] In a further technical solution, the floating platform is also equipped with photovoltaic panels, which are electrically connected to the PCB control board.
[0016] The advantages of this invention compared to the prior art after adopting the above structure are: 1. The filter media structure at the top of the filter table performs initial physical interception of water, which, combined with the direct absorption of nutrients such as nitrogen and phosphorus by the roots of aquatic plants in the flowerpot and the auxiliary adsorption of ceramsite matrix, forms a dual purification path consisting of physical and biological components, significantly improving the comprehensive removal efficiency of pollutants such as COD, BOD5, ammonia nitrogen, and total phosphorus.
[0017] 2. The filter nozzle has multiple coarse filtration layers, which can perform preliminary filtration of water. The replaceable filter nozzle is easy to maintain.
[0018] 3. The circulating water system uses a water pump to draw surface polluted water to the top of the flowerpot, and then sprays it precisely onto the roots of aquatic plants through filter nozzles. This simulates the leaching effect of natural rainfall, which not only replenishes oxygen to the plant roots, but also prolongs the contact time between the water and the plants and fillers, thereby enhancing the efficiency of microorganisms in decomposing organic matter.
[0019] 4. The filter table and flower pots can be disassembled and replaced individually. When the filter material is clogged or the plants wither, there is no need to remove the entire device. Only the corresponding module needs to be maintained, which greatly reduces the difficulty and cost of operation and maintenance.
[0020] 5. The floating filler frame openings of the main frame also support flexible filling or cleaning to adapt to the needs of rivers with different levels of pollution.
[0021] 6. The water quality sensor integrated into the suction head monitors the concentration of pollutants in the water in real time. The controller automatically starts and stops the water pump according to the preset threshold to avoid unnecessary energy consumption. With the integration of WiFi and Bluetooth modules, the water quality status can be monitored and operating parameters can be adjusted through a mobile APP to achieve intelligent management.
