Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of ecological purification, particularly to a semi-fixed floating pontoon type ditch ecological water purification device. BACKGROUND
[0002] Unreasonable water and fertilizer management can cause excessive nutrients such as nitrogen and phosphorus in farmland production activities, which enter natural water bodies through farmland surface runoff and farmland leakage during precipitation or irrigation, thereby causing persistent agricultural non-point source pollution problems. Excessive nitrogen and phosphorus in farmland runoff can cause rapid reproduction of algae and other plankton, and the content of dissolved oxygen in water decreases, which deteriorates water quality and is an important reason for water eutrophication. At the same time, agricultural non-point source pollution caused by farmland runoff has the characteristics of dispersion, concealment, randomness, etc., and is difficult to monitor, quantify, and control, which is becoming one of the most serious pollution problems in China.
[0003] The ecological ditch is an ecological interception system proposed with the development of ecological water conservancy environment in recent years, and has gradually become a widely used agricultural non-point source pollution process blocking technology. The ecological ditch not only has the drainage and irrigation function of the ditch, but also can intercept and adsorb pollutants in the ditch water, thereby achieving the purpose of purifying water quality, and has good landscape effect. Since aquatic plants have good absorption capacity for nitrogen and phosphorus, the content of nitrogen and phosphorus in water can be greatly reduced by harvesting aquatic plants, and the plants can be recycled by farmers to generate economic benefits, while solving the problem of secondary pollution of plants. However, farmland drainage ditches are generally narrow, and it is not suitable to carry out large-scale destruction and reconstruction of existing hard ditches. Therefore, selecting an economic and reasonable, scientific and efficient way to ecologically transform the existing hard drainage ditch becomes an effective way for ecological purification of farmland runoff.

[0025] Example 1
[0026] like Figures 1-2 As shown, this embodiment provides a semi-fixed floating ditch ecological water purification device, including a fixed pole 1, an ecological floating 2, a buoyancy component 3, and a growth substrate 4. The ecological floating 2 is slidably sleeved on the fixed pole 1. The bottom of the ecological floating 2 is sealed and the top is open. The bottom of the ecological floating 2 is provided with the buoyancy component 3 and the growth substrate 4 is contained inside. The bottom plate of the ecological floating 2 is provided with water-permeable holes. Water-purifying plants are planted on the growth substrate 4. The lower end of the fixed pole 1 is fixed to the bottom of the ditch.
[0027] As an optional solution, in this embodiment, the bottom plate of the ecological pontoon 2 has several water-permeable holes evenly distributed, and each water-permeable hole contains a water-absorbing component. The water-absorbing component can also be a synthetic chemical fiber cotton column.
[0028] As an optional solution, in this embodiment, the water-absorbing component is a water-absorbing cotton thread 5. One end of the water-absorbing cotton thread 5 is fixed in the growth substrate 4, and the other end is located in the water area of the ditch, for absorbing water to nourish the water-purifying plants.
[0029] As an optional solution, in this embodiment, the absorbent cotton thread 5 has a diameter of 2mm-10mm and a length of 10cm-50cm, which is long enough to facilitate water supply to the plant roots when the water volume in the ditch is low.
[0030] As an optional solution, in this embodiment, the diameter of the water-permeable hole is 5mm-10mm, and it can be filled with absorbent cotton thread 5.
[0031] As an optional solution, in this embodiment, the diameter of the fixed pole 1 is 2cm-5cm and the length is 1m-2m. The fixed pole 1 is a smooth metal pole or a rigid plastic pole, which facilitates relative sliding and also facilitates the fixing and guidance of the ecological float 2. The fixed pole 1 can be directly inserted into a hole at the bottom of the ditch for grouting and fixing; alternatively, the bottom of the fixed pole 1 can be cast into a concrete block to utilize the weight of the concrete block for direct fixing.
[0032] As an optional solution, in this embodiment, the buoyancy component 3 is a hollow ring-shaped component, which is adhered to the bottom surface of the ecological pontoon 2. The buoyancy component 3 can be formed by connecting elbows to PVC or PE pipes to create a sealed ring attached to the bottom of the ecological pontoon 2 to provide buoyancy support.
[0033] As an optional solution, in this embodiment, a sliding sleeve 6 is vertically connected to the center of the ecological pontoon 2, which makes it easy to keep the ecological pontoon 2 horizontal and avoid overturning caused by uneven gravity distribution. The fixed pole 1 passes through the sliding sleeve 6, so that the ecological pontoon 2 can float up and down along the fixed pole 1 under the buoyancy of the buoyancy component 3 to adapt to the rise and fall of the water surface in the ditch.
[0034] As an optional solution, in this embodiment, both the buoyancy component 3 and the ecological pontoon 2 are made of polyvinyl chloride (PVC) or polyethylene (PE), which are inexpensive and easy to mold. The size and material of the ecological pontoon 2 and the buoyancy component 3 can be flexibly selected according to actual conditions, making it highly operable.
[0035] As an alternative, in this embodiment, the growth substrate 4 is a lightweight and porous volcanic rock, ceramsite, or biochar particles. Since the buoyancy of the ditch hydraulic and buoyancy components 3 is limited, lightweight and porous materials are preferred as the growth substrate 4.
[0036] As an alternative, in this embodiment, the growth substrate 4 is filled in at least one porous mesh bag with a mesh size of 10-30 mesh, which can reduce the loss of the growth substrate 4 with water and further save costs.
[0037] As an optional option, the water-purifying plants in this embodiment include any one of the following: pothos, iris, pennywort, foxtail grass, reed, duckweed, or water hyacinth. Small water-purifying plants are preferred to avoid being too heavy and overturning the ecological float 2.
[0038] Example 2
[0039] This embodiment provides a semi-fixed float-type ecological water purification device for ditches. The ecological float 2 is made of PVC or PE pipe with a diameter of 40cm-60cm, cut into sections 10cm-20cm high. A PVC or PE circular plate is glued to one end of each pipe section to form a cylinder. A sliding sleeve 6 is then glued to the middle of the cylinder after drilling a hole. The sliding sleeve 6 can also be made from a PVC or PE pipe section with a diameter of 3cm-5cm. The buoyancy component 3 is a sealed ring formed by connecting elbows to PVC or PE pipes and attached to the bottom of the ecological float 2. A fixed support rod 1 is then inserted into the ring. The entire device is inexpensive and durable.
[0040] The semi-fixed floating ditch ecological water purification device of this embodiment has a simple structure, is easy to operate, and is inexpensive. It can automatically float up and down with the water level, without causing ditch blockage, and is easy to replace. It can effectively reduce agricultural non-point source pollution caused by farmland runoff and can achieve ecological water purification function through adsorption by plant roots in narrow ditches.
[0041] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
