Abstract
Description
Technical Field
[0001] This utility model relates to the field of ditch technology, and in particular to an ecological ditch. Background Technology
[0002] Ecological ditches are a type of farmland drainage ditch. Through ecological structural modification and adjustment, and optimization of ecological service functions, they have a certain purification effect on non-point source pollution entering with surface runoff and farmland runoff, preventing large amounts of non-point source pollution from being directly discharged into nearby rivers and lakes. Ecological ditches also play a role in degradation and transport; after initial degradation, the water flows into wetlands or other end-of-pipe treatment facilities or into rivers and lakes.
[0003] Existing technologies primarily involve designing ecosystems at the bottom and slopes of ditches. Slopes mainly utilize ecological revetments with vegetation, while the ditches themselves are designed with a combination of seepage prevention, filler materials, and vegetation. The aim is to degrade pollutants through the ecosystem of filler materials, plants, and microorganisms as water flows into and through the ecological ditches. The design process focuses primarily on the selection of degrading plants and filler materials, specifically choosing combinations with relatively high treatment efficiency for ammonia nitrogen, total nitrogen, and total phosphorus based on the pollution characteristics of agricultural non-point source wastewater.
[0004] Common ecological ditches usually have the following common problems: (1) Surface runoff brings a large amount of farmland garbage into the ditches, mainly crop straw, agricultural film, pesticide and fertilizer packaging, etc., causing blockage and more serious pollution; (2) Surface runoff brings a lot of soil. Since most current ecological ditches focus on the purification function of the ditches, various plants are planted at the bottom of the ditches and various fillers such as pebbles and zeolite are laid. In fact, it will be very difficult to clean the bottom of the ditches, and the silt is difficult to clean. In addition, the withering and decay of plants will make it difficult to play the role of the ditches; (3) Newly built ecological ditches are mostly straight ditches with fast water flow. The residence time in the ditches is too short, and the nitrogen and phosphorus degradation efficiency is low; (4) After the ditches collect the runoff, it will eventually be treated in a unified manner in wetlands or other end-of-pipe treatment facilities, which will cause greater pressure on the degradation of end-of-pipe pollutants. This will require higher treatment facilities and a larger area. Therefore, we propose an ecological ditch. Utility Model Content
[0005] This utility model addresses the shortcomings of existing technologies by providing an ecological ditch. By adding a silt collection device to the ditch bank, the amount of agricultural waste and silt entering the ecological ditch is reduced, thus lowering the difficulty of subsequent cleaning.

[0028] Example 1:
[0029] Please see Figure 1 and Figure 2 An ecological ditch includes a sloping slope 1 and a ditch body 2. The sloping slope 1 is installed in pairs on both sides of the ditch body 2. The slope is designed to facilitate the introduction of water into the lake. The ditch body also includes: ecological wooden piles 3 fixed at the toe of the sloping slope 1, which can buffer the water flow and prevent mudslides. One side of the ecological wooden pile 3 is abutted against a soil collection device 4, which can intercept the soil washed into the ditch and facilitate the removal of the collected soil. The bottom of the soil collection device 4 is provided with a sliding component 5, which can facilitate the movement of the soil collection device 4 to the bank for treatment. The ditch body 2 also includes a filler layer 7 fixed at the bottom of the ditch body 2 to enhance the ditch's purification capacity.
[0030] Furthermore, such as Figure 3 and Figure 4 As shown, the soil collection device 4 includes a silt collection bucket 8 and a net bag 9. One side of the silt collection bucket 8 abuts against the ecological wooden stake 3. The silt collection bucket 8 is provided with a placement groove, and the net bag 9 is fixed in the placement groove. Water flows into the silt collection bucket 8, and the silt is collected by the silt collection bucket 8, which facilitates the interception of soil washed into the ditch and makes it easy to clean up the collected soil. The net bag 9 is designed to collect production waste such as straw washed into the ditch. The opening of the net bag 9 can be retracted for easy packing and binding.
[0031] Furthermore, such as Figure 1 As shown, a small ecological pond 13 is set up at intervals in the ditch body 2. The small ecological pond 13 is constructed using natural pits, ponds or depressions to further purify non-point source water such as farmland runoff. The ecological pond is a biological treatment facility that uses natural purification capabilities to treat low-pollution water. Its sewage purification process is similar to the self-purification process of natural water bodies. It is equipped with dikes and seepage prevention layers. Aquatic plants are planted in the pond, and native aquatic animals such as fish, crabs, shellfish and snails are released to enhance aquatic biodiversity and form a benign cycle of water ecological self-purification system.
[0032] Furthermore, such as Figure 1 and Figure 5As shown, the filler layer 7 includes an HDPE geotextile layer 14, a zeolite layer 15 on top of the HDPE geotextile layer 14, a planting soil layer 16 on top of the zeolite layer 15, and a grass cover layer 17 on top of the planting soil layer 16. The filler layer 7, which is a combination of HDPE geotextile layer 14, zeolite layer 15, planting soil layer 16, and grass cover layer 17, is designed to degrade pollutants through the ecosystem of filler, plants, microorganisms, and other components during the process of water flowing into and through the ecological ditch.
[0033] Furthermore, such as Figure 1 As shown, the upper surface of the sloping slope 1 is paved with precast concrete triangular bricks, and short grass is sown in the openings of these precast concrete triangular bricks, making the paving relatively convenient.
[0034] Example 2:
[0035] Based on Example 1, according to Figure 3 and Figure 4 As shown, it is worth noting that the sliding assembly 5 includes two pairs of pulley groups 10 installed at the bottom of the sludge collection bucket 8. Multiple tracks 11 are evenly distributed on the slope surface of the inclined slope 1. The pulley groups 10 are slidably connected in the tracks 11. The pulley groups 10 slide in the tracks 11, thereby making the sludge collection bucket 8 more stable and reliable when pulled.
[0036] The upper side of the silt collection bucket 8 is fixed with a hook 12, and a rope 6 is fixed to the hook 12. The end of the rope 6 away from the hook 12 is tied to the bank of the sloping slope 1 through a wooden stake. The end of the rope 6 pulls the hook 12 to move, which in turn causes the hook 12 to slide the silt collection bucket 8 on the sloping slope 1 until the silt collection bucket 8 moves to the bank position. At this time, personnel can replace the silt collection bucket 8 and remove the net bag 9.
[0037] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
