Description

Technical Field

[0001] The present invention relates to the technical field of filter dams, and in particular to a filter dam body for treating aquaculture wastewater and a use method thereof. Background Art

[0002] During aquaculture, fish and shrimp will produce a large amount of excrement. If the impurities in the aquaculture water are not cleaned and purified regularly, it is easy to affect the health of the fish and shrimp. Directly discharging the aquaculture tail water will easily cause harm to the surrounding environment and pollute the water source in the area. In the existing sewage treatment technology, the aquaculture tail water is generally sent to a sedimentation tank, and the organic residues in the aquaculture tail water are precipitated for a period of time before being sent to a filter tank for filtration. This process is relatively cumbersome.

[0003] However, the cleaning and replacement of existing filter dam nets is a complicated process, requiring divers to dive for a long time to install them. When the water flow is fast and the wind and waves are strong, there are great safety hazards. At the same time, the strength of the nets is not high, and when encountering turbulent water flow, it is easy to cause damage to the filter dam, resulting in irreversible consequences, thereby reducing the utilization efficiency of the filter dam. Summary of the invention

When the water flow is fast and the wind and waves are strong, there are great safety hazards. At the same time, the strength of the net is not strong, and when encountering turbulent water flow, it is easy to cause damage to the filter dam, resulting in irreparable consequences.

[0005] In the first aspect, the present invention provides a dam body for treating aquaculture wastewater. The dam body for treating aquaculture wastewater includes cement piles, a filter dam frame is installed on the upper surface of the cement piles, the filter dam frame is built with two rows of hollow bricks, a block is installed on the bottom surface of the filter dam frame, and three grilles are arranged along the width direction of the cement piles, enclosures are arranged on both sides of the grilles, a hanging ring is fixedly installed on the upper surface of the grilles, a blocking net is arranged on one side surface of the filter dam frame, and a back side of the blocking net is arranged.

[0006] The barrier net includes a positioning component installed on the surface of one end of the enclosure plate, and the interior of the positioning component is movably connected with a mounting component.

[0007] The invention comprises a buffer component arranged on the left side surface of the filter dam frame, and a protective component is fixedly installed on the surface of the buffer component.

[0008] In some embodiments, the grille is made of fiberglass with a thickness of 50 mm and an aperture of 38*38 mm. The spacing between each grille is 0.4 m.

[0009] In some embodiments, the spacing between each grid is filled with four filter materials, which are pebbles, expanded clay, zeolite and gravel. The filter materials are distributed vertically, and a stainless steel mesh box is used for loading and unloading the filter materials. The size of the mesh box is 1.5*0.38, and ear hooks are provided on both sides of the mesh box for easy loading and unloading.

[0010] In some embodiments, the positioning assembly includes a positioning frame fixedly mounted on one side of the enclosure, an adjusting screw is rotatably connected to the interior of the positioning frame, a positioning clamp is rotatably mounted on one end of the adjusting screw, a positioning rod is fitted on the inner surface of the positioning clamp, and a mounting groove is mounted on the surface of the positioning rod.

[0011] In some embodiments, the mounting assembly includes a limit rod threadedly connected to the inside of the mounting slot, the limit rod has a clamping strip clamped inside, a limit hole is provided inside the clamping strip, and one side surface of the clamping strip is fixedly connected to one side surface of the blocking net.

[0012] In some embodiments, the buffer assembly includes a buffer sleeve located on the left side surface of the filter dam frame, a buffer is fixedly installed on the surface of the buffer sleeve, a telescopic rod is movably connected inside the buffer, and a positioning plate is fixedly installed at one end of the buffer sleeve.

[0013] In some embodiments, the protective assembly includes a support tube fixedly mounted on one side surface of the positioning plate, a support rod fixedly connected to one side surface of the support tube, a protective plate fixedly mounted on one end of the support rod, and the protective plate is located on the left side surface of the filter dam frame.

[0014] In a second aspect, the present invention further provides a method for using a filter dam body for treating aquaculture wastewater, characterized in that it comprises the following steps:

[0015] Step 1: Use cement piles as fixed supports, and use two rows of hollow bricks on their surface to build the external structure to form a filter dam frame, and the direction of the hollow bricks should be consistent with the direction of water flow.

[0016] Step 2: A fine mesh barrier should be set up in front of the dam, with its height level with the filter dam frame, to intercept floating objects such as fallen leaves.

[0017] Step 3: Set three fiberglass grilles in the middle of the filter dam along the width direction. The grilles are 50mm thick and 38*38mm in diameter. The spacing between each block is 0.4m.

[0018] Step 4. Select four kinds of filter media, namely pebbles, expanded clay, zeolite and crushed stone, according to the direction of water flow in the dam body. Divide the filter media particles into four categories from large to small and distribute them vertically into four layers. Fill the gaps to allow the tail water after natural river sedimentation to pass through. When filtering the dam, stainless steel mesh boxes are used for loading and unloading of fillers. The mesh boxes have a size of 1.5*0.38 and ear hooks on both sides for easy loading and unloading. Consider flushing the fillers regularly.

[0019] Compared with the prior art, the advantages and positive effects of the present invention are:

[0020] 1. The present invention changes the construction form of the filter dam, adopts a simple cement pile as a fixed support, and uses a stainless steel filter screen and a mesh box as a filter material enclosure structure. This method is applied to the filling of biological ceramsite filter materials. Through further decomposition, adsorption and filtration, the use effect is the same as that of the brick-concrete structure filter dam, but it is simple in construction, operation and maintenance, and reduces construction costs, and has a very good demonstration significance.

[0021] 2. The present invention changes the method of random loading of multiple filter materials or horizontal layered loading of multiple filter materials inside the filter dam. This scheme selects four filter materials, namely pebbles, expanded clay, zeolite and crushed stone, according to the direction of water flow, and divides the filter material particles into four categories from large to small and vertically distributes them into four layers. The middle layer is a zeolite layer and a calcium-containing expanded clay layer that have better effects in removing ammonia nitrogen, phosphorus and other substances in the water body. When the tail water after natural river sedimentation passes through the filter dam, the larger suspended particles are removed first, and then the ammonia nitrogen, phosphorus and other substances are removed through the slow decomposition of the effective substances of expanded clay and zeolite. Finally, the crushed stone is further filtered to remove tiny particles, so that the filter dam not only has an effective filtering function, but also has the decomposition and adsorption functions of organic matter.

In order to more clearly understand the technical means of the present invention, it can be implemented in accordance with the contents of the specification.

At the same time, three grids 5 made of fiberglass are set in the middle of the filter dam along the width direction, and four kinds of filter materials, pebbles, ceramsite, zeolite, and crushed stone, are filled in each spacing to filter wastewater. The filter material particles are divided into four categories from large to small and vertically distributed into four layers, and the middle layer is a zeolite layer and a calcium-containing ceramsite layer with better effects in removing ammonia nitrogen, phosphorus and other substances in the water body, so that the tail water after sedimentation in the natural river channel can be filtered.
