Description

Technical Field

[0001] The utility model relates to the technical field of tail mud treatment systems, in particular to a tail mud treatment system for a Chinese sturgeon breeding front water workshop. Background Art

[0002] As an important supporting facility for the reproduction of Chinese sturgeon, the muddy water discharged from the front water workshop mainly includes muddy water discharged from the sedimentation tank, backwash water from the filter tank, and muddy water discharged from the sedimentation tank in the breeding area. At present, a large amount of muddy water generated by the backwash of the horizontal flow sedimentation tank and filter tank in the front water workshop is directly discharged into the municipal pipe network, which puts great pressure on the municipal sewage collection and treatment system. At the same time, as the aquaculture load continues to increase, the concentration of pollutants in the aquaculture tail water increases accordingly. After the aquaculture tail water is directly discharged into the wetland lake, organic matter accumulates at the bottom of the lake, which has a certain degree of negative effect on the water quality of the wetland lake.

[0003] At present, the country attaches increasing importance to environmental protection, and environmental protection standards are becoming more and more stringent. Establishing a treatment system for production sludge in the front water workshop and aquaculture tail water sludge, strengthening the resource utilization of tail sludge, and solving the negative impact of muddy water generated by the front water workshop on the municipal drainage system and wetland lake bottom water quality are of great significance and role in alleviating the contradiction between water use in production and ecological environment, and improving the ecological environment and urban and rural living environment.

[0016] like Figure 1 and Figure 2 As shown, the utility model provides a tail mud disposal system for a water workshop before breeding of Chinese sturgeon, comprising a thickening tank 1, a filter plate 6 vertically slidably arranged in the thickening tank 1, a first row of mud and water pipes 2 and a second row of mud and water pipes 3 connected to the top of the thickening tank 1, a filter press 8 connected to a mud pump 7 at the bottom of the thickening tank 1, and a flocculation tank 9 connected to an overflow pipe at the top of the thickening tank 1; the pipe openings of the first row of mud and water pipes 2 and the second row of mud and water pipes 3 are located below the filter plate 6, and the overflow pipe is located above the filter plate 6.

[0017] The first muddy water pipe 2 transports the muddy water from the breeding area to the concentration tank 1. The muddy water in the sedimentation tank that has been gravity-sedimented is transported to the concentration tank 1 through the second muddy water pipe 3. The first muddy water pipe 2 and the second muddy water pipe 3 both pass through the filter plate 6. The muddy water is transported to the bottom of the filter plate 6. In the process of increasing muddy water, the filter plate is pushed up. The muddy water is initially filtered by the filter plate to produce a certain amount of upper clear liquid. At the same time, the muddy water is gravity-sedimented through the concentration tank 1. Under the pressure of the filter plate 6 and the gravity of the mud in the mud water, the mud water is quickly stratified, and the upper clear liquid at the top overflows into the flocculation tank 9 through the overflow pipe. The upper clear liquid is further purified by the flocculation tank 9, and the remaining mud water is pumped to the filter press 8 through the mud pump 7. The filter press 8 filters the mud water and transports the water separated by the filtration to the flocculation tank 9 for treatment. The produced mud cake is sent out, and the treated water in the flocculation tank 9 is sent to the drainage tank for discharge.

[0018] like Figure 1 As shown, in order to realize the vertical movable installation of the filter plate 6. A mounting seat 4 is fixedly provided in the middle of the relative side wall of the concentrating tank 1, and a guide rod is provided in the middle of the mounting seat 4. The edge of the filter plate 6 is slidably connected to the guide rod, and a spring 5 is mounted on the guide rod, and the bottom end of the spring 5 is connected to the filter plate 6. The top and bottom of the mounting seat 4 are fixedly connected to the side wall of the concentrating tank 1 through a connecting block, and the guide rod in the middle is used for the sliding installation of the filter plate 6; the connecting block at the bottom of the mounting seat 4 is used to support the filter plate 6. After the amount of muddy water in the concentrating tank 1 increases, part of the muddy water cannot pass through the filter plate 6, so that the filter plate 6 moves upward, which will cause the compression of the spring 5, thereby increasing the squeezing of the bottom muddy water by the filter plate 6, and accelerating the stratification of water in the muddy water.

[0019] like Figure 1 The filter plate 6 includes a rectangular frame structure with edges and baffles 13 equidistantly arranged inside the frame structure, and the outer edge of the frame structure fits the inner wall of the concentration tank 1. The frame structure is used to carry the baffles 13, and the equidistantly arranged baffles 13 have a filtering effect.

[0020] like Figure 2 The top width of the baffle rod 13 is greater than the bottom width. By setting the cross-section of the baffle rod 13, the filtering performance of the baffle rod 13 is enhanced, and when the baffle rod 13 is cleaned by the flushing pipe at the top of the concentration tank 1, the sludge blocked between the baffle rods 13 can be easily flushed down.

[0021] like Figure 1 As shown. A feeding pipe 11 for adding flocculants is provided on the top of the flocculation tank 9, and a stirring structure 10 is provided inside the flocculation tank 9. Flocculants are added to the flocculation tank 9 through the feeding pipe 11, and the stirring shaft driven by the motor of the stirring structure 10 drives the stirring rod to stir the muddy water inside the flocculation tank 9, thereby accelerating the mixing of the flocculants and the sludge.

[0022] like Figure 1 As shown. A trough 12 is provided at the bottom of the thickening tank 1, the top surface of the trough 12 is an inclined surface, and the sludge pump 7 is located at the lowest point of the top of the trough 12. By providing the trough 12 with a slope, the sludge is collected on one side of the trough 12, which facilitates the sludge pump 7 to discharge the sludge water in the thickening tank 1.
