Description

Technical Field

[0001] The invention belongs to the technical field of water treatment and relates to a tail water treatment device, in particular to an aquaculture tail water treatment device for controlling agricultural non-point source pollution. Background Art

[0002] Agricultural non-point source pollution mainly comes from the loss of plant nutrients and pesticides in farmland, which will lead to a series of problems such as eutrophication of water bodies, deterioration of water quality, and damage to the ecosystem. Since many lake basins have abundant rainfall, the rainfall process will have a certain impact on the tailwater of farmland. At the same time, the nutrients in the farmland will be discharged with the runoff, which will aggravate the eutrophication process of the water body to a certain extent; during rainfall, a large amount of farmland non-point source pollutants will flow out with the rainfall runoff, causing a certain degree of harm to the surrounding environment. Agricultural tailwater covers a wide area and is dispersed, and affects surface water bodies through various channels. Therefore, the task of governance is arduous and the situation of remediation is complicated.

[0003] After searching, it is found that a Chinese patent document discloses an integrated device for treating farmland wastewater polluted by agricultural non-point source pollution [Application No.: 202311796927.6; Publication No.: CN 117509988 A], which relates to the field of wastewater treatment technology, including a shell, a control box is arranged on the shell, a sedimentation tank is arranged inside the shell, a support plate is symmetrically installed inside the sedimentation tank, a filter plate is fixedly installed on the support plate, and the filter plate is used to separate large impurities carried by sewage, and a strip groove is arranged inside the support plate, and a driving component is arranged inside the strip groove. The present invention facilitates the screening and collection of impurities carried by the wastewater entering the integrated device for treating farmland wastewater polluted by agricultural non-point source pollution by arranging a filter plate and a scraper. The filter plate can screen and filter weeds or other solid wastes carried in the sewage, thereby avoiding the weeds from entering the integrated device for treating wastewater and causing blockage and damage to the wastewater treatment equipment, and at the same time avoiding the occurrence of such phenomena as weeds or solid wastes entering and causing secondary pollution to the water quality.

[0004] Although the wastewater treatment equipment disclosed in this patent avoids the occurrence of secondary pollution of water quality caused by the entry of weeds or solid waste, at present, tail water is generated quickly and in large quantities in large fields. When treating wastewater in this patent, not only is the recycling process cumbersome, but it is also unable to directly recycle wastewater for irrigation of fields. Summary of the invention

[0008] The working principle of the present invention is: the aquaculture tail water of the aquaculture field can be flowed into the tail water ditch through rainfall runoff. When the tail water in the tail water ditch accumulates to a certain extent, multiple silt extraction pumps can be used to extract the tail water in each tail water ditch into the processing frame, and the large particle impurities in the tail water are removed by the filtering component in the processing frame.

When the stirring is uniform, the movement of the stirring frame can be stopped to wait for the precipitation of impurities, nitrogen, phosphorus and other substances in the tail water. When the precipitation is completed, the gaps between the partitions are closed by the closing component, so that the reaction chamber is divided into a precipitation chamber and a clean water chamber, and all the substances precipitated in the tail water are sealed in the precipitation chamber. At this time, the treated water in the clean water chamber can be extracted by the liquid extraction pump, and each aquaculture field is irrigated by the movement of the sprinkler frame to realize the function of tail water recycling.

[0066] The working principle of the present invention is as follows: the tail water of the breeding field 2 flows into the tail water ditch 3 through rainfall runoff. When the tail water in the tail water ditch 3 accumulates to a certain extent, multiple sludge extraction pumps 5 can be used to extract the tail water in each tail water ditch 3 into the filter chamber 19. In the extraction process, the large mass debris in the tail water ditch 3 is separated and filtered through the coarse filter 37, and the extracted tail water sludge is simply filtered to prevent the large mass debris from clogging the pipeline. The tail water accumulated in the filter chamber 19 is extracted into the reaction chamber 9 through the suction pump 20.

The chemical precipitant is injected into the reaction chamber 9 through the drug inlet 38, and the adjusting screw 34 is driven to rotate by the adjusting motor 35. After the adjusting screw 34 rotates, it will drive the sprinkler frame 7 to move, and the sprinkler frame 7 will further drive The stirring frame 13 is moved to stir the tail water in the reaction chamber 9 to assist the chemical precipitant to react. When the stirring is uniform, the movement of the stirring frame 13 can be stopped to wait for the precipitation of impurities, nitrogen, phosphorus and other substances in the tail water. When the precipitation is completed, the servo motor 32 drives the reeling rod 31 to rotate. After the reeling rod 31 rotates, the pull rope 33 is released. After the pull rope 33 is released, the push spring 29 loses the limiting pressure, that is, it pushes the corresponding guide slider 28, so that the two extension plates 30 extend to close the gap between the partitions 10. , so that the reaction chamber 9 is divided into a sedimentation chamber 12 and a clean water chamber 11, and all the substances precipitated in the tail water are sealed in the sedimentation chamber 12.

[0067] In summary, the tail water of the breeding field 2 flows into the tail water ditch 3 through rainfall runoff. When the tail water in the tail water ditch 3 accumulates to a certain extent, multiple silt extraction pumps 5 can be used to extract the tail water in each tail water ditch 3 into the treatment rack 1. The large particles of impurities in the tail water are removed by the filtering components in the treatment rack 1. The tail water after the large particles of impurities are removed enters the reaction chamber 9 for reaction treatment. The tail water reaction process: a chemical precipitant is injected into the reaction chamber 9. At this time, the stirring rack 13 can be moved so that the stirring rack 13 can react the tail water in the reaction chamber 9. Stirring assists the chemical precipitant to react. When the stirring is uniform, the movement of the stirring frame 13 can be stopped to wait for the precipitation of impurities, nitrogen, phosphorus and other substances in the tail water. When the precipitation is completed, the gaps between the partitions 10 are closed by the closing component, so that the reaction chamber 9 is divided into a precipitation chamber 12 and a clean water chamber 11, and all the substances precipitated in the tail water are sealed in the precipitation chamber 12. At this time, the treated water in the clean water chamber 11 can be extracted by the liquid pump 14, and the various breeding fields 2 can be irrigated by moving the sprinkler frame 7 to realize the function of tail water recycling.

[0068] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
