Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device for river pollution sources. Background Technology

[0002] River pollution sources mainly include industrial wastewater, domestic sewage, and agricultural non-point source pollution. Industrial wastewater contains heavy metals, organic matter, and recalcitrant pollutants, requiring targeted treatment. Domestic sewage is mainly composed of organic matter and ammonia nitrogen, which can easily lead to eutrophication of water bodies. Agricultural non-point source pollution is usually caused by pesticide and fertilizer runoff, resulting in excessive nitrogen and phosphorus levels, which is difficult to treat.

[0003] For example, patent number CN206188503U discloses a sewage treatment device for densely distributed sewage outlets in urban and rural waterways, including a purification tank (1) and a filter media area (2) surrounding the purification tank (1). The purification tank (1) is equipped with an aeration device (3). The purification tank (1) is also equipped with at least one sewage outlet (4) and a sewage interceptor (5). The sewage interceptor (5) includes a sewage branch pipe (51) connected to the sewage outlet (4) and a sewage pipe (52) connected to the sewage branch pipe (51). The outlet of the sewage pipe (52) is located inside the purification tank (1). The filter media area (2) is equipped with filter media (21), and a fence (22) is provided on the outside of the filter media (21). Emergent plants (23) are planted on the upper side of the filter media (21). This utility model uses the same sewage outlet treatment device to centrally treat multiple sewage outlets. On the one hand, it efficiently treats the sewage discharged from the sewage outlets. On the other hand, the centralized treatment solves the technical problem of rivers being congested due to the presence of sewage outlet treatment devices everywhere in the prior art.

[0004] However, when existing sewage treatment devices for river pollution sources are in use, larger impurities in the sewage tend to accumulate in the purification tank, affecting the aeration and purification process, and the inspection and maintenance of each structure are relatively difficult.

The lower end of the installation chamber 6 is equipped with a purification tank 9, and the inner side of the purification tank 9 is equipped with an aeration pipe 10. Wastewater is filtered by the filter screen 2 to remove larger impurities, thus achieving preliminary treatment of the wastewater. The drive motor 5 controls the rotation of the spiral blades 3, which pushes the impurities on the surface of the filter screen 2 toward the slag discharge port 4 for discharge. The drive motor 5 can be easily inspected and maintained by removing the inspection door 8. The filter chamber 1 can be removed by unscrewing the bolts on the surface of the mounting plate 7, making it easy to remove the filter chamber 1 from the installation chamber 6. This facilitates the disassembly and replacement of the filter screen 2 and the inspection and maintenance of the internal structure such as the aeration pipe 10.

[0025] Please see Figures 1-4In this embodiment, the upper end of the filter chamber 1 is connected to a drain pipe, and the filter screen 2 and the lower end of the filter chamber 1 are detachably connected by bolts. The filter screen 2 has an arc-shaped structure design. The spiral blades 3 and the upper end of the filter screen 2 are mutually adapted, and the slag discharge port 4 and the right end of the filter screen 2 are mutually adapted. A guide plate is fixedly installed on the outside of the slag discharge port 4. The drive motor 5 is fixedly connected to the left side of the filter chamber 1, and the output end of the drive motor 5 extends to the inside of the filter chamber 1 and is fixedly connected to the left end of the spiral blades 3. Sewage is discharged into the filter chamber 1 from the drain pipe. After being filtered by the filter screen 2, larger impurities are removed, achieving preliminary treatment of the sewage. The drive motor 5 controls the spiral blades 3 to rotate, so that the impurities on the surface of the filter screen 2 are pushed to the slag discharge port 4 for discharge, facilitating the centralized collection and treatment of impurities. The pre-treated sewage is concentrated in the inner side of the purification tank 9 and is supplied with air through the air supply pipe to the aeration pipe 10.

[0027] During operation, wastewater is discharged from the drain pipe into the filter chamber 1. After passing through the filter screen 2, larger impurities are removed, achieving preliminary treatment of the wastewater. The drive motor 5 controls the rotation of the spiral blades 3, pushing the impurities on the surface of the filter screen 2 towards the slag discharge port 4 for discharge, facilitating the centralized collection and treatment of impurities. The pre-treated wastewater is concentrated inside the purification tank 9 and supplied with air through the air supply pipe to the aeration pipe 10. This, combined with the filter media tank 11, performs secondary filtration of the wastewater, achieving purification treatment. During maintenance, the drive motor 5 can be easily inspected and maintained by removing the inspection door 8. The bolts on the surface of the mounting plate 7 can be removed to loosen the fixation of the filter chamber 1, making it easy to remove the filter chamber 1 from the mounting chamber 6. This facilitates the disassembly and replacement of the filter screen 2 and the inspection and maintenance of the internal structures such as the aeration pipe 10.

[0028] Through the above steps, the wastewater is filtered through the filter screen 2 to remove larger impurities, achieving preliminary treatment of the wastewater. The drive motor 5 controls the rotation of the spiral blades 3, causing the impurities on the surface of the filter screen 2 to be pushed towards the slag discharge port 4 for discharge. The inspection door 8 can be removed for easy maintenance of the drive motor 5. The bolts on the surface of the mounting plate 7 can be removed to loosen the fixing of the filter chamber 1, making it easy to remove the filter chamber 1 from the mounting chamber 6. This facilitates the disassembly and replacement of the filter screen 2 and the maintenance of the internal structures such as the aeration pipe 10.
