Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to a spraying device for ammonia and phosphorus removal in wastewater. Background Technology
[0002] With the continuous improvement of national wastewater discharge standards, especially the stringent requirements for ammonia nitrogen and total phosphorus, the simultaneous removal of ammonia nitrogen and total phosphorus is mostly achieved through biochemical processes, particularly for wastewater with low concentrations requiring removal of these pollutants, such as the upgrading of municipal wastewater treatment plants. Various chemicals need to be added during wastewater ammonia and phosphorus removal. Existing methods typically use spraying, but the spraying mechanisms installed around the wastewater tank cannot effectively and evenly spray different areas within the tank, leading to insufficient mixing of wastewater and chemicals and reducing the effectiveness of wastewater treatment. Therefore, we propose a chemical dosing device for wastewater ammonia and phosphorus removal to address these issues.
[0003] A prior art patent, CN216972032U, discloses a solution comprising a mobile vehicle body with a liquid storage tank mounted on its upper end. Support arms are rotatably connected to both sides of the tank, with a connecting sleeve threaded onto one end of each support arm. Three snap-fit pieces are evenly spaced at the lower end of each support arm. Two water pumps are connected to one side of the tank and mounted on the upper end of the mobile vehicle body. One end of each pump is connected to a fixed pipe with a valve installed on it. A spray pipe is threaded onto one end of the fixed pipe, and one spray pipe on the same side is snapped onto the three snap-fit pieces on the same side. Multiple nozzles are evenly spaced at the lower end of the spray pipe. This design allows for adjustment of the spray range based on the width and spacing of the water tank, ensuring stability during spraying. It also facilitates retraction and movement, significantly improving the mixing uniformity of wastewater and treatment agents, thus enhancing treatment efficiency and practicality.
[0004] The shortcomings of existing technology have gradually become apparent with use, mainly in the following aspects:
[0005] First, the existing ammonia and phosphorus removal agent addition equipment is installed directly in the wastewater, which results in the agent addition equipment occupying the internal space of the wastewater tank and affecting the layout and use of other structures in the wastewater tank.
[0006] Secondly, the ammonia and phosphorus removal agent addition equipment is used periodically in sewage tanks, with most of the time spent outside of use. This means that equipping each sewage tank with an ammonia and phosphorus removal agent addition equipment not only involves a large investment, but also the long-term immersion of the ammonia and phosphorus removal agent addition equipment in sewage can easily affect its service life.
[0007] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
[0008] To address the shortcomings of existing technologies, this utility model provides a spraying device for ammonia and phosphorus removal in wastewater.
