Description

Technical Field

[0001] This utility model relates to the technical field of denitrification and phosphorus removal devices, and in particular to an integrated device for deep denitrification and phosphorus removal of water. Background Technology

[0002] Nitrogen and phosphorus removal are two important steps in water treatment, mainly used to remove nutrients such as nitrogen and phosphorus from water to prevent eutrophication and protect the aquatic environment. In actual water treatment, nitrogen and phosphorus removal are often carried out in combination to improve the water treatment effect. Many sewage treatment plants use a combination of technologies to ensure that the water quality meets the discharge standards and protect the aquatic ecological environment.

[0003] However, some existing water denitrification and phosphorus removal devices require the addition of reactants to the water during actual use. This usually involves adding the reactants into the reaction tank during the process. However, the mixing of the reactants and water may not be sufficient during the addition process, resulting in insufficient denitrification efficiency and reduced treatment effect. Therefore, it is necessary to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an integrated device for deep nitrogen and phosphorus removal from water.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An integrated device for deep nitrogen and phosphorus removal in water includes a reaction tank. A conical baffle plate is fixedly connected inside the reaction tank. A connecting cylinder is fixedly connected to the top of the reaction tank, and a conveying mechanism is installed inside the connecting cylinder. A stirring mechanism is installed inside the reaction tank.

A phosphorus removal box is installed on the surface of the reaction tank, and a connecting mechanism is provided between the reaction tank and the phosphorus removal box. A support frame is installed at the bottom of the reaction tank. Through the baffle, the reactant inside the storage tank can be evenly distributed into the reaction tank during use, and multiple stirring rods are simultaneously rotated, thereby ensuring more thorough mixing of the water and reactant inside the reaction tank and improving the nitrogen and phosphorus removal effect.

[0007] Preferably, the conveying mechanism includes a baffle, and the bottom of the connecting cylinder has a plurality of first leakage holes, which are evenly distributed in a ring. The baffle is rotatably connected to the center of the bottom of the connecting cylinder. A second leakage hole is formed through the surface of the baffle and cooperates with the plurality of first leakage holes. A guide pipe is fixedly connected to the bottom of the baffle, and the top end of the guide pipe is fixedly connected to the surface of the second leakage hole. The guide pipe is rotatably connected to the top of the leakage plate to restrict the rotation of the baffle, thereby allowing the second leakage hole to communicate with the plurality of first leakage holes, so that the reactant inside the storage tank can be sprayed into the reaction vessel through the guide pipe.

[0008] Furthermore, a rotating shaft is rotatably connected to the center of the reaction vessel. The rotating shaft is vertically arranged, and its bottom end is rotatably connected to the bottom of the reaction vessel.

The output shaft of the motor is fixedly connected to the top of the rotating shaft to drive the rotating shaft to rotate, thereby driving the baffle plate and multiple stirring rods to rotate simultaneously.

[0009] Preferably, the stirring mechanism includes stirring rods, and multiple stirring rods are provided. All stirring rods are fixedly connected to the surface of a rotating shaft. A scraper is rotatably connected to the bottom of the reaction tank. One end of the scraper is fixedly connected to the surface of the rotating shaft. The scraper is located at the bottom of the multiple stirring rods. A drain pipe is fixedly connected to the bottom of the reaction tank. A sealing cap is installed at the bottom end of the drain pipe for stirring the water inside the reaction tank. At the same time, the scraper can scrape off the sediment at the bottom of the reaction tank, so that the sediment can be discharged through the drain pipe.

[0010] Furthermore, a suction pump is installed between the reaction tank and the phosphorus removal box. One end of the first connecting pipe is installed on the surface of the suction pump, and a second connecting pipe is installed on the surface of the suction pump. One end of the second connecting pipe is installed on the surface of the phosphorus removal box. A mounting base is installed at the bottom of the suction pump. Multiple adsorption plates are installed inside the phosphorus removal box, and all of the adsorption plates are vertically arranged. A drain pipe is installed on the side of the phosphorus removal box away from the suction pump for adsorbing phosphorus in the water.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. During use, the baffles allow for the even distribution of the reactant from the storage tank to the reaction vessel, while simultaneously rotating multiple stirring rods to ensure thorough mixing of the water and reactant within the reaction vessel, thereby improving the denitrification and phosphorus removal efficiency.

[0013] 2. Through the arrangement of multiple adsorption plates inside the phosphorus removal box, phosphorus in the water will be adsorbed in multiple stages, thereby improving the water treatment effect. Attached Figure Description
