Description

Technical Field

[0001] This utility model relates to the field of wastewater filter technology, specifically to a wastewater filter loaded with a new phosphorus removal material. Background Technology

[0002] A wastewater filter is a device used to remove suspended solids and pollutants from water. It utilizes physical or chemical methods to filter out solid particles and impurities from wastewater, thereby improving water quality and meeting discharge standards or reuse requirements. Wastewater filters are essential equipment in industrial, agricultural, and urban wastewater treatment. With increasing environmental awareness, the removal of nutrients from wastewater, such as nitrogen and phosphorus, has become particularly important, especially phosphorus, which is one of the key factors causing eutrophication. Eutrophication not only leads to the proliferation of algae in aquatic bodies, affecting water quality, but also causes serious damage to aquatic ecosystems. Therefore, the development of efficient wastewater phosphorus removal technologies is particularly urgent.

[0003] Utility model patent CN220478247U discloses a wastewater chemical phosphorus removal device, including a base plate. Support legs are fixedly connected to the upper surface of the base plate, and a housing is fixedly connected to the top of the support legs. A circular shell is fixedly connected to the inner wall of the housing, and activated carbon is disposed on the inner wall of the circular shell. A water pump is fixedly connected to the side of the housing, and an outlet pipe is fixedly connected to the outlet end of the water pump. When the water pump operates, it draws the filtered wastewater from the filter box through the inlet pipe and discharges it into the activated carbon through the outlet pipe. The activated carbon adsorbs phosphorus in the wastewater. Then, a water valve is used to open the conduit to discharge the phosphorus-removed wastewater. Afterward, the hook is removed from the hanging rod, and the filter screen is removed from the filter box by hooking the ring with a curved hook. The impurities in the filter box are cleaned and then returned to the filter box, thus achieving the effect of filtering impurities from the wastewater.

[0004] The existing technology described above filters impurities from wastewater through a filter screen in a filter box, and then adsorbs phosphorus from the wastewater through activated carbon in a cylindrical shell. However, relying solely on activated carbon for phosphorus removal is not ideal and cannot meet increasingly stringent emission standards. Therefore, we propose a wastewater filter loaded with a new phosphorus removal material. Utility Model Content

[0005] The purpose of this invention is to provide a wastewater filter loaded with a new phosphorus removal material to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wastewater filter loaded with a new phosphorus removal material includes a buffer tank. The buffer tank, as the core container of the wastewater treatment system, is used to temporarily store wastewater and coordinate the impurity filtration and phosphorus removal processes. The buffer tank contains an impurity removal storage tank and a phosphorus removal storage tank. The impurity removal storage tank stores wastewater after preliminary filtration, providing a pre-treated water source for subsequent phosphorus removal treatment. The phosphorus removal storage tank stores wastewater that meets standards after deep phosphorus removal, facilitating final discharge or reuse. The top of the buffer tank is equipped with an impurity removal filter box connected to the impurity removal storage tank and a phosphorus removal filter box connected to the phosphorus removal storage tank. The impurity removal filter box is used to remove suspended solids and impurities from the wastewater through multi-layer physical filtration, and the phosphorus removal filter box is used to remove phosphorus from the wastewater through chemical adsorption materials.

[0008] The top of the impurity removal filter box is provided with a first inlet pipe for wastewater input. The first inlet pipe is used to introduce the wastewater to be treated into the impurity removal filter box. The impurity removal filter box is detachably connected to three filter boxes arranged vertically and equidistantly. The top of the phosphorus removal filter box is provided with a second inlet pipe. The second inlet pipe is used to transport the pretreated wastewater to the phosphorus removal filter box. The phosphorus removal filter box is detachably connected to two filter boxes arranged vertically. The filter boxes are modular filter units that can be loaded with different filter materials to achieve graded treatment.

[0009] A pump is installed at the top of the buffer tank, located between the impurity removal filter tank and the phosphorus removal filter tank. It is powered by an external power supply and controller. The pump is used to pressurize and transport the wastewater in the impurity removal storage tank to the phosphorus removal filter tank. The input end of the pump is connected to the impurity removal storage tank through a pumping pipe. The pumping pipe is used to connect the impurity removal storage tank and the pump to extract pretreated wastewater. The output end of the pump is connected to the second inlet pipe through a delivery pipe. The delivery pipe is used to transport the wastewater to the second inlet pipe of the phosphorus removal filter tank.

[0010] Preferably, the three filter boxes in the impurity removal filter box are arranged from top to bottom as follows: sand, quartz sand and activated carbon particles. The sand is used to filter large suspended particles, such as silt and leaves, the quartz sand is used to remove fine particles and some dissolved pollutants, and the activated carbon particles are used to adsorb organic matter and initially improve water quality.

[0011] Preferably, the two filter boxes in the phosphorus removal filter box contain sulfur-based denitrification and phosphorus removal filter media and modified clay phosphorus removal agent in sequence from top to bottom. The sulfur-based denitrification and phosphorus removal filter media removes phosphorus and nitrogen pollutants simultaneously through chemical reaction, while the modified clay phosphorus removal agent adsorbs residual phosphorus ions through its high specific surface area, ensuring that the phosphorus concentration in the effluent meets the standards.

[0012] Preferably, the bottom of the inner wall of the filter box is provided with a support net, which is used to support the filter material and prevent it from falling off, while allowing wastewater to pass through. The bottom of the filter box is provided with a liquid guide funnel, which helps to guide the wastewater to the next filter box.

[0013] Preferably, the front side of the impurity removal filter box is hinged with a first door, which is used to open the impurity removal filter box for easy maintenance or replacement of the filter box. The front side of the phosphorus removal filter box is hinged with a second door, which is used to open the phosphorus removal filter box for easy inspection or replacement of the chemical filter media. The rear side of both the first and second doors is provided with rubber pads that abut against the handles. The rubber pads are used to buffer the collision between the handles and the doors and to fix the position of the filter boxes.

[0014] Preferably, the inner wall of the impurity removal filter box is provided with three first U-shaped side plates arranged at equal intervals on both the left and right sides. The filter box inside the impurity removal filter box is located between two first U-shaped side plates arranged opposite each other on the left and right. The first U-shaped side plates are used to support and fix the filter box to ensure that it is placed horizontally and can bear the load stably.

[0015] Preferably, two second U-shaped side plates are provided on both the left and right sides of the inner wall of the phosphorus removal filter box, and the filter box inside the phosphorus removal filter box is located between the two second U-shaped side plates arranged opposite to each other. The second U-shaped side plates are used to fix the phosphorus removal filter box in layers.

[0016] Preferably, the front bottom of the buffer tank is provided with a first drain pipe connected to the impurity removal storage tank and a second drain pipe connected to the phosphorus removal storage tank. Both the first drain pipe and the second drain pipe are provided with control valves. The first drain pipe is used to discharge the residual wastewater in the impurity removal storage tank and the second drain pipe is used to discharge the solution after phosphorus removal treatment.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The wastewater filter loaded with this new phosphorus removal material achieves the step-by-step removal of impurities and phosphorus from wastewater through the synergistic effect of the three-layer physical filtration of the impurity removal filter box and the two-layer chemical adsorption of the phosphorus removal filter box. The sulfur-based filter material simultaneously removes nitrogen and phosphorus, and the modified clay adsorbs residual phosphorus, solving the problem of low phosphorus removal efficiency of traditional activated carbon and meeting emission standards.

[0019] 2. The wastewater filter loaded with this new phosphorus removal material has a detachable filter box structure, which can be quickly disassembled and assembled by means of handles and box doors. Combined with the design of support net and liquid guide hopper, it not only ensures that the filter media is stable and does not leak, but also simplifies the operation process of cleaning and replacing the filter media.
