Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and specifically relates to a wastewater treatment adsorption tank. Background Technology

[0002] Adsorption tanks, a common piece of equipment in wastewater treatment, are widely used in the purification of various wastewaters, including industrial wastewater and domestic sewage. They primarily utilize adsorption materials (such as activated carbon, resin, and zeolite) to adsorb pollutants in the water, thereby purifying the water and removing harmful substances. In recent years, with increasingly stringent environmental protection requirements and the continuous development of wastewater treatment technologies, adsorption has become one of the most widely used water treatment technologies due to its simple operation, low cost, and significant treatment effect.

[0003] Currently, the working principle of wastewater treatment adsorption tanks relies on the fact that when water flows through a tank filled with adsorbent material, pollutants come into contact with the adsorbent and undergo an adsorption reaction. Chinese Patent Publication No. CN222809335U (Application No. CN202422001123.9) discloses a wastewater treatment tank that can filter and adsorb wastewater. However, in practical applications, adsorption tanks often face some technical problems, especially the direction of water flow and the issue of impurity sedimentation. Maintaining a vertical flow direction combined with overflow can lead to insufficient sedimentation of wastewater or cause fluctuations in the sediment at the bottom, thereby reducing the primary treatment efficiency, especially in large-scale treatment, and thus affecting the overall treatment effect of the adsorption tank. Utility Model Content

[0004] In view of this, the present invention provides a wastewater treatment adsorption tank that can solve the problem of insufficient sedimentation and uneven bottom sedimentation, which leads to a decrease in the primary treatment efficiency of wastewater.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a wastewater treatment adsorption tank, including a treatment tank body. The treatment tank body is provided with a first treatment chamber and a second treatment chamber, which are connected by a connecting channel. The first treatment chamber and the second treatment chamber are detachably connected with filter plates and adsorption plates. The first treatment chamber includes a filtration section and a sedimentation section. A sedimentation baffle is provided above the sedimentation section, and a sewage discharge trough is provided below the sedimentation section. The sedimentation baffle includes a central protrusion and a smooth outer periphery. A channel is opened at the bottom of the sewage discharge trough, and a valve is provided inside the outlet channel.

[0007] The technical effects of the wastewater treatment adsorption tank provided by this utility model are as follows: By setting up a first treatment chamber and a second treatment chamber and connecting them through a connecting channel, the wastewater treatment process can be effectively divided into multiple treatment stages; the filtration section and sedimentation section in the first treatment chamber allow the wastewater to undergo coarse filtration first to remove large particulate impurities, and then solid particles are settled through the sedimentation section, further improving the purification effect of the wastewater; the sewage discharge tank at the bottom of the sedimentation section is conducive to the accumulation of sediment and facilitates discharge, thereby improving the treatment efficiency; by setting a sedimentation baffle above the sedimentation section inside the first treatment chamber, the water flow is prevented from impacting the sedimentation effect; the sedimented impurities can be discharged through the bottom channel, and the valve is used to control the opening and closing of the bottom channel.

[0008] Based on the above technical solution, the wastewater treatment adsorption tank of this utility model can be further improved as follows:

[0009] An inclined overflow baffle is installed between the first and second processing chambers, and a connecting channel is located above the overflow baffle. A drainage pump is installed at the bottom of the second processing chamber, and the output end of the drainage pump is connected to the drainage channel.

[0010] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: An inclined overflow baffle is installed between the first treatment chamber and the second treatment chamber, and a connecting channel is opened above the overflow baffle; this allows wastewater to flow smoothly into the second treatment chamber after sedimentation treatment in the first treatment chamber. At the same time, the overflow baffle controls the flow rate of the wastewater, avoiding poor sedimentation treatment caused by excessively fast wastewater flow; the inclination angle of the overflow baffle effectively controls the overflow volume and flow rate, thereby maintaining good wastewater flow and preventing the water from directly entering the second treatment chamber through the connecting channel; it also guides the sediment particles to fall into the bottom sludge tank, playing a guiding role.

[0011] Furthermore, the filter plate includes a first filter plate and a second filter plate, with the first filter plate being detachably connected to the inner wall of the filter section.

[0012] Furthermore, the filter screen holes on the first filter plate are located on the side away from the connecting channel.

[0013] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by designing the filter screen holes of the first filter plate on the side away from the connecting channel, the wastewater flow path is optimized, so that the wastewater is first coarsely filtered in the first treatment chamber, reducing the impact of particulate matter on the subsequent treatment section, which helps to improve the overall efficiency of wastewater treatment.

[0014] Furthermore, the sedimentation baffle is detachably connected to the inner wall of the sedimentation section through the outer peripheral smooth part, and elliptical through holes are opened on both the outer periphery of the central protrusion and the outer peripheral smooth part.

[0015] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the sedimentation baffle prevents the wastewater from flowing too rapidly, thus affecting the sedimentation of impurities at the bottom; the elliptical through holes on the central protrusion and the outer peripheral flat part allow the wastewater to flow through, improving the sedimentation efficiency.

[0016] Furthermore, the adsorption plate includes an activated carbon layer and an alumina layer, with the activated carbon layer being the upper layer and the alumina layer being the lower layer.

[0017] The beneficial effects of adopting the above-mentioned improved scheme are: organic pollutants are adsorbed by the activated carbon layer and inorganic pollutants are adsorbed by the alumina layer, thereby enhancing the adsorption and treatment capacity for different types of pollutants.

[0018] Furthermore, the adsorption plate and the second filter plate are detachably connected to the inner wall of the second treatment chamber via an outer liner.

[0019] The beneficial effects of adopting the above-mentioned improvement scheme are: the outer liner can provide support for the second filter plate and the adsorption plate, while also enabling disassembly and installation, facilitating maintenance, replacement and cleaning.

[0020] Furthermore, a set of circular through holes is provided at the center of the central protrusion.

[0021] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the circular through-hole design of the central protrusion can optimize the flow path of wastewater, allowing the wastewater to pass through the sedimentation baffle more evenly, thereby improving the sedimentation effect. The circular through-hole also helps to reduce flow resistance and prevent the wastewater from flowing too rapidly.

[0022] Furthermore, the overflow baffle has an inclination angle of 30° to 55°.

[0023] The beneficial effects of adopting the above-mentioned improvement scheme are: by setting the angle, excessive overflow or excessive flow rate is prevented, the flow state of wastewater is effectively controlled, and the treatment effect is optimized.

[0024] Furthermore, a sealing cover is installed at the top of the treatment tank, and a connection port is provided at the top of the sealing cover on the side closest to the first treatment chamber.

[0025] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the sealing cover effectively seals the tank to prevent external impurities from entering, while providing a connection port to facilitate connection with external equipment, thereby enhancing the stability and ease of operation of wastewater treatment.

[0026] Compared with existing technologies, the beneficial effects of the wastewater treatment adsorption tank provided by this utility model are as follows: By setting a sedimentation baffle above the sedimentation section, the solid matter in the wastewater is effectively stabilized and settled, reducing the burden on subsequent treatment. At the same time, the design of the sewage discharge tank and sewage discharge channel facilitates the cleaning of sediments in the wastewater, thereby improving treatment efficiency. The first treatment chamber and the second treatment chamber are isolated by an inclined overflow baffle. The overflow baffle allows the wastewater to form a certain flow velocity and direction when passing through, which helps to optimize the flow path of the wastewater, avoid uneven distribution of water flow, and ensure that the wastewater is fully contacted and treated in each treatment area. In terms of adsorption and filtration, the adsorption plate structure of activated carbon layer and alumina layer can effectively adsorb harmful substances in wastewater. Overall, through multiple treatment methods such as layered filtration, sedimentation, and adsorption, the wastewater treatment efficiency is improved, while facilitating subsequent maintenance.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0033] like Figure 1Figure 2 shows an embodiment of a wastewater treatment adsorption tank provided by this utility model. In this embodiment, it includes a treatment tank body 10, and a first treatment chamber 11 and a second treatment chamber 12 are provided inside the treatment tank body 10. The first treatment chamber 11 and the second treatment chamber 12 are connected by a connecting channel 13. Filter plates and adsorption plates are detachably connected inside the first treatment chamber 11 and the second treatment chamber 12. The first treatment chamber 11 includes a filter section 111 and a sedimentation section 112. A sedimentation baffle 14 is provided above the sedimentation section 112, and a sewage discharge trough 15 is provided below the sedimentation section 112. The sedimentation baffle 14 includes a central protrusion 141 and an outer peripheral smooth section 142. A channel is opened at the bottom of the sewage discharge trough 15, and a valve 16 is provided inside the outlet channel.

[0034] In operation, wastewater is first introduced into the treatment tank through the connection port and enters the first treatment chamber. The wastewater first passes through the filtration section, where the filter screen of the first filter plate removes large particulate pollutants. After preliminary filtration, the wastewater flows into the sedimentation section, where the central protrusion and the outer flat area of ​​the sedimentation baffle form an effective buffer sedimentation zone, allowing solid impurities to settle. The sludge discharge trough below the sedimentation section is connected to the outside via a channel, allowing the deposited impurities in the wastewater to be discharged. Simultaneously with the sedimentation, the upper layer of water flows through the overflow baffle and connecting channel into the second treatment chamber. There, it is further treated by the second filter plate and adsorption plate (composed of activated carbon and alumina layers). The activated carbon layer adsorbs organic pollutants, while the alumina layer adsorbs metal ions and other inorganic pollutants. The treated wastewater is then discharged through the drainage channel by a drainage pump.

[0035] In the above technical solution, an inclined overflow baffle 17 is provided between the first processing chamber 11 and the second processing chamber 12, and a connecting channel 13 is provided above the overflow baffle 17. A drainage pump is provided at the bottom of the second processing chamber 12, and the output end of the drainage pump is connected to the drainage channel.

[0036] Furthermore, in the above technical solution, the filter plate includes a first filter plate 1111 and a second filter plate 121, and the first filter plate 1111 is detachably connected to the inner wall of the filter section 111.

[0037] Furthermore, in the above technical solution, the filter mesh holes on the first filter plate 1111 are located on the side away from the connecting channel 13.

[0038] Furthermore, in the above technical solution, the sedimentation baffle 14 is detachably connected to the inner wall of the sedimentation section 112 through the outer peripheral smooth part 142, and elliptical through holes are provided on both the outer periphery of the central protrusion 141 and the outer peripheral smooth part 142.

[0039] Furthermore, in the above technical solution, the adsorption plate includes an activated carbon layer 1211 and an alumina layer 1212, with the activated carbon layer 1211 being the upper layer and the alumina layer 1212 being the lower layer.

[0040] Furthermore, in the above technical solution, the adsorption plate and the second filter plate 121 are detachably connected to the inner wall of the second treatment chamber 12 via the outer liner 18.

[0041] Furthermore, in the above technical solution, a set of circular through holes is provided at the center of the central protrusion 141.

[0042] Furthermore, in the above technical solution, the tilt angle of the overflow baffle 17 is 30°~55°.

[0043] Furthermore, in the above technical solution, a sealing cover 101 is installed at the top of the treatment tank 10, and a connection port is provided at the top of the sealing cover 101 on the side near the first treatment chamber 11.

[0044] Specifically, the principle of this invention is as follows: By adding a sedimentation section and a filtration section to the first treatment chamber, and utilizing the central protrusion and the smooth outer periphery of the sedimentation baffle, the wastewater sedimentation efficiency is effectively improved. By setting channels and valves at the bottom of the discharge tank, the discharge of impurities can be more precisely controlled, ensuring efficient wastewater discharge and treatment. Furthermore, the overflow baffle's tilt angle is set between 30° and 55°, optimizing the wastewater flow rate and direction, ensuring a smooth transition between the two treatment chambers while guaranteeing sufficient sedimentation. The adsorption plate, by combining activated carbon and alumina layers, significantly improves the adsorption efficiency of harmful substances in the wastewater. The upper layer of activated carbon helps to adsorb large particulate pollutants more quickly, while the alumina layer effectively removes dissolved substances from the water. Through multi-stage filtration, sedimentation, and adsorption, wastewater is effectively purified, making it suitable for treating various types of industrial wastewater.
