Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a device for treating acetylmethylamine phosphorus-containing wastewater. Background Technology

[0002] Phosphate-containing wastewater typically refers to wastewater containing organic phosphorus generated during the production of acephate. The organic phosphorus in this type of wastewater usually needs to be converted into inorganic phosphorus through biological, chemical, or physical treatment before it can be removed. Biochemical methods primarily utilize the growth and metabolism of microorganisms to decompose organic phosphorus-containing substances, thereby releasing inorganic phosphorus. Chemical methods mainly use oxidants such as sodium hypochlorite to oxidize and decompose organic phosphorus-containing substances, releasing inorganic phosphorus. Physical methods mainly remove organic phosphorus-containing substances directly from the wastewater through coagulation, adsorption, and other methods.

[0003] Currently, there is a lack of specialized water treatment devices for phosphorus removal from acephate organophosphorus wastewater on the market. Most treatment devices are non-specific and have a certain conversion efficiency of organophosphorus, resulting in low efficiency of converting organophosphorus to inorganic phosphorus and weak device specificity. To achieve the desired treatment effect, multiple multi-functional unit devices need to be combined or used in multiple stages, which leads to problems such as excessive overall land area and high investment costs. Furthermore, the hydraulic transfer between multiple devices increases the energy consumption of the system.

[0004] In addition, when existing multi-device, multi-process, and multi-unit combinations are used to treat phosphorus-containing wastewater containing acephate, the lack of coordination among the units makes it difficult to achieve the goal of comprehensive reagent saving and comprehensive energy saving. This independent treatment mode results in low actual phosphorus removal efficiency. In order to achieve the target phosphorus removal effect, the only way is to increase the amount of reagent added or extend the hydraulic retention time, which in turn increases the system operating cost. Utility Model Content

[0005] The purpose of this invention is to provide a treatment device for acetamiprid phosphorus-containing wastewater, which can be used in a single reactor to efficiently convert organic phosphorus in acetamiprid phosphorus-containing wastewater, achieving an organic phosphorus conversion efficiency of over 99% and effectively removing phosphorus from the acetamiprid phosphorus-containing wastewater.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an acetylamine phosphorus-containing wastewater treatment device, comprising a tower body, wherein a wastewater distributor, an internal electrolytic packing, and a hydrogen peroxide distributor are provided inside the tower body, the internal electrolytic packing is located below the wastewater distributor, the hydrogen peroxide distributor is located below the internal electrolytic packing, and an inlet and an outlet are provided on the side of the tower body, the inlet being connected to the wastewater distributor.

[0007] By adopting the above technical solution, wastewater enters the distributor through the inlet on the tower body and is evenly distributed onto the internal electrolytic packing. The internal electrolytic packing, made of iron and carbon sintered material, forms countless tiny galvanic cells in the wastewater environment. Through the action of microcurrent, the chemical bonds of large-molecule phosphorus-containing substances in the wastewater are broken, converting them into small-molecule organic phosphorus. In addition, the internal electrolytic packing is made of iron and carbon sintered material. Iron, as the anode, easily loses electrons and releases ferrous ions. As the wastewater continues to flow downwards into the oxidation zone, the ferrous ions in the packing meet the hydrogen peroxide introduced by the hydrogen peroxide distributor below. Under acidic conditions, a Fenton reaction occurs, where the ferrous ions act as a catalyst and are converted into ferric ions. At the same time, the Fenton reaction converts small-molecule organic phosphorus into inorganic phosphorus (phosphate). The ferric ions combine with the phosphate to produce ferric phosphate precipitate, thereby removing phosphorus from the acetamiprid phosphorus-containing wastewater.

[0008] The internal electrolysis packing is made of iron and carbon sintered together. The iron and carbon are sintered at high temperature to form a porous and rigid integral structure. The micropores can increase the specific surface area, improve the reaction contact efficiency, and allow wastewater to flow smoothly to ensure the internal electrolysis reaction is complete. In addition, the rigid integral structure can improve the stability of the packing.

[0009] A further feature of this invention is that the wastewater distributor is a sawtooth annular weir-type distributor, which includes a guide ring and an annular flow channel. The guide ring is concentrically arranged with the tower body, the top of the guide ring is sawtooth-shaped, and an annular flow channel is provided between the guide ring and the tower body. The annular flow channel is connected to the inlet.

[0010] By adopting the above technical solution, after the wastewater is injected into the annular flow channel from the inlet, a circumferentially uniform annular water flow is formed in the closed loop space. When the water level overflows the top of the sawtooth guide ring, the water flow overflows downward due to gravity. The sawtooth structure of the guide ring cuts the annular water flow into multiple independent water streams. Each sawtooth notch is equivalent to a miniature water distribution port, so that the water flow impacts the surface of the internal electrolysis packing in a dispersed form, ensuring that the packing and wastewater are in full contact and improving the efficiency of the internal electrolysis reaction.

[0011] A further feature of this invention is that the hydrogen peroxide distributor is a perforated pipe distributor.

[0012] By adopting the above technical solution, the perforated pipe water distributor is usually composed of a main pipe and an upward branch pipe. Many small holes with equal spacing and equal diameter are evenly arranged on the upper side of the branch pipe. Hydrogen peroxide flows from the main pipe into the branch pipe and then flows out through the holes of the branch pipe, thereby achieving the function of uniform water distribution.

[0013] Countercurrent mixing of hydrogen peroxide and wastewater can enhance their contact through reverse flow, prolonging the reaction time, increasing the mass transfer area, reducing reagent waste and pollutant residue, and efficiently improving the degradation of organic matter.

[0014] A further feature of this invention is that a hydrogen peroxide inlet is provided on the side of the tower body, and the hydrogen peroxide inlet is connected to the hydrogen peroxide distributor.

[0015] By adopting the above technical solution, hydrogen peroxide is injected through the hydrogen peroxide inlet on the side of the tower body and then enters the hydrogen peroxide distributor inside the tower body.

[0016] A further feature of this invention is that a sieve plate is provided between the internal electrolytic packing and the hydrogen peroxide distributor, and the sieve plate supports the internal electrolytic packing.

[0017] By adopting the above technical solution, the sieve plate firmly supports the internal electrolytic packing material made of iron-carbon sintering, bearing its weight and maintaining the stability of the packing structure, preventing the reaction effect from being affected by the deformation of the packing material due to accumulation; on the other hand, through the appropriate pore size design, the wastewater to be treated can pass smoothly through the packing layer, ensuring uniform flow of the reaction medium, avoiding blockage and air resistance, ensuring full contact between the packing material and the reaction medium, and improving the efficiency of the internal electrolytic reaction.

[0018] A further feature of this invention is that: a gas distribution head is provided inside the tower body, and a gas distributor is provided outside the tower body; the gas distribution head is connected to the gas distributor; the gas distribution head is located below the hydrogen peroxide distributor; the gas distribution head distributes gas upwards; and air source ozone is introduced into the gas distributor.

[0019] A further feature of this invention is that the air distributor is a nanobubble generator.

[0020] By adopting the above technical solution, air-source ozone enters the nanobubble generator and then enters the gas distribution head to form nanobubbles. In the lower part of the oxidation zone, the ozone reacts with the untreated organic phosphorus-containing substances from the Fenton reaction to convert them into inorganic phosphorus, thereby achieving deep oxidation and transformation of organic phosphorus substances and improving treatment efficiency.

[0021] Nanobubbles have a large specific surface area, increasing contact sites and shortening diffusion distance to accelerate mass transfer; they are also highly stable and uniformly distributed, avoiding uneven reaction areas and improving the efficiency and thoroughness of organophosphorus removal.

[0022] The residual air after the ozone is depleted, mainly nitrogen with trace amounts of ozone and oxygen, will continue to rise in the device, causing disturbance and agitation in the internal electrolysis section and Fenton section, effectively preventing the internal electrolysis packing from caking and achieving wastewater homogenization.

[0023] A further feature of this invention is that a mud-water separator is also provided inside the tower body, and the mud-water separator is located below the gas distributor.

[0024] A further feature of this invention is that the mud-water separator is a sedimentation-type mud-water separator with a funnel-shaped cavity structure, the water outlet is located on one side of the mud-water separator, and a mud discharge port is provided at the bottom of the tower body.

[0025] By adopting the above technical solution, the mud-water separator below the aerator separates phosphate sludge from water through sedimentation. The outlet and sludge discharge outlet achieve water and sludge treatment. The funnel-shaped inclined inner wall can guide the flow of the mud-water mixture, slow down the liquid flow rate, and provide sufficient settling time for suspended sludge particles. The conical bottom forms a contraction space that can naturally collect the settled sludge, reduce sludge residue in the cavity, facilitate subsequent centralized discharge, improve sludge collection efficiency, and the device has high overall treatment efficiency and strong continuity, reducing the energy consumption cost of multiple hydraulic transfers.

[0026] The beneficial effects of this utility model are:

[0027] 1. Wastewater enters the distributor through the inlet on the tower body and is evenly distributed onto the internal electrolytic packing. The internal electrolytic packing, made of iron and carbon sintered material, forms countless tiny galvanic cells in the wastewater environment. Through the action of micro-current, the chemical bonds of large-molecule phosphorus-containing substances in the wastewater are broken, converting them into small-molecule organic phosphorus. In addition, the internal electrolytic packing is made of iron and carbon sintered material. Iron, as the anode, easily loses electrons and releases ferrous ions. As the wastewater continues to flow downwards into the oxidation zone, the ferrous ions in the packing meet the hydrogen peroxide introduced by the hydrogen peroxide distributor below. Under acidic conditions, the Fenton reaction occurs, with the ferrous ions acting as a catalyst and converting into ferric ions. At the same time, the Fenton reaction converts small-molecule organic phosphorus into inorganic phosphorus (phosphate). The ferric ions combine with the phosphate to produce ferric phosphate precipitate, thereby removing phosphorus from the acetamiprid phosphorus-containing wastewater.

[0028] 2. The internal electrolysis packing is made of iron and carbon sintered together. The iron and carbon are sintered at high temperature to form a porous and rigid integral structure. The micropores can increase the specific surface area, improve the reaction contact efficiency, and allow the wastewater to flow smoothly, ensuring the internal electrolysis reaction is complete. In addition, the rigid integral structure can improve the stability of the packing.

[0029] 3. After the wastewater is injected into the annular flow channel from the inlet, it forms a uniform annular flow in the closed loop space. When the water level overflows the top of the serrated guide ring, the water overflows downward due to gravity. The serrated structure of the guide ring cuts the annular water flow into multiple independent streams. Each serrated notch is equivalent to a miniature water distribution port, so that the water flow impacts the surface of the internal electrolysis packing in a dispersed form, ensuring that the packing and wastewater are in full contact and improving the efficiency of the internal electrolysis reaction.

[0030] 4. The residual air after the ozone is completely consumed, mainly nitrogen, with trace amounts of ozone and oxygen, will continue to rise in the device, causing disturbance and stirring in the internal electrolysis section and Fenton section, effectively preventing the internal electrolysis packing from caking and achieving wastewater homogenization.

[0031] 5. The tower body adopts a sawtooth annular weir for water inlet to ensure the uniformity of water inlet. At the same time, the tower body adopts internal electrolysis, Fenton oxidation, ozone oxidation and mud-water separation in sequence according to the wastewater flow direction. The continuous use in a single reactor enables the efficient conversion of organic phosphorus in acephate-containing wastewater, which can achieve an organic phosphorus conversion efficiency of over 99% and excellent comprehensive treatment efficiency.

Detailed Implementation

[0037] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0038] like Figure 1-3As shown, an acetylmethylamine phosphorus-containing wastewater treatment device includes a tower body 1. Inside the tower body 1 are a wastewater distributor 2, an internal electrolytic packing 3, and a hydrogen peroxide distributor 4. The internal electrolytic packing 3 is located below the wastewater distributor 2, and the hydrogen peroxide distributor 4 is located below the internal electrolytic packing 3. An inlet 5 and an outlet 6 are provided on the side of the tower body 1. The inlet 5 is connected to the wastewater distributor 2. Wastewater enters the distributor through the inlet 5 on the tower body 1 and is evenly distributed onto the internal electrolytic packing 3. The internal electrolytic packing 3, made of sintered iron and carbon, forms numerous tiny galvanic cells in the wastewater environment, which are energized by a microcurrent. The function of the process is to break the chemical bonds of large phosphorus molecules in the wastewater, converting them into small organic phosphorus molecules. In addition, iron, as the anode, easily loses electrons to release ferrous ions. As the wastewater continues to flow downwards into the oxidation zone, the ferrous ions in the process encounter hydrogen peroxide introduced by the hydrogen peroxide distributor 4 below. Under acidic conditions, the Fenton reaction occurs, where the ferrous ions act as a catalyst and are converted into ferric ions. At the same time, the Fenton reaction converts the small organic phosphorus molecules into inorganic phosphorus (phosphate). The ferric ions combine with the phosphate to produce ferric phosphate precipitate, thereby removing phosphorus from the acetamiprid phosphorus-containing wastewater.

[0039] The wastewater distributor 2 is a sawtooth annular weir-type distributor. The wastewater distributor 2 includes a guide ring 21 and an annular flow channel 22. The guide ring 21 is concentrically arranged with the tower body 1. The top of the guide ring 21 is sawtooth-shaped. An annular flow channel 22 is provided between the guide ring 21 and the tower body 1. The annular flow channel 22 is connected to the inlet 5. After the wastewater is injected into the annular flow channel 22 from the inlet 5, it forms a circumferentially uniform annular water flow in the closed loop space. When the water level overflows the top of the sawtooth guide ring 21, the water flow overflows downward due to gravity. The sawtooth structure of the guide ring 21 cuts the annular water flow into multiple independent water streams. Each sawtooth notch is equivalent to a miniature water distribution port, so that the water flow impacts the surface of the internal electrolytic packing 3 in a dispersed form, ensuring that the packing and wastewater are in full contact and improving the efficiency of the internal electrolytic reaction.

[0040] The hydrogen peroxide distributor 4 is a perforated pipe distributor. A hydrogen peroxide inlet 41 is provided on the side of the tower body 1, and the hydrogen peroxide inlet 41 is connected to the hydrogen peroxide distributor 4. Hydrogen peroxide is injected through the hydrogen peroxide inlet 41 on the side of the tower body 1 and then enters the perforated pipe distributor inside the tower body 1. The perforated pipe distributor is usually composed of a main pipe and an upward branch pipe. Many small holes with equal spacing and equal diameter are evenly arranged on the upper side of the branch pipe. Hydrogen peroxide flows from the main pipe into the branch pipe and then flows out through the holes of the branch pipe to achieve uniform water distribution. At this time, hydrogen peroxide and wastewater can mix in a countercurrent manner.

[0041] A sieve plate 7 is installed between the internal electrolysis packing 3 and the hydrogen peroxide distributor 4, supporting the internal electrolysis packing 3. On the one hand, the sieve plate 7 firmly supports the internal electrolysis packing 3, which is made of iron-carbon sintering, bears its weight, and maintains the stability of the packing structure, preventing the reaction effect from being affected by the deformation of the packing due to packing accumulation. On the other hand, through the adaptive aperture design on the sieve plate 7, the wastewater to be treated can pass smoothly through the packing layer, ensuring uniform flow of the reaction medium, avoiding blockage and air resistance, ensuring full contact between the packing and the reaction medium, and improving the efficiency of the internal electrolysis reaction.

[0042] The tower body 1 is equipped with an air distribution head 8, and an air distributor is installed outside the tower body 1. The air distribution head 8 is connected to the air distributor and is located below the hydrogen peroxide water distributor 4. The air distribution head 8 distributes air upwards, and air source ozone is introduced into the air distributor, which is a nanobubble generator. The ozone is air source ozone, which has low gas source cost and can effectively control the cost of ozone. The air source ozone enters the nanobubble generator and then enters the air distribution head 8 to form nanobubbles. In the lower part of the oxidation zone, the ozone reacts with the untreated organic phosphorus-containing substances from the Fenton reaction to convert them into inorganic phosphorus, achieving deep oxidation and conversion of organic phosphorus substances and improving treatment efficiency. The nanobubbles have a large specific surface area, increasing contact sites and shortening diffusion distance to accelerate mass transfer; they are also highly stable and uniformly distributed, avoiding uneven reaction areas and improving the efficiency and thoroughness of organic phosphorus removal. The residual air after the ozone is depleted, mainly nitrogen with trace amounts of ozone and oxygen, will continue to rise in the device, causing disturbance and agitation in the internal electrolysis section and Fenton section, effectively preventing the internal electrolysis packing 3 from caking and achieving wastewater homogenization.

[0043] The tower body 1 is also equipped with a mud-water separator 9, which is located below the aerator. The mud-water separator 9 is a sedimentation type mud-water separator with a funnel-shaped cavity structure. The water outlet 6 is located on one side of the mud-water separator 9, and the bottom of the tower body 1 is equipped with a sludge discharge port 10. The mud-water separator 9 below the aerator separates the phosphate sludge from the water through sedimentation. The water outlet 6 and the sludge discharge port 10 realize water discharge and sludge discharge treatment. The inclined inner wall of the funnel shape can guide the flow of the mud-water mixture, slow down the liquid flow rate, and provide sufficient settling time for suspended sludge particles. The conical bottom forms a contraction space that can naturally collect the settled sludge, reduce the sludge residue in the cavity, facilitate subsequent centralized discharge, and improve sludge collection efficiency.

[0044] The working process and principle of the acetylmethylamine phosphorus-containing wastewater treatment device of this utility model are as follows:

[0045] S1. First, hydrogen peroxide is continuously injected from the hydrogen peroxide inlet 41 on the side of the tower body 1, and then enters the hydrogen peroxide distributor 4 inside the tower body 1, i.e., the perforated pipe distributor. The perforated pipe distributor is usually composed of a main pipe and upward branch pipes. Many small holes with equal spacing and equal diameter are evenly arranged on the upper side of the branch pipes. Wastewater flows from the main pipe into the branch pipes and then flows out through the holes in the branch pipes, thereby achieving uniform water distribution. At the same time, air source ozone enters the nanobubble generator, and then enters the gas distribution head 8 to form nanobubbles, which are distributed upwards.

[0046] S2. Then, the acetylamine phosphorus-containing wastewater is injected into the annular flow channel 22 through the inlet 5, forming a circumferentially uniform annular water flow in the closed loop space. When the water level overflows the top of the serrated guide ring 21, the water flow overflows downward due to gravity. The serrated structure of the guide ring 21 cuts the annular water flow into multiple independent water streams. Each serrated notch is equivalent to a miniature water distribution port, so that the water flow impacts the surface of the inner electrolytic packing 3 in a dispersed form, ensuring that the packing is in full contact with the wastewater.

[0047] S3. The sieve plate 7 supports the internal electrolytic packing 3, which is made of iron and carbon sintered. The internal electrolytic packing 3 forms countless tiny galvanic cells in the wastewater environment. Through the action of microcurrent, the chemical bonds of large phosphorus molecules in the wastewater are broken and converted into small organic phosphorus molecules. In addition, iron, as the anode, easily loses electrons and releases ferrous ions.

[0048] S4. As the wastewater continues to flow downwards into the oxidation zone, the ferrous ions in it encounter the hydrogen peroxide introduced by the hydrogen peroxide distributor 4 below. Under acidic conditions, the Fenton reaction occurs, where the ferrous ions act as a catalyst and are converted into ferric ions. At the same time, the Fenton reaction converts small-molecule organic phosphorus into inorganic phosphorus (phosphate). The ferric ions combine with the phosphate to produce ferric phosphate precipitate, thereby removing phosphorus from the acetamiprid phosphorus-containing wastewater.

[0049] S5. Ozone reacts with untreated organophosphorus substances from the Fenton reaction in the lower part of the oxidation zone, converting them into inorganic phosphorus. This achieves deep oxidation and transformation of organophosphorus substances, improving treatment efficiency. Nanobubbles have a large specific surface area, increasing contact sites and shortening diffusion distances to accelerate mass transfer; their high stability and uniform distribution prevent uneven reaction zones, improving the efficiency and thoroughness of organophosphorus removal.

[0050] S6. The residual air after the ozone is depleted, mainly nitrogen, with trace amounts of ozone and oxygen, will continue to rise in the device, causing disturbance and agitation in the internal electrolysis section and Fenton section, effectively preventing the internal electrolysis packing 3 from caking and achieving wastewater homogenization.

[0051] S7. Finally, the sludge-water separator 9 separates the phosphate sludge from the water through sedimentation. The effluent is the phosphorus-content wastewater that meets the standards after phosphorus removal. The effluent outlet 6 and the sludge discharge outlet 10 realize the treatment of effluent and sludge discharge. The funnel-shaped inclined inner wall can guide the flow of the sludge-water mixture, slow down the liquid flow rate, and provide sufficient settling time for suspended sludge particles. The conical bottom forms a contraction space that can naturally collect the settled sludge, reduce the sludge residue in the cavity, facilitate subsequent centralized discharge, and improve sludge collection efficiency.

[0052] S8. The water inlet of tower body 1 adopts a sawtooth annular weir to ensure the uniformity of water intake. At the same time, tower body 1 adopts internal electrolysis, Fenton oxidation, ozone oxidation and mud-water separation in sequence according to the wastewater flow direction. The liquid level of wastewater is generally maintained between the wastewater distributor 2 and the internal electrolysis packing 3. The continuous use in a single reactor enables the efficient conversion of organic phosphorus in acephate-containing wastewater, which can achieve an organic phosphorus conversion efficiency of over 99%. It removes phosphorus from acephate-containing wastewater with excellent comprehensive treatment efficiency. The overall single tower shape has the advantage of small footprint.
