Description

Technical Field

[0001] The invention belongs to the technical field of grid disinfection pools, and in particular relates to a grid disinfection pool which can be used for both normal and emergency purposes and can be quickly switched. Background Art

[0002] In the early stages of my country's development, when the urban sewage system was imperfect, stabilization ponds, as the first water treatment structure in the urban sewage network, played a certain role in reducing pollution and preventing subsequent pipe network blockages. However, due to the weak operation and management of stabilization ponds, many shortcomings and problems were exposed, such as chaotic management; sewage leakage; unsatisfactory water treatment effects; the production of a large amount of harmful gases, and even fermentation to produce biogas; affecting the operation of urban sewage treatment plants, etc. With the continuous development of my country's economy, urban sewage treatment systems in various places are becoming increasingly perfect. Among them, the screen grit chamber has the advantages of small footprint and short hydraulic retention time compared to the stabilization pond, and can prevent pipe network blockage to a certain extent, and has gradually replaced the stabilization pond in some areas.

[0003] The construction of "dual-use" public infrastructure is one of the "three major projects", which requires that the conversion time between the normal use function of the building and the emergency function in times of disasters should not exceed 48 hours. In the period of disaster, the existing disinfection pools mostly use the enhanced disinfection treatment method of "pre-disinfection + septic tank + disinfection" in sewage treatment. However, if this solution is used in "normal" working conditions, it occupies a large area and requires regular cleaning and maintenance of various structures, which is relatively wasteful in "normal" conditions.

[0004] In summary, existing disinfection pools have the problems of slow conversion between "emergency" and "normal" and low utilization efficiency. Summary of the invention

[0005] In view of this, the present invention provides a grid disinfection pool that can be used for both emergency and normal use and can be quickly converted, which can solve the problems of slow conversion between "emergency" and "normal" and low utilization efficiency in existing disinfection pools.

[0006] The present invention is achieved in that:

[0007] The present invention provides a grid disinfection pool that can be quickly converted for both emergency and normal use, wherein the pool comprises a settling chamber and a treatment chamber, wherein a grid assembly is arranged between the settling chamber and the treatment chamber, wherein the grid assembly is used to separate the settling chamber and the treatment chamber and assist the settling chamber in performing sand settling treatment on sewage to prevent suspended solids from clogging the components inside the treatment chamber; a water inlet assembly is arranged on the side of the settling chamber away from the treatment chamber, and a water outlet assembly is arranged on the side of the treatment chamber away from the settling chamber, wherein both the water inlet assembly and the water outlet assembly are four-way arrangements, which are used to facilitate the addition of sewage to be treated and the discharge of treated sewage from multiple directions; one side of the treatment chamber is connected through the disinfection assembly, and the disinfection assembly is used to add disinfectant into the treatment chamber and discharge tail gas generated during the sewage disinfection process;

[0008] The disinfection component includes a disinfectant dosing component, a recoil component, an exhaust gas treatment component and a water quality inspection component. The disinfectant dosing component is connected to the treatment chamber near the grille component, and is used to uniformly add disinfectant to the sewage after sedimentation to reduce the influence of suspended solids in the sewage on the disinfectant treatment effect; the recoil component is connected to the disinfectant dosing component, and is used to flush the disinfectant dosing component to prevent the disinfectant dosing component from being blocked; the front and rear sides of the treatment chamber are connected to the exhaust gas treatment component, and are used to treat toxic gases generated during the sewage treatment process; the water quality inspection component is connected to the side of the treatment chamber away from the sedimentation chamber, and is used to perform water quality inspection on the treated sewage;

[0009] The sedimentation chamber and the treatment chamber are arranged underground, and the disinfection assembly is arranged above ground and connected to the sedimentation chamber and the treatment chamber via a pipeline.

[0010] The technical effects of a grid disinfection pool that can be quickly converted for both emergency and normal use provided by the present invention are as follows: The advantages of this disinfection pool are:

[0011] (1) It solves the problem of sewage treatment during the conversion of "normal and emergency dual-use" projects. The division of labor of the entire tank and control system is simple and clear. Under normal circumstances, the disinfection tank can be used for daily sewage treatment and treatment, but in emergencies such as natural disasters, the disinfection tank can be quickly converted into an enhanced disinfection treatment facility to meet the sewage treatment needs of contaminated areas and buffer zones.

[0012] (2) Combined with the needs of sewage pretreatment and disinfection, the hydraulic retention time of the entire tank is controlled at 2.5h to 3h. Compared with the hydraulic retention time of 24h to 36h in the manure replacement tank, it greatly reduces the floor space and effective volume, and has better economic benefits.

[0013] (3) The disinfection component is located at the rear end of the pretreatment process, which avoids the influence of large-sized suspended solids in the sewage on the disinfection effect; multiple diversion walls are set in the disinfection section to make the disinfectant distribution more uniform and the disinfection effect more thorough.

[0014] (4) In the event of an emergency such as an epidemic or a natural disaster, the treatment capacity can be quickly increased to ensure that sewage is disinfected in a timely manner and reduce the threat to public health; the flexibility of the design allows the facility to be quickly adjusted according to actual needs to adapt to different working environments and sewage treatment requirements.

[0015] (5) Under normal circumstances, the disinfection pool can efficiently treat daily sewage and avoid idle resources. At the same time, it can be put into use immediately when needed, thus improving resource utilization.

[0016] On the basis of the above technical solution, the grid disinfection pool of the present invention which can be quickly converted for both emergency and normal use can also be improved as follows:

[0017] The bottom of the settling chamber and the treatment chamber are both provided with a concrete cushion layer to prevent sewage from infiltrating to avoid soil pollution; the concrete cushion layer at the bottom of the treatment chamber is 150 mm, and the concrete cushion layer at the bottom of the settling chamber is set as a slope structure gradually inclined from the side close to the settling chamber to the side away from the settling chamber, and its inclination angle is 4-6°, so that the suspended solids in the sewage are concentrated and stored at a position away from the settling chamber along the slope to facilitate the collection of suspended solids; and the concrete cushion layer at the connection between the settling chamber and the treatment chamber is integrally arranged with the same height to avoid suspended fixed accumulation;

[0018] The tops of the sedimentation chamber and the treatment chamber are both provided with through openings, the other side of the through openings leads to the ground and is sealed and fixed by a double-layer locked manhole cover.

[0019] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: a concrete cushion layer is arranged at the bottom of the disinfection pool to prevent sewage from penetrating into the soil, prevent harmful substances from polluting groundwater and soil, and protect the ecological environment; by preventing sewage penetration, it ensures that the disinfectant in the sewage treatment process can fully play its role, thereby improving the disinfection effect and treatment efficiency; the concrete cushion layer enhances the sealing of the pool body, reduces the possibility of sewage leakage to the surrounding land, and avoids potential environmental safety problems; the concrete cushion layer enhances the overall structural stability of the pool body and prevents ground deformation caused by land changes or sewage penetration; by preventing sewage penetration and leakage, the concrete cushion layer extends the service life of the pool body and reduces structural damage caused by leakage and penetration.

[0020] Further, the grid assembly includes a hook and a grid, the hook is fixed on the top wall of the sedimentation chamber adjacent to the processing chamber, and the position of the hook faces the direction of the sedimentation chamber; a protrusion is provided at the bottom of the position adjacent to the hook and the grid, a magnetic attraction member is fixed at the middle position of the protrusion, and an adsorption member is fixed at the bottom position of the grid, and the adsorption member is adapted to the magnetic attraction member;

[0021] The hook includes a fixing portion and a stretching portion. The stretching portion is arranged in the middle position of the fixing portion and is made of a hard spring, which is used to facilitate the fixed installation of the grille through a stretching force. The fixing portion is an annular structure, and a slot is provided on one side of the fixing portion. A plug-in is provided at a matching position. The hook with the grille installed is fixed by the cooperation between the slot and the plug-in.

[0022] Furthermore, the grid is an arched structure, with its bending direction facing one side of the sedimentation chamber, so as to further reinforce the grid through the impact of sewage;

[0023] The grid is provided with a plurality of grid bars of the same size, and the grid bars are used to allow water to pass through but prevent suspended solids from passing through.

[0024] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the grille is an arched structure, which can effectively alleviate the vortex and turbulence in the water flow, make the water flow more stable, reduce the flood and turbulence in the water flow, and thus improve the disinfection effect; the design of the arc grille can increase the contact area between the water flow and the grille, and increase the contact and reaction area between the disinfectant and the sewage, thereby improving the disinfection efficiency. The arch faces one side of the sedimentation chamber to effectively prevent sediment from accumulating on the grille, reduce the risk of grille blockage, and ensure smooth water flow. By improving disinfection efficiency and reducing water flow resistance, the design of the arched grille can reduce the total cost of sewage treatment, including the amount of disinfectant used and energy consumption.

[0025] Further, the adjacent through-ports in the four-way structure of the water inlet assembly and the water outlet assembly are spaced 90° apart, and the through-ports penetrating into the sedimentation chamber and the treatment chamber are arranged as an L-shaped structure, one end of which is bent downward and fixed to the inner wall of the sedimentation chamber and the treatment chamber respectively by a bracket, the side wall of the bracket is welded and fixed to the side wall of the sedimentation chamber and the treatment chamber, and the other end is provided with an annular frame, the water inlet assembly and the water outlet assembly are sleeved in the annular frame, and the annular frame is fastened by bolts;

[0026] The connection position of the four-way opening of the water inlet assembly is set as a circular structure, which is used to block the suspended solids in the sewage to prevent them from blocking the opening of the water inlet assembly; the diameters of the three openings of the water inlet assembly away from the sedimentation chamber gradually increase in the direction close to the sedimentation chamber;

[0027] The water inlet assembly is sleeved with a flow meter.

[0028] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the four-way structure is conducive to the sewage entering the disinfection tank more evenly, and the design of the circular structure convergence further optimizes the water inlet flow pattern, reduces the scouring and particle accumulation caused by the local excessive water flow speed, and the circular structure convergence can effectively intercept larger suspended particles to prevent them from entering the subsequent treatment unit of the disinfection tank, avoid blockage and equipment damage, extend the service life of the equipment, and reduce maintenance costs; the three ports can all inject sewage into the sedimentation chamber, avoiding the local high flow rate and vortex phenomenon that may be caused by a single water inlet, thereby improving the uniformity and stability of the water flow. The gradually enlarged straight hole design can reduce the local pressure concentration at the water inlet and enhance the structural stability of the entire four-way; the gradually enlarged diameter port further avoids the occurrence of blockage.

[0029] Furthermore, a plurality of guide walls are arranged inside the treatment chamber, and the guide walls are all arc-shaped structures, fixedly connected to the bottom concrete cushion layer of the treatment chamber, so as to make the disinfection treatment of sewage more thorough; the plurality of guide walls form a spiral structure in the horizontal direction, so as to make multiple collisions with sewage in all directions.

[0030] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the diversion wall can effectively capture floating objects in sewage, reduce the risk of floating objects entering subsequent treatment equipment, and improve the overall treatment efficiency. Through multiple collisions, the diversion wall can promote the separation and precipitation of sediments in sewage, making the subsequent sediment cleaning work more efficient; the diversion wall increases the contact area between sewage and the diversion wall, promotes full contact between sewage and disinfectant, and improves the disinfection effect; the design of the diversion wall can make the disinfectant more evenly distributed in the water flow, ensuring that each part of the sewage can be exposed to enough disinfectant, thereby improving the disinfection effect.

[0031] Furthermore, the disinfectant dosing assembly includes a dosing tube and a motor, the dosing tube includes two sections, namely a fixed section and a rotating section, the fixed section and the rotating section are connected through a slot, one side of the rotating section is fixedly connected to the output shaft of the motor, and the motor is used to drive the rotating section to rotate;

[0032] An arc groove is arranged on one side of the grille close to the treatment chamber, and the dosing tube is arranged in contact with the arc groove on one side of the grille; a plurality of through holes are arranged horizontally on one side of the dosing tube, and the through holes are used to add disinfectant into the interior of the treatment chamber.

[0033] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the rotating section of the dosing pipe can be rotated to fit into the arc groove of the grille to block its own drug outlet hole to prevent sewage from backflowing through the drug outlet hole, thereby ensuring that the disinfectant can fully interact with the sewage and avoid reducing the efficacy of the drug; preventing backflow can protect the dosing pipe and related equipment from corrosion and damage to the equipment by sewage, thereby extending the service life of the equipment.

[0034] Furthermore, one end of the backflush assembly is through-connected to the end of the dosing tube, and the other end is through-connected to the output port of the water pump, so as to backflush the interior of the dosing tube through the punching pressure of the water in the water pump to avoid clogging of the disinfectant; the backflush assembly and the dosing tube are set at an angle of 45°.

[0035] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: concentrated disinfectant is easy to crystallize or precipitate, resulting in blockage of the dosing tube. The backflushing component can effectively remove the sediment and crystals in the dosing tube, keep the pipeline unobstructed, and ensure the continuity and stability of the dosing process. Blockage will cause the internal pressure of the dosing tube to increase, and even cause the pipeline to rupture. Regular backflushing can effectively reduce the occurrence of blockage, thereby extending the service life of the dosing tube and reducing maintenance and replacement costs.

[0036] Furthermore, the exhaust gas treatment component includes a biogas pipe, a processor and a high-altitude emission pipe. The biogas pipes include multiple ones, which are respectively connected to different positions of the sedimentation chamber and the treatment chamber. One end of the processor is connected to the multiple biogas pipes for treating the gas; the top of the processor is connected to the high-altitude emission pipe for discharging the treated gas into the air.

[0037] The beneficial effects of adopting the above-mentioned improvement scheme are: after being processed by the processor, the biogas becomes carbon dioxide and water, which are common components in nature and have relatively little impact on the environment when discharged into the air. In contrast, direct discharge of biogas will increase the concentration of greenhouse gases and aggravate climate change.

[0038] Furthermore, the water quality inspection component is a pipe structure, one end of which extends out of the ground and the other end is connected to the top of the water outlet component, and is used to pump out treated water from the water outlet component for water quality inspection.

[0039] Compared with the prior art, the beneficial effects of the grid disinfection pool provided by the present invention that can be quickly converted for both emergency and normal use are as follows:

[0040] (1) It solves the problem of sewage treatment during the conversion of "normal and emergency dual-use" projects. The division of labor of the entire tank and control system is simple and clear. Under normal circumstances, the disinfection tank can be used for daily sewage treatment and treatment, but in emergencies such as natural disasters, the disinfection tank can be quickly converted into an enhanced disinfection treatment facility to meet the sewage treatment needs of contaminated areas and buffer zones.

[0041] (2) Combined with the needs of sewage pretreatment and disinfection, the hydraulic retention time of the entire tank is controlled at 2.5h to 3h. Compared with the hydraulic retention time of 24h to 36h in the manure replacement tank, it greatly reduces the floor space and effective volume, and has better economic benefits.

[0042] (3) The disinfection component is located at the rear end of the pretreatment process, which avoids the influence of large-sized suspended solids in the sewage on the disinfection effect; multiple diversion walls are set in the disinfection section to make the disinfectant distribution more uniform and the disinfection effect more thorough.

[0043] (4) In the event of an emergency such as an epidemic or a natural disaster, the treatment capacity can be quickly increased to ensure that sewage is disinfected in a timely manner and reduce the threat to public health; the flexibility of the design allows the facility to be quickly adjusted according to actual needs to adapt to different working environments and sewage treatment requirements.

[0044] (5) Under normal circumstances, the disinfection pool can efficiently treat daily sewage and avoid idle resources. At the same time, it can be put into use immediately when needed, thus improving resource utilization. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The sedimentation chamber 10 and the treatment chamber 20 are arranged underground, and the disinfection assembly 50 is arranged above ground and connected to the sedimentation chamber 10 and the treatment chamber 20 through a pipeline.

[0058] Among them, in the above technical scheme, the bottom of the sedimentation chamber 10 and the treatment chamber 20 are both provided with a concrete cushion layer to prevent sewage from infiltration to avoid soil pollution; the concrete cushion layer at the bottom of the treatment chamber 20 is 150 mm, and the concrete cushion layer at the bottom of the sedimentation chamber 10 is set to a slope structure gradually inclined from the side close to the sedimentation chamber 10 to the side away from the sedimentation chamber 10, and its inclination angle is 4-6°, which is used to make the suspended solids in the sewage be concentrated and stored at a position away from the sedimentation chamber 10 along the slope to facilitate the collection of suspended solids; and the concrete cushion layer at the connection between the sedimentation chamber 10 and the treatment chamber 20 is set in one piece, with the same height, to avoid suspended fixed accumulation;

[0059] There are openings at the tops of the sedimentation chamber 10 and the treatment chamber 20, and the other side of the openings leads to the ground and is sealed and fixed by a double-layer locked manhole cover.

[0060] Further, in the above technical solution, the grid assembly 60 includes a hook 61 and a grid 62, the hook 61 is fixed on the top wall of the sedimentation chamber 10 and the processing chamber 20, and the position of the hook is facing the direction of the sedimentation chamber 10; the bottom of the position adjacent to the hook 61 and the grid 62 is provided with a protrusion, the middle position of the protrusion is fixed with a magnetic suction member, and the bottom position of the grid 62 is fixed with an adsorption member, and the adsorption member is adapted to the magnetic suction member;

[0061] The hook 61 includes a fixing portion 611 and a stretching portion 612. The stretching portion 612 is arranged in the middle position of the fixing portion 611 and is made of a hard spring for facilitating the fixed installation of the grille 62 through a stretching force. The fixing portion 611 is an annular structure with a slot on one side thereof and a plug-in at a matching position. The hook 61 with the grille 62 installed is fixed by the cooperation between the slot and the plug-in.

[0062] Furthermore, in the above technical solution, the grid 62 is an arched structure, and its bending direction is toward one side of the sedimentation chamber 10, which is used to further reinforce the grid 62 through the impact of sewage;

[0063] The grid 62 is provided with a plurality of grid bars of the same size, and the grid bars are used to allow water to pass through but prevent suspended solids from passing through.

[0064] Further, in the above technical solution, the adjacent through-ports in the four-port structure of the water inlet assembly 30 and the water outlet assembly 40 are spaced 90° apart, and the through-ports penetrating the inlet settling chamber 10 and the treatment chamber 20 are set as an L-shaped structure, one end of which is bent downward and fixed to the inner walls of the settling chamber 10 and the treatment chamber 20 respectively by a bracket, the side wall of the bracket is welded and fixed to the side wall of the settling chamber 10 and the treatment chamber 20, and the other end is provided with an annular frame, the water inlet assembly 30 and the water outlet assembly 40 are sleeved in the annular frame, and the annular frame is fastened by bolts;

[0065] The connection position of the four-way opening of the water inlet assembly 30 is set to a circular structure, which is used to block the suspended solids in the sewage to prevent them from clogging the opening of the water inlet assembly 30; the diameters of the three openings of the water inlet assembly 30 away from the sedimentation chamber 10 gradually increase in the direction close to the sedimentation chamber 10;

[0066] The water inlet assembly 30 is sleeved with a flow meter.

[0067] Furthermore, in the above technical solution, a plurality of guide walls 21 are arranged inside the treatment chamber 20. The guide walls 21 are all arc-shaped structures and are fixedly connected to the bottom concrete cushion layer of the treatment chamber 20 to make the disinfection treatment of sewage more thorough; the plurality of guide walls 21 form a spiral structure in the horizontal direction to perform multiple collisions on the sewage in all directions.

[0068] Furthermore, in the above technical solution, the disinfectant dosing assembly 51 includes a dosing tube 511 and a motor 512. The dosing tube 511 includes two sections, namely a fixed section and a rotating section. The fixed section and the rotating section are connected through a slot. One side of the rotating section is fixedly connected to the output shaft of the motor 512. The motor 512 is used to drive the rotating section to rotate.

[0069] An arc groove is provided on one side of the grille 62 close to the treatment chamber 20 , and the dosing tube 511 is arranged in contact with the arc groove on one side of the grille 62 ; a plurality of through holes are horizontally provided on one side of the dosing tube 511 , and the through holes are used to add disinfectant into the interior of the treatment chamber 20 .

[0070] Furthermore, in the above technical solution, one end of the backflush assembly 52 is through-connected to the end of the dosing tube 511, and the other end is through-connected to the output port of the water pump, so as to backflush the interior of the dosing tube 511 through the punching pressure of the water in the water pump to avoid clogging of the disinfectant; the backflush assembly 52 and the dosing tube 511 are set at an angle of 45°.

[0071] Furthermore, in the above technical scheme, the exhaust gas treatment component 53 includes a biogas pipe 531, a processor 532 and an altitude discharge pipe 533. The biogas pipe 531 includes multiple pipes, which are respectively connected to different positions of the sedimentation chamber 10 and the treatment chamber 20. One end of the processor 532 is connected to the multiple biogas pipes 531 for treating the gas; the top of the processor 532 is connected to the altitude discharge pipe 533 for discharging the treated gas into the sky.

[0072] The process of processing biogas into harmless gases such as carbon dioxide and water usually involves multi-step chemical or biological treatment methods.

[0073] (1) The biogas must first be pre-treated to remove impurities in the biogas, such as gaseous, liquid, and solid impurities. The biogas may contain moisture, which needs to be removed to make the subsequent processing more efficient. The dehydrator or condenser inside the processor 532 removes the moisture.

[0074] (2) Oxidation of pre-treated biogas: Oxidation of methane (CH4) and other organic compounds in the biogas. This can be achieved using chemical oxidants. Under high temperature and high pressure conditions, the organic compounds in the biogas react with oxygen to produce carbon dioxide and water.

[0075] The chemical formula is: CH4+2O2→CO2+2H2O;

[0076] (3) Purification: Biogas may contain harmful components, such as hydrogen sulfide (H2S), volatile organic compounds (VOCs), etc. These harmful components need to be removed through a purification process. The processor 532 contains activated carbon adsorbent and aluminosilicate catalyst to convert harmful components into harmless compounds.

[0077] (4) Volatile organic compound treatment: Under high temperature and pressure conditions, volatile organic compounds are oxidized into carbon dioxide and water using a catalyst (such as platinum or palladium).

[0078] (5) Sulfur dioxide treatment: Hydrogen sulfide in biogas will be converted into sulfur dioxide during the treatment process, and the sulfur dioxide will be adsorbed using the adsorbent pentanol.

[0079] Furthermore, in the above technical solution, the water quality inspection component 54 is a pipe structure, one end of which extends out of the ground and the other end is connected to the top of the water outlet component 40, so as to pump out the treated water from the water outlet component 40 for water quality inspection.

[0080] The disinfection pool is mainly used as a screen sand settling function when it is used in "normal" times. The entire disinfection pool is divided into two compartments at the screen position. The first compartment is a sewage pretreatment compartment, which plays a role in removing large-sized suspended solids and sand in sewage to prevent clogging of subsequent sewage pipe networks. A 150mm thick concrete cushion is made under the pool body. The bottom cushion of the first compartment is set with a slope of 5% for the collection of waste and sand, which is convenient for cleaning and reduces the impact on the sewage flow line of the subsequent disinfection compartment. The hydraulic retention time of the first compartment can be designed according to 0.5h~1h.

[0081] The tank body activates its disinfection tank function under "emergency" conditions. The first upstream grid mainly removes large-sized suspended solids and sediment in sewage, which can reduce the impact of suspended impurities on the subsequent disinfection effect. The second downstream grid is the disinfection grid. Through the disinfectant dosing device in the equipment room, the disinfectant is evenly added through the porous pipes installed in the grille. The hydraulic retention time of the disinfection unit can be designed according to 2h, and the diversion wall can make the disinfection more sufficient and thorough. In addition, through the online water quality monitoring device in the equipment room, water is taken from the sewage outlet four-way position, and the dosage is controlled by real-time monitoring of the effluent water quality. A remote flow meter is set at the sewage inlet, and the dosage can also be adjusted in real time according to the water volume.

[0082] The cleaning time of the entire pool can be controlled within 30 days. Since the dosing pipe is a porous pipe and is designed with a pipe backwashing device, the dosing pipe should be flushed and maintained once a month to avoid pipe blockage.

[0083] Sewage tail gas under "emergency" conditions should be disinfected before discharge. Two ventilation pipes are set at the inspection well position of the pool body. After being disinfected by the high-efficiency tail gas treatment device in the equipment room, it is extended to the roof of the equipment room for discharge.

[0084] The specific workflow of water quality testing is as follows:

[0085] Step 1: Use the water quality inspection component 54 to sample the treated water flowing out of the water outlet component 40. After sampling, bring the sample back to the laboratory for testing as soon as possible to avoid changes in the sample during transportation. If the test cannot be performed immediately, store the sample at 4-6°C;

[0086] Step 2: The water sample is initially filtered through filter papers of 0.45 μm and 0.22 μm in turn to remove solid impurities such as suspended matter;

[0087] Step 3: Divide the water samples after preliminary filtration into different centrifuge tubes, preheat the centrifuge, ensure that the temperature of the centrifuge tubes and the centrifuge rotating platform is consistent, put the samples into the centrifuge, adjust the centrifugal speed to 3000rpm, and the time is 20 minutes;

[0088] Step 4: Use a pipette or tubular valve bend to suck up the supernatant and put it into different clean test tubes, leaving the sediment in the centrifuge tube for subsequent testing;

[0089] Step 5: Use a pH meter to measure the pH value of the water sample in a test tube to ensure that the pH value of the treated water sample meets the specified range, usually 6.5-8.5;

[0090] Step 6: Detect the number of infectious bacteria in the second test tube water sample by culture method. Drop the water sample into the culture medium and culture it at a specific temperature. Observe the number of colonies in the culture medium and calculate the number of infectious bacteria.

[0091] Step 7: Use a COD detector or chemical reagent to determine the chemical oxygen demand of the water sample in the third test tube, use the Nessler quantitative method to determine the ammonia nitrogen content in the water sample in the fourth test tube, and use the nitrite method to determine the phosphorus content in the water sample in the fifth test tube;

[0092] Step 8: Use atomic absorption spectrometry to detect heavy metals in the sixth test tube; use gas chromatography to test organic pollutants in the seventh test tube;

[0093] Step 9: Record all test results in the sample test form and analyze the test results to ensure that the treated water quality meets relevant environmental protection standards and regulations.

[0094] Specifically, the principle of the present invention is: the disinfection pool is mainly used as a screen sand settling function when it is used "normally". The entire disinfection pool is divided into two compartments at the screen position. The first compartment is a sewage pretreatment compartment, which plays a role in removing large-sized suspended solids and sand in sewage to prevent clogging of subsequent sewage pipe networks. A 150mm thick concrete cushion is made under the pool body. The bottom cushion of the first compartment is set with a slope of 5% for collecting waste and sand, which is convenient for cleaning and reduces the impact on the sewage flow line of the subsequent disinfection compartment. The hydraulic retention time of the first compartment can be designed according to 0.5h~1h.

[0095] The tank body activates its disinfection tank function under "emergency" conditions. The first upstream grid mainly removes large-sized suspended solids and sediment in sewage, which can reduce the impact of suspended impurities on the subsequent disinfection effect. The second downstream grid is the disinfection grid. Through the disinfectant dosing device in the equipment room, the disinfectant is evenly added through the porous pipes installed in the grille. The hydraulic retention time of the disinfection unit can be designed according to 2h, and the diversion wall can make the disinfection more sufficient and thorough. In addition, through the online water quality monitoring device in the equipment room, water is taken from the sewage outlet four-way position, and the dosage is controlled by real-time monitoring of the effluent water quality. A remote flow meter is set at the sewage inlet, and the dosage can also be adjusted in real time according to the water volume.

[0096] The cleaning time of the entire pool can be controlled within 30 days. Since the dosing pipe is a porous pipe and is designed with a pipe backwashing device, the dosing pipe should be flushed and maintained once a month to avoid pipe blockage.

[0097] Sewage tail gas under "emergency" conditions should be disinfected before discharge. Two ventilation pipes are set at the inspection well position of the pool body. After being disinfected by the high-efficiency tail gas treatment device in the equipment room, it is extended to the roof of the equipment room for discharge.

[0098] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
