Description

TECHNICAL FIELD

[0001] The present application relates to the field of energy saving and environmental protection sewage treatment, and particularly relates to a double-mode water quality purification and ecological reconstruction method for river outlet. BACKGROUND

[0002] With the continuous acceleration of urbanization process in China, the construction scale of urban drainage system is also increasing year by year. The end of the urban drainage system is the river inlet sewage outlet located along the river. The effluent pollution of these river inlet sewage outlets is the total root cause of urban river water pollution and eutrophication, and even black odor. This is because the combined system drainage pipeline has accumulated a large amount of sludge due to small flow during "sunny days"; the rainwater pipeline of the separated system also has the problem of sludge accumulation due to the problem of sewage pipeline mixing. When it rains, the sludge accumulated in the pipeline of the combined system drainage pipeline or the rainwater pipeline of the separated system is washed into the river inlet sewage outlet and enters the surface water, causing eutrophication and even black odor. Therefore, the surface water receiving the river inlet sewage outlet usually presents the phenomenon of "clear on sunny days and black on rainy days", so it is urgent to implement timely and efficient purification for the rain pollution problem of the river inlet sewage outlet.

[0003] In summary, the market urgently needs a new device that can solve the effluent pollution problem of the river inlet sewage outlet at the end of the urban drainage system, the food chain construction of the surface water receiving the river inlet sewage outlet, and the recovery of the water ecological system. SUMMARY

[0004] The technical problem to be solved by the present application is to overcome the defect of repeated pollution of the water body of the river inlet sewage outlet in the prior art, and to provide a double-mode water quality purification and ecological reconstruction method for river outlet.

[0005] The present application solves the above technical problems by the following technical solutions:

[0006] A double-mode water quality purification and ecological reconstruction method for river outlet comprises: a control assembly starts a detection assembly to monitor the sewage inside an ecological purification device, wherein the ecological purification device is arranged in the surface water of the river inlet sewage outlet; the control assembly judges the water quality in the ecological purification device according to the monitoring result of the detection assembly; when the water quality is in a first standard range, the control assembly starts a water purification assembly, and the water purification assembly transports a purification agent to the ecological purification device to mix with the sewage; when the water quality is in a second standard range, the control assembly starts a repair assembly, and the repair assembly transports probiotic liquid and beneficial algal liquid to the ecological purification device.

[0007] In this solution, the method can control the purification and restoration of the water body according to the judgment of different water quality conditions. The detection component can monitor the water quality inside the ecological purification device in real time. The control component can judge the water quality inside the ecological purification device based on the monitoring results of the detection component. Based on the judgment results of the water quality, the control component can selectively start different processing components to meet the processing needs under different water quality conditions. When the water quality is within the first standard range, the control component starts the water purification component, which mixes the purification agent with the sewage. These purification agents may have the functions of decomposing pollutants, removing odors, sterilizing and disinfecting, etc. The purification agent reacts with the sewage to achieve the effect of purifying the water body; when the water quality is within the second standard range, the control component starts the restoration component, which delivers probiotic liquid and beneficial algae liquid into the ecological purification device. Probiotics and beneficial algae liquid have the effect of ecological restoration in the water body, which can promote the balance of microorganisms in the water body, improve the ecological environment of the water body, help to degrade organic matter, reduce new pollutants (especially persistent organic pollutants, antibiotics, endocrine disruptors, etc. have good treatment effect), increase oxygen content, and reduce pollution. In summary, this method realizes the directional purification and ecological restoration of sewage by monitoring the water quality in real time and starting different processing components according to the monitoring results. This method can adapt to the processing needs under different water quality conditions, and help to maintain the health of the water body and the good state of the environment.

[0008] Preferably, the water purification component delivers the purification agent into the ecological purification device for mixing with the sewage includes: the water purification component delivers the purification agent into the ecological purification device along the circumferential direction of the ecological purification device.

[0009] In this solution, the purification agent is mixed with the sewage to achieve the purification and improvement of the sewage. The function of the water purification component is to introduce the purification agent into the ecological purification device and mix it with the sewage, thereby achieving the purification of the sewage. The purification agent can have chemical, biological or other properties, which can promote the decomposition, oxidation, precipitation or removal of pollutants to reduce or eliminate harmful substances in the sewage. The water purification component delivers the purification agent into the ecological purification device along the circumferential direction of the ecological purification device, which helps to ensure that the purification agent can be evenly distributed in the sewage. Compared with the single-direction spraying agent method, this solution can cover more areas inside the ecological purification device, avoid the residual pollutants in local areas, and improve the probability that various pollutants in the sewage can contact the purification agent for effective treatment, so that the agent and the sewage are fully mixed, thereby improving the purification effect and accelerating the contact reaction process between the purification agent and the sewage, thereby improving the efficiency of sewage purification. This helps to achieve better purification effect in a shorter time.

[0010] Preferably, the water purification assembly transports the purification reagent into the ecological purification device along the circumferential direction of the ecological purification device includes: the water purification assembly sprays the purification reagent onto the filler block in the ecological purification device, and the control assembly starts the ultraviolet lamp to irradiate the filler block.

[0011] In this scheme, by spraying the purification reagent onto the filler block in the ecological purification device and cooperating with the irradiation of the ultraviolet lamp, efficient purification of sewage is realized. The water purification assembly sprays the purification reagent onto the filler block in the ecological purification device, which can be targeted and concentrated on the surface of the filler block to increase the contact area and contact time with the sewage, which helps to strengthen the chemical reaction and physical action between the purification reagent and the sewage, and improves the purification effect. The ultraviolet lamp has the functions of sterilization and disinfection, and by radiating ultraviolet light, it can destroy the DNA of microorganisms, thereby killing or losing their living ability. By directing the ultraviolet lamp to irradiate the filler block, the microorganisms and pathogens in the sewage can be further reduced or eliminated under the action of the purification reagent; the synergistic effect of the purification reagent and the ultraviolet light is realized, the purification reagent can react with the pollutants in the sewage, and the ultraviolet light can kill microorganisms, thereby forming a more effective purification environment on the surface of the filler block, improving the purification effect and purification efficiency, and making the sewage treatment process more rapid and effective.

[0012] Preferably, the control assembly determines the water quality in the ecological purification device according to the monitoring result of the detection assembly includes: when the water quality in the ecological purification device is in the first standard range, the control assembly closes the liquid delivery of the repair assembly, and at the same time opens the liquid delivery of the water purification assembly, sprays hydrogen peroxide, chlorine dioxide solution or ozone onto the filler block; when the water quality in the ecological purification device is in the second standard range, the control assembly adjusts the first metering pump of the water purification assembly to the closed state and at the same time operates the second metering pump of the repair assembly, sprays probiotic liquid and beneficial algal liquid onto the filler block.

[0013] In the present scheme, the water quality in the ecological purification device is judged by the control assembly according to the water quality monitored by the detection assembly, and different operations are performed according to the judgment result, so as to realize accurate treatment of the sewage. When the water quality in the ecological purification device is in the first standard range, first, the liquid delivery of the repair assembly is closed to stop the delivery of probiotic liquid and beneficial algal liquid, and the liquid delivery channel of the water purification assembly is opened, and the control assembly starts the water purification assembly to spray purification reagents such as hydrogen peroxide, chlorine dioxide solution or ozone onto the filler block. These purification reagents can be mixed with sewage inside the ecological purification device to achieve purification of the sewage. When the water quality in the ecological purification device is in the second standard range, the first metering pump of the water purification assembly is adjusted to the closed state, and the second metering pump of the repair assembly is operated to spray probiotic liquid and beneficial algal liquid onto the filler block, so as to realize ecological repair of the sewage. Through the control assembly, the operation of the water purification and repair assemblies is flexibly adjusted according to different water quality, so as to realize accurate treatment of the sewage. The technical effect of such a treatment can ensure that the ecological purification device can provide the best treatment effect under different conditions, so as to maintain the health of the water body and the good state of the environment.

[0014] Preferably, the control assembly judges the water quality in the ecological purification device according to the monitoring result of the detection assembly, which comprises: when the water quality in the ecological purification device is in the first standard range, the control assembly adjusts the light wavelength range of the ultraviolet lamp tube to 100-400nm; when the water quality in the ecological purification device is in the second standard range, the control assembly adjusts the light wavelength range of the ultraviolet lamp tube to 400-760nm.

[0015] In the present scheme, the light wavelength of the ultraviolet lamp in the ecological purification device is adjusted according to the water quality monitored by the detection assembly through the control assembly, so as to effectively treat different types of pollutants in the sewage. When the water quality in the ecological purification device is in the first standard range, the control assembly adjusts the light wavelength range of the ultraviolet lamp tube to 100-400 nm, and the ultraviolet light has strong sterilization, disinfection and oxidation effect, which can effectively destroy the DNA of microorganisms, kill bacteria, viruses and other microorganisms, and at the same time promote the oxidation reaction of organic matter in the sewage, thereby purifying the sewage. When the water quality in the ecological purification device is in the second standard range, the control assembly adjusts the light wavelength range of the ultraviolet lamp tube to 400-760 nm, and the ultraviolet light has the ability of sterilization, disinfection and oxidation reaction, and can also specifically treat organic matter and new pollutants in the sewage, especially has good treatment effect on persistent organic pollutants, antibiotics, endocrine disruptors and other new pollutants, thereby realizing ecological restoration effect. Realize accurate treatment of microorganisms and organic pollutants in sewage. This technical effect can provide the most suitable light conditions according to different situations, thereby enhancing the treatment effect of the ecological purification device and ensuring that the water body is effectively purified and ecologically restored.

[0016] Preferably, the dual-mode water purification and ecological reconstruction method for river outlet also includes: the control assembly starts the detection assembly to monitor the purification reagent in the reagent storage box and / or the microbial population; the control assembly analyzes the monitoring results of the detection assembly to determine whether to issue a liquid supplement prompt to the worker.

[0017] In the present scheme, the water quality in the ecological purification device is monitored by the detection assembly, and the purification reagent and / or microbial population in the reagent storage box are also monitored during the treatment process, so as to realize the monitoring and management of the sewage treatment process. Through regular or real-time monitoring, the purification effect and water quality change of the sewage can be understood, which helps to evaluate whether the sewage treatment effect meets the expectation and whether further treatment or adjustment is needed. If the detection result shows that the reagent concentration is insufficient or the microbial population state is not ideal, the control assembly can issue a liquid supplement prompt and specific treatment suggestion to the worker. This helps to ensure the continuous operation and effect of the ecological purification device, can improve the stability, efficiency and effect of sewage treatment, and at the same time reduces manual intervention and saves manpower.

[0018] Preferably, the dual-mode water purification and ecological reconstruction method for river outlet also includes: the control assembly controls the turbulence assembly to work to promote the flow of sewage in the sewage purification device; the control assembly controls the turbulence assembly to do extension and contraction movement to adjust the position of the plug flow impeller in the barrel.

[0019] In this scheme, by controlling the working and telescopic motion of the turbulence assembly, the flow of sewage in the device is enhanced. The enhancement and regulation of the flow of sewage in the ecological purification device are achieved, which helps to mix the sewage and purification agents, microorganisms and other substances, so that they can fully contact and react, improving the efficiency and effect of sewage treatment. By adjusting the telescopic motion of the turbulence assembly, it can adapt to a wider range of water level requirements. The position of the propeller in the cylinder can affect the direction and speed of the sewage flow. By adjusting the position of the propeller, the flow pattern of the sewage in the device can be optimized to be more uniform and efficient. This helps to ensure that the sewage is fully treated and purified in the device.

[0020] Preferably, the dual-mode water quality purification and ecological reconstruction method for river outlet also includes: the control assembly starts the detection assembly to monitor the water flow velocity inside the ecological purification device; the control assembly judges whether to send a cleaning reminder to the staff according to the monitoring result of the detection assembly.

[0021] In this scheme, a cleaning reminder is sent according to the monitoring result to ensure the normal operation of sewage treatment. The water flow velocity is one of the key indicators to measure the flow degree of sewage in the device. By monitoring the water flow velocity in real time, the flow state of sewage in the device can be understood, whether there are problems such as blockage, accumulation or excessive flow rate. If the monitoring result shows that the water flow velocity is lower than the preset standard range, it may be due to the blockage of external pollutants and impurities affecting the inflow of sewage into the device. The control assembly will send a cleaning reminder to the staff, which can quickly realize the inspection, maintenance and cleaning of the ecological purification device through warning, to ensure smooth water flow and good treatment effect, which helps to reduce equipment failure and downtime, and improves the reliability and maintenance efficiency of the sewage treatment system.

[0022] Preferably, the dual-mode water quality purification and ecological reconstruction method for river outlet also includes: the control assembly adjusts the height of the adjusting rod of the sewage purification device to change the size of the upper opening and the size of the bottom opening of the purification device.

[0023] In this scheme, by adjusting the height of the adjusting rod of the sewage purification device, the size of the upper opening and the size of the bottom opening of the purification device are changed, so as to realize the adjustment of the water flow state in the ecological purification device. By adjusting the height of the adjusting rod, the size of the channel for sewage entering the purification device and the size of the channel for sewage flowing out of the purification device can be changed, and the water flow velocity and water flow rate entering and flowing out of the device can be adjusted. At the same time, the change of the purification device in the height direction caused by the adjusting rod can make the device meet more water level requirements. According to different water level requirements and sewage load, the channel size of the device can be adjusted to achieve the best water flow state and treatment effect.

[0024] Preferably, the river outlet dual-mode water purification and ecological reconstruction method further comprises: the ecological purification device discharges the sewage treated or containing the microbial population from the bottom opening thereof and diffuses to the surface water body in the syncline direction through the guide bottom plate.

[0025] In this scheme, the sewage can diffuse to the surface water body in the syncline direction through the design of the guide bottom plate, and the sewage treated or containing the microbial population can be discharged from the bottom opening. The discharged sewage is guided by the guide bottom plate at the bottom, so that it diffuses in the syncline direction at the position of the outlet. The design of the guide bottom plate can be adjusted as needed to ensure that the discharged water treated or repaired can be properly dispersed and diffused without being concentrated in a certain area, which helps to quickly dilute and disperse the discharged water, thereby improving the purification and repair effect.

[0026] The positive progress effect of the present application is that:

[0027] This method can achieve the purpose of purifying and repairing the water body according to the judgment of different water quality conditions. By starting the detection assembly, the water quality inside the ecological purification device can be monitored in real time. This includes detecting various parameters such as pollutant concentration, microbial quantity, oxygen content, etc. The control assembly can judge the water quality inside the ecological purification device according to the monitoring results of the detection assembly. Based on the judgment result of the water quality, the control assembly can selectively start different processing assemblies to meet the processing needs under different water quality conditions. When the water quality is in the first standard range, the control assembly starts the water purification assembly, which mixes the purification agent with the sewage. These purification agents may have the functions of decomposing pollutants, removing odors, sterilizing and disinfecting, etc. The purification agent reacts with the sewage to achieve the effect of purifying the water body; when the water quality is in the second standard range, the control assembly starts the repair assembly, which delivers probiotic liquid and beneficial algal liquid into the ecological purification device. The probiotic and beneficial algal liquid has the effect of ecological repair in the water body, which can promote the microbial balance in the water body, improve the ecological environment of the water body, help to degrade organic matter, reduce new pollutants (especially the new pollutants such as persistent organic pollutants, antibiotics, endocrine disruptors, etc. have good treatment effect), increase oxygen content, and reduce pollution. In summary, this method realizes directional purification and ecological repair of sewage by monitoring water quality in real time and starting different processing assemblies according to the monitoring results. This method can adapt to the processing needs under different water quality conditions, and is helpful to maintain the health of the water body and the good state of the environment.

[0053] Please refer to Figures 1 to 3 A dual-mode water quality purification and ecological reconstruction method for river outlet includes:

[0054] Step S1: the control component starts the detection component to monitor the sewage inside the ecological purification device 1000, wherein the ecological purification device 1000 is arranged in the surface water body of the river inlet sewage outlet;

[0055] Step S2: the control component judges the water quality condition in the ecological purification device 1000 according to the monitoring result of the detection component;

[0056] Step S3: when the water quality is in the first standard range, the control component starts the water purification component, and the water purification component transports the purification reagent to mix with the sewage inside the ecological purification device 1000;

[0057] Step S4: when the water quality is in the second standard range, the control component starts the repair component, and the repair component transports the probiotic liquid and beneficial algal liquid into the ecological purification device 1000.

[0058] This method can achieve the purpose of purifying and restoring water bodies according to the judgment of different water quality conditions. By starting the detection component, the water quality inside the ecological purification device 1000 can be monitored in real time. This includes detecting various parameters such as pollutant concentration, microbial quantity, oxygen content, etc. The control component can judge the water quality inside the ecological purification device 1000 based on the monitoring results of the detection component. Based on the judgment results of the water quality, the control component can selectively start different processing components to meet the processing needs under different water quality conditions. When the water quality is in the first standard range, that is, when the monitoring probe 8 in the detection component monitors that the water quality of the water entering the ecological purification device 1000 is poor, the "emergency water purification mode" is run through the electric control box 3 in the control component, and the purification component is started to mix the purification reagent with the sewage. These purification reagents may have the functions of decomposing pollutants, removing odors, sterilizing and disinfecting, etc., and by reacting with the sewage, the effect of purifying the water body is achieved; when the water quality is in the second standard range, that is, when the monitoring probe 8 monitors that the water quality of the water in the ecological purification device 1000 is good, the electric control box 3 runs the "ecological restoration mode", at this time the control component starts the restoration component, which delivers probiotic liquid and beneficial algal liquid into the ecological purification device 1000. The probiotic and beneficial algal liquid has the effect of ecological restoration in the water body, can promote the balance of microorganisms in the water body, improve the ecological environment of the water body, help to degrade organic matter, reduce new pollutants (especially have good treatment effect on persistent organic pollutants, antibiotics, endocrine disruptors, etc. New pollutants), improve oxygen content, and reduce pollution. In summary, this method realizes the directional purification and ecological restoration of sewage by monitoring the water quality in real time and starting different processing components according to the monitoring results. This method can adapt to the processing needs under different water quality conditions, and is helpful to maintain the health of the water body and the good state of the environment.

[0059] As Figures 1 to 3As shown, the water purification assembly transports the purification reagent into the interior of the ecological purification device 1000 for mixing with the sewage, which includes: the water purification assembly transports the purification reagent into the interior of the ecological purification device 1000 along the circumferential direction of the ecological purification device 1000; in this embodiment, a ring-shaped infusion pipe is arranged in the interior of the ecological purification device 1000, the diameter of the ring-shaped infusion pipe is smaller than the inner diameter of the cylinder of the ecological purification device 1000, and a plurality of medicine injection holes are arranged at the bottom of the ring-shaped infusion pipe in a spaced manner, the medicine injection holes are located above the filler block, the water purification assembly sprays the purification reagent onto the filler block through the medicine injection holes of the ring-shaped infusion pipe, and the control assembly starts the ultraviolet lamp tube 6 to irradiate the filler block, and the control assembly adjusts the light wavelength range of the ultraviolet lamp tube 6 to 100-400 nm; the purification reagent is sprayed into the interior of the ecological purification device 1000 along the circumferential direction from the ring-shaped infusion pipe, which helps to ensure that the purification reagent can be uniformly distributed in the sewage. Compared with the way of spraying the reagent in a single direction, the present scheme can cover more areas in the ecological purification device 1000, avoid the residual pollutants in the local area, and improve the probability that various pollutants in the sewage can contact the purification reagent, so as to effectively treat the pollutants, mix the reagent and the sewage sufficiently, thereby improving the purification effect and accelerating the contact reaction process of the purification reagent and the sewage, thereby improving the efficiency of sewage purification. This helps to achieve better purification effect in a shorter time. By spraying the purification reagent onto the filler block in the ecological purification device 1000 and cooperating with the irradiation of the ultraviolet lamp tube 6, efficient purification of the sewage is realized. The water purification assembly sprays the purification reagent onto the filler block in the ecological purification device 1000 in a directional manner, which can be concentrated on the surface of the filler block, so as to increase the contact area and contact time with the sewage, which helps to strengthen the chemical reaction and physical action between the purification reagent and the sewage, and improve the purification effect.

[0060] The function of the water purification assembly is to introduce the purification agent into the ecological purification device 1000 to mix with the sewage, thereby achieving the purification of the sewage. The purification agent can have chemical, biological or other properties, which can promote the decomposition, oxidation, precipitation or removal of pollutants to reduce or eliminate harmful substances in the sewage. In this embodiment, after the purification assembly is started, the first metering pump corresponding to the storage tank storing the purification agent (hydrogen peroxide, chlorine dioxide solution or ozone) is operated, and the worse the monitored water quality, the greater the flow of the first metering pump, and the metering pump corresponding to the storage tank storing other liquids is stopped, so as to uniformly spray hydrogen peroxide, chlorine dioxide solution or ozone onto the filler block through the material conveying pipe 4 and the annular agent spray pipe; at the same time, the wavelength of the lamp is adjusted to the ultraviolet band: 100-400nm, and the worse the monitored water quality, the smaller the wavelength of the light and the greater the light intensity, so as to effectively treat different types of pollutants in the sewage. Ultraviolet light has strong sterilization, disinfection and oxidation effects, which can effectively damage the DNA of microorganisms, kill bacteria, viruses and other microorganisms, and at the same time promote the oxidation reaction of organic matter in the sewage, thereby purifying the sewage.

[0061] The combination of multiple oxidizing agents and ultraviolet technology can further improve the disinfection and purification efficiency of the sewage, and achieve a significant effect improvement that cannot be achieved by using a single oxidizing agent or a single ultraviolet lamp 6. Directing the ultraviolet lamp 6 to irradiate the filler block can further reduce or eliminate microorganisms and pathogens in the sewage under the action of the purification agent; the synergistic effect of the purification agent and ultraviolet light is achieved, the purification agent can react with the pollutants in the sewage, and the ultraviolet light can kill microorganisms, thereby forming a more effective purification environment on the surface of the filler block, improving the purification effect and purification efficiency, and making the sewage treatment process more rapid and effective.

[0062] When the water quality in the ecological purification device 1000 is good, the control assembly adjusts the first metering pump of the water purification assembly to the closed state and simultaneously operates the second metering pump of the repair assembly to spray the probiotic bacteria liquid and beneficial algae liquid onto the filler block. The bacteria-algae symbiotic technology has the ability to proliferate rapidly. In the bacteria-algae symbiotic system, the synergistic interaction between beneficial bacteria and beneficial microalgae affects the physiological activities and metabolism of each other. The most important interaction between algae and bacteria is exchange, including the exchange of CO2 and O2, the exchange of nutrients and the exchange of trace nutrients. Algae, as primary producers, undergo photosynthesis to produce O2, and photosynthetic oxygen serves as an electron acceptor for bacterial aerobic respiration, providing bacteria with metabolic activity; CO2 produced by bacterial metabolism can be used as a carbon source for microalgae; bacterial metabolites such as inorganic nitrogen and phosphorus compounds are used as nutrients required for the growth and metabolism of algae, and photosynthetic organic matter produced by microalgae is partially excreted outside the cell in the form of dissolved carbon, which can also be used as a carbon source for bacteria. At the same time, a large number of studies have shown that microalgae obtain necessary growth-promoting factors such as vitamins, biotin, thiamine, and cobalamin through symbiotic relationships with bacteria. Therefore, the bacteria-algae symbiotic system has more vigorous growth and metabolic activity than single bacteria or single algae systems, and can achieve high-speed "doubling" under suitable environmental conditions. The rapidly proliferating probiotic bacteria and beneficial microalgae are introduced into the surface water body, which is beneficial to the construction of the surface water body food chain and the restoration of the water ecological system balance.

[0063] In the present embodiment, a plurality of lamp tube mounting racks are arranged inside the barrel body, and a plurality of ultraviolet lamps are respectively installed on the lamp tube mounting racks to be fixed inside the chamber of the ecological purification device. The control assembly can regulate the illumination wavelength adjustment range of the ultraviolet lamp 6 to be 100-760 nm, and the illumination intensity adjustment range to be 50-5000 μW / cm 2 When the water quality in the ecological purification device 1000 is good, the control assembly adjusts the illumination wavelength range of the ultraviolet lamp tube 6 to be 400-760 nm. Ultraviolet light has the ability to kill bacteria, disinfect, and oxidize, and can also specifically treat organic matter and new pollutants in sewage, especially has good treatment effect on persistent organic pollutants, antibiotics, endocrine disruptors and other new pollutants, thereby achieving ecological restoration effect. Realize the accurate treatment of microorganisms and organic pollutants in sewage. This technical effect can provide the most suitable illumination conditions according to different situations, thereby enhancing the treatment effect of the ecological purification device 1000 and ensuring that the water body is effectively purified and ecologically restored.

[0064] In this embodiment, the control component initiates the detection component to monitor the purification reagents and / or microbial populations in the storage tank; the control component analyzes the monitoring results of the detection component to determine whether to issue a liquid supplement prompt to the staff. Several storage tanks are used to store hydrogen peroxide, chlorine dioxide solution, ozone, probiotic liquid, and beneficial algae liquid in a classified manner; a liquid level detector electrically connected to the electric control box 3 is arranged in the storage tank, and when the actual liquid level is lower than 20% of the full tank liquid level, the electric control box 3 will issue a liquid supplement prompt to the maintenance personnel.

[0065] In this scheme, the water quality in the ecological purification device 1000 is monitored by the detection component, and the purification reagents and / or microbial populations in the storage tank are also monitored during the treatment process to realize the monitoring and management of the sewage treatment process. Through regular or real-time monitoring, the purification effect and water quality change of the sewage can be understood, which helps to evaluate whether the sewage treatment effect meets the expectation and whether further treatment or adjustment is needed. If the detection result shows that the reagent concentration is insufficient or the microbial population state is not ideal, the control component can issue a liquid supplement prompt and specific treatment suggestions to the staff. This helps to ensure the continuous operation and effect of the ecological purification device 1000, can improve the stability, efficiency and effect of the sewage treatment, and at the same time reduces manual intervention and saves manpower.

[0066] In the present embodiment, the ecological purification device 1000 is provided with a workbench 1, a floating body 12, a depth adjusting rod 15, a barrel 2, a flow guide bottom plate 9 and other components, so that it can meet the operation requirements under various conditions such as different water depths and different depths of river discharge outlets. The electric control box 3, the storage tank 7, the metering pump 5 and other devices are arranged on the upper surface of the workbench 1, and the material conveying pipe 4 penetrates the workbench 1 to convey the material in the storage tank 7 to the annular infusion pipe in the barrel 2. The ecological purification device 1000 also includes a push flow assembly 10 made of corrosion-resistant steel material; in other alternative embodiments, the push flow assembly 10 can also be selected from other beneficial materials. The push flow assembly 10 includes a rotating motor 102, a speed regulating hand wheel 103, a connecting rod 101 and a push flow impeller 104. The speed regulating hand wheel 103 is connected with the rotating motor 102, and the rotating motor 102 is connected with the electric control box 3. The rotating motor 102 is arranged on the surface of the workbench 1. One end of the connecting rod 101 above the workbench 1 is connected with the outlet end of the rotating motor 102, and the other end of the connecting rod 101 inside the cavity of the barrel 2 is connected and fixed with the push flow impeller 104. The connecting rod 101 can be elongated and compressed along its axis direction. In the height direction of the barrel 2, the bottom of the push flow impeller 104 is higher than the top of the ultraviolet lamp 6. The push flow assembly 10 is used to promote the movement and mixing of water flow during sewage treatment, so as to achieve more uniform mixing, purification and repair effects of the reagent. The direction and speed of the rotating motor 102 can be adjusted. The rotating motor 102 drives the movement of the push flow assembly 10. The speed regulating hand wheel 103 is connected with the rotating motor 102, which can adjust the speed of the motor, so as to control the movement speed of the push flow impeller 104, so that the water flow can be moderately stirred to achieve an optimized mixing effect. The design of the connecting rod 101 allows it to be elongated and compressed along the axis direction. This design allows the connecting rod 101 to be adjusted as needed to adapt to different water level changes, so that the push flow impeller 104 always stays in the right place. The push flow impeller 104 is located in the cavity of the barrel 2, and its bottom is higher than the top of the ultraviolet lamp 6. This design allows the push flow impeller 104 to produce stirring effect in the water flow in the device without interfering with the normal operation of the ultraviolet lamp 6, thereby improving the purification and repair effect of the sewage, helping to achieve optimized circulation of the water flow in the device, ensuring uniform distribution and action of the reagent, and achieving better treatment effect.

[0067] In the present embodiment, the ecological purification device is also provided with inner and outer flow uniformizing plates, the inner side wall of the cylinder is fixedly connected with a plurality of inner flow uniformizing plates arranged in a circumferential array for disturbing the flow of water inside the cylinder 2, further promoting the flow of sewage in the cylinder 2 and the mixing of the sewage with the medicament or probiotic liquid and beneficial algal liquid, a plurality of filler blocks and a plurality of lamp tube mounting racks are fixedly arranged between the plurality of inner flow uniformizing plates; the outer side wall of the cylinder 2 is fixedly connected with a plurality of outer flow uniformizing plates arranged in a circumferential array for disturbing the flow of water outside the cylinder 2 and disturbing the flow of water that has been purified or repaired and discharged from the cylinder 2, so that the water can be quickly and uniformly dispersed in the external sewage.

[0068] In the present embodiment, the river outlet double-mode water quality purification and ecological reconstruction method further comprises: the control assembly starts the detection assembly to monitor the flow velocity of the water inside the ecological purification device 1000; the control assembly determines whether to send a cleaning reminder to the worker according to the monitoring result of the detection assembly. When the monitoring probe 8 monitors that the flow rate of the water in the cylinder 2 of the ecological purification device 1000 is low, it indicates that a large amount of floating dregs is intercepted outside the filter screen 13 for water flow circulation, at this time the electric control box 3 sends a dreg fishing prompt to the maintenance personnel, who should timely fish out the floating dregs through the fishing hole. Through the warning, the inspection, maintenance and cleaning of the ecological purification device 1000 can be quickly realized to ensure the smooth flow of water and good treatment effect, which helps to reduce equipment failure and downtime, and at the same time improves the reliability and maintenance efficiency of the sewage treatment system.

[0069] In the present embodiment, the adjusting rods 15 connect the workbench 1, the cylinder 2 and the flow guide bottom plate 9, and the control assembly adjusts the height of the adjusting rods 15 of the sewage purification device to change the size of the upper opening and the size of the bottom opening of the purification device. The height of the adjusting rods 15 of the sewage purification device is adjusted along the circumferential direction of the workbench 1, and a plurality of adjusting rods 15 are arranged at intervals; and each adjusting rod 15 is slidably connected to the workbench 1, the cylinder 2 and the flow guide bottom plate 9 in turn. The design of the adjusting rods 15 allows the height between the workbench 1, the cylinder 2 and the flow guide bottom plate 9 to be adjusted, and by adjusting the length of the adjusting rods 15, the relative positions of the various parts of the device can be changed, such as adjusting the height difference between the cylinder and the workbench 1, and the height difference between the flow guide bottom plate 9 and the cylinder 2, etc. This height adjustment design can adapt to different water level conditions and ensure that the device can always operate normally without being affected by the water level. The sliding connection of the adjusting rods 15 allows the workbench 1, the cylinder 2 and the flow guide bottom plate 9 to be stably connected together. This design ensures that the various components of the device can be tightly matched and will not loosen or fall off, improving the stability and reliability of the device and making it easier to adjust the height of the device. The maintenance personnel can adjust the height of the device by adjusting the length of the adjusting rods 15, without the need for complex operation steps, saving operation time and effort.

[0070] The ecological purification device 1000 discharges the sewage treated by purification or containing microbial population from the bottom opening thereof and diffuses to the surface water body in the down-dip direction through the diversion bottom plate 9. By the design of the diversion bottom plate 9, the sewage can be diffused to the surface water body in the down-dip direction, and the sewage treated by purification or containing microbial population can be discharged from the bottom opening. The discharged sewage is guided by the diversion bottom plate 9 at the bottom, so that it is diffused in the down-dip direction at the position of the discharge port. The design of the diversion bottom plate 9 can be adjusted as needed to ensure that the discharged water flow treated by purification or repair can be properly dispersed and diffused without being concentrated in a certain area, which helps to quickly dilute and disperse the discharged water body, thereby improving the purification and repair effect.
