A tap water pipe disinfection and discharge system

Abstract

A tap water pipeline disinfection and discharge system includes: a PLC calculation and analysis control module, a chemical dosing module, a pipeline water injection module, a data monitoring module, and a tailwater treatment module. Chemicals and water are added to the pipeline according to a certain flow rate ratio, and the dosing and injection ratios are adjusted in real time based on the set concentration of the disinfectant. Dosing and injection are stopped when the disinfectant concentration at the pipeline end is within the set range, allowing for soaking and disinfection. The tailwater treatment module treats the disinfected tailwater to discharge standards before discharge. This invention integrates pipeline disinfection and tailwater treatment into one system. Intelligent control of the chemical dosage in real time ensures effective disinfection while avoiding overdosing, keeping the cycle and cost of tailwater treatment within a controllable range. Furthermore, ultraviolet catalytic decomposition equipment replaces the traditional chemical dosing method for tailwater treatment, simplifying the treatment process and avoiding secondary pollution while ensuring continuous tailwater treatment and discharge.

Description

Technical Field

[0001] This invention relates to the field of water supply equipment disinfection technology, specifically a tap water pipeline disinfection and discharge system. Background Technology

[0002] Urban tap water is distributed through laid pipes to meet water supply needs. Since these pipes are exposed to air before use, they can accumulate bacteria and viruses from the air or surrounding environment. In poor storage conditions, rodents and other highly virus-carrying organisms may also enter. Therefore, pipes need to be sterilized and disinfected before first use to prevent water contamination. NaClO is a commonly used disinfectant for pipe soaking, but the residual chlorine content in the soaked water is high and cannot be directly discharged; a wastewater treatment process is required to ensure the discharged water meets emission standards.

[0003] Existing technologies often employ quantitative NaClO addition. However, due to variations in the inlet area and length of the pipelines to be treated, the presence of multiple bends and transitions, and the poor flowability of the soaking water during disinfection, a single quantitative addition can lead to uneven NaClO concentration and varying degrees of disinfection within the pipeline, making it difficult to guarantee thorough disinfection. Furthermore, existing technologies separate and operate the chemical disinfection and residual chlorine removal processes in the effluent without data feedback. Pipeline disinfection is primarily controlled by operators based on experience, lacking precise control and exhibiting low levels of automation. This often results in overdosing in an attempt to achieve complete disinfection, posing significant challenges to subsequent residual chlorine removal and increasing effluent treatment costs. If manufacturers, in an effort to control costs and with a sense of complacency, discharge substandard effluent into the environment, it can cause irreversible damage to environmental organisms.

[0004] This invention proposes a disinfection and discharge system for tap water pipelines, which solves the above-mentioned technical problems. Summary of the Invention

[0005] A tap water pipeline disinfection and discharge system includes: a PLC calculation and analysis control module, a chemical dosing module, a pipeline water injection module, a data monitoring module, and a tailwater treatment module. The PLC calculation and analysis control module is connected to the chemical dosing module, the pipeline water injection module, the data monitoring module, and the tailwater treatment module. The data monitoring module includes a chemical dosing monitoring unit, a pipeline front-end water injection monitoring unit, a pipeline end-end water flow detection unit, and a tailwater treatment monitoring unit. The chemical dosing monitoring unit is connected to both the PLC calculation and analysis control module and the chemical dosing module. The pipeline front-end water injection monitoring unit and the pipeline end-end water flow detection unit are installed at the front and end of the pipeline, respectively, and are both connected to the PLC calculation and analysis control module. The tailwater treatment monitoring unit is connected to both the tailwater treatment module and the PLC calculation and analysis control module.

[0006] The drug dosing module is mainly used to add the drug to the pipeline to be disinfected at a certain flow rate and flow rate;

[0007] The pipeline water injection module is mainly used to add water without disinfectant to the pipeline to be disinfected at a certain flow rate and flow rate.

[0008] The data monitoring module is mainly used to monitor various data throughout the disinfection and wastewater treatment process.

[0009] The wastewater treatment module is mainly used to purify the disinfection wastewater in the pipeline.

[0010] The PLC calculation, analysis and control module is used to receive monitoring data from the data monitoring module, and after analysis and calculation, control the amount of disinfectant added in the drug dosing module and control the operation of the effluent treatment module.

[0011] The operation method of the above-mentioned pipeline disinfection and discharge system is as follows:

[0012] Water and disinfectant (NaClO solution or other existing disinfectant products) are injected into the pipe to be disinfected in a certain proportion. The flow rate of the disinfectant, the flow rate and concentration of the water at the front end of the pipe, and the concentration of the disinfectant at the rear end of the pipe are monitored in real time. The amount of disinfectant added is adjusted in real time according to the flow rate of the water in the pipe to keep the ratio of newly added water and disinfectant in the pipe as close as possible to the set value. When the concentration of disinfectant in the water at the end of the pipe reaches the preset value, the addition of water and disinfectant in the pipe is stopped (because once the concentration of disinfectant at the end of the pipe is the same as or close to the set value, it means that the pipe is full of water. Since the amount of water and disinfectant added in the pipe is added in a set proportion, the amount of disinfectant added must also reach the preset value. At this time, the addition of water and disinfectant can be stopped).

[0013] After sealing both ends of the pipe and soaking for the set time, the disinfection wastewater inside the pipe is discharged. At this point, the disinfection work on the inner wall of the pipe is completed. Then, the inner wall of the pipe is flushed with water and the flushing water is discharged. The tailwater discharged from the pipe is treated by the tailwater treatment module until it meets the discharge standards. Finally, the qualified tailwater is discharged into the environment.

[0014] Preferably, the disinfection and discharge system for tap water pipelines includes a disinfectant concentration detector installed at the middle or / and later sections of the pipeline. When the concentration of the disinfectant at the end of the pipeline is the same as or within the allowable error of the concentration at the middle or / and later sections, the addition of disinfectant is stopped.

[0015] Since the concentration of disinfectant in the pipeline is adjusted according to a certain ratio of water flow and disinfectant flow per unit time, the concentration of disinfectant in the pipeline itself has a certain error compared with the set concentration. The concentration of disinfectant in different parts of the pipeline is not uniform in a short period of time. If the set concentration is directly compared with the concentration detected at the end, the error will be further increased, and the true situation in the pipeline cannot be reflected in time. In order to more accurately control the water injection and dosing stop time, the concentration of disinfectant in the middle section or / and the middle and later sections of the pipeline can be used as a substitute for the set value for comparison.

[0016] Preferably, the tap water pipeline disinfection and discharge system further includes one or more of an alarm module, a time calibration module, and an external input preset module. The alarm module, the time calibration module, and the external input preset module are all connected to the PLC calculation, analysis, and control module. The time calibration module is connected to the chemical dosing module, the pipeline water injection module, and the tailwater treatment module, respectively.

[0017] The time calibration module is mainly used to unify the statistical time of the equipment in the system, and to ensure that the corresponding modules execute the control commands sent by the PLC calculation and analysis control module at accurate times.

[0018] The external input preset module is used to input one or more of the following: dosing-water injection time, disinfection soaking time, manual intervention time, liquid discharge time in the pipeline, and tailwater treatment start time.

[0019] The alarm module is used for alarms in unexpected / pre-defined situations. For example, if the valves of the drug dosing module, pipeline water injection module, and tailwater treatment module are opened and closed manually, the alarm information can remind the operator to open, close, or adjust the valves of the corresponding equipment in a timely manner. If the valves of the drug dosing module, pipeline water injection module, and tailwater treatment module are opened and closed by electrical intelligent control and cannot be opened, closed, or adjusted normally, the alarm module can remind the operator to check the fault point in a timely manner or suspend the system operation for thorough investigation. Alternatively, when the monitoring data of the data monitoring module is removed from the normal range, the alarm module can also notify relevant personnel to conduct timely investigation or suspend the operation of the system.

[0020] Preferably, in the aforementioned tap water pipeline disinfection and discharge system, the operating data of the pipeline disinfection and discharge system is uploaded to the cloud. The system operating data can be easily retrieved through data backup in the cloud, making it convenient for government departments to view pipeline disinfection data and effluent treatment data. More importantly, multiple sets of data uploaded to the cloud can be compared and analyzed to provide data support for the subsequent operation and improvement of the system.

[0021] Preferably, in the aforementioned tap water pipeline disinfection and discharge system, a sewage outlet is connected between the pipeline outlet and the wastewater treatment module. The inlet of the sewage outlet is connected to the end of the pipeline, and the outlet is connected to the wastewater treatment module. The data monitoring module further includes a sewage monitoring unit, which is connected to the PLC calculation, analysis, and control module and the sewage outlet. The sewage monitoring unit detects the liquid data discharged from the pipeline, and when the discharge standard is met, the wastewater treatment module can be omitted and the wastewater can be discharged directly.

[0022] Preferably, in the aforementioned tap water pipeline disinfection and discharge system, the discharge outlet includes a first discharge outlet for temporary storage of disinfectant liquid and a second discharge outlet for pipeline flushing water. After the disinfectant liquid is discharged from the pipeline, the inner wall of the pipeline needs to be flushed with water. The disinfectant content in the pipeline flushing water is low; if it meets the discharge standards, it can be discharged directly. If it does not meet the discharge standards, it is treated separately through the tailwater treatment module. Separate storage and treatment of the raw liquid and the pipe wall flushing liquid can save tailwater treatment costs.

[0023] Preferably, in the aforementioned tap water pipeline disinfection and discharge system, the tailwater treatment module performs treatment by adding chemical agents or by a non-chemical method.

[0024] Preferably, in the aforementioned tap water pipeline disinfection and discharge system, when the added disinfectant is NaClO, the wastewater treatment module treats the wastewater by means of ultraviolet irradiation.

[0025] Preferably, in the aforementioned tap water pipeline disinfection and discharge system, the tailwater treatment module is completed by a tailwater treatment device. The tailwater treatment device includes a rear cover, a sleeve, an ultraviolet lamp mounting plate, and an ultraviolet lamp. The ultraviolet lamp mounting plate and the ultraviolet lamp are located within the space enclosed by the rear cover and the sleeve. The ultraviolet lamp is installed and fixed to the ultraviolet lamp mounting plate. The ultraviolet lamp mounting plate is connected to the rear cover and / or the sleeve. The upper end of the sleeve is machined with one or more drain holes 1, and the lower end is provided with a liquid inlet hole.

[0026] Preferably, in the aforementioned tap water pipe disinfection and discharge system, the ultraviolet lamp mounting plate includes an ultraviolet lamp mounting plate body and ultraviolet lamp mounting holes. The ultraviolet lamp mounting plate body is located on the lower surface of the rear cover and the upper surface of the sleeve, and the three are fixedly connected. Rubber gaskets are provided on the surfaces of the ultraviolet lamp mounting plate body, the rear cover, and the sleeve. The ultraviolet lamp mounting holes are used for installing the ultraviolet lamps, and gaskets are provided in the mounting holes. The ultraviolet lamps are installed through friction with the rubber gaskets.

[0027] Preferably, the tap water pipe disinfection and discharge system further includes a UV lamp support plate and reinforcing ribs. The UV lamp support plate has UV lamp support holes and flow holes machined on its surface. The UV lamp support holes correspond one-to-one with the UV lamp mounting plate body, with the former having a smaller diameter than the latter. The upper end of the reinforcing rib is fixed to the UV lamp mounting plate and passes through the surface of the UV lamp support plate, while the lower end is fixed to the bottom end of the sleeve. The upper end of the UV lamp is pressed and fixed in the UV lamp mounting hole, and the lower end with a smaller diameter passes through the UV lamp support hole. The UV lamp can be quickly installed and removed using a non-mechanical installation method. Electrical equipment is installed within the space enclosed by the back cover and the UV lamp mounting plate, and the gaskets at various points serve to prevent water leakage.

[0028] Preferably, in the aforementioned tap water pipeline disinfection and discharge system, the ultraviolet lamp comprises a quartz tube and an ultraviolet lamp, with multiple ultraviolet lamps installed in the quartz tube.

[0029] Preferably, in the aforementioned tap water pipeline disinfection and discharge system, the ultraviolet lamp is a medium-pressure ultraviolet lamp. Under the same light metering conditions, the medium-pressure ultraviolet lamp has a smaller volume, which can improve the compactness of the equipment.

[0030] During the effluent treatment process, water is drawn into the inner cavity of the sleeve from the inlet at the bottom of the equipment by a water pump. While flowing in the inner cavity of the sleeve, NaClO is decomposed into NaCl and O2 by ultraviolet light. When the water quality meets the discharge standard, it is discharged from the drain hole at the top. Multiple experiments were conducted based on the height of the sleeve, the number of ultraviolet lamps, the ultraviolet light dose, and the flow rate of the effluent in the sleeve. Finally, the above parameters were adjusted according to the residual chlorine concentration in the discharge standard, so that the residual chlorine can be decomposed and reduced to below the discharge standard during the period when the effluent continuously rises in the sleeve. In addition, the flow rate of the effluent is adjusted according to the content of harmful components monitored by the effluent treatment monitoring unit to ensure that the flow rate of the water in the sleeve corresponds to the decomposition rate of harmful substances.

[0031] The advantages are as follows:

[0032] The water pipe disinfection and discharge system of the present invention integrates the disinfectant dosing system and the effluent treatment system into one system, realizes information exchange between the two systems, and enables intelligent management and timed start-up of pipe disinfection and effluent treatment through time setting, thus avoiding the phenomenon of effluent accumulation.

[0033] The water pipe disinfection and discharge system of the present invention can control the amount of disinfectant added in real time by the water flow rate in the pipe, which can easily make the concentration of disinfectant in the pipe infinitely close to the set value, thus improving the accuracy of liquid dosing;

[0034] The water pipe disinfection and discharge system involved in this invention can accurately control the timing of water injection and disinfectant addition, avoiding excessive addition that would increase the cost of subsequent wastewater treatment.

[0035] The water supply pipeline disinfection and discharge system involved in this invention further reduces treatment costs by classifying and storing raw wastewater and flushing wastewater for proper disposal and treatment.

[0036] The water supply pipeline disinfection and discharge system of the present invention can adjust the flow rate of the effluent in the effluent treatment equipment in real time by monitoring the concentration of harmful components in the effluent discharge liquid, so as to ensure that the effluent has sufficient treatment time.

[0037] The tailwater treatment equipment in the tap water pipeline disinfection and discharge system of the present invention can disassemble the sleeve and put the remaining part directly into the urban sewage well or sewage outlet for water treatment. It has a variety of practical scenarios and flexible usage methods. At the same time, the equipment has a simple structure and low cost. Attached Figure Description

[0046] The following detailed description, in conjunction with the accompanying drawings, will further illustrate the present invention. Detailed Implementation

[0047] Specific implementation case 1:

[0048] A tap water pipeline disinfection and discharge system includes: a PLC calculation and analysis control module, a chemical dosing module, a pipeline water injection module, a data monitoring module, and a tailwater treatment module. The PLC calculation and analysis control module is connected to the chemical dosing module, the pipeline water injection module, the data monitoring module, and the tailwater treatment module. The data monitoring module includes a chemical dosing monitoring unit, a pipeline front-end water injection monitoring unit, a pipeline end-end water flow detection unit, and a tailwater treatment monitoring unit. The chemical dosing monitoring unit is connected to both the PLC calculation and analysis control module and the chemical dosing module. The pipeline front-end water injection monitoring unit and the pipeline end-end water flow detection unit are installed at the front and end of the pipeline, respectively, and are both connected to the PLC calculation and analysis control module. The tailwater treatment monitoring unit is connected to both the tailwater treatment module and the PLC calculation and analysis control module.

[0049] The drug dosing module is mainly used to add the drug to the pipeline to be disinfected at a certain flow rate and flow rate;

[0050] The pipeline water injection module is mainly used to add water without disinfectant to the pipeline to be disinfected at a certain flow rate and flow rate.

[0051] The data monitoring module is mainly used to monitor various data throughout the disinfection and wastewater treatment process.

[0052] The wastewater treatment module is mainly used to purify the disinfection wastewater in the pipeline.

[0053] The PLC calculation, analysis and control module is used to receive monitoring data from the data monitoring module, and after analysis and calculation, control the amount of disinfectant added in the drug dosing module and control the operation of the effluent treatment module.

[0054] The operation method of the above-mentioned pipeline disinfection and discharge system is as follows:

[0055] See Figure 3 As shown, the concentration of NaClO in the pipeline is set as C, the concentration of NaClO in the NaClO solution storage tank is C0, the concentration of disinfectant in the water at the end of the pipeline is C1, the discharge standard concentration is C2, and the concentration of the treated effluent is C3.

[0056] Water and disinfectant (using NaClO solution as an example, but not limited to any particular type of disinfectant) are injected into the pipe to be disinfected in a certain proportion. The flow rate of the disinfectant Q1 and the flow rate of the water Q2 are monitored in real time. Q1 is adjusted according to Q2 to keep the concentration of the disinfectant in the pipe within the range of the set C value and its vicinity.

[0057] When the concentration of disinfectant in the water at the end of the pipeline is detected to be C1≈C (for example, C1=C±0~5%C), stop adding water and disinfectant to the pipeline (because once the concentration of disinfectant at the end of the pipeline is the same as or close to the set value, it means that the pipeline is full of water. Since the amount of water and disinfectant added to the pipeline is added according to the set ratio, the amount of medicine added must also reach the preset value. At this time, the addition of water and disinfectant can be stopped).

[0058] After sealing both ends of the pipe and soaking for 24 hours (the set time), the disinfection wastewater in the pipe is discharged. At this point, the disinfection work on the inner wall of the pipe is completed. Then, the inner wall of the pipe is flushed with water and the flushing water is discharged. The tailwater discharged from the pipe is treated by the tailwater treatment module. When the concentration of NaClO C3≤C2, the qualified tailwater can be discharged into the environment.

[0059] Specific Implementation Case 2:

[0060] Based on Specific Implementation Case 1, a disinfectant concentration detector can be installed in the middle or / and later sections of the pipeline. When the concentration of the disinfectant at the end of the pipeline is the same as or within the allowable error of the concentration in the middle or / and later sections, the addition of disinfectant will be stopped.

[0061] Since the concentration of disinfectant in the pipeline is adjusted according to a certain ratio of water flow and disinfectant flow per unit time, the concentration of disinfectant in the pipeline itself has a certain error compared with the set concentration. The concentration of disinfectant in different parts of the pipeline is not uniform in a short period of time. If the set concentration is directly compared with the concentration detected at the end, the error will be further increased, and the true situation in the pipeline cannot be reflected in time. In order to more accurately control the water injection and dosing stop time, the concentration of disinfectant in the middle section or / and the middle and later sections of the pipeline can be used as a substitute for the set value for comparison.

[0062] Specific Implementation Case 3:

[0063] Based on Specific Implementation Case 1, the tap water pipeline disinfection and discharge system also includes an alarm module, a time calibration module, and an external input preset module. The alarm module, time calibration module, and external input preset module are all connected to the PLC calculation, analysis, and control module. The time calibration module is connected to the chemical dosing module, the pipeline water injection module, and the tailwater treatment module, respectively.

[0064] The time calibration module is mainly used to unify the statistical time of the equipment in the system, and to ensure that the corresponding modules execute the control commands sent by the PLC calculation and analysis control module at accurate times.

[0065] The external input preset module is used to input one or more of the following: dosing-water injection time, disinfection soaking time, manual intervention time, liquid discharge time in the pipeline, and tailwater treatment start time.

[0066] The alarm module is used for alarms in unexpected / pre-defined situations. For example, if the valves of the drug dosing module, pipeline water injection module, and tailwater treatment module are opened and closed manually, the alarm information can remind the operator to open, close, or adjust the valves of the corresponding equipment in a timely manner. If the valves of the drug dosing module, pipeline water injection module, and tailwater treatment module are opened and closed by electrical intelligent control and cannot be opened, closed, or adjusted normally, the alarm module can remind the operator to check the fault point in a timely manner or suspend the system operation for thorough investigation. Alternatively, when the monitoring data of the data monitoring module is removed from the normal range, the alarm module can also notify relevant personnel to conduct timely investigation or suspend the operation of the system.

[0067] Optionally, the operational data of the aforementioned pipeline disinfection and discharge system can be uploaded to the cloud. The system's operational data can be easily retrieved through cloud data backup, making it convenient for government departments to view pipeline disinfection and effluent treatment data. More importantly, multiple sets of data uploaded to the cloud can be compared and analyzed to provide data support for the subsequent operation and improvement of the system.

[0068] Specific Implementation Case 4:

[0069] Based on Specific Implementation Case 1, a sewage outlet is connected between the water outlet of the tap water pipeline disinfection and discharge system and the tailwater treatment module. The sewage outlet is connected to the PLC calculation and analysis control module. The inlet of the sewage outlet is connected to the end of the pipeline, and the outlet is connected to the tailwater treatment module. The data monitoring module also includes a sewage monitoring unit, which is connected to the PLC calculation and analysis control module and the sewage outlet.

When the discharge standard is met, the tailwater treatment module can be omitted and the liquid can be discharged directly.

[0070] Optionally, the discharge outlet includes a first discharge outlet for temporary storage of disinfectant liquid and a second discharge outlet for pipe flushing water. After the disinfectant liquid in the pipe is discharged, the inner wall of the pipe needs to be flushed with water. The disinfectant content in the pipe flushing water is low. If it meets the discharge standards, it can be discharged directly. If it does not meet the discharge standards, it is treated separately through the tailwater treatment module. Storing and treating the raw liquid and the pipe wall flushing liquid separately can save tailwater treatment costs.

[0071] Specific Implementation Case 5:

[0072] A tap water pipeline disinfection and discharge system includes a PLC calculation and analysis control module, a chemical dosing module, a pipeline water injection module, a data monitoring module, and a tailwater treatment module. The PLC calculation and analysis control module is connected to the chemical dosing module, the pipeline water injection module, the data monitoring module, and the tailwater treatment module. The data monitoring module includes a chemical dosing monitoring unit, a pipeline front-end water injection monitoring unit, a pipeline end water flow detection unit, and a tailwater treatment monitoring unit. The chemical dosing monitoring unit is connected to both the PLC calculation and analysis control module and the chemical dosing module. The pipeline front-end water injection monitoring unit and the pipeline end water flow detection unit are installed at the front and end of the pipeline, respectively, and are both connected to the PLC calculation and analysis control module. The tailwater treatment monitoring unit is connected to both the tailwater treatment module and the PLC calculation and analysis control module. The tailwater treatment module performs disinfection and discharge through chemical dosing or non-chemical dosing methods.

[0073] For example, when the added disinfectant is NaClO, the wastewater treatment module can treat the wastewater by adding alkaline solution or by ultraviolet irradiation.

[0074] Specific Implementation Case 6:

[0075] A wastewater treatment device includes a rear cover 1, a sleeve 2, an ultraviolet lamp mounting plate 3, and an ultraviolet lamp 4. The ultraviolet lamp mounting plate 3 and the ultraviolet lamp 4 are located within the space enclosed by the rear cover 1 and the sleeve 2. The ultraviolet lamp 4 is fixedly installed on the ultraviolet lamp mounting plate 3. Optionally, the ultraviolet lamp mounting plate 3 can be connected to the rear cover 1, the sleeve 2, or both. The upper end of the sleeve 2 is machined with four drain holes 21, and the lower end is provided with one inlet hole 22.

[0076] The UV lamp mounting plate 3 includes a UV lamp mounting plate body 31 and a UV lamp mounting hole 32. The UV lamp mounting plate body 31 is located on the lower plate surface of the rear cover 1 and the upper plate surface of the sleeve 2, and the three are fixedly connected. Rubber gaskets are provided on the plate surfaces of the UV lamp mounting plate body 31, the rear cover 1, and the sleeve 2. The UV lamp mounting hole 32 is used for the installation of the UV lamp 4. The mounting hole 32 is provided with a gasket, and the UV lamp 4 is installed by friction between itself and the rubber gasket.

[0077] Optionally, it also includes a UV lamp support plate 5 and reinforcing ribs 6. The surface of the UV lamp support plate 5 is machined with UV lamp support holes 51 and flow holes 52. The UV lamp support holes 51 correspond one-to-one with the UV lamp mounting plate body 31, and the former has a smaller diameter than the latter. The upper end of the reinforcing rib 6 is fixed to the UV lamp mounting plate 3 and passes through the surface of the UV lamp support plate 5, while the lower end is fixed to the bottom end of the sleeve 2. The upper end of the UV lamp is pressed and fixed in the UV lamp mounting hole 32, and the lower end with a smaller diameter passes through the UV lamp support hole 51. The UV lamp can be quickly installed and removed through a non-mechanical installation method. Electrical equipment is installed in the space enclosed by the rear cover 1 and the UV lamp mounting plate 3, and the gaskets at various points can play a role in preventing water leakage.

[0078] Optionally, the ultraviolet lamp 4 includes a quartz tube 41 and an ultraviolet lamp 42, with 10 ultraviolet lamps 42 installed in the quartz tube 1.

[0079] Optionally, the ultraviolet lamp 4 can be a medium-pressure ultraviolet lamp. Under the same light metering conditions, the medium-pressure ultraviolet lamp has a smaller volume, which can improve the compactness of the equipment.

[0080] During the effluent treatment process, water is drawn into the inner cavity of the sleeve from the inlet at the bottom of the equipment by a pump. While flowing within the sleeve, ultraviolet light decomposes NaClO into NaCl and O2. Once the water quality meets the discharge standards, it is discharged from the drain hole at the top. Multiple experiments were conducted based on the sleeve height, the number of ultraviolet lamps, the ultraviolet light dose, and the flow rate of the effluent within the sleeve. Finally, these parameters were adjusted according to the residual chlorine concentration in the discharge standards, ensuring that the residual chlorine is reduced to below the discharge standards during the continuous upward flow of the effluent within the sleeve. The flow rate of the effluent is adjusted based on the content of harmful components monitored by the effluent treatment monitoring unit, ensuring that the decomposition of harmful substances is completed during the continuous upward flow of water within the sleeve.
