[0042] In this embodiment, the bar screen 1 is used to collect sewage. A bar screen can be installed inside to intercept and remove large solid particles such as branches, plastic bags, and stones from the sewage, preventing these materials from entering subsequent treatment facilities and causing equipment blockage and damage. The water treated by the bar screen 1 enters the equalization tank 2. The specific functions of the equalization tank 2 include: regulating water flow: By storing and releasing wastewater, the equalization tank can balance the inflow and outflow of water, ensuring the treatment system can operate normally during peak and off-peak periods. Balancing water quality: Through mixing and sedimentation, the equalization tank can make the water entering the treatment system more uniform, reducing the impact of water quality fluctuations on the treatment process. Pretreatment: The equalization tank can also perform preliminary sewage treatment, such as pH adjustment and water temperature control, providing more stable water quality for subsequent treatment processes.

[0043] Taking three sewage treatment devices 3 as an example, the water treated by the equalization tank 2 first enters one of the sewage treatment devices 3 through the control lines of the regulating valve 10 and the electric valve 11 for sewage treatment. When one sewage treatment device 3 has completed water intake and is treating sewage, the other sewage treatment device 3 starts to intake water. By alternating the operation of the two sewage treatment devices 3, the sewage treatment efficiency is ensured. Furthermore, if there is equipment maintenance or failure in one of the two sewage treatment devices 3 that are alternating, the backup sewage treatment device 3 can be activated. In this way, the entire equipment can be in operation with very little downtime.

[0064] The utility model will combine the specific sewage treatment process of the intelligent exchange method sewage treatment device to elaborate the working principle and progressiveness in detail.

[0065] The sewage treatment process is composed of five parts: a grid groove, a regulating pool, a reaction zone of the intelligent exchange method sewage treatment device, a disinfection zone and discharge up to standard.

[0066] In the grid groove 1, sewage first flows into the grid groove, and a grid machine is installed in the groove to fish out gauze, gloves, sanitary napkins, plastic bags and condoms in the sewage, so as to avoid entanglement or blockage of subsequent equipment. The start and stop of the grid machine rely on a liquid level difference meter installed in the groove. When the garbage in the groove increases, the grid bars of the grid machine are blocked, the water level is raised to form a pressure difference signal to a program control system to start the grid machine to transport, fish out the garbage from the sewage, make the sewage flow through the grid machine and enter the subsequent facility regulating pool. When the sewage in the grid groove flows smoothly, the water level decreases, the pressure difference decreases, the signal disappears, and the program control system stops the operation of the grid machine.

[0067] In the adjusting pool 2, the grid tank 1 water enters the adjusting pool, the adjusting pool 2 is to adjust the sewage water volume, uniform sewage quality, avoid the impact of subsequent effects of shock load, prolong the service life of the lifting pump and other basic functions, when the adjusting water capacity is too small, the lifting pump starts frequently and reduces the service life, when the adjusting water capacity is too large, the cost is high and waste is formed, therefore, the water capacity of the adjusting pool is generally designed to be 30% to 40%, and two grids are in parallel. The adjusting pool 2 is provided with a submersible mixer, a liquid level switch, a lifting pump, a PH online detector, a COD online detector and a temperature online detector. The submersible mixer is mainly used for mixing sewage, ensuring uniform mixing of water quality and quantity, preventing sludge deposition, avoiding downtime dredging, and solving the problems of difficult sludge transportation and high disposal cost. The liquid level switch is mainly used for monitoring the water level signal, when the adjusting pool is full, the water level is at the upper point, and the water level signal is sent to the program control system to start the lifting pump to start, and the sewage in the adjusting pool is pumped into the intelligent exchange method sewage treatment equipment for biochemical treatment. With the operation of the lifting pump, the water level of the adjusting pool gradually decreases, and when the water level of the adjusting pool decreases to the lower point, the water level signal is sent to the program control system to stop the lifting pump. The adjusting pool is provided with three liquid level switches, two of which are used alternately, and one is used as a backup. If one of them fails, the backup will replace the normal operation of the failed one, and the backup will automatically replace the backup when the fault is repaired. It has the function of emergency accident. Three lifting pumps are installed in the adjusting pool, two of which are operated alternately, and one is used as a backup. If one of them fails, the backup will replace the normal operation of the failed one, and the backup will automatically replace the backup when the fault is repaired. It has the function of emergency accident. The adjusting pool is provided with a PH online detector, a COD online detector and a temperature online detector, and a flow meter is installed at the outlet of the lifting pump. When the PH value or COD in the sewage exceeds the normal range and the water temperature is lower than 100C, an alarm is immediately given and the relevant personnel are notified to check whether industrial wastewater has entered, so as to avoid causing the subsequent biochemical system to collapse and the growth and reproduction of microorganisms in the biochemical system due to low temperature. The flow meter is used to detect and control the treatment capacity, which cannot be greater than the designed water volume.

[0068] The reaction zone of the intelligent exchange method sewage treatment equipment is composed of three sewage treatment equipment 3, the regulating tank lifting pump outflow enters the intelligent exchange method sewage treatment equipment, the intelligent exchange method sewage treatment equipment is composed of three sets of equipment, i.e., intelligent exchange method sewage treatment equipment A, intelligent exchange method sewage treatment equipment B and intelligent exchange method sewage treatment equipment C, two of which are operated alternately, and one is standby, when one of them fails, the standby replaces the normal operation of the failed one, and the standby is automatically replaced when the failed one is repaired, and has the emergency function of sudden accidents. The three intelligent exchange method sewage treatment equipments are each composed of a reaction zone and a disinfection zone, and no matter which reaction zone and disinfection zone of the intelligent exchange method sewage treatment equipment the sewage enters, the sewage can complete the reaction, sedimentation and outflow in the same reaction zone, and after the sewage is disinfected in the disinfection zone, the sewage can be discharged up to the standard, therefore, the three intelligent exchange method sewage treatment equipments each have six processes, i.e., water inflow process, biochemical process, sedimentation process, water discharge process, disinfection process and up-to-standard discharge process, and do not need primary sedimentation tank, secondary sedimentation tank and reflux pump, and the sewage treatment process is simplified:

[0069] (1) Water inflow process

[0070] The water inflow process is the process of the reaction tank receiving sewage. Before the sewage flows in, it is in the state of water discharge or standby of the previous cycle, and therefore, there is high-concentration activated sludge mixed liquor left in the reaction tank. This is equivalent to the role of sludge reflux in the traditional activated sludge method, and at this time, the water level in the reaction tank is the lowest. During the water inflow time or before the highest water level is reached, the water discharge system of the reaction tank is always in the closed state.

[0071] The water inflow time is 0.5-2 hours (the time can be adjusted through the touch screen of the control panel), and the control method is to send a signal to the PLC through a time relay, and the PLC controls the water inflow time of the lifting pump according to the programmed time signal.

[0072] The water inflow amount is measured by a flowmeter installed after the regulating tank lifting pump, and when the water amount in the reaction zone is full, the flowmeter sends a signal to the PLC to stop the water inflow of the reaction zone.

[0073] On the control panel of the control system of the intelligent exchange method sewage treatment equipment, there are three touch buttons, i.e., “water inflow and aeration, water inflow without aeration, and water inflow and aeration after a certain amount of water inflow”, and one of them can be selected. The high-concentration organic wastewater selects water inflow and aeration, the macromolecular organic wastewater selects water inflow and stirring without aeration, and the organic matter degradation wastewater selects water inflow and stirring with aeration in the later stage.

[0074] (2) Biochemical process

[0075] The reaction time is 1-8 hours (the time can be adjusted through the touch screen of the control panel), and the control method is to send a signal to the PLC through a time relay, and the PLC controls the aeration time of the aeration system according to the programmed time signal.

[0076] (3) Precipitation process

[0077] The precipitation time is 1-2 hours (the time can be adjusted through the touch screen of the control panel), and the control method is to send a signal to the PLC through a time relay, and the PLC controls the precipitation time according to the programmed time signal.

[0078] (4) Drainage process

[0079] The drainage time is 1-2 hours (the time can be adjusted through the touch screen of the control panel), and the control method is to send a signal to the PLC through a time relay, and the PLC controls the drainage time according to the programmed time signal.

[0080] (5) Disinfection process

[0081] The disinfection process is carried out at the same time as the drainage process, and they are started and stopped at the same time. The disinfection time is 1-2 hours (the time can be adjusted through the touch screen of the control panel), and the control method is to send a signal to the PLC through a time relay, and the PLC controls the disinfection time according to the programmed time signal.

[0082] (6) Standard process

[0083] The standard process is a standardized discharge port Bessel tank, which is equipped with an ultrasonic flowmeter, a sampling pump and other equipment. The ultrasonic flowmeter is mainly used for online monitoring of sewage discharge by the environmental protection department, and the sampling pump is mainly used to provide sewage to the COD, ammonia nitrogen, PH, residual chlorine and other online monitoring devices for real-time monitoring of indicators to monitor the quality of discharged water by the environmental protection department.

[0084] (7) Instruments and meters

[0085] In the reaction zone of the intelligent exchange method sewage treatment equipment, there are dissolved oxygen online monitoring instrument, sludge concentration online monitoring instrument, pH value online monitoring instrument, temperature online monitoring instrument, sludge interface instrument, and residual chlorine online monitoring instrument.

[0086] ① The dissolved oxygen instrument monitors in real time and controls the dissolved oxygen between 2-5 mg / L. When the dissolved oxygen is equal to 2 mg / L, the aeration blower is increased to supply oxygen through the frequency conversion command, and when the dissolved oxygen is equal to 5 mg / L, the aeration blower is reduced to supply oxygen through the frequency conversion command, so as to save energy. Therefore, the combination of the dissolved oxygen instrument in the reaction zone of the intelligent exchange method sewage treatment equipment and the frequency converter is to ensure the biochemical treatment of sewage and achieve the purpose of energy saving and consumption reduction.

[0092] ⑦Disinfection zone residual chlorine amount is sent to the PLC by the residual chlorine on-line monitoring instrument, and the PLC ensures that the residual chlorine amount reaches the discharge standard by controlling the dosing amount of the metering pump according to the programmed upper and lower limit values of the residual chlorine amount. For example: the residual chlorine amount of sewage disinfection in a comprehensive hospital is controlled between 2-8mg / L, and the residual chlorine amount of sewage disinfection in a hospital for infectious diseases is controlled between 6.5-10mg / L. The residual chlorine standard of sewage treatment and direct discharge into rivers, lakes, oceans and other natural water bodies should be controlled within 0.5mg / L. The residual chlorine of the effluent water of the water supply unit should be controlled between 0.3-4.0mg / L, and the residual chlorine content at the end of the pipe network should not be less than 0.05mg / L

[0095] (I) Grating pool process control

[0096] 1.1 Grating machine on / off control:

[0097] (1) The operation of the grating machine is controlled by the water level difference signal of the differential pressure gauge installed in the grating tank sent to the PLC, and the PLC controls the grating machine according to the programmed water level difference;

[0098] (2) The management of the grating machine also incorporates intelligent elements.

[0099] (II) Adjusting pool process control

[0100] 2.1 Liquid level switch on / off control.

[0101] The liquid level switch in the conditioning tank works by monitoring the upper and lower water level signals of the tank. When the liquid level rises to the preset upper water level, the liquid level switch sends an on signal to the PLC (Programmable Logic Controller); conversely, when the liquid level drops to the preset lower water level, the liquid level switch sends a stop signal to the PLC. After receiving these signals from the liquid level switch, the PLC will control the related equipment of the conditioning tank (such as water inlet valve, water outlet valve, pump, etc.) according to the logic of the upper and lower water level signals programmed internally, to maintain the stability of the liquid level in the conditioning tank.

[0102] Such a control system ensures that the conditioning tank can operate stably within the set liquid level range, avoiding damage to equipment or reduction in processing efficiency due to excessively high or low liquid levels.

[0103] 2.2 On / Off control of the lift pump.

[0104] The on / off of the lift pump uses intelligent control, which is achieved by integrating multiple sensor signals and the intelligent processing of the PLC (Programmable Logic Controller) to achieve efficient and precise control of the lift pump.

[0107] (2) Flow metering control: Install a flow meter at the back end of the lift pump to monitor the pumped water volume in real time and feed the signal back to the PLC. The PLC intelligently adjusts the operating state of the lift pump according to the programmed water volume range, achieving on-demand start / stop and flow control.

[0108] (3) Time program control: Use a time relay to send a timing signal to the PLC, which automatically controls the on / off of the lift pump according to the preset time program, achieving timed operation and energy-saving management.

[0109] (4) PH value response control: Install a pH meter in the conditioning tank to monitor the water quality acidity and alkalinity in real time and transmit the signal to the PLC. The PLC adjusts the operating state of the lift pump and flow meter through the frequency converter according to the programmed upper and lower limit values of PH, to maintain water quality stability.

[0110] (5) COD monitoring control (Note: revised to be based on COD instead of repeated PH): The COD online monitor is installed in the adjusting tank to monitor the chemical oxygen demand in the water in real time, and the signal is fed back to the PLC. The PLC dynamically adjusts the operating parameters of the lifting pump and flow meter according to the programmed COD threshold value to realize precise control of the water pumping capacity to adapt to the water quality treatment requirements.

[0121] (2) The start / stop state of the reflux pump is sent to the PLC in real time through the signal transmission line.

[0122] (3) The PLC dynamically adjusts the operating state of the mixer according to the signal of the reflux pump to ensure the continuity and efficiency of the sewage treatment.

[0123] 2.3.3 Intelligent Control Logic

[0131] (1) When the PH online monitor detects that the PH value of the adjustment tank is ≤6 or ≥9, it indicates that industrial wastewater is flowing in.

[0132] (2) The PH online monitor immediately sends an abnormal signal to the PLC (Programmable Logic Controller).

[0133] (3) After receiving the abnormal signal, the PLC instructs the booster pump to stop water intake according to the internal programmed logic, to prevent industrial wastewater from further affecting the sewage treatment process.

[0134] 2.4.3 Comprehensive Control and Optimization

[0135] (1) The PLC internal programming contains comprehensive control logic, which can combine the time relay signal, the on / off signal of the backflow pump in the reaction zone, and the signal of the PH online monitor, to achieve comprehensive intelligent control of the adjustment tank and sewage treatment equipment.

[0137] (3) The PH online monitor installed in the adjustment tank monitors the PH value in real time. When PH ≤6 or ≥9, it indicates that industrial wastewater is flowing into the adjustment tank. The PH online monitor sends a signal to the PLC, which instructs the booster pump to stop water intake.

[0138] 2.5 Supervision and Management Control

When the operating status of the conditioning tank or devices is abnormal, the system automatically triggers the early warning or alarm mechanism, promptly notifying relevant personnel for handling, ensuring the safe and stable operation of the system.

[0144] (Three) Intelligent exchange method biochemical reaction zone process control

[0145] 3.1 Inlet water process

[0146] 3.1.1 Inlet water time control

[0147] This embodiment adopts a time relay and PLC (Programmable Logic Controller) linkage control method to achieve precise control of the inlet water time. The time relay sends a signal to the PLC, which controls the inlet water time of the lifting pump according to the preset time signal (range between 0.5-2 hours, and the time can be flexibly adjusted through the touch screen on the control panel), ensuring the accuracy and controllability of the inlet water process.

[0148] 3.1.2 Inlet water volume control

[0149] After the adjustment of the pool lifting pump, the system is installed with a high-precision flow meter for real-time monitoring of the water inflow. When the water volume in the reaction zone reaches the preset full state, the flow meter will send a signal to the PLC, which will immediately stop the water inflow to the reaction zone to prevent excessive water inflow from adversely affecting the treatment effect.

[0150] 3.1.3 Water inflow quality control.

[0151] To meet the treatment needs of wastewater with different water qualities, the control panel of the system is provided with three touch buttons: "influent aeration at the same time, no aeration during inflow, and aeration after a certain amount of inflow". Users can choose the most suitable inflow method according to the specific properties of the wastewater. For example, for high-concentration organic wastewater, the inflow can be aerated at the same time to improve the treatment efficiency; for macromolecular organic wastewater, the inflow can be mixed without aeration; for organic degradation wastewater, the inflow can be aerated after a certain amount to achieve the best treatment effect.

[0152] 3.2 Biochemical process.

[0153] 3.2.1 Reaction time control.

[0154] This embodiment realizes precise control of the reaction time through close cooperation between the time relay and the PLC. The time relay sends a signal to the PLC, which precisely controls the aeration time of the aeration system according to the internally programmed time signal, controlling it between 1 and 8 hours. To meet the needs of different working conditions, users can also easily adjust the specific value of the reaction time through the touch screen on the control panel, achieving flexible control.

[0155] 3.2.2 Sedimentation time control.

[0156] The control of sedimentation time also uses the linkage mode of time relay and PLC. The time relay sends a signal to the PLC, which controls the sedimentation time according to the preset time signal (ranging between 1 and 2 hours, and the time can be adjusted through the touch screen on the control panel) to ensure the stability and controllability of the sedimentation process.

[0157] 3.2.3 Drainage time control.

[0158] The control of drainage time is also realized through the cooperation of the time relay and the PLC. The time relay sends a signal to the PLC, which controls the drainage time according to the programmed time signal (also controlled between 1 and 2 hours, and the time can be adjusted) to ensure the smooth progress of the drainage process.

[0159] 3.2.4 Idle time control.

[0160] In order to optimize the operating efficiency of the biochemical reaction zone, the system also has a control function of idle time. The time relay sends a signal to the PLC, and the PLC controls the idle time according to the preset time signal (the range is between 1 to 2 hours, and the time can be adjusted through the touch screen of the control panel) to make the biochemical reaction zone get sufficient rest and preparation during the idle period, and prepare for the next processing process.

[0161] (IV) Disinfection process.

[0162] 4.1 Disinfection time control.

[0163] The system realizes the synchronous control of disinfection time and drainage time, which ensures the efficiency and accuracy of the disinfection process. Specifically, the time relay sends a signal to the PLC, and the PLC controls the disinfection time according to the internal programmed time signal, ensuring that the disinfection time is within 1 to 2 hours. In order to meet different processing needs and working condition changes, users can easily adjust the specific value of disinfection time through the touch screen on the control panel, realizing flexible disinfection time control. This design not only improves the disinfection efficiency, but also ensures the stability of the disinfection process.

[0164] 4.2 Disinfection water quantity control.

[0165] In order to ensure the effectiveness and economy of disinfection and sterilization, the system precisely controls the disinfection water quantity. After the clean water external pump, a high-precision flowmeter is installed to monitor the flow of the clean water external pump in real time. The PLC controls the hourly flow of the clean water external pump according to the signal sent by the flowmeter, ensuring that it is less than or equal to the effective volume of the disinfection zone. In this way, it can ensure that the effective time of disinfection and sterilization is maintained between 1 to 2 hours, which not only guarantees the disinfection effect, but also avoids resource waste.

[0166] (V) Main index process.

[0167] 5.1 Dissolved oxygen control.

[0168] In order to improve the processing efficiency of the biochemical reaction zone, the system innovatively introduces the dissolved oxygen online monitoring technology. In the reaction zone, a high-precision DO online monitor is installed to monitor the dissolved oxygen content in the reaction zone in real time. When the dissolved oxygen content is equal to 2 mg / L, the DO online monitor will immediately send a signal to the PLC. After receiving the signal, the PLC adjusts the working frequency of the aeration blower through the frequency converter, thereby increasing the aeration amount to increase the dissolved oxygen content in the reaction zone. Conversely, when the dissolved oxygen content reaches 5 mg / L, the DO online monitor will also send a signal to the PLC, and the PLC will adjust the aeration blower through the frequency converter to reduce the aeration amount to prevent the dissolved oxygen content from being too high. Through this innovative control strategy, the system can ensure that the dissolved oxygen content in the reaction zone is always controlled between 2 to 5 mg / L, providing the best environmental conditions for biochemical reactions.

[0169] 5.2 Sludge concentration control.

[0170] In order to maintain the best treatment effect of the biochemical reaction zone, the system introduces the sludge concentration online monitoring technology. In the reaction zone, a high-precision sludge concentration online monitor is installed to monitor the sludge concentration in the reaction zone in real time. When the sludge concentration is equal to 2000 mg / L, the sludge concentration online monitor will send a signal to the PLC, and after receiving the signal, the PLC will close the sludge discharge valve to prevent the sludge concentration from being too low to affect the treatment effect. Conversely, when the sludge concentration reaches 6000 mg / L, the sludge concentration online monitor will also send a signal to the PLC, and the PLC will open the sludge discharge valve to timely discharge excess sludge to prevent the sludge concentration from being too high to cause the treatment efficiency to decrease. Through this precise control strategy, the system can ensure that the sludge concentration in the reaction zone is always controlled between 2000 mg / L to 6000 mg / L, providing stable environmental conditions for biochemical reactions.

[0171] 5.3 pH control.

[0172] In order to ensure the normal operation of the biochemical reaction zone, the system introduces the pH value online monitoring technology. In the reaction zone, a high-precision pH value online monitor is installed to monitor the pH value in the reaction zone in real time. When the pH value is equal to 6.5 or equal to 8, it usually means that the biochemical system of the reaction tank has problems, such as pH imbalance, etc. At this time, the pH value online monitor will immediately send a signal to the PLC, and after receiving the signal, the PLC will quickly respond to stop the water feeding operation of the lifting pump. This control measure can effectively prevent the biochemical reaction from failing or the equipment from being damaged due to abnormal pH value, ensuring the stable operation of the system.

[0173] 5.4 Temperature control.

[0174] In the reaction zone, a high-precision temperature online monitor is installed to monitor the water temperature in real time. This measure is crucial for maintaining the optimal conditions for biochemical reactions. When the water temperature reaches 10℃ (this temperature should be abnormally high, and in actual applications, a more reasonable threshold such as 40℃ or higher may be set, as 10℃ is too high for most biochemical reactions) or drops to 35℃ (this temperature may be adjusted according to the specific needs of the biochemical reaction), the temperature online monitor will send a signal to the PLC. After receiving the signal, the PLC will immediately stop the water feeding operation of the lifting pump to prevent the biochemical reaction from failing or the equipment from being damaged due to abnormal temperature.

[0175] 5.5 Residual chlorine amount control.

[0176] In the disinfection zone, a residual chlorine online monitor is installed to monitor the residual chlorine amount in the water in real time. The residual chlorine amount is an important indicator of disinfection effectiveness. The monitor sends real-time signals to the PLC, which adjusts the residual chlorine amount by controlling the dosing amount of the metering pump according to the pre-programmed upper and lower limits of the residual chlorine amount. This control measure ensures that the residual chlorine amount remains within the discharge standard range, ensuring disinfection effectiveness while avoiding waste and environmental pollution.
