Description

Technical Field

[0001] The present invention belongs to the technical field of sewage treatment, and specifically belongs to an intelligent management and control system for integrated sewage treatment equipment. Background Art

[0002] With the acceleration of urbanization and the continuous expansion of industrial production, sewage treatment issues have become increasingly prominent and have become a key link in environmental protection and sustainable development. The traditional sewage treatment control and management model mainly relies on dedicated personnel on duty. The efficiency and accuracy of this method largely depends on the professional level and experience accumulation of managers. However, human factors often make it difficult to ensure a continuous, stable and efficient sewage treatment process. Especially in the face of complex and changeable sewage quality and treatment requirements, managers may cause improper operations due to lack of experience or misjudgment, which in turn affects the sewage treatment effect.

[0003] In addition, the traditional model lacks real-time and accurate monitoring methods, and cannot provide timely feedback and regulation of various indicators in the sewage treatment process, which not only increases the treatment cost, but may also cause environmental pollution accidents due to untimely or substandard treatment, causing double losses to economic production and the ecological environment. Therefore, it is particularly important to seek a more efficient and intelligent sewage treatment control and management model.

[0004] In recent years, with the rapid development of technologies such as the Internet of Things, automatic control, and artificial intelligence, these emerging technologies have provided strong support for the intelligent transformation of the sewage treatment industry. With the rapid advancement of science and technology, the sewage treatment field will bid farewell to the traditional manual control mode and usher in an era of intelligent control of sewage treatment.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The first purpose of the present invention is to provide an integrated intelligent management and control system for sewage treatment equipment, which can integrate multiple monitoring and control functions to ensure efficient and stable operation during sewage treatment.

DETAILED DESCRIPTION

[0025] The technical scheme of the present invention will be clearly and completely described below in conjunction with specific embodiments, but it will be appreciated by those skilled in the art that the following described embodiments are part of embodiments of the present invention, rather than all embodiments, and are only used to illustrate the present invention, and should not be considered as limiting the scope of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative work, all belong to the scope of protection of the present invention. If specific conditions are not indicated in the embodiments, they are carried out according to normal conditions or conditions recommended by the manufacturer. If the manufacturer is not indicated in the reagents or instruments used, they are all conventional products that can be purchased commercially.

[0026] The intelligent management and control system of the present invention is used to realize centralized monitoring, management and intelligent control of integrated sewage treatment equipment, ensuring efficient operation of sewage treatment and stable compliance of effluent water quality. The system consists of four core parts: operation management and control unit, perception execution unit, field control unit and central management and control unit.

[0027] Among them, the operation control unit can organically combine the perception execution unit, the on-site control unit, and the central control unit to play a connecting role. It can provide automatic control, comprehensive perception, timely response and scientific decision-making for sewage treatment production monitoring, operation scheduling, daily patrols, etc., to achieve visualization, dynamic and standardized management of sewage operation supervision; and improve the operation and maintenance efficiency and standards of sewage treatment equipment. The collected full-cycle data is transmitted to the central control unit and the field control unit in real time through the operation control information data platform of the operation control unit to ensure the accuracy and timeliness of the data; in the central control unit, the central control server is used to store, process and analyze the data, and the full-cycle data is comprehensively evaluated according to the preset control algorithm to generate corresponding control instructions; the generated control instructions are transmitted to the field control unit through the operation control unit, and after the PLC controller 7 of the field control unit receives the instructions, it controls the execution device according to the preset control logic and algorithm to adjust and optimize the sewage treatment process; in the central control unit and the field control unit, the operating status and water quality data of the field equipment are viewed in real time through the monitoring display screen 1. When the water quality data exceeds the preset range or the equipment fails, the system will automatically send an alarm signal to remind the operator to take timely measures to deal with it; in addition, management personnel can also observe and operate the situation of the sewage treatment site through the information terminal.

[0028] The following is combined with Figure 1 Further explanation of this system: Specifically, first, multiple online detection instruments 13 of the sensing execution unit on the integrated sewage treatment equipment 8 are used. The water quality monitoring devices among them are placed at key positions such as the water inlet, reaction tank, sedimentation tank, and water outlet to monitor various water quality indicators in real time, such as dissolved oxygen, ammonia nitrogen, total phosphorus, total nitrogen, etc.; the equipment status monitoring devices are installed on major power-consuming facilities such as blowers, water pumps, and agitators to monitor the energy consumption of the equipment; the process parameter monitoring devices are installed at water storage tanks, reaction tanks, and sedimentation tanks to monitor water level changes, and are installed at pumps and pipelines to monitor pressure changes. Next, the full-cycle data collected in real time by the online detection instrument 13 is transmitted to the central control unit through the communication network. The central control unit is composed of two identical hosts, the engineer station 2 and the operation station 4 in the central control room, which serve as backups for each other. When the system is operating normally, the engineer station 2 is the main station of the central control unit, and the operation station 4 is used as a client for browsing and monitoring. When an abnormality occurs in the engineer station 2, the system will automatically switch the operation station 4 to the system main station to maintain the normal operation of the system; the central control server in the central control unit is used to save various data generated in the system and subsystems such as operating equipment management, fault diagnosis and energy management software; the central control room has a monitoring display screen 1 that displays the operating status and water quality data of the integrated sewage treatment equipment in real time, and can support graphical interface display and alarm information push; the central control unit will conduct a comprehensive and in-depth data analysis on the collected full-cycle data, and issue instructions to the field control unit through a preset algorithm based on the analysis results, and remotely control the on-site execution equipment 8 through the PLC controller 7 in the field control unit. The automatic control dosing module 10 of the execution device in the sensing execution unit adopts the control mode of "feedforward + model + feedback" to realize the refined control process of dosing. Based on deep intelligent dosing, the dosage of the liquid medicine is accurately predicted. According to the changes in the influent flow rate and water quality, the dosage is continuously predicted to effectively control the input of the medicine. Compared with the manual dosing system, it can more effectively ensure the safety of water quality and reduce the consumption of medicine. The precise aeration control module 11 uses the mechanism model process simulation to deeply tap the potential, and guides the aeration adjustment by the influent water volume and water quality. It has a core algorithm that can flexibly respond to different treatment conditions. It applies the "feedforward compensation-cascade feedback" control strategy to control different partitions of the aerobic zone within the optimal range, which can ensure that the effluent meets the standard under the condition of complex and changeable influent water. The sludge return control module 12 optimizes the sludge age selection and control in combination with the actual denitrification and phosphorus removal requirements of sewage treatment; based on the optimal sludge age setting value, the residual sludge discharge is intelligently calculated according to the influent and effluent water quality and quantity; according to the influent and effluent total nitrogen concentration, the sludge return ratio is intelligently calculated.This system ensures high reliability and stability of sewage treatment data transmission, guarantees water quality safety, and timely collects data from integrated sewage treatment equipment, making sewage treatment equipment control more efficient and reducing manual intervention and requirements for on-site work.

[0029] Method of using this system: Use the integrated intelligent management and control system of sewage treatment equipment of the present invention. First, the operator starts the intelligent management and control system at the engineer station 2 to initialize the system; the online data detection instrument 13 in the sensing execution unit starts working, and the full-cycle data of the sewage treatment process is collected in real time through sensors, liquid level meters, and power meters. These instruments include but are not limited to inlet water quality parameters, various index parameters in the treatment process, outlet water quality data, and the operating status of the equipment; and the full-cycle data is transmitted to the central management and control unit through the wireless network / 8-port industrial Ethernet switch 9, and the full-cycle data is deeply analyzed and processed by the engineer station 2 in the central management and control unit, and the data is displayed on the monitoring display screen 1 through the 12-port industrial Ethernet switch 5, so that the operator can monitor the operating status of each facility in real time, as well as parameters such as water level and liquid level; the central management and control unit is also equipped with a central UPS power supply 3 to maintain uninterrupted power supply so that the system can continue. The online data detection instrument 13 also transmits data to the environmental protection supervision platform 6 via a wireless network, providing accurate and timely data support for the environmental protection department, which helps to strengthen the supervision of sewage treatment facilities and ensure the compliance and effectiveness of sewage treatment; and the system will regularly generate compliance reports and provide them to relevant departments or institutions for review.

[0030] The operator can remotely control the PLC controller 7 of this system by replacing the engineer station 2, adjust the parameters of the execution device in the sensing execution unit, and change the operation mode of the sewage treatment equipment; this system can also be set to automatic mode, and automatically adjust the equipment operation according to the preset thresholds and logical judgments in the engineer station 2 to ensure efficient and stable operation of the system.

[0031] In particular, when the engineer station 2 receives the operating status of each facility and detects an abnormal state or finds a fault, an alarm message will be issued. After receiving the alarm message, the operator can immediately send instructions through the 12-port industrial Ethernet switch 5 through the engineer station 2 to remotely control the PLC controller 7 to check the faulty equipment and take corresponding measures to ensure that the system can resume normal operation as soon as possible.

[0032] The data platform for operation and control informationization will conduct in-depth analysis of the collected full-cycle data, generate operation reports and optimization suggestions, and based on the data analysis results, operators can optimize and adjust the system through the engineer station 2 to improve sewage treatment efficiency and reduce energy consumption. With the development of sewage technology and changes in demand, operators can regularly update and upgrade the system to ensure the advancement and reliability of the system.

[0033] In general, this system ensures efficient and stable operation of the sewage treatment process through a combination of real-time monitoring and intelligent management and control, improves the effluent water quality compliance rate, reduces operating costs, realizes unmanned and remote monitoring, and reduces labor costs; through visual monitoring and historical data management, it improves the management efficiency and decision-making level of sewage treatment, and managers can grasp the operation status of the sewage treatment plant at any time, discover problems in time and take measures; through real-time data collection, fault diagnosis and remote monitoring and other functions, the stability and reliability of the system are enhanced. When the system fails, it can be discovered and handled in time to avoid adverse effects on the sewage treatment process.

It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
