Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a full-process digital management and control integrated system for tunnel sewage treatment. Background Art

[0002] The tunnel sewage treatment system is an important environmental protection project. Through reasonable design and scientific operation and management, it can effectively remove pollutants in tunnel sewage and protect groundwater resources and people's health. In future tunnel projects, attention should be paid to the construction and operation management of tunnel sewage treatment systems to contribute to sustainable development and environmental protection.

[0003] In the process of using the existing tunnel sewage treatment system, it is usually necessary to collect tunnel sewage, collect it in the sedimentation tank and then precipitate it. After the sludge is precipitated, the sewage and the sludge are separated, and the sewage is subsequently treated with drugs to ensure that the pH value and water quality are within the normal range. The sludge is also dried. The intelligence of these treatment equipment is usually not high enough. Since the sludge content and the pH value of the sewage in the tunnel are different during each treatment process, the equipment either relies on the experience of personnel to add chemicals or adds them quantitatively according to relevant requirements when performing batch sewage treatment. Therefore, the amount of chemicals added by the equipment each time may not meet the treatment standards, which may easily lead to poor sewage treatment effect. If the amount of chemicals is too large, it will cause waste of chemicals. If the amount of chemicals is too small, the sewage treatment effect cannot meet the demand. In view of the shortcomings of the prior art, the present invention provides a full-process digital management and control integrated system for tunnel sewage treatment to solve the above problems.

[0031] The embodiment of the present application solves the problem that the existing tunnel sewage treatment system is usually not intelligent enough by providing a full-process digital management and control integrated system for tunnel sewage treatment. Since the degree of sludge contained in the tunnel sewage and the pH value of the sewage are different during each treatment process, and the equipment either relies on personnel experience to add chemicals or adds them quantitatively according to relevant requirements when performing batch sewage treatment, the amount of chemicals added by the equipment each time may not meet the treatment standards, which may easily lead to poor sewage treatment effects.

[0043] The tunnel sewage treatment full-process digital control integrated system consists of three core parts: data acquisition system, processing unit control system and display system;

[0044] The specific steps and processes for achieving full process control of the tunnel sewage treatment system are:

[0045] 1. System startup and initialization

[0046] System startup:

[0047] The operator starts the entire sewage treatment system through the remote control system or the on-site control panel. The system automatically initializes and checks the status of each device to ensure that it is in standby or operational status.

[0048] Data acquisition system initialization:

[0049] Sensors such as liquid level meters, electromagnetic flow meters, SS, and pH detectors start working to collect initial data, which is then transmitted to the processing unit management and control system in real time.

[0050] 2. Data Collection and Monitoring

[0051] Liquid level data collection:

[0052] Tunnel sewage passes through multiple collection tanks in the tunnel. A level meter, a lifting pump and a monitoring probe are installed in a collection tank near the final tunnel exit to collect high and low liquid level information in the collection tank. The collected water level information and monitoring images are displayed on a display device.

[0053] The liquid level gauges in the four-stage sedimentation tank, regulating sedimentation tank, and sludge storage tank monitor the tank liquid level information in real time. The data is transmitted to the processing unit management and control system to control the operation of the water inlet lift pump and the desludging and purification integrated machine.

[0054] Traffic data collection:

[0055] The electromagnetic flowmeter at the outlet pipe of the water inlet lift pump collects water inlet flow information, and the data is used to monitor the water inlet flow to ensure the normal operation of the system.

[0056] Water quality data collection:

[0057] The SS and pH detectors in the four-stage sedimentation tank collect the main water quality information, and the data is used to adjust the flow of the dosing pump to ensure that the effluent quality meets the standards.

[0058] 3. Processing Unit Control

[0059] Inlet lift pump control:

[0060] The water inlet lift pump is controlled by the liquid level gauge in the water collection tank in the tunnel, so that the subsequent equipment can operate selectively;

[0061] According to the liquid level information in the four-stage sedimentation tank and the regulating sedimentation tank, the start and stop of the two groups of water inlet lift pumps are controlled to ensure the normal operation of the regulating sedimentation tank and subsequent sedimentation and filtration devices.

[0062] Chemical dosing control:

[0063] The water inlet lift pump is linked to the PAC, PAM and pH adjustment chemical dosing device to adjust the flow of the dosing pump according to the water quality information to ensure that the chemical dosage is appropriate.

[0064] Desludging and purification integrated machine control:

[0065] According to the liquid level information in the sludge storage tank, the start and stop of the sludge pump of the desludging and purification integrated machine is controlled to ensure that the sludge is processed and discharged in time.

[0066] 4. Display system monitoring and operation

[0067] Advertising machine display:

[0068] The advertising machine displays the water flow rate, main water quality parameters, process flow, operating status of each equipment and other information in real time. Operators can understand the overall operation of the system through the advertising machine.

[0069] Parameters online setting:

[0070] Operators can set the operating parameters of each device online through the display system, such as adjusting the flow rate of the water inlet lift pump, the flow rate of the dosing pump, etc.

[0071] 5. System maintenance and optimization

[0072] Regular inspection:

[0073] Operators need to inspect the system regularly to ensure the normal operation of each device and check the accuracy of sensors and data acquisition systems.

[0074] Troubleshooting:

[0075] If equipment failure or data abnormality is found, the operator must handle it in a timely manner, such as replacing damaged sensors and repairing faulty equipment.

[0076] System Optimization:

[0077] Based on system operation data and operating experience, the system control strategy is continuously optimized, such as adjusting the dosing ratio, optimizing equipment operating parameters, etc.

[0078] This system starts from the source in the tunnel, while other tunnel treatments usually start from the fourth-level sedimentation tank. This system can monitor the water level inside and outside the tunnel at the same time, and control the number of equipment started in real time according to the water level, which can save energy to the greatest extent than other equipment.

[0079] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
