I. Product Introduction
The energy management and energy-saving analysis system is an energy data monitoring and energy-saving analysis system developed for municipal wastewater treatment plants, industrial wastewater treatment stations, and wastewater pumping stations. The system collects data from electric energy meters, flow meters,PLCcontrol systems, andSCADAmonitoring systems, and performs centralized management and analysis of electricity consumption, water consumption, chemical consumption, and the operating conditions of major equipment during the wastewater treatment process.
The system can combine wastewater treatment volume, equipment operating time, process parameters, and operating load to analyze energy consumption across different process units, equipment, and time periods, identify energy consumption anomalies and potential energy-saving opportunities, and provide data support for equipment operation optimization, energy management, and operating cost control.
For major energy-consuming links such as water pumps, blowers, aeration systems, chemical dosing systems, and sludge dewatering systems, the system can conduct operating efficiency analysis based on on-site data and process conditions, and propose corresponding optimization suggestions. Where on-site control interfaces are available, process verification has been completed, and safety conditions are met, it can be further integrated with automatic control systems to achieve energy-saving control in specific scenarios.
II. Main Functions
1. Energy Consumption Data Collection and Management
Unified collection and management of major energy consumption data in wastewater plants, establishing an energy consumption data system at the plant, process unit, and equipment levels.
Main functions include:
l Collection of electric energy, water volume, and other configured energy data
l Access to operating status, operating time, and load data of major equipment
l Classified management by plant, process area, equipment, and time period
l Real-time display and historical query of energy consumption data
l Energy consumption data aggregation, statistics, and trend analysis
l Alerts for data missing, abnormal fluctuations, and other conditions (configured per project)
Data can come from smart meters, flow meters,PLC,SCADA, or other systems with corresponding data interfaces. The specific collection scope depends on on-site instrument configuration and data access conditions.
2. Itemized Energy Consumption Statistics and Visualization
Itemized statistics of plant-wide energy consumption help management personnel understand the energy consumption composition of different process links and equipment.
Main statistical dimensions include:
l Total plant electricity consumption and water consumption
l Energy consumption of process units such as influent lifting, aeration, and sludge treatment
l Energy consumption of major equipment such as water pumps, blowers, mixers, and dewatering equipment
l Energy consumption by shift, day, week, month, and year
l Energy consumption proportion of each process unit and equipment
l Energy consumption comparison among different sites (applicable to multi-site projects)
The system can display relevant data through trend charts, statistical charts, energy composition charts, and management dashboards, helping management personnel quickly grasp the distribution of energy consumption.
3. Energy Consumption Analysis per Unit Treatment Volume
Simply comparing total electricity consumption cannot accurately determine the operating efficiency of a wastewater plant. The system can combine wastewater treatment volume to conduct statistics and comparisons of energy consumption per unit treatment volume.
Main analysis indicators include:
l Electricity consumption per unit wastewater treatment volume
l Energy consumption per unit treatment volume of different process units
l Changes in energy consumption across different time periods
l Energy consumption comparison under different sites or operating conditions
l Relationship between energy consumption changes and treated water volume and equipment load
Relevant indicators can be defined according to the project's unified statistical criteria, and analysis can be conducted in combination with influent water quality, treatment process, effluent requirements, and actual operating load, avoiding judging energy-saving effects solely by total electricity consumption.
4. Analysis of Major Energy-Consuming Equipment
For major energy-consuming equipment in the wastewater treatment process, analyze the relationship among operating time, load, energy consumption, and process requirements.
Water pump system:
l Statistics on operating time and energy consumption of lifting pumps, return pumps, and other water pumps
l Analysis of operating conditions under different water volumes and liquid level conditions
l Assist in identifying long-time operation, frequent start-stop, or low operating efficiency conditions
l Provide a basis for optimizing pump operation combinations and variable-frequency regulation
Blower and aeration system:
l Statistics on blower operating time, electricity consumption, and load changes
l Conduct analysis in combination with available data such as dissolved oxygen (DO) and treatment load
l Assist in identifying problems such as excessive aeration, inefficient operation, and unreasonable equipment operation
l Provide reference for optimizing aeration volume and blower operation strategies
Sludge treatment system:
l Statistics on operating time and energy consumption of sludge dewatering equipment
l Conduct analysis in combination with sludge treatment volume and related process data
l Assist in evaluating equipment operation scheduling and treatment efficiency
Chemical dosing system:
l Statistics on chemical dosage and related equipment operation data
l Analyze changes in chemical consumption in combination with treated water volume and available water quality data
l Provide a basis for evaluating dosing strategies and controlling chemical costs
Specific analysis indicators depend on equipment type, metering conditions, and data available on site.
5. Energy Consumption Anomaly Identification and Early Warning
Through historical energy consumption data, operating status, and preset thresholds, provide alerts for abnormal energy consumption changes, helping management personnel promptly identify potential problems.
Main functions include:
l Alerts for energy consumption exceeding limits or abnormal fluctuations
l Identification of abnormal energy consumption per unit treatment volume
l Alerts for long equipment operating time or abnormal operating time
l Correlation analysis between equipment operating status and energy consumption data
l Comparison of same-period data, historical benchmarks, and target values
l Query and handling tracking of abnormal records
Early warning rules can use fixed thresholds, historical benchmarks, or analysis rules configured for the project. More complex anomaly detection and predictive analysis can be configured according to project requirements and need to be verified against actual data.
6. Energy-Saving Optimization Suggestions
Combining energy consumption data, equipment operating status, and process requirements, assist management personnel in identifying energy-saving opportunities and form targeted optimization suggestions.
Optimization directions include:
l Optimization of water pump operation combinations and operating periods
l Matching of blower operating load with aeration demand
l Optimization of operating parameters of variable-frequency equipment
l Operation scheduling and chemical consumption analysis of dosing equipment
l Optimization of sludge dewatering equipment operation plans
l Key monitoring and maintenance suggestions for high energy-consuming equipment
l Energy consumption comparison of different operating schemes
The optimization suggestions provided by the system should be evaluated in combination with treatment process, equipment performance, effluent requirements, and on-site safety constraints. Necessary aeration volume should not be reduced, chemical dosing should not be decreased, or wastewater treatment effects should not be affected simply to reduce energy consumption.
7. Energy-Saving Effect Evaluation and Report Management
Compare energy consumption data before and after the implementation of energy-saving measures to assist in evaluating the actual effect of optimization measures.
Main functions include:
l Energy-saving target and energy consumption baseline management
l Comparison of energy consumption data before and after optimization
l Analysis of changes in energy consumption per unit treatment volume
l Statistics on energy-saving effects of major equipment and process units
l Summary of energy consumption trends and abnormal conditions
l Generation of daily, weekly, monthly, and custom reports
Energy-saving effect evaluation should consider factors such as treated water volume, influent water quality, process load, season, and operating conditions as much as possible, avoiding directly attributing energy consumption differences caused by operating condition changes to energy-saving results.
8. Linkage with Automatic Control System
The system can be integrated withPLC,SCADA, and process intelligent analysis modules according to project needs, and use energy consumption analysis results for operating strategy optimization.
A phased implementation approach can be adopted:
l Phase 1: Energy consumption monitoring. Establish energy consumption data collection, itemized statistics, and trend analysis.
l Phase 2: Energy consumption analysis. Combine treatment volume, equipment operating status, and process data to identify anomalies and energy-saving opportunities.
l Phase 3: Strategy optimization. Form equipment operation optimization plans evaluated on site based on analysis results.
l Phase 4: Automatic optimization in specific scenarios (optional). On the premise of reliable data, control interfaces, process verification, and safety protection, connect verified optimization strategies to the automatic control system.
On-sitePLCcontinues to be responsible for equipment start-stop, interlocking, protection, and key control logic. The energy consumption analysis system is responsible for data analysis and optimization support and should not bypass on-site protection logic to directly control equipment.
