The Pilot-scale Experiment is the abbreviation of an intermediate factory test. The Pilot-scale Experiment is a small-scale production simulation test. It is a smaller-scale test of the product before large-scale mass production. It is an indispensable link from small-scale tests to industrial production. The Pilot-scale Experiment is not a one-time verification behavior but a gradual process from small-batch tests to gradually increasing the number of product tests.
Pilot and large-scale application are the key steps for sewage treatment technology to move from laboratory research to practical application, which is of great significance for verifying the feasibility of the technology, optimizing technical parameters, and reducing the risk of practical application.
Pilot research is a small-scale test conducted under an actual production environment, which can fully understand the application effect and economic benefits of the sewage treatment process. If pilot research is not carried out, problems will be encountered in the early stage of engineering construction. These problems will not only bring economic losses to the enterprise but also delay the project's construction progress and lead to project failure.
Sewage treatment is affected by many factors, such as water quality, temperature, season, etc., which may lead to unsatisfactory treatment effects. In pilot research, different environmental conditions can be tested to master the stability of the sewage treatment process.
The best sewage treatment process can be determined and optimized through pilot studies. This can significantly enhance the efficiency of the process, reduce energy consumption and equipment costs, and thus improve economic benefits.
3. Wastewater treatment equipment pilot process and methods
Clear objectives: Determine the purpose of the pilot test, such as verifying process feasibility, optimizing parameters, or testing equipment performance.
Wastewater characteristics analysis: Conduct a detailed wastewater analysis, including water quality (COD, BOD, ammonia nitrogen, total phosphorus, heavy metals, etc.), water volume, pH value, temperature, etc.
Process design: Design the process flow (pretreatment, primary treatment, and post-treatment) based on laboratory research results and wastewater characteristics.
Equipment selection: Select equipment suitable for pilot scale, such as reactors, sedimentation tanks, filters, aeration equipment, etc.
Equipment installation: Install the equipment according to the design drawings and ensure that each unit (such as grille, regulating tank, bioreactor, sedimentation tank, etc.) is connected correctly.
Instrument configuration: Install monitoring instruments (such as pH meter, flow meter, dissolved oxygen meter, etc.) to monitor operating parameters in real-time.
System debugging: Perform no-load debugging on the equipment to check the equipment operation status and instrument accuracy.
Trial operation: Start the equipment under low load and gradually adjust the parameters (such as water flow, aeration volume, dosage of reagents, etc.).
Parameter optimization: Optimize the process parameters (reaction time, sludge concentration, pH value, etc.) according to the trial operation results.
Formal operation: Under the optimized parameters, formal operation is used to treat wastewater continuously.
Water quality monitoring: Regularly test the inlet and outlet water quality (such as COD, BOD, ammonia nitrogen, total phosphorus, suspended solids, etc.).
Operation parameter recording: Record key parameters such as flow rate, temperature, pH value, dissolved oxygen, sludge concentration, etc.
Monitor equipment operating status (such as energy consumption, failure rate, processing efficiency, etc.).
Problem identification: Analyze operating data to identify problems in the process or equipment (such as low treatment efficiency, sludge bulking, equipment failure, etc.).
Adjustment and optimization: Adjust process parameters or equipment configuration according to the problem and re-run to verify the effect.
Conduct statistical analysis of operating data to evaluate treatment effects and equipment performance.
Comparative analysis: Compare experimental data with theoretical values, historical data, etc., to determine the differences and reasons.
Model fitting: Fit mathematical models based on experimental data to provide prediction and optimization basis for actual projects.
Economic evaluation: Calculate operating costs (such as energy consumption, reagent costs, maintenance costs, etc.).
Summarize the pilot test results, including process feasibility, optimization parameters, equipment performance, economic analysis, etc., and suggest industrial application suggestions.
Process improvement: further optimize the process design based on the pilot test results.
Industrial design: provide industrial design basis for the process that succeeded in the pilot test.

Pilot studies in sewage treatment have developed to a relatively mature stage, but there is still much room for future development. Among them, the most important trends are green environmental protection and intelligence.
Green environmental protection refers to the use of low-energy consumption, low-emission, and low-pollution technologies in the sewage treatment process. In the future, pilot studies in sewage treatment should pay more attention to green environmental protection, gradually eliminate high-energy consumption, high-emission, and high-pollution technologies, promote green and environmentally friendly technologies, and achieve sustainable development.
Intelligence refers to using advanced sensors, control systems, data processing, and analysis technologies to automate, refine, and optimize sewage treatment processes. In the future, pilot studies in sewage treatment should pay more attention to the research and application of intelligent technologies, create digital sewage treatment systems, and realize lean management of sewage treatment processes.
