CW-MFC Electrode Parameter Optimization Data for Low-Temperature Wastewater Treatment

9.5 KB of experimental data from a study optimizing a constructed wetland-microbial fuel cell (CW-MFC) for rural domestic wastewater treatment under low-temperature winter conditions. The dataset, authored by Tuodi Zhang and last updated in May 2026, contains results from a response surface methodology (RSM) experiment varying electrode plate projection coefficient, inter-electrode distance, and external resistance to maximize COD removal efficiency.

Use Cases

• Modeling the relationship between electrode parameters and COD removal efficiency based on the described RSM experiment.
• Benchmarking the performance of CW-MFC systems against standalone constructed wetlands using the provided effluent COD concentration data.
• Optimizing electrode configuration for bioelectrochemical wastewater treatment systems based on the reported optimal parameters (PC=0.33, ID=272.94 mm, ER=1619.31 Ω).

Strengths

• Includes specific performance metrics, such as effluent COD concentrations ranging from 18.81 to 54.06 mg/L and a maximum COD removal efficiency of 89.14%.
• Reports a model-predicted value (88.06%) with a deviation of <1.2%, suggesting the experimental data validated the statistical model.
• Data is associated with a specific experimental setup (vertical-flow CW-MFC with Acorus calamus) and environmental condition (low-temperature winter).

Limitations

• Row count is unknown, which may limit suitability assessment for statistical modeling.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (9.5 KB), indicating limited scope and likely a single experimental study.
